[ Upstream commit cc9b364bb1d58d3dae270c7a931a8cc717dc2b3b ]
There are race conditions that may lead to inet6_dev refcount underflow
in xfrm6_dst_destroy() and rt6_uncached_list_flush_dev().
One of the refcount underflow bugs is shown below:
(cpu 1) | (cpu 2)
xfrm6_dst_destroy() |
... |
in6_dev_put() |
| rt6_uncached_list_flush_dev()
... | ...
| in6_dev_put()
rt6_uncached_list_del() | ...
... |
xfrm6_dst_destroy() calls rt6_uncached_list_del() after in6_dev_put(),
so rt6_uncached_list_flush_dev() has a chance to call in6_dev_put()
again for the same inet6_dev.
Fix it by moving in6_dev_put() after rt6_uncached_list_del() in
xfrm6_dst_destroy().

commit cb3871b1cd135a6662b732fbc6b3db4afcdb4a64 upstream.
The code pattern of memcpy(dst, src, strlen(src)) is almost always
wrong. In this case it is wrong because it leaves memory uninitialized
if it is less than sizeof(ni->name), and overflows ni->name when longer.
Normally strtomem_pad() could be used here, but since ni->name is a
trailing array in struct hci_mon_new_index, compilers that don't support
-fstrict-flex-arrays=3 can't tell how large this array is via
__builtin_object_size(). Instead, open-code the helper and use sizeof()
since it will work correctly.
Additionally mark ni->name as __nonstring since it appears to not be a
%NUL terminated C string.

[ Upstream commit 3b384cc74b00b5ac21d18e4c1efc3c1da5300971 ]
Looks like the driver sleep pins configuration is unusable. Adding the
sleep pins causes the usb phy to not respond. We need to use the default
pins in probe, and only set sleep pins at phy_mdm6600_device_power_off().
As the modem can also be booted to a serial port mode for firmware
flashing, let's make the pin changes limited to probe and remove. For
probe, we get the default pins automatically. We only need to set the
sleep pins in phy_mdm6600_device_power_off() to prevent the modem from
waking up because the gpio line glitches.
If it turns out that we need a separate state for phy_mdm6600_power_on()
and phy_mdm6600_power_off(), we can use the pinctrl idle state.

commit c1ae1c59c8c6e0b66a718308c623e0cb394dab6b upstream.
Since the fixed commits both zdev->iommu_bitmap and zdev->lazy_bitmap
are allocated as vzalloc(zdev->iommu_pages / 8). The problem is that
zdev->iommu_bitmap is a pointer to unsigned long but the above only
yields an allocation that is a multiple of sizeof(unsigned long) which
is 8 on s390x if the number of IOMMU pages is a multiple of 64.
This in turn is the case only if the effective IOMMU aperture is
a multiple of 64 * 4K = 256K. This is usually the case and so didn't
cause visible issues since both the virt_to_phys(high_memory) reduced
limit and hardware limits use nice numbers.
Under KVM, and in particular with QEMU limiting the IOMMU aperture to
the vfio DMA limit (default 65535), it is possible for the reported
aperture not to be a multiple of 256K however. In this case we end up
with an iommu_bitmap whose allocation is not a multiple of
8 causing bitmap operations to access it out of bounds.
Sadly we can't just fix this in the obvious way and use bitmap_zalloc()
because for large RAM systems (tested on 8 TiB) the zdev->iommu_bitmap
grows too large for kmalloc(). So add our own bitmap_vzalloc() wrapper.
This might be a candidate for common code, but this area of code will
be replaced by the upcoming conversion to use the common code DMA API on
s390 so just add a local routine.

