It looks like the fix above introduces regressions (actually other new bugs):
commit 96f81469ff993b6063bb8829d9b336590510466d Author: Hannes Reinecke <h...@suse.de> Date: Mon May 4 16:46:58 2009 +0200 libmultipath: update waiter handling The current 'waiter' structure accesses fields which belong to the main 'mpp' structure, which has a totally different lifetime. With this patch most of these dependencies are removed and the 'waiter' structure can run independently of the main 'mpp' structure, reducing the risk of use-after-free faults. Signed-off-by: Hannes Reinecke <h...@suse.de> Introduces this problem: commit c301a3f09203edf91df5a9adf4e32ea2a7238cda Author: Hannes Reinecke <h...@suse.de> Date: Wed May 25 14:40:19 2011 +0200 Race condition when calling stop_waiter_thread() We cannot access the waiter structure from other threads as the lifetime is totally different and it might be deleted at any time. So we better store the pthread id in the calling thread and just send a signal to the thread.
