It was brought to me (~inaddy) the following situation with multipathd:

44 lock(wp
vecs
lock);
(gdb) print wp
vecs
lock
$1 = {mutex = 0x168c280, depth = 1}
In pthread_mutex_lock.c:62 there's an assert that fails:
#4 0x7fbc6b849efb in __pthread_mutex_lock (mutex=0xfefefefefefefeff) at
pthread_mutex_lock.c:62
62 assert (mutex_
data._owner == 0);
In this run:
(gdb) p *wp
vecs
lock
mutex
$3 = {_data = {lock = 1, __count = 0, __owner = 49, __nusers = 0, __kind = 0,
__spins = 0, __list = {_prev = 0x0, __next = 0x}},
__size = \001\000\000\000\000\000\000\000\061, '\000' repeats 23
times\377, \377\377\377\000\000\000, __align = 1}
so __owner is 49 and not 0.
Note that 49 is somewhat strange; it's expected to be a pid_t obtained via
pid_t id = THREAD_GETMEM (THREAD_SELF, tid);
According to https://bugzilla.redhat.com/show_bug.cgi?id=570278 , this
assert failure could be an expected behaviour if, for some reason the
multipath code was trying to release a mutex that has already been
freed.
The multipath-tools package is up to date (0.4.9-3ubuntu5)
I do not find obvious thing related in
http://git.opensvc.com/gitweb.cgi?p=multipath-tools%2F.git except may be

#
In between Precise's version and Upstream there are the following
patches touching waiter.c:
d887f4a = signal waiter thread to stop waiting on dm events
5ee9f71 = simplify multipath signal handlers
af4fd6d = Fix race condition in stop_waiter_thread()
e1fcc59 = multipath: clean up code for stopping the waiter threads
03ec4ef = multipath: fix shutdown crashes
4dfdaf2 = multipath: Update multipath device on show topology
c301a3f = Race condition when calling stop_waiter_thread()
96f8146 = libmultipath: update waiter handling
This specific one: 96f8146 (libmultipath: update waiter handling)
The current 'waiter' structure accesses fields which belong
to the main 'mpp' structure, which has a totally different
lifetime.
Shows that due to different lifetime between different structures, there
can be use-after-free segfaults (what seems to be happening).
waiter.c:44 = lock(wp-vecs-lock);

In this run:
(gdb) p *wp
vecs
lock
mutex
$3 = {_data = {lock = 1, __count = 0, __owner = 49, __nusers = 0, __kind = 0,
__spins = 0, __list = {_prev = 0x0, __next = 0x}},
__size = \001\000\000\000\000\000\000\000\061, '\000' repeats 23
times\377, \377\377\377\000\000\000, __align = 1}
so __owner is 49 and not 0.
Note that 49 is somewhat strange; it's expected to be a pid_t obtained via
pid_t id = THREAD_GETMEM (THREAD_SELF, tid);
According to https://bugzilla.redhat.com/show_bug.cgi?id=570278 , this
assert failure could be an expected behaviour if, for some reason the
multipath code was trying to release a mutex that has already been
freed.

This specific one: 96f8146 (libmultipath: update waiter handling)
The current 'waiter' structure accesses fields which belong
to the main 'mpp' structure, which has a totally different
lifetime.
Shows that due to different lifetime between different structures, there
can be use-after-free segfaults (what seems to be happening).

[Bug 1354114] Re: multipath segmentation Fault (libmultipath: update waiter handling)
Attaching SRU proposal. Description: [PATCH] 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.

[Bug 1354114] Re: multipath segmentation Fault (libmultipath: update waiter handling)
So probably to last commits touching libmultipath/waiter.c (and fixing this issue) would be: 1) commit e1fcc5933ac44683cdee1a02304e1115abec3ff5 Author: Benjamin Marzinski bmarz...@redhat.com Date: Sat May 19 01:37:03 2012 -0500 multipath: clean up code for stopping the waiter threads The way multipathd currently stops the waiter threads needs some work. Right now they are stopped by being sent the SIGUSR1 signal. However their cleanup code assumes that they are being cancelled, just like all the other threads are. There's no reason for them to be so unnecessarily complicated and different from the other threads This patch does a couple of things. First, it removes the mutex from the event_thread. This wasn't doing anything. It was designed to protect the wp-mapname variable, which the waiter threads were checking to see if they should quit. However, the mutex was only ever being used by the thread itself, and it clearly didn't need to serialize with itself. Also, the function to clear the mapname, signal_waiter(), was set with pthread_cleanup_push(), which never got called early, since the threads weren't being cancelled. Thus, the mapname never got cleared until the pthreads were about to shut down. The patch also rips out all the signal stopping code, and just uses pthread_cancel. There already are cancellation points in the waiter thread code. Between the cancellation points, both explicit and implicit, and the fact that the waiter threads will never be killed except when the killer is holding the vecs lock, there shouldn't be any place where the waiter thread can access freed data. To make sure the waiter thread cleans itself up properly, the dmt has been moved into the event_thread structure, and is destroyed in free_waiter() if necessary.