commit 32671e3799ca2e4590773fd0e63aaa4229e50c06 upstream.
Because group consistency is non-atomic between parent (filedesc) and children
(inherited) events, it is possible for PERF_FORMAT_GROUP read() to try and sum
non-matching counter groups -- with non-sensical results.
Add group_generation to distinguish the case where a parent group removes and
adds an event and thus has the same number, but a different configuration of
events as inherited groups.
This became a problem when commit fa8c269353 ("perf/core: Invert
perf_read_group() loops") flipped the order of child_list and sibling_list.
Previously it would iterate the group (sibling_list) first, and for each
sibling traverse the child_list. In this order, only the group composition of
the parent is relevant. By flipping the order the group composition of the
child (inherited) events becomes an issue and the mis-match in group
composition becomes evident.
That said; even prior to this commit, while reading of a group that is not
equally inherited was not broken, it still made no sense.
(Ab)use ECHILD as error return to indicate issues with child process group
composition.

commit 84ee19bffc9306128cd0f1c650e89767079efeff upstream.
The OEMID is an 8-bit binary number rather than 16-bit as the current code
parses for. The OEMID occupies bits [111:104] in the CID register, see the
eMMC spec JESD84-B51 paragraph 7.2.3. It seems that the 16-bit comes from
the legacy MMC specs (v3.31 and before).
Let's fix the parsing by simply move to use 8-bit instead of 16-bit. This
means we ignore the impact on some of those old MMC cards that may be out
there, but on the other hand this shouldn't be a problem as the OEMID seems
not be an important feature for these cards.

that size should be 0. But the compiler now gets upset with 0 size arrays

array (it can't figure out that in this case an rx skb with fragments
would never be created). To keep the compiler happy, make sure there is
at least 1 frag_addr in struct rx_ring_info:

Lower layer device driver stop/wake TX by calling ieee80211_stop_queue()/
ieee80211_wake_queue() while hw scan. Sometimes hw scan and PTK rekey are
running in parallel, when M4 sent from wpa_supplicant arrive while the TX
queue is stopped, then the M4 will pending send, and then new key install
from wpa_supplicant. After TX queue wake up by lower layer device driver,
the M4 will be dropped by below call stack.
When key install started, the current key flag is set KEY_FLAG_TAINTED in
ieee80211_pairwise_rekey(), and then mac80211 wait key install complete by
lower layer device driver. Meanwhile ieee80211_tx_h_select_key() will return
TX_DROP for the M4 in step 12 below, and then ieee80211_free_txskb() called
by ieee80211_tx_dequeue(), so the M4 will not send and free, then the rekey
process failed becaue AP not receive M4. Please see details in steps below.
There are a interval between KEY_FLAG_TAINTED set for current key flag and
install key complete by lower layer device driver, the KEY_FLAG_TAINTED is
set in this interval, all packet including M4 will be dropped in this
interval, the interval is step 8~13 as below.
issue steps:
TX thread install key thread
1. stop_queue -idle-
2. sending M4 -idle-
3. M4 pending -idle-
4. -idle- starting install key from wpa_supplicant
5. -idle- =>ieee80211_key_replace()
6. -idle- =>ieee80211_pairwise_rekey() and set
currently key->flags |= KEY_FLAG_TAINTED
7. -idle- =>ieee80211_key_enable_hw_accel()
8. -idle- =>drv_set_key() and waiting key install
complete from lower layer device driver
9. wake_queue -waiting state-
10. re-sending M4 -waiting state-
11. =>ieee80211_tx_h_select_key() -waiting state-
12. drop M4 by KEY_FLAG_TAINTED -waiting state-
13. -idle- install key complete with success/fail
success: clear flag KEY_FLAG_TAINTED
fail: start disconnect
Hence add check in step 11 above to allow the EAPOL send out in the
interval. If lower layer device driver use the old key/cipher to encrypt
the M4, then AP received/decrypt M4 correctly, after M4 send out, lower
layer device driver install the new key/cipher to hardware and return
success.
If lower layer device driver use new key/cipher to send the M4, then AP
will/should drop the M4, then it is same result with this issue, AP will/
should kick out station as well as this issue.

