505f4111dd jfs: fix metapage reference count leak in dbAllocCtl
[ Upstream commit 856db37592021e9155384094e331e2d4589f28b1 ]

In dbAllocCtl(), read_metapage() increases the reference count of the
metapage. However, when dp->tree.budmin < 0, the function returns -EIO
without calling release_metapage() to decrease the reference count,
leading to a memory leak.

Add release_metapage(mp) before the error return to properly manage
the metapage reference count and prevent the leak.

[ Upstream commit 6908c5f4f066a0412c3d9a6f543a09fa7d87824b ]

The `adf_ring_next()` function in the QAT debug transport interface
fails to correctly update the position index when reaching the end of
the ring elements. This triggers the following kernel warning when
reading ring files, such as
/sys/kernel/debug/qat_c6xx_<D:B:D:F>/transport/bank_00/ring_00:

Ensure that the `*pos` index is incremented before returning NULL when
after the last element in the ring is found, satisfying the seq_file API
requirements and preventing the warning.

1c178ccb6c crypto: qat - fix DMA direction for compression on GEN2 devices
[ Upstream commit d41d75fe1b751ee6b347bf1cb1cfe9accc4fcb12 ]

QAT devices perform an additional integrity check during compression by
decompressing the output. Starting from QAT GEN4, this verification is
done in-line by the hardware. However, on GEN2 devices, the hardware
reads back the compressed output from the destination buffer and performs
a decompression operation using it as the source.

In the current QAT driver, destination buffers are always marked as
write-only. This is incorrect for QAT GEN2 compression, where the buffer
is also read during verification. Since commit 6f5dc7658094
("iommu/vt-d: Restore WO permissions on second-level paging entries"),
merged in v6.16-rc1, write-only permissions are strictly enforced, leading
to DMAR errors when using QAT GEN2 devices for compression, if VT-d is
enabled.

Mark the destination buffers as DMA_BIDIRECTIONAL. This ensures
compatibility with GEN2 devices, even though it is not required for
QAT GEN4 and later.

106891c7bd sh: Do not use hyphen in exported variable name
[ Upstream commit c32969d0362a790fbc6117e0b6a737a7e510b843 ]

arch/sh/Makefile defines and exports ld-bfd to be used by
arch/sh/boot/compressed/Makefile and arch/sh/boot/romimage/Makefile.
However some shells, including dash, will not pass through environment
variables whose name includes a hyphen.  Usually GNU make does not use
a shell to recurse, but if e.g. $(srctree) contains '~' it will use a
shell here.

Other instances of this problem were previously fixed by commits
2bfbe7881e "kbuild: Do not use hyphen in exported variable name"
and 82977af93a "sh: rename suffix-y to suffix_y".

Rename the variable to ld_bfd.

25d15b0d2b fs/orangefs: Allow 2 more characters in do_c_string()
[ Upstream commit 2138e89cb066b40386b1d9ddd61253347d356474 ]

The do_k_string() and do_c_string() functions do essentially the same
thing which is they add a string and a comma onto the end of an existing
string.  At the end, the caller will overwrite the last comma with a
newline.  Later, in orangefs_kernel_debug_init(), we add a newline to
the string.

The change to do_k_string() is just cosmetic.  I moved the "- 1" to
the other side of the comparison and made it "+ 1".  This has no
effect on runtime, I just wanted the functions to match each other
and the rest of the file.

However in do_c_string(), I removed the "- 2" which allows us to print
two extra characters.  I noticed this issue while reviewing the code
and I doubt affects anything in real life.  My guess is that this was
double counting the comma and the newline.  The "+ 1" accounts for
the newline, and the caller will delete the final comma which ensures
there is enough space for the newline.

Removing the "- 2" lets us print 2 more characters, but mainly it makes
the code more consistent and understandable for reviewers.

b93d06499b PCI: endpoint: pci-epf-vntb: Fix the incorrect usage of __iomem attribute
[ Upstream commit 61ae7f8694fb4b57a8c02a1a8d2b601806afc999 ]

__iomem attribute is supposed to be used only with variables holding the

9b2a3e7189 pinmux: fix race causing mux_owner NULL with active mux_usecount
[ Upstream commit 0b075c011032f88d1cfde3b45d6dcf08b44140eb ]

commit 5a3e85c3c397 ("pinmux: Use sequential access to access
desc->pinmux data") tried to address the issue when two client of the
same gpio calls pinctrl_select_state() for the same functionality, was
resulting in NULL pointer issue while accessing desc->mux_owner.
However, issue was not completely fixed due to the way it was handled
and it can still result in the same NULL pointer.

The issue occurs due to the following interleaving:

     cpu0 (process A)                   cpu1 (process B)

      pin_request() {                   pin_free() {

                                         mutex_lock()
                                         desc->mux_usecount--; //becomes 0
                                         ..
                                         mutex_unlock()

  mutex_lock(desc->mux)
  desc->mux_usecount++; // becomes 1
  desc->mux_owner = owner;
  mutex_unlock(desc->mux)

                                         mutex_lock(desc->mux)
                                         desc->mux_owner = NULL;
                                         mutex_unlock(desc->mux)

This sequence leads to a state where the pin appears to be in use
(`mux_usecount == 1`) but has no owner (`mux_owner == NULL`), which can
cause NULL pointer on next pin_request on the same pin.

