From: Will McVicker <willmcvicker@google.com>

commit ed9be64eefe26d7d8b0b5b9fa3ffdf425d87a01f upstream.

The HID subsystem allows an "HID report field" to have a different
number of "values" and "usages" when it is allocated. When a field
struct is created, the size of the usage array is guaranteed to be at
least as large as the values array, but it may be larger. This leads to
a potential out-of-bounds write in
__hidinput_change_resolution_multipliers() and an out-of-bounds read in
hidinput_count_leds().

To fix this, let's make sure that both the usage and value arrays are
the same size.

From: Sameer Pujar <spujar@nvidia.com>

commit 1e0ca5467445bc1f41a9e403d6161a22f313dae7 upstream.

HDA initialization is failing occasionally on Tegra210 and following
print is observed in the boot log. Because of this probe() fails and
no sound card is registered.

  [16.800802] tegra-hda 70030000.hda: no codecs found!

Codecs request a state change and enumeration by the controller. In
failure cases this does not seem to happen as STATETS register reads 0.

The problem seems to be related to the HDA codec dependency on SOR
power domain. If it is gated during HDA probe then the failure is
observed. Building Tegra HDA driver into kernel image avoids this

problem by adding 'power-domains' DT property for Tegra210 HDA. Note

commit 2cea4a7a1885bd0c765089afc14f7ff0eb77864e upstream.

Otherwise build fails if the headers are not in the default location. While at
it also ask pkg-config for the libs, with fallback to the existing value.

From: Ming Lei <ming.lei@redhat.com>

commit cecf5d87ff2035127bb5a9ee054d0023a4a7cad3 upstream.

The kernfs built-in lock of 'kn->count' is held in sysfs .show/.store
path. Meantime, inside block's .show/.store callback, q->sysfs_lock is
required.

However, when mq & iosched kobjects are removed via
blk_mq_unregister_dev() & elv_unregister_queue(), q->sysfs_lock is held
too. This way causes AB-BA lock because the kernfs built-in lock of
'kn-count' is required inside kobject_del() too, see the lockdep warning[1].

On the other hand, it isn't necessary to acquire q->sysfs_lock for
both blk_mq_unregister_dev() & elv_unregister_queue() because
clearing REGISTERED flag prevents storing to 'queue/scheduler'
from being happened. Also sysfs write(store) is exclusive, so no
necessary to hold the lock for elv_unregister_queue() when it is
called in switching elevator path.

So split .sysfs_lock into two: one is still named as .sysfs_lock for
covering sync .store, the other one is named as .sysfs_dir_lock
for covering kobjects and related status change.

sysfs itself can handle the race between add/remove kobjects and
showing/storing attributes under kobjects. For switching scheduler
via storing to 'queue/scheduler', we use the queue flag of
QUEUE_FLAG_REGISTERED with .sysfs_lock for avoiding the race, then
we can avoid to hold .sysfs_lock during removing/adding kobjects.

commit 0a67b5a926e63ff5492c3c675eab5900580d056d upstream.

cecf5d87ff20 ("block: split .sysfs_lock into two locks") starts to
release & actuire sysfs_lock again during switching elevator. So it
isn't enough to prevent switching elevator from happening by simply
clearing QUEUE_FLAG_REGISTERED with holding sysfs_lock, because
in-progress switch still can move on after re-acquiring the lock,
meantime the flag of QUEUE_FLAG_REGISTERED won't get checked.

Fixes this issue by checking 'q->elevator' directly & locklessly after
q->kobj is removed in blk_unregister_queue(), this way is safe because
q->elevator can't be changed at that time.

commit b89f625e28d44552083f43752f62d8621ded0a04 upstream.

cecf5d87ff20 ("block: split .sysfs_lock into two locks") starts to
release & acquire sysfs_lock before registering/un-registering elevator
queue during switching elevator for avoiding potential deadlock from
showing & storing 'queue/iosched' attributes and removing elevator's
kobject.

Turns out there isn't such deadlock because 'q->sysfs_lock' isn't
required in .show & .store of queue/iosched's attributes, and just
elevator's sysfs lock is acquired in elv_iosched_store() and
elv_iosched_show(). So it is safe to hold queue's sysfs lock when
registering/un-registering elevator queue.

The biggest issue is that commit cecf5d87ff20 assumes that concurrent
write on 'queue/scheduler' can't happen. However, this assumption isn't
true, because kernfs_fop_write() only guarantees that concurrent write
aren't called on the same open file, but the write could be from
different open on the file. So we can't release & re-acquire queue's
sysfs lock during switching elevator, otherwise use-after-free on
elevator could be triggered.

Fixes the issue by not releasing queue's sysfs lock during switching
elevator.

[ Upstream commit a738c93fb1c17e386a09304b517b1c6b2a6a5a8b ]

While debugging another issue today, Steve and I noticed that if a
subdir for a file share is already mounted on the client, any new
mount of any other subdir (or the file share root) of the same share
results in sharing the cifs superblock, which e.g. can result in
incorrect device name.

While setting prefix path for the root of a cifs_sb,
CIFS_MOUNT_USE_PREFIX_PATH flag should also be set.
Without it, prepath is not even considered in some places,
and output of "mount" and various /proc/<>/*mount* related
options can be missing part of the device name.

[ Upstream commit 93ca696376dd3d44b9e5eae835ffbc84772023ec ]

The kernel test robot reported the following issue:

    CC [M]  drivers/soc/litex/litex_soc_ctrl.o
  sh4-linux-objcopy: Unable to change endianness of input file(s)
  sh4-linux-ld: cannot find drivers/soc/litex/.tmp_gl_litex_soc_ctrl.o: No such file or directory
  sh4-linux-objcopy: 'drivers/soc/litex/.tmp_mx_litex_soc_ctrl.o': No such file

The problem is that the format of input file is elf32-shbig-linux, but
sh4-linux-objcopy wants to output a file which format is elf32-sh-linux:

  $ sh4-linux-objdump -d drivers/soc/litex/litex_soc_ctrl.o | grep format
  drivers/soc/litex/litex_soc_ctrl.o:     file format elf32-shbig-linux

From: Peter Zijlstra <peterz@infradead.org>

commit a1247d06d01045d7ab2882a9c074fbf21137c690 upstream.

Even though the atomic_dec_and_mutex_lock() in
__static_key_slow_dec_cpuslocked() can never see a negative value in
key->enabled the subsequent sanity check is re-reading key->enabled, which may
have been set to -1 in the meantime by static_key_slow_inc_cpuslocked().

                CPU  A                               CPU B

 __static_key_slow_dec_cpuslocked():          static_key_slow_inc_cpuslocked():
                               # enabled = 1
   atomic_dec_and_mutex_lock()
                               # enabled = 0
                                              atomic_read() == 0
                                              atomic_set(-1)
                               # enabled = -1
   val = atomic_read()
   # Oops - val == -1!

The test case is TCP's clean_acked_data_enable() / clean_acked_data_disable()
as tickled by KTLS (net/ktls).

From: Nick Desaulniers <ndesaulniers@google.com>

commit 3c4fa46b30c551b1df2fb1574a684f68bc22067c upstream.

We expect toolchains to produce these new debug info sections as part of
DWARF v5. Add explicit placements to prevent the linker warnings from
--orphan-section=warn.

Compilers may produce such sections with explicit -gdwarf-5, or based on
the implicit default version of DWARF when -g is used via DEBUG_INFO.
This implicit default changes over time, and has changed to DWARF v5
with GCC 11.

.debug_sup was mentioned in review, but without compilers producing it
today, let's wait to add it until it becomes necessary.

From: Sumit Garg <sumit.garg@linaro.org>

commit 93f7a6d818deef69d0ba652d46bae6fbabbf365c upstream.

Currently kdb uses in_interrupt() to determine whether its library
code has been called from the kgdb trap handler or from a saner calling
context such as driver init. This approach is broken because
in_interrupt() alone isn't able to determine kgdb trap handler entry from
normal task context. This can happen during normal use of basic features
such as breakpoints and can also be trivially reproduced using:
echo g > /proc/sysrq-trigger

We can improve this by adding check for in_dbg_master() instead which
explicitly determines if we are running in debugger context.

commit 2cfef1971aea6119ee27429181d6cb3383031ac2 upstream.

The use of PHY_REFCLK_USE_PAD introduced a regression for apq8064 devices.
It was tested that while apq doesn't require the padding, ipq SoC must use
it or the kernel hangs on boot.

From: Jan Kara <jack@suse.cz>

commit 41e76c85660c022c6bf5713bfb6c21e64a487cec upstream.

bfq_setup_cooperator() uses bfqd->in_serv_last_pos so detect whether it
makes sense to merge current bfq queue with the in-service queue.
However if the in-service queue is freshly scheduled and didn't dispatch
any requests yet, bfqd->in_serv_last_pos is stale and contains value
from the previously scheduled bfq queue which can thus result in a bogus
decision that the two queues should be merged. This bug can be observed
for example with the following fio jobfile:

[global]
direct=0
ioengine=sync
invalidate=1
size=1g
rw=read

[reader]
numjobs=4
directory=/mnt

where the 4 processes will end up in the one shared bfq queue although
they do IO to physically very distant files (for some reason I was able to
observe this only with slice_idle=1ms setting).

