Revision 1ee18329fae936089c6c599250ae92482ff2b81f authored by Linus Torvalds on 10 February 2017, 22:44:49 UTC, committed by Linus Torvalds on 10 February 2017, 22:44:49 UTC
Pull networking fixes from David Miller:
1) If the timing is wrong we can indefinitely stop generating new ipv6
temporary addresses, from Marcus Huewe.
2) Don't double free per-cpu stats in ipv6 SIT tunnel driver, from Cong
Wang.
3) Put protections in place so that AF_PACKET is not able to submit
packets which don't even have a link level header to drivers. From
Willem de Bruijn.
4) Fix memory leaks in ipv4 and ipv6 multicast code, from Hangbin Liu.
5) Don't use udp_ioctl() in l2tp code, UDP version expects a UDP socket
and that doesn't go over very well when it is passed an L2TP one.
Fix from Eric Dumazet.
6) Don't crash on NULL pointer in phy_attach_direct(), from Florian
Fainelli.
