Hi David, hi Jakub, hi Paolo, hi Eric,

The following pull-request contains BPF updates for your *net-next* tree.

We've added 10 non-merge commits during the last 15 day(s) which contain
a total of 10 files changed, 222 insertions(+), 190 deletions(-).

The main changes are:

1) Add TCP_BPF_SOCK_OPS_CB_FLAGS to bpf_*sockopt() to address the case when
   long-lived sockets miss a chance to set additional callbacks if a sockops
   program was not attached early in their lifetime, from Alan Maguire.

2) Add a batch of BPF selftest improvements which fix a few bugs and add missing
   features to improve the test coverage of sockmap/sockhash, from Michal Luczaj.

3) Fix a false-positive Smatch-reported off-by-one in tcp_validate_cookie() which
   is part of the test_tcp_custom_syncookie BPF selftest, from Kuniyuki Iwashima.

4) Fix the flow_dissector BPF selftest which had a bug in IP header's tot_len
   calculation doing subtraction after htons() instead of inside htons(), from
   Asbjørn Sloth Tønnesen.
