Subject: [PATCH v3 bpf-next 0/2] bpf tcp save syn set/get sockoptions

From: "Nikita V. Shirokov" <[email-masked]>
Date: Thu, 30 Aug 2018 07:51:52 -0700

adding supprot for two new bpf's tcp sockopts:
TCP_SAVE_SYN (set) and TCP_SAVED_SYN (get)
this would allow for tcp-bpf program to build some logic based on fields from
ingress syn packet (e.g. doing tcp's tos/tclass reflection (see sample prog))
and do it transparently from userspace program point of view

v2->v3:
 - make patch series public
v1->v2:
 - adding proper SPDX license

Nikita V. Shirokov (2):
  new options for bpf_(set|get)sockopt
  new sample bpf prog
