[PATCH AUTOSEL 5.10 01/50] arm64: zynqmp: Do not duplicate flash partition label property

[PATCH AUTOSEL 5.10 01/50] arm64: zynqmp: Do not duplicate flash partition label property

[Sasha Levin]

From: Amit Kumar Mahapatra <amit.kumar-mahapatra@xilinx.com>

[ Upstream commit 167721a5909f867f8c18c8e78ea58e705ad9bbd4 ]

In kernel 5.4, support has been added for reading MTD devices via the nvmem
API.
For this the mtd devices are registered as read-only NVMEM providers under
sysfs with the same name as the flash partition label property.

So if flash partition label property of multiple flash devices are
identical then the second mtd device fails to get registered as a NVMEM
provider.

This patch fixes the issue by having different label property for different
flashes.

[PATCH AUTOSEL 5.10 02/50] arm64: zynqmp: Fix serial compatible string

[Sasha Levin]

From: Michal Simek <michal.simek@xilinx.com>

[ Upstream commit 812fa2f0e9d33564bd0131a69750e0d165f4c82a ]

Based on commit 65a2c14d4f00 ("dt-bindings: serial: convert Cadence UART
bindings to YAML") compatible string should look like differently that's
why fix it to be aligned with dt binding.

[PATCH AUTOSEL 5.10 03/50] ARM: dts: sunxi: Fix OPPs node name

[Sasha Levin]

From: Maxime Ripard <maxime@cerno.tech>

[ Upstream commit ffbe853a3f5a37fa0a511265b21abf097ffdbe45 ]

The operating-points-v2 nodes are named inconsistently, but mostly
either opp_table0 or gpu-opp-table.  However, the underscore is an
invalid character for a node name and the thermal zone binding
explicitly requires that zones are called opp-table-*. Let's fix it.

[PATCH AUTOSEL 5.10 06/50] staging: wfx: ensure IRQ is ready before enabling it

From: Jérôme Pouiller <jerome.pouiller@silabs.com>

[ Upstream commit 5e57c668dc097c6c27c973504706edec53f79281 ]

Since commit 5561770f80b1 ("staging: wfx: repair external IRQ for
SDIO"), wfx_sdio_irq_subscribe() enforce the device to use IRQs.
However, there is currently a race in this code. An IRQ may happen
before the IRQ has been registered.

The problem has observed during debug session when the device crashes
before the IRQ set up:

[PATCH AUTOSEL 5.10 07/50] ARM: dts: NSP: Fix mpcore, mmc node names

[Sasha Levin]

From: Matthew Hagan <mnhagan88@gmail.com>

[ Upstream commit 15a563d008ef9d04df525f0c476cd7d7127bb883 ]

Running dtbs_check yielded the issues with bcm-nsp.dtsi.

Firstly this patch fixes the following message by appending "-bus" to
the mpcore node name:
mpcore@19000000: $nodename:0: 'mpcore@19000000' does not match '^([a-z][a-z0-9\\-]+-bus|bus|soc|axi|ahb|apb)(@[0-9a-f]+)?$'

Secondly mmc node name. The label name can remain as is.
sdhci@21000: $nodename:0: 'sdhci@21000' does not match '^mmc(@.*)?$'

[PATCH AUTOSEL 5.10 08/50] scsi: lpfc: Fix list_add() corruption in lpfc_drain_txq()

[Sasha Levin]

From: James Smart <jsmart2021@gmail.com>

[ Upstream commit 99154581b05c8fb22607afb7c3d66c1bace6aa5d ]

When parsing the txq list in lpfc_drain_txq(), the driver attempts to pass
the requests to the adapter. If such an attempt fails, a local "fail_msg"
string is set and a log message output.  The job is then added to a
completions list for cancellation.

Processing of any further jobs from the txq list continues, but since
"fail_msg" remains set, jobs are added to the completions list regardless
of whether a wqe was passed to the adapter.  If successfully added to
txcmplq, jobs are added to both lists resulting in list corruption.

Fix by clearing the fail_msg string after adding a job to the completions
list. This stops the subsequent jobs from being added to the completions
list unless they had an appropriate failure.

