Char/Misc/IIO/etc driver update for 7.3-rc1
Here is the big set of char, misc, iio, counter, fpga, and other small
driver subsystems for 7.3-rc1.
Overall, due to some driver removals we only added a bit more code than
removed, which was a nice change. Highlights in this merge request are:
- Loads of IIO driver updates and additions
- binder driver updates (more on that below...)
- Removal of the SGI XP and GRU drivers as they are not used anymore
and turn out to be pretty insecure overall
- Removal of the obsolete ibmasm driver as it's not being used anymore
- Coresight driver updates and additions
- Mei driver udpates
- Counter driver updates
- FPGA driver updates
- ICC driver updates
- lots and lots of other tiny driver updates to resolve reported
issues
All of these have been in linux-next for a while, with the only reported
issues being some major merge conflicts. Miguel pointed out some of
these with the Rust tree merge, which is the majority of them. I'll
follow up with a diffstat of the merge resolution I made against your
most recent tree, which works for me.

Pull PCI updates from Bjorn Helgaas:
"Resource management:
- Add hotplug reservation only once (not at each level of the
hierarchy) so bridge windows don't grow more than necessary (Ilpo
Järvinen)
Driver binding:
- Rework device matching so device ID lifetime only needs to cover
the probe path since dynamic IDs can be removed at any time (Gary
Guo)
Error handling:
- Update mappings of AER errors to agent & layer and log them for
each individual error when multiple errors detected (Lukas Wunner)
- Log Error Source only once, not twice in separate messages (Lukas
Wunner)
- Emit TLP Log only for unmasked errors (Lukas Wunner)
- Support Advisory Non-Fatal Errors (Lukas Wunner)
- Allow DPC on all Downstream Ports, not just Root Ports, when OS
controls AER (Darshit Shah)
ASPM:
- Program the same ASPM Control values for every function of
multi-function devices, as recommended by the PCIe spec (Krishna
Chaitanya Chundru)
- Avoid L0s for Realtek RTS525A, where it causes an AER interrupt
storm (Max Lee)
- Avoid ASPM L0s, L1, and L1 PM Substates based on 'aspm-no-l0s',
'aspm-no-l1' [1], and 'aspm-no-l1ss' DT properties (Krishna
Chaitanya Chundru)
Power management:
- Allow D3 for native hotplug-capable Root Ports on non-x86 platforms
(we avoid D3 for these ports on x86 because some old platforms
didn't validate it) (Manivannan Sadhasivam)
- Allow portdrv to claim Ports even if they don't support services
(AER, PME, DPC, hotplug, etc) so it can do power management (Brian
Norris)
Power control:
- Add support for PCIe WAKE# interrupt when described via DT (Krishna
Chaitanya Chundru)
- For the TC9563 PCIe switch:
- Take a reference on the I2C adapter to avoid uninterruptible
hang when unloading an I2C module while in-use (Johan Hovold)
- Update DT binding and driver to restrict Tx Amplitude, DFE and
N_FTS to USP, DSP1 and DSP2 (Manivannan Sadhasivam)
- Power off only external-facing ports (DSP1, DSP2), leaving USP
and DSP3 (aka VDSP) powered up (Manivannan Sadhasivam)
- Move integrated MAC Endpoint out of the list of internal ports
and configure it separately (Manivannan Sadhasivam)
Virtualization:
- Add ACS quirk for Pericom PI7C9X2G608 switches (Tim Harvey)
- Fix a long-standing bug in the Intel PCH Root Port MPC ACS quirk
that didn't update the intended INTEL_MPC_REG_IRBNCE bit because it
used a 16-bit config write when a 32-bit write was intended
(Mohamad Raizudeen)
Procfs:
- Avoid spurious runtime PM wakeup on config space accesses that are
outside config space and fail before reaching PCI (Krzysztof
Wilczyński)
- Warn on user-space writes to kernel-exclusive config space regions,
as we already do for sysfs (Krzysztof Wilczyński)
- Check credentials of opener, not reader, for config space reads, as
we already do for sysfs (Krzysztof Wilczyński)
Sysfs:
- In pci_write_legacy_io(), avoid out-of-bounds reads from the user
buffer and fix incorrect ioport write data (1-byte writes on
little-endian powerpc, 2- and 4-byte writes on big-endian powerpc)
(Krzysztof Wilczyński)
- In pci_read_legacy_io(), fix incorrect ioport read data for 2- and
4-byte reads on big-endian powerpc (Krzysztof Wilczyński)
- Fix I/O port accessor argument order in Alpha pci_legacy_write()
(Krzysztof Wilczyński)
- Avoid spurious runtime PM wakeup on config space accesses that are
outside config space and fail before reaching PCI (Krzysztof
Wilczyński)
- Return -EINVAL, not -ENODEV, for mmap of I/O BAR that fails because
the arch doesn't support it, as we do for procfs (Krzysztof
Wilczyński)
- Check for LOCKDOWN_PCI_ACCESS for legacy_io and legacy_mem, as we
do for other config space accessors (Krzysztof Wilczyński)
Peer-to-peer DMA:
- Add Nvidia Vera Rubin to list of platforms that support P2PDMA
(Leon Romanovsky)
Endpoint framework:
- Check doorbell SUCCESS bit in pci_endpoint_test to avoid treating
some failures as successes (Niklas Cassel)
- Fail doorbell test when the trigger IRQ is missed (Niklas Cassel)
New native PCIe controller drivers:
- Add DT binding and driver for NVIDIA Tegra264 (Thierry Reding)
Native PCIe controllers:
- Use common wait time definitions for PCIe link monitoring instead
of defining driver-private duplicates (Thierry Reding)
Generic host bridge driver:
- Fix NULL pointer dereference that caused enumeration failures on
32-bit CAM systems (Steffen Persvold)
Amlogic Meson PCIe controller driver:
- Correct the PERST# GPIO state so it remains asserted until power
and REFCLK become stable to fix enumeration failure (Ronald
Claveau)
ASPEED PCIe controller driver:
- Switch to irq_domain_create_linear() so we can obsolete
irq_domain_add_linear() (Jiri Slaby)
Cadence PCIe controller driver:

