Cross-References:   CVE-2013-2206
Affected Products:
                    SUSE Linux Enterprise Real Time 11 SP2

   An update that solves one vulnerability and has 42 fixes is
   now available. It includes one version update.


   The SUSE Linux Enterprise 11 Service Pack 2 kernel for
   RealTime was updated  to version 3.0.101 and also includes
   various other bug and security fixes.

   The following features have been added:

   * Drivers: hv: Support handling multiple VMBUS versions
   * Drivers: hv: Save and export negotiated vmbus version
   * Drivers: hv: Move vmbus version definitions to
   hyperv.h (FATE#314665).

   The following security issue has been fixed:

   * CVE-2013-2206: The sctp_sf_do_5_2_4_dupcook function
   in net/sctp/sm_statefuns.c in the SCTP implementation in
   the Linux kernel did not properly handle associations
   during the processing of a duplicate COOKIE ECHO chunk,
   which allowed remote attackers to cause a denial of service
   (NULL pointer dereference and system crash) or possibly
   have unspecified other impact via crafted SCTP traffic.

   The following non-security bugs have been fixed:

   * mm: Do not walk all of system memory during show_mem
   (Reduce tasklist_lock hold times (bnc#821259)).
   * mm, memcg: introduce own oom handler to iterate only
   over its own threads.
   * mm, memcg: move all oom handling to memcontrol.c.
   * mm, oom: avoid looping when chosen thread detaches
   its mm.
   * mm, oom: fold oom_kill_task() into oom_kill_process().
   * mm, oom: introduce helper function to process threads
   during scan.
   * mm, oom: reduce dependency on tasklist_lock.
   * kernel: sclp console hangs (bnc#841498, LTC#95711).
   * splice: fix racy pipe->buffers uses (bnc#827246).
   * blktrace: fix race with open trace files and
   directory removal (bnc#832292).
   * Set proper SK when CK_COND is set (bnc#833588).
   * iommu/vt-d: add quirk for broken interrupt remapping
   on 55XX chipsets (bnc#844513).
   * x86/iommu/vt-d: Expand interrupt remapping quirk to
   cover x58 chipset (bnc#844513).
   * iommu/vt-d: Only warn about broken interrupt
   remapping (bnc#844513).
   * iommu: Remove stack trace from broken irq remapping
   warning (bnc#844513).
   * intel-iommu: Fix leaks in pagetable freeing
   * softirq: reduce latencies (bnc#797526).
   * softirq: Fix lockup related to stop_machine being
   stuck in __do_softirq (bnc#797526).
   * bounce: Bounce memory pool initialisation (bnc#836347)
   * writeback: Do not sync data dirtied after sync start
   * config//debug: Enable FSCACHE_DEBUG and
   CACHEFILES_DEBUG (bnc#837372).
   * Fixed Xen guest freezes (bnc#829682, bnc#842063).
   * SUNRPC: close a rare race in xs_tcp_setup_socket
   * NFS: make nfs_flush_incompatible more generous
   * NFS: don't try to use lock state when we hold a
   delegation (bnc#831029).
   * nfs_lookup_revalidate(): fix a leak (bnc#828894).
   * fs: do_add_mount()/umount -l races (bnc#836801).
   * cifs: fill TRANS2_QUERY_FILE_INFO ByteCount fields
   * cifs: Fix EREMOTE errors encountered on DFS links
   * xfs: growfs: use uncached buffers for new headers
   * xfs: avoid double-free in xfs_attr_node_addname.
   * xfs: Check the return value of xfs_buf_get()
   * iscsi: don't hang in endless loop if no targets
   present (bnc#841094).
   * reiserfs: fix race with flush_used_journal_lists and
   flush_journal_list (bnc#837803).
   * md: Throttle number of pending write requests in
   md/raid10 (bnc#833858).