[PATCH AUTOSEL 5.10 09/50] arm64: dts: rockchip: Disable CDN DP on Pinebook Pro

[Sasha Levin]

From: Matthias Brugger <mbrugger@suse.com>

[ Upstream commit 2513fa5c25d42f55ca5f0f0ab247af7c9fbfa3b1 ]

The CDN DP needs a PHY and a extcon to work correctly. But no extcon is
provided by the device-tree, which leads to an error:
cdn-dp fec00000.dp: [drm:cdn_dp_probe [rockchipdrm]] *ERROR* missing extcon or phy
cdn-dp: probe of fec00000.dp failed with error -22

Disable the CDN DP to make graphic work on the Pinebook Pro.

When VF is configured with default vlan, HW strips the vlan from the
packet and driver receives it in Rx completion. VLAN needs to be reported
for UD work completion only if the vlan is configured on the host. Add a
check for valid vlan in the UD receive path.

[PATCH AUTOSEL 5.10 13/50] bus: ti-sysc: Add quirk handling for reinit on context lost

[Sasha Levin]

From: Tony Lindgren <tony@atomide.com>

[ Upstream commit 9d881361206ebcf6285c2ec2ef275aff80875347 ]

Some interconnect target modules such as otg and gpmc on am335x need a
re-init after resume. As we also have PM runtime cases where the context
may be lost, let's handle these all with cpu_pm.

For the am335x resume path, we already have cpu_pm_resume() call
cpu_pm_cluster_exit().

[PATCH AUTOSEL 5.10 14/50] bus: ti-sysc: Use context lost quirks for gpmc

[Sasha Levin]

From: Tony Lindgren <tony@atomide.com>

[ Upstream commit d48dca51935b8ca13356e726442c21ec94668d69 ]

At least on am335x, the gpmc module needs a re-init and reset if context
has been lost on resume. We can enable this for all gpmc revisions as we
check if the context was lost before restoring it.

From: Tony Lindgren <tony@atomide.com>

[ Upstream commit 9067839ff45a528bcb015cc2f24f656126b91e3f ]

Let's use SYSC_QUIRK_REINIT_ON_CTX_LOST quirk for am335x otg instead of
SYSC_QUIRK_REINIT_ON_RESUME quirk as we can now handle the context loss
in a more generic way.

This happens because when we enqueue a frame for
transmission we do it under xmit_priv lock, then calling
rtw_get_stainfo (needed for enqueuing) takes sta_hash_lock
and this leads to the following lock dependency:

xmit_priv->lock -> sta_hash_lock

Turning off a connection will bring to call
rtw_free_assoc_resources which will set up
the inverse dependency:

sta_hash_lock -> xmit_priv_lock

This could lead to a deadlock as lockdep complains.

Fix it by removing the xmit_priv->lock around
rtw_xmitframe_enqueue call inside rtl8723bs_hal_xmit
and put it in a smaller critical section inside
rtw_xmit_classifier, the only place where
xmit_priv data are actually accessed.

Replace spin_{lock,unlock}_bh(pxmitpriv->lock)
in other tx paths leading to rtw_xmitframe_enqueue
call with spin_{lock,unlock}_bh(psta->sleep_q.lock)
- it's not clear why accessing a sleep_q was protected
by a spinlock on xmitpriv->lock.

This way is avoided the same faulty lock nesting
order.

Extra changes in v2 by Hans de Goede:
-Lift the taking of the struct __queue.lock spinlock out of
 rtw_free_xmitframe_queue() into the callers this allows also
 protecting a bunch of related state in rtw_free_stainfo():
-Protect psta->sleepq_len on rtw_free_xmitframe_queue(&psta->sleep_q);
-Protect struct tx_servq.tx_pending and tx_servq.qcnt when
 calling rtw_free_xmitframe_queue(&tx_servq.sta_pending)
-This also allows moving the spin_lock_bh(&pxmitpriv->lock); to below
 the sleep_q free-ing code, avoiding another ABBA locking issue

[PATCH AUTOSEL 5.10 20/50] ARM: BCM53016: Specify switch ports for Meraki MR32

[Sasha Levin]

From: Christian Lamparter <chunkeey@gmail.com>

[ Upstream commit 6abc4ca5a28070945e0d68cb4160b309bfbf4b8b ]

the switch identifies itself as a BCM53012 (rev 5)...
This patch has been tested & verified on OpenWrt's
snapshot with Linux 5.10 (didn't test any older kernels).
The MR32 is able to "talk to the network" as before with
OpenWrt's SWITCHDEV b53 driver.

