* drbd: fix print_st_err()'s prototype to match the definitionLuc Van Oostenryck2019-12-05
| | | | | | | | | | | | | | | [ Upstream commit 2c38f035117331eb78d0504843c79ea7c7fabf37 ] print_st_err() is defined with its 4th argument taking an 'enum drbd_state_rv' but its prototype use an int for it. Fix this by using 'enum drbd_state_rv' in the prototype too.

* drbd: fix race between role change and handshakePhilipp Reisner2014-11-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Symptoms: If DRBD was "cleanly shut down" (all in sync, both Secondary before disconnect, identical data generation uuids), and then one side was promoted *during* the next connection handshake, the role change could confuse the handshake. The Primary would get stuck in WFBitmapS, the Secondary would log unexpected cstate (Connected) in receive_bitmap and get stuck in WFBitmapT. Fix: The test in is_valid_soft_transition wrong. It works because the not allowed actions (promote/attach) do not touch the cstate. The previous condition failed to demand a cstate change in one clause. In order to avoid deadlocks give up the state_mutex while waiting for the transient state to go away.
