Pull networking fixes from David Miller:
"Sorry I let so much accumulate, I was in Buffalo and wanted a few
things to cook in my tree for a while before sending to you. Anyways,
it's a lot of little things as usual at this stage in the game"
1) Make bonding MAINTAINERS entry reflect reality, from Andy
Gospodarek.
2) Fix accidental sock_put() on timewait mini sockets, from Eric
Dumazet.
3) Fix crashes in l2tp due to mis-handling of ipv4 mapped ipv6
addresses, from François CACHEREUL.
4) Fix heap overflow in __audit_sockaddr(), from the eagle eyed Dan
Carpenter.
5) tcp_shifted_skb() doesn't take handle FINs properly, from Eric
Dumazet.
6) SFC driver bug fixes from Ben Hutchings.
7) Fix TX packet scheduling wedge after channel change in ath9k driver,
from Felix Fietkau.
8) Fix user after free in BPF JIT code, from Alexei Starovoitov.
9) Source address selection test is reversed in
__ip_route_output_key(), fix from Jiri Benc.
10) VLAN and CAN layer mis-size netlink attributes, from Marc
Kleine-Budde.
11) Fix permission checks in sysctls to use current_euid() instead of
current_uid(). From Eric W Biederman.
12) IPSEC policies can go away while a timer is still pending for them,
add appropriate ref-counting to fix, from Steffen Klassert.
13) Fix mis-programming of FDR and RMCR registers on R8A7740 sh_eth
chips, from Nguyen Hong Ky and Simon Horman.
14) MLX4 forgets to DMA unmap pages on RX, fix from Amir Vadai.
15) IPV6 GRE tunnel MTU upper limit is miscalculated, from Oussama
Ghorbel.
16) Fix typo in fq_change(), we were assigning "initial quantum" to
"quantum". From Eric Dumazet.
17) Set a more appropriate sk_pacing_rate for non-TCP sockets, otherwise
FQ packet scheduler does not pace those flows properly. Also from
Eric Dumazet.
18) rtlwifi miscalculates packet pointers, from Mark Cave-Ayland.
19) l2tp_xmit_skb() can be called from process context, not just softirq
context, so we must always make sure to BH disable around it. From
Eric Dumazet.
20) On qdisc reset, we forget to purge the RB tree of SKBs in netem
packet scheduler. From Stephen Hemminger.
21) Fix info leak in farsync WAN driver ioctl() handler, from Dan
Carpenter and Salva Peiró.
22) Fix PHY reset and other issues in dm9000 driver, from Nikita
Kiryanov and Michael Abbott.
23) When hardware can do SCTP crc32 checksums, we accidently don't
disable the csum offload when IPSEC transformations have been
applied. From Fan Du and Vlad Yasevich.
24) Tail loss probing in TCP leaves the socket in the wrong congestion
avoidance state. From Yuchung Cheng.
25) In CPSW driver, enable NAPI before interrupts are turned on, from
Markus Pargmann.
26) Integer underflow and dual-assignment in YAM hamradio driver, from
Dan Carpenter.
27) If we are going to mangle a packet in tcp_set_skb_tso_segs() we must
unclone it. This fixes various hard to track down crashes in
drivers where the SKBs ->gso_segs was changing right from underneath
the driver during TX queueing. From Eric Dumazet.
28) Fix the handling of VLAN IDs, and in particular the special IDs 0
and 4095, in the bridging layer. From Toshiaki Makita.
29) Another info leak, this time in wanxl WAN driver, from Salva Peiró.
30) Fix race in socket credential passing, from Daniel Borkmann.
31) WHen NETLABEL is disabled, we don't validate CIPSO packets properly,
from Seif Mazareeb.
32) Fix identification of fragmented frames in ipv4/ipv6 UDP
Fragmentation Offload output paths, from Jiri Pirko.
33) Virtual Function fixes in bnx2x driver from Yuval Mintz and Ariel
Elior.
34) When we removed the explicit neighbour pointer from ipv6 routes a
slight regression was introduced for users such as IPVS, xt_TEE, and
raw sockets. We mix up the users requested destination address with
the routes assigned nexthop/gateway. From Julian Anastasov and
Simon Horman.
35) Fix stack overruns in rt6_probe(), the issue is that can end up
doing two full packet xmit paths at the same time when emitting
neighbour discovery messages. From Hannes Frederic Sowa.
36) davinci_emac driver doesn't handle IFF_ALLMULTI correctly, from
Mariusz Ceier.
37) Make sure to set TCP sk_pacing_rate after the first legitimate RTT
sample, from Neal Cardwell.
38) Wrong netlink attribute passed to xfrm_replay_verify_len(), from
Steffen Klassert.