Fix the problem by invalidating bfqd->in_serv_last_pos when switching
in-service queue.

From: Takashi Iwai <tiwai@suse.de>

commit fb3c293b82c31a9a68fbcf4e7a45fadd8a47ea2b upstream.

The commit f274baa49be6 ("ALSA: usb-audio: Allow non-vmalloc buffer
for PCM buffers") introduced the mode to allocate coherent pages for
PCM buffers, and it used bus->controller device as its DMA device.
It turned out, however, that bus->sysdev is a more appropriate device
to be used for DMA mapping in HCD code.

This patch corrects the device reference accordingly.

Note that, on most platforms, both point to the very same device,
hence this patch doesn't change anything practically.  But on
platforms like xhcd-plat hcd, the change becomes effective.

From: Alexander Lobakin <alobakin@pm.me>

commit 8ac7c87acdcac156670f9920c8acbd84308ff4b1 upstream.

MIPS uses its own declaration of rwdata, and thus it should be kept
in sync with the asm-generic one. Currently PAGE_ALIGNED_DATA() is
missing from the linker script, which emits the following ld
warnings:

mips-alpine-linux-musl-ld: warning: orphan section
`.data..page_aligned' from `arch/mips/kernel/vdso.o' being placed
in section `.data..page_aligned'
mips-alpine-linux-musl-ld: warning: orphan section
`.data..page_aligned' from `arch/mips/vdso/vdso-image.o' being placed
in section `.data..page_aligned'

Add the necessary declaration, so the mentioned structures will be
placed in vmlinux as intended:

ffffffff80630580 D __end_once
ffffffff80630580 D __start___dyndbg
ffffffff80630580 D __start_once

[ Upstream commit cb31334687db31c691901269d65074a7ffaecb18 ]

The Samsung PMIC datasheets describe the interrupt line as active low
with a requirement of acknowledge from the CPU.  Without specifying the
interrupt type in Devicetree, kernel might apply some fixed
configuration, not necessarily working for this hardware.

[ Upstream commit 6943c2b05bf09fd5c5729f7d7d803bf3f126cb9a ]

BPF interpreter uses extra input argument, so re-casts __bpf_call_base into
__bpf_call_base_args. Avoid compiler warning about incompatible function
prototypes by casting to void * first.

[ Upstream commit cc72570747e43335f4933a24dd74d5653639176a ]

In recent Allwinner SoCs the first USB host controller (HCI0) shares
the first PHY with the MUSB controller. Probably to make this sharing
work, we were avoiding to declare this in the DT. This has two
shortcomings:
- U-Boot (which uses the same .dts) cannot use this port in host mode
  without a PHY linked, so we were loosing one USB port there.
- It requires the MUSB driver to be enabled and loaded, although we
  don't actually use it.

To avoid those issues, let's add this PHY link to the A64 .dtsi file.
After all PHY port 0 *is* connected to HCI0, so we should describe
it as this. Remove the part from the Pinebook DTS which already had
this property.

This makes it work in U-Boot, also improves compatiblity when no MUSB
driver is loaded (for instance in distribution installers).

[ Upstream commit 941432d007689f3774646e41a1439228b6c6ee0e ]

The SD card on the SoPine SoM module is somewhat concealed, so was
originally defined as "non-removable".
However there is a working card-detect pin (tested on two different
SoM versions), and in certain SoM base boards it might be actually
accessible at runtime.
Also the Pine64-LTS shares the SoPine base .dtsi, so inherited the
non-removable flag, even though the SD card slot is perfectly accessible
and usable there. (It turns out that just *my* board has a broken card
detect switch, so I originally thought CD wouldn't work on the LTS.)

Drop the "non-removable" flag to describe the SD card slot properly.

[ Upstream commit 948c657cc45e8ce48cb533d4e2106145fa765759 ]

In contrast to the H6 (and later) manuals, the A64 datasheet does not
specify any limitations in the maximum possible frequency for eMMC
controllers.
However experimentation has found that a 150 MHz limit similar to other
SoCs and also the MMC0 and MMC1 controllers on the A64 seems to exist
for the MMC2 controller.

Limit the frequency for the MMC2 controller to 150 MHz in the SoC .dtsi.
The Pinebook seems to be the an odd exception, since it apparently seems
to work with 200 MHz as well, so overwrite this in its board .dts file.

Tested on a Pine64-LTS: 200 MHz HS-200 fails, 150 MHz HS-200 works.

[ Upstream commit 05f456286fd489558c72a4711d22a5612c965685 ]

If 'cpufreq_register_driver()' fails, we must release the resources
allocated in 'brcm_avs_prepare_init()' as already done in the remove
function.

To do that, introduce a new function 'brcm_avs_prepare_uninit()' in order
to avoid code duplication. This also makes the code more readable (IMHO).

[ Upstream commit 3dfaea3811f8b6a89a347e8da9ab862cdf3e30fe ]

ACPICA commit 1a3a549286ea9db07d7ec700e7a70dd8bcc4354e

The macros to classify different AML exception codes are broken. For
instance,

  ACPI_ENV_EXCEPTION(Status)

will always evaluate to zero due to

  #define AE_CODE_ENVIRONMENTAL      0x0000
  #define ACPI_ENV_EXCEPTION(Status) (Status & AE_CODE_ENVIRONMENTAL)

Similarly, ACPI_AML_EXCEPTION(Status) will evaluate to a non-zero
value for error codes of type AE_CODE_PROGRAMMER, AE_CODE_ACPI_TABLES,
as well as AE_CODE_AML, and not just AE_CODE_AML as the name suggests.

This commit fixes those checks.

From: Jack Pham <jackp@codeaurora.org>

[ Upstream commit 7de8681be2cde9f6953d3be1fa6ce05f9fe6e637 ]

As per the kernel doc for usb_ep_dequeue(), it states that "this
routine is asynchronous, that is, it may return before the completion
routine runs". And indeed since v5.0 the dwc3 gadget driver updated
its behavior to place dequeued requests on to a cancelled list to be
given back later after the endpoint is stopped.

The free_ep() was incorrectly assuming that a request was ready to
be freed after calling dequeue which results in a use-after-free
in dwc3 when it traverses its cancelled list. Fix this by moving
the usb_ep_free_request() call to the callback itself in case the
ep is disabled.

[ Upstream commit 44f416879a442600b006ef7dec3a6dc98bcf59c6 ]

We have gpio_86 wired internally to the bandgap thermal shutdown
interrupt on 4430 like we have it on 4460 according to the TRM.
This can be found easily by searching for TSHUT.

For some reason the thermal shutdown interrupt was never added
for 4430, let's add it. I believe this is needed for the thermal
shutdown interrupt handler ti_bandgap_tshut_irq_handler() to call
orderly_poweroff().

[ Upstream commit 415fa1c7305dedbb345e2cc8ac91769bc1c83f1a ]

The DWC2 documentation states that transfers with zero data length should
set the number of packets to 1 and the transfer length to 0. This is not
currently the case for inbound transfers: the transfer length is set to
the maximum packet length. This can have adverse effects if the chip
actually does transfer data as it is programmed to do. Follow chip
documentation and keep the transfer length set to 0 in that situation.

From: Guenter Roeck <linux@roeck-us.net>

[ Upstream commit f74b68c61cbc4b2245022fcce038509333d63f6f ]

In some situations, the following error messages are reported.

dwc2 ff540000.usb: dwc2_hc_chhltd_intr_dma: Channel 1 - ChHltd set, but reason is unknown
dwc2 ff540000.usb: hcint 0x00000002, intsts 0x04000021

This is sometimes followed by:

dwc2 ff540000.usb: dwc2_update_urb_state_abn(): trimming xfer length

and then:

WARNING: CPU: 0 PID: 0 at kernel/v4.19/drivers/usb/dwc2/hcd.c:2913
			dwc2_assign_and_init_hc+0x98c/0x990

The warning suggests that an odd buffer address is to be used for DMA.

After an error is observed, the receive buffer may be full
(urb->actual_length >= urb->length). However, the urb is still left in
the queue unless three errors were observed in a row. When it is queued
again, the dwc2 hcd code translates this into a 1-block transfer.
If urb->actual_length (ie the total expected receive length) is not
DMA-aligned, the buffer pointer programmed into the chip will be
unaligned. This results in the observed warning.

To solve the problem, abort input transactions after an error with
unknown cause if the entire packet was already received. This may be
a bit drastic, but we don't really know why the transfer was aborted
even though the entire packet was received. Aborting the transfer in
this situation is less risky than accepting a potentially corrupted
packet.

With this patch in place, the 'ChHltd set' and 'trimming xfer length'
messages are still observed, but there are no more transfer attempts
with odd buffer addresses.

[ Upstream commit 1a9e38cabd80356ffb98c2c88fec528ea9644fd5 ]

With some USB network adapters, such as DM96xx, the following message
is seen for each maximum size receive packet.

dwc2 ff540000.usb: dwc2_update_urb_state(): trimming xfer length

This happens because the packet size requested by the driver is 1522
bytes, wMaxPacketSize is 64, the dwc2 driver configures the chip to
receive 24*64 = 1536 bytes, and the chip does indeed send more than
1522 bytes of data. Since the event does not indicate an error condition,
the message is just noise. Demote it to debug level.

