From 6b8036a877fe7a85d4474ddb89993339303959e1 Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Sat, 28 Feb 2009 21:30:38 -0700 Subject: powerpc/4xx: Enable SERIAL_OF support by default for Virtex platforms Virtex FPGA designs have two serial port logic cores to choose from; the simple uartlite, and the full featured uart16550. Both cores are in common use so the defconfig should support both of them. Currently only console on uartlite is supported in the defconfig. This patch adds console support for the 16550 core. The Virtex reference designs do not work without this patch.

Miller" Date: Wed, 4 Mar 2009 14:43:47 -0800 Subject: sparc64: Fix lost interrupts on sun4u. Based upon a report by Meelis Roos. Sparc64 SBUS and PCI controllers use a combination of IMAP and ICLR registers to manage device interrupts. The IMAP register contains the "valid" enable bit as well as CPU targetting information. Whereas the ICLR register is written with zero at the end of handling an interrupt to reset the state machine for that interrupt to IDLE so it can be sent again. For PCI slot and SBUS slot devices we can have multiple interrupts sharing the same IMAP register. There are individual ICLR registers but only one IMAP register for managing those. We represent each shared case with individual virtual IRQs so the generic IRQ layer thinks there is only one user of the IRQ instance. In such shared IMAP cases this is wrong, so if there are multiple active users then a free_irq() call will prematurely turn off the interrupt by clearing the Valid bit in the IMAP register even though there are other active users. Fix this by simply doing nothing in sun4u_disable_irq() and checking IRQF_DISABLED during IRQ dispatch. This situation doesn't exist in the hypervisor sun4v cases, so I left those alone.

The fcoe_xmit was getting called with bh disabled, thus causing "BUG: scheduling while atomic" when grabbing lport->lp_muex with bh disabled. 2. fc_linkup and fc_linkdown function calls lport_enter function with lport->lp_mutex held and these enter function in turn calls fcoe_xmit to send lport related FC frame, e.g. fc_linkup => fc_lport_enter_flogi to send flogi req. In this case grabbing the same lport->lp_mutex again in fc_puase from fcoe_xmit would cause deadlock. The lport->lp_mutex was used for setting FC_PAUSE in fcoe_xmit path but FC_PAUSE bit was not used anywhere beside just setting and clear this bit in lport->link_status, instead used a separate field qfull in fc_lport to eliminate need for lport->lp_mutex to track pending queue full condition and in turn avoid above described two locking issues. Also added check for lp->qfull in fc_fcp_lport_queue_ready to trigger SCSI_MLQUEUE_HOST_BUSY when lp->qfull is set to prevent more scsi-ml cmds while lp->qfull is set. This patch eliminated FC_LINK_UP and FC_PAUSE and instead used dedicated fields in fc_lport for this, this simplified all related conditional code. Also removed fc_pause and fc_unpause functions and instead used newly added lport->qfull directly in fcoe.

The rport error handling would only retry on resource allocation failures and exchange timeouts. I have a target that will occasionally reject PLOGI when we do a quick LOGO/PLOGI. When a critical ELS was rejected, libfc would fail silently leaving the rport in a dead state. The retry count and delay are managed by fc_rport_error_retry. If the retry count is exceeded fc_rport_error will be called. When retrying is not the correct course of action, fc_rport_error can be called directly.

Thus if fc_exch_alloc() is called when retrying the sequence, the mempool_alloc() will fail to allocate the exchange because the mempool of the exchange manager has already been released. This patch is to cancel any pending retry work of the local port before we start to destroy the interface. Also, when resetting the local port, we should also stop the scheduled pending retries.

If we destroy the interface, we'll go through each rport on the disc->rports list and set each rport's state to NONE. Then the lport will reset the EM. The EM reset will send a CLOSED event to the prli_resp() handler which will notice that the state != PRLI. In this case it frees the frame pointer, decrements the refcount and unlocks the rport. The problem is that there isn't a frame in this case. It's just a pointer with an embedded error code. The free causes an Oops. This patch moves the error checking to be before the state checking.

