2023-01-13spi: SPI core CS delay fixes and additionsMark Brown
Merge series from Hector Martin <marcan@marcan.st>: Commits f6c911f3308c ("spi: dt-bindings: Introduce spi-cs-setup-ns property") and 33a2fde5f77b ("spi: Introduce spi-cs-setup-ns property") introduced a new property to represent the CS setup delay in the device tree, but they have some issues: - The property is only parsed as a 16-bit integer number of nanoseconds, which limits the maximum value to ~65us. This is not a reasonable upper limit, as some devices might need a lot more. - The property name is inconsistent with other delay properties, which use a "*-delay-ns" naming scheme. - Only the setup delay is introduced, but not the related hold and inactive delay times. This series fixes the issues and adds support for the two missing properties. Please pull in the first 3 patches as fixes for 6.2, to avoid introducing a problematic DT API in this release. The last two patches can wait until 6.3, though are probably harmless to throw in as fixes too, since they're trivial.

2023-01-13spi: Use a 32-bit DT property for spi-cs-setup-delay-nsJanne Grunau
65us is not a reasonable maximum for this property, as some devices might need a much longer setup time (e.g. those driven by firmware on the other end). Plus, device tree property values are in 32-bit cells and smaller widths should not be used without good reason. Also move the logic to a helper function, since this will later be used to parse other CS delay properties too.

2023-01-11spi: spidev: remove debug messages that access spidev->spi without lockingBartosz Golaszewski
The two debug messages in spidev_open() dereference spidev->spi without taking the lock and without checking if it's not null. This can lead to a crash.

2023-01-11spi: spidev: fix a race condition when accessing spidev->spiBartosz Golaszewski
There's a spinlock in place that is taken in file_operations callbacks whenever we check if spidev->spi is still alive (not null). It's also taken when spidev->spi is set to NULL in remove(). This however doesn't protect the code against driver unbind event while one of the syscalls is still in progress. To that end we need a lock taken continuously as long as we may still access spidev->spi. As both the file ops and the remove callback are never called from interrupt context, we can replace the spinlock with a mutex.

2023-01-03spi: pl022: Only use DT-specified DMA channelsVincent Whitchurch
When a platform is booted with devicetree and does not provide a platform data structure, the driver creates one internally. enable_dma should not be set in this structure when creating it; the probe function will set it later if DMA channels are specified via the devicetree. Setting enable_dma = 1 when creating this internal platform data can lead to pl022_dma_probe() finding bogus DMA channels (since there is no channel filter specified) when no DMA channels are specified in the devicetree.

2022-12-25treewide: Convert del_timer*() to timer_shutdown*()Steven Rostedt (Google)
Due to several bugs caused by timers being re-armed after they are shutdown and just before they are freed, a new state of timers was added called "shutdown". After a timer is set to this state, then it can no longer be re-armed. The following script was run to find all the trivial locations where del_timer() or del_timer_sync() is called in the same function that the object holding the timer is freed. It also ignores any locations where the timer->function is modified between the del_timer*() and the free(), as that is not considered a "trivial" case. This was created by using a coccinelle script and the following commands: $ cat timer.cocci @@ expression ptr, slab; identifier timer, rfield; @@ ( - del_timer(&ptr->timer); + timer_shutdown(&ptr->timer); | - del_timer_sync(&ptr->timer); + timer_shutdown_sync(&ptr->timer); ) ... when strict when != ptr->timer ( kfree_rcu(ptr, rfield); | kmem_cache_free(slab, ptr); | kfree(ptr); ) $ spatch timer.cocci . > /tmp/t.patch $ patch -p1 < /tmp/t.patch Link: https://lore.kernel.org/lkml/20221123201306.823305113@linutronix.de/ Signed-off-by: Steven Rostedt (Google) <rostedt@goodmis.org> Acked-by: Pavel Machek <pavel@ucw.cz> [ LED ] Acked-by: Kalle Valo <kvalo@kernel.org> [ wireless ] Acked-by: Paolo Abeni <pabeni@redhat.com> [ networking ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2022-12-23pstore: Properly assign mem_type propertyLuca Stefani
If mem-type is specified in the device tree it would end up overriding the record_size field instead of populating mem_type. As record_size is currently parsed after the improper assignment with default size 0 it continued to work as expected regardless of the value found in the device tree. Simply changing the target field of the struct is enough to get mem-type working as expected.

2022-12-23pstore: Make sure CONFIG_PSTORE_PMSG selects CONFIG_RT_MUTEXESJohn Stultz
In commit 76d62f24db07 ("pstore: Switch pmsg_lock to an rt_mutex to avoid priority inversion") I changed a lock to an rt_mutex. However, its possible that CONFIG_RT_MUTEXES is not enabled, which then results in a build failure, as the 0day bot detected: https://lore.kernel.org/linux-mm/202212211244.TwzWZD3H-lkp@intel.com/ Thus this patch changes CONFIG_PSTORE_PMSG to select CONFIG_RT_MUTEXES, which ensures the build will not fail.

2022-12-23cfi: Fix CFI failure with KASANSami Tolvanen
When CFI_CLANG and KASAN are both enabled, LLVM doesn't generate a CFI type hash for asan.module_ctor functions in translation units where CFI is disabled, which leads to a CFI failure during boot when do_ctors calls the affected constructors: CFI failure at do_basic_setup+0x64/0x90 (target: asan.module_ctor+0x0/0x28; expected type: 0xa540670c) Specifically, this happens because CFI is disabled for kernel/cfi.c. There's no reason to keep CFI disabled here anymore, so fix the failure by not filtering out CC_FLAGS_CFI for the file. Note that https://reviews.llvm.org/rG3b14862f0a96 fixed the issue where LLVM didn't emit CFI type hashes for any sanitizer constructors, but now type hashes are emitted correctly for TUs that use CFI.