[PATCH AUTOSEL 5.10 21/50] arm64: dts: qcom: msm8998: Fix CPU/L2 idle state latency and residency

[Sasha Levin]

From: AngeloGioacchino Del Regno <angelogioacchino.delregno@somainline.org>

[ Upstream commit 3f1dcaff642e75c1d2ad03f783fa8a3b1f56dd50 ]

The entry/exit latency and minimum residency in state for the idle
states of MSM8998 were ..bad: first of all, for all of them the
timings were written for CPU sleep but the min-residency-us param
was miscalculated (supposedly, while porting this from downstream);
Then, the power collapse states are setting PC on both the CPU
cluster *and* the L2 cache, which have different timings: in the
specific case of L2 the times are higher so these ones should be
taken into account instead of the CPU ones.

This parameter misconfiguration was not giving particular issues
because on MSM8998 there was no CPU scaling at all, so cluster/L2
power collapse was rarely (if ever) hit.
When CPU scaling is enabled, though, the wrong timings will produce
SoC unstability shown to the user as random, apparently error-less,
sudden reboots and/or lockups.

This set of parameters are stabilizing the SoC when CPU scaling is
ON and when power collapse is frequently hit.

[PATCH AUTOSEL 5.10 26/50] clk: imx: imx6ul: Move csi_sel mux to correct base register

[Sasha Levin]

From: Stefan Riedmueller <s.riedmueller@phytec.de>

[ Upstream commit 2f9d61869640f732599ec36b984c2b5c46067519 ]

The csi_sel mux register is located in the CCM register base and not the
CCM_ANALOG register base. So move it to the correct position in code.

Otherwise changing the parent of the csi clock can lead to a complete
system failure due to the CCM_ANALOG_PLL_SYS_TOG register being falsely
modified.

Also remove the SET_RATE_PARENT flag since one possible supply for the
csi_sel mux is the system PLL which we don't want to modify.

From: Hans de Goede <hdegoede@redhat.com>

[ Upstream commit 92d3360108f1839ca40451bad20ff67dd24a1964 ]

Add a quirk mechanism to allow specifying that active-high jack-detection
should be used on platforms where this info is not available in devicetree.

And add an entry for the Cyberbook T116 tablet to the DMI table, so that
jack-detection will work properly on this tablet.

[PATCH AUTOSEL 5.10 28/50] scsi: advansys: Fix kernel pointer leak

[Sasha Levin]

From: Guo Zhi <qtxuning1999@sjtu.edu.cn>

[ Upstream commit d4996c6eac4c81b8872043e9391563f67f13e406 ]

Pointers should be printed with %p or %px rather than cast to 'unsigned
long' and printed with %lx.

Change %lx to %p to print the hashed pointer.

[PATCH AUTOSEL 5.10 31/50] firmware_loader: fix pre-allocated buf built-in firmware use

[Sasha Levin]

From: Luis Chamberlain <mcgrof@kernel.org>

[ Upstream commit f7a07f7b96033df7709042ff38e998720a3f7119 ]

The firmware_loader can be used with a pre-allocated buffer
through the use of the API calls:

  o request_firmware_into_buf()
  o request_partial_firmware_into_buf()

If the firmware was built-in and present, our current check
for if the built-in firmware fits into the pre-allocated buffer
does not return any errors, and we proceed to tell the caller
that everything worked fine. It's a lie and no firmware would
end up being copied into the pre-allocated buffer. So if the
caller trust the result it may end up writing a bunch of 0's
to a device!

Fix this by making the function that checks for the pre-allocated
buffer return non-void. Since the typical use case is when no
pre-allocated buffer is provided make this return successfully
for that case. If the built-in firmware does *not* fit into the
pre-allocated buffer size return a failure as we should have
been doing before.

I'm not aware of users of the built-in firmware using the API
calls with a pre-allocated buffer, as such I doubt this fixes
any real life issue. But you never know... perhaps some oddball
private tree might use it.

In so far as upstream is concerned this just fixes our code for
correctness.

Check whether PMC is ready before proceeding with the cpuidle registration.
This fixes racing with the PMC driver probe order, which results in a
disabled deepest CC6 idling state if cpuidle driver is probed before the
PMC.

[PATCH AUTOSEL 5.10 38/50] tty: tty_buffer: Fix the softlockup issue in flush_to_ldisc

[Sasha Levin]

From: Guanghui Feng <guanghuifeng@linux.alibaba.com>

[ Upstream commit 3968ddcf05fb4b9409cd1859feb06a5b0550a1c1 ]

When running ltp testcase(ltp/testcases/kernel/pty/pty04.c) with arm64, there is a soft lockup,
which look like this one:

  Workqueue: events_unbound flush_to_ldisc
  Call trace:

   process_one_work+0x1d4/0x4b0
   worker_thread+0x180/0x430
   kthread+0x11c/0x120

In the testcase pty04, The first process call the write syscall to send
data to the pty master. At the same time, the workqueue will do the
flush_to_ldisc to pop data in a loop until there is no more data left.
When the sender and workqueue running in different core, the sender sends
data fastly in full time which will result in workqueue doing work in loop
for a long time and occuring softlockup in flush_to_ldisc with kernel
configured without preempt. So I add need_resched check and cond_resched
in the flush_to_ldisc loop to avoid it.

In resp_readcap16() we get "int alloc_len" value -1104926854, and then pass
the huge arr_len to fill_from_dev_buffer(), but arr is only 32 bytes. This
leads to OOB in sg_copy_buffer().

To solve this issue, define alloc_len as u32.

[PATCH AUTOSEL 5.10 42/50] scsi: target: Fix ordered tag handling

[Sasha Levin]

From: Mike Christie <michael.christie@oracle.com>

[ Upstream commit ed1227e080990ffec5bf39006ec8a57358e6689a ]

This patch fixes the following bugs:

1. If there are multiple ordered cmds queued and multiple simple cmds
   completing, target_restart_delayed_cmds() could be called on different
   CPUs and each instance could start a ordered cmd. They could then run in
   different orders than they were queued.

2. target_restart_delayed_cmds() and target_handle_task_attr() can race
   where:

   1. target_handle_task_attr() has passed the simple_cmds == 0 check.

   2. transport_complete_task_attr() then decrements simple_cmds to 0.

   3. transport_complete_task_attr() runs target_restart_delayed_cmds() and
      it does not see any cmds on the delayed_cmd_list.

   4. target_handle_task_attr() adds the cmd to the delayed_cmd_list.

   The cmd will then end up timing out.

3. If we are sent > 1 ordered cmds and simple_cmds == 0, we can execute
   them out of order, because target_handle_task_attr() will hit that
   simple_cmds check first and return false for all ordered cmds sent.

4. We run target_restart_delayed_cmds() after every cmd completion, so if
   there is more than 1 simple cmd running, we start executing ordered cmds
   after that first cmd instead of waiting for all of them to complete.

5. Ordered cmds are not supposed to start until HEAD OF QUEUE and all older
   cmds have completed, and not just simple.

6. It's not a bug but it doesn't make sense to take the delayed_cmd_lock
   for every cmd completion when ordered cmds are almost never used. Just
   replacing that lock with an atomic increases IOPs by up to 10% when
   completions are spread over multiple CPUs and there are multiple
   sessions/ mqs/thread accessing the same device.

This patch moves the queued delayed handling to a per device work to
serialze the cmd executions for each device and adds a new counter to track
HEAD_OF_QUEUE and SIMPLE cmds. We can then check the new counter to
determine when to run the work on the completion path.

[PATCH AUTOSEL 5.10 43/50] scsi: target: Fix alua_tg_pt_gps_count tracking

[Sasha Levin]

From: Mike Christie <michael.christie@oracle.com>

[ Upstream commit 1283c0d1a32bb924324481586b5d6e8e76f676ba ]

We can't free the tg_pt_gp in core_alua_set_tg_pt_gp_id() because it's
still accessed via configfs. Its release must go through the normal
configfs/refcount process.

The max alua_tg_pt_gps_count check should probably have been done in
core_alua_allocate_tg_pt_gp(), but with the current code userspace could
have created 0x0000ffff + 1 groups, but only set the id for 0x0000ffff.
Then it could have deleted a group with an ID set, and then set the ID for
that extra group and it would work ok.

It's unlikely, but just in case this patch continues to allow that type of
behavior, and just fixes the kfree() while in use bug.

