Also, in the case that the OTG transceiver handles charger control when connected to USB, a regulator named "ac_draw" can be supplied instead of the custom set_charge callback to control the charger when connected to AC. The check for (transceiver->state == OTG_STATE_B_PERIPHERAL) in otg_is_usb_online is probably too simple, I'm just using this with a peripheral only device and gpio_vbus + bq24022. I'm not sure which other OTG states can supply power.

The other one is accessible through GPIO pin 1. Sadly, this pin is being multiplexed with UART0 input, so enabling it as interrupt source (as implied by the gpio-keys driver) is not possible unless UART0 has been turned off. The later one though is a rather bad idea as the Routerboard is an embedded device with only a single serial port, so it's almost always used as serial console device. This patch adds a driver based on INPUT_POLLDEV, which disables the UART and reconfigures GPIO pin 1 temporarily while reading the button state. This procedure works fine and has been tested as part of another, unpublished driver for this device.

The cxgb3 l2t entry, hwtid, and dst entry were being released before all the iwch_ep references were released. This can cause a crash in t3_l2t_send_slow() and other places where the l2t entry is used. The fix is to defer releasing these resources until all endpoint references are gone. Details: - move flags field to the iwch_ep_common struct. - add a flag indicating resources are to be released. - release resources at endpoint free time instead of close/abort time.

This can race with the task's movement between cgroups. This race can cause an access to freed ca pointer in cpuacct_charge() or access to invalid cgroups pointer of the task. This will not happen with rcu or tree rcu as cpuacct_charge() is called with preemption disabled. However if rcupreempt is used, the race is seen. Thanks to Li Zefan for explaining this. Fix this race by explicitly protecting ca and the hierarchy walk with rcu_read_lock(). Changes for v2: - Update patch descrition (as per Li Zefan's review comments). - Remove comments in cpuacct_charge() which explained why rcu_read_lock() was needed (as per Peter Zijlstra's review comments).

Changelog: v7 - Changed the name of the statistic from utime to user and from stime to system so that in future we could easily add other statistics like irq, softirq, steal times etc easily. v6 - Fixed a bug in the error path of cpuacct_create() (pointed by Li Zefan). v5 - In cpuacct_stats_show(), use cputime64_to_clock_t() since we are operating on a 64bit variable here. v4 - Remove comments in cpuacct_update_stats() which explained why rcu_read_lock() was needed (as per Peter Zijlstra's review comments). - Don't say that percpu_counter_read() is broken in Documentation/cpuacct.txt as per KAMEZAWA Hiroyuki's review comments. v3 - Fix a small race in the cpuacct hierarchy walk. v2 - stime and utime now exported in clock_t units instead of msecs. - Addressed the code review comments from Balbir and Li Zefan. - Moved to -tip tree. v1 - Moved the stime/utime accounting to cpuacct controller.

(somehow, long ago that function got eviscerated) If any cpu in the destination node does not get interrupted by the message and post completion in a reasonable time the hardware should respond to the sender with an error. This function enables such timeouts. Tested on the UV hardware simulator.

This patch also removes a unnecessary refcount bump that pretended to avoid a possible race condition with event delivery and expectation timers (as said, not needed since we hold a reference to the object since until we finish the expectation setup).

When we are woken, we try to push the tail of the log forward to make sure we have space available. Unfortunately, this means that if there is not space available, and everyone who needs space goes to sleep there is no-one left to push the tail of the log to make space available. Once we have a thread waiting for space to become available, the others queue up behind it in a FIFO, and none of them push the tail of the log. This can result in everyone going to sleep in xlog_grant_log_space() if the first sleeper races with the last I/O that moves the tail of the log forward. With no further I/O tomove the tail of the log, there is nothing to wake the sleepers and hence all transactions just stop. Fix this by making sure the xfsaild will create enough space for the transaction that is about to sleep by moving the push target far enough forwards to ensure that that the curent proceeees will have enough space available when it is woken. That is, we push the AIL before we go to sleep. Because we've inserted the log ticket into the queue before we've pushed and gone to sleep, subsequent transactions will wait behind this one. Hence we are guaranteed to have space available when we are woken.

Call xfs_sync_inodes() instead to flush all the delayed allocation blocks out. To do this as efficiently as possible, do it via two passes - one to do an async flush of all the dirty blocks and a second to wait for all the IO to complete. This requires some modification to the xfs-sync_inodes_ag() flush code to do efficiently.

Because we hold page locks and the iolock, the flush won't proceed until after we release these locks. This occurs once we've given up and ENOSPC has been reported. Hence if this one is the only dirty inode in the system, we'll get an ENOSPC prematurely. To fix this, remove the async flush from the allocation routines and move it to the top of the write path where we can do a synchronous flush and retry the write again. Only retry once as a second ENOSPC indicates that we really are ENOSPC. This avoids a page cache deadlock when trying to do this flush synchronously in the allocation layer that was identified by Mikulas Patocka.

This isn't really reliable but used to be the best that could be done due to deadlock potential of waiting for the entire flush. Now the inode flush is safe to execute while we hold page and inode locks, we can wait for all the inodes to flush synchronously. Convert the wait mechanism to a completion to do this efficiently. This should remove all remaining spurious ENOSPC errors from the delayed allocation reservation path. This is extracted almost line for line from a larger patch from Mikulas Patocka.

Hence on the first reservation ENOSPC failure flush all the delayed allocation blocks out of the system and retry. This fixes the last commonly triggered spurious ENOSPC issue that has been reported.

Remove the unneeded mess that is xfs_flush_space() and just call xfs_flush_inodes() directly from xfs_iomap_write_delay(). Also, change the location of the retry label to avoid trying to do EOF preallocation because we don't want to do that at ENOSPC. This enables us to remove the BMAPI_SYNC flag as it is no longer used.

Intel-IOMMU Alignment Issue in dma_pte_clear_range() This issue was pointed out by Linus. In dma_pte_clear_range() in intel-iommu.c start = PAGE_ALIGN(start); end &= PAGE_MASK; npages = (end - start) / VTD_PAGE_SIZE; In partial page case, start could be bigger than end and npages will be negative. Currently the issue doesn't show up as a real bug in because start and end have been aligned to page boundary already by all callers. So the issue has been hidden. But it is dangerous programming practice.

However ACPI handles temperature values with a single decimal place. As a consequence, some implementations use an offset of 273.1 and others use an offset of 273.2. Try to find out which one is being used, to present the most accurate and visually appealing number. Tested on a Sony Vaio PGC-GR214EP (which uses 273.1) and a Lenovo Thinkpad T60p (which uses 273.2).

This theory is supported by the fact that the bad RIP value is a vmalloc address. The immediate fix is to make this a non-init call. (A better long-term fix is of course to wait with init-section unloading until a module's async initcalls have been run, which would allow us to discard this function which is still only run once, after all. Perhaps a new async_initcall() function for the async/module API, if this is needed for other modules in the future?)

This should stop the needless code duplication in this method and so make it about twice smaller than it was; along with simplifying the setup for the method call, this should save both time and space...

However, references to the base of the structure were still using the '&' operator. When the address was used with the ata_id_u32() macro, the compiler used the size of the entire array instead of sizeof(u16) to calculate the offset from the base address. This patch removes the use of the '&' operator from all references of cf_id to fix the bug and remove future confusion.

The function fails because the underlying IPoIB interface is not joined to the broadcast group and therefore the SA does not have a multicast record to take a Q_Key from. The fix is to use lazy Q_Key resolution - cma_set_qkey() will set id_priv->qkey if it was not set, and will be called just before the Q_Key is really required.

In schedule_nes_timer(), we return an error if nes_nic_cm_xmit() returns failure. This is changed to success as skb is being put on the timer routines to be processed later. In send_syn() case, we are indicating connect failure once from nes_connect() and the other when the rexmit retries expires. The other issue is skb->users which we are incrementing before calling nes_nic_cm_xmit() which calls dev_queue_xmit() but in case of failure we are decrementing the skb->users at the same time putting the skb on the rexmit path. Even if dev_queue_xmit() fails, the skb->users is decremented already. We are removing the decrement of skb->users in case of failure from both schedule_nes_timer() as well as from nes_cm_timer_tick(). There is also extra check in nes_cm_timer_tick() for rexmit failure which does a break from the loop is removed. This causes problem as the other nodes have their cm_node->ref_count incremented and are not processed.

A virtual function is a lightweight pci-e function that supports a single queue and shares resources with the 82576 physical function contained within the igb driver. To spawn virtual functions from the igb driver all that is needed is to enable CONFIG_PCI_IOV and have an 82576 Ethernet adapter on a system that supports SR-IOV in the BIOS. The virtual functions will appear after the interface is loaded. Signed-off-by: Alexander Duyck Signed-off-by: Jeff Kirsher Signed-off-by: David S.

To prevent VFs from loading automatically a module parameter "max_vfs" was added so that the number of VFs per PF can be limited. This is especially useful when 4 or more 82576 ports are on the system because otherwise to load all VFs would result in 8 interface per physical port.

In certain cases, cap_prctl returns error > 0 for success. However, the 'no_change' label was always setting error to 0. As a result, for example, 'prctl(CAP_BSET_READ, N)' would always return 0. It should return 1 if a process has N in its bounding set (as by default it does). I'm keeping the no_change label even though it's now functionally the same as 'error'.

The thread is modified so that when it sees a barrier request it waits for all pending IO before the request then submits the barrier and waits for it. (We must wait, otherwise it could be intermixed with following requests.) Errors from the barrier request are recorded in a per-device barrier_error variable. There may be only one barrier request in progress at once. For now, the barrier request is converted to a non-barrier request when sending it to the underlying device. This patch guarantees correct barrier behavior if the underlying device doesn't perform write-back caching. The same requirement existed before barriers were supported in dm. Bottom layer barrier support (sending barriers by target drivers) and handling devices with write-back caches will be done in further patches.

The racing between callbacks can lead to corruption of exception store and it can also mean that exception store callbacks are called twice for the same exception - a likely reason for crashes reported inside pending_complete() / remove_exception(). This patch fixes two problems: 1. job->fn being called from the thread that submitted the job (see above). - Fix: hand over the completion callback to the kcopyd thread. 2. job->fn(read_err, write_err, job->context); in segment_complete reports the error of the last subjob, not the union of all errors. - Fix: pass job->write_err to the callback to report all error bits (it is done already in run_complete_job) Cc: stable@kernel.org Signed-off-by: Mikulas Patocka Signed-off-by: Alasdair G Kergon --- drivers/md/dm-kcopyd.c | 17 +++++++++++------ 1 file changed, 11 insertions(+), 6 deletions(-) diff --git a/drivers/md/dm-kcopyd.c b/drivers/md/dm-kcopyd.c index 9d379070918..3e3fc06cb86 100644 --- a/drivers/md/dm-kcopyd.c +++ b/drivers/md/dm-kcopyd.c @@ -511,13 +511,16 @@ static void segment_complete(int read_err, unsigned long write_err, } else if (atomic_dec_and_test(&job->sub_jobs)) { /* - * To avoid a race we must keep the job around - * until after the notify function has completed. - * Otherwise the client may try and stop the job - * after we've completed. + * Queue the completion callback to the kcopyd thread. + * + * Some callers assume that all the completions are called + * from a single thread and don't race with each other. + * + * We must not call the callback directly here because this + * code may not be executing in the thread. */ - job->fn(read_err, write_err, job->context); - mempool_free(job, job->kc->job_pool); + push(&kc->complete_jobs, job); + wake(kc); } } @@ -530,6 +533,8 @@ static void split_job(struct kcopyd_job *job) { int i; + atomic_inc(&job->kc->nr_jobs); + atomic_set(&job->sub_jobs, SPLIT_COUNT); for (i = 0; i < SPLIT_COUNT; i++) segment_complete(0, 0u, job); -- cgit v1.2.3 From 3217ab97f14c5c8f9f975ed8c40c351164b0b10e Mon Sep 17 00:00:00 2001 From: Vitaliy Gusev Date: Thu, 9 Apr 2009 09:50:35 -0600 Subject: kthread: Don't looking for a task in create_kthread() #2 Remove the unnecessary find_task_by_pid_ns(). kthread() can just use "current" to get the same result.

Unrelated pieces of kernel code thus gained dependencies wherein if one work_on_cpu() caller holds a lock which some other work_on_cpu() callback also takes, the kernel could rarely deadlock. Fix this by creating a short-lived kernel thread for each work_on_cpu() invokation. This is not terribly fast, but the only current caller of work_on_cpu() is pci_call_probe(). It would be nice to find some other way of doing the node-local allocations in the PCI probe code so that we can zap work_on_cpu() altogether. The code there is rather nasty. I can't think of anything simple at this time...

Some of -the tracers that are currently in ftrace include a tracer to -trace context switches, the time it takes for a high priority -task to run after it was woken up, the time interrupts are -disabled, and more (ftrace allows for tracer plugins, which -means that the list of tracers can always grow). - - -The File System ---------------- - -Ftrace uses the debugfs file system to hold the control files as -well as the files to display output. - -To mount the debugfs system: - - # mkdir /debug - # mount -t debugfs nodev /debug - -( Note: it is more common to mount at /sys/kernel/debug, but for - simplicity this document will use /debug) - -That's it! (assuming that you have ftrace configured into your kernel) - -After mounting the debugfs, you can see a directory called -"tracing". This directory contains the control and output files -of ftrace. Here is a list of some of the key files: - - - Note: all time values are in microseconds. - - current_tracer: - - This is used to set or display the current tracer - that is configured. - - available_tracers: - - This holds the different types of tracers that - have been compiled into the kernel. The - tracers listed here can be configured by - echoing their name into current_tracer. - - tracing_enabled: - - This sets or displays whether the current_tracer - is activated and tracing or not. Echo 0 into this - file to disable the tracer or 1 to enable it. - - trace: - - This file holds the output of the trace in a human - readable format (described below). - - latency_trace: - - This file shows the same trace but the information - is organized more to display possible latencies - in the system (described below). - - trace_pipe: - - The output is the same as the "trace" file but this - file is meant to be streamed with live tracing. - Reads from this file will block until new data - is retrieved. Unlike the "trace" and "latency_trace" - files, this file is a consumer. This means reading - from this file causes sequential reads to display - more current data. Once data is read from this - file, it is consumed, and will not be read - again with a sequential read. The "trace" and - "latency_trace" files are static, and if the - tracer is not adding more data, they will display - the same information every time they are read. - - trace_options: - - This file lets the user control the amount of data - that is displayed in one of the above output - files. - - tracing_max_latency: - - Some of the tracers record the max latency. - For example, the time interrupts are disabled. - This time is saved in this file. The max trace - will also be stored, and displayed by either - "trace" or "latency_trace". A new max trace will - only be recorded if the latency is greater than - the value in this file. (in microseconds) - - buffer_size_kb: - - This sets or displays the number of kilobytes each CPU - buffer can hold. The tracer buffers are the same size - for each CPU. The displayed number is the size of the - CPU buffer and not total size of all buffers. The - trace buffers are allocated in pages (blocks of memory - that the kernel uses for allocation, usually 4 KB in size). - If the last page allocated has room for more bytes - than requested, the rest of the page will be used, - making the actual allocation bigger than requested. - ( Note, the size may not be a multiple of the page size - due to buffer managment overhead. ) - - This can only be updated when the current_tracer - is set to "nop". - - tracing_cpumask: - - This is a mask that lets the user only trace - on specified CPUS. The format is a hex string - representing the CPUS. - - set_ftrace_filter: - - When dynamic ftrace is configured in (see the - section below "dynamic ftrace"), the code is dynamically - modified (code text rewrite) to disable calling of the - function profiler (mcount). This lets tracing be configured - in with practically no overhead in performance. This also - has a side effect of enabling or disabling specific functions - to be traced. Echoing names of functions into this file - will limit the trace to only those functions. - - set_ftrace_notrace: - - This has an effect opposite to that of - set_ftrace_filter. Any function that is added here will not - be traced. If a function exists in both set_ftrace_filter - and set_ftrace_notrace, the function will _not_ be traced. - - set_ftrace_pid: - - Have the function tracer only trace a single thread. - - set_graph_function: - - Set a "trigger" function where tracing should start - with the function graph tracer (See the section - "dynamic ftrace" for more details). - - available_filter_functions: - - This lists the functions that ftrace - has processed and can trace. These are the function - names that you can pass to "set_ftrace_filter" or - "set_ftrace_notrace". (See the section "dynamic ftrace" - below for more details.) - - -The Tracers ------------ - -Here is the list of current tracers that may be configured. - - "function" - - Function call tracer to trace all kernel functions. - - "function_graph_tracer" - - Similar to the function tracer except that the - function tracer probes the functions on their entry - whereas the function graph tracer traces on both entry - and exit of the functions. It then provides the ability - to draw a graph of function calls similar to C code - source. - - "sched_switch" - - Traces the context switches and wakeups between tasks. - - "irqsoff" - - Traces the areas that disable interrupts and saves - the trace with the longest max latency. - See tracing_max_latency. When a new max is recorded, - it replaces the old trace. It is best to view this - trace via the latency_trace file. - - "preemptoff" - - Similar to irqsoff but traces and records the amount of - time for which preemption is disabled. - - "preemptirqsoff" - - Similar to irqsoff and preemptoff, but traces and - records the largest time for which irqs and/or preemption - is disabled. - - "wakeup" - - Traces and records the max latency that it takes for - the highest priority task to get scheduled after - it has been woken up. - - "hw-branch-tracer" - - Uses the BTS CPU feature on x86 CPUs to traces all - branches executed. - - "nop" - - This is the "trace nothing" tracer. To remove all - tracers from tracing simply echo "nop" into - current_tracer. - - -Examples of using the tracer ----------------------------- - -Here are typical examples of using the tracers when controlling -them only with the debugfs interface (without using any -user-land utilities). - -Output format: --------------- - -Here is an example of the output format of the file "trace" - - -------- -# tracer: function -# -# TASK-PID CPU# TIMESTAMP FUNCTION -# | | | | | - bash-4251 [01] 10152.583854: path_put <-path_walk - bash-4251 [01] 10152.583855: dput <-path_put - bash-4251 [01] 10152.583855: _atomic_dec_and_lock <-dput - -------- - -A header is printed with the tracer name that is represented by -the trace.

The descriptions of the -tracers will also show an example with ftrace enabled. - - -irqsoff -------- - -When interrupts are disabled, the CPU can not react to any other -external event (besides NMIs and SMIs). This prevents the timer -interrupt from triggering or the mouse interrupt from letting -the kernel know of a new mouse event. The result is a latency -with the reaction time. - -The irqsoff tracer tracks the time for which interrupts are -disabled. When a new maximum latency is hit, the tracer saves -the trace leading up to that latency point so that every time a -new maximum is reached, the old saved trace is discarded and the -new trace is saved. - -To reset the maximum, echo 0 into tracing_max_latency. Here is -an example: - - # echo irqsoff > /debug/tracing/current_tracer - # echo 0 > /debug/tracing/tracing_max_latency - # echo 1 > /debug/tracing/tracing_enabled - # ls -ltr - [...] - # echo 0 > /debug/tracing/tracing_enabled - # cat /debug/tracing/latency_trace -# tracer: irqsoff -# -irqsoff latency trace v1.1.5 on 2.6.26 --------------------------------------------------------------------- - latency: 12 us, #3/3, CPU#1 | (M:preempt VP:0, KP:0, SP:0 HP:0 #P:2) - ----------------- - | task: bash-3730 (uid:0 nice:0 policy:0 rt_prio:0) - ----------------- - => started at: sys_setpgid - => ended at: sys_setpgid - -# _------=> CPU# -# / _-----=> irqs-off -# | / _----=> need-resched -# || / _---=> hardirq/softirq -# ||| / _--=> preempt-depth -# |||| / -# ||||| delay -# cmd pid ||||| time | caller -# \ / ||||| \ | / - bash-3730 1d... 0us : _write_lock_irq (sys_setpgid) - bash-3730 1d..1 1us+: _write_unlock_irq (sys_setpgid) - bash-3730 1d..2 14us : trace_hardirqs_on (sys_setpgid) - - -Here we see that that we had a latency of 12 microsecs (which is -very good).

It -also records the locations, which are added to the -available_filter_functions list. Modules are processed as they -are loaded and before they are executed. When a module is -unloaded, it also removes its functions from the ftrace function -list. This is automatic in the module unload code, and the -module author does not need to worry about it. - -When tracing is enabled, kstop_machine is called to prevent -races with the CPUS executing code being modified (which can -cause the CPU to do undesireable things), and the nops are -patched back to calls. But this time, they do not call mcount -(which is just a function stub). They now call into the ftrace -infrastructure. - -One special side-effect to the recording of the functions being -traced is that we can now selectively choose which functions we -wish to trace and which ones we want the mcount calls to remain -as nops. - -Two files are used, one for enabling and one for disabling the -tracing of specified functions.

Some of +the tracers that are currently in ftrace include a tracer to +trace context switches, the time it takes for a high priority +task to run after it was woken up, the time interrupts are +disabled, and more (ftrace allows for tracer plugins, which +means that the list of tracers can always grow). + + +The File System +--------------- + +Ftrace uses the debugfs file system to hold the control files as +well as the files to display output. + +To mount the debugfs system: + + # mkdir /debug + # mount -t debugfs nodev /debug + +( Note: it is more common to mount at /sys/kernel/debug, but for + simplicity this document will use /debug) + +That's it! (assuming that you have ftrace configured into your kernel) + +After mounting the debugfs, you can see a directory called +"tracing". This directory contains the control and output files +of ftrace. Here is a list of some of the key files: + + + Note: all time values are in microseconds. + + current_tracer: + + This is used to set or display the current tracer + that is configured. + + available_tracers: + + This holds the different types of tracers that + have been compiled into the kernel. The + tracers listed here can be configured by + echoing their name into current_tracer. + + tracing_enabled: + + This sets or displays whether the current_tracer + is activated and tracing or not. Echo 0 into this + file to disable the tracer or 1 to enable it. + + trace: + + This file holds the output of the trace in a human + readable format (described below). + + latency_trace: + + This file shows the same trace but the information + is organized more to display possible latencies + in the system (described below). + + trace_pipe: + + The output is the same as the "trace" file but this + file is meant to be streamed with live tracing. + Reads from this file will block until new data + is retrieved. Unlike the "trace" and "latency_trace" + files, this file is a consumer. This means reading + from this file causes sequential reads to display + more current data. Once data is read from this + file, it is consumed, and will not be read + again with a sequential read. The "trace" and + "latency_trace" files are static, and if the + tracer is not adding more data, they will display + the same information every time they are read. + + trace_options: + + This file lets the user control the amount of data + that is displayed in one of the above output + files. + + tracing_max_latency: + + Some of the tracers record the max latency. + For example, the time interrupts are disabled. + This time is saved in this file. The max trace + will also be stored, and displayed by either + "trace" or "latency_trace". A new max trace will + only be recorded if the latency is greater than + the value in this file. (in microseconds) + + buffer_size_kb: + + This sets or displays the number of kilobytes each CPU + buffer can hold. The tracer buffers are the same size + for each CPU. The displayed number is the size of the + CPU buffer and not total size of all buffers. The + trace buffers are allocated in pages (blocks of memory + that the kernel uses for allocation, usually 4 KB in size). + If the last page allocated has room for more bytes + than requested, the rest of the page will be used, + making the actual allocation bigger than requested. + ( Note, the size may not be a multiple of the page size + due to buffer managment overhead. ) + + This can only be updated when the current_tracer + is set to "nop". + + tracing_cpumask: + + This is a mask that lets the user only trace + on specified CPUS. The format is a hex string + representing the CPUS. + + set_ftrace_filter: + + When dynamic ftrace is configured in (see the + section below "dynamic ftrace"), the code is dynamically + modified (code text rewrite) to disable calling of the + function profiler (mcount). This lets tracing be configured + in with practically no overhead in performance. This also + has a side effect of enabling or disabling specific functions + to be traced. Echoing names of functions into this file + will limit the trace to only those functions. + + set_ftrace_notrace: + + This has an effect opposite to that of + set_ftrace_filter. Any function that is added here will not + be traced. If a function exists in both set_ftrace_filter + and set_ftrace_notrace, the function will _not_ be traced. + + set_ftrace_pid: + + Have the function tracer only trace a single thread. + + set_graph_function: + + Set a "trigger" function where tracing should start + with the function graph tracer (See the section + "dynamic ftrace" for more details). + + available_filter_functions: + + This lists the functions that ftrace + has processed and can trace. These are the function + names that you can pass to "set_ftrace_filter" or + "set_ftrace_notrace". (See the section "dynamic ftrace" + below for more details.) + + +The Tracers +----------- + +Here is the list of current tracers that may be configured. + + "function" + + Function call tracer to trace all kernel functions. + + "function_graph_tracer" + + Similar to the function tracer except that the + function tracer probes the functions on their entry + whereas the function graph tracer traces on both entry + and exit of the functions. It then provides the ability + to draw a graph of function calls similar to C code + source. + + "sched_switch" + + Traces the context switches and wakeups between tasks. + + "irqsoff" + + Traces the areas that disable interrupts and saves + the trace with the longest max latency. + See tracing_max_latency. When a new max is recorded, + it replaces the old trace. It is best to view this + trace via the latency_trace file. + + "preemptoff" + + Similar to irqsoff but traces and records the amount of + time for which preemption is disabled. + + "preemptirqsoff" + + Similar to irqsoff and preemptoff, but traces and + records the largest time for which irqs and/or preemption + is disabled. + + "wakeup" + + Traces and records the max latency that it takes for + the highest priority task to get scheduled after + it has been woken up. + + "hw-branch-tracer" + + Uses the BTS CPU feature on x86 CPUs to traces all + branches executed. + + "nop" + + This is the "trace nothing" tracer. To remove all + tracers from tracing simply echo "nop" into + current_tracer. + + +Examples of using the tracer +---------------------------- + +Here are typical examples of using the tracers when controlling +them only with the debugfs interface (without using any +user-land utilities). + +Output format: +-------------- + +Here is an example of the output format of the file "trace" + + -------- +# tracer: function +# +# TASK-PID CPU# TIMESTAMP FUNCTION +# | | | | | + bash-4251 [01] 10152.583854: path_put <-path_walk + bash-4251 [01] 10152.583855: dput <-path_put + bash-4251 [01] 10152.583855: _atomic_dec_and_lock <-dput + -------- + +A header is printed with the tracer name that is represented by +the trace.

