linux-toradex.git/include/linux/drbd.h, branch v2.6.35.4 Linux kernel for Apalis and Colibri modules drbd: Fixed a race between disk-attach and unexpected state changes 2010-06-14T10:19:41+00:00 Philipp Reisner philipp.reisner@linbit.com 2010-06-02T12:31:29+00:00 dc66c74de6f4238020db3e2041d4aca5c5b3e9bc This was a very hard to trigger race condition. If we got a state packet from the peer, after drbd_nl_disk() has already changed the disk state to D_NEGOTIATING but after_state_ch() was not yet run by the worker, then receive_state() might called drbd_sync_handshake(), which in turn crashed when accessing p_uuid.

This was a very hard to trigger race condition.

If we got a state packet from the peer, after drbd_nl_disk() has
already changed the disk state to D_NEGOTIATING but
after_state_ch() was not yet run by the worker, then receive_state()
might called drbd_sync_handshake(), which in turn crashed
when accessing p_uuid.
