Incorrect arguments are passed to fcntl() in test_sockmap.c when invoking it to set file status flags. If O_NONBLOCK is used as 2nd argument and passed into fcntl, -EINVAL will be returned (See do_fcntl() in fs/fcntl.c). The correct approach is to use F_SETFL as 2nd argument, and O_NONBLOCK as 3rd one.

Good catch. But we also need to figure out why some tests failing with this patch applied and fix them in one go:
# 6/ 7 sockmap::txmsg test skb:FAIL #21/ 7 sockhash::txmsg test skb:FAIL #36/ 7 sockhash:ktls:txmsg test skb:FAIL Pass: 42 Fail: 3
Sorry, I didn't notice these fails in my testing before, they do exist. I'll try to fix them and sent a v2 soon.
Not 100% sure but a hint. I would look into where the stream parser is waking up the sock here. I'm not sure there is an easy fix tbh. I can help look at this soon as well if you don't beat me to a fix.
Thanks for looking into it.
Thanks, -Geliang
