7be5c25e31 block: fix error unwinding in device_add_disk
[ Upstream commit 99d8690aae4b2f0d1d90075de355ac087f820a66 ]

One device_add is called disk->ev will be freed by disk_release, so we
should free it twice.  Fix this by allocating disk->ev after device_add
so that the extra local unwinding can be removed entirely.

Based on an earlier patch from Tetsuo Handa.

617339466f rtw88: Disable PCIe ASPM while doing NAPI poll on 8821CE
[ Upstream commit 24f5e38a13b5ae2b6105cda8bb47c19108e62a9a ]

Many Intel based platforms face system random freeze after commit
9e2fd29864c5 ("rtw88: add napi support").

The commit itself shouldn't be the culprit. My guess is that the 8821CE
only leaves ASPM L1 for a short period when IRQ is raised. Since IRQ is
masked during NAPI polling, the PCIe link stays at L1 and makes RX DMA
extremely slow. Eventually the RX ring becomes messed up:
[ 1133.194697] rtw_8821ce 0000:02:00.0: pci bus timeout, check dma status

Since the 8821CE hardware may fail to leave ASPM L1, manually do it in
the driver to resolve the issue.

b14e931c38 wilc1000: fix double free error in probe()
[ Upstream commit 4894edacfa93d7046bec4fc61fc402ac6a2ac9e8 ]

Smatch complains that there is a double free in probe:

drivers/net/wireless/microchip/wilc1000/spi.c:186 wilc_bus_probe() error: double free of 'spi_priv'
drivers/net/wireless/microchip/wilc1000/sdio.c:163 wilc_sdio_probe() error: double free of 'sdio_priv'

The problem is that wilc_netdev_cleanup() function frees "wilc->bus_data".
That's confusing and a layering violation.  Leave the frees in probe(),
delete the free in wilc_netdev_cleanup(), and add some new frees to the
remove() functions.

CN9130 has a built-in CP115 which has 2 GPIO controllers, but unlike in
Armada 7k and 8k both are left disabled by the SoC DTSI.

This first of all makes no sense as they are always present due to being
SoC built-in and its an issue as boards like CN9130-CRB use the CPO GPIO2
pins for regulators and SD card support without enabling them first.

So, enable both of them like Armada 7k and 8k do.

CN9130 has one CP115 built in, which like the CP110 has 2 GPIO and 2 SPI

However, unlike the Armada 7k and 8k the SoC DTSI doesn't add the required

So add the required aliases for GPIO and SPI controllers.

826501a17e ARM: 9159/1: decompressor: Avoid UNPREDICTABLE NOP encoding
[ Upstream commit a92882a4d270fbcc021ee6848de5e48b7f0d27f3 ]

In the decompressor's head.S we need to start with an instruction that
is some kind of NOP, but also mimics as the PE/COFF header, when the
kernel is linked as an UEFI application. The clever solution here is
"tstne r0, #0x4d000", which in the worst case just clobbers the
condition flags, and bears the magic "MZ" signature in the lowest 16 bits.

However the encoding used (0x13105a4d) is actually not valid, since bits
[15:12] are supposed to be 0 (written as "(0)" in the ARM ARM).
Violating this is UNPREDICTABLE, and *can* trigger an UNDEFINED
exception. Common Cortex cores seem to ignore those bits, but QEMU
chooses to trap, so the code goes fishing because of a missing exception
handler at this point. We are just saved by the fact that commonly (with
-kernel or when running from U-Boot) the "Z" bit is set, so the
instruction is never executed. See [0] for more details.

To make things more robust and avoid UNPREDICTABLE behaviour in the
kernel code, lets replace this with a "two-instruction NOP":
The first instruction is an exclusive OR, the effect of which the second
instruction reverts. This does not leave any trace, neither in a
register nor in the condition flags. Also it's a perfectly valid
encoding. Kudos to Peter Maydell for coming up with this gem.

As of commit 4782c0a5dd88 ("clk: tegra: Don't deassert reset on enabling
clocks"), module resets are no longer automatically deasserted when the
module clock is enabled. To make sure that the gr2d module continues to
work, we need to explicitly control the module reset.

307ac652e9 ath11k: Fix a NULL pointer dereference in ath11k_mac_op_hw_scan()
[ Upstream commit eccd25136386a04ebf46a64f3a34e8e0fab6d9e1 ]

In ath11k_mac_op_hw_scan(), the return value of kzalloc() is directly
used in memcpy(), which may lead to a NULL pointer dereference on
failure of kzalloc().

Fix this bug by adding a check of arg.extraie.ptr.

This bug was found by a static analyzer. The analysis employs
differential checking to identify inconsistent security operations
(e.g., checks or kfrees) between two code paths and confirms that the
inconsistent operations are not recovered in the current function or
the callers, so they constitute bugs.