From: Chen-Yu Tsai <wens@csie.org>

[ Upstream commit 61834c967a929f6b4b7fcb91f43fa225cc29aa19 ]

The custom regulatory ruleset in the rtl8723bs driver lists an incorrect
number of rules: one too many. This results in an out-of-bounds access,
as detected by KASAN. This was possible thanks to the newly added support
for KASAN on ARMv7.

Fix this by filling in the correct number of rules given.

[ Upstream commit 7f9942c61fa60eda7cc8e42f04bd25b7d175876e ]

Building with the clang integrated assembler produces a couple of
errors for the s3c24xx fiq support:

  arch/arm/mach-s3c/irq-s3c24xx-fiq.S:52:2: error: instruction 'subne' can not set flags, but 's' suffix specified
    subnes pc, lr, #4 @@ return, still have work to do

  arch/arm/mach-s3c/irq-s3c24xx-fiq.S:64:1: error: invalid symbol redefinition
    s3c24xx_spi_fiq_txrx:

There are apparently two problems: one with extraneous or duplicate
labels, and one with old-style opcode mnemonics. Stefan Agner has
previously fixed other problems like this, but missed this particular
file.

[ Upstream commit 3f94cf15583be554df7aaa651b8ff8e1b68fbe51 ]

If LPC SNOOP driver is registered ahead of lpc-ctrl module, LPC
SNOOP block will be enabled without heart beating of LCLK until
lpc-ctrl enables the LCLK. This issue causes improper handling on
host interrupts when the host sends interrupt in that time frame.
Then kernel eventually forcibly disables the interrupt with
dumping stack and printing a 'nobody cared this irq' message out.

To prevent this issue, all LPC sub-nodes should enable LCLK
individually so this patch adds clock control logic into the LPC
SNOOP driver.

[ Upstream commit 6df8fb83301d68ea0a0c0e1cbcc790fcc333ed12 ]

For double-checked locking in bpf_common_lru_push_free(), node->type is
read outside the critical section and then re-checked under the lock.
However, concurrent writes to node->type result in data races.

For example, the following concurrent access was observed by KCSAN:

  write to 0xffff88801521bc22 of 1 bytes by task 10038 on cpu 1:
   __bpf_lru_node_move_in        kernel/bpf/bpf_lru_list.c:91
   __local_list_flush            kernel/bpf/bpf_lru_list.c:298
   ...
  read to 0xffff88801521bc22 of 1 bytes by task 10043 on cpu 0:
   bpf_common_lru_push_free      kernel/bpf/bpf_lru_list.c:507
   bpf_lru_push_free             kernel/bpf/bpf_lru_list.c:555
   ...

Fix the data races where node->type is read outside the critical section
(for double-checked locking) by marking the access with READ_ONCE() as
well as ensuring the variable is only accessed once.

The "REG_READ(ah, AR_PHY_AGC_CONTROL)" in ath9k_hw_loadnf() does not
like being called when the hardware is asleep, leading to this crash.

The easiest way to reproduce this is trying to set nf_override while
the hardware is down:

  $ ip link set down dev wlan0
  $ echo "-85" > /sys/kernel/debug/ieee80211/phy0/ath9k/nf_override

Fixing this crash by waking the hardware up before trying to set the
noise floor. Similar to what other ath9k debugfs files do.

Tested on a Lima board from 8devices, which has a QCA 4531 chipset.

If set_link_state() fails for any reason, we still cleanup the adapter
state and cannot recover from a partial close anyway. So set the adapter
to CLOSED state. That way if a new soft/hard reset is processed, the
adapter will remain in the CLOSED state until the next ibmvnic_open().

In case of a common event for rx and tx queue the event should be
regarded to be spurious if no rx and no tx requests are pending.

Unfortunately the condition for testing that is wrong causing to
decide a event being spurious if no rx OR no tx requests are
pending.

Fix that plus using local variables for rx/tx pending indicators in
order to split function calls and if condition.

From: Jesper Dangaard Brouer <brouer@redhat.com>

[ Upstream commit 2c0a10af688c02adcf127aad29e923e0056c6b69 ]

BPF end-user on Cilium slack-channel (Carlo Carraro) wants to use
bpf_fib_lookup for doing MTU-check, but *prior* to extending packet size,
by adjusting fib_params 'tot_len' with the packet length plus the expected
encap size. (Just like the bpf_check_mtu helper supports). He discovered
that for SKB ctx the param->tot_len was not used, instead skb->len was used
(via MTU check in is_skb_forwardable() that checks against netdev MTU).

Fix this by using fib_params 'tot_len' for MTU check. If not provided (e.g.
zero) then keep existing TC behaviour intact. Notice that 'tot_len' for MTU
check is done like XDP code-path, which checks against FIB-dst MTU.

V16:
- Revert V13 optimization, 2nd lookup is against egress/resulting netdev

V13:
- Only do ifindex lookup one time, calling dev_get_by_index_rcu().

V10:
- Use same method as XDP for 'tot_len' MTU check

[ Upstream commit f969dc5a885736842c3511ecdea240fbb02d25d9 ]

While commit 24adbc1676af ("tcp: fix SO_RCVLOWAT hangs with fat skbs")
fixed an issue vs too small sk_rcvbuf for given sk_rcvlowat constraint,
it missed to address issue caused by memory pressure.

1) If we are under memory pressure and socket receive queue is empty.
First incoming packet is allowed to be queued, after commit
76dfa6082032 ("tcp: allow one skb to be received per socket under memory pressure")

But we do not send EPOLLIN yet, in case tcp_data_ready() sees sk_rcvlowat
is bigger than skb length.

2) Then, when next packet comes, it is dropped, and we directly
call sk->sk_data_ready().

3) If application is using poll(), tcp_poll() will then use
tcp_stream_is_readable() and decide the socket receive queue is
not yet filled, so nothing will happen.

Even when sender retransmits packets, phases 2) & 3) repeat
and flow is effectively frozen, until memory pressure is off.

Fix is to consider tcp_under_memory_pressure() to take care
of global memory pressure or memcg pressure.

[ Upstream commit 2355a6773a2cb0d2dce13432dde78497f1d6617b ]

The Max imm data size in cxgb4 is not similar to the max imm data size
in the chtls. This caused an mismatch in output of is_ofld_imm() of
cxgb4 and chtls. So fixed this by keeping the max wreq size of imm data
same in both chtls and cxgb4 as MAX_IMM_OFLD_TX_DATA_WR_LEN.

As cxgb4's max imm. data value for ofld packets is changed to
MAX_IMM_OFLD_TX_DATA_WR_LEN. Using the same in cxgbit also.

From: Colin Ian King <colin.king@canonical.com>

[ Upstream commit 4773acf3d4b50768bf08e9e97a204819e9ea0895 ]

The documentation for the PHY update [1] states:

Loop 4 times with index i

    If PHY Revision >= 3
        Copy table[i] to coef[i]
    Otherwise
        Set coef[i] to 0

the copy of the table to coef is currently implemented the wrong way
around, table is being updated from uninitialized values in coeff.
Fix this by swapping the assignment around.

it to socket buffer; and dma_wmb() barrier is added to update the
long term buffer before it being accessed by VIOS (virtual i/o server).

From: Lijun Pan <ljp@linux.ibm.com>

[ Upstream commit 7d3a7b9ea59ddb223aec59b45fa1713c633aaed4 ]

Timeout reset will trigger the VIOS to unmap it automatically,
similarly as FAILVOER and MOBILITY events. If we unmap it
in the linux side, we will see errors like
"30000003: Error 4 in REQUEST_UNMAP_RSP".
So, don't call send_request_unmap for timeout reset.

[ Upstream commit 30b7edc82ec82578f4f5e6706766f0a9535617d3 ]

Sometimes mailbox commands timeout when the RX data path becomes
unresponsive. This prevents the submission of new mailbox commands to DXIO.
This patch identifies the timeout and resets the RX data path so that the
next message can be submitted properly.

[ Upstream commit 186edbb510bd60e748f93975989ccba25ee99c50 ]

The current driver calls netif_carrier_off() late in the link tear down
which can result in a netdev watchdog timeout.

Calling netif_carrier_off() immediately after netif_tx_stop_all_queues()
avoids the warning.

[ Upstream commit 84fe68eb67f9499309cffd97c1ba269de125ff14 ]

Normally, auto negotiation and reconnect should be automatically done by
the hardware. But there seems to be an issue where auto negotiation has
to be restarted manually. This happens because of link training and so
even though still connected to the partner the link never "comes back".
This needs an auto-negotiation restart.

Also, a change in xgbe-mdio is needed to get ethtool to recognize the
link down and get the link change message. This change is only
required in a backplane connection mode.

According to Errata #23 "The per-CPU GbE interrupt is limited to Core
0", we can't use the per-cpu interrupt mechanism on the Armada 3700

This is correctly checked for RSS configuration, but the initial queue
mapping is still done by having the queues spread across all the CPUs in
the system, both in the init path and in the cpu_hotplug path.

