Security update for the Linux Kernel (important)

The openSUSE 13.2 kernel was updated to receive various security and
bugfixes.

Following security bugs were fixed:

• CVE-2015-3290: arch/x86/entry/entry_64.S in the Linux kernel on the
  x86_64 platform improperly relied on espfix64 during nested NMI
  processing, which allowed local users to gain privileges by triggering
  an NMI within a certain instruction window (bnc#937969)
• CVE-2015-0272: It was reported that it’s possible to craft a Router
  Advertisement message which will bring the receiver in a state where new
  IPv6 connections will not be accepted until correct Router Advertisement
  message received. (bsc#944296).
• CVE-2015-5283: The sctp_init function in net/sctp/protocol.c in the
  Linux kernel had an incorrect sequence of protocol-initialization steps,
  which allowed local users to cause a denial of service (panic or memory
  corruption) by creating SCTP sockets before all of the steps have
  finished (bnc#947155).
• CVE-2015-1333: Memory leak in the __key_link_end function in
  security/keys/keyring.c in the Linux kernel allowed local users to cause
  a denial of service (memory consumption) via many add_key system calls
  that refer to existing keys. (bsc#938645)
• CVE-2015-5707: Integer overflow in the sg_start_req function in
  drivers/scsi/sg.c in the Linux kernel allowed local users to cause a
  denial of service or possibly have unspecified other impact via a large
  iov_count value in a write request. (bsc#940338)
• CVE-2015-2925: An attacker could potentially break out of a namespace
  or container, depending on if he had specific rights in these
  containers. (bsc#926238).
• CVE-2015-7872: A vulnerability in keyrings garbage collector allowed a
  local user to trigger an oops was found, caused by using request_key()
  or keyctl request2. (bsc#951440)

The following non-security bugs were fixed:

• input: evdev - do not report errors form flush() (bsc#939834).
• NFSv4: Recovery of recalled read delegations is broken (bsc#942178).
• apparmor: temporary work around for bug while unloading policy
  (boo#941867).
• config/x86_64/ec2: Align CONFIG_STRICT_DEVMEM CONFIG_STRICT_DEVMEM is
  enabled in every other kernel flavor, so enable it for x86_64/ec2 as
  well.
• kernel-obs-build: add btrfs to initrd This is needed for kiwi builds.
• mmc: card: Do not access RPMB partitions for normal read/write
  (bnc#941104).
• netback: coalesce (guest) RX SKBs as needed (bsc#919154).
• rpm/kernel-obs-build.spec.in: Add virtio_rng to the initrd. This allows
  to feed some randomness to the OBS workers.
• xfs: Fix file type directory corruption for btree directories
  (bsc#941305).
• xfs: ensure buffer types are set correctly (bsc#941305).
• xfs: inode unlink does not set AGI buffer type (bsc#941305).
• xfs: set buf types when converting extent formats (bsc#941305).
• xfs: set superblock buffer type correctly (bsc#941305).
• xhci: Add spurious wakeup quirk for LynxPoint-LP controllers
  (bnc#951195).