This work is about 3 cycles old and has been in -next for about that time. When the kernel boots init_task creates PID 1 and then kthreadd. From that point every kthread and PID 1 share the same fs_struct. That is why pivot_root() has to rewrite the fs_struct of all kthreads. The rewriting exists so that kthreads can use init's filesystem state when they want to. It also means userspace can move the ground out from under the kernel. PID 1 now gets a completely separate fs_struct. All kthreads are anchored in a private SB_KERNMOUNT instance of nullfs that cannot be mounted on and cannot be used to follow other mounts. Userspace init can no longer affect kthread filesystem state and kthreads can no longer affect userspace fs state without explicit opting in to that. Path lookup from a kthread now fails by default. It makes it deliberately hard to offload security sensitive operations into init's filesystem state from a kthread. Places that legitimately need to look something up there opt in through the new scoped_with_init_fs() which temporarily overrides the caller's fs_struct with init's. usermodehelpers remain the only kernel tasks that genuinely share init's filesystem state, since they execute random binaries in the root filesystem (excellent...).

hwrng: core - Stop/start hwrng_fillfn() kthread before/after suspend-resume
The hwrng_fillfn() kernel thread accesses the RNG device directly. During suspend and resume sequences, hwrng_fillfn() may attempt to access the RNG device while it is suspended. To address this, the hwrng_fillfn() kernel thread is stopped before suspend, and restarted after resume. This is done using the pm_notifier mechanism.

hwrng: imx-rngc - Disable clock on registration failure
The RNGC clock is enabled manually before runtime PM is configured. If
devm_hwrng_register() fails, probe returns without disabling the clock.
The devm_pm_runtime_enable() cleanup only disables runtime PM and does not
call imx_rngc_suspend().
Disable the clock before returning from this failure path.

