Subject: [PATCH] quota: Fix race between dqput() and dquot_scan_active()
Date: Fri, 10 Oct 2014 16:23:32 +0200 [thread overview]
Message-ID: <1412951028-4085-28-git-send-email-jack@suse.cz> (raw)
In-Reply-To: <1412951028-4085-1-git-send-email-jack@suse.cz>
Currently last dqput() can race with dquot_scan_active() causing it to
call callback for an already deactivated dquot. The race is as follows:
CPU1 CPU2
dqput()
spin_lock(&dq_list_lock);
if (atomic_read(&dquot->dq_count) > 1) {
- not taken
if (test_bit(DQ_ACTIVE_B, &dquot->dq_flags)) {
spin_unlock(&dq_list_lock);
->release_dquot(dquot);
if (atomic_read(&dquot->dq_count) > 1)
- not taken
dquot_scan_active()
spin_lock(&dq_list_lock);
if (!test_bit(DQ_ACTIVE_B, &dquot->dq_flags))
- not taken
atomic_inc(&dquot->dq_count);
spin_unlock(&dq_list_lock);
- proceeds to release dquot
ret = fn(dquot, priv);
- called for inactive dquot
Fix the problem by making sure possible ->release_dquot() is finished by
the time we call the callback and new calls to it will notice reference
dquot_scan_active() has taken and bail out.

This is the last patch needed to make ocfs2 quotas rock solid in my testing.
I will carry it in my tree and push it to Linus soon.