[sdp] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE,SUGGEST_OK [sdp] Sense Key : Aborted Command [current] [sdp] Add. Sense: Data phase error This was causing some test apps to exit due to write failure under heavy load. This was due to a race around adding and removing tx frame skb in fcoe_pending_queue, Chris Leech helped me to find that brief unlocking period when pulling skb from fcoe_pending_queue in various contexts (fcoe_watchdog and fcoe_xmit) and then adding skb back into fcoe_pending_queue up on a failed fcoe_start_io could change skb/tx frame order in fcoe_pending_queue. Thanks Chris. This patch allows only single context to pull skb from fcoe_pending_queue at any time to prevent above described ordering issue/race by use of fcoe_pending_queue_active flag. This patch simplified fcoe_watchdog with modified fcoe_check_wait_queue by use of FCOE_LOW_QUEUE_DEPTH instead previously used several conditionals to clear and set lp->qfull. I think FCOE_MAX_QUEUE_DEPTH with FCOE_LOW_QUEUE_DEPTH will work better in re/setting lp->qfull and these could be fine tuned for performance.

This resulted in out of order data frames within a single sequence, leading to IO timeout errors. This builds on the approach from Vasu Dev to only fix the queue management in fcoe_check_wait_queue, where my first patch added locking to the transmit path even when the pending queue was not in use. This patch continues to use fcoe_pending_queue.qlen instead of introducing a new length counter, but takes precautions to ensure it never drops to 0 before the final frame in the queue has successfully been passed to the netdev qdisc layer. It also includes some cleanup of fcoe_check_wait_queue and removes the fcoe_insert_wait_queue(_head) wrapper functions.

Most filesystems have 3 or 4 of these structs total, and the list is only changed when new raid levels are added or at unmount time. This commit adds rcu locking on the list head, and properly frees things at unmount time. It also clears the space_info->full flag whenever new space is added to the FS. The locking for the space info list goes like this: reads: protected by rcu_read_lock() writes: protected by the chunk_mutex At unmount time we don't need special locking because all the readers are gone.

The ext4_ext_search_right() function is confusing; it uses a "depth" variable which is 0 at the root and maximum at the leaves, but the on-disk metadata uses a "depth" (actually eh_depth) which is opposite: maximum at the root, and 0 at the leaves. The ext4_ext_check_header() function is given a depth and checks the header agaisnt that depth; it expects the on-disk semantics, but we are giving it the opposite in the while loop in this function. We should be giving it the on-disk notion of "depth" which we can get from (p_depth - depth) - and if you look, the last (more commonly hit) call to ext4_ext_check_header() does just this.

This is useful for debugging wakup problems, but unfortunately, this also became a source of problems of its own. The hook is called extremely early, with interrupts still off, and the code path involved with that code nowadays rely on things like taking mutexes, GFP_KERNEL allocations, etc... In addition, the driver now relies on the PCI core to restore the standard config space before calling resume which doesn't happen with this early code path. I'm keeping the code in but commented out along with a fixup call to pci_restore_state(). The reason is that I still want to make it easy to re-enable temporarily to track wake up problems, and it's possible that I can revive it at some stage if we make sleeping things save to call in early resume using a system state. In the meantime, this should fix several reported regressions.

There have been multiple reports on different kernel versions pointing to this common issue: http://bugzilla.kernel.org/show_bug.cgi?id=12557 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/269954 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=508866.html This issue can be reproducible consistently by doing this on a NFS mounted home (KDE): 1. Open 2 xterm sessions 2. From one of the xterm session, do "ssh -X " 3. "stat ~/.Xauthority" on the remote SSH session 4. Close the two xterm sessions 5. On the server do a "stat ~/.Xauthority" 6. Now on the client, try to open xterm This will fail. Even if the filehandle had become stale, the NFS client should invalidate the cache/inode and should repeat LOOKUP. Looking at the packet capture when the failure occurs shows that there were two subsequent ACCESS() calls with the same filehandle and both fails with -ESTALE error. I have tested the fix below. Now the client issue a LOOKUP after the ACCESS() call fails with -ESTALE. If all this makes sense to you, can you consider this for inclusion? Thanks, If the server returns an -ESTALE error due to stale filehandle in response to an ACCESS() call, we need to invalidate the cache and inode so that LOOKUP() can be retried. Without this change, the nfs client retries ACCESS() with the same filehandle, fails again and could lead to temporary failure of applications running on nfs mounted home.

