Pull networking updates from Jakub Kicinski:
"One of the 'small improvements all over the place' releases for us.
It's hard to draw any direct comparisons because summer vacations
disrupted our patch processing (and presumably - generation) quite a
bit.
Quick and dirty count suggests we (Paolo and I) merged a very similar
number of net (632) and net-next (648) patches. This is not telling
the full story either because 1/3 to 1/2 of the net-next patches also
*seem* like AI-driven low priority fixes, cleanups and clarifications.
We are completely overwhelmed, of course. The glimmer of hope is that
we secured sufficient LLM budget and access (thank you Meta!) to run
reviews with multiple frontier models on each patch. This eliminates
some hallucinations. That said, in terms of review, the LLMs can only
do so much.
The sad truth is that our APIs (especially for rare events like PCIe
errors, timeouts etc) have always been racy, and now LLMs don't let us
ignore that. I expect our direction for the next release will be to
tweak the reviews a little bit more, but start shifting focus to
letting the LLMs take care of the busy work - managing patchwork,
automating common process complaints, editing commit messages, and
maybe applying patches which already got "reviewed-by" tags from
people we trust...
Core & protocols:
- A few steps lowering rtnl_lock dependence:

In ls2k0500_mmc_reorder_cmd_data() and ls2k2000_mmc_reorder_cmd_data(),
the for_each_sg() macro already iterates over the scatterlist entries,
with 'sg' pointing to the current entry. However, the code incorrectly
uses '&sg[i]' and 'sg_dma_len(&sg[i])' inside the loop, which treats
'sg' as an array base and indexes it again, leading to access of
wrong sg entries (or out-of-bounds if the list is not an array).

omap_hsmmc_prepare_data() converts the command busy timeout to nanoseconds
with:
timeout = req->cmd->busy_timeout * NSEC_PER_MSEC;
busy_timeout is an unsigned int (milliseconds) and timeout is a u64, but
NSEC_PER_MSEC is 1000000L. On 32-bit builds the multiplication is
performed in 32-bit arithmetic and wraps for busy_timeout values above
~4294 ms, before the result is assigned to the u64.
The driver does not set mmc->max_busy_timeout, so the core does not cap the
busy timeout, and commands such as erase or SANITIZE (MMC_SANITIZE_TIMEOUT_MS
is 240000 ms) can pass a busy_timeout far larger than 4294 ms. The wrapped,
much smaller ns value is then programmed via set_data_timeout(), so the data
timeout is set too short and the operation can time out prematurely.
Cast busy_timeout to u64 before the multiplication so the conversion is done
in 64-bit arithmetic.

In atmci_probe, &host->bh_work is bound with atmci_work_func, and
atmci_interrupt, atmci_timeout_timer and atmci_dma_complete can all
queue this work on system_bh_wq.
If we remove the module, atmci_remove makes cleanup and the memory
allocated for host with devm_kzalloc() is released after the remove
callback returns, while the work mentioned above may still be pending
or running. The sequence of operations that may lead to a UAF bug is
as follows:
CPU0 CPU1
| atmci_interrupt
| queue_work(system_bh_wq,
| &host->bh_work)
atmci_remove |
atmci_cleanup_slot(...) |
atmci_writel(host, ATMCI_IDR, ~0UL) |
timer_delete_sync(&host->timer) |
dma_release_channel(host->dma.chan) |
free_irq(platform_get_irq(pdev, 0), host) |
| atmci_work_func
| // use host
// devm resources released after |
// remove returns, host is freed |
| // use host (use-after-free)
Fix it by canceling the work after all the sources that can schedule
it (IRQ handler, timeout timer and DMA completion callback) have been
stopped, and before proceeding with the remaining cleanup in
atmci_remove.

sdhci_allocate_bounce_buffer() allocates its buffer with devm_kmalloc()
but maps it with dma_map_single(). The buffer is therefore released by
devres without the streaming DMA mapping being unmapped.
Register a managed action after dma_map_single() succeeds so the mapping
is removed before devres releases the buffer. The action is registered
only for buffers allocated and mapped by the SDHCI core, leaving buffers
provided by host drivers under their existing ownership.

