Linux Kernel: Security/Bugfix update to 2.6.27.29

The SUSE Linux Enterprise 11 Kernel was updated to 2.6.27.29 fixing various bugs and security issues. Following security issues were fixed: CVE-2009-2692: A missing NULL pointer check in the socket sendpage function can be used by local attackers to gain root privileges. CVE-2009-2406: A kernel stack overflow when mounting eCryptfs filesystems in parse_tag_11_packet() was fixed. Code execution might be possible of ecryptfs is in use. CVE-2009-2407: A kernel heap overflow when mounting eCryptfs filesystems in parse_tag_3_packet() was fixed. Code execution might be possible of ecryptfs is in use. The compiler option -fno-delete-null-pointer-checks was added to the kernel build, and the -fwrapv compiler option usage was fixed to be used everywhere. This works around the compiler removing checks too aggressively. CVE-2009-1389: A crash in the r8169 driver when receiving large packets was fixed. This is probably exploitable only in the local network. No CVE yet: A sigaltstack kernel memory disclosure was fixed. The NULL page protection using mmap_min_addr was enabled (was disabled before). This update also adds the Microsoft Hyper-V drivers from upstream.
