tpm_buf_append_name() supports callers passing a pre-computed name for handles. When name is non-NULL, the code skips the tpm2_read_public() path but leaves name_size_alg uninitialized before it is used as the memcpy size argument. No current in-tree caller passes a non-NULL name, but future use cases such as name caching would exercise this path. Initialize name_size_alg by calling name_size() on the caller-provided name, sharing the error check and assignment with the existing tpm2_read_public() path. This prevents unmasking a latent bug when the non-NULL name path is eventually used.

Some TPMs fail to grant locality when requested immediately after being relinquished. In this case, the TPM_ACCESS_REQUEST_USE bit of the TPM_ACCESS register is cleared immediately without setting TPM_ACCESS_ACTIVE_LOCALITY. This issue can be seen at boot since tpm_chip_start, called right after locality is relinquished, will fail. This causes the probe to fail: tpm_tis MSFT0101:00: probe with driver tpm_tis failed with error -1 This occurs on some older Dell Latitudes.

tpm_buf_append_salt() in drivers/char/tpm/tpm2-sessions.c calls crypto_kpp_generate_public_key() and crypto_kpp_compute_shared_secret() without installing a completion callback, discards both return values, and immediately frees the kpp_request via kpp_request_free(). When the resolved ecdh-nist-p256 KPP backend is asynchronous (atmel-ecc, HPRE, keembay-ocs), either operation returns -EINPROGRESS and the deferred completion worker dereferences the freed request. The path fires automatically from the hwrng_fillfn kernel thread via tpm_get_random -> tpm2_get_random -> tpm2_start_auth_session -> tpm_buf_append_salt on every entropy poll, without any userland action. Install crypto_req_done as the completion callback, wrap both KPP operations in crypto_wait_req(), and propagate errors to the caller. The wait is a no-op for synchronous backends.

Commit 186d124 ("tpm_eventlog.c: fix binary_bios_measurements") split the output to write the endian-converted event header first and then the variable-length event data. However, the split was at sizeof(struct tcpa_event) - 1, even though event_data was a zero-length array, and later a flexible array member, both of which already excluded the event data. Therefore, the current code writes the first three bytes of event_size from the endian-converted header and then the last byte from the raw header, which can emit a corrupted event_size on PPC64, where do_endian_conversion() maps to be32_to_cpu(). Split one byte later to write the full endian-converted header first, followed by the variable-length event->event_data.

The RX event remains enabled because in this short window the RX event
was disabled in ->shutdown() while the interrupt was active and then
enabled again by the ISR while ->shutdown waited in free_irq().
This race requires timing and if happens can be problematic on shared
handlers if the "removed" channel triggers an interrupt. In this case
the irq-core will shutdown the interrupt with the "nobody cared"
message.
Introduce imx_mu_con_priv::shutdown to signal that the channel is
shutting down. This flag is set with the lock held (by
imx_mu_xcr_clr_shut()). The unmask side uses imx_mu_xcr_set_act() which
only enables the event if the channel has not been shutdown and
serialises on the same lock.

sashiko complained about early usage of the device while probe isn't completed. This can be mitigated by delaying the pm_runtime_enable() into the removal path instead doing it early. This ensures that in an error case the device is removed (and imx_mu_shutdown()) before pm_runtime_disable() so we don't have to do this manually. For the order to work, lets move devm_mbox_controller_register() until after the pm-runtime part. So the reverse order will be mbox-controller removal followed by disabling pm runtime.

… handler Split the mailbox irq handling into a primary handler (imx_mu_isr()) and a threaded handler (imx_mu_isr_th()). The primary handler masks the interrupt event so the threaded handler can run without raising the interrupt again. The goal here is to invoke the mailbox core functions (such as mbox_chan_received_data(), mbox_chan_txdone()) in preemptible context which is made possible by using an threaded interrupt handler. This in turn means that mailbox's client callbacks are invoked in preemptible context, too. This then allows the mailbox client callback to skip an indirection via a workqueue if it requries preemptible callback. As a first step, prepare the logic and move TX handling part.

The primary interrupt handler (imx_mu_isr()) no longer invokes any callbacks it only masks the interrupt source and returns.

The primary handler uses a spinlock_t to protect the RMW operation in imx_mu_xcr_rmw() - nothing that may introduce long latencies. The lock can be turned into a raw_spinlock_t and then the primary handler can run in hardirq context even on PREEMPT_RT skipping one thread.

