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. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (77 commits) skbuff: skb_copy_ubufs must release uarg even without user frags skbuff: orphan frags before zerocopy clone net: reevalulate autoflowlabel setting after sysctl setting openvswitch: Fix pop_vlan action for double tagged frames ipv6: Honor specified parameters in fibmatch lookup bpf: do not allow root to mangle valid pointers selftests/bpf: add tests for recent bugfixes bpf: fix integer overflows bpf: don't prune branches when a scalar is replaced with a pointer bpf: force strict alignment checks for stack pointers bpf: fix missing error return in check_stack_boundary() bpf: fix 32-bit ALU op verification bpf: fix incorrect tracking of register size truncation bpf: fix incorrect sign extension in check_alu_op() bpf/verifier: fix bounds calculation on BPF_RSH ipv4: Fix use-after-free when flushing FIB tables s390/qeth: fix error handling in checksum cmd callback tipc: remove joining group member from congested list selftests: net: Adding config fragment CONFIG_NUMA=y nfp: bpf: keep track of the offloaded program ...
