Kernel: filter: prevent nla extensions to peek beyond the end of the message

The BPFSANCNLATTRNEST extension implementation in the skrunfilter function in net/core/filter.c in the Linux kernel through 3.14.3 uses the reverse order in a certain subtraction, which allows local users to cause a denial of service over-read and system crash via crafted BPF instructions. NOTE:...