When p9_client_walk() is called with clone set to false, fid aliases oldfid. If the walk subsequently fails after the request has been sent, the error path jumps to clunk_fid, which currently calls p9_fid_put(fid) unconditionally. This drops a reference to oldfid even though ownership of oldfid remains with the caller. If this is the last reference, oldfid can be clunked and destroyed while the caller still expects it to be valid. A later use or put of oldfid can then trigger a use-after-free or refcount underflow. Fix this by only putting fid in the clunk_fid error path when it does not alias oldfid, matching the existing guard in the error path below. This can be triggered when a multi-component walk is split into multiple p9_client_walk() calls and a later non-cloning walk fails. A reproducer and refcount warning logs are available on request.

Not caching negative dentries can result in poor performance for workloads that repeatedly look up non-existent paths. Each such lookup triggers a full 9P transaction with the server, adding unnecessary overhead. A typical example is source compilation, where multiple cc1 processes are spawned and repeatedly search for the same missing header files over and over again. This change enables caching of negative dentries, so that lookups for known non-existent paths do not require a full 9P transaction. The cached negative dentries are retained for a configurable duration (expressed in milliseconds), as specified by the ndentry_timeout field in struct v9fs_session_info. If set to -1, negative dentries are cached indefinitely. This optimization reduces lookup overhead and improves performance for workloads involving frequent access to non-existent paths.

fscrypt_finalize_bounce_page() should be called only if we use fs layer crypto, let's avoid unnecessary fscrypt_finalize_bounce_page() in error path of f2fs_write_compressed_pages(). BTW, fscrypt_finalize_bounce_page() will check mapping of bounced page before retrieving original page, so, previously it won't cause any issue w/ fscrypt_finalize_bounce_page(), but still we'd better avoid coupling w/ any logic inside fscrypt_finalize_bounce_page().

F2FS iostat is optional and is disabled by default. Direct I/O still
allocates and binds a bio_iostat_ctx, updates the submit timestamp, and
replaces bi_end_io for every DIO bio even when sbi->iostat_enable is
false.
The byte accounting calls do not need an extra guard because
f2fs_update_iostat() already checks sbi->iostat_enable. Only skip the
DIO bio context setup when iostat is disabled. If iostat is enabled
through sysfs before submission, the existing context allocation and
latency accounting path is still used.

Currently, the length of fallocate for pin file is section-aligned to
keep allocated sections from being selected as victims of GC. However,
for the case that the start offset of fallocate is not aligned in
section, the allocated sections can't be fully utilized. It's because a
new section is allocated by f2fs_allocate_pinning_section() after using
blks_per_sec blocks regardless of the start offset. As a result, several
unexpected dirty segments may be created, including blocks assigned to
the pinned file.
To address this issue, let's round down the start offset of fallocate
to the length of section.
The reproducing scenario is as below
chunk=$(((2<<20)+4096)) # 2MB + 4KB
touch test
f2fs_io pinfile set test
f2fs_io fallocate 0 0 $chunk test
f2fs_io fallocate 0 $chunk $chunk test

The sources under kernel/sched/ext/ build as a single translation unit: build_policy.c includes the source files and headers. An LSP/clangd editor parses each as a standalone unit, sees no types, and reports a flood of errors. Give each header its dependencies and include guard, and have each source include the headers it uses. ext.c, arena.c and the ext headers now parse clean standalone. idle.c and cid.c still reference a few macros and helpers defined in ext.c. The next patch moves those to shared headers. Suggested-by: Peter Zijlstra <peterz@infradead.org> Signed-off-by: Tejun Heo <tj@kernel.org> Reviewed-by: Andrea Righi <arighi@nvidia.com>
idle.c and cid.c are included into build_policy.c together with ext.c and use helpers that ext.c defines. Because the helpers live in ext.c, the two files can not parse as standalone units and clangd reports errors in them. Move the helpers to the headers they belong to.

Pull erofs updates from Gao Xiang:
"The most notable change is the removal of the fscache backend: it has
been deprecated for almost two years, mainly because EROFS file-backed
mounts and fanotify pre-content hooks (together with erofs-utils) now
provide better functionality and simpler codebase. In addition,
fscache has depended on netfslib for years, which is undesirable for
EROFS since it is a local filesystem. More details in [1].
In addition, sparse support has been added to the pcluster layout,
which is helpful for large sparse AI datasets, and map requests for
chunk-based inodes have been optimized to be more efficient as well.
There are also the usual fixes and cleanups.
Summary:
- Report more consecutive chunks of the same type for
each iomap request
- Add sparse support for the pcluster layout
- Update the EROFS documentation overview
- Remove the deprecated fscache backend
- Various fixes and cleanups"
