Security update for kernel live patch 2

This kernel live patch for Linux Kernel 3.12.36-38.1 fixes security issues and bugs:

Security issues fixed:
- CVE-2015-8539: A negatively instantiated user key could have been used
by a local user to leverage privileges (bnc#958601).

  • CVE-2015-6937: A NULL pointer dereference flaw was found in the Reliable
    Datagram Sockets (RDS) implementation allowing a local user to cause
    system DoS. A verification was missing that the underlying transport
    exists when a connection was created. (bsc#953052)

  • CVE-2015-7990: RDS: Verify the underlying transport exists before
    creating a connection, preventing possible DoS (bsc#953052).

  • CVE-2015-7872: Possible crash when trying to garbage collect an
    uninstantiated keyring (bsc#951542).

  • CVE-2015-2925: The prepend_path function in fs/dcache.c in the Linux
    kernel did not properly handle rename actions inside a bind mount, which
    allowed local users to bypass an intended container protection mechanism
    by renaming a directory, related to a 'double-chroot attack (bnc#951625).

Non-security bugfix were also done:
- xfs: Fix lost direct IO write in the last block (bsc#954005).
- simple fix in kallsyms initialization (bsc#940342 bsc#916225)
