From c274af2242693f59f00851b3660a21b10bcd76cc Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Wed, 16 Aug 2023 08:15:33 +0000 Subject: inet: introduce inet->inet_flags Various inet fields are currently racy. do_ip_setsockopt() and do_ip_getsockopt() are mostly holding the socket lock, but some (fast) paths do not. Use a new inet->inet_flags to hold atomic bits in the series. Remove inet->cmsg_flags, and use instead 9 bits from inet_flags.
