[PATCH OLK-5.10] neighbour: fix data-races around n->output
by Wang Liang 24 Oct '24

24 Oct '24

From: Eric Dumazet <edumazet(a)google.com> mainline inclusion from mainline-v6.6-rc5 commit 5baa0433a15eadd729625004c37463acb982eca7 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAZ542 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- n->output field can be read locklessly, while a writer might change the pointer concurrently. Add missing annotations to prevent load-store tearing.