Coverity report INTEGER_OVERFLOW for host->tuning_err.
The tuning_err field in struct sdhci_host is used to store an error
code for re-tuning, but it was declared as unsigned int. Several call
sites store negative error codes into it and later compare against
negative values:
- sdhci.c, sdhci-of-dwcmshc.c and sdhci-pci-gli.c assign it the
return value of __sdhci_execute_tuning()/__sdhci_execute_tuning_9750(),
both of which return a signed int (possibly a negative errno);
- sdhci-of-esdhc.c assigns host->tuning_err = -EAGAIN and later does
"ret = host->tuning_err; if (ret == -EAGAIN ...)";
- sdhci-of-dwcmshc.c prints it with the %d (signed) conversion.
Storing a negative errno in an unsigned int and reading it back as a
signed int only happens to work because of two's-complement, same-width
integer conversions. It is misleading and triggers sign-conversion
warnings. All users treat the value either as a signed error code or as
a boolean (zero / non-zero), so changing the type to a signed int is
safe and makes the intent explicit.

Replace irq_of_parse_and_map() with platform_get_irq_optional() to
get the wake IRQ. This is a more portable approach that works with
both DT and non-DT platforms, and follows the modern platform API
conventions for optional IRQ resources.
The wake IRQ is now fetched earlier in the probe function alongside
the main IRQ, and the -EPROBE_DEFER case is handled properly before
the deferred probe can be triggered.

Disabling the device interrupt and freeing the IRQ prevents new card-detect
work from being queued, but carddet_work already queued by the handler can
still run after via_sd_remove() returns. via_sdc_card_detect() recovers the
host through container_of() and dereferences its MMIO base; once remove()
returns the host can be freed, so that work would touch freed memory.
Cancel carddet_work after freeing the IRQ and before cancelling
finish_bh_work, which the card-detect handler can also queue. carddet_work
can re-enable the interrupt through via_reset_pcictrl(); mask it again
afterwards.
This issue was found by an in-house static analysis tool and confirmed by
manual code review.

request_irq() registers the SD card-detect interrupt and the probe enables
it before mmc_add_host() runs. If mmc_add_host() fails, the error path only
unmaps the registers and returns: the interrupt stays registered, so the
handler keeps running against the host once it is freed. via_sdc_isr()
dereferences sdhost and its MMIO base and schedules carddet_work, which
via_sdc_card_detect() also runs against freed memory through its
container_of() dereference.
Add a probe-error path that disables and frees the interrupt and cancels
carddet_work before unmapping. carddet_work can re-enable the device
interrupt via via_reset_pcictrl(), which restores PCIINTCTRL, so mask it
again after cancelling the work.
This issue was found by an in-house static analysis tool and confirmed by
manual code review.

Replace of_address_to_resource() and the following devm_ioremap_resource()
with a single devm_platform_get_and_ioremap_resource() call in
moxart_probe(). This requests the register region and maps it once, which
is equivalent to the previous devm_ioremap_resource() behavior, and drops
the now-redundant separate resource lookup.
Similarly replace irq_of_parse_and_map() with platform_get_irq(), which
returns a negative errno on failure (including -EPROBE_DEFER) instead of
0, and tighten the error check to irq < 0.
Both substitutions are equivalent for a DT-backed platform device. The
remaining OF usage (mmc_of_parse() and the of_device_id table) is covered
by already-included headers, so linux/of_address.h and linux/of_irq.h
are dropped.
No functional change; the MMC register window is requested and mapped
exactly once, so there is no overlapping region claim.
Built for ARM (allmodconfig + CONFIG_MMC_MOXART) with LLVM=1;
drivers/mmc/host/moxart-mmc.o compiles cleanly.

As pointed out by sashiko bot in [0], recent proposed changes to
dma_max_mapping_size() may affect the driver.
While the issue reported may be a false positive, Robin pointed out some
other DMA-related issues in the driver which are addressed here:
- the DMA max mapping size is irrelevant for the programmed IO mode of
operation
- we should not call dma_max_mapping_size() on the MMC host platform
device, but rather the DMA engine device
In addition, it's better to use the device returned from
dmaengine_get_dma_device() for dma_umap_sg() and dma_unmap_sg(), and not
reference the DMA channel device directly.