This check triggered if zlib_inflate asked to be called again (Z_OK) with avail_out == 0 and no more output buffers available. This check proves to be rather dumb, as it incorrectly catches the case where zlib has generated all the output, but there are still input bytes to be processed. This patch does a number of things. It removes the original check and replaces it with code to not move to the next output buffer if there are no more output buffers available, relying on zlib to error if it wants an extra output buffer in the case of data corruption. It also replaces the Z_NO_FLUSH flag with the more correct Z_SYNC_FLUSH flag, and makes the error messages more understandable to non-technical users.

The workaround had been added for 82575 (igb) previously, but did not use the ASPM api. This quirk uses the ASPM api to prevent the ASPM subsystem from re-enabling the L0s state. Instead of adding the fix in igb to the ixgbe driver as well it was decided to move it into a pci quirk. It is necessary to move the fix out of the driver and into a pci quirk in order to prevent the issue from occuring prior to driver load to handle the possibility of the device being passed to a VM via direct assignment.

PTRACE_SYSEMU/SUSEMU_SINGLESTEP is not captured in arch_ptrace's switch, therefore it is erroneously passed back to ptrace_request (in kernel/ptrace).

As a result, we end up with no backlight device at all. We should instead disable it if there is an ACPI device, as the other laptop drivers do. This regression was introduced in febf2d9 ("Acer-WMI: fingers off backlight if video.ko is serving this functionality"). Each laptop driver with backlight support got a similar change around febf2d9. The changes to the other drivers look correct; see e.g. a598c82f for a similar but correct change. The regression is also in 2.6.28.

There is a script included to reproduce the problem. During testing, I encountered a number of strange things with ext3, so I tried ext2 to attempt to reduce complexity of the problem. I found that fsstress would quickly hang in wait_on_inode, waiting for I_LOCK to be cleared, even though instrumentation showed that unlock_new_inode had already been called for that inode. This points to memory scribble, or synchronisation problme. i_state of I_NEW inodes is not protected by inode_lock because other processes are not supposed to touch them until I_LOCK (and I_NEW) is cleared. Adding WARN_ON(inode->i_state & I_NEW) to sites where we modify i_state revealed that generic_sync_sb_inodes is picking up new inodes from the inode lists and passing them to __writeback_single_inode without waiting for I_NEW. Subsequently modifying i_state causes corruption. In my case it would look like this: CPU0 CPU1 unlock_new_inode() __sync_single_inode() reg <- inode->i_state reg -> reg & ~(I_LOCK|I_NEW) reg <- inode->i_state reg -> inode->i_state reg -> reg | I_SYNC reg -> inode->i_state Non-atomic RMW on CPU1 overwrites CPU0 store and sets I_LOCK|I_NEW again. Fix for this is rather than wait for I_NEW inodes, just skip over them: inodes concurrently being created are not subject to data integrity operations, and should not significantly contribute to dirty memory either. After this change, I'm unable to reproduce any of the added warnings or hangs after ~1hour of running. Previously, the new warnings would start immediately and hang would happen in under 5 minutes. I'm also testing on ext3 now, and so far no problems there either. I don't know whether this fixes the problem reported above, but it fixes a real problem for me.

The nes driver unfortunately allows STag zero to be used even with QPs created by unprivileged userspace consumers, which means that any process with direct verbs access to the nes device can read and write any memory accessible to the underlying PCI device (usually any memory in the system). Such access is usually given for cluster software such as MPI to use, so this is a local privilege escalation bug on most systems running this driver. The driver was using STag zero to receive the last streaming mode data; to allow STag zero to be disabled for unprivileged QPs, the driver now registers a special MR for this data.

Now we use ocfs2_xattr_bucket to abstract xattr bucket and xs->base is initialized to the start of the bu_bhs[0]. So xs->base + offset will overflow when the value root is stored outside the first block. Then why we can survive the xattr test by now? It is because we always read the bucket contiguously now and kernel mm allocate continguous memory for us. We are lucky, but we should fix it. So just get the right value root as other callers do.

