commit: 6a58b8be556fb7de52ae0272a994a1c73fffc903 [2195/2195] vhost/vdpa: Add support to bind and attach iommufd
config: x86_64-randconfig-2002-20250501 (https://download.01.org/0day-ci/archive/20250627/202506270113.hqxVfK1W-lkp@…)
compiler: clang version 20.1.2 (https://github.com/llvm/llvm-project 58df0ef89dd64126512e4ee27b4ac3fd8ddf6247)
reproduce (this is a W=1 build): (https://download.01.org/0day-ci/archive/20250627/202506270113.hqxVfK1W-lkp@…)
If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags
| Reported-by: kernel test robot <lkp(a)intel.com>
| Closes: https://lore.kernel.org/oe-kbuild-all/202506270113.hqxVfK1W-lkp@intel.com/
Note: the openeuler/OLK-6.6 HEAD c02455c4cce8052f74fc11c09e9073c01c7f33a4 builds fine.
It only hurts bisectability.

[PATCH openEuler-1.0-LTS] PM: hibernate: defer device probing when resuming from hibernation
by Zeng Heng 26 Jun '25
by Zeng Heng 26 Jun '25

From: Tetsuo Handa <penguin-kernel(a)I-love.SAKURA.ne.jp>

from stable-v4.19.256
commit 5a283b59bce72c05c60e9f0fa92a28b5b850d8bb
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/IC5BR4
CVE: CVE-2022-50202
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------------------------------
syzbot is reporting hung task at misc_open() [1], for there is a race
window of AB-BA deadlock which involves probe_count variable. Currently
wait_for_device_probe() from snapshot_open() from misc_open() can sleep
forever with misc_mtx held if probe_count cannot become 0.
When a device is probed by hub_event() work function, probe_count is
incremented before the probe function starts, and probe_count is
decremented after the probe function completed.
There are three cases that can prevent probe_count from dropping to 0.
(a) A device being probed stopped responding (i.e. broken/malicious
hardware).
(b) A process emulating a USB device using /dev/raw-gadget interface
stopped responding for some reason.
(c) New device probe requests keeps coming in before existing device
probe requests complete.
The phenomenon syzbot is reporting is (b). A process which is holding
system_transition_mutex and misc_mtx is waiting for probe_count to become
0 inside wait_for_device_probe(), but the probe function which is called
from hub_event() work function is waiting for the processes which are
blocked at mutex_lock(&misc_mtx) to respond via /dev/raw-gadget interface.
This patch mitigates (b) by deferring wait_for_device_probe() from
snapshot_open() to snapshot_write() and snapshot_ioctl(). Please note that
the possibility of (b) remains as long as any thread which is emulating a
USB device via /dev/raw-gadget interface can be blocked by uninterruptible
blocking operations (e.g. mutex_lock()).
Please also note that (a) and (c) are not addressed. Regarding (c), we
should change the code to wait for only one device which contains the
image for resuming from hibernation. I don't know how to address (a), for
use of timeout for wait_for_device_probe() might result in loss of user
data in the image. Maybe we should require the userland to wait for the
image device before opening /dev/snapshot interface.

[PATCH OLK-5.10] fbdev: fbcon: Properly revert changes when vc_resize() failed
by Zeng Heng 26 Jun '25

commit a5a923038d70d2d4a86cb4e3f32625a5ee6e7e24
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9E448
CVE: CVE-2024-26798
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
-------------------------------------------------
fbcon_do_set_font() calls vc_resize() when font size is changed.
However, if if vc_resize() failed, current implementation doesn't
revert changes for font size, and this causes inconsistent state.
syzbot reported unable to handle page fault due to this issue [1].
syzbot's repro uses fault injection which cause failure for memory
allocation, so vc_resize() failed.
This patch fixes this issue by properly revert changes for font
related date when vc_resize() failed.

if (unlikely(vq->log_used))
QEMU disables vq->log_used
via VHOST_SET_VRING_ADDR.
mutex_lock(&vq->mutex);
vq->log_used = false now!
mutex_unlock(&vq->mutex);
QEMU gfree(vq->log_base)
log_used()
-> log_write(vq->log_base)
Assuming the VMM is QEMU. The vq->log_base is from QEMU userpace and can be
reclaimed via gfree(). As a result, this causes invalid memory writes to
QEMU userspace.
The control queue path has the same issue.

[Since this fix just want to protect vhost_add_used function from conccurent situation. And vhost_scsi_virtqueue
data structure is different so we cannot get the virt queue from vhost_work. In this version, get the virt queue
from cmd and solve the conccurent situation.]
