13 years agoFix a deadlock in clvmd.
Petr Rockai [Wed, 20 Oct 2010 14:46:45 +0000 (14:46 +0000)]
Fix a deadlock in clvmd.

The signalling code (pthread_cond_signal/pthread_cond_wait) in the
pre_and_post_thread was using the wait mutex (see man pthread_cond_wait)
incorrectly, and this could cause clvmd to deadlock when timing was
right. Detailed explanation of the problem follows.

There is a single mutex around (L for Lock, U for Unlock), a signal (S) and a
wait (W). C for pthread_create. Time flows from left to right, each arrow is a
thread.

So first the "naive" scenario, with no mutex (PPT = pre_and_post_thread, MCT =
main clvmd thread; well actually the thread that does read_from_local_sock). I
will also use X, for a moment when MCT actually waits for something to happen
that PPT was supposed to do.

MCT -----C ------S--X-----S----X----------------------S------XXXXXXXXX
         |                everything OK up to this --> <-- point...
PPT       -----WWW-----WWWW------------------------------WWWWWWWWWWWWW

Ok, so pthread API actually does not let you use W/S like that. It goes out of
its way to tell you that you need a mutex to protect the W so that the above
cannot happen. *But* if you are creative and just lock around the W's and S's,
this happens:

MCT ----C-----LSU----X-----LSU----X------------LSU------XXXXXXX
        |
PPT      ---LWWWU-------LWWWWU-----------------------LWWWWWWWWW

Ooops. Nothing changed (the above is what actually was done by clvmd before
this satch). So let's do it differently, holding L locked *all* the time in
PPT, unless we are actually in W (this is something that the pthread API does
itself, see the man page).

MCT ----C-----LSU------X---LSU---X-----LLLLLLLSU----X----
        |                             (and they live happily ever after)
PPT     L---WWWWW---------WWWW----------------W----------

So W actually ensures that L is unlocked *atomically* together with entering
the wait. That means that unless PPT is actually waiting, it cannot be
signalled by MCT. So if MCT happens to signal it too soon (it wasn't waiting
yet), it (MCT) will be blocked on the mutex (L), until PPT is actually ready to
do something.

Fix for bug 637936: killing both redundant logs causes deadlock

Problem:
When both legs of a mirrored log fail, neither the log nor the parent
mirror can proceed.  The repair code must be careful to replace the
log with an error target before operating on the parent - otherwise,
the parent can get stuck trying to suspend because it can't push through
any writes.  The steps to replace the log device with an error target
were incomplete and resulted in the replacement not happening at all!

The code originally had all the necessary logic to complete the
replacement task, but was pulled out in a effort to clean-up that
section of code, while fixing another bug:
<offending commit msg>
In addition, I added following three changes.

- Removed tmp_orphan_lvs handling procedure
  It seems that _delete_lv() can handle detached_log_lv properly
  without adding mirror legs in mirrored log to tmp_orphan_lvs.
  Therefore, I removed the procedure.

- Removed vg_write()/vg_commit()
  Metadata is saved by vg_write()/vg_commit() just after detached_log_lv
  is handled. Therefore, I removed vg_write()/vg_commit().