From: Randy Dunlap <rdunlap@infradead.org>

[ Upstream commit c6c90c70db4d9a0989111d6b994d545659410f7a ]

It looks like SPARC64 requires FB_ATY_CT to build without errors,
so have FB_ATY select FB_ATY_CT if both SPARC64 and PCI are enabled
instead of using "default y if SPARC64 && PCI", which is not strong
enough to prevent build errors.

As it currently is, FB_ATY_CT can be disabled, resulting in build
errors:

ERROR: modpost: "aty_postdividers" [drivers/video/fbdev/aty/atyfb.ko] undefined!
ERROR: modpost: "aty_ld_pll_ct" [drivers/video/fbdev/aty/atyfb.ko] undefined!

[ Upstream commit 15ccc39b3aab667c6fa131206f01f31bfbccdf6a ]

The main problem with this error handling was that it didn't clean up if
i2c_add_numbered_adapter() failed.  This code is pretty old, and doesn't
match with today's checkpatch.pl standards so I took the opportunity to
tidy it up a bit.  I changed the NULL comparison, and removed the
WARNING message if kzalloc() fails and updated the label names.

From: Corentin Labbe <clabbe@baylibre.com>

[ Upstream commit 9bc3dd24e7dccd50757db743a3635ad5b0497e6e ]

With the recent kmap change, some tests which were conditional on
CONFIG_DEBUG_HIGHMEM now are enabled by default.
This permit to detect a problem in sun4i-ss usage of kmap.

sun4i-ss uses two kmap via sg_miter (one for input, one for output), but
using two kmap at the same time is hard:
"the ordering has to be correct and with sg_miter that's probably hard to get
right." (quoting Tlgx)

So the easiest solution is to never have two sg_miter/kmap open at the same time.
After each use of sg_miter, I store the current index, for being able to
resume sg_miter to the right place.

reference from the function r4k_cache_init() to the function

From: Jacopo Mondi <jacopo@jmondi.org>

[ Upstream commit dc1eb7c9c290cba52937c9a224b22a400bb0ffd7 ]

The driver currently reports a single supported value for
V4L2_CID_PIXEL_RATE and initializes the control's minimum value to 0,
which is very risky, as userspace might accidentally use it as divider
when calculating the time duration of a line.

Fix this by using as minimum the only supported value when registering
the control.

When kzalloc() fails, em28xx_uninit_usb_xfer() will free
usb_bufs->buf and set it to NULL. Thus the later access
to usb_bufs->buf[i] will lead to null pointer dereference.
Also the kfree(usb_bufs->buf) after that is redundant.

Renaming 'struct device_private' to 'struct bcm_device_private',
because it clashes with 'struct device_private' from
'drivers/base/base.h'.

While it's not a functional problem, it's causing two distinct
type hierarchies in BTF data. It also breaks build with options:

[ Upstream commit 1916866dfa4aaceba1a70db83fde569387649d93 ]

In set_clamp(), the comments and definitions for the COLOR_DEPTH_101010
and COLOR_DEPTH_121212 cases directly contradict the code comment which
explains how this should work, whereas the COLOR_DEPTH_888 case
is consistent with the code comments. Comment says the bitmask should
be chosen to align to the top-most 10 or 12 MSB's on a 14 bit bus, but
the implementation contradicts that: 10 bit case sets a mask for 12 bpc
clamping, whereas 12 bit case sets a mask for 14 bpc clamping.

Note that during my limited testing on DCE-8.3 (HDMI deep color)
and DCE-11.2 (DP deep color), this didn't have any obvious ill
effects, neither did fixing it change anything obvious for the
better, so this fix may be inconsequential on DCE, and just
reduce the confusion of innocent bystanders when reading the code
and trying to investigate problems with 10 bpc+ output.

single statement.

Replace the comma with a semicolon.

reallocated with the bigger 'size'.

[ Upstream commit dc9455ffae02d7b7fb51ba1e007fffcb9dc5d890 ]

The Renkforce RF AC4K 300 Action Cam 4K reports invalid bFormatIndex and
bFrameIndex values when negotiating the video probe and commit controls.
The UVC descriptors report a single supported format and frame size,
with bFormatIndex and bFrameIndex both equal to 2, but the video probe
and commit controls report bFormatIndex and bFrameIndex set to 1.

The device otherwise operates correctly, but the driver rejects the
values and fails the format try operation. Fix it by ignoring the
invalid indices, and assuming that the format and frame requested by the
driver are accepted by the device.

[ Upstream commit 416b846757bcea20006a9197e67ba3a8b5b2a680 ]

Talitos Security Engine AESU considers any input
data size that is not a multiple of 16 bytes to be an error.
This is not a problem in general, except for Counter mode
that is a stream cipher and can have an input of any size.

Test Manager for ctr(aes) fails on 4th test vector which has
a length of 499 while all previous vectors which have a 16 bytes
multiple length succeed.

As suggested by Freescale, round up the input data length to the
nearest 16 bytes.

[ Upstream commit 10340f8d7b6dd54e616339c8ccb2f397133ebea0 ]

While reworking the resources management and departing from using
ahci_platform_enable_resources() which did not allow a proper step
separation like we need, we unfortunately lost the ability to control
AHCI regulators. This broke some Broadcom STB systems that do expect
regulators to be turned on to link up with attached hard drives.

[ Upstream commit de5bfae2fd962a9da99f56382305ec7966a604b9 ]

The correct mask is 0x1f8 (Bit 3-8), but due to missing BIT() 0xf (Bit
0-3) was set instead. This means setting of CPCAP_BIT_MIC1_RX_TIMESLOT0
(Bit 3) still worked (part of both masks). On the other hand the code
does not properly clear the other MIC timeslot bits. I think this
is not a problem, since they are probably initialized to 0 and not
touched by the driver anywhere else. But the mask also contains some
wrong bits, that will be cleared. Bit 0 (CPCAP_BIT_SMB_CDC) should be
safe, since the driver enforces it to be 0 anyways.

Bit 1-2 are CPCAP_BIT_FS_INV and CPCAP_BIT_CLK_INV. This means enabling
audio recording forces the codec into SND_SOC_DAIFMT_NB_NF mode, which
is obviously bad.

The bug probably remained undetected, because there are not many use
cases for routing microphone to the CPU on platforms using cpcap and
user base is small. I do remember having some issues with bad sound
quality when testing voice recording back when I wrote the driver.
It probably was this bug.

The root cause is:
If we open file w/ readonly flag, disk quota info won't be initialized
for this file, however, following mmap() will force to convert inline
inode via f2fs_convert_inline_inode(), which may increase block usage
for this inode w/o updating quota data, it causes inconsistent disk quota
info.

The issue will happen in following stack:
open(file, O_RDONLY)
mmap(file)
- f2fs_convert_inline_inode
 - f2fs_convert_inline_page
  - f2fs_reserve_block
   - f2fs_reserve_new_block
    - f2fs_reserve_new_blocks
     - f2fs_i_blocks_write
      - dquot_claim_block
inode->i_blocks increase, but the dqb_curspace keep the size for the dquots
is NULL.

To fix this issue, let's call dquot_initialize() anyway in both
f2fs_truncate() and f2fs_convert_inline_inode() functions to avoid potential
inconsistent quota data issue.

From: Andrea Parri (Microsoft) <parri.andrea@gmail.com>

[ Upstream commit e3fa4b747f085d2cda09bba0533b86fa76038635 ]

When channel->device_obj is non-NULL, vmbus_onoffer_rescind() could
invoke put_device(), that will eventually release the device and free
the channel object (cf. vmbus_device_release()).  However, a pointer
to the object is dereferenced again later to load the primary_channel.
The use-after-free can be avoided by noticing that this load/check is
redundant if device_obj is non-NULL: primary_channel must be NULL if
device_obj is non-NULL, cf. vmbus_add_channel_work().

[ Upstream commit 3cc64e7ebfb0d7faaba2438334c43466955a96e8 ]

Return value in __load_free_space_cache is not properly set after
(unlikely) memory allocation failures and 0 is returned instead.
This is not a problem for the caller load_free_space_cache because only
value 1 is considered as 'cache loaded' but for clarity it's better
to set the errors accordingly.

[ Upstream commit 19646447ad3a680d2ab08c097585b7d96a66126b ]

clang static analysis reports this problem

fs/jffs2/summary.c:794:31: warning: Use of memory after it is freed
                c->summary->sum_list_head = temp->u.next;
                                            ^~~~~~~~~~~~

In jffs2_sum_write_data(), in a loop summary data is handles a node at
a time.  When it has written out the node it is removed the summary list,
and the node is deleted.  In the corner case when a
JFFS2_FEATURE_RWCOMPAT_COPY is seen, a call is made to
jffs2_sum_disable_collecting().  jffs2_sum_disable_collecting() deletes
the whole list which conflicts with the loop's deleting the list by parts.

To preserve the old behavior of stopping the write midway, bail out of
the loop after disabling summary collection.

[ Upstream commit 95ebabde382c371572297915b104e55403674e73 ]

The v3 file capabilities have a uid field that records the filesystem
uid of the root user of the user namespace the file capabilities are
valid in.

