commit 0b46b8a7 upstream. This is a bug fix for using physical arch timers when the arch_timer_use_virtual boolean is false. It restores the arch_counter_get_cntpct() function after removal in 0d651e4e "clocksource: arch_timer: use virtual counters" We need this on certain ARMv7 systems which are architected like this: * The firmware doesn't know and doesn't care about hypervisor mode and we don't want to add the complexity of hypervisor there. * The firmware isn't involved in SMP bringup or resume. * The ARCH timer come up with an uninitialized offset between the virtual and physical counters. Each core gets a different random offset. * The device boots in "Secure SVC" mode. * Nothing has touched the reset value of CNTHCTL.PL1PCEN or CNTHCTL.PL1PCTEN (both default to 1 at reset) One example of such as system is RK3288 where it is much simpler to use the physical counter since there's nobody managing the offset and each time a core goes down and comes back up it will get reinitialized to some other random value.

commit 1f563a6a upstream. Kernel side fence objects are used when unbinding resources and may thus be created as part of a memory reclaim operation. This might trigger recursive memory reclaims and result in the kernel running out of stack space. So a simple way out is to avoid accounting of these fence objects. In principle this is OK since while user-space can trigger the creation of such objects, it can't really hold on to them. However, their lifetime is quite long, so some form of accounting should perhaps be implemented in the future. Fixes kernel crashes when running, for example viewperf11 ensight-04 test 3 with low system memory settings. Signed-off-by:

commit d472fcc8 upstream. The problem here is that SNA pins batchbuffers to etch out a bit more performance. Iirc it started out as a w/a for i830M (which we've implemented in the kernel since a long time already). The problem is that the pin ioctl wasn't added in commit d23db88c Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Fri May 23 08:48:08 2014 +0200 drm/i915: Prevent negative relocation deltas from wrapping Fix this by simply disallowing pinning from userspace so that the kernel is in full control of batch placement again. Especially since distros are moving towards running X as non-root, so most users won't even be able to see any benefits. UMS support is dead now, but we need this minimal patch for backporting. Follow-up patch will remove the pin ioctl code completely.

commit 108cef3a upstream. It is critical that fetch_block() and handle_stripe_dirtying() are consistent in their analysis of what needs to be loaded. Otherwise raid5 can wait forever for a block that won't be loaded. Currently when writing to a RAID5 that is resyncing, to a location beyond the resync offset, handle_stripe_dirtying chooses a reconstruct-write cycle, but fetch_block() assumes a read-modify-write, and a lockup can happen. So treat that case just like RAID6, just as we do in handle_stripe_dirtying. RAID6 always does reconstruct-write. This bug was introduced when the behaviour of handle_stripe_dirtying was changed in 3.7, so the patch is suitable for any kernel since, though it will need careful merging for some versions.

commit a40687ff upstream. If a stripe in a raid6 array received a write to each data block while the array is degraded, and if any of these writes to a missing device are not page-aligned, then a live-lock happens. In this case the P and Q blocks need to be read so that the part of the missing block which is *not* being updated by the write can be constructed. Due to a logic error, these blocks are not loaded, so the update cannot proceed and the stripe is 'handled' repeatedly in an infinite loop. This bug is unlikely as most writes are page aligned. However as it can lead to a livelock it is suitable for -stable. It was introduced in 3.16. Fixed: 67f45548Signed-off-by:

commit 67f45548 upstream. If it is found that we need to pre-read some blocks before a write can succeed, we normally set STRIPE_DELAYED and don't actually perform the read until STRIPE_PREREAD_ACTIVE subsequently gets set. However for a degraded RAID6 we currently perform the reads as soon as we see that a write is pending. This significantly hurts throughput. So: - when handle_stripe_dirtying find a block that it wants on a device that is failed, set STRIPE_DELAY, instead of doing nothing, and - when fetch_block detects that a read might be required to satisfy a write, only perform the read if STRIPE_PREREAD_ACTIVE is set, and if we would actually need to read something to complete the write. This also helps RAID5, though less often as RAID5 supports a read-modify-write cycle. For RAID5 the read is performed too early only if the write is not a full 4K aligned write (i.e. no an R5_OVERWRITE). Also clean up a couple of horrible bits of formatting. Reported-by:

commit b2f5d4dc upstream. Forced unmount affects not just the mount namespace but the underlying superblock as well. Restrict forced unmount to the global root user for now. Otherwise it becomes possible a user in a less privileged mount namespace to force the shutdown of a superblock of a filesystem in a more privileged mount namespace, allowing a DOS attack on root.

commit 5a12a07e upstream. Since the commit below, iwldvm sends the FLUSH command to the firmware. All the devices that use iwldvm have a firmware that expects the _v3 version of this command, besides 5150. 5150's latest available firmware still expects a _v2 version of the FLUSH command. This means that since the commit below, we had a mismatch for this specific device only.

commit 445559cd upstream. When dm-bufio sets out to use the bio built into a struct dm_buffer to issue an IO, it needs to call bio_reset after it's done with the bio so that we can free things attached to the bio such as the integrity payload. Therefore, inject our own endio callback to take care of the bio_reset after calling submit_io's end_io callback. Test case: 1. modprobe scsi_debug delay=0 dif=1 dix=199 ato=1 dev_size_mb=300 2. Set up a dm-bufio client, e.g. dm-verity, on the scsi_debug device 3. Repeatedly read metadata and watch kmalloc-192 leak! Signed-off-by:

commit 8bfbe2de upstream. Commit 19e2ad6a ("n_tty: Remove overflow tests from receive_buf() path") moved the increment of read_head into the arguments list of read_buf_addr(). Function calls represent a sequence point in C. Therefore read_head is incremented before the character c is placed in the buffer. Since the circular read buffer is a lock-less design since commit 6d76bd26 ("n_tty: Make N_TTY ldisc receive path lockless"), this creates a race condition that leads to communication errors. This patch modifies the code to increment read_head _after_ the data is placed in the buffer and thus fixes the race for non-SMP machines. To fix the problem for SMP machines, memory barriers must be added in a separate patch. Signed-off-by:

The fix is simply rearrange the call orders in uvc_delete() so that the child is removed before the parent. Bugzilla: https://bugzilla.suse.com/show_bug.cgi?id=897736Reported-and-tested-by:

commit 7ddc6a21 upstream. These functions can be executed on the int3 stack, so kprobes are dangerous. Tracing is probably a bad idea, too. Fixes: b645af2d ("x86_64, traps: Rework bad_iret") Signed-off-by:

commit a33c1ba2 upstream. We currently use num_possible_cpus(), but that breaks on sparc64 where the CPU ID space is discontig. Use nr_cpu_ids as the highest CPU ID instead, so we don't end up reading from invalid memory. Signed-off-by:
