Subject: [PATCH net 0/2] Two BPF fixes
Date: Mon, 17 Apr 2017 03:12:05 +0200 [thread overview]
Message-ID: <cover.1492390940.git.daniel@iogearbox.net> (raw)
The set fixes cb_access and xdp_adjust_head bits in struct bpf_prog,
that are used for requirement checks on the program rather than f.e.
heuristics. Thus, for tail calls, we cannot make any assumptions and
are forced to set them.
Thanks!