Note that, as a bug found by static analysis, it can be a false
positive or hard to trigger. Multiple researchers have cross-reviewed
the bug.

Builds with CONFIG_ATH11K=m show no new warnings, and our static
analyzer no longer warns about this code.

anyway. Make sure to unregister an instance from the hotplug handler

[ Upstream commit 4754eab7e5a78bdefe7a960c5c260c95ebbb5fa6 ]

Steven Maddox reported in the OpenWrt bugzilla, that his
RaidSonic IB-NAS4220-B was no longer booting with the new
OpenWrt 21.02 (uses linux 5.10's device-tree). However, it was
working with the previous OpenWrt 19.07 series (uses 4.14).

|[    7.039504] Waiting for root device /dev/mtdblock3...

The provided bootlog shows that the RedBoot partition parser was
looking for the partition table "at offset 0x0". Which is strange
since the comment in the device-tree says it should be at 0xfe0000.

Further digging on the internet led to a review site that took
some useful PCB pictures of their review unit back in February 2009.
Their picture shows a Spansion S29GL128N11TFI01 flash chip.

>From Spansion's Datasheet:
"S29GL128N: One hundred twenty-eight 64 Kword (128 Kbyte) sectors"
Steven also provided a "cat /sys/class/mtd/mtd0/erasesize" from his
unit: "131072".

With the 128 KiB Sector/Erasesize in mind. This patch changes the
fis-index-block property to (0xfe0000 / 0x20000) = 0x7f.

3d3fbbf05f spi: Fix incorrect cs_setup delay handling
[ Upstream commit 95c07247399536f83b89dc60cfe7b279d17e69f6 ]

Move the cs_setup delay to the end of spi_set_cs.

From include/linux/spi/spi.h:

 * @cs_setup: delay to be introduced by the controller after CS is
   asserted

The cs_setup delay needs to happen *after* CS is asserted, that is, at
the end of spi_set_cs, not at the beginning. Otherwise we're just
delaying before the SPI transaction starts at all, which isn't very
useful.

No drivers use this right now, but that is likely to change soon with an
upcoming Apple SPI HID transport driver.

[ Upstream commit 3f9dd4c802b96626e869b2d29c8e401dabadd23e ]

When hisi_qm_resume() returns 0, it indicates that the device has started
successfully.  If the device fails to start, hisi_qm_resume() needs to
return the actual error code to the caller instead of 0.

[ Upstream commit 3d6b661330a7954d8136df98160d525eb04dcd6a ]

We should not call pm_runtime_resume_and_get where the reference
count is expected to be incremented unconditionally.  This patch
reverts these calls to the original unconditional get_sync call.

2383a52088 crypto: stm32/cryp - fix bugs and crash in tests
[ Upstream commit 4b898d5cfa4d9a0ad5bc82cb5eafdc092394c6a9 ]

Extra crypto manager auto test were crashing or failling due
to 2 reasons:
- block in a dead loop (dues to issues in cipher end process management)
- crash due to read/write unmapped memory (this crash was also reported
when using openssl afalg engine)

Rework interrupt management, interrupts are masked as soon as they are
no more used: if input buffer is fully consumed, "Input FIFO not full"
interrupt is masked and if output buffer is full, "Output FIFO not
empty" interrupt is masked.
And crypto request finish when input *and* outpout buffer are fully
read/write.

About the crash due to unmapped memory, using scatterwalk_copychunks()
that will map and copy each block fix the issue.
Using this api and copying full block will also fix unaligned data
access, avoid early copy of in/out buffer, and make useless the extra
alignment constraint.

[ Upstream commit fa97dc2d48b476ea98199d808d3248d285987e99 ]

This fixes the lrw autotest if lrw uses the CRYP as the AES block cipher
provider (as ecb(aes)). At end of request, CRYP should not update the IV
in case of ECB chaining mode. Indeed the ECB chaining mode never uses
the IV, but the software LRW chaining mode uses the IV field as
a counter and due to the (unexpected) update done by CRYP while the AES
block process, the counter get a wrong value when the IV overflow.

Don't erase key:
If key is erased before the crypto_finalize_.*_request() call, some
pending process will run with a key={ 0 }.
Moreover if the key is reset at end of request, it breaks xts chaining
mode, as for last xts block (in case input len is not a multiple of
block) a new AES request is started without calling again set_key().

[ Upstream commit 3abedf4646fdc0036fcb8ebbc3b600667167fafe ]

Test can fail either immediately when ASSERT() failed or at the
end if one or more EXPECT() was not met. The exact return code
is decided based on the number of successful ASSERT()s.

If test has no ASSERT()s, however, the return code will be 0,
as if the test did not fail. Start counting ASSERT()s from 1.
