The ieee80211_tx_info_clear_status() helper also clears the rate counts and
the driver-private part of struct ieee80211_tx_info, so using it breaks
quite a few other things. So back out of using it, and instead define a
ath-internal helper that only clears the area between the
status_driver_data and the rates info. Combined with moving the
ath_frame_info struct to status_driver_data, this avoids clearing anything
we shouldn't be, and so we can keep the existing code for handling the rate
information.
While fixing this I also noticed that the setting of
tx_info->status.rates[tx_rateindex].count on hardware underrun errors was
always immediately overridden by the normal setting of the same fields, so
rearrange the code so that the underrun detection actually takes effect.
The new helper could be generalised to a 'memset_between()' helper, but
leave it as a driver-internal helper for now since this needs to go to
stable.

Fix firmware file names assignment in si2157 tuner, allow for running
devices without firmware files needed.
modprobe gives error: unknown chip version Si2147-A30 ROM 0x50
Device initialization is interrupted.
Caused by:
1. table si2157_tuners has swapped fields rom_id and required vs struct
si2157_tuner_info.
2. both firmware file names can be null for devices with
required == false - device uses build-in firmware in this case

When a driver for an interrupt controller is missing, of_irq_get()
returns -EPROBE_DEFER ad infinitum, causing
fwnode_mdiobus_phy_device_register(), and ultimately, the entire
of_mdiobus_register() call, to fail. In turn, any phy_connect() call
towards a PHY on this MDIO bus will also fail.
This is not what is expected to happen, because the PHY library falls
back to poll mode when of_irq_get() returns a hard error code, and the
MDIO bus, PHY and attached Ethernet controller work fine, albeit
suboptimally, when the PHY library polls for link status. However,
-EPROBE_DEFER has special handling given the assumption that at some
point probe deferral will stop, and the driver for the supplier will
kick in and create the IRQ domain.
Reasons for which the interrupt controller may be missing:
- It is not yet written. This may happen if a more recent DT blob (with
an interrupt-parent for the PHY) is used to boot an old kernel where
the driver didn't exist, and that kernel worked with the
vintage-correct DT blob using poll mode.
- It is compiled out. Behavior is the same as above.
- It is compiled as a module. The kernel will wait for a number of
seconds specified in the "deferred_probe_timeout" boot parameter for
user space to load the required module. The current default is 0,
which times out at the end of initcalls. It is possible that this
might cause regressions unless users adjust this boot parameter.
The proposed solution is to use the driver_deferred_probe_check_state()
helper function provided by the driver core, which gives up after some
-EPROBE_DEFER attempts, taking "deferred_probe_timeout" into consideration.
The return code is changed from -EPROBE_DEFER into -ENODEV or
-ETIMEDOUT, depending on whether the kernel is compiled with support for
modules or not.

Under certain conditions, such as MPI_Abort, the hfi1 cleanup code may
represent the last reference held on the task mm.
hfi1_mmu_rb_unregister() then drops the last reference and the mm is freed
before the final use in hfi1_release_user_pages(). A new task may
allocate the mm structure while it is still being used, resulting in
problems. One manifestation is corruption of the mmap_sem counter leading
to a hang in down_write(). Another is corruption of an mm struct that is
in use by another task.

This is due to that free_irq_cpu_rmap() is always being called
*after* (devm_)free_irq() and thus it tries to work with IRQ descs
already freed. For example, on device reset the driver frees the
rmap right before allocating a new one (the splat above).
Make rmap creation and freeing function symmetrical with
{request,free}_irq() calls i.e. do that on ifup/ifdown instead
of device probe/remove/resume. These operations can be performed
independently from the actual device aRFS configuration.
Also, make sure ice_vsi_free_irq() clears IRQ affinity notifiers
only when aRFS is disabled -- otherwise, CPU rmap sets and clears
its own and they must not be touched manually.

A pin that comes from ACPI tables is of unsigned type. This also applies
to the internal APIs which use unsigned int to store the pin. Convert
type for pin to be unsigned in the places where it's not yet true.
While at it, add a stub for acpi_get_and_request_gpiod() for the sake
of consistency in the APIs.

When compiling with -Wformat, clang emits the following warning:
gpiolib-acpi.c:393:4: warning: format specifies type 'unsigned char' but the argument has type 'int' [-Wformat]
pin);
^~~
So warning that '%hhX' is paired with an 'int' is all just completely
mindless and wrong. Sadly, I can see a different bogus warning reason
why people would want to use '%02hhX'.
Again, the *sane* thing from a human perspective is to use '%02X. But
if the compiler doesn't do any range analysis at all, it could decide
that "Oh, that print format could need up to 8 bytes of space in the
result". Using '%02hhX' would cut that down to two.
And since we use
char ev_name[5];
and currently use "_%c%02hhX" as the format string, even a compiler
that doesn't notice that "pin <= 255" test that guards this all will
go "OK, that's at most 4 bytes and the final NUL termination, so it's
fine".
While a compiler - like gcc - that only sees that the original source
of the 'pin' value is a 'unsigned short' array, and then doesn't take
the "pin <= 255" into account, will warn like this:
gpiolib-acpi.c: In function 'acpi_gpiochip_request_interrupt':
gpiolib-acpi.c:206:24: warning: '%02X' directive writing between 2 and 4 bytes into a region of size 3 [-Wformat-overflow=]
sprintf(ev_name, "_%c%02X",
^~~~
gpiolib-acpi.c:206:20: note: directive argument in the range [0, 65535]
because gcc isn't being very good at that argument range analysis either.
In other words, the original use of 'hhx' was bogus to begin with, and
due to *another* compiler warning being bad, and we had that bad code
being written back in 2016 to work around _that_ compiler warning
(commit e40a3ae1f794: "gpio: acpi: work around false-positive
-Wstring-overflow warning").
Sadly, two different bad compiler warnings together does not make for
one good one.
It just makes for even more pain.
End result: I think the simplest and cleanest option is simply the
proposed change which undoes that '%hhX' change for gcc, and replaces
it with just using a slightly bigger stack allocation. It's not like
a 5-byte allocation is in any way likely to have saved any actual stack,
since all the other variables in that function are 'int' or bigger.
False-positive compiler warnings really do make people write worse
code, and that's a problem. But on a scale of bad code, I feel that
extending the buffer trivially is better than adding a pointless cast
that literally makes no sense.
At least in this case the end result isn't unreadable or buggy. We've
had several cases of bad compiler warnings that caused changes that
were actually horrendously wrong.

