cafa992134 of: Fix double free in of_parse_phandle_with_args_map
[ Upstream commit 4dde835698 ]

In of_parse_phandle_with_args_map() the inner loop that
iterates through the map entries calls of_node_put(new)
to free the reference acquired by the previous iteration
of the inner loop. This assumes that the value of "new" is
NULL on the first iteration of the inner loop.

Make sure that this is true in all iterations of the outer
loop by setting "new" to NULL after its value is assigned to "cur".

Extend the unittest to detect the double free and add an additional
test case that actually triggers this path.

36fdccf845 ksmbd: validate the zero field of packet header
[ Upstream commit 516b3eb8c8 ]

The SMB2 Protocol requires that "The first byte of the Direct TCP
transport packet header MUST be zero (0x00)"[1]. Commit 1c1bcf2d3e
("ksmbd: validate smb request protocol id") removed the validation of
this 1-byte zero. Add the validation back now.

4f38581938 kselftest/alsa - conf: Stringify the printed errno in sysfs_get()

GCC 13.2.0 reported the warning of the print format specifier:

eb3f55156f kselftest/alsa - mixer-test: fix the number of parameters to ksft_exit_fail_msg()
[ Upstream commit 8c51c13dc6 ]

Minor fix in the number of arguments to error reporting function in the

mixer-test.c: In function ‘find_controls’:
mixer-test.c:169:44: warning: too many arguments for format [-Wformat-extra-args]

The number of arguments in call to ksft_exit_fail_msg() doesn't correspond
to the format specifiers, so this is adjusted resembling the sibling calls
to the error function.

e0fc60a44d drm/amd/pm/smu7: fix a memleak in smu7_hwmgr_backend_init
[ Upstream commit 2f3be3ca77 ]

The hwmgr->backend, (i.e. data) allocated by kzalloc is not freed in
the error-handling paths of smu7_get_evv_voltages and
smu7_update_edc_leakage_table. However, it did be freed in the
error-handling of phm_initializa_dynamic_state_adjustment_rule_settings,
by smu7_hwmgr_backend_fini. So the lack of free in smu7_get_evv_voltages
and smu7_update_edc_leakage_table is considered a memleak in this patch.

dc23b1ba2f IB/iser: Prevent invalidating wrong MR
[ Upstream commit 2f1888281e ]

The iser_reg_resources structure has two pointers to MR but only one
mr_valid field. The implementation assumes that we use only *sig_mr when
pi_enable is true. Otherwise, we use only *mr. However, it is only
sometimes correct. Read commands without protection information occur even
when pi_enble is true. For example, the following SCSI commands have a
Data-In buffer but never have protection information: READ CAPACITY (16),
INQUIRY, MODE SENSE(6), MAINTENANCE IN. So, we use
*sig_mr for some SCSI commands and *mr for the other SCSI commands.

In most cases, it works fine because the remote invalidation is applied.
However, there are two cases when the remote invalidation is not
applicable.
 1. Small write commands when all data is sent as an immediate.
 2. The target does not support the remote invalidation feature.

The lazy invalidation is used if the remote invalidation is impossible.
Since, at the lazy invalidation, we always invalidate the MR we want to
use, the wrong MR may be invalidated.

To fix the issue, we need a field per MR that indicates the MR needs
invalidation. Since the ib_mr structure already has such a field, let's
use ib_mr.need_inval instead of iser_reg_resources.mr_valid.

646df7c634 drm/mediatek: dp: Add phy_mtk_dp module as pre-dependency
[ Upstream commit c8048dd0b0 ]

The mtk_dp driver registers a phy device which is handled by the
phy_mtk_dp driver and assumes that the phy probe will complete
synchronously, proceeding to make use of functionality exposed by that
driver right away. This assumption however is false when the phy driver
is built as a module, causing the mtk_dp driver to fail probe in this
case.

Add the phy_mtk_dp module as a pre-dependency to the mtk_dp module to
ensure the phy module has been loaded before the dp, so that the phy
probe happens synchrounously and the mtk_dp driver can probe
successfully even with the phy driver built as a module.

a12d8891ff ASoC: amd: vangogh: Drop conflicting ACPI-based probing
[ Upstream commit ddd1ee12a8 ]

The Vangogh machine driver variant based on the MAX98388 amplifier, as
found on Valve's Steam Deck OLED, relies on probing via an ACPI match
table.  This worked fine until commit 197b1f7f0d ("ASoC: amd: Add new
dmi entries to config entry") enabled SOF support for the target machine
(i.e. Galileo product), causing the sound card to enter the deferred
probe state indefinitely:

$ cat /sys/kernel/debug/devices_deferred
AMDI8821:00	acp5x_mach: Register card (acp5x-max98388) failed

The issue is related to commit e89f45edb7 ("ASoC: amd: vangogh: Add
check for acp config flags in vangogh platform"), which tries to
mitigate potential conflicts between SOF and generic ACP Vangogh
drivers, due to sharing the PCI device IDs.

However, the solution is effective only if the machine driver is
directly probed by pci-acp5x through platform_device_register_full().

Hence, remove the conflicting ACPI based probing and rely exclusively on
DMI quirks for sound card setup.

a6ce482b1b watchdog/hpwdt: Only claim UNKNOWN NMI if from iLO
[ Upstream commit dced0b3e51 ]

Avoid unnecessary crashes by claiming only NMIs that are due to
ERROR signalling or generated by the hpwdt hardware device.

The code does this, but only for iLO5.

The intent was to preserve legacy, Gen9 and earlier, semantics of
using hpwdt for error containtment as hardware/firmware would signal
fatal IO errors as an NMI with the expectation of hpwdt crashing
the system.  Howerver, these IO errors should be received by hpwdt
as an NMI_IO_CHECK.  So the test is overly permissive and should
not be limited to only ilo5.

We need to enable this protection for future iLOs not matching the
current PCI IDs.

90c6cada50 watchdog: set cdev owner before adding
[ Upstream commit 38d7529774 ]

When the new watchdog character device is registered, it becomes
available for opening. This creates a race where userspace may open the
device before the character device's owner is set. This results in an
imbalance in module_get calls as the cdev_get in cdev_open will not
increment the reference count on the watchdog driver module.

This causes problems when the watchdog character device is released as
the module loader's reference will also be released. This makes it
impossible to open the watchdog device later on as it now appears that
the module is being unloaded. The open will fail with -ENXIO from
chrdev_open.

The legacy watchdog device will fail with -EBUSY from the try_module_get
in watchdog_open because it's module owner is the watchdog core module
so it can still be opened but it will fail to get a refcount on the
underlying watchdog device driver.

[ Upstream commit b782921ddd ]

Currently zynqmp clock driver is not calculating closest mux rate and
because of that Linux is not setting proper frequency for CPU and
not able to set given frequency for dynamic frequency scaling.

E.g., In current logic initial acpu clock parent and frequency as below
apll1                  0    0    0  2199999978    0     0  50000      Y
    acpu0_mux          0    0    0  2199999978    0     0  50000      Y
        acpu0_idiv1    0    0    0  2199999978    0     0  50000      Y
            acpu0      0    0    0  2199999978    0     0  50000      Y

After changing acpu frequency to 549999994 Hz using CPU freq scaling its
selecting incorrect parent which is not closest frequency.
rpll_to_xpd            0    0    0  1599999984    0     0  50000      Y
    acpu0_mux          0    0    0  1599999984    0     0  50000      Y
        acpu0_div1     0    0    0   533333328    0     0  50000      Y
            acpu0      0    0    0   533333328    0     0  50000      Y

Parent should remain same since 549999994 = 2199999978 / 4.

So use __clk_mux_determine_rate_closest() generic function to calculate
closest rate for mux clock. After this change its selecting correct
parent and correct clock rate.

[ Upstream commit 71f130c919 ]

When the driver was ported upstream, PLL test_ctl_hi1 register value
was omitted. Add it to ensure the PLLs are fully configured.

7348495bac f2fs: fix to check return value of f2fs_recover_xattr_data
[ Upstream commit 86d7d57a3f ]

Should check return value of f2fs_recover_xattr_data in
__f2fs_setxattr rather than doing invalid retry if error happen.

Also just do set_page_dirty in f2fs_recover_xattr_data when
page is changed really.

638942ccda drm/amd/pm: fix a double-free in amdgpu_parse_extended_power_table
[ Upstream commit a658270117 ]

The amdgpu_free_extended_power_table is called in every error-handling
paths of amdgpu_parse_extended_power_table. However, after the following
call chain of returning:

amdgpu_parse_extended_power_table
  |-> kv_dpm_init / si_dpm_init
      (the only two caller of amdgpu_parse_extended_power_table)
        |-> kv_dpm_sw_init / si_dpm_sw_init
            (the only caller of kv_dpm_init / si_dpm_init, accordingly)
              |-> kv_dpm_fini / si_dpm_fini
                  (goto dpm_failed in xx_dpm_sw_init)
                    |-> amdgpu_free_extended_power_table

As above, the amdgpu_free_extended_power_table is called twice in this
returning chain and thus a double-free is triggered. Similarily, the
last kfree in amdgpu_parse_extended_power_table also cause a double free
with amdgpu_free_extended_power_table in kv_dpm_fini.

3426f059ea drivers/amd/pm: fix a use-after-free in kv_parse_power_table
[ Upstream commit 28dd788382 ]

When ps allocated by kzalloc equals to NULL, kv_parse_power_table
frees adev->pm.dpm.ps that allocated before. However, after the control
flow goes through the following call chains:

kv_parse_power_table
  |-> kv_dpm_init
        |-> kv_dpm_sw_init
	      |-> kv_dpm_fini

The adev->pm.dpm.ps is used in the for loop of kv_dpm_fini after its
first free in kv_parse_power_table and causes a use-after-free bug.

[ Upstream commit ac16667237 ]

When the allocation of
adev->pm.dpm.dyn_state.vddc_dependency_on_dispclk.entries fails,
amdgpu_free_extended_power_table is called to free some fields of adev.
However, when the control flow returns to si_dpm_sw_init, it goes to
label dpm_failed and calls si_dpm_fini, which calls
amdgpu_free_extended_power_table again and free those fields again. Thus
a double-free is triggered.
