Pull networking fixes from David Miller:

 1) Don't race in IPSEC dumps, from Yuejie Shi.

 2) Verify lengths properly in IPSEC reqeusts, from Herbert Xu.

 3) Fix out of bounds access in ipv6 segment routing code, from David
    Lebrun.

 4) Don't write into the header of cloned SKBs in smsc95xx driver, from
    James Hughes.

 5) Several other drivers have this bug too, fix them. From Eric
    Dumazet.

 6) Fix access to uninitialized data in TC action cookie code, from
    Wolfgang Bumiller.

 7) Fix double free in IPV6 segment routing, again from David Lebrun.

 8) Don't let userspace set the RTF_PCPU flag, oops. From David Ahern.

 9) Fix use after free in qrtr code, from Dan Carpenter.

10) Don't double-destroy devices in ip6mr code, from Nikolay
    Aleksandrov.

11) Don't pass out-of-range TX queue indices into drivers, from Tushar
    Dave.
