Subject: [PATCH 5.14 115/168] loop: reduce the loop_ctl_mutex scope
Date: Mon, 20 Sep 2021 18:44:13 +0200 [thread overview]
Message-ID: <20210920163925.417328067@linuxfoundation.org> (raw)
In-Reply-To: <20210920163921.633181900@linuxfoundation.org>
From: Tetsuo Handa <penguin-kernel@i-love.sakura.ne.jp>
[ Upstream commit 1c500ad706383f1a6609e63d0b5d1723fd84dab9 ]
syzbot is reporting circular locking problem at __loop_clr_fd() [1], for
commit a160c6159d4a0cf8 ("block: add an optional probe callback to
major_names") is calling the module's probe function with major_names_lock
held.
Fortunately, since commit 990e78116d38059c ("block: loop: fix deadlock
between open and remove") stopped holding loop_ctl_mutex in lo_open(),
current role of loop_ctl_mutex is to serialize access to loop_index_idr
and loop_add()/loop_remove(); in other words, management of id for IDR.
To avoid holding loop_ctl_mutex during whole add/remove operation, use
a bool flag to indicate whether the loop device is ready for use.
loop_unregister_transfer() which is called from cleanup_cryptoloop()
currently has possibility of use-after-free problem due to lack of
serialization between kfree() from loop_remove() from loop_control_remove()
and mutex_lock() from unregister_transfer_cb(). But since lo->lo_encryption
should be already NULL when this function is called due to module unload,
and commit 222013f9ac30b9ce ("cryptoloop: add a deprecation warning")
indicates that we will remove this function shortly, this patch updates
this function to emit warning instead of checking lo->lo_encryption.
Holding loop_ctl_mutex in loop_exit() is pointless, for all users must
close /dev/loop-control and /dev/loop$num (in order to drop module's
refcount to 0) before loop_exit() starts, and nobody can open
/dev/loop-control or /dev/loop$num afterwards.
