| In the Linux kernel, the following vulnerability has been resolved:
af_unix: Fix task hung while purging oob_skb in GC.
syzbot reported a task hung; at the same time, GC was looping infinitely
in list_for_each_entry_safe() for OOB skb. [0]
syzbot demonstrated that the list_for_each_entry_safe() was not actually
safe in this case.
A single skb could have references for multiple sockets. If we free such
a skb in the list_for_each_entry_safe(), the current and next sockets could
be unlinked in a single iteration.
unix_notinflight() uses list_del_init() to unlink the socket, so the
prefetched next socket forms a loop itself and list_for_each_entry_safe()
never stops.
Here, we must use while() and make sure we always fetch the first socket.

| In the Linux kernel, the following vulnerability has been resolved:
cxl/pci: Fix disabling memory if DVSEC CXL Range does not match a CFMWS window
The Linux CXL subsystem is built on the assumption that HPA == SPA.
That is, the host physical address (HPA) the HDM decoder registers are
programmed with are system physical addresses (SPA).
During HDM decoder setup, the DVSEC CXL range registers (cxl-3.1,
8.1.3.8) are checked if the memory is enabled and the CXL range is in
a HPA window that is described in a CFMWS structure of the CXL host
bridge (cxl-3.1, 9.18.1.3).
Now, if the HPA is not an SPA, the CXL range does not match a CFMWS
window and the CXL memory range will be disabled then. The HDM decoder
stops working which causes system memory being disabled and further a
system hang during HDM decoder initialization, typically when a CXL
enabled kernel boots.
Prevent a system hang and do not disable the HDM decoder if the
decoder's CXL range is not found in a CFMWS window.
Note the change only fixes a hardware hang, but does not implement
HPA/SPA translation. Support for this can be added in a follow on
patch series. |
| In the Linux kernel, the following vulnerability has been resolved:
md: Don't ignore suspended array in md_check_recovery()
mddev_suspend() never stop sync_thread, hence it doesn't make sense to
ignore suspended array in md_check_recovery(), which might cause
sync_thread can't be unregistered.
After commit f52f5c71f3d4 ("md: fix stopping sync thread"), following
hang can be triggered by test shell/integrity-caching.sh:
1) suspend the array:
raid_postsuspend
mddev_suspend
2) stop the array:
raid_dtr
md_stop
__md_stop_writes
stop_sync_thread
set_bit(MD_RECOVERY_INTR, &mddev->recovery);
md_wakeup_thread_directly(mddev->sync_thread);
wait_event(..., !test_bit(MD_RECOVERY_RUNNING, &mddev->recovery))
3) sync thread done:
md_do_sync
set_bit(MD_RECOVERY_DONE, &mddev->recovery);
md_wakeup_thread(mddev->thread);
4) daemon thread can't unregister sync thread:
md_check_recovery
if (mddev->suspended)
return; -> return directly
md_read_sync_thread
clear_bit(MD_RECOVERY_RUNNING, &mddev->recovery);
-> MD_RECOVERY_RUNNING can't be cleared, hence step 2 hang;
This problem is not just related to dm-raid, fix it by ignoring
suspended array in md_check_recovery(). And follow up patches will
improve dm-raid better to frozen sync thread during suspend. |
| In the Linux kernel, the following vulnerability has been resolved:
md: Don't ignore read-only array in md_check_recovery()
Usually if the array is not read-write, md_check_recovery() won't
register new sync_thread in the first place. And if the array is
read-write and sync_thread is registered, md_set_readonly() will
unregister sync_thread before setting the array read-only. md/raid
follow this behavior hence there is no problem.
After commit f52f5c71f3d4 ("md: fix stopping sync thread"), following
hang can be triggered by test shell/integrity-caching.sh:
1) array is read-only. dm-raid update super block:
rs_update_sbs
ro = mddev->ro
mddev->ro = 0
-> set array read-write
md_update_sb
2) register new sync thread concurrently.
3) dm-raid set array back to read-only:
rs_update_sbs
mddev->ro = ro
4) stop the array:
raid_dtr
md_stop
stop_sync_thread
set_bit(MD_RECOVERY_INTR, &mddev->recovery);
md_wakeup_thread_directly(mddev->sync_thread);
wait_event(..., !test_bit(MD_RECOVERY_RUNNING, &mddev->recovery))
5) sync thread done:
md_do_sync
set_bit(MD_RECOVERY_DONE, &mddev->recovery);
md_wakeup_thread(mddev->thread);
6) daemon thread can't unregister sync thread:
md_check_recovery
if (!md_is_rdwr(mddev) &&
!test_bit(MD_RECOVERY_NEEDED, &mddev->recovery))
return;
-> -> MD_RECOVERY_RUNNING can't be cleared, hence step 4 hang;
The root cause is that dm-raid manipulate 'mddev->ro' by itself,
however, dm-raid really should stop sync thread before setting the
array read-only. Unfortunately, I need to read more code before I
can refacter the handler of 'mddev->ro' in dm-raid, hence let's fix
the problem the easy way for now to prevent dm-raid regression. |
| In the Linux kernel, the following vulnerability has been resolved:
md: Don't register sync_thread for reshape directly
Currently, if reshape is interrupted, then reassemble the array will
register sync_thread directly from pers->run(), in this case
'MD_RECOVERY_RUNNING' is set directly, however, there is no guarantee
that md_do_sync() will be executed, hence stop_sync_thread() will hang
because 'MD_RECOVERY_RUNNING' can't be cleared.
Last patch make sure that md_do_sync() will set MD_RECOVERY_DONE,
however, following hang can still be triggered by dm-raid test
shell/lvconvert-raid-reshape.sh occasionally:

