John Fastabend (6):
bpf: sockmap, error path can not release psock in multi-map case
bpf: sockmap, hash table is RCU so readers do not need locks
bpf: fix sk_skb programs without skb->dev assigned
bpf: sockhash, disallow bpf_tcp_close and update in parallel
bpf: sockmap, consume_skb in close path
bpf: sockmap, convert bpf_compute_data_pointers to bpf_*_sk_skb
Magnus Karlsson (4):
xsk: fix potential lost completion message in SKB path
xsk: frame could be completed more than once in SKB path
samples/bpf: deal with EBUSY return code from sendmsg in xdpsock sample
xsk: fix potential race in SKB TX completion code
Mauricio Vasquez B (1):
bpf: hash map: decrement counter on error
Taeung Song (4):
samples/bpf: add missing <linux/if_vlan.h>
samples/bpf: Check the result of system()
samples/bpf: Check the error of write() and read()
samples/bpf: add .gitignore file