Ensure that updates to mux_usecount and mux_owner are performed
atomically under the same lock. Only clear mux_owner when mux_usecount
reaches zero and no new owner has been assigned.

9fe9f94599 perf tools: Fix use-after-free in help_unknown_cmd()
[ Upstream commit 1fdf938168c4d26fa279d4f204768690d1f9c4ae ]

Currently perf aborts when it finds an invalid command.  I guess it
depends on the environment as I have some custom commands in the path.

  $ perf bad-command
  perf: 'bad-command' is not a perf-command. See 'perf --help'.
  Aborted (core dumped)

It's because the exclude_cmds() in libsubcmd has a use-after-free when
it removes some entries.  After copying one to another entry, it keeps
the pointer in the both position.  And the next copy operation will free
the later one but it's the same entry in the previous one.

For example, let's say cmds = { A, B, C, D, E } and excludes = { B, E }.

  ci  cj  ei   cmds-name  excludes
  -----------+--------------------
   0   0   0 |     A         B       :    cmp < 0, ci == cj
   1   1   0 |     B         B       :    cmp == 0
   2   1   1 |     C         E       :    cmp < 0, ci != cj

At this point, it frees cmds->names[1] and cmds->names[1] is assigned to
cmds->names[2].

   3   2   1 |     D         E       :    cmp < 0, ci != cj

Now it frees cmds->names[2] but it's the same as cmds->names[1].  So
accessing cmds->names[1] will be invalid.

This makes the subcmd tests succeed.

  $ perf test subcmd

This could happen in theory if walk.nbytes is larger than INT_MAX and gets
converted to a negative local variable.

Keep the type unsigned like the orignal nbytes to be sure there is no
integer overflow.

f693be157c power: supply: max14577: Handle NULL pdata when CONFIG_OF is not set
[ Upstream commit 2937f5d2e24eefef8cb126244caec7fe3307f724 ]

When the kernel is not configured  CONFIG_OF, the max14577_charger_dt_init
function returns NULL. Fix the max14577_charger_probe functionby returning
-ENODATA instead of potentially passing a NULL pointer to PTR_ERR.

This fixes the below smatch warning:

[ Upstream commit 13de464f445d42738fe18c9a28bab056ba3a290a ]

devm_kasprintf() returns NULL when memory allocation fails. Currently,
davinci_lpsc_clk_register() does not check for this case, which results
in a NULL pointer dereference.

Add NULL check after devm_kasprintf() to prevent this issue and ensuring
no resources are left allocated.

530d4db6fb mtd: fix possible integer overflow in erase_xfer()
[ Upstream commit 9358bdb9f9f54d94ceafc650deffefd737d19fdd ]

The expression '1 << EraseUnitSize' is evaluated in int, which causes
a negative result when shifting by 31 - the upper bound of the valid
range [10, 31], enforced by scan_header(). This leads to incorrect
extension when storing the result in 'erase->len' (uint64_t), producing
a large unexpected value.

be1e15938a crypto: qat - use unmanaged allocation for dc_data
[ Upstream commit 4cc871ad0173e8bc22f80e3609e34d546d30ef1a ]

The dc_data structure holds data required for handling compression
operations, such as overflow buffers. In this context, the use of
managed memory allocation APIs (devm_kzalloc() and devm_kfree())
is not necessary, as these data structures are freed and
re-allocated when a device is restarted in adf_dev_down() and
adf_dev_up().

Additionally, managed APIs automatically handle memory cleanup when the
device is detached, which can lead to conflicts with manual cleanup
processes. Specifically, if a device driver invokes the adf_dev_down()
function as part of the cleanup registered with
devm_add_action_or_reset(), it may attempt to free memory that is also
managed by the device's resource management system, potentially leading
to a double-free.

This might result in a warning similar to the following when unloading
the device specific driver, for example qat_6xxx.ko:

    qat_free_dc_data+0x4f/0x60 [intel_qat]
    qat_compression_event_handler+0x3d/0x1d0 [intel_qat]
    adf_dev_shutdown+0x6d/0x1a0 [intel_qat]
    adf_dev_down+0x32/0x50 [intel_qat]
    devres_release_all+0xb8/0x110
    device_unbind_cleanup+0xe/0x70
    device_release_driver_internal+0x1c1/0x200
    driver_detach+0x48/0x90
    bus_remove_driver+0x74/0xf0
    pci_unregister_driver+0x2e/0xb0

Use unmanaged memory allocation APIs (kzalloc_node() and kfree()) for
the dc_data structure. This ensures that memory is explicitly allocated
and freed under the control of the driver code, preventing manual
deallocation from interfering with automatic cleanup.
