Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller:
"Some more fixes trickled in over the past few days:
1) PIM device names can overflow the IFNAMSIZ buffer unless we
properly limit the allowed indexes, fix from Eric Dumazet.
2) Under heavy load we can OOPS in icmp reply processing due to an
unchecked inet_putpeer() call. Fix from Neal Cardwell.
3) SCTP round trip calculations need to use 64-bit math to avoid
overflows, fix from Schoch Christian.
4) Fix a memory leak and an error return flub in SCTP and IRDA
triggerable by userspace. Fix from Tommi Rantala and found by the
syscall fuzzer (trinity).
5) MLX4 driver gives bogus size to memcpy() call, fix from Amir
Vadai.
6) Fix length calculation in VHOST descriptor translation, from
Michael S Tsirkin.
7) Ambassador ATM driver loops forever while loading firmware, fix
from Dan Carpenter.
8) Over MTU packets in openvswitch warn about wrong device, fix from
Jesse Gross.
9) Netfilter IPSET's netlink code can overrun a string buffer because
it's not properly limited to IFNAMSIZ. Fix from Florian Westphal.
10) PCAN USB driver sets wrong timestamp in SKB, from Oliver Hartkopp.
11) Make sure the RX ifindex always has a valid value in the CAN BCM
driver, even if we haven't received a frame yet. Fix also from
Oliver Hartkopp."
