From 0b33a9164aca6332bf4a117af5528dea9675d782 Mon Sep 17 00:00:00 2001 From: Lars Ellenberg Date: Mon, 16 Nov 2009 15:58:04 +0100 Subject: add missing state change on corrupt packet header in drbd_recv_header Otherwise the 'state fixup' in the receiver will change to Unconnected, but the receiver will terminate itself, and any attempt at 'down'ing that drbd later will block forever. see also Bugz. #259 Signed-off-by: Philipp Reisner Signed-off-by: Lars Ellenberg --- drivers/block/drbd/drbd_receiver.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/drivers/block/drbd/drbd_receiver.c b/drivers/block/drbd/drbd_receiver.c index 9bbc509443e..fb29a75053e 100644 --- a/drivers/block/drbd/drbd_receiver.c +++ b/drivers/block/drbd/drbd_receiver.c @@ -3499,8 +3499,10 @@ static void drbdd(struct drbd_conf *mdev) while (get_t_state(&mdev->receiver) == Running) { drbd_thread_current_set_cpu(mdev); - if (!drbd_recv_header(mdev, header)) + if (!drbd_recv_header(mdev, header)) { + drbd_force_state(mdev, NS(conn, C_PROTOCOL_ERROR)); break; + } if (header->command < P_MAX_CMD) handler = drbd_cmd_handler[header->command]; -- cgit v1.2.3-70-g09d2