Although GregKH will revert this patch, there's no reason we should be using the iterators directly, we can just move to the standard device_for_each_child() API.

The board doesn't expose the first port but somehow SStatus reports link online while failing SRST protocol leading to repeated probe failures and thus long boot delay. Because the BIOS doesn't carry any identifying DMI information, the port can't be blacklisted safely. Fortunately, the controller does have subsystem vendor and ID set. It's unclear whether the subsystem IDs are used only for the board but it can be safely worked around by disabling SIDPR access and just using SRST works around the problem. Even when the workaround is triggered on an unaffected board the only side effect will be missing SCR access.

17 00:00:00 2001 From: Lennert Buytenhek Date: Fri, 13 Mar 2009 15:48:02 -0700 Subject: mv643xx_eth: fix unicast address filter corruption on mtu change When mv643xx_eth_open() is called to up an interface, port_start() will first re-program the unicast address filter, and then re-initialise the PORT_CONFIG register, but that will disable unicast promiscuous mode if it was enabled by the unicast address filter setup. This isn't a problem on ifconfig up, as ->set_rx_mode() will be called shortly afterwards which will program the filters again, but it does trigger when changing the MTU, which calls mv643xx_eth_stop() and then mv643xx_eth_open() by hand to repopulate the receive rings with skbuffs of the new size. Swap the initialisation of the PORT_START register and the call to the unicast filter setup function to fix this. Signed-off-by: Lennert Buytenhek Signed-off-by: David S.

The problem is that the pages are not marked dirty. Anything that creates data in an MMU-based ramfs will cause the pages holding that data will cause the set_page_dirty() aop to be called. For the NOMMU-based mmap, set_page_dirty() may be called by write(), but it won't be called by page-writing faults on writable mmaps, and it isn't called by ramfs_nommu_expand_for_mapping() when a file is being truncated from nothing to allocate a contiguous run. The solution is to mark the pages dirty at the point of allocation by the truncation code.

The per-file FEK is encrypted with one or more FEKEKs and stored in the header of the encrypted file. I noticed that the FEK is also being encrypted by the FNEK. This is a problem if a user wants to use a different FNEK than their FEKEK, as their file contents will still be accessible with the FNEK. This is a minimalistic patch which prevents the FNEKs signatures from being copied to the inode signatures list. Ultimately, it keeps the FEK from being encrypted with a FNEK.

With the following patch we: - properly randomize choice value for normal choice blocks - properly randomize for multi choice blocks - added several comments to explain what is going on The root cause of the bug was that SYMBOL_VALID was set on the symbol representing the choice block so clearing this did the trick initially. But testign revealed a few more issues that is now fixed.

My Nehalem testbox does randconfig much faster than 1 second and i have a few scripts that do 'randconfig until condition X' loops. Those scripts currently waste a lot of CPU time due to randconfig changing its seed only once per second currently. Change the seed to be micrseconds based. (I checked the statistical spread of the seed - the now.tv_sec*now.tv_usec multiplication there further improves it.)

Only crypto_async_request->data is guaranteed to be same as the one passed in. The current kcryptd_async_done uses the passed-in crypto_async_request directly which may cause the AES-NI-based AES algorithm implementation to panic. This patch fixes this bug by only using crypto_async_request->data, which points to dm_crypt_request, the crypto_async_request passed in. The original data (convert_context) is gotten from dm_crypt_request.

to merge the non-MMU and MMU versions of siginfo.h. Without a single file "make headers_install" is broken for m68k (since each of the sub-varients of siginfo.h are not installed).

ext4_lock_group(sb, grp); list_del(&pa->pa_group_list); ext4_unlock_group(sb, grp); so it's critical that we get the right group number back for this prealloc context, to lock the right group (the one associated with this pa) and prevent concurrent list manipulation. however, ext4_mb_put_pa() passes in (pa->pa_pstart - 1) with a comment, "-1 is to protect from crossing allocation group". This makes sense for the group_pa, where pa_pstart is advanced by the length which has been used (in ext4_mb_release_context()), and when the entire length has been used, pa_pstart has been advanced to the first block of the next group.