It gives the trace version +and the version of the kernel upon which this was executed on +(2.6.26-rc8). Then it displays the max latency in microsecs (97 +us). The number of trace entries displayed and the total number +recorded (both are three: #3/3). The type of preemption that was +used (PREEMPT). VP, KP, SP, and HP are always zero and are +reserved for later use. #P is the number of online CPUS (#P:2). + +The task is the process that was running when the latency +occurred. (swapper pid: 0). + +The start and stop (the functions in which the interrupts were +disabled and enabled respectively) that caused the latencies: + + apic_timer_interrupt is where the interrupts were disabled. + do_softirq is where they were enabled again. + +The next lines after the header are the trace itself. The header +explains which is which. + + cmd: The name of the process in the trace. + + pid: The PID of that process. + + CPU#: The CPU which the process was running on. + + irqs-off: 'd' interrupts are disabled. '.' otherwise. + Note: If the architecture does not support a way to + read the irq flags variable, an 'X' will always + be printed here. + + need-resched: 'N' task need_resched is set, '.' otherwise. + + hardirq/softirq: + 'H' - hard irq occurred inside a softirq. + 'h' - hard irq is running + 's' - soft irq is running + '.' - normal context. + + preempt-depth: The level of preempt_disabled + +The above is mostly meaningful for kernel developers. + + time: This differs from the trace file output.

The +"FUNCTION" is a misnomer since here it represents the wake ups +and context switches. + +The sched_switch file only lists the wake ups (represented with +'+') and context switches ('==>') with the previous task or +current task first followed by the next task or task waking up. +The format for both of these is PID:KERNEL-PRIO:TASK-STATE. +Remember that the KERNEL-PRIO is the inverse of the actual +priority with zero (0) being the highest priority and the nice +values starting at 100 (nice -20).

The descriptions of the +tracers will also show an example with ftrace enabled. + + +irqsoff +------- + +When interrupts are disabled, the CPU can not react to any other +external event (besides NMIs and SMIs). This prevents the timer +interrupt from triggering or the mouse interrupt from letting +the kernel know of a new mouse event. The result is a latency +with the reaction time. + +The irqsoff tracer tracks the time for which interrupts are +disabled. When a new maximum latency is hit, the tracer saves +the trace leading up to that latency point so that every time a +new maximum is reached, the old saved trace is discarded and the +new trace is saved. + +To reset the maximum, echo 0 into tracing_max_latency.

Before that, the functions being traced still +show that it is not in an interrupt, but we can see from the +functions themselves that this is not the case. + +Notice that __do_softirq when called does not have a +preempt_count. It may seem that we missed a preempt enabling. +What really happened is that the preempt count is held on the +thread's stack and we switched to the softirq stack (4K stacks +in effect). The code does not copy the preempt count, but +because interrupts are disabled, we do not need to worry about +it. Having a tracer like this is good for letting people know +what really happens inside the kernel. + + +preemptirqsoff +-------------- + +Knowing the locations that have interrupts disabled or +preemption disabled for the longest times is helpful. But +sometimes we would like to know when either preemption and/or +interrupts are disabled. + +Consider the following code: + + local_irq_disable(); + call_function_with_irqs_off(); + preempt_disable(); + call_function_with_irqs_and_preemption_off(); + local_irq_enable(); + call_function_with_preemption_off(); + preempt_enable(); + +The irqsoff tracer will record the total length of +call_function_with_irqs_off() and +call_function_with_irqs_and_preemption_off(). + +The preemptoff tracer will record the total length of +call_function_with_irqs_and_preemption_off() and +call_function_with_preemption_off(). + +But neither will trace the time that interrupts and/or +preemption is disabled. This total time is the time that we can +not schedule. To record this time, use the preemptirqsoff +tracer. + +Again, using this trace is much like the irqsoff and preemptoff +tracers. + + # echo preemptirqsoff > /debug/tracing/current_tracer + # echo 0 > /debug/tracing/tracing_max_latency + # echo 1 > /debug/tracing/tracing_enabled + # ls -ltr + [...] + # echo 0 > /debug/tracing/tracing_enabled + # cat /debug/tracing/latency_trace +# tracer: preemptirqsoff +# +preemptirqsoff latency trace v1.1.5 on 2.6.26-rc8 +-------------------------------------------------------------------- + latency: 293 us, #3/3, CPU#0 | (M:preempt VP:0, KP:0, SP:0 HP:0 #P:2) + ----------------- + | task: ls-4860 (uid:0 nice:0 policy:0 rt_prio:0) + ----------------- + => started at: apic_timer_interrupt + => ended at: __do_softirq + +# _------=> CPU# +# / _-----=> irqs-off +# | / _----=> need-resched +# || / _---=> hardirq/softirq +# ||| / _--=> preempt-depth +# |||| / +# ||||| delay +# cmd pid ||||| time | caller +# \ / ||||| \ | / + ls-4860 0d... 0us!: trace_hardirqs_off_thunk (apic_timer_interrupt) + ls-4860 0d.s. 294us : _local_bh_enable (__do_softirq) + ls-4860 0d.s1 294us : trace_preempt_on (__do_softirq) + + + +The trace_hardirqs_off_thunk is called from assembly on x86 when +interrupts are disabled in the assembly code.

This is also known as "schedule +latency". I stress the point that this is about RT tasks. It is +also important to know the scheduling latency of non-RT tasks, +but the average schedule latency is better for non-RT tasks. +Tools like LatencyTop are more appropriate for such +measurements. + +Real-Time environments are interested in the worst case latency. +That is the longest latency it takes for something to happen, +and not the average. We can have a very fast scheduler that may +only have a large latency once in a while, but that would not +work well with Real-Time tasks. The wakeup tracer was designed +to record the worst case wakeups of RT tasks. Non-RT tasks are +not recorded because the tracer only records one worst case and +tracing non-RT tasks that are unpredictable will overwrite the +worst case latency of RT tasks. + +Since this tracer only deals with RT tasks, we will run this +slightly differently than we did with the previous tracers. +Instead of performing an 'ls', we will run 'sleep 1' under +'chrt' which changes the priority of the task. + + # echo wakeup > /debug/tracing/current_tracer + # echo 0 > /debug/tracing/tracing_max_latency + # echo 1 > /debug/tracing/tracing_enabled + # chrt -f 5 sleep 1 + # echo 0 > /debug/tracing/tracing_enabled + # cat /debug/tracing/latency_trace +# tracer: wakeup +# +wakeup latency trace v1.1.5 on 2.6.26-rc8 +-------------------------------------------------------------------- + latency: 4 us, #2/2, CPU#1 | (M:preempt VP:0, KP:0, SP:0 HP:0 #P:2) + ----------------- + | task: sleep-4901 (uid:0 nice:0 policy:1 rt_prio:5) + ----------------- + +# _------=> CPU# +# / _-----=> irqs-off +# | / _----=> need-resched +# || / _---=> hardirq/softirq +# ||| / _--=> preempt-depth +# |||| / +# ||||| delay +# cmd pid ||||| time | caller +# \ / ||||| \ | / + -0 1d.h4 0us+: try_to_wake_up (wake_up_process) + -0 1d..4 4us : schedule (cpu_idle) + + +Running this on an idle system, we see that it only took 4 +microseconds to perform the task switch.

The way +this works is the mcount function call (placed at the start of +every kernel function, produced by the -pg switch in gcc), +starts of pointing to a simple return. (Enabling FTRACE will +include the -pg switch in the compiling of the kernel.) + +At compile time every C file object is run through the +recordmcount.pl script (located in the scripts directory). This +script will process the C object using objdump to find all the +locations in the .text section that call mcount. (Note, only the +.text section is processed, since processing other sections like +.init.text may cause races due to those sections being freed). + +A new section called "__mcount_loc" is created that holds +references to all the mcount call sites in the .text section. +This section is compiled back into the original object. The +final linker will add all these references into a single table. + +On boot up, before SMP is initialized, the dynamic ftrace code +scans this table and updates all the locations into nops. It +also records the locations, which are added to the +available_filter_functions list. Modules are processed as they +are loaded and before they are executed. When a module is +unloaded, it also removes its functions from the ftrace function +list. This is automatic in the module unload code, and the +module author does not need to worry about it. + +When tracing is enabled, kstop_machine is called to prevent +races with the CPUS executing code being modified (which can +cause the CPU to do undesireable things), and the nops are +patched back to calls. But this time, they do not call mcount +(which is just a function stub). They now call into the ftrace +infrastructure. + +One special side-effect to the recording of the functions being +traced is that we can now selectively choose which functions we +wish to trace and which ones we want the mcount calls to remain +as nops. + +Two files are used, one for enabling and one for disabling the +tracing of specified functions.

Introduction +=============== + +kmemtrace helps kernel developers figure out two things: +1) how different allocators (SLAB, SLUB etc.) perform +2) how kernel code allocates memory and how much + +To do this, we trace every allocation and export information to the userspace +through the relay interface. We export things such as the number of requested +bytes, the number of bytes actually allocated (i.e. including internal +fragmentation), whether this is a slab allocation or a plain kmalloc() and so +on. + +The actual analysis is performed by a userspace tool (see section III for +details on where to get it from). It logs the data exported by the kernel, +processes it and (as of writing this) can provide the following information: +- the total amount of memory allocated and fragmentation per call-site +- the amount of memory allocated and fragmentation per allocation +- total memory allocated and fragmentation in the collected dataset +- number of cross-CPU allocation and frees (makes sense in NUMA environments) + +Moreover, it can potentially find inconsistent and erroneous behavior in +kernel code, such as using slab free functions on kmalloc'ed memory or +allocating less memory than requested (but not truly failed allocations). + +kmemtrace also makes provisions for tracing on some arch and analysing the +data on another. + +II. Design and goals +==================== + +kmemtrace was designed to handle rather large amounts of data. Thus, it uses +the relay interface to export whatever is logged to userspace, which then +stores it. Analysis and reporting is done asynchronously, that is, after the +data is collected and stored. By design, it allows one to log and analyse +on different machines and different arches. + +As of writing this, the ABI is not considered stable, though it might not +change much. However, no guarantees are made about compatibility yet. When +deemed stable, the ABI should still allow easy extension while maintaining +backward compatibility. This is described further in Documentation/ABI. + +Summary of design goals: + - allow logging and analysis to be done across different machines + - be fast and anticipate usage in high-load environments (*) + - be reasonably extensible + - make it possible for GNU/Linux distributions to have kmemtrace + included in their repositories + +(*) - one of the reasons Pekka Enberg's original userspace data analysis + tool's code was rewritten from Perl to C (although this is more than a + simple conversion) + + +III. Quick usage guide +====================== + +1) Get a kernel that supports kmemtrace and build it accordingly (i.e. enable +CONFIG_KMEMTRACE). + +2) Get the userspace tool and build it: +$ git-clone git://repo.or.cz/kmemtrace-user.git # current repository +$ cd kmemtrace-user/ +$ ./autogen.sh +$ ./configure +$ make + +3) Boot the kmemtrace-enabled kernel if you haven't, preferably in the +'single' runlevel (so that relay buffers don't fill up easily), and run +kmemtrace: +# '$' does not mean user, but root here. +$ mount -t debugfs none /sys/kernel/debug +$ mount -t proc none /proc +$ cd path/to/kmemtrace-user/ +$ ./kmemtraced +Wait a bit, then stop it with CTRL+C. +$ cat /sys/kernel/debug/kmemtrace/total_overruns # Check if we didn't + # overrun, should + # be zero. +$ (Optionally) [Run kmemtrace_check separately on each cpu[0-9]*.out file to + check its correctness] +$ ./kmemtrace-report + +Now you should have a nice and short summary of how the allocator performs. + +IV. FAQ and known issues +======================== + +Q: 'cat /sys/kernel/debug/kmemtrace/total_overruns' is non-zero, how do I fix +this? Should I worry? +A: If it's non-zero, this affects kmemtrace's accuracy, depending on how +large the number is. You can fix it by supplying a higher +'kmemtrace.subbufs=N' kernel parameter. +--- + +Q: kmemtrace_check reports errors, how do I fix this? Should I worry? +A: This is a bug and should be reported. It can occur for a variety of +reasons: + - possible bugs in relay code + - possible misuse of relay by kmemtrace + - timestamps being collected unorderly +Or you may fix it yourself and send us a patch. +--- + +Q: kmemtrace_report shows many errors, how do I fix this? Should I worry? +A: This is a known issue and I'm working on it. These might be true errors +in kernel code, which may have inconsistent behavior (e.g. allocating memory +with kmem_cache_alloc() and freeing it with kfree()). Pekka Enberg pointed +out this behavior may work with SLAB, but may fail with other allocators. + +It may also be due to lack of tracing in some unusual allocator functions. + +We don't want bug reports regarding this issue yet. +--- + +V.

In Dec 2006 - Jan 2007, using the code from Intel, +Jeff Muizelaar created a tool for tracing MMIO accesses with the Nouveau +project in mind. Since then many people have contributed. + +Mmiotrace was built for reverse engineering any memory-mapped IO device with +the Nouveau project as the first real user. Only x86 and x86_64 architectures +are supported. + +Out-of-tree mmiotrace was originally modified for mainline inclusion and +ftrace framework by Pekka Paalanen . + + +Preparation +----------- + +Mmiotrace feature is compiled in by the CONFIG_MMIOTRACE option. Tracing is +disabled by default, so it is safe to have this set to yes. SMP systems are +supported, but tracing is unreliable and may miss events if more than one CPU +is on-line, therefore mmiotrace takes all but one CPU off-line during run-time +activation. You can re-enable CPUs by hand, but you have been warned, there +is no way to automatically detect if you are losing events due to CPUs racing. + + +Usage Quick Reference +--------------------- + +$ mount -t debugfs debugfs /debug +$ echo mmiotrace > /debug/tracing/current_tracer +$ cat /debug/tracing/trace_pipe > mydump.txt & +Start X or whatever. +$ echo "X is up" > /debug/tracing/trace_marker +$ echo nop > /debug/tracing/current_tracer +Check for lost events. + + +Usage +----- + +Make sure debugfs is mounted to /debug.

It is recommended to place descriptive markers about what you +do. + +Shut down mmiotrace (requires root privileges): +$ echo nop > /debug/tracing/current_tracer +The 'cat' process exits. If it does not, kill it by issuing 'fg' command and +pressing ctrl+c. + +Check that mmiotrace did not lose events due to a buffer filling up. Either +$ grep -i lost mydump.txt +which tells you exactly how many events were lost, or use +$ dmesg +to view your kernel log and look for "mmiotrace has lost events" warning. If +events were lost, the trace is incomplete. You should enlarge the buffers and +try again. Buffers are enlarged by first seeing how large the current buffers +are: +$ cat /debug/tracing/buffer_size_kb +gives you a number. Approximately double this number and write it back, for +instance: +$ echo 128000 > /debug/tracing/buffer_size_kb +Then start again from the top. + +If you are doing a trace for a driver project, e.g. Nouveau, you should also +do the following before sending your results: +$ lspci -vvv > lspci.txt +$ dmesg > dmesg.txt +$ tar zcf pciid-nick-mmiotrace.tar.gz mydump.txt lspci.txt dmesg.txt +and then send the .tar.gz file. The trace compresses considerably. Replace +"pciid" and "nick" with the PCI ID or model name of your piece of hardware +under investigation and your nick name. + + +How Mmiotrace Works +------------------- + +Access to hardware IO-memory is gained by mapping addresses from PCI bus by +calling one of the ioremap_*() functions. Mmiotrace is hooked into the +__ioremap() function and gets called whenever a mapping is created. Mapping is +an event that is recorded into the trace log. Note, that ISA range mappings +are not caught, since the mapping always exists and is returned directly. + +MMIO accesses are recorded via page faults. Just before __ioremap() returns, +the mapped pages are marked as not present. Any access to the pages causes a +fault. The page fault handler calls mmiotrace to handle the fault. Mmiotrace +marks the page present, sets TF flag to achieve single stepping and exits the +fault handler. The instruction that faulted is executed and debug trap is +entered. Here mmiotrace again marks the page as not present. The instruction +is decoded to get the type of operation (read/write), data width and the value +read or written. These are stored to the trace log. + +Setting the page present in the page fault handler has a race condition on SMP +machines. During the single stepping other CPUs may run freely on that page +and events can be missed without a notice. Re-enabling other CPUs during +tracing is discouraged. + + +Trace Log Format +---------------- + +The raw log is text and easily filtered with e.g. grep and awk. One record is +one line in the log. A record starts with a keyword, followed by keyword +dependant arguments. Arguments are separated by a space, or continue until the +end of line. The format for version 20070824 is as follows: + +Explanation Keyword Space separated arguments +--------------------------------------------------------------------------- + +read event R width, timestamp, map id, physical, value, PC, PID +write event W width, timestamp, map id, physical, value, PC, PID +ioremap event MAP timestamp, map id, physical, virtual, length, PC, PID +iounmap event UNMAP timestamp, map id, PC, PID +marker MARK timestamp, text +version VERSION the string "20070824" +info for reader LSPCI one line from lspci -v +PCI address map PCIDEV space separated /proc/bus/pci/devices data +unk. opcode UNKNOWN timestamp, map id, physical, data, PC, PID + +Timestamp is in seconds with decimals.

Mmiotrace is hooked into the -__ioremap() function and gets called whenever a mapping is created. Mapping is -an event that is recorded into the trace log. Note, that ISA range mappings -are not caught, since the mapping always exists and is returned directly. - -MMIO accesses are recorded via page faults. Just before __ioremap() returns, -the mapped pages are marked as not present. Any access to the pages causes a -fault. The page fault handler calls mmiotrace to handle the fault. Mmiotrace -marks the page present, sets TF flag to achieve single stepping and exits the -fault handler. The instruction that faulted is executed and debug trap is -entered. Here mmiotrace again marks the page as not present. The instruction -is decoded to get the type of operation (read/write), data width and the value -read or written. These are stored to the trace log. - -Setting the page present in the page fault handler has a race condition on SMP -machines. During the single stepping other CPUs may run freely on that page -and events can be missed without a notice. Re-enabling other CPUs during -tracing is discouraged. - - -Trace Log Format ----------------- - -The raw log is text and easily filtered with e.g. grep and awk. One record is -one line in the log. A record starts with a keyword, followed by keyword -dependant arguments. Arguments are separated by a space, or continue until the -end of line. The format for version 20070824 is as follows: - -Explanation Keyword Space separated arguments ---------------------------------------------------------------------------- - -read event R width, timestamp, map id, physical, value, PC, PID -write event W width, timestamp, map id, physical, value, PC, PID -ioremap event MAP timestamp, map id, physical, virtual, length, PC, PID -iounmap event UNMAP timestamp, map id, PC, PID -marker MARK timestamp, text -version VERSION the string "20070824" -info for reader LSPCI one line from lspci -v -PCI address map PCIDEV space separated /proc/bus/pci/devices data -unk. opcode UNKNOWN timestamp, map id, physical, data, PC, PID - -Timestamp is in seconds with decimals.

Introduction -=============== - -kmemtrace helps kernel developers figure out two things: -1) how different allocators (SLAB, SLUB etc.) perform -2) how kernel code allocates memory and how much - -To do this, we trace every allocation and export information to the userspace -through the relay interface. We export things such as the number of requested -bytes, the number of bytes actually allocated (i.e. including internal -fragmentation), whether this is a slab allocation or a plain kmalloc() and so -on. - -The actual analysis is performed by a userspace tool (see section III for -details on where to get it from). It logs the data exported by the kernel, -processes it and (as of writing this) can provide the following information: -- the total amount of memory allocated and fragmentation per call-site -- the amount of memory allocated and fragmentation per allocation -- total memory allocated and fragmentation in the collected dataset -- number of cross-CPU allocation and frees (makes sense in NUMA environments) - -Moreover, it can potentially find inconsistent and erroneous behavior in -kernel code, such as using slab free functions on kmalloc'ed memory or -allocating less memory than requested (but not truly failed allocations). - -kmemtrace also makes provisions for tracing on some arch and analysing the -data on another. - -II. Design and goals -==================== - -kmemtrace was designed to handle rather large amounts of data. Thus, it uses -the relay interface to export whatever is logged to userspace, which then -stores it. Analysis and reporting is done asynchronously, that is, after the -data is collected and stored. By design, it allows one to log and analyse -on different machines and different arches. - -As of writing this, the ABI is not considered stable, though it might not -change much. However, no guarantees are made about compatibility yet. When -deemed stable, the ABI should still allow easy extension while maintaining -backward compatibility. This is described further in Documentation/ABI. - -Summary of design goals: - - allow logging and analysis to be done across different machines - - be fast and anticipate usage in high-load environments (*) - - be reasonably extensible - - make it possible for GNU/Linux distributions to have kmemtrace - included in their repositories - -(*) - one of the reasons Pekka Enberg's original userspace data analysis - tool's code was rewritten from Perl to C (although this is more than a - simple conversion) - - -III. Quick usage guide -====================== - -1) Get a kernel that supports kmemtrace and build it accordingly (i.e. enable -CONFIG_KMEMTRACE). - -2) Get the userspace tool and build it: -$ git-clone git://repo.or.cz/kmemtrace-user.git # current repository -$ cd kmemtrace-user/ -$ ./autogen.sh -$ ./configure -$ make - -3) Boot the kmemtrace-enabled kernel if you haven't, preferably in the -'single' runlevel (so that relay buffers don't fill up easily), and run -kmemtrace: -# '$' does not mean user, but root here. -$ mount -t debugfs none /sys/kernel/debug -$ mount -t proc none /proc -$ cd path/to/kmemtrace-user/ -$ ./kmemtraced -Wait a bit, then stop it with CTRL+C. -$ cat /sys/kernel/debug/kmemtrace/total_overruns # Check if we didn't - # overrun, should - # be zero. -$ (Optionally) [Run kmemtrace_check separately on each cpu[0-9]*.out file to - check its correctness] -$ ./kmemtrace-report - -Now you should have a nice and short summary of how the allocator performs. - -IV. FAQ and known issues -======================== - -Q: 'cat /sys/kernel/debug/kmemtrace/total_overruns' is non-zero, how do I fix -this? Should I worry? -A: If it's non-zero, this affects kmemtrace's accuracy, depending on how -large the number is. You can fix it by supplying a higher -'kmemtrace.subbufs=N' kernel parameter. ---- - -Q: kmemtrace_check reports errors, how do I fix this? Should I worry? -A: This is a bug and should be reported. It can occur for a variety of -reasons: - - possible bugs in relay code - - possible misuse of relay by kmemtrace - - timestamps being collected unorderly -Or you may fix it yourself and send us a patch. ---- - -Q: kmemtrace_report shows many errors, how do I fix this? Should I worry? -A: This is a known issue and I'm working on it. These might be true errors -in kernel code, which may have inconsistent behavior (e.g. allocating memory -with kmem_cache_alloc() and freeing it with kfree()). Pekka Enberg pointed -out this behavior may work with SLAB, but may fail with other allocators. - -It may also be due to lack of tracing in some unusual allocator functions. - -We don't want bug reports regarding this issue yet. ---- - -V.

Some applications which perform job-scheduling functions consult the load average when making decisions. If a cgroup is frozen, the load average does not provide a useful measure of the system's utilization to such applications. This is especially inconvenient if the job scheduler employs the cgroup freezer as a mechanism for preempting low priority jobs. Contrast this with using SIGSTOP for the same purpose: the stopped tasks do not count toward system load. Change task_contributes_to_load() to return false if the task is frozen. This results in /proc/loadavg behavior that better meets users' expectations.

Especially the cpu_relax() loop in mutex_spin_on_owner might hurt if the mutex holding cpu has been scheduled away by the hypervisor. We would end up in a cpu_relax() loop when there is no chance that the state of the mutex changes until the target cpu has been scheduled again by the hypervisor. For that reason we should change the default behaviour to no-spin on s390. We do have an instruction which allows to yield the current cpu in favour of a different target cpu. Also we have an instruction which allows us to figure out if the target cpu is physically backed. However we need to do some performance tests until we can come up with a solution that will do the right thing on s390.

Due to function inlining this may be seen as an oops in down_write() as called from request_key_and_link(). This situation crops up during boot, where request_key() is called from within the kernel (such as in CIFS mounts) where nobody is actually logged in, and so PAM has not had a chance to create a session keyring and user keyrings to act as the fallback. To fix this, make construct_alloc_key() not attempt to cache a key if there is no fallback key if no destination keyring is given specifically.

This patch adds more strict buffer position checks based on jiffies when internal hw_ptr is updated. Enable xrun_debug to see mangling of wrong positions. As a side effect, the hw_ptr interrupt update routine might do slightly better job when many interrupts are lost.

That is if one CPU is changing the identity map memtype to _WC, no other CPU at the time of this change should not have a TLB for this page that carries a WB attribute. SDM suggests to make the page not present. But for that we will have to handle any page faults that can potentially happen due to these pages being not present. Other way to deal with this without having any WB mapping is to change the page first to UC and then to WC. This ensures that we meet the SDM requirement of no cacheable alais to WC page. This also has same or lower overhead than marking the page not present and making it present later.

This permits the symlinks include/asm/proc and include/asm/unit to be dispensed with. This does, however, require that #include be converted to #include and similarly for asm/unit -> unit.

We previously needed that so we could install either a fixed event handler or a notify handler, but the Linux/ACPI code now handles that for us, so we don't need to worry about it. Note that this removes the FF/CM annotation from the "info" files in /proc. For example, /proc/acpi/button/PWRF/info: -type: Power Button (FF) +type: Power Button I don't think there's anything meaningful user-space can do by knowing whether a button is a control method or a fixed hardware button, so nobody should be looking at the FF/CM.

Any change to that target will cause an initramfs rebuild, even if the symlink points to something outside of the initramfs directory. If the target happens to be /tmp, the rebuild occurs for each kernel build, since gen_initramfs_list uses mktemp... Proposed way to fix it is to omit symbolic links from generated dependencies, but this has a small drawback: changing perm/owner on a symlink will go unnoticed.