virtio_console: fix race between hvc put_chars and virtqueue teardown on freeze
With no_console_suspend enabled, hvc console output can continue while virtio_console is freezing. In that window, put_chars can still enqueue buffers to the output virtqueue while virtcons_freeze is tearing queues down, triggering a BUG_ON in virtqueue_detach_unused_buf_split: BUG_ON(vq->vq.num_free != vq->split.vring.num) Add a pm_freezing flag to ports_device. Set it via smp_store_release() at the start of virtcons_freeze(); put_chars() and __send_to_port() drop output while the flag is set, checked via smp_load_acquire(). The check in __send_to_port() is placed under outvq_lock, making it atomic with remove_port_data() which also acquires outvq_lock. Once remove_port_data() returns for a given port, no concurrent __send_to_port() can add buffers before remove_vqs() tears down the vq. After setting pm_freezing, acquire and release outvq_lock for each port (protected by ports_lock to prevent list manipulation races) before calling virtio_reset_device(). A TX thread that already passed the pm_freezing check may still hold outvq_lock while spinning for host acknowledgment; the drain loop ensures all such threads have completed before the device is reset. Clear pm_freezing in virtcons_restore() only after all port->out_vq pointers have been reassigned to the newly allocated virtqueues, preventing TX paths from dereferencing freed vqs during restore.

virtio_console: fix control queue race during restore
In virtcons_restore(), after virtio_device_ready() sets DRIVER_OK, the device becomes active. If the control receive queue (c_ivq) is populated immediately, the host can instantly deliver pending control messages (e.g., VIRTIO_CONSOLE_PORT_REMOVE). This triggers the control_work_handler(), which can modify the portdev->ports list concurrently with the unprotected list_for_each_entry loop in virtcons_restore(), leading to list corruption or Use-After-Free. Fix this by deferring the population of the control receive queue (fill_queue for c_ivq) until after the list iteration is complete. This ensures the host cannot inject control messages during the vulnerable window.

virtio_console: fix hot-unplug races in TX paths
When a port is hot-unplugged, unplug_port() nullifies port->portdev. However, concurrent TX paths (__send_to_port, put_chars) could read a stale pointer or encounter a NULL pointer dereference. Add READ_ONCE(port->portdev) and NULL checks in the TX paths. In __send_to_port(), move the out_vq assignment inside the outvq_lock and check portdev under the lock. Correspondingly, update unplug_port() to NULL out port->portdev while holding the outvq_lock to serialize with __send_to_port(). In put_chars(), return count instead of 0 on unplug to prevent the hvc layer from spinning in an infinite retry loop.

virtio_console: refactor __send_to_port() buffer ownership
Modify __send_to_port() to take ownership of a struct port_buffer * instead of a void * raw buffer. Previously, put_chars() would pass a raw kmemdup'd buffer and free it immediately after __send_to_port() returned. This caused a potential Use-After-Free and data corruption if the virtqueue was shared with nonblocking writers, as virtqueue_get_buf() might return an older completed buffer, causing the newly added buffer to be kfree'd while the host is still DMAing from it. By transferring ownership of the allocated port_buffer to __send_to_port(), we ensure that the exact buffer returned by the host is the one that gets freed, resolving the memory lifecycle mismatch.