That will happens at the next CLK pulse (1.193182 MHz), so the easiest way to do that is to just wait at least one microsecond after programming the new PIT counter value. We do that by just reading the counter value back once - which will take about 2us on PC hardware.

The fast TSC PIT calibration sometimes failed this test - it was assuming that the PIT reads always took about one microsecond each (2us for the two reads to get a 16-bit timer), and that calibrating TSC to the PIT over 15ms should thus be sufficient to get much closer than 500ppm (max 2us error on both sides giving 4us over 15ms: a 270 ppm error value). However, that assumption does not always hold: apparently some hardware is either very much slower at reading the PIT registers, or there was other noise causing at least one machine to get 700+ ppm errors. So instead of using a fixed 15ms timing loop, this changes the fast PIT calibration to read the TSC delta over the individual PIT timer reads, and use the result to calculate the error bars on the PIT read timing properly. We then successfully calibrate the TSC only if the maximum error bars fall below 500ppm. In the process, we also relax the timing to allow up to 25ms for the calibration, although it can happen much faster depending on hardware.

In the process, that caused the operations to be done on the full 64 bits, even though the offset is never that big. That's all fine and dandy per se, but for some unfathomable reason gcc generates absolutely horrid code when using 64-bit values in switch() statements. To the point of actually calling out to gcc helper functions like __cmpdi2 rather than just doing the trivial comparisons directly the way gcc does for normal compares. At which point we get link failures, because we really don't want to support that kind of crazy code. Fix this by just casting the f_pos value to "unsigned long", which is plenty big enough for /proc, and avoids the gcc code generation issue.

But it is too eager to free the entries on this list: destroy_async() gets called whenever an interface is unbound or a device is removed, and it deallocates the outstanding struct async entries for all URBs on that interface or device. This is wrong; the user program should be able to reap an URB any time after it has completed, regardless of whether or not the interface is still bound or the device is still present. This patch (as1222) moves the code for deallocating the completed list entries from destroy_async() to usbdev_release(). The outstanding entries won't be freed until the user program has closed the device file, thereby eliminating any possibility that the remaining URBs might still be reaped. This fixes a bug in which a program can hang in the USBDEVFS_REAPURB ioctl when the device is unplugged.

The culprit is *usb being set to NULL when usb_put_urb() is called after URB is given back. Due to other fixes there is no need for ehci-hcd to deal with usb_get_urb() nor usb_put_urb() anymore, so patch removes their usages in ehci-hcd.

The condition for whether unlinked QHs can become IDLE should not be that the controller is halted, but rather that the controller isn't running. In other words when the root hub is suspended, the hardware doesn't own any QHs. This fixes a problem that can show up during hibernation: If a QH is only partially unlinked when the root hub is frozen, then when the root hub is thawed the QH won't be in the IDLE state. As a result it can't be used properly for new URB submissions.

But this is not always true, e.g. the generic page table walker does not guarantee this. Change TASK_SIZE/TASK_SIZE_OF to reflect the current size of the address space.

The MSI-X handler was chosen before the call to pci_enable_msix(). If MSI-X was not available, the wrong MSI-X handler would be used in INTA mode. This would cause a screaming interrupt problem because INTA would not be cleared by the MSI-X handler. Fixed by assigning MSI-X handler after pci_enable_msix() returns successfully. Also update version to 1.9.3. Thomas Chenault helped us find this problem. Signed-off-by: Michael Chan Signed-off-by: David S.

This allows a seamless experience with e.g., qemu/kvm where NetworkManager just configures and sets up everything automagically. If/when a generally agreed-upon way to control carrier on/off in the emulator/hypervisor level emerges, it will be trivial to extend the driver to support that too, but for now even this 2-liner makes user experience that much better.

