Eric Dumazet 6c36b5c244 net: tipc: remove one synchronize_net() from tipc_nametbl_stop() ... tipc_exit_net() is very slow and is abused by syzbot. tipc_nametbl_stop() is called for each netns being dismantled. Calling synchronize_net() right before freeing tn->nametbl is a big hammer. Replace this with kfree_rcu(). Note that RCU is not properly used here, otherwise tn->nametbl should be cleared before the synchronize_net() or kfree_rcu(), or even before the cleanup loop. We might need to fix this at some point. Also note tipc uses other synchronize_rcu() calls, more work is needed to make tipc_exit_net() much faster. List of remaining calls to synchronize_rcu() tipc_detach_loopback() (dev_remove_pack()) tipc_bcast_stop() tipc_sk_rht_destroy() Signed-off-by: Eric Dumazet <edumazet@google.com> Link: https://patch.msgid.link/20241204210234.319484-1-edumazet@google.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>		2024-12-06 17:41:28 -08:00