In pthread_mutex_lock.c:62 there's an assert that fails:

so __owner is 49 and not 0.
Note that 49 is somewhat strange; it's expected to be a pid_t obtained via
pid_t id = THREAD_GETMEM (THREAD_SELF, tid);
According to https://bugzilla.redhat.com/show_bug.cgi?id=570278 , this
assert failure could be an expected behaviour if, for some reason the
multipath code was trying to release a mutex that has already been
freed.

This specific one: 96f8146 (libmultipath: update waiter handling)
The current 'waiter' structure accesses fields which belong
to the main 'mpp' structure, which has a totally different
lifetime.
Shows that due to different lifetime between different structures, there
can be use-after-free segfaults (what seems to be happening).

[Bug 1354114] Re: multipath segmentation Fault (libmultipath: update waiter handling)
Attaching SRU proposal. Description: [PATCH] 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.

And maybe this also: Maybe this: commit 03ec4efe8775f0ca076df3fb85b9defab4ffad30 Author: Benjamin Marzinski bmarz...@redhat.com Date: Fri Feb 10 12:10:11 2012 -0600 multipath: fix shutdown crashes A number of processes don't reach a pthread cancellation point before they use the pathvec or mpvec vectors, after they've locked the vecs lock. This can cause crashes on shutdown, since these vectors are deallocated. Also, the log thread accesses a number of resources which may have been deallocated during shutdown without holding any locks. This patch avoids these issues by adding pthread_testcancel() checks after acquiring the vecs lock, and having the child process make sure the log thread has exitted before deallocating the resources.

[Bug 1354114] Re: multipath segmentation Fault (libmultipath: update waiter handling)
So probably to last commits touching libmultipath/waiter.c (and fixing this issue) would be: 1) commit e1fcc5933ac44683cdee1a02304e1115abec3ff5 Author: Benjamin Marzinski bmarz...@redhat.com Date: Sat May 19 01:37:03 2012 -0500 multipath: clean up code for stopping the waiter threads The way multipathd currently stops the waiter threads needs some work. Right now they are stopped by being sent the SIGUSR1 signal. However their cleanup code assumes that they are being cancelled, just like all the other threads are. There's no reason for them to be so unnecessarily complicated and different from the other threads This patch does a couple of things. First, it removes the mutex from the event_thread. This wasn't doing anything. It was designed to protect the wp-mapname variable, which the waiter threads were checking to see if they should quit. However, the mutex was only ever being used by the thread itself, and it clearly didn't need to serialize with itself. Also, the function to clear the mapname, signal_waiter(), was set with pthread_cleanup_push(), which never got called early, since the threads weren't being cancelled. Thus, the mapname never got cleared until the pthreads were about to shut down. The patch also rips out all the signal stopping code, and just uses pthread_cancel. There already are cancellation points in the waiter thread code. Between the cancellation points, both explicit and implicit, and the fact that the waiter threads will never be killed except when the killer is holding the vecs lock, there shouldn't be any place where the waiter thread can access freed data. To make sure the waiter thread cleans itself up properly, the dmt has been moved into the event_thread structure, and is destroyed in free_waiter() if necessary.

(gdb) print wp

lock
$1 = {mutex = 0x168c280, depth = 1}
In pthread_mutex_lock.c:62 there's an assert that fails:
#4 0x7fbc6b849efb in __pthread_mutex_lock (mutex=0xfefefefefefefeff) at
pthread_mutex_lock.c:62
62 assert (mutex_
data._owner == 0);
In this run:
(gdb) p *wp
vecs
lock
mutex
$3 = {_data = {lock = 1, __count = 0, __owner = 49, __nusers = 0, __kind = 0,
__spins = 0, __list = {_prev = 0x0, __next = 0x}},
__size = \001\000\000\000\000\000\000\000\061, '\000' repeats 23
times\377, \377\377\377\000\000\000, __align = 1}
so __owner is 49 and not 0.
Note that 49 is somewhat strange; it's expected to be a pid_t obtained via
pid_t id = THREAD_GETMEM (THREAD_SELF, tid);
According to https://bugzilla.redhat.com/show_bug.cgi?id=570278 , this
assert failure could be an expected behaviour if, for some reason the
multipath code was trying to release a mutex that has already been
freed.
The multipath-tools package is up to date (0.4.9-3ubuntu5)
I do not find obvious thing related in
http://git.opensvc.com/gitweb.cgi?p=multipath-tools%2F.git except may be
http://git.opensvc.com/gitweb.cgi?p=multipath-tools/.git;a=commitdiff;h=5ee9f716549d913aeb9800041f78ee9c6a50d860

In between Precise's version and Upstream there are the following
patches touching waiter.c:
d887f4a = signal waiter thread to stop waiting on dm events
5ee9f71 = simplify multipath signal handlers
af4fd6d = Fix race condition in stop_waiter_thread()
e1fcc59 = multipath: clean up code for stopping the waiter threads
03ec4ef = multipath: fix shutdown crashes
4dfdaf2 = multipath: Update multipath device on show topology
c301a3f = Race condition when calling stop_waiter_thread()
96f8146 = libmultipath: update waiter handling
This specific one: 96f8146 (libmultipath: update waiter handling)
The current 'waiter' structure accesses fields which belong
to the main 'mpp' structure, which has a totally different
lifetime.
Shows that due to different lifetime between different structures, there
can be use-after-free segfaults (what seems to be happening).
waiter.c:44 = lock(wp-vecs-lock);