We already saw one case of a similar issue in the ACPI battery code, where the kernel itself expected the module to be all done, and unmapped the init memory - but the async device discovery was still running. That got hacked around by just removing the "__init" (see commit 5d38258ec026921a7b266f4047ebeaa75db358e5 "ACPI battery: fix async boot oops"), but the real fix is to just make the module loading wait for all async work to be completed. It will slow down module loading, but since common devices should be built in anyway, and since the bug is really annoying and hard to handle from user space (and caused several S3 resume regressions), the simple fix to wait is the right one. This fixes at least http://bugzilla.kernel.org/show_bug.cgi?id=13063 but probably a few other bugzilla entries too (12936, for example), and is confirmed to fix Rafael's storage driver breakage after resume bug report (no bugzilla entry). We should also be able to now revert that ACPI battery fix. Reported-and-tested-by: Rafael J.

But when such taint happens, a developer might still be working on the kernel, expecting that lockdep is still enabled. But a taint disables lockdep without ever warning about it. Such a kernel behaviour doesn't really help for kernel development. This patch adds this missing warning. Since the taint is done most of the time after the main message that explain the real source issue, it seems safe to warn about it inside add_taint() so that it appears at last, without hurting the main information. v2: Use a generic helper to disable lockdep instead of an open coded xchg().

This might be convenient to ignore bad locking issues which sources come from outside the kernel tree. Nevertheless, it might be a frustrating experience for the staging developers or those who experience a warning but are focused on another things that require lockdep. The v2 of this patch simply don't disable anymore lockdep in case of TAINT_CRAP and TAINT_WARN events.

This fixes the problem by adding a function to sufile which does the operation adjusting the counters, and by letting the recovery function use it.

Instead of just setting the array entry to zero, we now copy any additional entries down one slot, putting the zero entry at the end. With this change we can now have all the loops that walk the array stop when they hit a zero since there will be no addresses after it.

Hallyn" Date: Mon, 13 Apr 2009 09:56:14 -0500 Subject: add some long-missing capabilities to fs_mask When POSIX capabilities were introduced during the 2.1 Linux cycle, the fs mask, which represents the capabilities which having fsuid==0 is supposed to grant, did not include CAP_MKNOD and CAP_LINUX_IMMUTABLE. However, before capabilities the privilege to call these did in fact depend upon fsuid==0. This patch introduces those capabilities into the fsmask, restoring the old behavior. See the thread starting at http://lkml.org/lkml/2009/3/11/157 for reference. Note that if this fix is deemed valid, then earlier kernel versions (2.4 and 2.2) ought to be fixed too.

For such PHY configurations using shared PHY interrupt phy_interrupt() handler will also schedule a work for PHY port which didn't cause an interrupt. This patch adds a possibility for PHY drivers to provide did_interrupt() function which reports if the PHY (or a PHY port in a multi-PHY device) generated an interrupt. This function is called in phy_change() as phy_change() shouldn't proceed if it is invoked for a PHY which didn't cause an interrupt.

The complexity of the driver is mainly due to handling the substantial delays between requesting a reading and the device pulling the data line low to indicate that the data is available. This is handled by an interrupt that is disabled under all other conditions. I wasn't terribly clear on the best way to handle this, so comments on that aspect would be particularly welcome! Interpretation of the temperature depends on knowing the supply voltage. If configured in a board config as a regulator consumer this is obtained from the regulator subsystem. If not it should be provided in the platform data. I've placed this driver in the hwmon subsystem as it is definitely a device that may be used for hardware monitoring and with it's relatively slow response times (up to 120 millisecs to get a reading) a caching strategy certainly seems to make sense!

The -memory controller tracks the movement of pages to and from the unevictable list. When a memory control group comes under memory pressure, the controller will not attempt to reclaim pages on the unevictable list. This has a couple of -effects. Because the pages are "hidden" from reclaim on the unevictable list, -the reclaim process can be more efficient, dealing only with pages that have -a chance of being reclaimed. On the other hand, if too many of the pages -charged to the control group are unevictable, the evictable portion of the -working set of the tasks in the control group may not fit into the available -memory. This can cause the control group to thrash or to oom-kill tasks. - - -Unevictable LRU: Detecting Unevictable Pages - -The function page_evictable(page, vma) in vmscan.c determines whether a -page is evictable or not. For ramfs pages and pages in SHM_LOCKed regions, -page_evictable() tests a new address space flag, AS_UNEVICTABLE, in the page's -address space using a wrapper function. Wrapper functions are used to set, -clear and test the flag to reduce the requirement for #ifdef's throughout the -source code. AS_UNEVICTABLE is set on ramfs inode/mapping when it is created. -This flag remains for the life of the inode. - -For shared memory regions, AS_UNEVICTABLE is set when an application -successfully SHM_LOCKs the region and is removed when the region is -SHM_UNLOCKed. Note that shmctl(SHM_LOCK, ...) does not populate the page -tables for the region as does, for example, mlock(). So, we make no special -effort to push any pages in the SHM_LOCKed region to the unevictable list. -Vmscan will do this when/if it encounters the pages during reclaim. On -SHM_UNLOCK, shmctl() scans the pages in the region and "rescues" them from the -unevictable list if no other condition keeps them unevictable. If a SHM_LOCKed -region is destroyed, the pages are also "rescued" from the unevictable list in -the process of freeing them. - -page_evictable() detects mlock()ed pages by testing an additional page flag, -PG_mlocked via the PageMlocked() wrapper.

This can cause + the control group to thrash or to OOM-kill tasks. + + +MARKING ADDRESS SPACES UNEVICTABLE +---------------------------------- + +For facilities such as ramfs none of the pages attached to the address space +may be evicted. To prevent eviction of any such pages, the AS_UNEVICTABLE +address space flag is provided, and this can be manipulated by a filesystem +using a number of wrapper functions: + + (*) void mapping_set_unevictable(struct address_space *mapping); + + Mark the address space as being completely unevictable. + + (*) void mapping_clear_unevictable(struct address_space *mapping); + + Mark the address space as being evictable. + + (*) int mapping_unevictable(struct address_space *mapping); + + Query the address space, and return true if it is completely + unevictable. + +These are currently used in two places in the kernel: + + (1) By ramfs to mark the address spaces of its inodes when they are created, + and this mark remains for the life of the inode. + + (2) By SYSV SHM to mark SHM_LOCK'd address spaces until SHM_UNLOCK is called. + + Note that SHM_LOCK is not required to page in the locked pages if they're + swapped out; the application must touch the pages manually if it wants to + ensure they're in memory. + + +DETECTING UNEVICTABLE PAGES +--------------------------- + +The function page_evictable() in vmscan.c determines whether a page is +evictable or not using the query function outlined above [see section "Marking +address spaces unevictable"] to check the AS_UNEVICTABLE flag. + +For address spaces that are so marked after being populated (as SHM regions +might be), the lock action (eg: SHM_LOCK) can be lazy, and need not populate +the page tables for the region as does, for example, mlock(), nor need it make +any special effort to push any pages in the SHM_LOCK'd area to the unevictable +list. Instead, vmscan will do this if and when it encounters the pages during +a reclamation scan. + +On an unlock action (such as SHM_UNLOCK), the unlocker (eg: shmctl()) must scan +the pages in the region and "rescue" them from the unevictable list if no other +condition is keeping them unevictable. If an unevictable region is destroyed, +the pages are also "rescued" from the unevictable list in the process of +freeing them. + +page_evictable() also checks for mlocked pages by testing an additional page +flag, PG_mlocked (as wrapped by PageMlocked()). If the page is NOT mlocked, +and a non-NULL VMA is supplied, page_evictable() will check whether the VMA is VM_LOCKED via is_mlocked_vma(). is_mlocked_vma() will SetPageMlocked() and update the appropriate statistics if the vma is VM_LOCKED.

Since that patch we have a window after exit_ptrace() drops tasklist and before forget_original_parent() takes it again. In this window the child can do ptrace(PTRACE_TRACEME) and nobody can untrace this child after that. Change ptrace_traceme() to not attach to the exiting ->real_parent. We don't report the error in this case, we pretend we attach right before ->real_parent calls exit_ptrace() which should untrace us anyway.

It seems like the logic required for XIP on nommu, i.e. ftruncate to reported cpio header file size (body_len) is broken for hardlinks, which have a reported size of 0, and the truncate thus nukes the contents of the file (in my case busybox), making boot impossible and ending with runaway loop modprobe binfmt-0000 - and of course 0000 is not a valid binary format. My fix is to only call ftruncate if size is non-zero which fixes things for me, but I'm not certain whether this will break XIP for those files on nommu systems, although I would guess not.

For that, we have "tsk->active_mm", + which shows what the currently active address space is. + + The rule is that for a process with a real address space (ie tsk->mm is + non-NULL) the active_mm obviously always has to be the same as the real + one. + + For a anonymous process, tsk->mm == NULL, and tsk->active_mm is the + "borrowed" mm while the anonymous process is running. When the + anonymous process gets scheduled away, the borrowed address space is + returned and cleared. + +To support all that, the "struct mm_struct" now has two counters: a +"mm_users" counter that is how many "real address space users" there are, +and a "mm_count" counter that is the number of "lazy" users (ie anonymous +users) plus one if there are any real users. + +Usually there is at least one real user, but it could be that the real +user exited on another CPU while a lazy user was still active, so you do +actually get cases where you have a address space that is _only_ used by +lazy users. That is often a short-lived state, because once that thread +gets scheduled away in favour of a real thread, the "zombie" mm gets +released because "mm_users" becomes zero. + +Also, a new rule is that _nobody_ ever has "init_mm" as a real MM any +more.

Hugh: reverted its unsigned long longs in shmem_truncate_range() and shmem_getpage(): the pagecache index cannot be more than an unsigned long, so the divisions by zero occurred in unreached code.

Before we are going to allocate new blocks, we have to recheck the block chain we have obtained so far without holding truncate_mutex.

The sync_completed file reports how much of a resync (or recovery or reshape) has been completed. However due to the possibility of out-of-order completion of writes, it is not certain to be accurate. We have an internal value - mddev->curr_resync_completed - which is an accurate value (though it might not always be quite so uptodate). So: - make curr_resync_completed be uptodate a little more often, particularly when raid5 reshape updates status in the metadata - report curr_resync_completed in the sysfs file - allow poll/select to report all updates to md/sync_completed. This makes sync_completed completed usable by any external metadata handler that wants to record this status information in its metadata.

McKenney" Date: Mon, 13 Apr 2009 21:31:16 -0700 Subject: rcu: Make hierarchical RCU less IPI-happy This patch fixes a hierarchical-RCU performance bug located by Anton Blanchard. The problem stems from a misguided attempt to provide a work-around for jiffies-counter failure. This work-around uses a per-CPU n_rcu_pending counter, which is incremented on each call to rcu_pending(), which in turn is called from each scheduling-clock interrupt. Each CPU then treats this counter as a surrogate for the jiffies counter, so that if the jiffies counter fails to advance, the per-CPU n_rcu_pending counter will cause RCU to invoke force_quiescent_state(), which in turn will (among other things) send resched IPIs to CPUs that have thus far failed to pass through an RCU quiescent state. Unfortunately, each CPU resets only its own counter after sending a batch of IPIs. This means that the other CPUs will also (needlessly) send -another- round of IPIs, for a full N-squared set of IPIs in the worst case every three scheduler-clock ticks until the grace period finally ends. It is not reasonable for a given CPU to reset each and every n_rcu_pending for all the other CPUs, so this patch instead simply disables the jiffies-counter "training wheels", thus eliminating the excessive IPIs. Note that the jiffies-counter IPIs do not have this problem due to the fact that the jiffies counter is global, so that the CPU sending the IPIs can easily reset things, thus preventing the other CPUs from sending redundant IPIs. Note also that the n_rcu_pending counter remains, as it will continue to be used for tracing. It may also see use to update the jiffies counter, should an appropriate kick-the-jiffies-counter API appear. Located-by: Anton Blanchard Tested-by: Anton Blanchard Signed-off-by: Paul E.

[...] > > The only reason we migrate MSIs in interrupt context today is that there > wasn't infrastructure for support migration both in interrupt context > and outside of it. Yes. The idea here was to force the MSI migration to happen in process context. One of the patches in the series did disable_irq(dev->irq); irq_set_affinity(dev->irq, cpumask_of(dev->cpu)); enable_irq(dev->irq); with the above patch adding irq/manage code check for interrupt disabled and moving the interrupt in process context. IIRC, there was no IRQ_MOVE_PCNTXT when we were developing this HPET code and we ended up having this ugly hack. IRQ_MOVE_PCNTXT was there when we eventually submitted the patch upstream. But, looks like I did a blind rebasing instead of using IRQ_MOVE_PCNTXT in hpet MSI code. Below patch fixes this. i.e., revert commit 932775a4ab622e3c99bd59f14cc and add PCNTXT to HPET MSI setup. Also removes copying of desc->affinity in generic code as set_affinity routines are doing it internally. Reported-by: "Eric W. Biederman" Signed-off-by: Venkatesh Pallipadi Acked-by: "Eric W.

The dasd driver can automatically online detected dasds, which especially important for finding the root device. Currently, it will wait for each online operation to finish individually, which may take long if many dasds need to be onlined. When using the new async framework, these onlining operations can run in parallel and presence of the root device is ensured by the fact that prepare_namespace() waits for all async threads to finish.

If the kernel paramert possible_cpus= is passed the cpu_possible_map is supposed to have x bits set. However the current code just sets the x bits without clearing the NR_CPUS bits that were already set. So we end up with an unchanged map that has all bits set. To fix this just clear the map before setting any new bits. This broke with def6cfb70bab83c0094bc0cedd27c4eda563043e "[S390] cpumask: Use accessors code."

The Oops is triggered by the power-up sequence during the free due to the pincfg restoration. Since the power-up sequence is involved with the unsol handling, the jack reporting may be issued during that. The Oops occurs with this jack reporting because the jack instances have been already released but the codec doesn't do the proper book-keeping.

The distribution bitmap had been constructed assuming 0 as the base node number. That construct would not have allowed a total system of greater than 256 nodes. It also corrects an error that occurred when the first blade's nasid was not zero. That nasid was stored as the base node. The base node number gets added by hardware to the node numbers implied in the distribution bitmap, resulting in invalid target nasids. Tested on the UV hardware simulator.

These drivers rely on error_state to determine if they can access the device in their slot_reset callback, thus error_state needs to be set to pci_io_channel_normal in eeh_report_reset(). Below is a detailed explanation (courtesy of Richard Lary) as to why this is necessary. Background: PCI MMIO or DMA accesses to a frozen slot generate additional EEH errors. If the number of additional EEH errors exceeds EEH_MAX_FAILS the adapter will be shutdown. To avoid triggering excessive EEH errors and an undesirable adapter shutdown, some drivers use the pci_channel_offline(dev) wrapper function to return a Boolean value based on the value of pci_dev->error_state to determine if PCI MMIO or DMA accesses are safe. If the wrapper returns TRUE, drivers must not make PCI MMIO or DMA access to their hardware. The pci_dev structure member error_state reflects one of three values, 1) pci_channel_io_normal, 2) pci_channel_io_frozen, 3) pci_channel_io_perm_failure. Function pci_channel_offline(dev) returns TRUE if error_state is pci_channel_io_frozen or pci_channel_io_perm_failure. The EEH driver sets pci_dev->error_state to pci_channel_io_frozen at the point where the PCI slot is frozen. Currently, the EEH driver restores dev->error_state to pci_channel_io_normal in eeh_report_resume() before calling the driver's resume callback. However, when the EEH driver calls the driver's slot_reset callback() from eeh_report_reset(), it incorrectly indicates the error state is still pci_channel_io_frozen. Waiting until eeh_report_resume() to restore dev->error_state to pci_channel_io_normal is too late for Emulex and QLogic FC drivers and any other drivers which are designed to use common code paths in these two cases: i) those called after the driver's slot_reset callback() and ii) those called after the PCI slot is frozen but before the driver's slot_reset callback is called. Case i) all driver paths executed to reinitialize the hardware after a reset and case ii) all code paths executed by driver kernel threads that run asynchronous to the main driver thread, such as interrupt handlers and worker threads to process driver work queues. Emulex and QLogic FC drivers are designed with common code paths which require that pci_channel_offline(dev) reflect the true state of the hardware. The state transitions that the hardware takes from Normal Operations to Slot Frozen to Reset to Normal Operations are documented in the Power Architecture™ Platform Requirements+ (PAPR+) in Table 75. PE State Control. PAPR defines the following 3 states: 0 -- Not reset, Not EEH stopped, MMIO load/store allowed, DMA allowed (Normal Operations) 1 -- Reset, Not EEH stopped, MMIO load/store disabled, DMA disabled 2 -- Not reset, EEH stopped, MMIO load/store disabled, DMA disabled (Slot Frozen) An EEH error places the slot in state 2 (Frozen) and the adapter driver is notified that an EEH error was detected. If the adapter driver returns PCI_ERS_RESULT_NEED_RESET, the EEH driver calls eeh_reset_device() to place the slot into state 1 (Reset) and eeh_reset_device completes by placing the slot into State 0 (Normal Operations). Upon return from eeh_reset_device(), the EEH driver calls eeh_report_reset, which then calls the adapter's slot_reset callback. At the time the adapter's slot_reset callback is called, the true state of the hardware is Normal Operations and should be accurately reflected by setting dev->error_state to pci_channel_io_normal. The current implementation of EEH driver does not do so and requires this change to correct this deficiency.

Device will be plugged. + * SWRITE Like WRITE, but a special case for ll_rw_block() that + * tells it to lock the buffer first. Normally a buffer + * must be locked before doing IO. + * WRITE_SYNC_PLUG Synchronous write. Identical to WRITE, but passes down + * the hint that someone will be waiting on this IO + * shortly. The device must still be unplugged explicitly, + * WRITE_SYNC_PLUG does not do this as we could be + * submitting more writes before we actually wait on any + * of them. + * WRITE_SYNC Like WRITE_SYNC_PLUG, but also unplugs the device + * immediately after submission. The write equivalent + * of READ_SYNC. + * WRITE_ODIRECT Special case write for O_DIRECT only. + * SWRITE_SYNC + * SWRITE_SYNC_PLUG Like WRITE_SYNC/WRITE_SYNC_PLUG, but locks the buffer. + * See SWRITE. + * WRITE_BARRIER Like WRITE, but tells the block layer that all + * previously submitted writes must be safely on storage + * before this one is started.

The test case is: tiotest -k0 -k1 -k3 -f 80 -t 32 which starts 32 threads each reading a 80MB file. Twiddle the kick queue logic so that we do start IO immediately, if it appears to be a fully merged request. We can't really detect that, so just check if the request is bigger than a page or not. The assumption is that since single bio issues will first queue a single request with just one page attached and then later do merges on that, if we already have more than a page worth of data in the request, then the request is most likely good to go. Verified that this doesn't cause a regression with the test case that commit b029195dda0129b427c6e579a3bb3ae752da3a93 was fixing. It does not, we still see maximum sized requests for the queue-then-merge cases.

With PREEMPT kernel ZAP_BLOCK_SIZE is 8 pages, so there is a noticeable performance penalty when unmapping a large VMA and the system is spending its time in flush_tlb_range(). The problem is that tlb_end_vma() is always flushing the full VMA range. The subrange that needs to be flushed can be calculated by tlb_remove_tlb_entry(). This approach was suggested by Hugh Dickins, and is also used by other arches. The speed increase is roughly 3x for 8M mappings and for larger mappings even more.

Instead allow the close process to issue a request, getting better aggregate bandwidth. The anticipatory scheduler has similar checks, noop and deadline do not need it since they don't care about process <-> io mappings. The code for CFQ is a little more involved though, since we split request queues into per-process contexts. This fixes a performance problem with eg dump(8), since it uses several processes in some silly attempt to speed IO up. Even if dump(8) isn't really a valid case (it should be fixed by using CLONE_IO), there are other cases where we see close processes and where idling ends up hurting performance.

My bad. 'smp_call_function_many()' has two "features" (aka "documented bugs"): (a) it needs to be called with preemption disabled, because it uses smp_processor_id() without guarding the CPU lookup with 'get_cpu()' and 'put_cpu()' like the 'single' variant does. (b) even if the current CPU is part of the CPU mask, it won't do the call on that CPU. Still, we're better off trying to use 'smp_call_function_many()' than looping over CPU's, since it at least in theory allows us to use a broadcast IPI and do it all in parallel. So let's just work around the silly semantic bugs in that function.

The problem is that MN10300's implementation of BUG() invokes system call 15 which doesn't return - but there's no way to tell the compiler that and also emit the bug table element with the correct file and line data. So instead, we make the do...while wrapper in _debug_bug_trap() an endless loop from which there's no escape. Also, while we're at it, (1) get rid of _debug_bug_trap() and just implement directly as BUG(), and (2) make the implementation of BUG() contingent on CONFIG_BUG=y.

This results in dropping almost all frames from reorder buffer when security is enabled by doing double decryption (first in hw, second in sw because of wrong rx status).

This is used for protection against buggy hardware/firmware that raises RX interrupts without doing an actual DMA transfer. This mechanism protects against rare "bad packets" (due to uninitialized skb data) and rare kernel crashes due to uninitialized RX headers. The poison is selected to not match on valid frames and to be cheap for checking. The poison check mechanism _might_ trigger incorrectly, if we are voluntarily receiving frames with bad PLCP headers. However, this is nonfatal, because the chance of such a match is basically zero and in case it happens it just results in dropping the packet. Bad-PLCP RX defaults to off, and you should leave it off unless you want to listen to the latest news broadcasted by your microwave oven. This patch also moves the initialization of the RX-header "length" field in front of the mapping of the DMA buffer. The CPU should not touch the buffer after we mapped it.

Introduce a IP_NAT_RANGE_PERSISTENT option that controls whether the destination address is taken into account for selecting addresses. http://bugzilla.kernel.org/show_bug.cgi?id=12954 Signed-off-by: Patrick McHardy --- include/net/netfilter/nf_nat.h | 1 + net/ipv4/netfilter/nf_nat_core.c | 3 ++- 2 files changed, 3 insertions(+), 1 deletion(-) diff --git a/include/net/netfilter/nf_nat.h b/include/net/netfilter/nf_nat.h index 9dc1039ff78..8df0b7f7fc6 100644 --- a/include/net/netfilter/nf_nat.h +++ b/include/net/netfilter/nf_nat.h @@ -18,6 +18,7 @@ enum nf_nat_manip_type #define IP_NAT_RANGE_MAP_IPS 1 #define IP_NAT_RANGE_PROTO_SPECIFIED 2 #define IP_NAT_RANGE_PROTO_RANDOM 4 +#define IP_NAT_RANGE_PERSISTENT 8 /* NAT sequence number modifications */ struct nf_nat_seq { diff --git a/net/ipv4/netfilter/nf_nat_core.c b/net/ipv4/netfilter/nf_nat_core.c index fe65187810f..3229e0a81ba 100644 --- a/net/ipv4/netfilter/nf_nat_core.c +++ b/net/ipv4/netfilter/nf_nat_core.c @@ -211,7 +211,8 @@ find_best_ips_proto(struct nf_conntrack_tuple *tuple, minip = ntohl(range->min_ip); maxip = ntohl(range->max_ip); j = jhash_2words((__force u32)tuple->src.u3.ip, - (__force u32)tuple->dst.u3.ip, 0); + range->flags & IP_NAT_RANGE_PERSISTENT ? + (__force u32)tuple->dst.u3.ip : 0, 0); j = ((u64)j * (maxip - minip + 1)) >> 32; *var_ipp = htonl(minip + j); } -- cgit v1.2.3 From 5e075cb5cee4faecc82e2b8a04e640176629976e Mon Sep 17 00:00:00 2001 From: Hartley Sweeten Date: Thu, 16 Apr 2009 17:56:10 +0100 Subject: [ARM] 5454/1: ep93xx_eth: fix sparse warnings Fix 50+ sparse warnings in the ep93xx ethernet driver. warning: incorrect type in argument 1 (different address spaces) Signed-off-by: H Hartley Sweeten Signed-off-by: Russell King --- drivers/net/arm/ep93xx_eth.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/net/arm/ep93xx_eth.c b/drivers/net/arm/ep93xx_eth.c index cc7708775da..c140c9bb767 100644 --- a/drivers/net/arm/ep93xx_eth.c +++ b/drivers/net/arm/ep93xx_eth.c @@ -153,7 +153,7 @@ struct ep93xx_descs struct ep93xx_priv { struct resource *res; - void *base_addr; + void __iomem *base_addr; int irq; struct ep93xx_descs *descs; -- cgit v1.2.3 From 4ea3c51d5bd3bb4eea7d7d3a1f80d1a48c2a6f92 Mon Sep 17 00:00:00 2001 From: Cliff Wickman Date: Thu, 16 Apr 2009 07:53:09 -0500 Subject: x86: UV BAU distribution and payload MMRs This patch correctly sets BAU memory mapped registers to point to the sending activation descriptor table and target payload table. The "Broadcast Assist Unit" is used for TLB shootdown in UV. The memory mapped registers that point to sending and receiving memory structures contain node numbers. In one case the __pa() function did not provide the node id of memory on blade zero in configurations where that id is nonzero. In another case, it was assumed that memory was allocated on the local node. That assumption is not true in a configuration in which the node has no memory. Tested on the UV hardware simulator.

This reverts commit f520360d93cdc37de5d972dac4bf3bdef6a7f6a7. Tetsuo Handa, running a kernel with CONFIG_DEBUG_PAGEALLOC=y and CONFIG_UEVENT_HELPER_PATH=/sbin/hotplug, has been hitting RCU detected CPU stalls: it's been spinning in the loop where do_execve() counts up the args (but why wasn't fixup_exception working? dunno). The recent change, switching kobject_uevent_env() from UMH_WAIT_EXEC to UMH_NO_WAIT, is broken: the exec uses args on the local stack here, and an env which is kfreed as soon as call_usermodehelper() returns. It very much needs to wait for the exec to be done. An alternative would be to keep the UMH_NO_WAIT, and complicate the code to allocate and free these resources correctly? but no, as GregKH pointed out when making the commit, CONFIG_UEVENT_HELPER_PATH="" is a much better optimization - though some distros are still saying /sbin/hotplug in their .config, yet with no such binary in their initrd or their root.

