Subject: [PATCHSET 0/2] Fix SO_INQ for af_unix
Date: Thu, 18 Dec 2025 07:59:12 -0700 [thread overview]
Message-ID: <20251218150114.250048-1-axboe@kernel.dk> (raw)
Hi,
We ran into an issue with the recently added SO_INQ support for
unix/stream sockets. First patch fixes the unconditional posting of
cmsg for io_uring cases, which it should not do, and the second patch
fixes the condition for when to post an SO_INQ cmsg in general (which
is only for the non-error case).
Please review and apply if you're happy with them, these patches fix
a regression introduced in 6.17 and newer kernels and hence are marked
for stable as well.
