[PATCH] usb: cdns3: cdnsp-pci: remove redundant pci_disable_device() call

by Miaoqian Lin

The cdnsp-pci driver uses pcim_enable_device() to enable a PCI device, which means the device will be automatically disabled on driver detach through the managed device framework. The manual pci_disable_device() call in the error path is therefore redundant. Found via static anlaysis and this is similar to commit 99ca0b57e49f ("thermal: intel: int340x: processor: Fix warning during module unload").

[PATCH 0/2] mfd: vexpress: convert the driver to using the new generic GPIO chip API

[PATCH] net/mlx5: HWS, change error flow on matcher disconnect

by Subramaniam, Sujana

From: SujanaSubr <sujana.subramaniam(a)sap.com> [ Upstream commit 1ce840c7a659aa53a31ef49f0271b4fd0dc10296 ] Currently, when firmware failure occurs during matcher disconnect flow, the error flow of the function reconnects the matcher back and returns an error, which continues running the calling function and eventually frees the matcher that is being disconnected. This leads to a case where we have a freed matcher on the matchers list, which in turn leads to use-after-free and eventual crash. This patch fixes that by not trying to reconnect the matcher back when some FW command fails during disconnect. Note that we're dealing here with FW error. We can't overcome this problem. This might lead to bad steering state (e.g. wrong connection between matchers), and will also lead to resource leakage, as it is the case with any other error handling during resource destruction. However, the goal here is to allow the driver to continue and not crash the machine with use-after-free error.

[PATCH v7 00/16] pinctrl: introduce the concept of a GPIO pin function category

by Bartosz Golaszewski

Problem: when pinctrl core binds pins to a consumer device and the pinmux ops of the underlying driver are marked as strict, the pin in question can no longer be requested as a GPIO using the GPIO descriptor API. It will result in the following error: [ 5.095688] sc8280xp-tlmm f100000.pinctrl: pin GPIO_25 already requested by regulator-edp-3p3; cannot claim for f100000.pinctrl:570 [ 5.107822] sc8280xp-tlmm f100000.pinctrl: error -EINVAL: pin-25 (f100000.pinctrl:570) This typically makes sense except when the pins are muxed to a function that actually says "GPIO". Of course, the function name is just a string so it has no meaning to the pinctrl subsystem. We have many Qualcomm SoCs (and I can imagine it's a common pattern in other platforms as well) where we mux a pin to "gpio" function using the `pinctrl-X` property in order to configure bias or drive-strength and then access it using the gpiod API. This makes it impossible to mark the pin controller module as "strict". This series proposes to introduce a concept of a sub-category of pinfunctions: GPIO functions where the above is not true and the pin muxed as a GPIO can still be accessed via the GPIO consumer API even for strict pinmuxers. To that end: we first clean up the drivers that use struct function_desc and make them use the smaller struct pinfunction instead - which is the correct structure for drivers to describe their pin functions with. We also rework pinmux core to not duplicate memory used to store the pinfunctions unless they're allocated dynamically. First: provide the kmemdup_const() helper which only duplicates memory if it's not in the .rodata section. Then rework all pinctrl drivers that instantiate objects of type struct function_desc as they should only be created by pinmux core. Next constify the return value of the accessor used to expose these structures to users and finally convert the pinfunction object within struct function_desc to a pointer and use kmemdup_const() to assign it. With this done proceed to add infrastructure for the GPIO pin function category and use it in Qualcomm drivers. At the very end: make the Qualcomm pinmuxer strict.

[PATCH] fs: quota: create dedicated workqueue for quota_release_work

by Shashank A P

There is a kernel panic due to WARN_ONCE when panic_on_warn is set. This issue occurs when writeback is triggered due to sync call for an opened file(ie, writeback reason is WB_REASON_SYNC). When f2fs balance is needed at sync path, flush for quota_release_work is triggered. By default quota_release_work is queued to "events_unbound" queue which does not have WQ_MEM_RECLAIM flag. During f2fs balance "writeback" workqueue tries to flush quota_release_work causing kernel panic due to MEM_RECLAIM flag mismatch errors. This patch creates dedicated workqueue with WQ_MEM_RECLAIM flag for work quota_release_work. ------------[ cut here ]------------ WARNING: CPU: 4 PID: 14867 at kernel/workqueue.c:3721 check_flush_dependency+0x13c/0x148 Call trace: check_flush_dependency+0x13c/0x148 __flush_work+0xd0/0x398 flush_delayed_work+0x44/0x5c dquot_writeback_dquots+0x54/0x318 f2fs_do_quota_sync+0xb8/0x1a8 f2fs_write_checkpoint+0x3cc/0x99c f2fs_gc+0x190/0x750 f2fs_balance_fs+0x110/0x168 f2fs_write_single_data_page+0x474/0x7dc f2fs_write_data_pages+0x7d0/0xd0c do_writepages+0xe0/0x2f4 __writeback_single_inode+0x44/0x4ac writeback_sb_inodes+0x30c/0x538 wb_writeback+0xf4/0x440 wb_workfn+0x128/0x5d4 process_scheduled_works+0x1c4/0x45c worker_thread+0x32c/0x3e8 kthread+0x11c/0x1b0 ret_from_fork+0x10/0x20 Kernel panic - not syncing: kernel: panic_on_warn set ...

[PATCH] rust: kasan/kbuild: fix missing flags on first build

by Miguel Ojeda

If KASAN is enabled, and one runs in a clean repository e.g.: make LLVM=1 prepare make LLVM=1 prepare Then the Rust code gets rebuilt, which should not happen. The reason is some of the LLVM KASAN `rustc` flags are added in the second run: -Cllvm-args=-asan-instrumentation-with-call-threshold=10000 -Cllvm-args=-asan-stack=0 -Cllvm-args=-asan-globals=1 -Cllvm-args=-asan-kernel-mem-intrinsic-prefix=1 Further runs do not rebuild Rust because the flags do not change anymore. Rebuilding like that in the second run is bad, even if this just happens with KASAN enabled, but missing flags in the first one is even worse. The root issue is that we pass, for some architectures and for the moment, a generated `target.json` file. That file is not ready by the time `rustc` gets called for the flag test, and thus the flag test fails just because the file is not available, e.g.: $ ... --target=./scripts/target.json ... -Cllvm-args=... error: target file "./scripts/target.json" does not exist There are a few approaches we could take here to solve this. For instance, we could ensure that every time that the config is rebuilt, we regenerate the file and recompute the flags. Or we could use the LLVM version to check for these flags, instead of testing the flag (which may have other advantages, such as allowing us to detect renames on the LLVM side). However, it may be easier than that: `rustc` is aware of the `-Cllvm-args` regardless of the `--target` (e.g. I checked that the list printed is the same, plus that I can check for these flags even if I pass a completely unrelated target), and thus we can just eliminate the dependency completely. Thus filter out the target. This does mean that `rustc-option` cannot be used to test a flag that requires the right target, but we don't have other users yet, it is a minimal change and we want to get rid of custom targets in the future. We could only filter in the case `target.json` is used, to make it work in more cases, but then it would be harder to notice that it may not work in a couple architectures.

But it happened a very long time ago (9 years ago), and the addition in the kernel is fairly old too, in 342061ee4ef3 ("kasan: support alloca() poisoning"). I assume it should either be renamed or removed?