Yes, a UMH_NO_WAIT or UMH_WAIT_PROC call_usermodehelper() spawns an mm-less kernel thread to do the exec. And in any case, that vm_enough_memory check when growing stack ought to be done on the target mm, not on the execer's mm (though apart from the warning, it only makes a slight tweak to OVERCOMMIT_NEVER behaviour).

This patch just removes the track/untrack of vm_insert_pfn. That means we will be in same state as 2.6.28, with respect to these APIs.

So as long as sysfs attributes cannot commit suicide directly and we are stuck with this callback mechanism, put the sysfs callbacks on their own workqueue instead of the global one. This has the side benefit that if a suicidal sysfs attribute kicks off a long chain of ->remove callbacks, we no longer induce a long delay on the global queue. This also fixes a missing module_put in the error path introduced by sysfs-only-allow-one-scheduled-removal-callback-per-kobj.patch. We never destroy the workqueue, but I'm not sure that's a problem.

Platform drivers are great for embedded platforms because we can separate driver configuration from the actual driver. So base addresses, interrupts and other configuration can be kept with the processor or board code, and the platform driver can be reused by many different platforms. For early devices we have nothing today. For instance, to configure early timers and early serial ports we cannot use platform devices. This because the setup order during boot. Timers are needed before the platform driver core code is available. The same goes for early printk support. Early in this case means before initcalls. These early drivers today have their configuration either hard coded or they receive it using some special configuration method. This is working quite well, but if we want to support both regular kernel modules and early devices then we need to have two ways of configuring the same driver. A single way would be better. The early platform driver patch is basically a set of functions that allow drivers to register themselves and architecture code to locate them and probe. Registration happens through early_param(). The time for the probe is decided by the architecture code. See Documentation/driver-model/platform.txt for more details.

There are circumstances when a user-space process might need to "oversee" a resync/reshape process. For example when doing an in-place reshape of a raid5, it is prudent to take a backup of each section before reshaping it as this is the only way to provide safety against an unplanned shutdown (i.e. crash/power failure). The sync_max sysfs value can be used to stop the resync from advancing beyond a particular point. So user-space can: suspend IO to the first section and back it up set 'sync_max' to the end of the section wait for 'sync_completed' to reach that point resume IO on the first section and move on to the next section. However this process requires the kernel and user-space to run in lock-step which could introduce unnecessary delays. It would be better if a 'double buffered' approach could be used with userspace and kernel space working on different sections with the 'next' section always ready when the 'current' section is finished. One problem with implementing this is that sync_completed is only guaranteed to be updated when the sync process reaches sync_max. (it is updated on a time basis at other times, but it is hard to rely on that). This defeats some of the double buffering. With this patch, sync_completed (and reshape_position) get updated as the current position approaches sync_max, so there is room for userspace to advance sync_max early without losing updates. To be precise, sync_completed is updated when the current sync position reaches half way between the current value of sync_completed and the value of sync_max. This will usually be a good time for user space to update sync_max. If sync_max does not get updated, the updates to sync_completed (together with associated metadata updates) will occur at an exponentially increasing frequency which will get unreasonably fast (one update every page) immediately before the process hits sync_max and stops. So the update rate will be unreasonably fast only for an insignificant period of time.

The patches fixing it were both complex and fragile, according to Eric they were also doing quite dangerous things to the hardware. Instead we now have patches that solve this problem via static NUMA node mappings - not dynamic allocation and balancing. The patches are much simpler than this method but are still too large outside of the merge window, so we mark the dynamic balancer as broken for now, and queue up the new approach for v2.6.31.

There's another problem though -- if we change the mode so that the file becomes read-only then we may not be able to write data to it after a reconnect. Fix this by just going back to flushing all the dirty data on any setattr call. There are probably some cases that can be optimized out, but I'm not sure they're worthwhile and we need to consider them more carefully to make sure that we don't cause regressions if we have to reconnect before writeback occurs.

The first two didn't handle update the size correctly when writes that didn't start at the eof were done. The first patch also didn't update the size correctly when it explicitly set via truncate(). This patch adds code to track the client's current understanding of the size of the file on the server separate from the i_size, and then to use this info to semi-intelligently set the timeout for writes past the EOF. This helps prevent timeouts when trying to write large, sparse files on windows servers.

We can also get rid of the dnotify thread as well. In actuality, it never had anything to do with dir_notify anyway. All it did was unnecessarily wake up all the tasks waiting on the response queues every 15s. Previously that happened to prevent tasks from hanging indefinitely when the server went unresponsive, but we put those to sleep with proper timeouts now so there's no reason to keep this around.

This isn't the case if the string area is already word-aligned. This problem, combined with the bad buffer sizing for the serverDomain string can cause memory corruption. The bad alignment can make it so that the alignment of the characters is off. This can make them translate to characters that are greater than 2 bytes each. If this happens we can overflow the allocation. Fix this by fixing the alignment in CIFS_SessSetup instead so we can verify it against the head of the response. Also, clean up the workaround for improperly terminated strings by checking for a odd-length unicode buffers and then forcibly terminating them. Finally, resize the buffer for serverDomain. Now that we've fixed the alignment, it's probably fine, but a malicious server could overflow it. A better solution for handling these strings is still needed, but this should be a suitable bandaid.

The USB gadget speed is however often set even before the device is enumerated. It seems more sensible to only report a "link" if we're actually connected to a host that wants to talk to us.

There is an important issue with such transfers, especially on the host side: when such transfers end with a full-size packet, we must defer musb_dma_completion() calls until the FIFO empties. Else we report URB completions too soon, and may clobber data in the FIFO fifo when writing the next packet (losing data). The Inventra DMA support uses DMA mode 1, but it ignores that issue. The CPPI DMA support uses mode 0, but doesn't handle its TXPKTRDY interrupts quite right either; it can get stale "packet ready" interrupts, and report transfer completion too early using slightly different code paths, also losing data. So I'm solving it in a generic way -- by adding a sort of the "interrupt filter" into musb_host_tx(), catching these cases where a DMA completion IRQ doesn't suffice and removing some needlessly controller-specific logic. When a TXDMA interrupt happens and DMA request mode 1 is active, that filter resets to mode 0 and defers URB completion processing until TXPKTRDY, unless the FIFO is already empty. Related filtering logic in Inventra and CPPI code gets removed.

Recent versions of the programmer's guide require DMAENAB to be cleared first, although some older ones didn't. Fix this and while at it: - In musb_gadget::txstate(), stop clearing the AUTOSET and DMAMODE bits for the CPPI case since they never get set anyway (the former bit is reserved on DaVinci); but do clear the DMAENAB bit on the DMA error path. - In musb_host::musb_ep_program(), remove the duplicate DMA controller specific code code clearing the TXCSR previous state, add the code to clear TXCSR DMA bits on the Inventra DMA error path, to replace such code (executed late) on the PIO path. - In musbhsdma::dma_channel_abort()/dma_controller_irq(), add/use the 'offset' variable to avoid MUSB_EP_OFFSET() invocations on every RXCSR/TXCSR access.

With Inventra DMA they complete, but in PIO mode. To fix: - Factor out programming of the DMA transfer from musb_ep_program() into musb_tx_dma_program(); - Reorder the code at the end of musb_host_tx() to facilitate the fallback to PIO iff DMA fails; - Handle the buffer offset consistently for both PIO and DMA modes; - Add an argument to musb_ep_program() for the same reason (it only worked correctly with non-zero offset of the first frame in PIO mode); - Set the completed isochronous frame descriptor's 'actual_length' and 'status' fields correctly in DMA mode. Also, since CPPI reportedly doesn't like sending isochronous packets in the RNDIS mode, change the criterion for this mode to be used only for multi-packet transfers. (There's no need for that mode in the single-packet case anyway.)

Fixup of Werner Cornelius patch to the ch341 USB-serial driver, which adds: - support all baudrates, not just a hard-coded set - support for controlling DTR, RTS and CTS Features still missing: - character length other than 8 bits - parity settings - break control I adapted his patch for the new usb_serial API introduced in 2.6.25-git8 by Alan Cox on 22 July 2008. Non-compliance to the new API was a reason for refusing a similar patch from Tollef Fog Heen.

So allow HCDs to provide a endpoint_reset method and call this or clear the software toggles as required (after a clear halt, set configuration etc.). usb_settoggle() and friends are then HCD internal and are moved into core/hcd.h and all device drivers call usb_reset_endpoint() instead. If the device endpoint state has been reset (with a clear halt) but the host endpoint state has not then subsequent data transfers will not complete. The device will only work again after it is reset or disconnected.

This errata affects WRITE_MULTI* commands when the device multi_count produces a DRQ block size >= 4Kbytes. We work around it here by converting such operations into ordinary PIO_WRITEs instead. Note that this might result in a PIO FUA write unavoidably being converted into a non-FUA write. In practice, any system using FUA is also going to be using DMA rather than PIO, so this shouldn't affect anyone in the real world.

The consequence of this is that the "timer" trigger would not cause the LED to blink if given default parameters. This problem exists since 2.6.26-rc1. To fix it, switch the deferred LED work handling to use the thinkpad-acpi-specific LED status (off/on/blink) directly. This also makes the code easier to read, and to extend later.

This code is a bit tricky since it is also used by the nmi handler (when lockdep is off), and we must be careful about the swapgs. We can not call kernel code after the swapgs has been performed.

Wysocki" Date: Sun, 19 Apr 2009 20:08:42 +0200 Subject: PM/Suspend: Introduce two new platform callbacks to avoid breakage Commit 900af0d973856d6feb6fc088c2d0d3fde57707d3 (PM: Change suspend code ordering) changed the ordering of suspend code in such a way that the platform .prepare() callback is now executed after the device drivers' late suspend callbacks have run. Unfortunately, this turns out to break ARM platforms that need to talk via I2C to power control devices during the .prepare() callback. For this reason introduce two new platform suspend callbacks, .prepare_late() and .wake(), that will be called just prior to disabling non-boot CPUs and right after bringing them back on line, respectively, and use them instead of .prepare() and .finish() for ACPI suspend. Make the PM core execute the .prepare() and .finish() platform suspend callbacks where they were executed previously (that is, right after calling the regular suspend methods provided by device drivers and right before executing their regular resume methods, respectively). It is not necessary to make analogous changes to the hibernation code and data structures at the moment, because they are only used by ACPI platforms. Signed-off-by: Rafael J.

Because after device_unregister function our memory is dirty, we need to do clean operation in order to re-register the device, otherwise the system will crash.

Alex Sidorenko reported: "while experimenting with 'netem' we have found some strange behaviour. It seemed that ingress delay as measured by 'ping' command shows up on some hosts but not on others. After some investigation I have found that the problem is that skbuff->tstamp field value depends on whether there are any packet sniffers enabled. That is: - if any ptype_all handler is registered, the tstamp field is as expected - if there are no ptype_all handlers, the tstamp field does not show the delay" This patch prevents unnecessary update of tstamp in dev_queue_xmit_nit() on ingress path (with act_mirred) adding a check, so minimal overhead on the fast path, but only when sniffers etc. are active. Since netem at ingress seems to logically emulate a network before a host, tstamp is zeroed to trigger the update and pretend delays are from the outside.

However, this came at the cost of moving the tun wait queue into the tun file data structure. The problem with this is that it imposes restrictions on when and where the tun device can access the wait queue since the tun file may change at any time due to detaching and reattaching. In particular, now that we need to use the wait queue on the receive path it becomes difficult to properly synchronise this with the detachment of the tun device. This patch solves the original race in a different way. Since the race is only because the underlying memory gets freed, we can prevent it simply by ensuring that we don't do that until all tun descriptors ever attached to the device (even if they have since be detached because they may still be sitting in poll) have been closed. This is done by using reference counting the attached tun file descriptors. The refcount in tun->sk has been reappropriated for this purpose since it was already being used for that, albeit from the opposite angle. Note that we no longer zero tfile->tun since tun_get will return NULL anyway after the refcount on tfile hits zero. Instead it represents whether this device has ever been attached to a device.

Since the tun device is the persistent data structure here (when requested by the user), it makes much more sense to have the wait queue live there. There is no reason to have it in tfile at all since the only time we can wait is if we have a tun attached. In fact we already have a wait queue in tun_struct, so we might as well use it.

The memory that _appears_ to be at physical address 0 is actually memory that located at a different address but has been remapped by the chipset so that it appears to be at physical address 0. When determining the UV pnode, the algorithm for determining the pnode incorrectly used the relocated physical address instead of the actual (global) address.

This patch mirrors recent changes in other filesystems and the generic code to use WRITE_SYNC when WB_SYNC_ALL is passed and to use WRITE_SYNC for other latency critical writes. Btrfs uses async worker threads for checksumming before the write is done, and then again to actually submit the bios. The bio submission code just runs a per-device list of bios that need to be sent down the pipe. This list is split into low priority and high priority lists so the WRITE_SYNC IO happens first.

But, the checksumming helper threads prevent it from being fully effective. There are two problems. First, a big queue of pending checksumming will delay the synchronous IO behind other lower priority writes. Second, the checksumming uses an ordered async work queue. The ordering makes sure that IOs are sent to the block layer in the same order they are sent to the checksumming threads. Usually this gives us less seeky IO. But, when we start mixing IO priorities, the lower priority IO can delay the higher priority IO. This patch solves both problems by adding a high priority list to the async helper threads, and a new btrfs_set_work_high_prio(), which is used to make put a new async work item onto the higher priority list. The ordering is still done on high priority IO, but all of the high priority bios are ordered separately from the low priority bios. This ordering is purely an IO optimization, it is not involved in data or metadata integrity.

But, it was doing the update after unlocking the page, which isn't legal because page->mapping can't be trusted once the page is unlocked. This lead to an oops, especially common with compression turned on. The fix here is to update the writeback index before unlocking the page.

Between clear_used_math() and the state store on to the user stack, potentially we can get a page fault for the user address and can block. Infact, while testing we were hitting the might_fault() in __clear_user() which can do a schedule(). At a later point in time, we will schedule back into this process and resume the save state (using "xsave/fxsave" instruction) which can lead to DNA fault. And as used_math was cleared before, we will reinit the FP state in the DNA fault and continue. This reinit will result in loosing the FPU state of the process. Move clear_used_math() to a point after the FPU state has been stored onto the user stack. This issue is present from a long time (even before the xsave changes and the x86 merge). But it can easily be exposed in 2.6.28.x and 2.6.29.x series because of the __clear_user() in this path, which has an explicit __cond_resched() leading to a context switch with CONFIG_PREEMPT_VOLUNTARY.

This patch fixes it by locking the directory's i_mutex again before calling the filldir functions. The original deadlocks which commit 14f7dd63 was designed to avoid are still avoided, because they were due to fs-internal locking, not i_mutex. While we're at it, fix the return type of nfsd_buffered_readdir() which should be a __be32 not an int -- it's an NFS errno, not a Linux errno. And return nfserrno(-ENOMEM) when allocation fails, not just -ENOMEM. Sparse would have caught that, if it wasn't so busy bitching about __cold__. Commit 05f4f678 ("nfsd4: don't do lookup within readdir in recovery code") introduced a similar problem with calling lookup_one_len() without i_mutex, which this patch also addresses. To fix that, it was necessary to fix the called functions so that they expect i_mutex to be held; that part was done by J. Bruce Fields.

For INIT_HCA this causes problems when had more than 2^18 are QPs configured, since the command takes more than 1 second to complete. All other commands have 60-second timeouts. This patch makes the above commands consistent with the rest of the commands (and with the chip documentation). This patch is an expansion of a patch from Arthur Kepner fixing just the INIT_HCA timeout.

Strictly speaking it was using join_transaction which would be safe, but it is better to move the transaction outside of the lock. When preallocated extents are overwritten, btrfs_mark_buffer_dirty was being called on an unlocked buffer. This was triggering an assertion and oops because the lock is supposed to be held. The bug was calling btrfs_mark_buffer_dirty on a leaf after btrfs_del_item had been run. btrfs_del_item takes care of dirtying things, so the solution is a to skip the btrfs_mark_buffer_dirty call in this case.

This was safe, because the SATA driver re-enabled it. But with commit a5bfc471 ("ahci: drop intx manipulation on msi enable"), the driver no longer does this, and so SATA support on the 8610 HPCD is broken. The original quirk function disabled INTx because it caused some other interrupt problem during early development on this board, but no one remembers any more what that problem was, and it doesn't seem to occur any more.

This is required because the CPU's window onto the PCI bus address space is considerably smaller than the CPU's full address space and non-PCI devices lie outside of the PCI window that we might want to access. Without this patch, the PCI root bus uses the platform-level bus resources, and these are then confined to the PCI window, thus making platform_device_add() reject devices outside of this window.

Revert back to using iwl3945 specific routines that map/unmap memory. - no need to "dma_syn_single_range_for_cpu" followed by pci_unmap_single, we can just call pci_unmap_single initially - only map the memory area that will be used by device. this is especially relevant to the mapping of iwl_cmd. we should not map the entire structure because the meta data at the beginning of structure contains the address to be used later for unmapping. If the address to be used for unmapping is stored in mapped data it creates a problem. - ensure that _if_ memory needs to be modified after it is mapped that we call _sync_single_for_cpu first, and then release it back to device with _sync_single_for_device - we mapped the wrong length of data for host commands, with mapped length differing with length provided to device, fix that.

Walukiewicz Date: Tue, 21 Apr 2009 16:16:48 -0700 Subject: RDMA/nes: Fix resource issues in nes_create_cq() and nes_destroy_cq() In error paths where a CQ is not created, pbl is not freeed properly.

This means that architectures that have a small data section references relative to a base register may throw up linkage errors due to too great a displacement between where the base register points and the per-CPU variable. On FRV, the .h declaration says that the variable is in the .sdata section, but the .c definition says it's actually in the .data section. The linker throws up the following errors: kernel/built-in.o: In function `release_task': kernel/exit.c:78: relocation truncated to fit: R_FRV_GPREL12 against symbol `per_cpu__process_counts' defined in .data section in kernel/built-in.o kernel/exit.c:78: relocation truncated to fit: R_FRV_GPREL12 against symbol `per_cpu__process_counts' defined in .data section in kernel/built-in.o To fix this, DECLARE_PER_CPU() should simply apply the same section attribute as does DEFINE_PER_CPU(). However, this is made slightly more complex by virtue of the fact that there are several variants on DEFINE, so these need to be matched by variants on DECLARE.

Expectations of userspace are that once this module is loaded, all the (storage) devices for which the drivers were loaded before the module load are present. Now, there are some issues with the implementation, and the async stuff got caught in the middle of this: The existing code only waits for the scsy async probing to finish, but it did not take into account at all that probing might not have begun yet. (Russell ran into this problem on his computer and the fix works for him) This patch fixes this more thoroughly than the previous "fix", which had some bad side effects (namely, for kernel code that wanted to wait for the scsi scan it would also do an async sync, which would deadlock if you did it from async context already.. there's a report about that on lkml): The patch makes the module first wait for all device driver probes, and then it will wait for the scsi parallel scan to finish.

Jianjun kong Date: Mon, 20 Apr 2009 23:48:25 +0000 Subject: 8139too: fix HW initial flow While ifconfig eth0 up kernel calls open() of 8139 driver(8139too.c). In rtl8139_hw_start() of rtl8139_open(), 8139 driver enable RX before setting up the DMA buffer address. In this interval where RX was enabled and DMA buffer address is not yet set up, any incoming broadcast packet would be send to a strange physical address: 0x003e8800 which is the default value of DMA buffer address. Unfortunately, this address is used by Linux kernel. So kernel panics. This patch fix it by setting up DMA buffer address before RX enabled and everything is fine even under broadcast packets attack.

Miller" Date: Fri, 17 Apr 2009 04:14:15 -0700 Subject: sparc: Fix bus type probing for ESP and LE devices. If there is a dummy "espdma" or "ledma" parent device above ESP scsi or LE ethernet device nodes, we have to match the bus as SBUS. Otherwise the address and size cell counts are wrong and we don't calculate the final physical device resource values correctly at all. Commit 5280267c1dddb8d413595b87dc406624bb497946 ("sparc: Fix handling of LANCE and ESP parent nodes in of_device.c") was meant to fix this problem, but that only influences the inner loop of build_device_resources(). We need this logic to also kick in at the beginning of build_device_resources() as well, when we make the first attempt to determine the device's immediate parent bus type for 'reg' property element extraction.

With this patch HPET_COUNTER is still stopped but not reset when HPET is programmed in periodic mode. This should help to avoid races when HPET is programmed in periodic mode and fixes a boot time hang that I've observed on a machine when using 1000HZ.

(That is, it was using just one clock edge, not both.) Move the table's type declaration so it's adjacent to the table, making it more clear what those numbers mean. On one system this change increased throughput by almost 4x: UDMA/66 sometimes topped 23 MB/sec (on a drive known to do much better). On another system it was around a 10% win (UDMA/66 up to 7+ MB/sec). The difference might be caused by the ratio between memory and IDE clocks. In the system with large speedup, this was exactly 2 (as a workaround for a rev 1.1 silicon bug). The other system used a more standard ratio of 1.63 (and rev 2.1 silicon) ... clock domain synch might have some issues, they're not unheard-of.

Tejun agreed that the best is to blacklist the whole chipset and after adding it, seeing the other VIA quirks disabling MSI, this very much looks like the right way.

This results in a longer symlink target than if the target value wasn't encrypted. Users were reporting these messages in their syslog: [ 45.653441] ecryptfs_parse_tag_70_packet: max_packet_size is [56]; real packet size is [51] [ 45.653444] ecryptfs_decode_and_decrypt_filename: Could not parse tag 70 packet from filename; copying through filename as-is This was due to bufsiz, one the arguments in readlink(), being used to when allocating the buffer passed to the lower inode's readlink(). That symlink target may be very large, but when decoded and decrypted, could end up being smaller than bufsize. To fix this, the buffer passed to the lower inode's readlink() will always be PATH_MAX in size when filename encryption is enabled. Any necessary truncation occurs after the decoding and decrypting.

The primary goal is to have better modeling if the hardware clocks and features with the aim of DVFS functionality. Highlights: - model PLLs and all PLL-derived clocks - model parent/child relationships of PLLs and clocks - convert to new clkdev layer - view clock frequency and refcount via /proc/davinci_clocks Special thanks to significant contributions and testing by David Brownell.

From now on, drivers should always use ioremap() instead of IO_ADDRESS(). In addition, remove the davinci_[read|write]* macros in favor of using ioremap.

Function omap_free_dma() sets the dev_id = -1 and then accesses the channel afterwards to clear it. But setting the dev_id=-1 makes the channel available for allocation again. So it is possible someone else can grab it and results are unpredictable. To avod this DMA channle is cleared first and then the dev_id = -1 is set. Thanks to McNeil, Sean for ointing out this issue.

However, since there is no 'set_wake' hook for the bank IRQs, these calls will always fail. Also, since the enable will fail on the suspend path, the disable on the resume path will trigger unbalanced enable/disable warnings. This was discovered in the suspend/resume path on OMAP3/Beagle using the gpio-keys driver which disables/re-enables GPIO IRQ wakeups in the suspend/resume path.

The main symptom is that an invalid kevent is created when the serial device is unplugged while a connection is active. Ports should be unregistered when device is disconnected, not when the parent usb_serial structure is deallocated. Each open file should hold a reference to the corresponding port structure, and the reference should be released when the file is closed. serial->disc_mutex should be acquired in serial_open(), to resolve the classic race between open and disconnect. serial_close() doesn't need to hold both serial->disc_mutex and port->mutex at the same time. Release the subdriver's module reference only after releasing all the other references, in case one of the release routines needs to invoke some code in the subdriver module. Replace a call to flush_scheduled_work() (which is prone to deadlocks) with cancel_work_sync(). Also, add a call to cancel_work_sync() in the disconnect routine. Reduce the scope of serial->disc_mutex in serial_disconnect(). The only place it really needs to protect is where the "disconnected" flag is set.

This can lead to a situation in which the first 188 bytes of a 192-byte isochronous transfer are scheduled in the same uframe as an existing interrupt transfer. The resulting schedule looks like this: uframe 0: 188-byte isoc-OUT SSPLIT, 8-byte int-IN SSPLIT uframe 1: 4-byte isoc-OUT SSPLIT The SSPLITs are intermingled, causing an error in the downstream hub's TT. If you are having problems with devices or hub ports resetting, or failed interrupt transfers, when you start using a USB audio or video (Isochronous) device, this patch may help.

A device's name may not be available after the device is unregistered, even if the device structure itself is still allocated. Since close_backing_file() prints a LUN's name for debugging, it shouldn't be called after the LUN has been unregistered. That whole area needed to be cleaned up; the backing files were getting closed in a couple of different places. The patch fixes things so that they get closed in just one place, as part of the unbind procedure, immediately before the LUN is unregistered.

To avoid this, let's move the mbus bridge register defines into a separate file and include it where needed. This affects mach-kirkwood, mach-loki, mach-mv78xx0 and mach-orion5x simultaneously as they all share code in plat-orion which relies on those defines. Some other defines have been moved to narrower scopes, or simply deleted when they had no user. This fixes compilation problem with mpt2sas on the above listed platforms.

The HPET becomes available for both clocksource and clockevents. But as of ff69f2bba67bd45514923aaedbf40fe351787c59 (acpi: fix of pmtimer overflow that make Cx states time incorrect) the HPET may be used via clocksource for idle accounting, and hpet=force on an ICH4 box hangs boot. It turns out that touching the MMIO HPET withing the ARB_DIS part of C3 will hang the hardware. The fix is to simply move the timer access outside the ARB_DIS region.

Practical choices at this point are GPTIMER1 or GPTIMER12. Both of these timers are in the WKUP powerdomain, and so are unaffected by chip power management. GPTIMER1 can use sys_clk as a source, for applications where a high-resolution timer is more important than power management. GPTIMER12 has the special property that it has the secure 32kHz oscillator as its source clock, which may be less prone to glitches than the off-chip 32kHz oscillator. But on HS devices, it may not be available for Linux use. It appears that most boards are fine with GPTIMER1, but BeagleBoard should use GPTIMER12 when using a 32KiHz timer source, due to hardware bugs in revisions B4 and below. Modify board-omap3beagle.c to use GPTIMER12. This patch originally used a Kbuild config option to select the GPTIMER, but was changed to allow this to be specified in board-*.c files, per Tony's request. Kalle Vallo found a bug in an earlier version of this patch - thanks Kalle. Tested on Beagle rev B4 ES2.1, with and without CONFIG_OMAP_32K_TIMER, and 3430SDP.