When someone is silly enough to have the same underlying uid as the
root uid of multiple nested containers a v3 filesystem capability can
be ambiguous.

In the spirit of don't do that then, forbid writing a v3 filesystem
capability if it is ambiguous.

[ Upstream commit ceeda328edeeeeac7579e9dbf0610785a3b83d39 ]

The controller can only support up to 31 dummy cycles. If the command
requires more it falls back to using 31. This command is likely to fail
because the correct number of cycles are not waited upon. Rather than
silently issuing an incorrect command, fail loudly so the caller can get
a chance to find out the command can't be supported by the controller.

The CEC clock on the H6 SoC is a bit special, since it uses a fixed
pre-dividier for one source clock (the PLL), but conveys the other clock
(32K OSC) directly.
We are using a fixed predivider array for that, but fail to use the right
flag to actually activate that.

[ Upstream commit a0312af1f94d13800e63a7d0a66e563582e39aec ]

Prevent invalid (0, 0) inputs to hid-core's snto32() function.

Maybe it is just the dummy device here that is causing this, but
there are hundreds of calls to snto32(0, 0). Having n (bits count)
of 0 is causing the current UBSAN trap with a shift value of
0xffffffff (-1, or n - 1 in this function).

Either of the value to shift being 0 or the bits count being 0 can be
handled by just returning 0 to the caller, avoiding the following
complex shift + OR operations:

	return value & (1 << (n - 1)) ? value | (~0U << n) : value;

[ Upstream commit 035b73b2b3b2e074a56489a7bf84b6a8012c0e0d ]

On Intel Tangier B0 and Anniedale the interrupt line, disregarding
to have different numbers, is shared between HSU DMA and UART IPs.
Thus on such SoCs we are expecting that IRQ handler is called in
UART driver only. hsu_pci_irq was handling the spurious interrupt
from HSU DMA by returning immediately. This wastes CPU time and
since HSU DMA and HSU UART interrupt occur simultaneously they race
to be handled causing delay to the HSU UART interrupt handling.
Fix this by disabling the interrupt entirely.

From: Nicolas Boichat <drinkcat@chromium.org>

[ Upstream commit 8a5a75e5e9e55de1cef5d83ca3589cb4899193ef ]

If the device tree is incorrectly configured, and attempts to
define a "no-map" reserved memory that overlaps with the kernel
data/code, the kernel would crash quickly after boot, with no
obvious clue about the nature of the issue.

For example, this would happen if we have the kernel mapped at
these addresses (from /proc/iomem):
40000000-41ffffff : System RAM
  40080000-40dfffff : Kernel code
  40e00000-411fffff : reserved
  41200000-413e0fff : Kernel data

And we declare a no-map shared-dma-pool region at a fixed address
within that range:
mem_reserved: mem_region {
	compatible = "shared-dma-pool";
	reg = <0 0x40000000 0 0x01A00000>;
	no-map;
};

To fix this, when removing memory regions at early boot (which is
what "no-map" regions do), we need to make sure that the memory
is not already reserved. If we do, __reserved_mem_reserve_reg
will throw an error:
[    0.000000] OF: fdt: Reserved memory: failed to reserve memory
   for node 'mem_region': base 0x0000000040000000, size 26 MiB
and the code that will try to use the region should also fail,
later on.

We do not do anything for non-"no-map" regions, as memblock
explicitly allows reserved regions to overlap, and the commit
that this fixes removed the check for that precise reason.

The rtc-s5m uses the I2C regmap but doesn't select it in Kconfig so
depending on the configuration the build may fail. Fix it.

[ Upstream commit 04ef679591c76571a9e7d5ca48316cc86fa0ef12 ]

While comparing clocks between the H6 and H616, some of the M factor
ranges were found to be wrong: the manual says they are only covering
two bits [1:0], but our code had "5" in the number-of-bits field.

By writing 0xff into that register in U-Boot and via FEL, it could be
confirmed that bits [4:2] are indeed masked off, so the manual is right.

Change to number of bits in the affected clock's description.

From: David Howells <dhowells@redhat.com>

[ Upstream commit 4993e1f9479a4161fd7d93e2b8b30b438f00cb0f ]

KEY_FLAG_KEEP is not meant to be passed to keyring_alloc() or key_alloc(),
as these only take KEY_ALLOC_* flags.  KEY_FLAG_KEEP has the same value as
KEY_ALLOC_BYPASS_RESTRICTION, but fortunately only key_create_or_update()
uses it.  LSMs using the key_alloc hook don't check that flag.

KEY_FLAG_KEEP is then ignored but fortunately (again) the root user cannot
write to the blacklist keyring, so it is not possible to remove a key/hash
from it.

Fix this by adding a KEY_ALLOC_SET_KEEP flag that tells key_alloc() to set
KEY_FLAG_KEEP on the new key.  blacklist_init() can then, correctly, pass
this to keyring_alloc().

We can also use this in ima_mok_init() rather than setting the flag
manually.

Note that this doesn't fix an observable bug with the current
implementation but it is required to allow addition of new hashes to the
blacklist in the future without making it possible for them to be removed.

MAD message received by the user has EINVAL error in all flows
including when the device is disassociated. That makes it impossible
for the applications to treat such flow differently.

Change it to return EIO, so the applications will be able to perform
disassociation recovery.

Currently, polling a umad device will always works, even if the device was
disassociated. A disassociated device should immediately return EPOLLERR
from poll(). Otherwise userspace is endlessly hung on poll() with no idea
that the device has been removed from the system.

[ Upstream commit 910a0cb6d259736a0c86e795d4c2f42af8d0d775 ]

PPC47x_TLBE_SIZE isn't defined for 256k pages, leading to a build
break if 256k pages is selected.

So change the kconfig so that 256k pages can't be selected for 47x.

From: Vladimir Murzin <vladimir.murzin@arm.com>

[ Upstream commit 2acb909750431030b65a0a2a17fd8afcbd813a84 ]

It was observed that decompressor running on hardware implementing ARM v8.2
Load/Store Multiple Atomicity and Ordering Control (LSMAOC), say, as guest,
would stuck just after:

Uncompressing Linux... done, booting the kernel.

The reason is that it clears nTLSMD bit when disabling caches:

  nTLSMD, bit [3]

  When ARMv8.2-LSMAOC is implemented:

    No Trap Load Multiple and Store Multiple to
    Device-nGRE/Device-nGnRE/Device-nGnRnE memory.

    0b0 All memory accesses by A32 and T32 Load Multiple and Store
        Multiple at EL1 or EL0 that are marked at stage 1 as
        Device-nGRE/Device-nGnRE/Device-nGnRnE memory are trapped and
        generate a stage 1 Alignment fault.

    0b1 All memory accesses by A32 and T32 Load Multiple and Store
        Multiple at EL1 or EL0 that are marked at stage 1 as
        Device-nGRE/Device-nGnRE/Device-nGnRnE memory are not trapped.

  This bit is permitted to be cached in a TLB.

  This field resets to 1.

  Otherwise:

  Reserved, RES1

So as effect we start getting traps we are not quite ready for.

Looking into history it seems that mask used for SCTLR clear came from
the similar code for ARMv4, where bit[3] is the enable/disable bit for
the write buffer. That not applicable to ARMv7 and onwards, so retire
that bit from the masks.

[ Upstream commit de5d7adb89367bbc87b4e5ce7afe7ae9bd86dc12 ]

Consider an amba driver with a .probe but without a .remove callback (e.g.
pl061_gpio_driver). The function amba_probe() is called to bind a device
and so dev_pm_domain_attach() and others are called. As there is no remove
callback amba_remove() isn't called at unbind time however and so calling
dev_pm_domain_detach() is missed and the pm domain keeps active.

To fix this always use the core driver callbacks and handle missing amba
callbacks there. For probe refuse registration as a driver without probe
doesn't make sense.

[ Upstream commit befe6d946551d65cddbd32b9cb0170b0249fd5ed ]

The list of tracepoint callbacks is managed by an array that is protected
by RCU. To update this array, a new array is allocated, the updates are
copied over to the new array, and then the list of functions for the
tracepoint is switched over to the new array. After a completion of an RCU
grace period, the old array is freed.

This process happens for both adding a callback as well as removing one.
But on removing a callback, if the new array fails to be allocated, the
callback is not removed, and may be used after it is freed by the clients
of the tracepoint.

There's really no reason to fail if the allocation for a new array fails
when removing a function. Instead, the function can simply be replaced by a
stub function that could be cleaned up on the next modification of the
array. That is, instead of calling the function registered to the
tracepoint, it would call a stub function in its place.

Link: https://lkml.kernel.org/r/20201118093405.7a6d2290@gandalf.local.home

[ Note, this version does use undefined compiler behavior (assuming that
  a stub function with no parameters or return, can be called by a location
  that thinks it has parameters but still no return value. Static calls
  do the same thing, so this trick is not without precedent.

  There's another solution that uses RCU tricks and is more complex, but
  can be an alternative if this solution becomes an issue.

[ Upstream commit c69bf11ad3d30b6bf01cfa538ddff1a59467c734 ]

When we lookup an address and don't find a map we should filter that
sample if the user specified a list of --dso entries to filter on, fix
it.

