  script_tag(name:"insight", value:"The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various security and bugfixes.

This new feature was added:

- Btrfs: Remove empty block groups in the background

The following security bugs were fixed:

- CVE-2018-3665: Prevent disclosure of FPU registers (including XMM and AVX
 registers) between processes. These registers might contain encryption keys
 when doing SSE accelerated AES enc/decryption (bsc#1087086)

The following non-security bugs were fixed:

- ALSA: timer: Fix pause event notification (bsc#973378).
- Btrfs: Avoid trucating page or punching hole in a already existed hole (bsc#1088998).
- Btrfs: Avoid truncate tailing page if fallocate range does not exceed inode size (bsc#1094424).
- Btrfs: Fix lost-data-profile caused by auto removing bg.
- Btrfs: Fix misuse of chunk mutex
- Btrfs: Fix out-of-space bug (bsc#1089231).
- Btrfs: Set relative data on clear btrfs_block_group_cache->pinned.
- Btrfs: Use ref_cnt for set_block_group_ro() (bsc#1089239).
- Btrfs: add alloc_fs_devices and switch to it (bsc#1089205).
- Btrfs: add btrfs_alloc_device and switch to it (bsc#1089204).
- Btrfs: add missing discards when unpinning extents with -o discard.
- Btrfs: add missing inode update when punching hole (bsc#1089006).
- Btrfs: add support for asserts (bsc#1089207).
- Btrfs: avoid syncing log in the fast fsync path when not necessary (bsc#1089010).
- Btrfs: btrfs_issue_discard ensure offset/length are aligned to sector boundaries.
- Btrfs: check pending chunks when shrinking fs to avoid corruption (bsc#1089235).
- Btrfs: cleanup backref search commit root flag stuff (bsc#1089200).
- Btrfs: delete chunk allocation attemp when setting block group ro.
- Btrfs: do not leak transaction in btrfs_sync_file() (bsc#1089210).
- Btrfs: do not mix the ordered extents of all files together during logging the inodes (bsc#1089214).
- Btrfs: do not remove extents and xattrs when logging new names (bsc#1089005).
- Btrfs: eliminate races in worker stopping code (bsc#1089211).
- Btrfs: ensure deletion from pinned_chunks list is protected.
- Btrfs: explictly delete unused block groups in close_ctree and ro-remount.
- Btrfs: fix -ENOSPC on block group removal.
- Btrfs: fix -ENOSPC when finishing block group creation.
- Btrfs: fix BUG_ON in btrfs_orphan_add() when delete unused block group.
- Btrfs: fix NULL pointer crash when running balance and scrub concurrently (bsc#1089220).
- Btrfs: fix chunk allocation regression leading to transaction abort (bsc#1089236).
- Btrfs: fix crash caused by block group removal.
- Btrfs: fix data loss in the fast fsync path (bsc#1089007).
- Btrfs: fix deadlock caused by fsync when logging directory entries (bsc#1093194).
- Btrfs: fix directory inconsistency after fsync log replay (bsc#1089001).
- Btrfs: fix directory recovery from fsync log (bsc#1088999).
- Btrfs: fix empty symlink after creating symlink and fsync parent dir (bsc#1093195).
