  "message": "af_unix: don\u0027t post cmsg for SO_INQ unless explicitly asked for\n\ncommit 4d1442979e4a53b9457ce1e373e187e1511ff688 upstream.\n\nA previous commit added SO_INQ support for AF_UNIX (SOCK_STREAM), but it\nposts a SCM_INQ cmsg even if just msg-\u003emsg_get_inq is set. This is\nincorrect, as -\u003emsg_get_inq is just the caller asking for the remainder\nto be passed back in msg-\u003emsg_inq, it has nothing to do with cmsg. The\noriginal commit states that this is done to make sockets\nio_uring-friendly\", but it\u0027s actually incorrect as io_uring doesn\u0027t use\ncmsg headers internally at all, and it\u0027s actively wrong as this means\nthat cmsg\u0027s are always posted if someone does recvmsg via io_uring.\n\nFix that up by only posting a cmsg if u-\u003erecvmsg_inq is set.\n\nAdditionally, mirror how TCP handles inquiry handling in that it should\nonly be done for a successful return. This makes the logic for the two\nidentical.\n\nCc: stable@vger.kernel.org\nFixes: df30285b3670 (\"af_unix: Introduce SO_INQ.\")\nReported-by: Julian Orth \u003cju.orth@gmail.com\u003e\nLink: https://github.com/axboe/liburing/issues/1509\nSigned-off-by: Jens Axboe \u003caxboe@kernel.dk\u003e\nReviewed-by: Willem de Bruijn \u003cwillemb@google.com\u003e\nLink: https://patch.msgid.link/07adc0c2-2c3b-4d08-8af1-1c466a40b6a8@kernel.dk\nSigned-off-by: Paolo Abeni \u003cpabeni@redhat.com\u003e\n",
