2008-07-12ov7670: clean up ov7670_read semanticsAndres Salomon
Cortland Setlow pointed out a bug in ov7670.c where the result from ov7670_read() was just being checked for !0, rather than <0. This made me realize that ov7670_read's semantics were rather confusing; it both fills in 'value' with the result, and returns it. This is goes against general kernel convention; so rather than fixing callers, let's fix the function. This makes ov7670_read return <0 in the case of an error, and 0 upon success. Thus, code like: res = ov7670_read(...); if (!res) goto error; ..will work properly.

I had 8250.nr_uarts=16 in the boot line of a test kernel and I had a weird mysterious crash in sysfs. After taking an in-depth look I realized that CONFIG_SERIAL_8250_NR_UARTS was set to 4 and I was walking off the end of the serial8250_ports array. Ouch!!! Don't let this happen to someone else.

2008-07-12fbdev: bugfix for multiprocess defioJaya Kumar
This patch is a bugfix for how defio handles multiple processes manipulating the same framebuffer. Thanks to Bernard Blackham for identifying this bug. It occurs when two applications mmap the same framebuffer and concurrently write to the same page. Normally, this doesn't occur since only a single process mmaps the framebuffer. The symptom of the bug is that the mapping applications will hang. The cause is that defio incorrectly tries to add the same page twice to the pagelist. The solution I have is to walk the pagelist and check for a duplicate before adding. Since I needed to walk the pagelist, I now also keep the pagelist in sorted order.

2008-07-11Fix reference counting race on log buffersDave Chinner
When we release the iclog, we do an atomic_dec_and_lock to determine if we are the last reference and need to trigger update of log headers and writeout. However, in xlog_state_get_iclog_space() we also need to check if we have the last reference count there. If we do, we release the log buffer, otherwise we decrement the reference count. But the compare and decrement in xlog_state_get_iclog_space() is not atomic, so both places can see a reference count of 2 and neither will release the iclog. That leads to a filesystem hang. Close the race by replacing the atomic_read() and atomic_dec() pair with atomic_add_unless() to ensure that they are executed atomically.

2008-07-11libata-acpi: filter out DIPM enableTejun Heo
Some BIOSen enable DIPM via _GTF which causes command timeouts under certain configuration. This didn't occur on 2.6.25 because 2.6.25 defaulted to SRST, so _GTF wasn't executed during boot probe, so ahci host reset disabled DIPM and as _GTF wasn't executed after SRST, DIPM wasn't enabled. On 2.6.26, hardreset is used during probe and after probe _GTF is executed enabling DIPM and thus the failures. This patch could theoretically disable DIPM on machines which used to have it enabled on 2.6.25 but AFAIK ahci is currently the only driver which uses SATA ACPI hierarchy (_SDD) and as the host reset would have always disabled DIPM, this shouldn't happen.

2008-07-10rtc: fix reported IRQ rate for when HPET is enabledPaul Gortmaker
The IRQ rate reported back by the RTC is incorrect when HPET is enabled. Newer hardware that has HPET to emulate the legacy RTC device gets this value wrong since after it sets the rate, it returns before setting the variable used to report the IRQ rate back to users of the device -- so the set rate and the reported rate get out of sync.

2008-07-10tun: Persistent devices can get stuck in xoff stateMax Krasnyansky
The scenario goes like this. App stops reading from tun/tap. TX queue gets full and driver does netif_stop_queue(). App closes fd and TX queue gets flushed as part of the cleanup. Next time the app opens tun/tap and starts reading from it but the xoff state is not cleared. We're stuck. Normally xoff state is cleared when netdev is brought up. But in the case of persistent devices this happens only during initial setup. The fix is trivial. If device is already up when an app opens it we clear xoff state and that gets things moving again.

Where did "c" come from? Uh-oh... c = get_cpu_slab(s, smp_processor_id()); This looks like it has very much to do with CPU hotplug/unplug. Is there a race between SLUB/hotplug since the CPU slab is used after it has been freed?" Good analysis. Yeah, it's possible that a caller of kmem_cache_alloc() -> slab_alloc() can be migrated on another CPU right after local_irq_restore() and before memset(). The inital cpu can become offline in the mean time (or a migration is a consequence of the CPU going offline) so its 'kmem_cache_cpu' structure gets freed ( slab_cpuup_callback). At some point of time the caller continues on another CPU having an obsolete pointer...

2008-07-10exec: fix stack excutability without PT_GNU_STACKHugh Dickins
Kernel Bugzilla #11063 points out that on some architectures (e.g. x86_32) exec'ing an ELF without a PT_GNU_STACK program header should default to an executable stack; but this got broken by the unlimited argv feature because stack vma is now created before the right personality has been established: so breaking old binaries using nested function trampolines. Therefore re-evaluate VM_STACK_FLAGS in setup_arg_pages, where stack vm_flags used to be set, before the mprotect_fixup. Checking through our existing VM_flags, none would have changed since insert_vm_struct: so this seems safer than finding a way through the personality labyrinth.

2008-07-10Fix PREEMPT_RCU without HOTPLUG_CPUNick Piggin
PREEMPT_RCU without HOTPLUG_CPU is broken. The rcu_online_cpu is called to initially populate rcu_cpu_online_map with all online CPUs when the hotplug event handler is installed, and also to populate the map with CPUs as they come online. The former case is meant to happen with and without HOTPLUG_CPU, but without HOTPLUG_CPU, the rcu_offline_cpu function is no-oped -- while it still gets called, it does not set the rcu CPU map. With a blank RCU CPU map, grace periods get to tick by completely oblivious to active RCU read side critical sections. This results in free-before-grace bugs. Fix is obvious once the problem is known. (Also, change __devinit to __cpuinit so the function gets thrown away on !HOTPLUG_CPU kernels).

When a conntrack entry is destroyed in process context and destruction is interrupted by packet processing and the packet is an attempt to reopen a closed connection, TCP conntrack tries to kill the old entry itself and returns NF_REPEAT to pass the packet through the hook again. This may lead to an endless loop: TCP conntrack repeatedly finds the old entry, but can not kill it itself since destruction is already in progress, but destruction in process context can not complete since TCP conntrack is keeping the CPU busy. Drop the packet in TCP conntrack if we can't kill the connection ourselves to avoid this.
