commit 8a2e70c4 upstream. The refcount record calculation in ocfs2_calc_refcount_meta_credits is too optimistic that we can always allocate contiguous clusters and handle an already existed refcount rec as a whole. Actually because of file system fragmentation, we may have the chance to split a refcount record into 3 parts during the transaction. So consider the worst case in record calculation. Signed-off-by:

commit 7beaf243 upstream. This patch fixes two problems in dlm_run_purgelist 1. If a lockres is found to be in use, dlm_run_purgelist keeps trying to purge the same lockres instead of trying the next lockres. 2. When a lockres is found unused, dlm_run_purgelist releases lockres spinlock before setting DLM_LOCK_RES_DROPPING_REF and calls dlm_purge_lockres. spinlock is reacquired but in this window lockres can get reused. This leads to BUG. This patch modifies dlm_run_purgelist to skip lockres if it's in use and purge next lockres. It also sets DLM_LOCK_RES_DROPPING_REF before releasing the lockres spinlock protecting it from getting reused. Signed-off-by:

commit 6d98c3cc upstream. When we have to take both dlm->master_lock and lockres->spinlock, take them in order lockres->spinlock and then dlm->master_lock. The patch fixes a violation of the rule. We can simply move taking dlm->master_lock to where we have dropped res->spinlock since when we access res->state and free mle memory we don't need master_lock's protection. Signed-off-by:

commit 53bacfbb upstream. I discovered tonight that ALSA no longer sets up a stream for the second ADC provided by the Realtek ALC260 HDA codec. At some point alc_build_pcms() started using stream_analog_alt_capture when constructing the second ADC stream, but patch_alc260() was never updated accordingly. I have no idea when this regression occurred. The trivial patch to patch_alc260() given below fixes the problem as far as I can tell. The patch is against 2.6.35. Signed-off-by:

commit 56385a12 upstream. With some hardware combinations, the PCM interrupts are acknowledged before the period boundary from the emu10k1 chip. The midlevel PCM code gets confused and the playback stream is interrupted. It seems that the interrupt processing shift by 2 samples is enough to fix this issue. This default value does not harm other, non-affected hardware. More information: Kernel bugzilla bug#16300 [A copmile warning fixed by tiwai] Signed-off-by:

commit 0a7992c9 upstream. The ACPI_PREEMPTION_POINT() logic was introduced in commit 8bd108d1 (ACPICA: add preemption point after each opcode parse). The follow up commits abe1dfab, 138d1569, c084ca70 tried to fix the preemption logic back and forth, but nobody noticed that the usage of in_atomic_preempt_off() in that context is wrong. The check which guards the call of cond_resched() is: if (!in_atomic_preempt_off() && !irqs_disabled()) in_atomic_preempt_off() is not intended for general use as the comment above the macro definition clearly says: * Check whether we were atomic before we did preempt_disable(): * (used by the scheduler, *after* releasing the kernel lock) On a CONFIG_PREEMPT=n kernel the usage of in_atomic_preempt_off() works by accident, but with CONFIG_PREEMPT=y it's just broken. The whole purpose of the ACPI_PREEMPTION_POINT() is to reduce the latency on a CONFIG_PREEMPT=n kernel, so make ACPI_PREEMPTION_POINT() depend on CONFIG_PREEMPT=n and remove the in_atomic_preempt_off() check.

commit d7824370 upstream. This commit makes the stack guard page somewhat less visible to user space. It does this by: - not showing the guard page in /proc/<pid>/maps It looks like lvm-tools will actually read /proc/self/maps to figure out where all its mappings are, and effectively do a specialized "mlockall()" in user space. By not showing the guard page as part of the mapping (by just adding PAGE_SIZE to the start for grows-up pages), lvm-tools ends up not being aware of it. - by also teaching the _real_ mlock() functionality not to try to lock the guard page. That would just expand the mapping down to create a new guard page, so there really is no point in trying to lock it in place. It would perhaps be nice to show the guard page specially in /proc/<pid>/maps (or at least mark grow-down segments some way), but let's not open ourselves up to more breakage by user space from programs that depends on the exact deails of the 'maps' file. Special thanks to Henrique de Moraes Holschuh for diving into lvm-tools source code to see what was going on with the whole new warning.

