kernel-2.6.32-642.13.1.el6

The kernel package contains the Linux kernel (vmlinuz), the core of any
Linux operating system. The kernel handles the basic functions
of the operating system: memory allocation, process allocation, device
input and output, etc.

Security issues fixed with this release:

CVE-2016-4998
The IPT_SO_SET_REPLACE setsockopt implementation in the netfilter
subsystem in the Linux kernel before 4.6 allows local users to cause a
denial of service (out-of-bounds read) or possibly obtain sensitive
information from kernel heap memory by leveraging in-container root
access to provide a crafted offset value that leads to crossing a
ruleset blob boundary.
CVE-2016-6828
The tcp_check_send_head function in include/net/tcp.h in the Linux
kernel before 4.7.5 does not properly maintain certain SACK state
after a failed data copy, which allows local users to cause a denial
of service (tcp_xmit_retransmit_queue use-after-free and system crash)
via a crafted SACK option.
CVE-2016-7117
Use-after-free vulnerability in the __sys_recvmmsg function in
net/socket.c in the Linux kernel before 4.5.2 allows remote attackers
to execute arbitrary code via vectors involving a recvmmsg system call
that is mishandled during error processing.

Fixed bugs:

* When parallel NFS returned a file layout, a kernel crash sometimes occurred. This update removes the call to the BUG_ON() function from a code path of a client that returns the file layout. As a result, the kernel no longer crashes in the described situation.
* When a guest virtual machine (VM) on Microsoft Hyper-V was set to crash on a Nonmaskable Interrupt (NMI) that was injected from the host, this VM became unresponsive and did not create the vmcore dump file. This update applies a set of patches to the Virtual Machine Bus kernel driver (hv_vmbus) that fix this bug. As a result, the VM now first creates and saves the vmcore dump file and then reboots.
* From Asianux Server 4.6 to 6.8, the IPv6 routing cache occasionally showed incorrect values. This update fixes the DST_NOCOUNT mechanism, and the IPv6 routing cache now shows correct values.
* When using the ixgbe driver and the software Fibre Channel over Ethernet (FCoE) stack, suboptimal performance in some cases occurred on systems with a large number of CPUs. This update fixes the fc_exch_alloc() function to try all the available exchange managers in the list for an available exchange ID. This change avoids failing allocations, which previously led to the host busy status.
* When the vmwgfx kernel module loads, it overrides the boot resolution automatically. Consequently, users were not able to change the resolution by manual setting of the kernel's 'vga=' parameter in the /boot/grub/grub.conf file. This update adds the 'nomodeset' parameter, which can be set in the /boot/grub/grub.conf file. The 'nomodeset' parameter allows the users to prevent the vmwgfx driver from loading. As a result, the setting of the 'vga=' parameter works as expected, in case that vmwgfx does not load.
* When Asianux Server 4.8 was booted on SMBIOS 3.0 based systems, Desktop Management Interface (DMI) information, which is referenced by several applications, such as NEC server's memory RAS utility, was missing entries in the sysfs virtual file system. This update fixes the underlying source code, and sysfs now shows the DMI information as expected.
* Previously, bonding mode active backup and the propagation of the media access control (MAC) address to a VLAN interface did not work in Asianux Server 4.8, when the fail_over_mac bonding parameter was set to fail_over_mac=active. With this update, the underlying source code has been fixed so that the VLANs continue inheriting the MAC address of the active physical interface until the VLAN MAC address is explicitly set to any value. As a result, IPv6 EUI64 addresses for the VLAN can reflect any changes to the MAC address of the physical interface, and Duplicate Address Detection (DAD) behaves as expected.
