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:

* Attempting to use the request_key() function to add a key into a revoked keyring was causing a resource leak in the kernel error path. Keys which were allocated and then failed became stuck in memory and were impossible for the garbage collector to remove. With this update, the reference count on failed keys correctly reaches 0 in this situation, allowing the garbage collector to remove them.
* A bug in the ipr driver on IBM Power Systems (ppc64) could result in backwards memory buffer indexing and cause a kernel crash when running the Hardware Test Exerciser (HTX) test suite. With this update, ipr memory buffer indexing uses a bit mask operation instead of modulo, causing low bits to be masked off so that backwards indexing is no longer possible.
* Resetting an ixgbe or vmxnet3 adapter while sending a message over netconsole or netpoll at the same time could previously cause a kernel crash. This update adds mutual exclusion between the core adapter reset path and the netpoll transmit path, and the crash no longer occurs.
* When removing a directory while a reference was held to that directory by a reference to a negative child dentry, the directory dentry was previously not killed. In addition, once the negative child dentry was killed, unlinked and unused dentry was present in the cache. As a consequence, deadlock could be caused by forcing the dentry eviction while the file system in question was frozen. With this update, all unused dentries are unhashed and evicted just after a successful directory removal, which avoids the deadlock, and the system no longer hangs in the aforementioned scenario.
* Previously, an unusual forking pattern could cause the anon_vma_chain and anon_vma slab memory to grow infinitely even though the number of processes involved stayed low. As a consequence, a kernel panic occurred. The provided patch adds a heuristic which reuses existing anon_vma instead of forking a new one and adds the anon_vma-
