Title:
bionic, xenial/hwe: misses "fuse: fix initial parallel dirops" patch
Status in linux package in Ubuntu:
Confirmed
Status in linux source package in Bionic:
Fix Released
Bug description:
SRU Justification:
[Impact]
* Enabling parallel dirops in fuse (FUSE_PARALLEL_DIROPS) may cause a
race condition that leave fuse inode's mutex held, triggering a
deadlock
* The problem is that the lock and unlock paths are relying on
get_fuse_conn(inode)->parallel_dirops to decide if the mutex needs to
be acquired/released, but its value might be set in the lock path and
unset in the unlock path (leaving the mutex held)
[Test Case]
* A test case that triggers the bug almost immediately can be found
here https://github.com/hanwen/go-fuse/pull/288
[Fix]
* Instead of relying on get_fuse_conn(inode)->parallel_dirops both in
fuse_lock_inode() and fuse_unlock_inode(), only check this flag in the
locking path and pass a variable to fuse_unlock_inode() to determine
if the mutex was acquired or not
[Regression Potential]
* Fix has been tested on the affected platform. It is an upstream fix
that seems to affect only 4.7+ kernels, more exactly in our case only
Bionic kernels (and derived) are affected. Cosmic and above already
include this fix. So regression potential is minimal.
[Original bug report]
Hello up there,
We were reported about a deadlock in the kernel while using a FUSE-based
filesystem on Ubuntu.
The kernel in question is Ubuntu-hwe-4.15.0-47.50~16.04.1 from Xenial/HWE. We
tracked this bug to the fact that 4.15.x kernel in Ubuntu does not include the
following patch, in despite the patch being marked as needed for v4.7+ stable
kernels:
https://git.kernel.org/linus/63576c13bd
Please see the following go-fuse issue for full details:
https://github.com/hanwen/go-fuse/issues/281#issuecomment-480008562
The bug is potentially applicable to libfuse users too since libfuse
by default enables parallel dirops whenever kernel claims support for
it, which libfuse maintained confirmed:
https://github.com/hanwen/go-fuse/issues/281#issuecomment-480013202
https://github.com/hanwen/go-fuse/issues/281#issuecomment-480510381
We tested that cherry-picking 63576c13bd into 4.15.x series makes the
problem go away:
https://github.com/hanwen/go-fuse/issues/281#issuecomment-480499969
So please include https://git.kernel.org/linus/63576c13bd into Ubuntu
4.15.x kernel series which are bionic/master and xenial/hwe, and which
currently don't have this patch.
--------
Here is a full list of FUSE patches marked to be needed in stable
kernels starting from v4.15:
kirr@deco:~/src/linux/linux$ git log --oneline v4.15..v5.1-rc3
--grep="stable@" -- fs/fuse/
a2ebba824106 fuse: decrement NR_WRITEBACK_TEMP on the right page

2d84a2d19b61 fuse: fix possibly missed wake-up after abort
7fabaf303458 fuse: fix leaked notify reply
908a572b80f6 fuse: fix blocked_waitq wakeup
4c316f2f3ff3 fuse: set FR_SENT while locked
d2d2d4fb1f54 fuse: Fix use-after-free in fuse_dev_do_write()
bc78abbd55dd fuse: Fix use-after-free in fuse_dev_do_read()
a2477b0e67c5 fuse: Don't access pipe->buffers without pipe_lock()
63576c13bd17 fuse: fix initial parallel dirops
e8f3bd773d22 fuse: Fix oops at process_init_reply()
b8f95e5d13f5 fuse: umount should wait for all requests
45ff350bbd9d fuse: fix unlocked access to processing queue
87114373ea50 fuse: fix double request_end()
543b8f8662fe (tag: fuse-update-4.18) fuse: don't keep dead fuse_conn at
fuse_fill_super().
6becdb601bae fuse: fix control dir setup and teardown
8a301eb16d99 fuse: fix congested state leak on aborted connections
df0e91d48827 fuse: atomic_o_trunc should truncate pagecache
Among those only 8a3177db59cd and 2d84a2d19b61 should not be applied
to 4.15.x becuase they cure a problem introduced in a later kernel
(please see got log without --oneline for stable@ details)
However both bionic and xenial/hwe has much less fuse patches applied:
kirr@deco:~/src/linux/linux$ git log --oneline v4.15..bionic/master --
fs/fuse/
e992e3521885 fuse: fix control dir setup and teardown
f3a3e0537dcd fuse: don't keep dead fuse_conn at fuse_fill_super().
840c77082f93 fuse: atomic_o_trunc should truncate pagecache
c0e31b214498 fuse: fix congested state leak on aborted connections
45f23c59120f UBUNTU: SAUCE: (namespace) fuse: Allow user namespace mounts
1223588451c6 UBUNTU: SAUCE: (namespace) fuse: Restrict allow_other to the
superblock's namespace or a descendant
b4d1889491a0 UBUNTU: SAUCE: (namespace) fuse: Support fuse filesystems
outside of init_user_ns
kirr@deco:~/src/linux/linux$ git log --oneline v4.15..xenial/hwe -- fs/fuse/
e992e3521885 fuse: fix control dir setup and teardown
f3a3e0537dcd fuse: don't keep dead fuse_conn at fuse_fill_super().
840c77082f93 fuse: atomic_o_trunc should truncate pagecache
c0e31b214498 fuse: fix congested state leak on aborted connections
45f23c59120f UBUNTU: SAUCE: (namespace) fuse: Allow user namespace mounts
1223588451c6 UBUNTU: SAUCE: (namespace) fuse: Restrict allow_other to the
superblock's namespace or a descendant
b4d1889491a0 UBUNTU: SAUCE: (namespace) fuse: Support fuse filesystems
outside of init_user_ns
which suggests that other FUSE fixes should be cherry-picked too.
Please consider cherry-picking those additional patches too. They are all in
upstream kernel
stable series, e.g. stable/linux-4.14.y has them:
kirr@deco:~/src/linux/linux$ git log --oneline v4.14..stable/linux-4.14.y --
fs/fuse/
266a69895b89 fuse: handle zero sized retrieve correctly
b928e93d864c fuse: decrement NR_WRITEBACK_TEMP on the right page
65f222bb370e fuse: call pipe_buf_release() under pipe lock
c1149b873482 fuse: continue to send FUSE_RELEASEDIR when FUSE_OPEN returns
ENOSYS
6ceec07cc84a fuse: fix leaked notify reply
a42d933dc281 fuse: fix use-after-free in fuse_direct_IO()
78da72ee42d8 fuse: set FR_SENT while locked
f6f21a2b70c6 fuse: fix blocked_waitq wakeup
ab962e91008a fuse: Fix use-after-free in fuse_dev_do_write()
d94b3a2375cb fuse: Fix use-after-free in fuse_dev_do_read()
e8a3f3a03655 fuse: Add missed unlock_page() to fuse_readpages_fill()
ff4a71855d0a fuse: Fix oops at process_init_reply()
973206923812 fuse: umount should wait for all requests
fc17d7519e8e fuse: fix unlocked access to processing queue
cfb6eca6e4bb fuse: fix double request_end()
7d392674443c fuse: fix initial parallel dirops
eaebcf902ae0 fuse: Don't access pipe->buffers without pipe_lock()
69829f749a43 fuse: fix control dir setup and teardown
3a37d85a90da fuse: don't keep dead fuse_conn at fuse_fill_super().
2f7bf369b5f8 fuse: atomic_o_trunc should truncate pagecache
02832578eb9d fuse: fix congested state leak on aborted connections
and it is just that stable/linux-4.15.y stopped being maintained by
Greg KH.