Before:

  $ perf script
             sleep 274800  2843.556162:          1 cycles:u:  ffffffffbb26bff4 [unknown] ([unknown])
             sleep 274800  2843.556168:          1 cycles:u:  ffffffffbb2b047d [unknown] ([unknown])
             sleep 274800  2843.556171:          1 cycles:u:  ffffffffbb2706b2 [unknown] ([unknown])
             sleep 274800  2843.556174:          6 cycles:u:  ffffffffbb2b0267 [unknown] ([unknown])
             sleep 274800  2843.556176:         59 cycles:u:  ffffffffbb2b03b1 [unknown] ([unknown])
             sleep 274800  2843.556180:        691 cycles:u:  ffffffffbb26bff4 [unknown] ([unknown])
             sleep 274800  2843.556189:       9160 cycles:u:      7fa9550eeaa3 __GI___tunables_init+0xf3 (/usr/lib64/ld-2.32.so)
             sleep 274800  2843.556312:      86937 cycles:u:      7fa9550e157b _dl_lookup_symbol_x+0x4b (/usr/lib64/ld-2.32.so)
  $

So we have some samples we somehow didn't find in a map for, if we now
do:

  $ perf report --stdio --dso /usr/lib64/ld-2.32.so
  # dso: /usr/lib64/ld-2.32.so
  #
  # Total Lost Samples: 0
  #
  # Samples: 8  of event 'cycles:u'
  # Event count (approx.): 96856
  #
  # Overhead  Command  Symbol
  # ........  .......  ........................
  #
      89.76%  sleep    [.] _dl_lookup_symbol_x
       9.46%  sleep    [.] __GI___tunables_init
       0.71%  sleep    [k] 0xffffffffbb26bff4
       0.06%  sleep    [k] 0xffffffffbb2b03b1
       0.01%  sleep    [k] 0xffffffffbb2b0267
       0.00%  sleep    [k] 0xffffffffbb2706b2
       0.00%  sleep    [k] 0xffffffffbb2b047d
  $

After this patch we get the right output with just entries for the DSOs
specified in --dso:

  $ perf report --stdio --dso /usr/lib64/ld-2.32.so
  # dso: /usr/lib64/ld-2.32.so
  #
  # Total Lost Samples: 0
  #
  # Samples: 8  of event 'cycles:u'
  # Event count (approx.): 96856
  #
  # Overhead  Command  Symbol
  # ........  .......  ........................
  #
      89.76%  sleep    [.] _dl_lookup_symbol_x
       9.46%  sleep    [.] __GI___tunables_init
  $
  #

[ Upstream commit 7d9ae80e31df57dd3253e1ec514f0000aa588a81 ]

check_type_state() in rxe_recv.c is written as if the type bits in the
packet opcode were a bit mask which is not correct. This patch corrects
this code to compare all 3 type bits to the required type.

[ Upstream commit 5120bf0a5fc15dec210a0fe0f39e4a256bb6e349 ]

rxe_net.c sends packets at the IP layer with skb->data pointing at the IP
header but receives packets from a UDP tunnel with skb->data pointing at
the UDP header.  On the loopback path this was not correctly accounted
for.  This patch corrects for this by using sbk_pull() to strip the IP
header from the skb on received packets.

1. When the status is -2 (busy, call again), we call
   ibm,configure-connector again immediately without checking whether
   to schedule, which can result in monopolizing the CPU.
2. Extended delay status (9900..9905) goes completely unhandled,
   causing the configuration to unnecessarily terminate.

Fix both of these issues by using rtas_busy_delay().

[ Upstream commit 903178d0ce6bb30ef80a3604ab9ee2b57869fbc9 ]

For unimplemented instructions or unimplemented SPRs, the 8xx triggers
a "Software Emulation Exception" (0x1000). That interrupt doesn't set
reason bits in SRR1 as the "Program Check Exception" does.

Go through emulation_assist_interrupt() to set REASON_ILLEGAL.

[ Upstream commit 292f75ecff07e8a07fe2e3e19b4b567d0b698842 ]

All of the GPLLs in the MSM8998 Global Clock Controller are Fabia PLLs
and not generic alphas: this was producing bad effects over the entire
clock tree of MSM8998, where any GPLL child clock was declaring a false
clock rate, due to their parent also showing the same.

The issue resides in the calculation of the clock rate for the specific
Alpha PLL type, where Fabia has a different register layout; switching
the MSM8998 GPLLs to the correct Alpha Fabia PLL type fixes the rate
(calculation) reading. While at it, also make these PLLs fixed since
their rate is supposed to *never* be changed while the system runs, as
this would surely crash the entire SoC.

Now all the children of all the PLLs are also complying with their
specified clock table and system stability is improved.

[ Upstream commit 54c5d3bfb0cfb7b31259765524567871dee11615 ]

Wildcat Point has two SPI controllers and added one is actually second one.
Fix the numbering by adding the description of the first one.

The ubsan reported the following error.  It was because sample's raw
data missed u32 padding at the end.  So it broke the alignment of the
array after it.

The raw data contains an u32 size prefix so the data size should have
an u32 padding after 8-byte aligned data.

Currently COMPAT on SPARC64 selects COMPAT_BINFMT_ELF unconditionally,
even when BINFMT_ELF is not enabled. This causes a kconfig warning.

Instead, just select COMPAT_BINFMT_ELF if BINFMT_ELF is enabled.
This builds cleanly with no kconfig warnings.

[ Upstream commit 4540b9fbd8ebb21bb3735796d300a1589ee5fbf2 ]

Module alias "spi:93xx46" is used by non device tree users like
drivers/misc/eeprom/digsy_mtc_eeprom.c  and removing it will
break support for them.

Fix this by adding back the module alias "spi:93xx46".

[ Upstream commit d5d8d675865ccddfe4da26c85f22c55cec663bf2 ]

If rockchip_pwm_probe() fails to register a PWM device it calls
clk_unprepare() for the device's PWM clock, without having first disabled
the clock and before jumping to an error handler that also unprepares
it. This is likely to produce warnings from the kernel about the clock
being unprepared when it is still enabled, and then being unprepared when
it has already been unprepared.

Prevent these warnings by removing this unnecessary call to
clk_unprepare().

When the VMCI host support releases guest memory in the case where
the VM was killed, the pinned guest pages aren't locked. Use
set_page_dirty_lock() instead of set_page_dirty().

Testing done: Killed VM while having an active VMCI based vSocket
connection and observed warning from ext4. With this fix, no
warning was observed. Ran various vSocket tests without issues.

[ Upstream commit ef9e4005cbaf022c6251263aa27836acccaef65d ]

After 34e3207205ef ("PCI: handle positive error codes"),
pci_user_read_config_*() and pci_user_write_config_*() return 0 or negative
errno values, not PCIBIOS_* values like PCIBIOS_SUCCESSFUL or
PCIBIOS_BAD_REGISTER_NUMBER.

Remove comparisons with PCIBIOS_SUCCESSFUL and check only for non-zero.  It
happens that PCIBIOS_SUCCESSFUL is zero, so this is not a functional
change, but it aligns this code with the user accessors.

[ Upstream commit b5776e7524afbd4569978ff790864755c438bba7 ]

In the case where we need to do an interior node split, and
immediately afterwards, we are unable to allocate a new directory leaf
block due to ENOSPC, the directory index checksum's will not be filled
in correctly (and indeed, will not be correctly journalled).

This looks like a bug that was introduced when we added largedir
support.  The original code doesn't make any sense (and should have
been caught in code review), but it was hidden because most of the
time, the index node checksum will be set by do_split().  But if
do_split bails out due to ENOSPC, then ext4_handle_dirty_dx_node()
won't get called, and so the directory index checksum field will not
get set, leading to:

EXT4-fs error (device sdb): dx_probe:858: inode #6635543: block 4022: comm nfsd: Directory index failed checksum

[ Upstream commit d288a5712ef961e16d588bbdb2d846e00b5ef154 ]

sdw_update_slave_status will be invoked when a codec is attached,
and the codec driver will initialize the codec with regmap functions
while the codec device is pm_runtime suspended.

regmap routines currently rely on regular SoundWire IO functions,
which will call pm_runtime_get_sync()/put_autosuspend.

This causes a deadlock where the resume routine waits for an
initialization complete signal that while the initialization complete
can only be reached when the resume completes.

The only solution if we allow regmap functions to be used in resume
operations as well as during codec initialization is to use _no_pm
routines. The duty of making sure the bus is operational needs to be
handled above the regmap level.

[ Upstream commit 92c6058024e87087cf1b99b0389d67c0a886360e ]

When a packet contains an IPv6 header with next header which is
an extension header and not a protocol one, the kernel function
skb_transport_header called with such sk_buff will return a
pointer to the extension header and not to the TCP one.

The above explained call caused a problem with packet processing
for skb with encapsulation for tunnel with I40E_TX_CTX_EXT_IP_IPV6.
The extension header was not skipped at all.

The ipv6_skip_exthdr function does check if next header of the IPV6
header is an extension header and doesn't modify the l4_proto pointer
if it points to a protocol header value so its safe to omit the
comparison of exthdr and l4.hdr pointers. The ipv6_skip_exthdr can
return value -1. This means that the skipping process failed
and there is something wrong with the packet so it will be dropped.