While executing the Android 13 CTS Verifier Secure Server test on a
ChromeOS device, it was observed that the Bluetooth host initiates
authentication for an RFCOMM connection after SSP completes.
When this happens, some Intel Bluetooth controllers, like AC9560, would
disconnect with "Connection Rejected due to Security Reasons (0x0e)".
Historically, BlueZ did not mandate this authentication while an
authenticated combination key was already in use for the connection.
This behavior was changed since commit 7b5a9241b7
("Bluetooth: Introduce requirements for security level 4").
So, this patch addresses the aforementioned disconnection issue by
restoring the previous behavior.

There is a slab-out-of-bounds Write bug in hid-holtek-kbd driver.
The problem is the driver assumes the device must have an input
but some malicious devices violate this assumption.
Fix this by checking hid_device's input is non-empty before its usage.

[ Upstream commit 23cce5f25491968b23fb9c399bbfb25f13870cd9 ]
When kernel is compiled without preemption, the eval_map_work_func()
(which calls trace_event_eval_update()) will not be preempted up to its
complete execution. This can actually cause a problem since if another
CPU call stop_machine(), the call will have to wait for the
eval_map_work_func() function to finish executing in the workqueue
before being able to be scheduled. This problem was observe on a SMP
system at boot time, when the CPU calling the initcalls executed
clocksource_done_booting() which in the end calls stop_machine(). We
observed a 1 second delay because one CPU was executing
eval_map_work_func() and was not preempted by the stop_machine() task.
Adding a call to cond_resched() in trace_event_eval_update() allows
other tasks to be executed and thus continue working asynchronously
like before without blocking any pending task at boot time.

As timbgpio_irq_enable()/timbgpio_irq_disable() callback could be
executed under irq context, it could introduce double locks on
&tgpio->lock if it preempts other execution units requiring
the same locks.
timbgpio_gpio_set()
--> timbgpio_update_bit()
--> spin_lock(&tgpio->lock)
<interrupt>
--> timbgpio_irq_disable()
--> spin_lock_irqsave(&tgpio->lock)
This flaw was found by an experimental static analysis tool I am
developing for irq-related deadlock.
To prevent the potential deadlock, the patch uses spin_lock_irqsave()
on &tgpio->lock inside timbgpio_gpio_set() to prevent the possible
deadlock scenario.

Nathan reported that he was seeing the new warning in
setattr_copy_mgtime pop when starting podman containers. Overlayfs is
trying to set the atime and mtime via notify_change without also
setting the ctime.
POSIX states that when the atime and mtime are updated via utimes() that
we must also update the ctime to the current time. The situation with
overlayfs copy-up is analogies, so add ATTR_CTIME to the bitmask.
notify_change will fill in the value.

Jens reported a compiler warning when using
CONFIG_CC_OPTIMIZE_FOR_SIZE=y that looks like this
fs/btrfs/tree-log.c: In function ‘btrfs_log_prealloc_extents’:
fs/btrfs/tree-log.c:4828:23: warning: ‘start_slot’ may be used
uninitialized [-Wmaybe-uninitialized]
4828 | ret = copy_items(trans, inode, dst_path, path,

4829 | start_slot, ins_nr, 1, 0);
| ~~~~~~~~~~~~~~~~~~~~~~~~~
fs/btrfs/tree-log.c:4725:13: note: ‘start_slot’ was declared here
4725 | int start_slot;
| ^~~~~~~~~~
The compiler is incorrect, as we only use this code when ins_len > 0,
and when ins_len > 0 we have start_slot properly initialized. However
we generally find the -Wmaybe-uninitialized warnings valuable, so
initialize start_slot to get rid of the warning.

When running a delayed tree reference, if we find a ref count different
from 1, we return -EIO. This isn't an IO error, as it indicates either a
bug in the delayed refs code or a memory corruption, so change the error
code from -EIO to -EUCLEAN. Also tag the branch as 'unlikely' as this is
not expected to ever happen, and change the error message to print the
tree block's bytenr without the parenthesis (and there was a missing space
between the 'block' word and the opening parenthesis), for consistency as
that's the style we used everywhere else.