Starting with e48ec690 (block: extend queue_flag bitops), the queue_flag_* functions warn if q->queue_lock doesn't appear to be locked. In fact, q->queue_lock is NULL (though that apparently isn't otherwise a problem as the driver is using card->lock for everything). Although blk_init_queue() with take a request_fn_proc and spinlock_t*, there isn't a corresponding init helper that takes a make_request_fn. Setting queue_lock to &card->lock explicitly seems to work fine for me. The warning goes away and the device appears to behave.

Fix this by using ->org_ioprio as the prio_tree index, since that will only change for explicit IO priority settings (not for a boost). Additionally cache the rbtree root inside the cfqq, then we don't have to add code to reinsert the cfqq in the prio_tree if IO priority changes.

This patch adds a workaround for this, hardcoding the number of chipselects to one for sequioa/rainer board models and reading the actual value from the memory controller register DDR0_10 otherwise. It also fixes another error in the way ibm4xx_denali_fixup_memsize calculates memory size. When testing the DDR_REDUC bit, the polarity is backwards.

This is wrong if we race with our sub-thread which also does do_execve: Two threads T1 and T2 and another process P, all share the same ->fs. T1 starts do_execve(BAD_FILE). It calls check_unsafe_exec(), since ->fs is shared, we set LSM_UNSAFE but not ->in_exec. P exits and decrements fs->users. T2 starts do_execve(), calls check_unsafe_exec(), now ->fs is not shared, we set fs->in_exec. T1 continues, open_exec(BAD_FILE) fails, we clear ->in_exec and return to the user-space. T1 does clone(CLONE_FS /* without CLONE_THREAD */). T2 continues without LSM_UNSAFE_SHARE while ->fs is shared with another process. Change check_unsafe_exec() to return res = 1 if we set ->in_exec, and change do_execve() to clear ->in_exec depending on res. When do_execve() suceeds, it is safe to clear ->in_exec unconditionally. It can be set only if we don't share ->fs with another process, and since we already killed all sub-threads either ->in_exec == 0 or we are the only user of this ->fs. Also, we do not need fs->lock to clear fs->in_exec.

By default for every 8 data block groups, we'll allocate 1 metadata chunk, or about 12% of the disk will be allocated for metadata. This can be changed by specifying the metadata_ratio mount option. This is simply the number of data block groups that have to be allocated to force a metadata chunk allocation. By making sure we allocate metadata chunks more often, we are less likely to get into situations where the whole disk has been allocated as data block groups.

This is what actually frees up any blocks replaced by COW, and anything the old blocks pointed to. Snapshot deletion will pause when a transaction commit has started, which helps to avoid a huge amount of delayed reference count updates piling up as the transaction is trying to close. But, this pause happens after the snapshot deletion process has asked other procs on the system to throttle back a bit so that it can make progress. We don't want to throttle everyone while we're waiting for the transaction commit, it leads to deadlocks in the user transaction ioctls used by Ceph and makes things slower in general. This patch changes things to avoid the throttling while we sleep.

Namely, it should have been added after wait_for_device_probe(), which is called only if the image partition hasn't been specified yet. Also, it's reasonable to check if the image partition is present and only wait for the device probing and SCSI scanning to complete if it is not the case.

We perhaps should flag the filesystem as being corrupted if we see a special file (named pipes, device nodes, Unix domain sockets, etc.) with the EXTENTS_FL flag, but e2fsck doesn't currently check this case, so we'll just ignore this for now, since it's harmless. Without this fix, a special device with the extents flag is flagged as an error by the kernel, so it is impossible to access or delete the inode, but e2fsck doesn't see it as a problem, leading to confused/frustrated users.

The following patch adds a transfer of operating state from the real device to the VLAN device when the real device is administratively set up or down, and sets the carrier state up or down during init, open and close of the VLAN device. This permits observers above the VLAN device that care about the carrier state (bonding's link monitor, for example) to receive updates for administrative changes by more closely mimicing the behavior of real devices.

This patch is preparation for replacing all uses of ".head.text" or ".text.head" in the kernel with macros, so that the section name can later be changed without having to touch a lot of the kernel. Since some linker scripts do more complex things than referencing HEAD_TEXT, we add a HEAD_TEXT_SECTION macro that just contains the actual name. I've defined HEAD_TEXT_SECTION in a new header, include/linux/section-names.h, so that this section name only needs to appear in one place. I anticipate creating similar macro structures for a number of other section names. The long-term goal here is to be able to change the kernel's magic section names to those that are compatible with -ffunction-sections -fdata-sections. This requires renaming all magic sections with names of the form ".text.foo".

Therefore this feature reports false positives. A real fix for this issue is to introduce a new notifier event which sent _after_ the driver has deinitialized itself.

Overview + +Kernel CAPI operates as a dispatching layer between CAPI applications and CAPI +hardware drivers. Hardware drivers register ISDN devices (controllers, in CAPI +lingo) with Kernel CAPI to indicate their readiness to provide their service +to CAPI applications. CAPI applications also register with Kernel CAPI, +requesting association with a CAPI device. Kernel CAPI then dispatches the +application registration to an available device, forwarding it to the +corresponding hardware driver. Kernel CAPI then forwards CAPI messages in both +directions between the application and the hardware driver. + + +2. Driver and Device Registration + +CAPI drivers optionally register themselves with Kernel CAPI by calling the +Kernel CAPI function register_capi_driver() with a pointer to a struct +capi_driver. This structure must be filled with the name and revision of the +driver, and optionally a pointer to a callback function, add_card(). The +registration can be revoked by calling the function unregister_capi_driver() +with a pointer to the same struct capi_driver. + +CAPI drivers must register each of the ISDN devices they control with Kernel +CAPI by calling the Kernel CAPI function attach_capi_ctr() with a pointer to a +struct capi_ctr before they can be used. This structure must be filled with +the names of the driver and controller, and a number of callback function +pointers which are subsequently used by Kernel CAPI for communicating with the +driver. The registration can be revoked by calling the function +detach_capi_ctr() with a pointer to the same struct capi_ctr. + +Before the device can be actually used, the driver must fill in the device +information fields 'manu', 'version', 'profile' and 'serial' in the capi_ctr +structure of the device, and signal its readiness by calling capi_ctr_ready(). +From then on, Kernel CAPI may call the registered callback functions for the +device. + +If the device becomes unusable for any reason (shutdown, disconnect ...), the +driver has to call capi_ctr_reseted(). This will prevent further calls to the +callback functions by Kernel CAPI. + + +3. Application Registration and Communication + +Kernel CAPI forwards registration requests from applications (calls to CAPI +operation CAPI_REGISTER) to an appropriate hardware driver by calling its +register_appl() callback function. A unique Application ID (ApplID, u16) is +allocated by Kernel CAPI and passed to register_appl() along with the +parameter structure provided by the application. This is analogous to the +open() operation on regular files or character devices. + +After a successful return from register_appl(), CAPI messages from the +application may be passed to the driver for the device via calls to the +send_message() callback function. The CAPI message to send is stored in the +data portion of a skb. Conversely, the driver may call Kernel CAPI's +capi_ctr_handle_message() function to pass a received CAPI message to Kernel +CAPI for forwarding to an application, specifying its ApplID. + +Format and semantics of CAPI messages are specified in the CAPI 2.0 standard. + +Deregistration requests (CAPI operation CAPI_RELEASE) from applications are +forwarded as calls to the release_appl() callback function, passing the same +ApplID as with register_appl(). After return from release_appl(), no CAPI +messages for that application may be passed to or from the device anymore. + + +4.

On a 128GB POWER6 box it ends up as 32MB: IP route cache hash table entries: 4194304 (order: 9, 33554432 bytes) It would be nice to cap this for memory consumption reasons, but a massive hashtable also causes a significant spike when measuring OS jitter. With a 32MB hashtable and 4 million entries, rt_worker_func is taking 5 ms to complete. On another system with more memory it's taking 14 ms. Even though rt_worker_func does call cond_sched() to limit its impact, in an HPC environment we want to keep all sources of OS jitter to a minimum. With the patch applied we limit the number of entries to 512k which can still be overriden by using the rt_entries boot option: IP route cache hash table entries: 524288 (order: 6, 4194304 bytes) With this patch rt_worker_func now takes 0.460 ms on the same system.

So, what's happening here is that the drive is reporting a sense of 2/4/1 ("logical unit is becoming ready") from sr_test_unit_ready(), and then we ask for the media event notification before checking that result at all. The check_media_event_descriptor() call isn't getting a check condition, but it's also reporting that the tray is closed and that there's no media. In actuality it doesn't yet know if there's media or not, but there's no way to express that in the media event status field. My current thought is that if it told us the device isn't yet ready, we should return that immediately, since there's nothing that'll tell us any more data than that reliably: Signed-off-by: James Bottomley --- drivers/scsi/sr_ioctl.c | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/drivers/scsi/sr_ioctl.c b/drivers/scsi/sr_ioctl.c index d92ff512d21..291236e6e43 100644 --- a/drivers/scsi/sr_ioctl.c +++ b/drivers/scsi/sr_ioctl.c @@ -309,6 +309,11 @@ int sr_drive_status(struct cdrom_device_info *cdi, int slot) if (0 == sr_test_unit_ready(cd->device, &sshdr)) return CDS_DISC_OK; + /* SK/ASC/ASCQ of 2/4/1 means "unit is becoming ready" */ + if (scsi_sense_valid(&sshdr) && sshdr.sense_key == NOT_READY + && sshdr.asc == 0x04 && sshdr.ascq == 0x01) + return CDS_DRIVE_NOT_READY; + if (!cdrom_get_media_event(cdi, &med)) { if (med.media_present) return CDS_DISC_OK; -- cgit v1.2.3 From e7ee4cc04b058d1eae9c1ac359031301b1798e3f Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Sat, 4 Apr 2009 00:35:42 +0900 Subject: [SCSI] sg: return EFAULT for an invalid user address blk_rq_unmap_user() returns EFAULT if a program passes an invalid address to kernel (the kernel fails to copy data to user space). sg needs to pass the returned value to user space instead of ignoring it.

The response handler of the just started exchange config should wait for the completion by performing a down on this semaphore. Since this semaphore is still positive from the ERP enqueue the handler won't wait and therefore the exchange config will always fail leaving the adapter in error. The problem can be solved by performing the down on the semaphore before starting an ERP task. This is the logically correct order. Only walk the ERP loop if there is a task to perform.

If a DATA_OUT for a R2T fails then we will want to drop the session, because it means we got a bad request from the target (iscsi protocol error). This patch has us propogate the error upwards so libiscsi_tcp or libiscsi can decide what the best action is to take. It also fixes a bug where we could try to grab the session lock while holding it, because if iscsi_tcp drops the session in the pdu setup callout the session lock is held when setting up the scsi cmd pdu.

The only reference to them is through any outstanding exchanges pending on the rogue ports. If the module is removed while a retry is set on a rogue port (say a Plogi retry for instance), this retry is not cancelled because there is no reference to the rogue port in the discovery rports list. Thus the local port can clean itself up, delete the exchange pool, and then the rogue port timeout can fire and try to start up another exchange. This patch tracks the rogue ports in a new list disc->rogue_rports. Creating a new list instead of using the disc->rports list keeps remote port code change to a minimum. 1) Whenever a rogue port is created, it is immediately added to the disc->rogue_rports list. 2) When the rogues port goes to ready, it is removed from the rogue list and the real remote port is added to the disc->rports list 3) The removal of the rogue from the disc->rogue_rports list is done in the context of the fc_rport_work() workQ thread in discovery callback. 4) Real rports are removed from the disc->rports list like before. Lookup is done only in the real rports list. This avoids making large changes to the remote port code. 5) In fc_disc_stop_rports, the rogues list is traversed in addition to the real list to stop the rogue ports and issue logoffs on them. This way, rogue ports get cleaned up when the local port goes away. 6) rogue remote ports are not removed from the list right away, but removed late in fc_rport_work() context, multiple threads can find the same remote port in the list and call rport_logoff(). Rport_logoff() only continues with the logoff if port is not in NONE state, thus preventing multiple logoffs and multiple list deletions. 7) Since the rport is removed from the disc list at a later stage (in the disc callback), incoming frames can find the rport even if rport_logoff() has been called on the rport. When rport_logoff() is called, the rport state is set to NONE, and we are trying to cancel all exchanges and retries on that port. While in this state, if an incoming Plogi/Prli/Logo or other frames match the rport, we should not reply because the rport is in the NONE state. Just drop the frame, since the rport will be deleted soon in the disc callback (fc_rport_work) 8) In fc_disc_single(), remove rport lookup and call to fc_disc_del_target. fc_disc_single() is called from recv_rscn_req() where rport lookup and rport_logoff is already done.

In OSD2r01-r04 it was aligned on 2 bytes. (This is because in OSD2r01 the complete element was 8 bytes padded at end but the header was not adjusted and caused permanent miss-alignment.) OSD1 elements are not padded and might be or might not be aligned. OSD1 is still supported. In this code we do all the code re-factoring to separate OSD1/OSD2 differences but do not change actual wire format. All wire format changes will happen in one patch later, for bisect-ability.

So for example on dm6467, GPIO-42 is the last GPIO, and trying to use GPIO-43 now fails cleanly; or GPIO-72 on dm6446. - Enable GPIO interrupts on each 16-bit GPIO-irq bank ... previously, only the first five were enabled, so GPIO-80 and above (on dm355) wouldn't trigger IRQs. - Use the right IRQ for each GPIO bank. The wrong values were used for dm355 chips, so GPIO IRQs got routed incorrectly. - Handle up to four pairs of 16-bit GPIO banks ... previously only three were handled, so accessing GPIO-96 and up (e.g. on dm355) would oops. - Update several comments that were dm6446-specific. Verified by receiving GPIO-1 (dm9000) and GPIO-5 (msp430) IRQs on the DM355 EVM. One thing this doesn't do is handle the way some of the GPIO numbers on dm6467 are reserved but aren't valid as GPIOs. Some bitmap logic could fix that if needed.

This meant the common case of no acls resulted in expensive btree searches every time the kernel checked permissions (which is quite often). This is a modified version of Linus' original patch: Properly set initial acl fields to BTRFS_ACL_NOT_CACHED in the inode. This forces an acl lookup when permission checks are done. Fix btrfs_get_acl to avoid lookups and locking when the inode acls fields are set to null. Fix btrfs_get_acl to use the right return value from __btrfs_getxattr when deciding to cache a NULL acl. It was storing a NULL acl when __btrfs_getxattr return -ENOENT, but __btrfs_getxattr was actually returning -ENODATA for this case.

Fixing this required going over the code and making sure the rexmit entry was properly removed based on the cm_node's state and packet received. Also when receiving a FIN packet, check seq# and make sure there were no errors before calling handle_fin(). Following are the changes done in nes_cm.c: * handle_ack_pkt() needs to return error value, so in case of error, handle_fin() is not called. Some cleanup done while going over the code. * handle_rst_pkt(), handling of cm_node's NES_CM_STATE_LAST_ACK is missing. * process_packet(), in case of FIN only packet is received, call check_seq() before processing. * in handle_fin_pkt(), we are calling cleanup_retrans_entry() for all conditions, even if the packets need to be dropped.

This unfortunatly added a penalty when a frame is transmitted, since we have at TX completion time to call sock_wfree() to perform necessary memory accounting. This calls sock_def_write_space() and utimately scheduler if any thread is waiting on the socket. Thread(s) waiting for an incoming frame was scheduled, then had to sleep again as event was meaningless. (All threads waiting on a socket are using same sk_sleep anchor) This adds lot of extra wakeups and increases latencies, as noted by Christoph Lameter, and slows down softirq handler. Reference : http://marc.info/?l=linux-netdev&m=124060437012283&w=2 Fortunatly, Davide Libenzi recently added concept of keyed wakeups into kernel, and particularly for sockets (see commit 37e5540b3c9d838eb20f2ca8ea2eb8072271e403 epoll keyed wakeups: make sockets use keyed wakeups) Davide goal was to optimize epoll, but this new wakeup infrastructure can help non epoll users as well, if they care to setup an appropriate handler. This patch introduces new DEFINE_WAIT_FUNC() helper and uses it in wait_for_packet(), so that only relevant event can wakeup a thread blocked in this function.

The problem part is the dedicated pairing when using Legacy Pairing (Bluetooth 2.0 and before). At that point no user is present and pairing attempts will be disconnected within 10 seconds or less. In previous kernel version this was not a problem since the disconnect timeout wasn't triggered on incoming connections for the first time. However this caused issues with broken host stacks that kept the connections around after dedicated pairing. When the support for Simple Pairing got added, the link establishment procedure needed to be changed and now causes issues when using Legacy Pairing When using Simple Pairing it is possible to do a proper reference counting of ACL link users. With Legacy Pairing this is not possible since the specification is unclear in some areas and too many broken Bluetooth devices have already been deployed. So instead of trying to deal with all the broken devices, a special pairing timeout will be introduced that increases the timeout to 60 seconds when pairing is triggered. If a broken devices now puts the stack into an unforeseen state, the worst that happens is the disconnect timeout triggers after 120 seconds instead of 4 seconds. This allows successful pairings with legacy and broken devices now.

With the usage of Simple Pairing it is required that all connections (except the ones for SDP) are encrypted. So even the low security requirement mandates an encrypted connection when using Simple Pairing. When using Legacy Pairing (for Bluetooth 2.0 devices and older) this is not required since it causes interoperability issues. To support this properly the low security requirement translates into different host controller transactions depending if Simple Pairing is supported or not. However in case of Simple Pairing the command to switch on encryption after a successful authentication is not triggered for the low security mode. This patch fixes this and actually makes the logic to differentiate between Simple Pairing and Legacy Pairing a lot simpler.

This patch adds a multi-touch (MT) protocol which allows drivers to report details for an arbitrary number of fingers. The driver sends a SYN_MT_REPORT event via the input_mt_sync() function when a complete finger has been reported. In order to stay compatible with existing applications, the data reported in a finger packet must not be recognized as single-touch events. In addition, all finger data must bypass input filtering, since subsequent events of the same type refer to different fingers. A set of ABS_MT events with the desired properties are defined. The events are divided into categories, to allow for partial implementation. The minimum set consists of ABS_MT_TOUCH_MAJOR, ABS_MT_POSITION_X and ABS_MT_POSITION_Y, which allows for multiple fingers to be tracked. If the device supports it, the ABS_MT_WIDTH_MAJOR may be used to provide the size of the approaching finger. Anisotropy and direction may be specified with ABS_MT_TOUCH_MINOR, ABS_MT_WIDTH_MINOR and ABS_MT_ORIENTATION. Devices with more granular information may specify general shapes as blobs, i.e., as a sequence of rectangular shapes grouped together by a ABS_MT_BLOB_ID. Finally, the ABS_MT_TOOL_TYPE may be used to specify whether the touching tool is a finger or a pen.

On older kernels there was a reader/writer lock per table which was a performance bottleneck. In 2.6.30-rc, this was converted to use RCU and the counters/rules which solved the performance problems for do_table but made replacing rules much slower because of the necessary RCU grace period. This version uses a per-cpu set of spinlocks and counters to allow to table processing to proceed without the cache thrashing of a global reader lock and keeps the same performance for table updates.

It would not read the eeprom. After some bisects, I realized this has been like that since forever (at least 2.6.18). The problem is that shutdown is doing the same thing that suspend does and puts the device in D3 state. I couldn't find a way to get the device back to a sane state in the probe function. So, based on some similar patches from Rafael J. Wysocki for e1000, e1000e, and ixgbe, I wrote this one for e100. Signed-off-by: Thadeu Lima de Souza Cascardo Acked-by: "Rafael J.

If the whole device is successfully erased, erase_chip() will return 0, and the code will fall through to the "else" clause, and do sector-by-sector erase in addition to the whole-chip erase. This patch corrects that. Also, the MAX_READY_WAIT_COUNT is insufficient for an m25p16 connected to a 400 MHz powerpc. Increasing it allows me to successfully program the device on my board.

This breaks static build of video4linux drivers, that use generic CPU i2c adapter drivers and the v4l2-subdev subsystem, because during video4linux probing the v4l2-subdev core requires a struct i2c_adapter context, which cannot be satisfied before the i2c subsystem is initialised. Moving drivers/media after drivers/i2c fixes this problem. The best way to trigger action is by submitting a patch:-) So, let's see what comes out of it - on the one hand I don't see any reason why media has to be linked this early, and nobody was able to give me one yesterday as this problem has been discussed on linux-media, OTOH, maybe indeed it would be better to move i2c the whole way up above media, but that'd be much bigger of a change, I think. -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Signed-off-by: Guennadi Liakhovetski Acked-by: Jean Delvare Signed-off-by: Mauro Carvalho Chehab --- drivers/Makefile | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/Makefile b/drivers/Makefile index 2618a6169a1..1266ead6ace 100644 --- a/drivers/Makefile +++ b/drivers/Makefile @@ -36,7 +36,7 @@ obj-$(CONFIG_FB_INTEL) += video/intelfb/ obj-y += serial/ obj-$(CONFIG_PARPORT) += parport/ -obj-y += base/ block/ misc/ mfd/ media/ +obj-y += base/ block/ misc/ mfd/ obj-$(CONFIG_NUBUS) += nubus/ obj-y += macintosh/ obj-$(CONFIG_IDE) += ide/ @@ -71,7 +71,7 @@ obj-$(CONFIG_GAMEPORT) += input/gameport/ obj-$(CONFIG_INPUT) += input/ obj-$(CONFIG_I2O) += message/ obj-$(CONFIG_RTC_LIB) += rtc/ -obj-y += i2c/ +obj-y += i2c/ media/ obj-$(CONFIG_W1) += w1/ obj-$(CONFIG_POWER_SUPPLY) += power/ obj-$(CONFIG_HWMON) += hwmon/ -- cgit v1.2.3 From 272aa3966b3244e576c5c07bfff77ea320b89317 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Fri, 17 Apr 2009 10:56:51 -0300 Subject: V4L/DVB (11568): cx18: Fix the handling of i2c bus registration error * Return actual error values as returned by the i2c subsystem, rather than 0 or 1. * If the registration of the second bus fails, unregister the first one before exiting, otherwise we are leaking resources.

This patch fixes this by checking the OOM bit in the NAPI poll handler before attempting to do rx refill. This means that once OOM occurs, we won't try to do any memory allocations again until the next invocation of the poll handler. While we're at it, change the OOM flag to be a single bit instead of one bit per receive queue since OOM is a system state rather than a per-queue state, and cancel the OOM timer on entry to the NAPI poll handler if it's running to prevent it from firing when we've already come out of OOM.

This can under heavy traffic occasionally lead to small numbers being added to the upper half of the 64bit mib counter even though no 32bit wrap has occured. Since we poll the mib counters at least every 30 seconds anyway, we might as well just skip the reads of the upper halves of the hardware counters without breaking the stats, which this patch does.

This has been reported via bugzilla a while ago (#717) and has recently also shown up via lockdep. So allocate a temporary buffer to format the kernel getbmap structures into and then copy them out after dropping the locks. A little problem with this is that we limit the number of extents we can copy out by the maximum allocation size, but I see no real way around that.

This was useful to avoid regressions, but is long overdue to be removed. Now that the Kerberos (asn/spnego) code is working in fs/cifs/sess.c, and the NTLMSSP code moved (NTLMSSP blob setup be rewritten with the next patch in this series) quite a bit of dead code from fs/cifs/connect.c now can be removed. This old code should have been removed last year, but the earlier krb5 patches did not move/remove the NTLMSSP code which we had asked to be done first. Since no one else volunteered, I am doing it now. It is extremely important that we continue to examine the documentation for this area, to make sure our code continues to be uptodate with changes since Windows 2003.