During driver loading flow control settings were written to FW
using a variable which was always zero, since it was being set
only by ethtool. This behavior has been corrected and driver
no longer overwrites the default FW/NVM settings.

[ Upstream commit dc8812626440fa6a27f1f3f654f6dc435e042e42 ]

When creating VFs they were sometimes not getting resources.
It was caused by not executing i40e_reset_all_vfs due to
flag __I40E_VF_DISABLE being set on PF. Because of this
IAVF was never able to finish setup sequence never
getting reset indication from PF.
Changed test_and_set_bit __I40E_VF_DISABLE in
i40e_sync_filters_subtask to test_bit and removed clear_bit.
This function should not set this bit it should only check
if it hasn't been already set.

can lead to use-after-free accesses to freed VMAs.

[ Upstream commit 8eb65fda4a6dbd59cd5de24b106a10b6ee0d2176 ]

mlx4_do_mirror_rule() forgets to call mlx4_free_cmd_mailbox() to
free the memory region allocated by mlx4_alloc_cmd_mailbox() before
an exit.
Add the missed call to fix it.

[ Upstream commit 92584ddf550ae72d492858c19d1f9025e07a9350 ]

The debug check must be done after unregister_netdevice_many() call --
the hlist_del_rcu() for this is done inside .ndo_stop.

This is the same with commit 0fda7600c2e1 ("geneve: move debug check after
netdev unregister")

Test commands:
    ip netns del A
    ip netns add A
    ip netns add B

    ip netns exec B ip link add vxlan0 type vxlan vni 100 local 10.0.0.1 \
	    remote 10.0.0.2 dstport 4789 srcport 4789 4789
    ip netns exec B ip link set vxlan0 netns A
    ip netns exec A ip link set vxlan0 up
    ip netns del B

Splat looks like:

[ Upstream commit c57d117f2b2f2a19b570c36f2819ef8d8210af20 ]

The error handling in this function frees "reg" but it is still on the
"o2hb_all_regions" list so it will lead to a use after freew.  Joseph Qi
points out that we need to clear the bit in the "o2hb_region_bitmap" as
well

[ Upstream commit 90a3e375d324b2255b83e3dd29e99e2b05d82aaf ]

Since commit 42e4089c7890 ("x86/speculation/l1tf: Disallow non privileged
high MMIO PROT_NONE mappings"), when the first pfn modify is not allowed,
we would break the loop with pte unchanged.  Then the wrong pte - 1 would
be passed to pte_unmap_unlock.

Andi said:

 "While the fix is correct, I'm not sure if it actually is a real bug.
  Is there any architecture that would do something else than unlocking
  the underlying page? If it's just the underlying page then it should
  be always the same page, so no bug"

In hugetlb_sysfs_add_hstate(), we would do kobject_put() on hstate_kobjs
when failed to create sysfs group but forget to set hstate_kobjs to NULL.
Then in hugetlb_register_node() error path, we may free it again via
hugetlb_unregister_node().

Aligning the values for register MaxTxPacketSize with the
vendor driver fixes the problem.

[ Upstream commit 9d41053e8dc115c92b8002c3db5f545d7602498b ]

Although there has been a bit of back and forth on the subject, it
appears that invalidating TLBs requires an ISB instruction when FEAT_ETS
is not implemented by the CPU.

>From the bible:

  | In an implementation that does not implement FEAT_ETS, a TLB
  | maintenance instruction executed by a PE, PEx, can complete at any
  | time after it is issued, but is only guaranteed to be finished for a
  | PE, PEx, after the execution of DSB by the PEx followed by a Context
  | synchronization event

Add the missing ISB in __primary_switch, just in case.

The brcmstb_send_i2c_cmd currently has a condition that is (CMD_RD ||
CMD_WR) which always evaluates to true, while the obvious fix is to test
whether the cmd variable passed as parameter holds one of these two
values.

[ Upstream commit 5d5d19eda6b0ee790af89c45e3f678345be6f50f ]

For PMD-mapped page (usually THP), pvmw->pte is NULL.  For PTE-mapped THP,
pvmw->pte is mapped.  But for HugeTLB pages, pvmw->pte is not mapped and
set to the relevant page table entry.  So in page_vma_mapped_walk_done(),
we may do pte_unmap() for HugeTLB pte which is not mapped.  Fix this by
checking pvmw->page against PageHuge before trying to do pte_unmap().

From: Mikulas Patocka <mpatocka@redhat.com>

commit 97f433c3601a24d3513d06f575a389a2ca4e11e4 upstream.

We get I/O errors when we run md-raid1 on the top of dm-integrity on the
top of ramdisk.
device-mapper: integrity: Bio not aligned on 8 sectors: 0xff00, 0xff
device-mapper: integrity: Bio not aligned on 8 sectors: 0xff00, 0xff
device-mapper: integrity: Bio not aligned on 8 sectors: 0xffff, 0x1
device-mapper: integrity: Bio not aligned on 8 sectors: 0xffff, 0x1
device-mapper: integrity: Bio not aligned on 8 sectors: 0x8048, 0xff
device-mapper: integrity: Bio not aligned on 8 sectors: 0x8147, 0xff
device-mapper: integrity: Bio not aligned on 8 sectors: 0x8246, 0xff
device-mapper: integrity: Bio not aligned on 8 sectors: 0x8345, 0xbb

The ramdisk device has logical_block_size 512 and max_sectors 255. The
dm-integrity device uses logical_block_size 4096 and it doesn't affect the
"max_sectors" value - thus, it inherits 255 from the ramdisk. So, we have
a device with max_sectors not aligned on logical_block_size.

The md-raid device sees that the underlying leg has max_sectors 255 and it
will split the bios on 255-sector boundary, making the bios unaligned on
logical_block_size.

In order to fix the bug, we round down max_sectors to logical_block_size.

From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

commit e1e6bd2995ac0e1ad0c2a2d906a06f59ce2ed293 upstream.

Property matching does not work for ACPI fwnodes if the value of the
given property is not represented as a package in the _DSD package
containing it.  For example, the "compatible" property in the _DSD
below

  Name (_DSD, Package () {
    ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
    Package () {
      Package () {"compatible", "ethernet-phy-ieee802.3-c45"}
    }
  })

will not be found by fwnode_property_match_string(), because the ACPI
code handling device properties does not regard the single value as a
"list" in that case.

Namely, fwnode_property_match_string() invoked to match a given
string property value first calls fwnode_property_read_string_array()
with the last two arguments equal to NULL and 0, respectively, in
order to count the items in the value of the given property, with the
assumption that this value may be an array.  For ACPI fwnodes, that
operation is carried out by acpi_node_prop_read() which calls
acpi_data_prop_read() for this purpose.  However, when the return
(val) pointer is NULL, that function only looks for a property whose
value is a package without checking the single-value case at all.

To fix that, make acpi_data_prop_read() check the single-value
case if its return pointer argument is NULL and modify
acpi_data_prop_read_single() handling that case to attempt to
read the value of the property if the return pointer is NULL
and return 1 if that succeeds.

commit 67e40054de86aae520ddc2a072d7f6951812a14f upstream.

A list_add corruption is reported by Hulk Robot like this:
==============
list_add corruption.
Call Trace:

It's because of the missing check after configfs_register_default_group,
where configfs_unregister_subsystem should be called once failure.

From: Jason Gerecke <killertofu@gmail.com>

commit 88f38846bfb1a452a3d47e38aeab20a4ceb74294 upstream.

The `wacom_feature_mapping` function is careful to only set the the
touch_max value a single time, but this care does not extend to the
`wacom_wac_finger_event` function. In particular, if a device sends
multiple HID_DG_CONTACTMAX items in a single feature report, the
driver will end up retaining the value of last item.

The HID descriptor for the Cintiq Companion 2 does exactly this. It
incorrectly sets a "Report Count" of 2, which will cause the driver
to process two HID_DG_CONTACTCOUNT items. The first item has the actual
count, while the second item should have been declared as a constant
zero. The constant zero is the value the driver ends up using, however,
since it is the last HID_DG_CONTACTCOUNT in the report.

    Report ID (16),
    Usage (Contact Count Maximum),  ; Contact count maximum (55h, static value)
    Report Count (2),
    Logical Maximum (10),
    Feature (Variable),

To address this, we add a check that the touch_max is not already set
within the `wacom_wac_finger_event` function that processes the
HID_DG_TOUCHMAX item. We emit a warning if the value is set and ignore
the updated value.

This could potentially cause problems if there is a tablet which has
a similar issue but requires the last item to be used. This is unlikely,
however, since it would have to have a different non-zero value for
HID_DG_CONTACTMAX earlier in the same report, which makes no sense
except in the case of a firmware bug. Note that cases where the
HID_DG_CONTACTMAX items are in different reports is already handled
(and similarly ignored) by `wacom_feature_mapping` as mentioned above.

commit b5d6e7ab7fe7d186878142e9fc1a05e4c3b65eb9 upstream.

