ploop: warn if a discard request is issued for the ploop header.
ve: detect removal of additional system libraries in the containers to simplify debugging.
Potential leak of a reference counter for a memory cgroup in memcg_expand_shrinker_maps().
Potential corruption of ploop images due to a race between the truncation thread and resize operations.
ve: make it easier to analyze removal of system libraries in the containers.
xfs: potential denial of service caused by missing unlock operation in xfs_setattr_nonsize().It was discovered that xfs_setattr_nonsize() would not unlock 'ILOCK' lock if the user or group were out of their disk quota. As a result, any subsequent operation, which needed to take 'ILOCK', would get stuck, leading to a denial of service.https://access.redhat.com/security/cve/cve-2019-15538
nf_tables: kernel crash in nft_rbtree_lookup().
ploop: holes in raw ploop images were handled incorrectly.
Kernel crash due to out-of-bounds memory accesses in process_vm_readv().It was discovered that the implementation of process_vm_readv() system call could try to access memory outside of the structures it was processing in certain cases. A local unprivileged user could use this vulnerability to crash the system.
quotaoff operation executed in a container could get stuck in D state.
Certain operations with an empty ploop image could lead to its unexpected growth.
Incomplete fix for PSBM-100575: reading of /proc/bc/resources line by line would never end.
memcg: memory corruption caused by writing beyond the end of shrinker_map structure.
ixgbe: lots of warnings in the system log due to incorrect check for firmware errors.
ploop: kernel crashes when processing discard requests for ploop images in raw format.
scsi: printing lots of messages about rejected I/O causes a hard lockup and a kernel crash.
Kernel crash in shrink_slab() when trying to mount an image with a broken ext4 file system.
Reading of /proc/bc/resources line by line would never end: no end of file was reported.
Potential kernel crash in __radix_tree_insert() when fscache is used for NFS mounts.
sunrpc: potential kernel crash in bc_svc_process().
A bug in ploop prevented recovery of corrupted ploop images.
The minimum amount of reserved free memory (vm.min_free_kbytes) was set too high by default.
kvm: potential system hang due to an error in mmu_shrink_scan().
Processes could get stuck in copy_net_ns() forever.