Check pm_runtime_force_resume() return value in resume. If it fails
(clock enable failure), return immediately since accessing hardware
registers on an unclocked device would cause a kernel panic.
The early return intentionally skips enable_irq() and
sdhci_disable_irq_wakeups() because the IRQ handler reads
SDHCI_INT_STATUS, which would also fault without clocks. The PM runtime
usage counter leak only affects this already-broken device instance and
is an acceptable tradeoff to preserve system stability.
Remove the return value check for mmc_gpio_set_cd_wake(host->mmc, false)
since disable_irq_wake() called internally always returns 0.
Also return 0 explicitly on the success path instead of propagating
stale return values.

drops the usage counter on failure, avoiding the need for a separate

When using WIFI out-of-band wakeup, an "irq xxx: nobody cared" warning
occurs. This happens because the usdhc interrupt is not disabled during
system suspend when device_may_wakeup() returns false.
The sequence of events leading to this issue:
1. System enters suspend without disabling usdhc interrupt
(because device_may_wakeup() returns false for usdhc device)
2. WIFI out-of-band wakeup triggers system resume via GPIO interrupt
3. WIFI sends a Card interrupt before usdhc has fully resumed
4. usdhc is still in runtime suspend state and cannot handle the
interrupt properly
5. The unhandled interrupt triggers "nobody cared" warning
Fix this by unconditionally disabling the usdhc interrupt during suspend
and re-enabling it during resume, regardless of the wakeup capability.
This ensures no interrupts are processed during the suspend/resume
transition.

SDIO devices such as WiFi may keep power during suspend, so the MMC
core skips full card re-initialization on resume and directly restores
the host controller's ios timing to match the card. For DDR mode,
pm_runtime_force_resume() sets DDR_EN before the pin configuration is
restored from sleep state.
This is related to the SoC IP integration: switching pinctrl setting
(changing alt from GPIO to USDHC) impacts the internal loopback path.
If pinctrl configures the pad to GPIO function, once DDR_EN is set, the
DLL delay will be fixed based on the GPIO function loopback path. When
the pinctrl is later changed to USDHC function, the internal loopback
path changes, making the original fixed sample point no longer suitable
for the current loopback path. This causes persistent read CRC errors on
subsequent data transfers.
SD/eMMC running in DDR mode are unaffected as they are fully
re-initialized from legacy timing after resume.
Fix this by restoring the pinctrl state based on current timing mode
using esdhc_change_pinstate() before pm_runtime_force_resume(). This
ensures the correct pin configuration (e.g., 100/200MHz for UHS modes)
is applied before DDR_EN is set. Only restore for non-wakeup devices
since wakeup devices kept their active pin state during suspend.

esdhc_change_pinstate() checks for pins_100mhz and pins_200mhz at the
top of the function and returns -EINVAL if either is not defined. This
prevents the default case from ever being reached, which means devices
with a sleep pinctrl state but without high-speed pin states (100mhz/
200mhz) can never restore their default pin configuration.
Move the IS_ERR checks for pins_100mhz and pins_200mhz into their
respective switch cases.

sdhci_esdhc_imx_hwinit() unconditionally clears ESDHC_DLL_CTRL by
writing zero. For SDIO devices that keep power during system suspend
and operate in DDR mode, the card remains in DDR timing while the host
DLL override configuration is lost.
Extract the DLL override setup from esdhc_set_uhs_signaling() into
a helper esdhc_set_dll_override(), and call it on the resume path
when the card kept power and is using a DDR timing mode.

tuning save/restore
The tuning save/restore during system PM is conditioned on
mmc_card_wake_sdio_irq(), but this check is unrelated to whether
tuning values need to be preserved. The actual requirement is that
the card keeps power during suspend and the controller is a uSDHC.
SDIO devices using out-of-band GPIO wakeup maintain power during
suspend but do not set the SDIO IRQ wake flag. In this case the
tuning delay values are not saved/restored.
Remove the unnecessary mmc_card_wake_sdio_irq() condition from both
the suspend save and resume restore paths.

Some Realtek USB SD readers with a tray keep raw SD_CD asserted
when an empty tray is inserted. The MMC core then repeatedly tries to
initialize non-existent media, sees command timeouts, calls ->get_cd()
again, and starts the same detect cycle over.
Do not qualify media by open-coding MMC commands in ->get_cd().
Instead, let the normal MMC rescan path probe the card. If an
initialization command times out before a card has been attached,
suppress the raw SD_CD signal so the host can settle and the USB
parent can autosuspend.
Clear the suppression only when raw SD_CD drops. On the affected tray
reader, changing media requires removing and reinserting the tray, so
a low CD transition is the signal that a new insertion attempt can be
trusted again.