This document +describes the multi-touch (MT) protocol which allows kernel drivers to +report details for an arbitrary number of fingers. + + +Usage +----- + +Anonymous finger details are sent sequentially as separate packets of ABS +events. Only the ABS_MT events are recognized as part of a finger +packet. The end of a packet is marked by calling the input_mt_sync() +function, which generates a SYN_MT_REPORT event. The end of multi-touch +transfer is marked by calling the usual input_sync() function. + +A set of ABS_MT events with the desired properties is defined. The events +are divided into categories, to allow for partial implementation. The +minimum set consists of ABS_MT_TOUCH_MAJOR, ABS_MT_POSITION_X and +ABS_MT_POSITION_Y, which allows for multiple fingers to be tracked. If the +device supports it, the ABS_MT_WIDTH_MAJOR may be used to provide the size +of the approaching finger. Anisotropy and direction may be specified with +ABS_MT_TOUCH_MINOR, ABS_MT_WIDTH_MINOR and ABS_MT_ORIENTATION. Devices with +more granular information may specify general shapes as blobs, i.e., as a +sequence of rectangular shapes grouped together by an +ABS_MT_BLOB_ID. Finally, the ABS_MT_TOOL_TYPE may be used to specify +whether the touching tool is a finger or a pen or something else. + + +Event Semantics +--------------- + +The word "contact" is used to describe a tool which is in direct contact +with the surface. A finger, a pen or a rubber all classify as contacts. + +ABS_MT_TOUCH_MAJOR + +The length of the major axis of the contact. The length should be given in +surface units. If the surface has an X times Y resolution, the largest +possible value of ABS_MT_TOUCH_MAJOR is sqrt(X^2 + Y^2), the diagonal. + +ABS_MT_TOUCH_MINOR + +The length, in surface units, of the minor axis of the contact. If the +contact is circular, this event can be omitted. + +ABS_MT_WIDTH_MAJOR + +The length, in surface units, of the major axis of the approaching +tool. This should be understood as the size of the tool itself. The +orientation of the contact and the approaching tool are assumed to be the +same. + +ABS_MT_WIDTH_MINOR + +The length, in surface units, of the minor axis of the approaching +tool. Omit if circular. + +The above four values can be used to derive additional information about +the contact. The ratio ABS_MT_TOUCH_MAJOR / ABS_MT_WIDTH_MAJOR approximates +the notion of pressure. The fingers of the hand and the palm all have +different characteristic widths [1]. + +ABS_MT_ORIENTATION + +The orientation of the ellipse. The value should describe half a revolution +clockwise around the touch center. The scale of the value is arbitrary, but +zero should be returned for an ellipse aligned along the Y axis of the +surface. As an example, an index finger placed straight onto the axis could +return zero orientation, something negative when twisted to the left, and +something positive when twisted to the right. This value can be omitted if +the touching object is circular, or if the information is not available in +the kernel driver. + +ABS_MT_POSITION_X + +The surface X coordinate of the center of the touching ellipse. + +ABS_MT_POSITION_Y + +The surface Y coordinate of the center of the touching ellipse. + +ABS_MT_TOOL_TYPE + +The type of approaching tool. A lot of kernel drivers cannot distinguish +between different tool types, such as a finger or a pen. In such cases, the +event should be omitted. The protocol currently supports MT_TOOL_FINGER and +MT_TOOL_PEN [2]. + +ABS_MT_BLOB_ID + +The BLOB_ID groups several packets together into one arbitrarily shaped +contact. This is a low-level anonymous grouping, and should not be confused +with the high-level contactID, explained below. Most kernel drivers will +not have this capability, and can safely omit the event. + + +Finger Tracking +--------------- + +The kernel driver should generate an arbitrary enumeration of the set of +anonymous contacts currently on the surface. The order in which the packets +appear in the event stream is not important. + +The process of finger tracking, i.e., to assign a unique contactID to each +initiated contact on the surface, is left to user space; preferably the +multi-touch X driver [3]. In that driver, the contactID stays the same and +unique until the contact vanishes (when the finger leaves the surface). The +problem of assigning a set of anonymous fingers to a set of identified +fingers is a euclidian bipartite matching problem at each event update, and +relies on a sufficiently rapid update rate. + +Notes +----- + +In order to stay compatible with existing applications, the data +reported in a finger packet must not be recognized as single-touch +events. In addition, all finger data must bypass input filtering, +since subsequent events of the same type refer to different fingers. + +The first kernel driver to utilize the MT protocol is the bcm5974 driver, +where examples can be found. + +[1] With the extension ABS_MT_APPROACH_X and ABS_MT_APPROACH_Y, the +difference between the contact position and the approaching tool position +could be used to derive tilt. +[2] The list can of course be extended. +[3] The multi-touch X driver is currently in the prototyping stage. At the +time of writing (April 2009), the MT protocol is not yet merged, and the +prototype implements finger matching, basic mouse support and two-finger +scrolling. The project aims at improving the quality of current multi-touch +functionality available in the synaptics X driver, and in addition +implement more advanced gestures. -- cgit v1.2.3 From d185cda7712fd1d9e349174639d76eadc66679be Mon Sep 17 00:00:00 2001 From: Steve French Date: Thu, 30 Apr 2009 17:45:10 +0000 Subject: [CIFS] rename cifs_strndup to cifs_strndup_from_ucs In most cases, cifs_strndup is converting from Unicode (UCS2 / UTF-32) to the configured local code page for the Linux mount (usually UTF8), so Jeff suggested that to make it more clear that cifs_strndup is doing a conversion not just memory allocation and copy, rename the function to including "from_ucs" (ie Unicode) Signed-off-by: Steve French --- fs/cifs/CHANGES | 6 +++++- fs/cifs/cifs_unicode.c | 6 +++--- fs/cifs/cifs_unicode.h | 7 ++++--- fs/cifs/cifssmb.c | 12 ++++++------ fs/cifs/connect.c | 5 +++-- fs/cifs/sess.c | 8 ++++---- 6 files changed, 25 insertions(+), 19 deletions(-) diff --git a/fs/cifs/CHANGES b/fs/cifs/CHANGES index 1bf81813627..1b0643c2eac 100644 --- a/fs/cifs/CHANGES +++ b/fs/cifs/CHANGES @@ -2,7 +2,11 @@ Version 1.58 ------------ Guard against buffer overruns in various UCS-2 to UTF-8 string conversions when the UTF-8 string is composed of unusually long (more than 4 byte) converted -characters. +characters.

The ocfs2 directory index updates two blocks when we remove an entry - the dx root and the dx leaf. OCFS2_DELETE_INODE_CREDITS was only accounting for the dx leaf. This shows up when ocfs2_delete_inode() runs out of credits in jbd2_journal_dirty_metadata() at "J_ASSERT_JH(jh, handle->h_buffer_credits > 0);". The test that caught this was running dirop_file_racer from the ocfs2-test suite with a 250-character filename PREFIX. Run on a 512B blocksize, it forces the orphan dir index to grow large enough to trigger.

That's not always the case. Instead of passing "max_len" to the string converter, pass "min(len, max_len)", which makes it do the right thing while still keeping the parser confined to the response.

Instead of having compat-power, oprofile will go to family naming convention and use ibm-compat-v. Currently only ibm-compat-v1 will be defined. The notion of compatibility events just started with POWER6. So there is no way that any other tool could exist that is using these oprofile_cpu_type strings we want to change.

This is resulting in modpost's main function calling read_markers() and then write_markers() on the same file. We then have read_markers() mmap'ing the file, and writer_markers() opening that same file for writing. The issue is that read_markers() exits without munmap'ing the file and is as a matter holding a reference on Modules.markers. When write_markers() is opening that very same file for writing, we still have a reference on it and cygwin (Windows?) is then making fopen() fail with EPERM. Calling release_file() before exiting read_markers() clears that reference (and memory leak) and fopen() then succeeds. Tested on both cygwin (1.3.22) and Linux.

But this heuristic has two problems: it will miss a bad section that has no relocations, and it will incorrectly flag many gcc-generated sections as bad when compiling with -ffunction-sections -fdata-sections. On mips it fixes a lot of bogus warnings with gcc 4.4.0 lije this one: WARNING: crypto/cryptd.o (.text.T.349): unexpected section name.

This breaks the generic tasklet based interrupt resend mechanism which is used when the hardware has no way to retrigger the interrupt.

Avoid an endless loop issue by requiring that a highres valid clocksource be installed before we call tick_periodic() in a loop when using ONESHOT mode. The result is we will only increment jiffies once per interrupt until a continuous hardware clocksource is available. Without this, we can run into a endless loop, where each cycle through the loop, jiffies is updated which increments time by tick_period or more (due to clock steering), which can cause the event programming to think the next event was before the newly incremented time and fail causing tick_periodic() to be called again and the whole process loops forever.

This allows the filesystem to have full control of page dirtying events coming from the VM. Rather than simply hold the page locked over the page_mkwrite call, we call page_mkwrite with the page unlocked and allow callers to return with it locked, so filesystems can avoid LOR conditions with page lock. The problem with the current scheme is this: a filesystem that wants to associate some metadata with a page as long as the page is dirty, will perform this manipulation in its ->page_mkwrite. It currently then must return with the page unlocked and may not hold any other locks (according to existing page_mkwrite convention). In this window, the VM could write out the page, clearing page-dirty. The filesystem has no good way to detect that a dirty pte is about to be attached, so it will happily write out the page, at which point, the filesystem may manipulate the metadata to reflect that the page is no longer dirty. It is not always possible to perform the required metadata manipulation in ->set_page_dirty, because that function cannot block or fail. The filesystem may need to allocate some data structure, for example. And the VM cannot mark the pte dirty before page_mkwrite, because page_mkwrite is allowed to fail, so we must not allow any window where the page could be written to if page_mkwrite does fail. This solution of holding the page locked over the 3 critical operations (page_mkwrite, setting the pte dirty, and finally setting the page dirty) closes out races nicely, preventing page cleaning for writeout being initiated in that window. This provides the filesystem with a strong synchronisation against the VM here. - Sage needs this race closed for ceph filesystem. - Trond for NFS (http://bugzilla.kernel.org/show_bug.cgi?id=12913). - I need it for fsblock. - I suspect other filesystems may need it too (eg. btrfs). - I have converted buffer.c to the new locking. Even simple block allocation under dirty pages might be susceptible to i_size changing under partial page at the end of file (we also have a buffer.c-side problem here, but it cannot be fixed properly without this patch). - Other filesystems (eg. NFS, maybe btrfs) will need to change their page_mkwrite functions themselves. [ This also moves page_mkwrite another step closer to fault, which should eventually allow page_mkwrite to be moved into ->fault, and thus avoiding a filesystem calldown and page lock/unlock cycle in __do_fault. ] [akpm@linux-foundation.org: fix derefs of NULL ->mapping] Cc: Sage Weil Cc: Trond Myklebust Signed-off-by: Nick Piggin Cc: Valdis Kletnieks Cc: Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- Documentation/filesystems/Locking | 24 ++++++--- fs/buffer.c | 10 ++-- mm/memory.c | 108 +++++++++++++++++++++++++++----------- 3 files changed, 98 insertions(+), 44 deletions(-) diff --git a/Documentation/filesystems/Locking b/Documentation/filesystems/Locking index 76efe5b71d7..3120f8dd2c3 100644 --- a/Documentation/filesystems/Locking +++ b/Documentation/filesystems/Locking @@ -512,16 +512,24 @@ locking rules: BKL mmap_sem PageLocked(page) open: no yes close: no yes -fault: no yes -page_mkwrite: no yes no +fault: no yes can return with page locked +page_mkwrite: no yes can return with page locked access: no yes - ->page_mkwrite() is called when a previously read-only page is -about to become writeable.

It doesn't call mem_cgroup_out_of_memory and doesn't update last_oom_jiffies, so pagefault_out_of_memory invokes global OOM. 2. Considering hierarchy, shrinking has to be done from the mem_over_limit, not from the memcg which the page would be charged to. mem_cgroup_try_charge_swapin() does all of these things properly, so we use it and call cancel_charge_swapin when it succeeded.

For him everything above unicode 0xa0 was corrupted. After some digging there seems to be a little culprit in vgacon since the beginning of ages (well git). The function vgacon_font_get will store the number of characters correctly in font->charcount but then calls to vgacon_do_font_op(..., 0, 0). Which means only the lower 256 characters are actually stored to the fontdata. The rest is left untouched. So the next time that saved data is used, the garbled font appears.

That happens because aout binary handler gets on the top of the binfmt list due to late registration, and kernel attempts to execute the binary without preparatory work that must be done by binfmt_loader. Fixed by changing the registration order of the default binfmt handlers using list_add_tail() and introducing insert_binfmt() function which places new handler on the top of the binfmt list. This might be generally useful for installing arch-specific frontends for default handlers or just for overriding them.

But NR_CPUS proportional isn't good calculation. In general, possibility of lock contention is proportional to the number of online cpus, not theorical maximum cpus (NR_CPUS). The current kernel has generic percpu-counter stuff. using it is right way. it makes code simplify and percpu_counter_read_positive() don't make underflow issue.

On systems without OF, this comes from a flattened device tree blob. This blob is usually generated by dtc, a tool which compiles a text description of the device tree into the flattened format used by the kernel. Sometimes, the bootwrapper makes small changes to the pre-compiled device tree blob (e.g. filling in the size of RAM). To do this it uses the libfdt library. Because these are only used on powerpc, the code for both these tools is included under arch/powerpc/boot (these were imported and are periodically updated from the upstream dtc tree). However, the microblaze architecture, currently being prepared for merging to mainline also uses dtc to produce device tree blobs. A few other archs have also mentioned some interest in using dtc. Therefore, this patch moves dtc and libfdt from arch/powerpc into scripts, where it can be used by any architecture. The vast bulk of this patch is a literal move, the rest is adjusting the various Makefiles to use dtc and libfdt correctly from their new locations.

EEM is different from the Ethernet Control Model (ECM) currently supported by the "CDC Ethernet" driver. One key difference is that it doesn't require of USB interface alternate settings to manage interface state; some maldesigned hardware can't handle that part of USB. It also avoids a separate USB interface for control and status updates.

This is important wrt the key flags as they are used during key clearing and if they are not set when the key is set the key cannot be cleared completely. This addresses the many occurences of the WARN found in iwl_set_tkip_dynamic_key_info() and tracked in http://www.kerneloops.org/searchweek.php?search=iwl_set_dynamic_key If calling iwl_set_tkip_dynamic_key_info()/iwl_remove_dynamic_key() pair a few times in a row will cause that we run out of key space. This is because the index stored in the key flags is used by iwl_remove_dynamic_key() to decide if it should remove the key. Unfortunately the key flags, and hence the key index is currently only set at the time the key is written to the device (in iwl_update_tkip_key()) and _not_ in iwl_set_tkip_dynamic_key_info().

The whole approach is actually fully broken and based on assumptions that are no longer valid. With the introduction of Simple Pairing support, the creation of low-level ACL links got changed. This change invalidates the reason why in the past two independent work queues have been used for adding/removing sysfs devices. The adding of the actual sysfs device is now postponed until the host controller successfully assigns an unique handle to that link. So the real synchronization happens inside the controller and not the host. The only left-over problem is that some internals of the sysfs device handling are not initialized ahead of time. This leaves potential access to invalid data and can cause various NULL pointer dereferences. To fix this a new function makes sure that all sysfs details are initialized when an connection attempt is made. The actual sysfs device is only registered when the connection has been successfully established. To avoid a race condition with the registration, the check if a device is registered has been moved into the removal work. As an extra protection two flush_work() calls are left in place to make sure a previous add/del work has been completed first.

This is because the driver in a virtual environment doesn't get to run instructions *AT ALL* when an interrupt is asserted. The interrupt code runs immediately and this recent bug fix allows an interrupt to be possible when the interrupt handler will reject it (due to the new code), when being called from any path in the driver that holds the E1000_RESETTING flag. the driver should use the __E1000_DOWN flag instead of the __E1000_RESETTING flag to prevent interrupt execution while reconfiguring the hardware.

Thus, the i2c bus connected to the controller gets stuck afterwards. I have seen this kind of error on a custom board in certain load situations most probably caused by interference or noise. A possible reaction is to let the controller generate a STOP condition. This is documented in the PCA9564 data sheet (2006-09-01) and the same is done for other NACK states as well. Further, state 0x38 isn't handled completely, either. Try to do another START in this case like the data sheet says. As this couldn't be tested, I've added a comment to try to reset the chip if the START doesn't help as suggested by Wolfram Sang.

To see that, run the following command on a fbdev console with a 24bpp video mode, using a non-accelerated driver such as (u)vesafb: reset ; echo -e '\e[41mtest\e[K' The expected result is 'test' displayed on a line with red background. Instead of that, 'test' has a red background, but the rest of the line (rendered using fillrect()) contains a distored colorful pattern. This patch fixes the problem by correctly computing rotation shifts. It has been tested in a 24bpp mode on 32- and 64-bit little-endian machines.

The problem is that under NOMMU conditions it is really important to be able to allocate large contiguous chunks of memory, but when munmap() or exit_mmap() releases big stretches of memory, return of these to the buddy allocator can be deferred, and when it does finally happen, it can be in small chunks. Whilst the fragmentation this incurs isn't so much of a problem under MMU conditions as userspace VM is glued together from individual pages with the aid of the MMU, it is a real problem if there isn't an MMU. By clamping the page freeing queue size to 0, pages are returned to the allocator immediately, and the buddy detector is more likely to be able to glue them together into large chunks immediately, and fragmentation is less likely to occur. By disabling batching of frees, and by turning off the trimming of excess space during boot, Coldfire can manage to boot.

Make the initial setting of this variable a Kconfig configuration option. The reason there can be excess space is that the allocator only allocates in power-of-2 size chunks, but mmap()'s can be made in sizes that aren't a power of 2. There are two alternatives: (1) Keep the excess as dead space. The dead space then remains unused for the lifetime of the mapping. Mappings of shared objects such as libc, ld.so or busybox's text segment may retain their dead space forever. (2) Return the excess to the allocator. This means that the dead space is limited to less than a page per mapping, but it means that for a transient process, there's more chance of fragmentation as the excess space may be reused fairly quickly. During the boot process, a lot of transient processes are created, and this can cause a lot of fragmentation as the pagecache and various slabs grow greatly during this time. By turning off the trimming of excess space during boot and disabling batching of frees, Coldfire can manage to boot. A better way of doing things might be to have /sbin/init turn this option off. By that point libc, ld.so and init - which are all long-duration processes - have all been loaded and trimmed.

When md is loading a bitmap which it knows is out of date, it fills each page with 1s and writes it back out again. However the write_page call makes used of bitmap->file_pages and bitmap->last_page_size which haven't been set correctly yet. So this can sometimes fail. Move the setting of file_pages and last_page_size to before the call to write_page. This bug can cause the assembly on an array to fail, thus making the data inaccessible. Hence I think it is a suitable candidate for -stable.

If we have a raid10 with multiple missing devices, and we recover just one of these to a spare, then we risk (depending on the bitmap and array chunk size) clearing bits of the bitmap for which recovery isn't complete (because a device is still missing). This can lead to a subsequent "re-add" being recovered without any IO happening, which would result in loss of data. This patch takes the safe approach of not clearing bitmap bits if the array will still be degraded. This patch is suitable for all active -stable kernels.

Being able to write 'clean' to an 'array_state' of an inactive array to activate it in 'clean' mode is both unnecessary and inconvenient. It is unnecessary because the same can be achieved by writing 'active'. This activates and array, but it still remains 'clean' until the first write. It is inconvenient because writing 'clean' is more often used to cause an 'active' array to revert to 'clean' mode (thus blocking any writes until a 'write-pending' is promoted to 'active'). Allowing 'clean' to both activate an array and mark an active array as clean can lead to races: One program writes 'clean' to mark the active array as clean at the same time as another program writes 'inactive' to deactivate (stop) and active array. Depending on which writes first, the array could be deactivated and immediately reactivated which isn't what was desired. So just disable the use of 'clean' to activate an array. This avoids a race that can be triggered with mdadm-3.0 and external metadata, so it suitable for -stable.

The MOVW and MOVT are both load-immediate instructions, MOVW loads 16 bits into the bottom half of a register, and MOVT loads 16 bits into the top half of a register. The relocation information for these instructions has a full 32 bit value, plus an addend which is stored in the 16 immediate bits in the instruction itself. The immediate bits in the instruction are not contiguous (the register # splits it into a 4 bit and 12 bit value), so the addend has to be extracted accordingly and added to the value. The value is then split and put into the instruction; a MOVW uses the bottom 16 bits of the value, and a MOVT uses the top 16 bits.

And to make sure somebody can't just start from the same original seed of all-zeroes, and then do the "half_md4_transform()" over and over until they get the same sequence as the kernel has, each iteration also mixes in the same old "current->pid + jiffies" we used - so we should now have a regular strong pseudo-number generator, but we also have one that doesn't have a single seed. Note: the "pid + jiffies" is just meant to be a tiny tiny bit of noise. It has no real meaning. It could be anything. I just picked the previous seed, it's just that now we keep the state in between calls and that will feed into the next result, and that should make all the difference. I made that hash be a per-cpu data just to avoid cache-line ping-pong: having multiple CPU's write to the same data would be fine for randomness, and add yet another layer of chaos to it, but since get_random_int() is supposed to be a fast interface I did it that way instead. I considered using "__raw_get_cpu_var()" to avoid any preemption overhead while still getting the hash be _mostly_ ping-pong free, but in the end good taste won out.

This caused problems later when the consumer attempted to unmap the pages using the page-list (using the list addresses which were assumed to be still in CPU-endian order). Fix the mlx4 driver to allocate two buffers and use a private buffer for the hardware-format bus addresses. This patch fixes , an NFS/RDMA server crash. The cause of the crash was found by Vu Pham of Mellanox. The fix is along the lines suggested by Steve Wise in comment #21 in bug 1571.

The problem arises because fwmarks are stored in the 4th octet of a union nf_inet_addr .all, however in the case of IPv4 only the first octet, corresponding to .ip, is assigned and compared. In other words, using .all = { 0, 0, 0, htonl(svc->fwmark) always results in a value of 0 (32bits) being stored for IPv4. This means that one fwmark can be used, as it ends up being mapped to 0, but things break down when multiple fwmarks are used, as they all end up being mapped to 0. As fwmarks are 32bits a reasonable fix seems to be to just store the fwmark in .ip, and comparing and storing .ip when fwmarks are used. This patch makes the assumption that in calls to ip_vs_ct_in_get() and ip_vs_sched_persist() if the proto parameter is IPPROTO_IP then we are dealing with an fwmark. I believe this is valid as ip_vs_in() does fairly strict filtering on the protocol and IPPROTO_IP should not be used in these calls unless explicitly passed when making these calls for fwmarks in ip_vs_sched_persist().

Now all platform_driver is registered by platform_driver_register, which makes probe()/release()/... of platform_driver passed parameter of platform_device *, so platform driver can get platform_data from platform_device; 2. Other kind of devices do not need to use platform_data, we can decrease size of device if moving it to platform_device. Taking into consideration of thousands of files to be fixed and they can't be finished in one night(maybe it will take a long time), so we keep platform_data in device to allow two kind of cases coexist until all platform devices pass its platfrom data from platform_device->platform_data. All patches to do this kind of conversion are welcome. As we don't really want to do it, it was a bad idea.

It wouldn't cause corruption, but could cause decreased performance due to allocating a larger chunk of the journal (~ 27 blocks) than it would actually use. This patch loads the xattr root dentry at xattr initialization and creates it on-demand. Since we're using the cached dentry, there's no point in keeping lookup_or_create_dir around, so that's removed.

It did this by checking that the driver defined a method for the try_fmt handler for that buffer type. However, try_fmt is optional and a driver might not provide it even though it does support that type. So use g_fmt instead, since that isn't optional. This should fix a problem with VBI capture with saa7146.

In case the connection setup fails, hci_dev_put() is never called. Procedure to reproduce the issue: # hciconfig hci0 up # lsmod | grep btusb -> "used by" refcount = 1 # hcitool cc -> will get timeout # lsmod | grep btusb -> "used by" refcount = 2 # hciconfig hci0 down # lsmod | grep btusb -> "used by" refcount = 1 # rmmod btusb -> ERROR: Module btusb is in use The hci_dev_put() call got moved into del_conn() with the 2.6.25 kernel to fix an issue with hci_dev going away before hci_conn. However that change was wrong and introduced this problem. When calling hci_conn_del() it has to call hci_dev_put() after freeing the connection details. This handling should be fully symmetric. The execution of del_conn() is done in a work queue and needs it own calls to hci_dev_hold() and hci_dev_put() to ensure that the hci_dev stays until the connection cleanup has been finished.

If that happens then, the connection attempt will be canceled. This only applies to outgoing connections, but currently it can also be triggered by incoming connection. Don't call hci_acl_connect_cancel() on incoming connection since these have to be either accepted or rejected in this state. Once they are successfully connected they need to be fully disconnected anyway.

So it's not sufficient to ensure that you use phys_addr_t or uint64_t everywhere you handle physical addresses -- you also have to avoid using the construct 'addr & PAGE_MASK', because that will strip the high 32 bits of the address. This patch avoids that problem by using PHYSICAL_PAGE_MASK instead of PAGE_MASK where appropriate. It leaves '& PAGE_MASK' in a few instances that don't matter -- where it's being used on the virtual bus addresses we're dishing out, which are 32-bit anyway. Since PHYSICAL_PAGE_MASK is not present on other architectures, we have to define it (to PAGE_MASK) if it's not already defined. Maybe it would be better just to fix PAGE_MASK for i386/PAE?

This usually works well but if an error occurs during configuration stage, ata_dev_revalidate_and_attach() returns with error code and forgets new_mask. On the retry run, dev->class is set and new_mask for the device is clear, so the device just gets revalidated and thus ends up skipping post-configuration procedure including scheduling of SCSI_HOTPLUG for the device. When this occurs, ATA part of probing works fine but SCSI probing usually doesn't happen and makes the device unreachable. The behavior has been around for a very long time but it has been uncovered with the recent addition of 1_5_GBPS horkage which uses -EAGAIN return value from ata_dev_configure() to restart the probing sequence after forcing cable speed. This can be fixed by making sure dev->class is permanently set only after all configurations are successfully complete. Fix it.

For any *.text section, literals are placed in a corresponding *.literal section. The linker script (vmlinux.lds) must place these in the correct order. It must also combine them, when the *.text section can be larger than L32R's 256 kB range. For example, this doesn't work: *(.literal) *(.text) because L32R instructions at the end of .text can't reach the literals. The linker can solve this if they are combined in parentheses, like this: *(.literal .text) because it is now allowed mix literals in .text to bring them in range. None of this is done by standard vmlinux.lds.h macros such as TEXT_TEXT and INIT_TEXT. To avoid replicating the logic of that header file, we instead post-process the generated linker script to convert *(xxx.text) to *(xxx.literal xxx.text) for the following text sections: .text .ref.text .*init.text .*exit.text .text.* using a sed script. To do this we must override the default rule for vmlinux.lds (see scripts/Makefile.build and the top-level Makefile) to insert this extra step.

It checks bio->bi_idx against bio->bi_vcnt, but the subsequent code uses idx (which is, bio->bi_idx + next_idx) as the array index into bio_vec array. This means that the test really make sense only at the first iteration of !(nr_bytes >=bio->bi_size) case (when next_idx == zero). Fix this by replacing bio->bi_idx with idx.

This patch lets dma driver recognize if unmap_single or unmap_page should be used. It introduces two new dma control flags: DMA_COMPL_SRC_UNMAP_SINGLE and DMA_COMPL_DEST_UNMAP_SINGLE. They should be set to indicate dma driver to do dma-unmapping as single (first one for the source, tha latter for the destination). If respective flag is not set, the driver assumes dma-unmapping as page.

This would not be a problem except that hugetlbfs also provide a ->readpage implementation. As it exists, the core VM can assume the base page size is being used, allocate pages on behalf of the filesystem, insert them into the page cache and call ->readpage to populate them. These pages are the wrong size and at the wrong offset for hugetlbfs causing confusion. This patch deletes the ->readpage implementation for hugetlbfs on the grounds the core VM should not be allocating and populating pages on behalf of hugetlbfs. There should be no existing users of the ->readpage implementation so it should not cause a regression.

