File 0017-drbd-propagate-exposed-UUIDs-only-into-established-c.patch of Package drbd
From 0666bc5b014049b6aa184b5a8fdb60481b9c8717 Mon Sep 17 00:00:00 2001 From: Philipp Reisner <philipp.reisner@linbit.com> Date: Fri, 22 Sep 2023 15:09:07 +0200 Subject: [PATCH 17/20] drbd: propagate exposed UUIDs only into established connections Sending into connections in C_CONNECTING state while we exchange the feature and auth packets might interfere with exchanging those. I also witnessed that it might block unexpectedly long (2 - 6 seconds), holding the `connection->mutex[DATA_STREAM]` mutex and again causing troubles with establishing connections. This is a fix for commit 772e5b21d from April 2023 "drbd: Consider outdating a disk when more recent data is behind a diskless" Released with of 9.1.15 and 9.2.4. --- drbd/drbd_receiver.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drbd/drbd_receiver.c b/drbd/drbd_receiver.c index 0c3ab0fd486c..bfd265b86b43 100644 --- a/drbd/drbd_receiver.c +++ b/drbd/drbd_receiver.c @@ -7206,7 +7206,7 @@ static void propagate_exposed_uuid(struct drbd_device *device) u64 im; for_each_peer_device_ref(peer_device, im, device) { - if (peer_device->connection->cstate[NOW] < C_CONNECTING) + if (!test_bit(INITIAL_STATE_SENT, &peer_device->flags)) continue; drbd_send_current_uuid(peer_device, device->exposed_data_uuid, 0); } -- 2.35.3
