Description: 

The kernel package contains the Linux kernel (vmlinuz), the core of any
Linux operating system. The kernel handles the basic functions
of the operating system: memory allocation, process allocation, device
input and output, etc.

Fixed bugs:

* The memory used by the defragmentation engine is accounted for per CPU. However, on systems with numerous CPUs, the per-CPU caches could deviate from reality, thus causing the defragmentation engine to discard old fragments too early. This update adds a fix to minimize this discrepancy, and old fragments are now discarded in time.
* Previously, reloading or removing edac modules on a system using the i7core_edac module could lead to a number of returned warning messages and a subsequent kernel crash. The underlying source code has been patched, and the kernel no longer crashes when operating with edac modules.
* Due to a regression, packets counter detected only the number of normally processed completions (packets), not the erroneous ones. As these packets were thus never acknowledged, the firmware kept returning interrupt requests (IRQs). A patch has been provided to fix this bug, and all packets are now counted as expected.
* Unlikely conditions in the nfs_clear_inode() function can cause a kernel panic due to the use of the BUG_ON() macro. An upstream patch replacing the BUG_ON() macro with WARN_ON_ONCE() in this function has been provided to avoid this panic and the kernel panic no longer occurs in this situation.
* Previously, a bridge interface could exist on top of a bonded interface, which was above a physical interface with the large receive offload (LRO) flag still on. Bridge interfaces are incompatible with LRO enabled on any underlying devices, which caused network communications on the bridge, such as that from a Virtual Machine (VM) to fail to function properly. This update makes sure devices underneath a bridge all get LRO disabled, and a VM now connects via a bridged interface successfully.
* During a KVM guest shutdown, if a virtio device generated interrupts, the virtio driver sometimes could not correctly handle or clear the interrupt. As a consequence, the system became busy, continuously processing the same interrupt, leading to an incomplete shutdown of the KVM guest. This bug has been fixed, and the guest now shuts down properly.
* After adjusting the extent size with the xfs_fio utility and running the fio command with the configuration file provided, the XFS file system became corrupted. This update makes sure the extent size hints can round up extents past the maximum extent length, and the XFS file system now preserves fio operations.
* At a process or thread exit, when the Linux kernel undoes any SysV semaphore operations done previously (the ones done using semop with the SEM_UNDO flag), there was a possible flaw and race with another process or thread removing the same semaphore set where the operations occurred, leading to possible use of in-kernel-freed memory and then to possible unpredictable behaviour. This bug could be noticed with software which uses IPC SysV semaphores, such as IBM DB2, which for example in certain cases could lead to a situation where its processes or utilities could get incorrectly stalled in some IPC semaphore operation or syscall after the race or problem happened. A patch has been provided to fix this bug, and the kernel now behaves as expected in the aforementioned scenario.
* On a system with a bonded interface, the user could not specify a custom MAC address for the bond. A patch has been provided to fix this bug, and custom MAC addresses can be specified again in the aforementioned situation.