This patch clears the last known values every time the interface is brought up, instead of only when the module is loaded. Without this patch the adjust_link function never updates the hardware after an ifconfig down; ifconfig up. On a full duplex link this causes the tx error counter to increment, even though packets are correctly transmitted, as the default MAC_CR register setting is for half duplex. The tx errors are "no carrier" errors, which should be ignored in full-duplex mode. When MAC_CR is set to "full duplex" mode they are correctly ignored by the hardware. Note that even with this patch the tx error counter can increment if packets are transmitted between "ifconfig up" and the first phy poll interval. An improved solution would use the phy interrupt with phylib, but I haven't managed to make this work 100% robustly yet. Signed-off-by: Steve Glendinning Signed-off-by: David S.

Myself, like Eric, wasn't able to reproduce an fput() call from IRQ context, but Jeff said he was able to, with the attached test program. Independently from this, the bug is conceptually there, so we might be better off fixing it. This patch adds an optimization similar to the one we already do on ->ki_filp, on ->ki_eventfd. Playing with ->f_count directly is not pretty in general, but the alternative here would be to add a brand new delayed fput() infrastructure, that I'm not sure is worth it.

Because of that, an extra put_iocontext was done, and when the process exited, it hit a BUG_ON in the put_iocontext macro called from exit_aio (since we expect a users count of 1 and instead get 0). The problem was introduced by "aio: make the lookup_ioctx() lockless" (commit abf137dd7712132ee56d5b3143c2ff61a72a5faa). Thanks to Zach for pointing out that hlist_for_each_entry_rcu will not return with a NULL tpos at the end of the loop, even if the entry was not found.

However, the size of an eCryptfs header is either PAGE_CACHE_SIZE or ECRYPTFS_MINIMUM_HEADER_EXTENT_SIZE (8192), whichever is larger, and is stored in the file's private_data->crypt_stat->num_header_bytes_at_front field. ecryptfs_write_metadata_to_contents() was using num_header_bytes_at_front to decide how many bytes should be written to the lower filesystem for the file header. Unfortunately, at least 8K was being written from the page, despite the chance of the single, zeroed page being smaller than 8K. This resulted in random areas of kernel memory being written between the 0x1000 and 0x1FFF bytes offsets in the eCryptfs file headers if PAGE_SIZE was 4K. This patch allocates a variable number of pages, calculated with num_header_bytes_at_front, and passes the number of allocated pages along to ecryptfs_write_metadata_to_contents().

It calls request_irq() without setting IRQF_DISABLED ... which is correct for handlers that support IRQ sharing, since that behavior is not guaranteed for shared IRQs. However, its IRQ handler then wrongly assumes that IRQs are blocked. So the fix just uses the right spinlock primitives in the IRQ handler. NOTE: this is a classic example of the type of bug which lockdep currently masks by forcibly setting IRQF_DISABLED on IRQ handlers that did not request that flag.

Also, since we fully construct phy_bus_id in the _probe() routine, we no longer need ->phy_address and ->mdio_bus fields in ucc_geth_info structure. I wish the patch would be a bit shorter, but it seems like the only way to fix the issue in a sane way. Luckily, the patch has been tested with real PHYs and fixed-link, so no further regressions expected.

The problem is this: - task A is ptracing task B - task B stops on a trace event - task A is woken up and preempts task B - task A calls ptrace on task B, which does ptrace_check_attach() - this calls wait_task_inactive(), which sees that task B is still on the runq - task A goes to sleep for a jiffy - ... Since UML does lots of the above sequences, those jiffies quickly add up to make it slow as hell. This patch solves this by not rescheduling in read_unlock() after ptrace_stop() has woken up the tracer. Thanks to Oleg Nesterov and Ingo Molnar for the feedback.

Certain architectures (powerpc, in this case) may generate unexpected relocation formats in response to this, preventing modules from loading. While the new relocation types should probably be handled, revert to the previous behaviour with regards to generation of .eh_frame sections.

In OMAP sDMA, contrast to the SDMA.DMA4_CSRi registers, the SDMA.DMA4_IRQSTATUS_Lj registers are updated regardless of the corresponding bits in the SDMA.DMA4_IRQENABLE_Lj registers. Since there are four sDMA interrupt lines and if more than one line is actively used by two concurrently running sDMA softwares modules,then the spurious interrupt can be observed on the other lines. Fix in this patch will only dispatch the relevant and enabled interrupts on a particular line thus perevting spurious IRQ.
