[PATCH openEuler-1.0-LTS] net: fix possible store tearing in neigh_periodic_work()
by Zhengchao Shao 08 Mar '24

08 Mar '24

From: Eric Dumazet <edumazet(a)google.com> mainline inclusion from mainline-v6.6-rc5 commit 25563b581ba3a1f263a00e8c9a97f5e7363be6fd category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I95AWK CVE: CVE-2023-52522 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- While looking at a related syzbot report involving neigh_periodic_work(), I found that I forgot to add an annotation when deleting an RCU protected item from a list. Readers use rcu_deference(*np), we need to use either rcu_assign_pointer() or WRITE_ONCE() on writer side to prevent store tearing. I use rcu_assign_pointer() to have lockdep support, this was the choice made in neigh_flush_dev().