So we need to prepare for state changes *before* we register it. That means installing the eeepc-specific ACPI callback which handles the hotplug of the wireless network adaptor. This problem doesn't occur during normal operation. You have to 1) Boot with wireless enabled. eeepc-laptop should load automatically. 2) modprobe -r eeepc-laptop 3) modprobe eeepc-laptop On boot, the default rfkill state will be set to enabled. With the current core code, step 2) will disable the wireless. Therefore in step 3), the wireless will change state during registration, from disabled to enabled. But without this fix, the PCI device for the wireless adaptor will not appear.

This is easily detected. The RFKILL API states that in such cases, we should call rfkill_force_state() to notify the core. I have reported the bug to Asus. I believe this is the right thing to do for robustness, even if this particular firmware bug is fixed. 2) The same bug causes the wireless toggle key to be reported as 0x11 instead of 0x10. 0x11 is otherwise unused, so it should be safe to add this as a new keycode. The bug is triggered by removing the laptop battery while hibernated. On resume, the wireless toggle key causes the firmware to toggle the wireless state itself. (Also, the key is reported as 0x11 when the current wireless state is OFF). This is very poor behaviour because the OS can't predict whether the firmware is controlling the RFKILL state. Without this workaround, the bug means users have to press the wireless toggle key twice to enable, due to the OS/firmware conflict. (Assuming rfkill-input or equivalent is being used). The workaround avoids this. I believe that acpid scripts which toggle the value of the sysfs state file when the toggle key is pressed will be rendered ineffective by the bug, regardless of this workaround. If they simply toggle the state, when the firmware has already toggled it, then you will never see a state change. Tested on "EEEPC 4G" only.

SHE underclocks and undervolts the FSB and undervolts the CPU (at preset 2, "powersave"), or slightly overclocks the CPU (at preset 0, "performance"). Preset 1 is the default setting with default clocks and voltage. The new eeepc-laptop driver doesn't support it anymore. The attached patch adds support for it to eeepc-laptop.

When ext4_get_blocks_wrap() is called with create=1, the uninitialized extent is converted into an initialized one, so the BH_Unwritten flag is no longer appropriate.

In #20896 we found that vbetool clobbers the IER. In KMS mode this is particularly bad since we don't set the interrupt regs late (in EnterVT), so we'd fail to get *any* interrupts at all after X started (since some distros have scripts that call vbetool at X startup apparently). So this patch checks IER at wait_request time, and re-enables interrupts if it's been clobbered. In a proper config this check should never be triggered. This is really a distro issue, but having a sanity check is nice, as long as it doesn't have a real performance hit.

With kernel mode-setting, this becomes a problem, and makes native resolution boot go haywire -- for example, my Dell Studio Hybrid, hooked to a 1920x1080 display claims to have a 1024x768 LVDS, and the resulting graphical boot on the 1920x1080 display uses only the top left 1024x768, and auto-configured X will end up only 1024x768 as well. With this change, graphical boot and X both do 1920x1080 as expected. Note that we're simply embracing and extending the early bail-out code in place for the Mac Mini here. The xorg intel driver uses pci subsystem device and vendor id for matching, while we're using dmi lookups here. The MSI addition is courtesy of and tested by Bill Nottingham.

One of the "operations" that the device indicates is "queue a packet and update the window start". When the queue is empty, this is equivalent to "deliver the packet and update the window start". That case was optimized in i2400m_roq_queue_update_ws() so that we would not pointlessly queue and dequeue a packet. However, when the optimization was active, it wasn't updating the window start. That caused the reorder management code to get confused later on with what seemed to be wrong reorder requests from the device. Thus the fix implemented is to do the right thing and update the window start in both cases, when the queue is empty (and the optimization is done) and when not.

Background ---------- The performance monitor unit of the 64-bit POWER processor family has the ability to collect accurate instruction-level samples when profiling on marked events (i.e., "PM_MRK_"). In processors prior to POWER6, the MMCRA register contained "slot information" that the oprofile kernel driver used to adjust the value latched in the SIAR at the time of a PMU interrupt. But as of POWER6, these slot bits in MMCRA are no longer necessary for oprofile to use, since the SIAR itself holds the accurate sampled instruction address. With POWER6, these MMCRA slot bits were zero'ed out by hardware so oprofile's use of these slot bits was, in effect, a NOP. But with POWER7, these bits are no longer zero'ed out; however, they serve some other purpose rather than slot information. Thus, using these bits on POWER7 to adjust the SIAR value results in samples being attributed to the wrong instructions. The attached patch changes the oprofile kernel driver to ignore these slot bits on all newer processors starting with POWER6.

However, for a number of mpic implementations we have no isu (thus pass in 0) and will end up with a no linear map (size = 0). This causes us to always call irq_find_mapping() from mpic_get_irq(). By moving the allocation of the host map to after we've determined the number of sources we can actually benefit from having a linear map for the non-isu users that covers all the interrupt sources.

First, historically, we don't allocate the ROM resource in the resource tree. I'm not entirely certain of why, I susepct they often contained garbage on x86 but it's hard to tell. This causes the current generic code to always call pci_assign_resource() when trying to access the said ROM from sysfs, which will try to re-assign some new address regardless of what the ROM BAR was already set to at boot time. This can be a problem on hypervisor platforms like pSeries where we aren't supposed to move PCI devices around (and in fact probably can't). Second, our code that generates the PCI tree from the OF device-tree (instead of doing config space probing) which we mostly use on pseries at the moment, didn't set the (new) flag IORESOURCE_SIZEALIGN on any resource. That means that any attempt at re-assigning such a resource with pci_assign_resource() would fail due to resource_alignment() returning 0. This fixes this by doing these two things: - The code that calculates resource flags based on the OF device-node is improved to set IORESOURCE_SIZEALIGN on any valid BAR, and while at it also set IORESOURCE_READONLY for ROMs since we were lacking that too - We now allocate ROM resources as part of the resource tree. However to limit the chances of nasty conflicts due to busted firmwares, we only do it on the second pass of our two-passes allocation scheme, so that all valid and enabled BARs get precedence. This brings pSeries back the ability to access PCI ROMs via sysfs (and thus initialize various video cards from X etc...).

Work is progressing to switch away from pdflush as the process backing for flushing out dirty data. So it seems pointless to add more knobs to control pdflush threads. The original author of the patch did not have any specific use cases for adding the knobs, so we can easily revert this before 2.6.30 to avoid having to maintain this API forever.

The solution is to move the intel fb sysrq over to V for video instead of G for graphics. The SMP VOYAGER code to register for the sysrq-v is not anywhere to be found in the mainline kernel, so the comments in the code were cleaned up as well. This patch also cleans up the sysrq definitions for kgdb to make it generic for the kernel debugger, such that the sysrq 'g' can be used in the future to enter a gdbstub or another kernel debugger.

This could potentially cause the wrong location on disk to be read or written to, including potentially causing the corruption of the block group descriptors and/or inode table. This bug has been in the ext4 code since almost the very beginning of ext4's development. Fortunately once the data is stored in the page cache cache, ext4_get_blocks() doesn't need to be called, so trying to replicate this problem to the point where we could identify its root cause was *extremely* difficult. Many thanks to Kevin Shanahan for working over several months to be able to reproduce this easily so we could finally nail down the cause of the corruption.

The same can happen for iscsi when transitioning from logged in to failed and blocking the sdevs. This patch converts iscsi and fc's transitions back to use DID_IMM_RETRY instead of DID_TRANSPORT_DISRUPTED which has a limited number of retries that we do not want to use for handling this race.

It appears that the hit is entirely due to the paravirtualized spinlocks introduced by: | commit 8efcbab674de2bee45a2e4cdf97de16b8e609ac8 | Date: Mon Jul 7 12:07:51 2008 -0700 | | paravirt: introduce a "lock-byte" spinlock implementation The extra call/return in the spinlock path is somehow causing an increase in the cycles/instruction of somewhere around 2-7% (seems to vary quite a lot from test to test). The working theory is that the CPU's pipeline is getting upset about the call->call->locked-op->return->return, and seems to be failing to speculate (though I haven't seen anything definitive about the precise reasons). This doesn't entirely make sense, because the performance hit is also visible on unlock and other operations which don't involve locked instructions. But spinlock operations clearly swamp all the other pvops operations, even though I can't imagine that they're nearly as common (there's only a .05% increase in instructions executed). If I disable just the pv-spinlock calls, my tests show that pvops is identical to non-pvops performance on native (my measurements show that it is actually about .1% faster, but Xiaohui shows a .05% slowdown). Summary of results, averaging 10 runs of the "mmperf" test, using a no-pvops build as baseline: nopv Pv-nospin Pv-spin CPU cycles 100.00% 99.89% 102.18% instructions 100.00% 100.10% 100.15% CPI 100.00% 99.79% 102.03% cache ref 100.00% 100.84% 100.28% cache miss 100.00% 90.47% 88.56% cache miss rate 100.00% 89.72% 88.31% branches 100.00% 99.93% 100.04% branch miss 100.00% 103.66% 107.72% branch miss rt 100.00% 103.73% 107.67% wallclock 100.00% 99.90% 102.20% The clear effect here is that the 2% increase in CPI is directly reflected in the final wallclock time. (The other interesting effect is that the more ops are out of line calls via pvops, the lower the cache access and miss rates. Not too surprising, but it suggests that the non-pvops kernel is over-inlined. On the flipside, the branch misses go up correspondingly...) So, what's the fix? Paravirt patching turns all the pvops calls into direct calls, so _spin_lock etc do end up having direct calls. For example, the compiler generated code for paravirtualized _spin_lock is: <_spin_lock+0>: mov %gs:0xb4c8,%rax <_spin_lock+9>: incl 0xffffffffffffe044(%rax) <_spin_lock+15>: callq *0xffffffff805a5b30 <_spin_lock+22>: retq The indirect call will get patched to: <_spin_lock+0>: mov %gs:0xb4c8,%rax <_spin_lock+9>: incl 0xffffffffffffe044(%rax) <_spin_lock+15>: callq <__ticket_spin_lock> <_spin_lock+20>: nop; nop /* or whatever 2-byte nop */ <_spin_lock+22>: retq One possibility is to inline _spin_lock, etc, when building an optimised kernel (ie, when there's no spinlock/preempt instrumentation/debugging enabled). That will remove the outer call/return pair, returning the instruction stream to a single call/return, which will presumably execute the same as the non-pvops case. The downsides arel 1) it will replicate the preempt_disable/enable code at eack lock/unlock callsite; this code is fairly small, but not nothing; and 2) the spinlock definitions are already a very heavily tangled mass of #ifdefs and other preprocessor magic, and making any changes will be non-trivial. The other obvious answer is to disable pv-spinlocks. Making them a separate config option is fairly easy, and it would be trivial to enable them only when Xen is enabled (as the only non-default user). But it doesn't really address the common case of a distro build which is going to have Xen support enabled, and leaves the open question of whether the native performance cost of pv-spinlocks is worth the performance improvement on a loaded Xen system (10% saving of overall system CPU when guests block rather than spin). Still it is a reasonable short-term workaround.

The uarts available in the ep93xx have individual clock controls. The current implementation assumes that the bootloader has enabled the clocks before the kernel has booted. It also assumes that the bootloader has set the UARTBAUD bit indicating that the uarts are running off the 14.7456MHz external crystal. This fixes both issues. It also allows the uart clocks to be stopped when there are no users.

Fix this by splitting up the warn_slowpath_null/fmt cases differently, using a common helper function, and getting the return address in the right place. This also happens to avoid the unnecessary stack usage for the non-stdargs case, and just generally cleans things up. Make the function name printout use %pS while at it.

This was discovered on my x86 boxes. The issue is that gcc used the same register for an output as it did for an input in an asm statement. I first thought this was a bug in gcc and reported it. I was notified that gcc was correct and that the output had to be flagged as an "early clobber". I noticed that powerpc had the same issue and this patch fixes it.

In FLATMEM, it is expected that holes always have valid memmap as long as there is valid PFNs either side of the hole. In SPARSEMEM, it is assumed that a valid section has a memmap for the entire section. However, ARM and maybe other embedded architectures in the future free memmap backing holes to save memory on the assumption the memmap is never used. The page_zone linkages are then broken even though pfn_valid() returns true. A walker of the full memmap must then do this additional check to ensure the memmap they are looking at is sane by making sure the zone and PFN linkages are still valid. This is expensive, but walkers of the full memmap are extremely rare. This was caught before for FLATMEM and hacked around but it hits again for SPARSEMEM because the page_zone linkages can look ok where the PFN linkages are totally screwed. This looks like a hatchet job but the reality is that any clean solution would end up consumning all the memory saved by punching these unexpected holes in the memmap. For example, we tried marking the memmap within the section invalid but the section size exceeds the size of the hole in most cases so pfn_valid() starts returning false where valid memmap exists. Shrinking the size of the section would increase memory consumption offsetting the gains. This patch identifies when an architecture is punching unexpected holes in the memmap that the memory model cannot automatically detect and sets ARCH_HAS_HOLES_MEMORYMODEL. At the moment, this is restricted to EP93xx which is the model sub-architecture this has been reported on but may expand later. When set, walkers of the full memmap must call memmap_valid_within() for each PFN and passing in what it expects the page and zone to be for that PFN. If it finds the linkages to be broken, it assumes the memmap is invalid for that PFN.

That's all very well, but ftdi_sio_port_remove() still contains a call to usb_set_serial_port_data(port, NULL) -- so by the time we get to ftdi_close() for the port which was unplugged, it _still_ oopses on dereferencing that NULL pointer, as it did before (and does in 2.6.29). The fix is just not to clear the private data in ftdi_sio_port_remove(). Then the refcount is properly reduced to zero when the final kref_put() happens in ftdi_close(). Remove a bogus comment too, while we're at it. And stop doing things inside "if (priv)" -- it must _always_ be there. Based loosely on an earlier patch by Daniel Mack, and suggestions by Alan Stern.

It also includes a fix for a bogus NULL pointer check in CIFSSMBQueryUnixSymLink that Jeff Moyer spotted. It's possible for CIFSSMBQueryUnixSymLink to return without setting target_path to a valid pointer. If that happens then the current value to which we're initializing this pointer could cause an oops when it's kfree'd. This patch is a little more comprehensive than the last patches. It reorganizes cifs_follow_link a bit for (hopefully) better readability. It should also eliminate the uneeded allocation of full_path on servers without unix extensions (assuming they can get to this point anyway, of which I'm not convinced). On a side note, I'm not sure I agree with the logic of enabling this query even when unix extensions are disabled on the client. It seems like that should disable this as well. But, changing that is outside the scope of this fix, so I've left it alone for now.

This is nice and fast, but won't work well if memory is fragmented, since the slab allocator works with physically contiguous memory (i.e. order > 2 allocations are likely to fail fairly early after booting and doing some work). This patch works around the issue by falling back to vmalloc for >PAGE_SIZE allocations. This is ugly, but much less work than chaining a bunch of pages together by hand (suprisingly there's not a bunch of generic kernel helpers for this yet afaik). vmalloc space is somewhat precious on 32 bit kernels, but our allocations shouldn't be big enough to cause problems, though they're routinely more than a page. Note that this patch doesn't address the unchecked alloc-based-on-ioctl-args in GEM; that needs to be fixed in a separate patch. Also, I've deliberately ignored the DRM's "area" junk. I don't think anyone actually uses it anymore and I'm hoping it gets ripped out soon. [Updated: removed size arg to new free function. We could unify the free functions as well once the DRM mem tracking is ripped out.] fd.o bug #20152 (part 1/3) Signed-off-by: Jesse Barnes Signed-off-by: Eric Anholt --- drivers/gpu/drm/i915/i915_gem.c | 38 +++++++++++++++----------------------- include/drm/drmP.h | 24 ++++++++++++++++++++++++ 2 files changed, 39 insertions(+), 23 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_gem.c b/drivers/gpu/drm/i915/i915_gem.c index b189b49c760..4a24c90fb94 100644 --- a/drivers/gpu/drm/i915/i915_gem.c +++ b/drivers/gpu/drm/i915/i915_gem.c @@ -349,7 +349,7 @@ i915_gem_shmem_pread_slow(struct drm_device *dev, struct drm_gem_object *obj, last_data_page = (data_ptr + args->size - 1) / PAGE_SIZE;

The eventual fault was fixed up by futex_handle_fault() which walked the VMA with mmap_sem held. After the cleanup patches which removed the mmap_sem dependency of the futex code commit 4dc5b7a36a49eff97050894cf1b3a9a02523717 (futex: clean up fault logic) removed the private VMA walk logic from the futex code. This change results in a stale RO mapping which is not fixed up. Instead of reintroducing the previous fault logic we set up the mapping in get_user_pages_fast() read/write for all operations which modify user space data. Also handle private futexes in the same way and make the current unconditional access_ok(VERIFY_WRITE) depend on the futex op.

Wysocki" Date: Sun, 17 May 2009 20:17:06 +0200 Subject: PCI PM: Fix initialization and kexec breakage for some devices Recent PCI PM changes introduced a bug that causes some devices to be mishandled after kexec and during early initialization. The failure scenario in the kexec case is the following: * Assume a PCI device is not power-manageable by the platform and has PCI_PM_CTRL_NO_SOFT_RESET set in PMCSR. * The device is put into D3 before kexec (using the native PCI PM). * After kexec, pci_setup_device() sets the device's power state to PCI_UNKNOWN. * pci_set_power_state(dev, PCI_D0) is called by the device's driver. * __pci_start_power_transition(dev, PCI_D0) is called and since the device is not power-manageable by the platform, it causes pci_update_current_state(dev, PCI_D0) to be called. As a result the device's current_state field is updated to PCI_D3, in accordance with the contents of its PCI PM registers. * pci_raw_set_power_state() is called and it changes the device power state to D0. *However*, it should also call pci_restore_bars() to reinitialize the device, but it doesn't, because the device's current_state field has been modified earlier. To prevent this from happening, modify pci_platform_power_transition() so that it doesn't use pci_update_current_state() to update the current_state field for devices that aren't power-manageable by the platform. Instead, this field should be updated directly for devices that don't support the native PCI PM. Signed-off-by: Rafael J.

It fills the buffer 2 bytes at a time. What the code doesn't take into account is that sprintf(buf, "%02x", data) actually writes 3 bytes. 2 bytes for the data and then it nul terminates the string. Since we declare buf to be 40 characters long and then we write 40 bytes of data into buf sprintf is going to write 41 characters. The fix is to leave room in buf for the nul terminator.

This breaks for example on PowerPC with 64K pages and radeon despite the kernel radeon actually doing the right rouding in the first place. The way SAREA_MAX is defined with a bunch of ifdef's and duplicated between libdrm and the X server is gross, ultimately it should be retrieved by userspace from the kernel, but in the meantime, we have plenty of existing userspace built with bad values that need to work. This patch works around broken userspace by rounding the requested size in drm_addmap_core() of any SHM map to the page size. Since the backing memory for SHM maps is also allocated within addmap_core, there is no danger of adjacent memory being exposed due to the increased map size. The only side effect is that drivers that previously tried to create or access SHM maps using a size < PAGE_SIZE and failed (getting -EINVAL), will now succeed at the cost of a little bit more memory used if that happens to be when the map is created.

Therefore, we have this layout: extra: +-------------------------+ | struct iw_encode_ext { | | ... | | u16 key_len; | | u8 key[0]; | | }; | +-------------------------+ | key material | +-------------------------+ Now, all drivers I checked use ext->key_len without checking that both key_len and the struct fit into the extra buffer that has been copied from userspace. This leads to a buffer overrun while reading that buffer, depending on the driver it may be possible to specify arbitrary key_len or it may need to be a proper length for the key algorithm specified. Thankfully, this is only exploitable by root, but root can actually cause a segfault or use kernel memory as a key (which you can even get back with siocgiwencode or siocgiwencodeext from the key buffer). Fix this by verifying that key_len fits into the buffer along with struct iw_encode_ext. Signed-off-by: Johannes Berg Signed-off-by: John W.

As explained by Johannes Berg A - lock T - timer phase CPU 1 CPU 2 --------------------------------------------- some place that calls cancel_timer_sync() (which is the | code) lock-irq(A) | "lock-irq"(T) | "unlock"(T) | wait(T) unlock(A) timer softirq "lock"(T) run(T) "unlock"(T) irq handler lock(A) unlock(A) Now all that again, interleaved, leading to deadlock: lock-irq(A) "lock"(T) run(T) IRQ during or maybe before run(T) --> lock(A) "lock-irq"(T) wait(T) We fix this by moving the call to cancel_delayed_work() into workqueue. There are cases where the work may not actually be queued or running at the time we are trying to cancel it, but cancel_delayed_work() is able to deal with this. Also cleanup iwl_set_mode related to this call. This function (iwl_set_mode) is only called when bringing interface up and there will thus not be any scanning done. No need to try to cancel scanning.

Lukyanov found a regression in 2.6.29 and made a complete analysis found in http://bugzilla.kernel.org/show_bug.cgi?id=13339 Quoted here because its a perfect one : begin_of_quotation 2.6.29 patch has introduced flexible route cache rebuilding. Unfortunately the patch has at least one critical flaw, and another problem. rt_intern_hash calculates rthi pointer, which is later used for new entry insertion. The same loop calculates cand pointer which is used to clean the list. If the pointers are the same, rtable leak occurs, as first the cand is removed then the new entry is appended to it. This leak leads to unregister_netdevice problem (usage count > 0). Another problem of the patch is that it tries to insert the entries in certain order, to facilitate counting of entries distinct by all but QoS parameters. Unfortunately, referencing an existing rtable entry moves it to list beginning, to speed up further lookups, so the carefully built order is destroyed. For the first problem the simplest patch it to set rthi=0 when rthi==cand, but it will also destroy the ordering. end_of_quotation Problematic commit is 1080d709fb9d8cd4392f93476ee46a9d6ea05a5b (net: implement emergency route cache rebulds when gc_elasticity is exceeded) Trying to keep dst_entries ordered is too complex and breaks the fact that order should depend on the frequency of use for garbage collection. A possible fix is to make rt_intern_hash() simpler, and only makes rt_check_expire() a litle bit smarter, being able to cope with an arbitrary entries order. The added loop is running on cache hot data, while cpu is prefetching next object, so should be unnoticied. Reported-and-analyzed-by: Alexander V.

For that to happen, the device has to have negotiated with the basestation to put the link on IDLE state. If the host tries to put the device in standby while it is connected but not idle, the device resets, as the driver should not do that. To avoid triggering that, when the USB susbsytem requires the driver to autosuspend the device, the driver checks if the device is not yet idle. If it is not, the request is rejected (will be retried again later on after the autosuspend timeout). At some point the device will enter idle and the request will succeed (unless of course, there is network traffic, but at that point, there is no idle neither in the link or the host interface).

When fsl_dma_tx_submit() is run, it only assigns a cookie to the first descriptor. All of the remaining descriptors keep their original value, including the last descriptor, which is set to -EBUSY. After the DMA completes, the driver will update the last completed cookie to be -EBUSY, which is an error code instead of a valid cookie. This causes dma_async_is_complete() to always return DMA_IN_PROGRESS. This causes the fsldma driver to never cleanup the queue of link descriptors, and the driver will re-run the DMA transaction on the hardware each time it receives the End-of-Chain interrupt. This causes an infinite loop. With this patch, fsl_dma_tx_submit() is changed to assign a cookie to every descriptor in the chain. The rest of the code then works without problems.

Peter Anvin" Date: Thu, 21 May 2009 11:46:16 -0700 Subject: x86, setup: revert ACPI 3 E820 extended attributes support Remove ACPI 3 E820 extended memory attributes support. At least one vendor actively set all the flags to zero, but left ECX on return at 24. This bug may be present in other BIOSes. The breakage functionally means the ACPI 3 flags are probably completely useless, and that no OS any time soon is going to rely on their existence. Therefore, drop support completely. We may want to revisit this question in the future, if we find ourselves actually needing the flags. This reverts all or part of the following checkins: cd670599b7b00d9263f6f11a05c0edeb9cbedaf3 c549e71d073a6e9a4847497344db28a784061455 However, retain the part from the latter commit that copies e820 into a temporary buffer; that is an unrelated BIOS workaround. Put in a comment to explain that part. See https://bugzilla.redhat.com/show_bug.cgi?id=499396 for some additional information.

As the connector type_id is coupled to the connector type, the connector type cannot simply be modified on an initialised connector. This patch changes the order of operations on intel_sdvo_init so that the type is determined before the connector is intialised. This fixes a bug whereby the name card0-VGA-1 would be allocted to both a CRT and an SDVO connector since the SDVO connector would be initialised with type 'unknown' and hence have its type_id assigned from the wrong pool.