After feeding a decapsulated packet to a veth device with act_mirred,
skb_headlen() may be 0. But veth_xmit() calls __dev_forward_skb(),
which expects at least ETH_HLEN byte of linear data (as
__dev_forward_skb2() calls eth_type_trans(), which pulls ETH_HLEN bytes
unconditionally).
Use pskb_may_pull() to ensure veth_xmit() respects this constraint.

Commit 3f6634d997db ("iommu: Use right way to retrieve iommu_ops") started
triggering a NULL pointer dereference for some omap variants:
__iommu_probe_device from probe_iommu_group+0x2c/0x38
probe_iommu_group from bus_for_each_dev+0x74/0xbc
bus_for_each_dev from bus_iommu_probe+0x34/0x2e8

bus_set_iommu from omap_iommu_init+0x88/0xcc
omap_iommu_init from do_one_initcall+0x44/0x24
This is caused by omap iommu probe returning 0 instead of ERR_PTR(-ENODEV)
as noted by Jason Gunthorpe <jgg@ziepe.ca>.
Looks like the regression already happened with an earlier commit
6785eb9105e3 ("iommu/omap: Convert to probe/release_device() call-backs")
that changed the function return type and missed converting one place.

Pull random number generator fixes from Jason Donenfeld:
- Another fixup to the fast_init/crng_init split, this time in how much
entropy is being credited, from Jan Varho.
- As discussed, we now opportunistically call try_to_generate_entropy()
in /dev/urandom reads, as a replacement for the reverted commit. I
opted to not do the more invasive wait_for_random_bytes() change at
least for now, preferring to do something smaller and more obvious
for the time being, but maybe that can be revisited as things evolve
later.
- Userspace can use FUSE or userfaultfd or simply move a process to
idle priority in order to make a read from the random device never
complete, which breaks forward secrecy, fixed by overwriting
sensitive bytes early on in the function.
- Jann Horn noticed that /dev/urandom reads were only checking for
pending signals if need_resched() was true, a bug going back to the
genesis commit, now fixed by always checking for signal_pending() and
calling cond_resched(). This explains various noticeable signal
delivery delays I've seen in programs over the years that do long
reads from /dev/urandom.
- In order to be more like other devices (e.g. /dev/zero) and to
mitigate the impact of fixing the above bug, which has been around
forever (users have never really needed to check the return value of
read() for medium-sized reads and so perhaps many didn't), we now
move signal checking to the bottom part of the loop, and do so every
PAGE_SIZE-bytes.

Memory controller drivers - fixes for v5.18
Issues in v5.18:
1. Freescale/NXP: fix populating children of Integrated Flash Controller
DT nodes.
Issues existing before:
1. Renesas: fix platform-device leak in probe's error path.
2. Atmel: fix of_node reference leak in probe's error path.
3. Synopsys: correct the bindings for snps,ddrc-3.80a (interrupts are
required).

When HS400 tuning is complete and HS400 is going to be activated, we
have to keep the current number of TAPs and should not overwrite them
with a hardcoded value. This was probably a copy&paste mistake when
upporting HS400 support from the BSP.
Fixes: 26eb2607fa28 ("mmc: renesas_sdhi: add eMMC HS400 mode support")

When a slip driver is detaching, the slip_close() will act to
cleanup necessary resources and sl->tty is set to NULL in
slip_close(). Meanwhile, the packet we transmit is blocked,
sl_tx_timeout() will be called. Although slip_close() and
sl_tx_timeout() use sl->lock to synchronize, we don`t judge
whether sl->tty equals to NULL in sl_tx_timeout() and the
null pointer dereference bug will happen.
(Thread 1) | (Thread 2)
| slip_close()
| spin_lock_bh(&sl->lock)
| ...
... | sl->tty = NULL //(1)
sl_tx_timeout() | spin_unlock_bh(&sl->lock)
spin_lock(&sl->lock); |
... | ...
tty_chars_in_buffer(sl->tty)|
if (tty->ops->..) //(2) |
... | synchronize_rcu()
We set NULL to sl->tty in position (1) and dereference sl->tty
in position (2).
This patch adds check in sl_tx_timeout(). If sl->tty equals to
NULL, sl_tx_timeout() will goto out.

The megaraid_sas driver supports single LUN for RAID devices. That is LUN
0. All other LUNs are unsupported. When a device scan on a logical target
with invalid LUN number is invoked through sysfs, that target ends up
getting removed.
Add LUN ID validation in the slave destroy function to avoid the target
deletion.

The list iterator is always non-NULL so the check 'if (!rgn)' is always
false and the dev_err() is never called. Move the check outside the loop
and determine if 'victim_rgn' is NULL, to fix this bug.

We forgot to call blk_cleanup_disk() when device_add_disk() failed. This
would cause a memory leak of gendisk and sched_tags allocated in
elevator_init_mq()
