Pull networking fixes from David Miller:
"A little more than usual this time around. Been travelling, so that is
part of it.
Anyways, here are the highlights:
1) Deal with memcontrol races wrt. listener dismantle, from Eric
Dumazet.
2) Handle page allocation failures properly in nfp driver, from Jaku
Kicinski.
3) Fix memory leaks in macsec, from Sabrina Dubroca.
4) Fix crashes in pppol2tp_session_ioctl(), from Guillaume Nault.
5) Several fixes in bnxt_en driver, including preventing potential
NVRAM parameter corruption from Michael Chan.
6) Fix for KRACK attacks in wireless, from Johannes Berg.
7) rtnetlink event generation fixes from Xin Long.
8) Deadlock in mlxsw driver, from Ido Schimmel.
9) Disallow arithmetic operations on context pointers in bpf, from
Jakub Kicinski.
10) Missing sock_owned_by_user() check in sctp_icmp_redirect(), from
Xin Long.
11) Only TCP is supported for sockmap, make that explicit with a
check, from John Fastabend.
12) Fix IP options state races in DCCP and TCP, from Eric Dumazet.
13) Fix panic in packet_getsockopt(), also from Eric Dumazet.
14) Add missing locked in hv_sock layer, from Dexuan Cui.
15) Various aquantia bug fixes, including several statistics handling
cures. From Igor Russkikh et al.
16) Fix arithmetic overflow in devmap code, from John Fastabend.
17) Fix busted socket memory accounting when we get a fault in the tcp
zero copy paths. From Willem de Bruijn.
18) Don't leave opt->tot_len uninitialized in ipv6, from Eric Dumazet"