commit 11ac5524 upstream. We do in fact need to unmap the page table _before_ doing the whole stack guard page logic, because if it is needed (mainly 32-bit x86 with PAE and CONFIG_HIGHPTE, but other architectures may use it too) then it will do a kmap_atomic/kunmap_atomic. And those kmaps will create an atomic region that we cannot do allocations in. However, the whole stack expand code will need to do anon_vma_prepare() and vma_lock_anon_vma() and they cannot do that in an atomic region. Now, a better model might actually be to do the anon_vma_prepare() when _creating_ a VM_GROWSDOWN segment, and not have to worry about any of this at page fault time. But in the meantime, this is the straightforward fix for the issue. See https://bugzilla.kernel.org/show_bug.cgi?id=16588 for details. Reported-by:

commit 96054569 upstream. It's wrong for several reasons, but the most direct one is that the fault may be for the stack accesses to set up a previous SIGBUS. When we have a kernel exception, the kernel exception handler does all the fixups, not some user-level signal handler. Even apart from the nested SIGBUS issue, it's also wrong to give out kernel fault addresses in the signal handler info block, or to send a SIGBUS when a system call already returns EFAULT.

commit 320b2b8d upstream. This is a rather minimally invasive patch to solve the problem of the user stack growing into a memory mapped area below it. Whenever we fill the first page of the stack segment, expand the segment down by one page. Now, admittedly some odd application might _want_ the stack to grow down into the preceding memory mapping, and so we may at some point need to make this a process tunable (some people might also want to have more than a single page of guarding), but let's try the minimal approach first. Tested with trivial application that maps a single page just below the stack, and then starts recursing. Without this, we will get a SIGSEGV _after_ the stack has smashed the mapping. With this patch, we'll get a nice SIGBUS just as the stack touches the page just above the mapping. Requested-by:

commit 437f88cc upstream. Commit 6b0310fb caused a regression resulting in deadlocks when freezing a filesystem which had active IO; the vfs_check_frozen level (SB_FREEZE_WRITE) did not let the freeze-related IO syncing through. Duh. Changing the test to FREEZE_TRANS should let the normal freeze syncing get through the fs, but still block any transactions from starting once the fs is completely frozen. I tested this by running fsstress in the background while periodically snapshotting the fs and running fsck on the result. I ran into occasional deadlocks, but different ones. I think this is a fine fix for the problem at hand, and the other deadlocky things will need more investigation. Reported-by:

commit 4877c737 upstream. In general the semantics of IPIs are that they are are expected to continue functioning after dpm_suspend_noirq(). Specifically I have seen a deadlock between the callfunc IPI and the stop machine used by xen's do_suspend() routine. If one CPU has already called dpm_suspend_noirq() then there is a window where it can be sent a callfunc IPI before all the other CPUs have entered stop_cpu(). If this happens then the first CPU ends up spinning in stop_cpu() waiting for the other to rendezvous in state STOPMACHINE_PREPARE while the other is spinning in csd_lock_wait(). Signed-off-by:

commit b3e67044 upstream. This patch fixes a race condition in two utility routines related to the removal/unlinking of urbs from an anchor. If two threads are concurrently accessing the same anchor, both could end up with the same urb - thinking they are the exclusive owner. Alan Stern pointed out a related issue in usb_unlink_anchored_urbs: "The URB isn't removed from the anchor until it completes (as a by-product of completion, in fact), which might not be for quite some time after the unlink call returns. In the meantime, the subroutine will keep trying to unlink it, over and over again." Cc: Oliver Neukum <oneukum@suse.de> Cc: Greg Kroah-Hartman <greg@kroah.com> Acked-by:

commit b6180ef7 upstream. This patch is to add a US Interface, Inc. "Navigator" USB device. Specifically, it's a HAM Radio USB sound modem that also incorporates three pairs of unique FTDI serial ports. The standard Linux FTDI serial driver will only recognize the first two serial ports of an unknown FDTI derived device and this patch adds in recognition to these specific new IDs. Signed-off-by:

commit 0372a754 upstream. This patch adds the product IDs of Huawei's K3765 and K4505 mobile broadband usb modems to option.c. It also adds a quirk to the option probe function so that binding to the device's network interface(class 0xff) is avoided. This is necessary to allow another driver to bind to that, and to avoid programs like wvdial opening a nonfunctioning tty during modem discovery. Signed-off-by:
