[PATCH net v2 0/2] selftests/net: fixes for fin_ack_lat

From: Qingshuang Fu <[email protected]>

This series fixes two bugs in the fin_ack_lat self-test.

Patch 1 fixes the swapped kill() arguments in sig_handler(), so the
server actually forwards SIGTERM to the client.  It also makes the
wrapper script's cleanup tolerant of ESRCH, since the client may now
exit before the kill command reaches its PID.

Patch 2 adds a missing fork() error check: on failure the code falls
into server()'s infinite accept loop, producing empty output that the
wrapper script treats as a passing test.

Qingshuang Fu (2):
  selftests/net: fix kill() argument order and wrapper cleanup in fin_ack_lat
  selftests/net: check fork() return value in fin_ack_lat