Fix this problem by remove the code to register sync_thread directly
from raid10 and raid5. And let md_check_recovery() to register
sync_thread. |
| In the Linux kernel, the following vulnerability has been resolved:
md: Don't suspend the array for interrupted reshape
md_start_sync() will suspend the array if there are spares that can be
added or removed from conf, however, if reshape is still in progress,
this won't happen at all or data will be corrupted(remove_and_add_spares
won't be called from md_choose_sync_action for reshape), hence there is
no need to suspend the array if reshape is not done yet.
Meanwhile, there is a potential deadlock for raid456:
1) reshape is interrupted;
2) set one of the disk WantReplacement, and add a new disk to the array,
however, recovery won't start until the reshape is finished;
3) then issue an IO across reshpae position, this IO will wait for
reshape to make progress;
4) continue to reshape, then md_start_sync() found there is a spare disk
that can be added to conf, mddev_suspend() is called;
Step 4 and step 3 is waiting for each other, deadlock triggered. Noted
this problem is found by code review, and it's not reporduced yet.
Fix this porblem by don't suspend the array for interrupted reshape,
this is safe because conf won't be changed until reshape is done. |

crypto: virtio/akcipher - Fix stack overflow on memcpy
sizeof(struct virtio_crypto_akcipher_session_para) is less than
sizeof(struct virtio_crypto_op_ctrl_req::u), copying more bytes from
stack variable leads stack overflow. Clang reports this issue by

| In the Linux kernel, the following vulnerability has been resolved:
ARM: ep93xx: Add terminator to gpiod_lookup_table
Without the terminator, if a con_id is passed to gpio_find() that
does not exist in the lookup table the function will not stop looping
correctly, and eventually cause an oops. |
| In the Linux kernel, the following vulnerability has been resolved:
af_unix: Drop oob_skb ref before purging queue in GC.
syzbot reported another task hung in __unix_gc(). [0]
The current while loop assumes that all of the left candidates
have oob_skb and calling kfree_skb(oob_skb) releases the remaining
candidates.
However, I missed a case that oob_skb has self-referencing fd and
another fd and the latter sk is placed before the former in the
candidate list. Then, the while loop never proceeds, resulting
the task hung.
__unix_gc() has the same loop just before purging the collected skb,
so we can call kfree_skb(oob_skb) there and let __skb_queue_purge()
release all inflight sockets.

| In the Linux kernel, the following vulnerability has been resolved:
scsi: smartpqi: Fix disable_managed_interrupts
Correct blk-mq registration issue with module parameter
disable_managed_interrupts enabled.
When we turn off the default PCI_IRQ_AFFINITY flag, the driver needs to
register with blk-mq using blk_mq_map_queues(). The driver is currently
calling blk_mq_pci_map_queues() which results in a stack trace and possibly
undefined behavior.

| In the Linux kernel, the following vulnerability has been resolved:
dccp/tcp: Unhash sk from ehash for tb2 alloc failure after check_estalblished().
syzkaller reported a warning [0] in inet_csk_destroy_sock() with no
repro.
WARN_ON(inet_sk(sk)->inet_num && !inet_csk(sk)->icsk_bind_hash);
However, the syzkaller's log hinted that connect() failed just before
the warning due to FAULT_INJECTION. [1]
When connect() is called for an unbound socket, we search for an
available ephemeral port. If a bhash bucket exists for the port, we
call __inet_check_established() or __inet6_check_established() to check
if the bucket is reusable.
If reusable, we add the socket into ehash and set inet_sk(sk)->inet_num.
Later, we look up the corresponding bhash2 bucket and try to allocate
it if it does not exist.
Although it rarely occurs in real use, if the allocation fails, we must
revert the changes by check_established(). Otherwise, an unconnected
socket could illegally occupy an ehash entry.
Note that we do not put tw back into ehash because sk might have
already responded to a packet for tw and it would be better to free
tw earlier under such memory presure.
