This update fixes the following reports for OFED :

  - 704914: Fixed NFS client over TCP hangs due to packet     loss.

  - 693243: Fixed issue with building lustre against     ofed-devel.

  - 706175: Fix crash on accessing /proc/net/sdpstats

  - 722030: Cannot load ib_ipath

  - 703752: Prevent BUG_ON triggering on congestion

The kernel packages contain the Linux kernel, the core of any Linux operating system.

This update fixes the following security issues :

  - Multiple buffer overflow flaws were found in the Linux     kernel's Management Module Support for Message Passing     Technology (MPT) based controllers. A local,     unprivileged user could use these flaws to cause a     denial of service, an information leak, or escalate     their privileges. (CVE-2011-1494, CVE-2011-1495,     Important)

  - A flaw was found in the Linux kernel's Ethernet bonding     driver implementation. Packets coming in from network     devices that have more than 16 receive queues to a     bonding interface could cause a denial of service.
    (CVE-2011-1581, Important)

  - A flaw was found in the Linux kernel's networking     subsystem. If the number of packets received exceeded     the receiver's buffer limit, they were queued in a     backlog, consuming memory, instead of being discarded. A     remote attacker could abuse this flaw to cause a denial     of service (out-of-memory condition). (CVE-2010-4251,     Moderate)

  - A flaw was found in the Linux kernel's Transparent Huge     Pages (THP) implementation. A local, unprivileged user     could abuse this flaw to allow the user stack (when it     is using huge pages) to grow and cause a denial of     service. (CVE-2011-0999, Moderate)

  - A flaw was found in the transmit methods (xmit) for the     loopback and InfiniBand transports in the Linux kernel's     Reliable Datagram Sockets (RDS) implementation. A local,     unprivileged user could use this flaw to cause a denial     of service. (CVE-2011-1023, Moderate)

  - A flaw in the Linux kernel's Event Poll (epoll)     implementation could allow a local, unprivileged user to     cause a denial of service. (CVE-2011-1082, Moderate)

  - An inconsistency was found in the interaction between     the Linux kernel's method for allocating NFSv4 (Network     File System version 4) ACL data and the method by which     it was freed. This inconsistency led to a kernel panic     which could be triggered by a local, unprivileged user     with files owned by said user on an NFSv4 share.
    (CVE-2011-1090, Moderate)

  - A missing validation check was found in the Linux     kernel's mac_partition() implementation, used for     supporting file systems created on Mac OS operating     systems. A local attacker could use this flaw to cause a     denial of service by mounting a disk that contains     specially crafted partitions. (CVE-2011-1010, Low)

  - A buffer overflow flaw in the DEC Alpha OSF partition     implementation in the Linux kernel could allow a local     attacker to cause an information leak by mounting a disk     that contains specially crafted partition tables.
    (CVE-2011-1163, Low)

  - Missing validations of null-terminated string data     structure elements in the do_replace(),     compat_do_replace(), do_ipt_get_ctl(),     do_ip6t_get_ctl(), and do_arpt_get_ctl() functions could     allow a local user who has the CAP_NET_ADMIN capability     to cause an information leak. (CVE-2011-1170,     CVE-2011-1171, CVE-2011-1172, Low)

This update also fixes several hundred bugs and adds enhancements.

The system must be rebooted for this update to take effect.
