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
v3 -> v4 : - remove sk_is_unix_stream, just check TCP_ESTABLISHED for UNIX sockets. - add READ_ONCE in unix_dgram_recvmsg - remove type check in unix_stream_bpf_update_proto
v4 -> v5 : - add two missing READ_ONCE for sk_prot.
To support sockmap for af_unix stream type, implement read_sock, which is similar to the read_sock for unix dgram sockets.

Previously, sockmap for AF_UNIX protocol only supports dgram type. This patch add unix stream type support, which is similar to unix_dgram_proto. To support sockmap, dgram and stream cannot share the same unix_proto anymore, because they have different implementations, such as unhash for stream type (which will remove closed or disconnected sockets from the map), so rename unix_proto to unix_dgram_proto and add a new unix_stream_proto.
Also implement stream related sockmap functions. And add dgram key words to those dgram specific functions.
