Revision 90a5a895cc8b284ac522757a01de15e36710c2b9 authored by Linus Torvalds on 23 March 2015, 17:16:13 UTC, committed by Linus Torvalds on 23 March 2015, 17:16:13 UTC
Pull networking fixes from David Miller:
1) Validate iov ranges before feeding them into iov_iter_init(), from
Al Viro.
2) We changed copy_from_msghdr_from_user() to zero out the msg_namelen
is a NULL pointer is given for the msg_name. Do the same in the
compat code too. From Catalin Marinas.
3) Fix partially initialized tuples in netfilter conntrack helper, from
Ian Wilson.
4) Missing continue; statement in nft_hash walker can lead to crashes,
from Herbert Xu.
5) tproxy_tg6_check looks for IP6T_INV_PROTO in ->flags instead of
->invflags, fix from Pablo Neira Ayuso.
6) Incorrect memory account of TCP FINs can result in negative socket
memory accounting values. Fix from Josh Hunt.
7) Don't allow virtual functions to enable VLAN promiscuous mode in
be2net driver, from Vasundhara Volam.