Previously, we would set the control bus switch before calls were made to request EDID information over DDC. But recently the DDC code started doing multiple I2C transfers to get the EDID extensions as well. This tripped up SDVO, because the control bus switch is only in effect until the next STOP after a START. By doing our own algo, we can wrap each i2c transaction on the DDC I2C bus with the control bus switch it requires. freedesktop.org bug #21042 Signed-off-by: Ma Ling [anholt: Hand application for conflict, fixed error path] Signed-off-by: Eric Anholt --- drivers/gpu/drm/i915/intel_sdvo.c | 67 ++++++++++++++++++++++++++++++++++++--- 1 file changed, 63 insertions(+), 4 deletions(-) diff --git a/drivers/gpu/drm/i915/intel_sdvo.c b/drivers/gpu/drm/i915/intel_sdvo.c index ded122c1ae2..f3ef6bfd8ff 100644 --- a/drivers/gpu/drm/i915/intel_sdvo.c +++ b/drivers/gpu/drm/i915/intel_sdvo.c @@ -1402,10 +1402,8 @@ static enum drm_connector_status intel_sdvo_detect(struct drm_connector *connect static void intel_sdvo_get_ddc_modes(struct drm_connector *connector) { struct intel_output *intel_output = to_intel_output(connector); - struct intel_sdvo_priv *sdvo_priv = intel_output->dev_priv; /* set the bus switch and get the modes */ - intel_sdvo_set_control_bus_switch(intel_output, sdvo_priv->ddc_bus); intel_ddc_get_modes(intel_output); #if 0 @@ -1601,6 +1599,9 @@ static void intel_sdvo_destroy(struct drm_connector *connector) if (intel_output->i2c_bus) intel_i2c_destroy(intel_output->i2c_bus); + if (intel_output->ddc_bus) + intel_i2c_destroy(intel_output->ddc_bus); + drm_sysfs_connector_remove(connector); drm_connector_cleanup(connector); kfree(intel_output); @@ -1697,12 +1698,56 @@ intel_sdvo_get_digital_encoding_mode(struct intel_output *output) return true; } +static struct intel_output * +intel_sdvo_chan_to_intel_output(struct intel_i2c_chan *chan) +{ + struct drm_device *dev = chan->drm_dev; + struct drm_connector *connector; + struct intel_output *intel_output = NULL; + + list_for_each_entry(connector, + &dev->mode_config.connector_list, head) { + if (to_intel_output(connector)->ddc_bus == chan) { + intel_output = to_intel_output(connector); + break; + } + } + return intel_output; +} + +static int intel_sdvo_master_xfer(struct i2c_adapter *i2c_adap, + struct i2c_msg msgs[], int num) +{ + struct intel_output *intel_output; + struct intel_sdvo_priv *sdvo_priv; + struct i2c_algo_bit_data *algo_data; + struct i2c_algorithm *algo; + + algo_data = (struct i2c_algo_bit_data *)i2c_adap->algo_data; + intel_output = + intel_sdvo_chan_to_intel_output( + (struct intel_i2c_chan *)(algo_data->data)); + if (intel_output == NULL) + return -EINVAL; + + sdvo_priv = intel_output->dev_priv; + algo = (struct i2c_algorithm *)intel_output->i2c_bus->adapter.algo; + + intel_sdvo_set_control_bus_switch(intel_output, sdvo_priv->ddc_bus); + return algo->master_xfer(i2c_adap, msgs, num); +} + +static struct i2c_algorithm intel_sdvo_i2c_bit_algo = { + .master_xfer = intel_sdvo_master_xfer, +}; + bool intel_sdvo_init(struct drm_device *dev, int output_device) { struct drm_connector *connector; struct intel_output *intel_output; struct intel_sdvo_priv *sdvo_priv; struct intel_i2c_chan *i2cbus = NULL; + struct intel_i2c_chan *ddcbus = NULL; int connector_type; u8 ch[0x40]; int i; @@ -1748,6 +1793,20 @@ bool intel_sdvo_init(struct drm_device *dev, int output_device) } } + /* setup the DDC bus. */ + if (output_device == SDVOB) + ddcbus = intel_i2c_create(dev, GPIOE, "SDVOB DDC BUS"); + else + ddcbus = intel_i2c_create(dev, GPIOE, "SDVOC DDC BUS"); + + if (ddcbus == NULL) + goto err_i2c; + + intel_sdvo_i2c_bit_algo.functionality = + intel_output->i2c_bus->adapter.algo->functionality; + ddcbus->adapter.algo = &intel_sdvo_i2c_bit_algo; + intel_output->ddc_bus = ddcbus; + /* In defaut case sdvo lvds is false */ sdvo_priv->is_lvds = false; intel_sdvo_get_capabilities(intel_output, &sdvo_priv->caps); @@ -1862,11 +1921,11 @@ bool intel_sdvo_init(struct drm_device *dev, int output_device) sdvo_priv->caps.output_flags & (SDVO_OUTPUT_TMDS1 | SDVO_OUTPUT_RGB1) ?

After discussion yesteday on samba-technical about the posix lookup regression, and looking at a problem with cifs posix open to one particular Samba version, Jeff and JRA realized that Samba server's behavior changed in this area (posix open behavior on files vs. directories). To make this behavior consistent, JRA just made a fix to Samba server to alter how it handles open of directories (now returning the equivalent of EISDIR instead of success). Since we don't know at lookup time whether the inode is a directory or file (and thus whether posix open will succeed with most current Samba server), this change avoids the posix open code on lookup open (just issues posix open on creates). This gets the semantic benefits we want (atomicity, posix byte range locks, improved write semantics on newly created files) and file create still is fast, and we avoid the problem that Jeff noticed yesterday with "openat" (and some open directory calls) of non-cached directories to one version of Samba server, and will work with future Samba versions (which include the fix jra just pushed into Samba server). I confirmed this approach with jra yesterday and with Shirish today. Posix open is only called (at lookup time) for file create now. For opens (rather than creates), because we do not know if it is a file or directory yet, and current Samba no longer allows us to do posix open on dirs, we could end up wasting an open call on what turns out to be a dir. For file opens, we wait to call posix open till cifs_open. It could be added here (lookup) in the future but the performance tradeoff of the extra network request when EISDIR or EACCES is returned would have to be weighed against the 50% reduction in network traffic in the other paths.

This will cause lowest_running() to return the cookie of the first entry on the async_pending list, which might be nothing at all to do with the domain being asked for and thus cause the domain synchronization to wait for an unrelated domain. This can cause a deadlock if domain synchronization is used from one domain to wait for another.

Please read the following threads for more information: http://thread.gmane.org/gmane.linux.kernel/835783 The following is the proposed fix which teaches pageattr about percpu aliases. http://thread.gmane.org/gmane.linux.kernel/837157 However, the above changes are deemed too pervasive for upstream inclusion for 2.6.30 release, so this patch essentially disables the remap allocator for the time being.

The RXBUF_ALIGNMENT realignment done in gfar_new_skb() will be done twice on skbuffs recycled in this way, causing there not to be enough room in the skb anymore to receive a full packet, eventually leading to an skb_over_panic from gfar_clean_rx_ring() -> skb_put(). Resetting the skb->data pointer to skb->head + NET_SKB_PAD before putting the skb back onto the recycle list restores the mentioned invariant, and should fix this issue.

Thus the conntrack entry is destroyed but the destination retransmits data until timeout. The same technique, i.e. sending properly crafted RST segments, can easily be used to bypass connlimit/connbytes based restrictions (the sample script written by Robert can be found in the netfilter mailing list archives). The patch below adds a new flag and new field to struct ip_ct_tcp_state so that checking RST segments can be made more strict and thus TCP conntrack can catch the invalid ones: the RST segment is accepted only if its sequence number higher than or equal to the highest ack we seen from the other direction. (The last_ack field cannot be reused because it is used to catch resent packets.)

Linux relies on this behaviour when zapping the low mappings of PAE kernels during boot. The code already handled changes to CR4.PAE; augment it to also notice changes to PSE and PGE. This triggered while booting an F11 PAE kernel; the futex initialization code runs before any CR3 reloads and writes to a NULL pointer; the futex subsystem ended up uninitialized, killing PI futexes and pulseaudio which uses them.

The kernel image is one statically linked object and only uses two relocation types - R_386_PC32 and R_386_32, of the two only the latter needs massaging during kernel relocation and thus handled by relocs. R_386_PC32 is ignored and all other relocation types are considered error. When the target of a relocation resides in a discarded section, binutils doesn't throw away the relocation record but nullifies it by changing it to R_386_NONE, which unfortunately makes relocs fail. The problem was triggered by yet out-of-tree x86 stack unwind patches but given the binutils behavior, ignoring R_386_NONE is the right thing to do. The problem has been tracked down to binutils behavior by Jan Beulich.

If not all of the active events are acknowledged, or a new event becomes active while the existing ones are cleared in the handler, we will not see a new interrupt. The current interrupt handler masks off the Rx and Tx events once the NAPI handler has been scheduled, which opens a race window in which we can get another Rx or Tx event and never ACK'ing it, stopping all activity until the link is reset (ifconfig down/up).

The rwlock seems to be taken around the whole call to cpufreq_governor_dbs(), when it should be only taken around accesses to the locked data, and especially *not* around the call to dbs_timer_exit(). Reverting my fix attempt would put the teardown race back in place (replacing the cancel_delayed_work_sync by cancel_delayed_work). Instead, a proper fix would imply modifying this critical section : cpufreq.c: __cpufreq_remove_dev() ... if (cpufreq_driver->target) __cpufreq_governor(data, CPUFREQ_GOV_STOP); unlock_policy_rwsem_write(cpu); To make sure the __cpufreq_governor() callback is not called with rwsem held. This would allow execution of cancel_delayed_work_sync() without being nested within the rwsem. Applies on top of the 2.6.30-rc5 tree. Required to remove circular dep in teardown of both conservative and ondemande governors so they can use cancel_delayed_work_sync(). CPUFREQ_GOV_STOP does not modify the policy, therefore this locking seemed unneeded. Signed-off-by: Mathieu Desnoyers CC: KOSAKI Motohiro Cc: Greg KH CC: Ingo Molnar CC: "Rafael J.

Currently powernow-k8 determines CPU frequency from ACPI PSS objects, but according to AMD family 11h BKDG this frequency is just a rounded value: "CoreFreq (MHz) = The CPU COF specified by MSRC001_00[6B:64][CpuFid] rounded to the nearest 100 Mhz." As a consequnce powernow-k8 reports wrong CPU frequency on some systems, e.g. on Turion X2 Ultra: powernow-k8: Found 1 AMD Turion(tm)X2 Ultra DualCore Mobile ZM-82 processors (2 cpu cores) (version 2.20.00) powernow-k8: 0 : pstate 0 (2200 MHz) powernow-k8: 1 : pstate 1 (1100 MHz) powernow-k8: 2 : pstate 2 (600 MHz) But this is wrong as frequency for Pstate2 is 550 MHz. x86info reports it correctly: #x86info -a |grep Pstate ... Pstate-0: fid=e, did=0, vid=24 (2200MHz) Pstate-1: fid=e, did=1, vid=30 (1100MHz) Pstate-2: fid=e, did=2, vid=3c (550MHz) (current) Solution is to determine the frequency directly from Pstate MSRs instead of using rounded values from ACPI table.

Additionally, we programmed that bad value into the register on 8xx, so the only pitch that would work correctly was 4096 (512-1023 pixels), while others would probably give bad rendering or hangs.

On the 865, but not the 855, the clflush we do appears to not actually make it out to the hardware all the time. An easy way to safely reproduce was X -retro, which would show that some of the blits involved in drawing the lovely root weave didn't make it out to the hardware. Those blits are 32 bytes each, and 1-2 would be missing at various points around the screen. Other experimentation (doing more clflush, doing more AGP chipset flush, poking at some more device registers to maybe trigger more flushing) didn't help. krh came up with the wbinvd as a way to successfully get all those blits to appear.

While it was a good idea to try to use the mm/vmalloc.c allocator instead of our own (in fact, ours is itself a dup on an old variant of the vmalloc one), unfortunately, the approach is terminally busted since dma_alloc_coherent() can be called at interrupt time or in atomic contexts and there's little chances we'll make the code in mm/vmalloc.c cope with\ that :-( Until we can get the generic code to forbid that idiocy and fix all drivers abusing it, we pretty much have no choice but revert to our custom virtual space allocator. There's also a problem with SMP safety since freeing such mapping would require an IPI which cannot be done at interrupt time. However, right now, I don't think we support any platform that is both SMP and has non-coherent DMA (don't laugh, I know such things do exist !) so we can sort that out later.

The implementation we just revived has issues, such as using a Kconfig-defined virtual address area in kernel space that nothing actually carves out (and thus will overlap whatever is there), or having some dependencies on being self contained in a single PTE page which adds unnecessary constraints on the kernel virtual address space. This fixes it by using more classic PTE accessors and automatically locating the area for consistent memory, carving an appropriate hole in the kernel virtual address space, leaving only the size of that area as a Kconfig option. It also brings some dma-mask related fixes from the ARM implementation which was almost identical initially but grew its own fixes.

In other words, if acpiphp has claimed a PCI device, and that device is logically removed, then acpiphp may oops when it attempts to access it again. # echo 1 > /sys/bus/pci/devices/$device/remove # echo 0 > /sys/bus/pci/slots/$slot/power Unable to handle kernel NULL pointer dereference (address 0000000000000000) Call Trace: [] show_stack+0x50/0xa0 [] show_regs+0x820/0x860 [] die+0x190/0x2a0 [] ia64_do_page_fault+0x8e0/0xa40 [] ia64_native_leave_kernel+0x0/0x270 [] pci_remove_bus_device+0x120/0x260 [] acpiphp_disable_slot+0x410/0x540 [acpiphp] [] disable_slot+0xc0/0x120 [acpiphp] [] power_write_file+0x1e0/0x2a0 [pci_hotplug] [] pci_slot_attr_store+0x60/0xa0 [] sysfs_write_file+0x230/0x2c0 [] vfs_write+0x190/0x2e0 [] sys_write+0x80/0x100 [] ia64_ret_from_syscall+0x0/0x20 [] __kernel_syscall_via_break+0x0/0x20 The root cause of this oops is that the logical remove ("echo 1 > /sys/bus/pci/devices/$device/remove") destroyed the pci_dev. The pci_dev struct itself wasn't deallocated because acpiphp kept a reference, but some of its fields became invalid. acpiphp doesn't have any real reason to keep a pointer to a pci_dev around. It can always derive it using pci_get_slot(). If a logical remove destroys the pci_dev, acpiphp won't find it and is thus prevented from causing mischief.

If the object is mmapped through the GTT it can still get evicted in this way by other objects requiring GTT space. When the GTT mapping is touched again we fault it back into the GTT, but fail to set it back to the GTT domain. This means we fail to flush any cached CPU writes to the pages backing the object which will then happen "eventually", typically after we write to the page through the uncached GTT mapping. [anholt: Note that userland does do a set_domain(GTT, GTT) when starting to access the GTT mapping. That covers getting the existing mapping of the object synchronized if it's bound to the GTT. But set_domain(GTT, GTT) doesn't do anything if the object is currently unbound.

The svcrdma module was incorrectly unmapping the RPCRDMA header page. On IBM pserver systems this causes a resource leak that results in running out of bus address space (10 cthon iterations will reproduce it). The code was mapping the full page but only unmapping the actual header length. The fix is to only map the header length. I also cleaned up the use of ib_dma_map_page() calls since the unmap logic always uses ib_dma_unmap_single(). I made these symmetrical.

Since operand lengths other than 32bit are required, the full implementations are only available if the ARMv6K extensions are present (for the LDREXB, LDREXH and LDREXD instructions). For ARMv6, only 32-bits cmpxchg is available. Mathieu : Make cmpxchg_local always available with best implementation for all type sizes (1, 2, 4 bytes). Make cmpxchg64_local always available. Use "Ir" constraint for "old" operand, like atomic.h atomic_cmpxchg does. Change since v3 : - Add "memory" clobbers (thanks to Nicolas Pitre) - removed __asmeq(), only needed for old compilers, very unlikely on ARMv6+. Note : ARMv7-M should eventually be ifdefed-out of cmpxchg64. But it's not supported by the Linux kernel currently. Put back arm < v6 cmpxchg support.

The isp1760_urb_dequeue function gets called, but the packet being dequeued is not necessarily at the front of one of the 32 queues. If not, the isp1760_urb_done function doesn't get called for the URB and the process trying to free it hangs forever on a wait_queue. This patch does two things. If the URB being dequeued has others queued behind it, it re-queues them. And it searches the queues looking for the URB being dequeued rather than just looking at the one at the front of the queue.

The usb-serial core then skips the step of registering the port devices; when the disconnect occurs, the attempt to unregister the ports fails dramatically. This problem shows up with Keyspan devices and it might affect others as well. When the attach method returns a positive value, the patch sets num_ports to 0. This tells usb_serial_disconnect() not to try unregistering any of the ports; instead they are cleaned up by destroy_serial().

Replace that build-time scheme with a load-time module parameter: "7300_idle.forceload=1" to make it easier to test the driver on hardware that while not officially validated, works fine and is much more commonly available. By default (no modparam) the driver will continue to load only on the i7300. Note that ioat_dma runs a copy of i7300_idle's probe routine to know to reserve an IOAT channel for i7300_idle. This change makes ioat_dma do that always on the i5000, just like it does on the i7300.

Rx descriptors are fed with the a page buffer bus address + page chunk offset. The page buffer bus address is set and retrieved through pci_unamp_addr_set(), pci_unmap_addr(). These functions being meaningless on x86 (if CONFIG_DMA_API_DEBUG is not set). The HW ends up with a bogus bus address. This patch saves the page buffer bus address for all plaftorms.

- re-initialization of host->col_addr which is used as byte index between the successive READID flash commands. - compile error when CONFIG_PM is enabled - pass on the error code from clk_get() - return -ENOMEM in case of failed ioremap() - pass on the return value of platform_driver_probe() directly - remove excessive printk - let command line partition table parsing with mxc_nand name.

However, on the Xtensa S6000 we have registers up to 128bit width which can be used from userspace and therefor need userspace stack and data-section alignment of at least this size. This patch drops flat_stack_align() and uses the same alignment that is required for slab caches, ARCH_SLAB_MINALIGN, or wordsize if it's not defined by the architecture. It also fixes m32r which was obviously kaput, aligning an uninitialized stack entry instead of the stack pointer.

As part of this, page_table_shareable() checks a pair of vma->vm_flags and they must match if they are to be shared. All VMA flags are taken into account, including VM_LOCKED. The problem is that VM_LOCKED is cleared on fork(). When a process with a shared memory segment forks() to exec() a helper, there will be shared VMAs with different flags. The impact is that the shared segment is sometimes considered shareable and other times not, depending on what process is checking. What happens is that the segment page tables are being shared but the count is inaccurate depending on the ordering of events. As the page tables are freed with put_page(), bad pmd's are found when some of the children exit. The hugepage counters also get corrupted and the Total and Free count will no longer match even when all the hugepage-backed regions are freed. This requires a reboot of the machine to "fix". This patch addresses the problem by comparing all flags except VM_LOCKED when deciding if pagetables should be shared or not for hugetlbfs-backed mapping.

The reservation behaviour differs depending on whether the mapping was mapped MAP_SHARED or MAP_PRIVATE. For MAP_SHARED mappings, hugepages are reserved when mmap() is first called and are tracked based on information associated with the inode. Other processes mapping MAP_SHARED use the same reservation. MAP_PRIVATE track the reservations based on the VMA created as part of the mmap() operation. Each process mapping MAP_PRIVATE must make its own reservation. hugetlbfs currently checks if a VMA is MAP_SHARED with the VM_SHARED flag and not VM_MAYSHARE. For file-backed mappings, such as hugetlbfs, VM_SHARED is set only if the mapping is MAP_SHARED and the file was opened read-write. If a shared memory mapping was mapped shared-read-write for populating of data and mapped shared-read-only by other processes, then hugetlbfs would account for the mapping as if it was MAP_PRIVATE. This causes processes to fail to map the file MAP_SHARED even though it should succeed as the reservation is there. This patch alters mm/hugetlb.c and replaces VM_SHARED with VM_MAYSHARE when the intent of the code was to check whether the VMA was mapped MAP_SHARED or MAP_PRIVATE.

So disregard a _PSS with a frequency so large that it can't be represented by cpufreq. https://bugzilla.redhat.com/show_bug.cgi?id=500311 Signed-off-by: Len Brown --- drivers/acpi/processor_perflib.c | 12 +++++++++--- 1 file changed, 9 insertions(+), 3 deletions(-) diff --git a/drivers/acpi/processor_perflib.c b/drivers/acpi/processor_perflib.c index cafb41000f6..60e543d3234 100644 --- a/drivers/acpi/processor_perflib.c +++ b/drivers/acpi/processor_perflib.c @@ -309,9 +309,15 @@ static int acpi_processor_get_performance_states(struct acpi_processor *pr) (u32) px->bus_master_latency, (u32) px->control, (u32) px->status)); - if (!px->core_frequency) { - printk(KERN_ERR PREFIX - "Invalid _PSS data: freq is zero\n"); + /* + * Check that ACPI's u64 MHz will be valid as u32 KHz in cpufreq + */ + if (!px->core_frequency || + ((u32)(px->core_frequency * 1000) != + (px->core_frequency * 1000))) { + printk(KERN_ERR FW_BUG PREFIX + "Invalid BIOS _PSS frequency: 0x%llx MHz\n", + px->core_frequency); result = -EFAULT; kfree(pr->performance->states); goto end; -- cgit v1.2.3 From 34ac272b3aaef11a91e19a72f3ac5772a96ffbc5 Mon Sep 17 00:00:00 2001 From: Zhang Rui Date: Tue, 26 May 2009 23:35:34 -0400 Subject: ACPI: video: DMI workaround broken eMachines E510 BIOS enabling display brightness http://bugzilla.kernel.org/show_bug.cgi?id=13376 Signed-off-by: Zhang Rui Signed-off-by: Len Brown --- drivers/acpi/video.c | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/drivers/acpi/video.c b/drivers/acpi/video.c index 810cca90ca7..ee45e760422 100644 --- a/drivers/acpi/video.c +++ b/drivers/acpi/video.c @@ -570,6 +570,14 @@ static struct dmi_system_id video_dmi_table[] __initdata = { DMI_MATCH(DMI_PRODUCT_NAME, "Aspire 5710Z"), }, }, + { + .callback = video_set_bqc_offset, + .ident = "eMachines E510", + .matches = { + DMI_MATCH(DMI_BOARD_VENDOR, "EMACHINES"), + DMI_MATCH(DMI_PRODUCT_NAME, "eMachines E510"), + }, + }, {} }; -- cgit v1.2.3 From 93bcece20ef87c29548ec7e66532f1018572cea0 Mon Sep 17 00:00:00 2001 From: Zhang Rui Date: Tue, 19 May 2009 15:08:41 -0400 Subject: ACPI: video: DMI workaround broken Acer 5315 BIOS enabling display brightness http://bugzilla.kernel.org/show_bug.cgi?id=13121 Signed-off-by: Zhang Rui Signed-off-by: Len Brown --- drivers/acpi/video.c | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/drivers/acpi/video.c b/drivers/acpi/video.c index ee45e760422..6d897bbd3bd 100644 --- a/drivers/acpi/video.c +++ b/drivers/acpi/video.c @@ -578,6 +578,14 @@ static struct dmi_system_id video_dmi_table[] __initdata = { DMI_MATCH(DMI_PRODUCT_NAME, "eMachines E510"), }, }, + { + .callback = video_set_bqc_offset, + .ident = "Acer Aspire 5315", + .matches = { + DMI_MATCH(DMI_BOARD_VENDOR, "Acer"), + DMI_MATCH(DMI_PRODUCT_NAME, "Aspire 5315"), + }, + }, {} }; -- cgit v1.2.3 From 1fc8d33acafe68bdcc21b327d22ef3820b819727 Mon Sep 17 00:00:00 2001 From: Jaswinder Singh Rajput Date: Wed, 20 May 2009 11:56:08 +0530 Subject: drm/i915: acpi/video.c fix section mismatch warning Currently acpi_video_exit() is exported as well as using __exit which causes: WARNING: drivers/acpi/video.o(__ksymtab+0x0): Section mismatch in reference from the variable __ksymtab_acpi_video_exit to the function .exit.text:acpi_video_exit() The symbol acpi_video_exit is exported and annotated __exit Fix this by removing the __exit annotation of acpi_video_exit or drop the export.

That resulted in xfs_fsr deadlocking itself on platforms, which don't handle double unlock of rw_semaphore nicely. It caused the count go negative, which represents the write holder, without really having one. ia64 is one of the platforms where deadlock was easily reproduced and the fix was tested.

The phy power state persists across reboots; Windows, some BIOSes, and older versions of Linux don't bother to power up the phy again, forcing users to remove all power to get the interface working (see http://bugzilla.kernel.org/show_bug.cgi?id=13072). Leaving the phy powered on is the safest default behavior. Users accustomed to seeing the link state reflect the interface state and/or wanting to minimize power consumption can set phy_power_down=1 if compatibility with other OSes is not an issue.

E1000 by default does two things: 1) Spans rx descriptors for packets that don't fit into 1 skb on recieve 2) Strips the crc from a frame by subtracting 4 bytes from the length prior to doing an skb_put Since the e1000 driver isn't written to support receiving packets that span multiple rx buffers, it checks the End of Packet bit of every frame, and discards it if its not set. This places us in a situation where, if we have a spanning packet, the first part is discarded, but the second part is not (since it is the end of packet, and it passes the EOP bit test). If the second part of the frame is small (4 bytes or less), we subtract 4 from it to remove its crc, underflow the length, and wind up in skb_over_panic, when we try to skb_put a huge number of bytes into the skb. This amounts to a remote DOS attack through careful selection of frame size in relation to interface MTU. The fix for this is already in the e1000e driver, as well as the e1000 sourceforge driver, but no one ever pushed it to e1000.

When we execute 'tc filter add', tcf_proto is allocated, initialized by classifier's init(), and chained. After it's chained, tc_ctl_tfilter() calls classifier's change(). When classifier's change() fails, tc_ctl_tfilter() does not free and keeps tcf_proto. In addition, cls_cgroup is initialized in change() not in init(). It accesses unconfigured struct tcf_proto which is chained before change(), then hits Oops.

Add drm_helper_connector_dpms. Making the drm_crtc.c code recognize the DPMS property and invoke the connector->dpms function doesn't remove any capability from the driver while reducing code duplication. That just highlighted the problem with the existing DPMS functions which could turn off the connector, but failed to turn off any relevant crtcs. The new drm_helper_connector_dpms function manages all of that, using the drm_helper-specific crtc and encoder dpms functions, automatically computing the appropriate DPMS level for each object in the system. This fixes the current troubles in the i915 driver which left PLLs, pipes and planes running while in DPMS_OFF mode or even while they were unused.

Stracing dd reveals that it first does an mmap2, which makes 1GB worth of zero page mappings. Then it performs a read on those pages from /dev/zero, and finally it performs a write. The machine died during the reads. Looking at the code, it was noticed that /dev/zero's read operation had been changed by 557ed1fa2620dc119adb86b34c614e152a629a80 ("remove ZERO_PAGE") from giving zero page mappings to actually zeroing the page. The zeroing of the pages causes physical pages to be allocated to the process. But, when the process exhausts all the memory that it can, the kernel cannot kill it, as it is still in the kernel mode allocating more memory. Consequently, the kernel eventually crashes. To fix this, I propose that when a fatal signal is pending during /dev/zero read operation, we simply return and let the user process die.
