Subject: [PATCH 5.9 011/152] btrfs: dont access possibly stale fs_info data for printing duplicate device
Date: Tue,  1 Dec 2020 09:52:06 +0100	[thread overview]
Message-ID: <20201201084713.329401921@linuxfoundation.org> (raw)
In-Reply-To: <20201201084711.707195422@linuxfoundation.org>

From: Johannes Thumshirn <johannes.thumshirn@wdc.com>

commit 0697d9a610998b8bdee6b2390836cb2391d8fd1a upstream.

Syzbot reported a possible use-after-free when printing a duplicate device
warning device_list_add().

At this point it can happen that a btrfs_device::fs_info is not correctly
setup yet, so we're accessing stale data, when printing the warning
message using the btrfs_printk() wrappers.

  ==================================================================

The syzkaller reproducer for this use-after-free crafts a filesystem image
and loop mounts it twice in a loop. The mount will fail as the crafted
image has an invalid chunk tree. When this happens btrfs_mount_root() will
call deactivate_locked_super(), which then cleans up fs_info and
fs_info::sb. If a second thread now adds the same block-device to the
filesystem, it will get detected as a duplicate device and
device_list_add() will reject the duplicate and print a warning. But as
the fs_info pointer passed in is non-NULL this will result in a
use-after-free.

Instead of printing possibly uninitialized or already freed memory in
btrfs_printk(), explicitly pass in a NULL fs_info so the printing of the
device name will be skipped altogether.

There was a slightly different approach discussed in
https://lore.kernel.org/linux-btrfs/20200114060920.4527-1-anand.jain@oracle.com/t/#u
