[PATCH OLK-6.6] tcp: Fix use-after-free of nreq in reqsk_timer_handler().

From: Kuniyuki Iwashima <kuniyu(a)amazon.com> stable inclusion from stable-v6.6.64 commit 65ed89cad1f57034c256b016e89e8c0a4ec7c65b category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBA6RL CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… ------------------------------------------------- [ Upstream commit c31e72d021db2714df03df6c42855a1db592716c ] The cited commit replaced inet_csk_reqsk_queue_drop_and_put() with __inet_csk_reqsk_queue_drop() and reqsk_put() in reqsk_timer_handler(). Then, oreq should be passed to reqsk_put() instead of req; otherwise use-after-free of nreq could happen when reqsk is migrated but the retry attempt failed (e.g. due to timeout). Let's pass oreq to reqsk_put(). Fixes: e8c526f2bdf1 ("tcp/dccp: Don't use timer_pending() in reqsk_queue_unlink().")