find_port_by_vq() returns a raw struct port pointer without taking a reference on it, unlike find_port_by_devt_in_portdev() which does. find_port_by_vq()'s only two callers, in_intr() and out_intr(), run as virtqueue interrupt callbacks, entirely independent of and possibly concurrently with unplug_port(), which itself runs from a workqueue when the host sends a VIRTIO_CONSOLE_PORT_REMOVE control message. unplug_port() removes the port from portdev->ports under ports_lock, then later drops its last reference with kref_put(), freeing it via remove_port(). find_port_by_vq() also walks portdev->ports under ports_lock, so if it finds the port still on the list, the list removal, and therefore the eventual kref_put(), has not happened yet, and taking a reference at that point is always safe. Without doing so, in_intr()/out_intr() can be left holding a pointer to a port that unplug_port() frees on another core before they are done using it. Both triggers are host-controlled as the host decides when to send the PORT_REMOVE control message and when to kick the port's data vq. So a malicious backend could race the two on purpose, without any guest side cooperation. The freed object is a generic kmalloc allocation containing a wait_queue_head_t, which in_intr()/out_intr() pass to wake_up_interruptible() after touching the stale pointer. wake_up_interruptible() invokes a function pointer read out of the wait queue's entries. If the freed slab slot is reclaimed with attacker influenced content before that call, then this is an arbitrary function call primitive rather than just undefined behaviour. Take a reference in find_port_by_vq() while still holding ports_lock, matching find_port_by_devt_in_portdev(), and release it in in_intr() and out_intr() once they are done with the port.

initramfs_test: use test init/exit hooks to override init fs
Most initramfs kunit tests interact with initramfs via
unpack_to_rootfs() and subsequently init_stat(), init_unlink(), etc.
It's cleaner and less error-prone to override current->fs with
userspace_init_fs for all initramfs_test_suite tests.

hwrng: stm32 - Fix runtime PM cleanup on registration failure
stm32_rng_probe() enables autosuspend and runtime PM before registering the
hwrng. If devm_hwrng_register() fails, probe returns with runtime PM left
enabled and autosuspend still selected.
The remove callback also only disables runtime PM and does not undo
pm_runtime_use_autosuspend().
Use devm_pm_runtime_enable() so runtime PM is unwound automatically on
probe failure and driver detach. Since the managed cleanup also disables
runtime PM,drop the remove callback.

char: xilinx_hwicap: unregister class on init errors
hwicap_module_init() registers icap_class before reserving the
character-device region and registering the platform driver. If either
of those later steps fails, the init path must undo the successful class
registration before returning an error.
Route the chrdev registration failure through a class unwind label, and
let the platform-driver registration failure fall through the existing
chrdev unwind before unregistering the class. The normal module exit path
is unchanged.
This issue was identified during our ongoing static-analysis research while
reviewing kernel code.

ppdev: prevent overflow when setting port timeout
PPSETTIME64 supplies the timeval fields as s64 values, but
pp_set_timeout() narrows tv_usec to int and calculates tv_sec * HZ in a
signed long. Large positive values can therefore be truncated or overflow
and install an unintended timeout.
Keep both fields as s64, reject a non-canonical microsecond value, and
use timespec64_to_jiffies() to cap excessively large timeouts at
MAX_JIFFY_OFFSET. This is a behavior change because both PPSETTIME
ioctls could previously accept values with tv_usec >= USEC_PER_SEC.
The validation follows the precedent set by sock_set_timeout().

hwrng: omap - Enable on Renesas RZ/N1D
The Kconfig symbol and associated seem to be badly named as they have nothing OMAP specific but instead refer to Inside Secure Safexcel devices which have been used in many SoCs from different manufacturers (like OMAP, Marvell but also eg. Renesas). The Renesas RZ/N1D features this IP, so add this architecture to the dependency allow list. In practice this dependency list does not seem very relevant and could be entirely dropped, given the fact that this IP has been implemented by many different vendors and seems to be architecture agnostic.

