How is this related? Maybe add a comment to explain? Does
TCP_ESTABLISHED make sense for all types of sockets?
Hey Michael, definitely, I can leave a comment.
I agree, since I had the same doubt in previous versions, I think it's
worth putting a comment in the code to explain why.
Since there may be a v4, I'll leave some small comments in a separate
email.
Thanks,
Stefano
The real reason is due to this piece of logic in sockmap:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/net/core/sock_map.c?h=v6.2#n531
And because of it, you see the same thing in (for example)
unix_dgram_connect():
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/net/unix/af_unix.c?h=v6.2#n1394
I believe it makes sense for these other socket types.