vub300_cmndwork_thread() holds cmd_mutex while it sends a command and
waits for the command response. If the response wait times out,
__vub300_command_response() kills the command URBs and then synchronously
resets the USB device through usb_reset_device().
That reset path re-enters the driver through vub300_pre_reset(), which
also takes cmd_mutex. The worker therefore tries to acquire the same
mutex recursively while it is still holding it from the command path.
This issue was found by our static analysis tool and then manually
reviewed against the current tree.
The grounded PoC kept the real worker and timeout/reset carrier:
vub300_cmndwork_thread()
__vub300_command_response()
usb_lock_device_for_reset()
usb_reset_device()
vub300_pre_reset()
Lockdep reported the same-task recursive acquisition on cmd_mutex:
WARNING: possible recursive locking detected
... (&test_vub300.cmd_mutex) ... at: usb_reset_device... [vuln_msv]
... (&test_vub300.cmd_mutex) ... at: vub300_cmndwork_thread+0x12/0x20 [vuln_msv]

*** DEADLOCK ***
Return a flag from __vub300_command_response() when the timeout path needs
a device reset, then perform the reset after vub300_cmndwork_thread() has
cleared the in-flight command state and dropped cmd_mutex. The reset is
still attempted before mmc_request_done(), preserving the existing request
completion ordering while avoiding the recursive lock.

The vub300 driver lifetime-manages its controller state using
vub300->kref, with vub300_delete() freeing the mmc host when the last
reference is dropped. The probe error path after the inactivity timer has
been armed still bypasses that lifetime rule, however, and falls through
to mmc_free_host() directly if mmc_add_host() fails.
The race window is between arming the inactivity timer and reaching the
probe error unwind after mmc_add_host() fails:
probe thread timer/workqueue
------------ ---------------
kref_init(&vub300->kref) ref = 1
kref_get(&vub300->kref) ref = 2, timer ref
add_timer(inactivity_timer) fires after one second
|
| race window
|<---------------------------------------------------->
|
mmc_add_host(mmc)
inactivity timer fires
vub300_queue_dead_work()
kref_get() ref = 3
queue_work(deadwork)
mmc_add_host() fails
timer_delete_sync()
mmc_free_host(mmc)
frees vub300
deadwork runs
use-after-free
The inactivity timeout is one second, so this would require
mmc_add_host() to both fail and take more than one second to do so. This
is unlikely to happen in practice, but the error path is still wrong.
timer_delete_sync() only waits for the timer callback itself. It does
not flush deadwork that the callback may already have queued. As a
result, queued deadwork can still hold a kref while the probe error path
directly frees the backing mmc host, including the vub300 storage.
Fix this by using the same lifetime mechanism as disconnect. Clear
vub300->interface so that the timer callback and any queued deadwork
return early and drop their references, then drop the initial probe
reference and return without falling through to err_free_host.

The implementation of the readX() and writeX() family of IO access
functions is non-standard on ColdFire platforms. They check the supplied
IO address and will return either big or little endian results based on
that check. This is non-standard, they are expected to always return
little-endian byte ordered data. Unfortunately this behavior also means
that ioreadX()/iowroteX() and their big-endian counter parts
ioreadXbe()/iowriteXbe() are wrong. This is now in the process of being
cleaned up and fixed.
Change the use of the readX() and writeX() access functions in this driver
to use the recently defined specific ColdFire internal SoC hardware IO
access functions mcf_read8()/mcf_read16()/mcf_read32() and
mcf_write8()/mcf_write16()/mcf_write32().
There is no functional change to the driver. Though it does have the
effect of making the IO access slightly more efficient, since there is
no longer a need to do the address check at every register access.

Fix logic issues introduced by the kzalloc_flex() conversion in
mmc_test_alloc_mem() due to interaction with the __counted_by

Bounds-checking sanitizers rely on the counter field reflecting the
allocated array size before any array access occurs. However, use
mem->cnt both as the allocation size and as the runtime insertion
index, causing incorrect indexing and potentially invalid bounds
tracking.
Initialize mem->cnt to the maximum allocated number of segments
immediately after kzalloc_flex(), then use a separate local index
variable to track successfully allocated entries. Update mem->cnt to
the actual number of initialized elements before returning or entering
the cleanup path.
Also rewrite mmc_test_free_mem() to use a forward for-loop, improving
readability and ensuring only initialized entries are freed.

would cause the prepare/enable counter imbalance. Also, the same problem
can happen in the driver's suspend() method; note that the resume() method
does check the clk_prepare_enable()'s result -- let's be consistent and do
that in probe() method as well. BTW, I don't know for sure what does the
bus clock control -- if it affects the register accesses, the driver will
likely cause (e.g. on ARM) a kernel oops if it fails to prepare/enable the
bus clock in the probe() method...
