Pass union tls_crypto_context pointer, rather than struct tls_crypto_info pointer, to memzero_explicit(). The address of the pointer is the same before and after. But the new construct means that the size of the dereferenced pointer type matches the size being zeroed. Which aids static analysis.

2024-07-09spi: mux: set ctlr->bits_per_word_maskDavid Lechner
Like other SPI controller flags, bits_per_word_mask may be used by a peripheral driver, so it needs to reflect the capabilities of the underlying controller. Signed-off-by: David Lechner <dlechner@baylibre.com> Link: https://patch.msgid.link/20240708-spi-mux-fix-v1-3-6c8845193128@baylibre.com Signed-off-by: Mark Brown <broonie@kernel.org>
2024-07-09spi: add defer_optimize_message controller flagDavid Lechner
Adding spi_optimize_message() broke the spi-mux driver because it calls spi_async() from it's transfer_one_message() callback. This resulted in passing an incorrectly optimized message to the controller. For example, if the underlying controller has an optimize_message() callback, this would have not been called and can cause a crash when the underlying controller driver tries to transfer the message. Also, since the spi-mux driver swaps out the controller pointer by replacing msg->spi, __spi_unoptimize_message() was being called with a different controller than the one used in __spi_optimize_message(). This could cause a crash when attempting to free the message resources when __spi_unoptimize_message() is called in spi_finalize_current_message() since it is being called with a controller that did not allocate the resources. This is fixed by adding a defer_optimize_message flag for controllers. This flag causes all of the spi_[maybe_][un]optimize_message() calls to be a no-op (other than attaching a pointer to the spi device to the message). This allows the spi-mux driver to pass an unmodified message to spi_async() in spi_mux_transfer_one_message() after the spi device has been swapped out. This causes __spi_optimize_message() and __spi_unoptimize_message() to be called only once per message and with the correct/same controller in each case.

2024-07-09spi: don't unoptimize message in spi_async()David Lechner
Calling spi_maybe_unoptimize_message() in spi_async() is wrong because the message is likely to be in the queue and not transferred yet. This can corrupt the message while it is being used by the controller driver. spi_maybe_unoptimize_message() is already called in the correct place in spi_finalize_current_message() to balance the call to spi_maybe_optimize_message() in spi_async().

2024-07-09thermal: intel: hfi: Give HFI instances package scopeZhang Rui
The Intel Software Developer's Manual defines the scope of HFI (registers and memory buffer) as a package. Use package scope(*) in the software representation of an HFI instance. Using die scope in HFI instances has the effect of creating multiple conflicting instances for the same package: each instance allocates its own memory buffer and configures the same package-level registers. Specifically, only one of the allocated memory buffers can be set in the MSR_IA32_HW_FEEDBACK_PTR register. CPUs get incorrect HFI data from the table. The problem does not affect current HFI-capable platforms because they all have single-die processors. (*) We used die scope for HFI instances because there had been processors with packages enumerated as dies. None of those systems supported HFI, though. If such a system emerged, it would need to be quirked.

Similar to other Asus Vivobooks, the Asus Vivobook Pro N6506MJ has a DSDT table that describes IRQ 1 as ActiveLow, whereas the kernel overrides it to Edge_High. This discrepancy prevents the internal keyboard from functioning properly. This patch resolves this issue by adding this laptop to the override table that prevents the kernel from overriding this IRQ.

2024-07-09USB: serial: mos7840: fix crash on resumeDmitry Smirnov
Since commit c49cfa917025 ("USB: serial: use generic method if no alternative is provided in usb serial layer"), USB serial core calls the generic resume implementation when the driver has not provided one. This can trigger a crash on resume with mos7840 since support for multiple read URBs was added back in 2011. Specifically, both port read URBs are now submitted on resume for open ports, but the context pointer of the second URB is left set to the core rather than mos7840 port structure. Fix this by implementing dedicated suspend and resume functions for mos7840. Tested with Delock 87414 USB 2.0 to 4x serial adapter.

Last email from Tsahee Zidenberg was in 2016 [1], so move Tsahee from Amazon platform maintainers to credits (thank you for your contributions and maintenance!). Stale maintainer entries hide information whether subsystem needs help, has a bus-factor or is even orphaned. The Amazon platform still has active maintainer - Antoine Tenart - however there was no maintenance activities coming from Antoine. All my patches from last 4 years related to Amazon remained unanswered - no acks, no picks - so document the actual not active status of the platform by changing it to Odd Fixes.

2024-07-09platform/x86: hp-wmi: Fix platform profile option switch bug on Omen and ↵Alexis Belmonte
Victus laptops Fix a platform profile option switch/getter bug on some Omen and Victus laptops dismissing userspace choice when selecting performance mode in inadequate conditions (e.g. by being disconnected from the AC power plug) by - hooking an ACPI notify handler through the omen_register_powersource_event_handler method that listens to AC power source changes (plugging in/out the AC power plug) - keeping an intermediate active_platform_profile variable that is set when userspace changes the platform profile setting - restoring the selected platform profile kept in active_platform_profile when AC power is plugged back into the laptop through the power_supply_is_system_supplied call check, unless if the user decided to alter the platform profile mid-way Add a dependency to the POWER_SUPPLY subsystem to be able to check for power_supply_is_system_supplied. Introduce intermediary functions to leverage platform profile <-> internal thermal profile translation code from platform_profile_omen_set and callers. These changes makes the module compliant with the principles defined in the Platform Profile Selection page of the Kernel documentation on those kind of laptops; which is to not "(...) let userspace know about any sub-optimal conditions which are impeding reaching the requested performance level". Since the Omen and Victus laptops share the same embedded controller system, the fix is applicable to both categories of laptops.
