[bpf-next,v3,0/5] sockmap: add sockmap support for unix stream socket

Message

Jiang Wang . Aug. 2, 2021, 9:19 p.m. UTC

This patch series add support for unix stream type
for sockmap. Sockmap already supports TCP, UDP,
unix dgram types. The unix stream support is similar
to unix dgram.

Also add selftests for unix stream type in sockmap tests.


Jiang Wang (5):
  af_unix: add read_sock for stream socket types
  af_unix: add unix_stream_proto for sockmap
  selftest/bpf: add tests for sockmap with unix stream type.
  selftest/bpf: change udp to inet in some function names
  selftest/bpf: add new tests in sockmap for unix stream to tcp.

v1 -> v2 :
 - Call unhash in shutdown.
 - Clean up unix_create1 a bit.
 - Return -ENOTCONN if socket is not connected.

v2 -> v3 :
 - check for stream type in update_proto
 - remove intermediate variable in __unix_stream_recvmsg
 - fix compile warning in unix_stream_recvmsg