tpm: Make the TPM character devices non-seekable
The TPM character devices expose a sequential command/response
interface, but their open handlers leave FMODE_PREAD and FMODE_PWRITE
enabled.
After a command leaves a response pending, pread(fd, buf, 16, 0x1400)
passes 0x1400 as *off to tpm_common_read(). The transfer length is
bounded by response_length, but the offset is used unchecked when
forming data_buffer + *off. A sufficiently large offset therefore causes
an out-of-bounds heap read through copy_to_user() and, if the copy
succeeds, an out-of-bounds zero-write through the following memset().
Positional I/O does not provide coherent semantics for this interface.
An arbitrary pread offset cannot represent how much of a response has
been consumed sequentially. The write callback always stores a command
at the start of data_buffer, while pwrite() does not update file->f_pos
and can leave the sequential read cursor stale.
Call nonseekable_open() from both open handlers. This removes
FMODE_PREAD and FMODE_PWRITE, causing positional reads and writes to
fail with -ESPIPE before reaching the TPM callbacks, and explicitly
marks the files non-seekable. Normal read() and write() continue to use
the existing sequential f_pos cursor, leaving the response state machine
unchanged.
Tested on Linux 6.12 with KASAN and a swtpm TPM2 device:
- sequential partial reads returned the complete response
- pread() and preadv() with offset 0x1400 returned -ESPIPE
- pwrite() and pwritev() with offset zero returned -ESPIPE
- the pending response remained intact after the rejected operations
- a subsequent normal command/response cycle completed normally
- no KASAN report was produced.

hwrng: omap - Fix probe error path cleanup
omap_rng_probe() enables runtime PM before acquiring and enabling the functional clocks. Several later error paths returned or unwound without undoing all state acquired so far. If pm_runtime_resume_and_get() failed, the driver returned through the generic ioremap error label and left runtime PM enabled. If either clock lookup returned -EPROBE_DEFER, the function returned directly and skipped the runtime PM cleanup; the register clock defer path could also leave the already enabled functional clock prepared. Route these failures through the existing unwind labels so each path only undoes resources that were acquired successfully. Keep the resume failure path limited to pm_runtime_disable(), and use the later labels only after the runtime PM usage count or clocks have been acquired. This issue was identified during our ongoing static-analysis research while reviewing kernel code. Fixes: |

hwrng: xilinx-trng - propagate timeout before any data is read
xtrng_readblock32() polls for 16-byte chunks but returns the number of
bytes read even when the first poll times out. Its caller then treats a
zero return as a short successful read, and partial reads for full
32-byte blocks can make the tail copy use a fixed block offset rather
than the amount already produced.
Return the poll error when no data has been read, preserve partial
positive returns after some data is available, stop the generator on all
collection exits, and append tail bytes at the current output count.

tpm: tpm2-sessions: wait for async KPP completion in tpm_buf_append_salt
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.

tpm: tpm_tis: Add settle time for some TPMs
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. For the Nuvoton TPM used in these machines, add a delay after locality is relinquished.

tpm: tpm_tis: store entire did_vid
The entire 32 bit did_vid is read from the device, but only the 16 bit vendor id portion was stored in the tpm_tis_data structure. Storing the entire value allows the device id to be used to handle quirks. Printing the vid and did in the error case also helps identify problem devices.

tpm_crb: Check ACPI_COMPANION() against NULL during probe
Every platform driver can be forced to match a device that doesn't match
its list of device IDs because of device_match_driver_override(), so
platform drivers that rely on the existence of a device's ACPI companion
object need to verify its presence.
Accordingly, add a requisite ACPI_COMPANION() check against NULL to the
tpm_crb driver.

tpm: tpm_tis_spi: Use wait_woken() in wait_for_tmp_stat()
wait_event_interruptible_timeout() evaluates its condition after setting
the current task state to TASK_INTERRUPTIBLE.
With CONFIG_DEBUG_ATOMIC_SLEEP this triggers a warning when the IRQ wait
path is used:
tpm_tis_status()
tpm_tis_spi_read_bytes()
tpm_tis_spi_transfer_full()
spi_bus_lock()
mutex_lock()
Address this with the following measures:
1. Call wait_tpm_stat_cond() only while tasking is running.
2. Use wait_woken() to wait for changes.

tpm: Initialize name_size_alg for non-NULL name in tpm_buf_append_name()
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.