[PATCH AUTOSEL 5.10 44/50] iio: imu: st_lsm6dsx: Avoid potential array overflow in st_lsm6dsx_set_odr()

[Sasha Levin]

From: Teng Qi <starmiku1207184332@gmail.com>

[ Upstream commit 94be878c882d8d784ff44c639bf55f3b029f85af ]

The length of hw->settings->odr_table is 2 and ref_sensor->id is an enum
variable whose value is between 0 and 5.
However, the value ST_LSM6DSX_ID_MAX (i.e. 5) is not caught properly in
 switch (sensor->id) {

If ref_sensor->id is ST_LSM6DSX_ID_MAX, an array overflow will ocurrs in
function st_lsm6dsx_check_odr():
  odr_table = &sensor->hw->settings->odr_table[sensor->id];

and in function st_lsm6dsx_set_odr():
  reg = &hw->settings->odr_table[ref_sensor->id].reg;

To avoid this array overflow, handle ST_LSM6DSX_ID_GYRO explicitly and
return -EINVAL for the default case.

The enum value ST_LSM6DSX_ID_MAX is only present as an easy way to check
the limit and as such is never used, however this is not locally obvious.

[PATCH AUTOSEL 5.10 46/50] arm64: dts: qcom: msm8916: Add CPU ACC and SAW/SPM

[Sasha Levin]

From: Stephan Gerhold <stephan@gerhold.net>

[ Upstream commit a22f9a766e1dc61f8f6ee2edfe83d4d23d78e059 ]

Add the device tree nodes necessary for SMP bring-up and cpuidle
without PSCI on ARM32. The hardware is typically controlled by the
PSCI implementation in the TrustZone firmware and is therefore marked
as status = "reserved" by default (from the device tree specification):

  "Indicates that the device is operational, but should not be used.
   Typically this is used for devices that are controlled by another
   software component, such as platform firmware."

Since this is part of the MSM8916 SoC it should be added to msm8916.dtsi
but in practice these nodes should only get enabled via an extra include
on ARM32.

This is necessary for some devices with signed firmware which is missing
both ARM64 and PSCI support and can therefore only boot ARM32 kernels.

[PATCH AUTOSEL 5.10 48/50] ALSA: gus: fix null pointer dereference on pointer block

[Sasha Levin]

From: Chengfeng Ye <cyeaa@connect.ust.hk>

[ Upstream commit a0d21bb3279476c777434c40d969ea88ca64f9aa ]

The pointer block return from snd_gf1_dma_next_block could be
null, so there is a potential null pointer dereference issue.
Fix this by adding a null check before dereference.

[PATCH AUTOSEL 5.10 49/50] powerpc/dcr: Use cmplwi instead of 3-argument cmpli

[Sasha Levin]

From: Michael Ellerman <mpe@ellerman.id.au>

[ Upstream commit fef071be57dc43679a32d5b0e6ee176d6f12e9f2 ]

In dcr-low.S we use cmpli with three arguments, instead of four
arguments as defined in the ISA:

	cmpli	cr0,r3,1024

This appears to be a PPC440-ism, looking at the "PPC440x5 CPU Core
User’s Manual" it shows cmpli having no L field, but implied to be 0 due
to the core being 32-bit. It mentions that the ISA defines four
arguments and recommends using cmplwi.

It also corresponds to the old POWER instruction set, which had no L
field there, a reserved bit instead.

dcr-low.S is only built 32-bit, because it is only built when
DCR_NATIVE=y, which is only selected by 40x and 44x. Looking at the
generated code (with gcc/gas) we see cmplwi as expected.

Although gas is happy with the 3-argument version when building for
32-bit, the LLVM assembler is not and errors out with:

  arch/powerpc/sysdev/dcr-low.S:27:10: error: invalid operand for instruction
   cmpli 0,%r3,1024; ...
           ^

Switch to the cmplwi extended opcode, which avoids any confusion when
reading the ISA, fixes the issue with the LLVM assembler, and also means
the code could be built 64-bit in future (though that's very unlikely).

[PATCH AUTOSEL 5.10 50/50] powerpc/8xx: Fix Oops with STRICT_KERNEL_RWX without DEBUG_RODATA_TEST

[Sasha Levin]

From: Christophe Leroy <christophe.leroy@csgroup.eu>

[ Upstream commit c12ab8dbc492b992e1ea717db933cee568780c47 ]

Until now, all tests involving CONFIG_STRICT_KERNEL_RWX were done with
DEBUG_RODATA_TEST to check the result. But now that
CONFIG_STRICT_KERNEL_RWX is selected by default, it came without
CONFIG_DEBUG_RODATA_TEST and led to the following Oops