After commit 77b425399f6d ("Input: i8042 - use chassis info to skip
selftest on Asus laptops"), all modern Asus laptops have the i8042
selftest disabled. It has done by using chassys type "10" (laptop).

The Asus Zenbook Flip suffers from similar suspend/resume issues, but
it _sometimes_ work and sometimes it doesn't. Setting noselftest makes
it work reliably. In this case, we need to add chassis type "31"
(convertible) in order to avoid selftest in this device.

This patch prepares for qmi_wwan driver support for the device.
Previously "option" driver mapped itself to interfaces 0 and 3 (matching
ff/ff/ff), while interface 3 is in fact a QMI port.
Interfaces 1 and 2 (matching ff/00/00) expose AT commands,
and weren't supported previously at all.
Without this patch, a possible conflict would exist if device ID was
added to qmi_wwan driver for interface 3.

Update and simplify device ID to match interfaces 0-2 directly,
to expose QCDM (0), PCUI (1), and modem (2) ports and avoid conflict
with QMI (3), and ADB (4).

The modem is used inside ZTE MF283+ router and carriers identify it as
such.
Interface mapping is:
0: QCDM, 1: AT (PCUI), 2: AT (Modem), 3: QMI, 4: ADB

From: Paul Cercueil <paul@crapouillou.net>

commit 0eaa1a3714db34a59ce121de5733c3909c529463 upstream.

musb_queue_resume_work() would call the provided callback if the runtime
PM status was 'active'. Otherwise, it would enqueue the request if the
hardware was still suspended (musb->is_runtime_suspended is true).

This causes a race with the runtime PM handlers, as it is possible to be
in the case where the runtime PM status is not yet 'active', but the
hardware has been awaken (PM resume function has been called).

When hitting the race, the resume work was not enqueued, which probably
triggered other bugs further down the stack. For instance, a telnet
connection on Ingenic SoCs would result in a 50/50 chance of a
segmentation fault somewhere in the musb code.

Rework the code so that either we call the callback directly if
(musb->is_runtime_suspended == 0), or enqueue the query otherwise.

commit a1679af85b2ae35a2b78ad04c18bb069c37330cc upstream.

Valid range for DEPCFG.bInterval_m1 is from 0 to 13, and it must be set
to 0 when the controller operates in full-speed. See the programming
guide for DEPCFG command section 3.2.2.1 (v3.30a).

commit 4b049f55ed95cd889bcdb3034fd75e1f01852b38 upstream.

The dep->interval captures the number of frames/microframes per interval
from bInterval. Fullspeed interrupt endpoint bInterval is the number of
frames per interval and not 2^(bInterval - 1). So fix it here. This
change is only for debugging purpose and should not affect the interrupt
endpoint operation.

The most-significant bit of the sub-integer-prescaler index is set in
the high byte of the baudrate request wIndex also for FTX devices.

This fixes rates like 1152000 which got mapped to 1.2 MBd.

From: James Bottomley <James.Bottomley@HansenPartnership.com>

commit 3d9ae54af1d02a7c0edc55c77d7df2b921e58a87 upstream.

The TPM TIS specification says the TPM signals the acquisition of locality
when the TMP_ACCESS_REQUEST_USE bit goes to one *and* the
TPM_ACCESS_REQUEST_USE bit goes to zero.  Currently we only check the
former not the latter, so check both.  Adding the check on
TPM_ACCESS_REQUEST_USE should fix the case where the locality is
re-requested before the TPM has released it.  In this case the locality may
get released briefly before it is reacquired, which causes all sorts of
problems. However, with the added check, TPM_ACCESS_REQUEST_USE should
remain 1 until the second request for the locality is granted.

From: James Bottomley <James.Bottomley@HansenPartnership.com>

commit e42acf104d6e0bd7ccd2f09103d5be5e6d3c637c upstream.

The current release locality code seems to be based on the
misunderstanding that the TPM interrupts when a locality is released:
it doesn't, only when the locality is acquired.

Furthermore, there seems to be no point in waiting for the locality to
be released.  All it does is penalize the last TPM user.  However, if
there's no next TPM user, this is a pointless wait and if there is a
next TPM user, they'll pay the penalty waiting for the new locality
(or possibly not if it's the same as the old locality).

Fix the code by making release_locality as simple write to release
with no waiting for completion.

commit 8da7520c80468c48f981f0b81fc1be6599e3b0ad upstream.

Consider the following transcript:

$ keyctl add trusted kmk "new 32 blobauth=helloworld keyhandle=80000000 migratable=1" @u
add_key: Invalid argument

The documentation has the following description:

  migratable=   0|1 indicating permission to reseal to new PCR values,
                default 1 (resealing allowed)

The consequence is that "migratable=1" should succeed. Fix this by
allowing this condition to pass instead of return -EINVAL.

From: Josef Bacik <josef@toxicpanda.com>

commit 867ed321f90d06aaba84e2c91de51cd3038825ef upstream.

While testing my error handling patches, I added a error injection site
at btrfs_inc_extent_ref, to validate the error handling I added was
doing the correct thing.  However I hit a pretty ugly corruption while
doing this check, with the following error injection stack trace:

btrfs_inc_extent_ref
  btrfs_copy_root
    create_reloc_root
      btrfs_init_reloc_root
	btrfs_record_root_in_trans
	  btrfs_start_transaction
	    btrfs_update_inode
	      btrfs_update_time
		touch_atime
		  file_accessed
		    btrfs_file_mmap

This is because we do not catch the error from btrfs_inc_extent_ref,
which in practice would be ENOMEM, which means we lose the extent
references for a root that has already been allocated and inserted,
which is the problem.  Fix this by aborting the transaction if we fail
to do the reference modification.

From: Josef Bacik <josef@toxicpanda.com>

commit c78a10aebb275c38d0cfccae129a803fe622e305 upstream.

When recovering a relocation, if we run into a reloc root that has 0
refs we simply add it to the reloc_control->reloc_roots list, and then
clean it up later.  The problem with this is __del_reloc_root() doesn't
do anything if the root isn't in the radix tree, which in this case it
won't be because we never call __add_reloc_root() on the reloc_root.

This exit condition simply isn't correct really.  During normal
operation we can remove ourselves from the rb tree and then we're meant
to clean up later at merge_reloc_roots() time, and this happens
correctly.  During recovery we're depending on free_reloc_roots() to
drop our references, but we're short-circuiting.

Fix this by continuing to check if we're on the list and dropping
ourselves from the reloc_control root list and dropping our reference
appropriately.  Change the corresponding BUG_ON() to an ASSERT() that
does the correct thing if we aren't in the rb tree.

At btrfs_copy_root(), if the call to btrfs_inc_ref() fails we end up
returning without unlocking and releasing our reference on the extent

commit 0df07d8117c3576f1603b05b84089742a118d10a upstream.

The accelerated, instruction based implementations of SHA1, SHA2 and
SHA3 are autoloaded based on CPU capabilities, given that the code is
modest in size, and widely used, which means that resolving the algo
name, loading all compatible modules and picking the one with the
highest priority is taken to be suboptimal.

However, if these algorithms are requested before this CPU feature
based matching and autoloading occurs, these modules are not even
considered, and we end up with suboptimal performance.

So add the missing module aliases for the various SHA implementations.

From: Corentin Labbe <clabbe@baylibre.com>

commit 7bdcd851fa7eb66e8922aa7f6cba9e2f2427a7cf upstream.

The optimized cipher function need length multiple of 4 bytes.
But it get sometimes odd length.
This is due to SG data could be stored with an offset.

So the fix is to check also if the offset is aligned with 4 bytes.

commit b756f1c8fc9d84e3f546d7ffe056c5352f4aab05 upstream.

Allwinner A10 and A13 SoC have a version of the SS which produce
invalid IV in IVx register.

Instead of adding a variant for those, let's convert SS to produce IV
directly from data.

From: Jiri Bohac <jbohac@suse.cz>

commit 19d8e9149c27b689c6224f5c84b96a159342195a upstream.

Both pstore_compress() and decompress_record() use a mistyped config
option name ("PSTORE_COMPRESSION" instead of "PSTORE_COMPRESS"). As
a result compression and decompression of pstore records was always
disabled.

Use the correct config option name.

commit dc2e76175417e69c41d927dba75a966399f18354 upstream.

Fix extreme slow speed (200MB takes ~20 min) on writing sdcard on
bananapi-r64 by adding reset-control for mmc1 like it's done for mmc0/emmc.

From: Ilya Lipnitskiy <ilya.lipnitskiy@gmail.com>

commit 1f92798cbe7fe923479cff754dd06dd23d352e36 upstream.

Also use KBUILD_MODNAME for module name.

This driver is only used by RALINK MIPS MT7621 SoCs. Tested by building
against that target using OpenWrt with Linux 5.10.10.

Fixes the following error:
error: the following would cause module name conflict:
  drivers/dma/mediatek/mtk-hsdma.ko
  drivers/staging/mt7621-dma/mtk-hsdma.ko

From: Amey Narkhede <ameynarkhede03@gmail.com>

commit 7c3a0635cd008eaca9a734dc802709ee0b81cac5 upstream.

Stack allocated buffers cannot be used for DMA
on all architectures so allocate hci_packet buffer
using kmalloc.
