Pull networking fixes from David Miller"
"What's a holiday weekend without some networking bug fixes? [1]
1) Fix some eBPF JIT bugs wrt. SKB pointers across helper function
calls, from Daniel Borkmann.
2) Fix regression from errata limiting change to marvell PHY driver,
from Zhao Qiang.
3) Fix u16 overflow in SCTP, from Xin Long.
4) Fix potential memory leak during bridge newlink, from Nikolay
Aleksandrov.
5) Fix BPF selftest build on s390, from Hendrik Brueckner.
6) Don't append to cfg80211 automatically generated certs file,
always write new ones from scratch. From Thierry Reding.
7) Fix sleep in atomic in mac80211 hwsim, from Jia-Ju Bai.
8) Fix hang on tg3 MTU change with certain chips, from Brian King.
9) Add stall detection to arc emac driver and reset chip when this
happens, from Alexander Kochetkov.
10) Fix MTU limitng in GRE tunnel drivers, from Xin Long.
11) Fix stmmac timestamping bug due to mis-shifting of field. From
Fredrik Hallenberg.
12) Fix metrics match when deleting an ipv4 route. The kernel sets
some internal metrics bits which the user isn't going to set when
it makes the delete request. From Phil Sutter.
13) mvneta driver loop over RX queues limits on "txq_number" :-) Fix
from Yelena Krivosheev.
14) Fix double free and memory corruption in get_net_ns_by_id, from
Eric W. Biederman.
15) Flush ipv4 FIB tables in the reverse order. Some tables can share
their actual backing data, in particular this happens for the MAIN
and LOCAL tables. We have to kill the LOCAL table first, because
it uses MAIN's backing memory. Fix from Ido Schimmel.
16) Several eBPF verifier value tracking fixes, from Edward Cree, Jann
Horn, and Alexei Starovoitov.
17) Make changes to ipv6 autoflowlabel sysctl really propagate to
sockets, unless the socket has set the per-socket value
explicitly. From Shaohua Li.
18) Fix leaks and double callback invocations of zerocopy SKBs, from
Willem de Bruijn"
[1] Is this a trick question? "Relaxing"? "Quiet"? "Fine"? - Linus.
