git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext Pull sched_ext fixes from Tejun Heo: - When sched_ext is in bypass mode (e.g. while disabling the BPF scheduler), it was using one DSQ to implement global FIFO scheduling as all it has to do is guaranteeing reasonable forward progress. On multi-socket machines, this can lead to live-lock conditions under certain workloads. Fixed by splitting the queue used for FIFO scheduling per NUMA node. This required several preparation patches. - Hotplug tests on powerpc could reliably trigger deadlock while enabling a BPF scheduler. This was caused by cpu_hotplug_lock nesting inside scx_fork_rwsem and then CPU hotplug path trying to fork a new thread while holding cpu_hotplug_lock. Fixed by restructuring locking in enable and disable paths so that the two locks are not coupled. This required several preparation patches which also fixed a couple other issues in the enable path. - A build fix for !CONFIG_SMP - Userspace tooling sync and updates * tag 'sched_ext-for-6.12-rc1-fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext: sched_ext: Remove redundant p->nr_cpus_allowed checker sched_ext: Decouple locks in scx_ops_enable() sched_ext: Decouple locks in scx_ops_disable_workfn() sched_ext: Add scx_cgroup_enabled to gate cgroup operations and fix scx_tg_online() sched_ext: Enable scx_ops_init_task() separately sched_ext: Fix SCX_TASK_INIT -> SCX_TASK_READY transitions in scx_ops_enable() sched_ext: Initialize in bypass mode sched_ext: Remove SCX_OPS_PREPPING sched_ext: Relocate check_hotplug_seq() call in scx_ops_enable() sched_ext: Use shorter slice while bypassing sched_ext: Split the global DSQ per NUMA node sched_ext: Relocate find_user_dsq() sched_ext: Allow only user DSQs for scx_bpf_consume(), scx_bpf_dsq_nr_queued() and bpf_iter_scx_dsq_new() scx_flatcg: Use a user DSQ for fallback instead of SCX_DSQ_GLOBAL tools/sched_ext: Receive misc updates from SCX repo sched_ext: Add __COMPAT helpers for features added during v6.12 devel cycle sched_ext: Build fix for !CONFIG_SMP

Commit d2aaf1996504 ("ACPI: resource: Add DMI quirks for ASUS Vivobook E1504GA and E1504GAB") does exactly what the subject says, adding DMI matches for both the E1504GA and E1504GAB.

__fatal_error routine doesn't check strerror_r() return value, which results in the following compile time warning: posix_timers.c: In function ‘__fatal_error’: posix_timers.c:31:9: warning: ignoring return value of ‘strerror_r’ declared with attribute ‘warn_unused_result’ [-Wunused-result] 31 | strerror_r(errno, buf, sizeof(buf)); Fix this by adding a check for return value and error handling appropriate for the GNU-specific strerror_r() in use in __fatal_error(). Check if return string is null and handle accordingly. From Linux strerror_r() manual page: "The GNU-specific strerror_r() returns a pointer to a string containing the error message. This may be either a pointer to a string that the function stores in buf, or a pointer to some (immutable) static string (in which case buf is unused). If the function stores a string in buf, then at most buflen bytes are stored (the string may be truncated if buflen is too small and errnum is unknown). The string always includes a terminating null byte."

2024-09-30io_uring/net: harden multishot termination case for recvJens Axboe
If the recv returns zero, or an error, then it doesn't matter if more data has already been received for this buffer. A condition like that should terminate the multishot receive. Rather than pass in the collected return value, pass in whether to terminate or keep the recv going separately. Note that this isn't a bug right now, as the only way to get there is via setting MSG_WAITALL with multishot receive. And if an application does that, then -EINVAL is returned anyway. But it seems like an easy bug to introduce, so let's make it a bit more explicit.

2024-09-30EINJ, CXL: Fix CXL device SBDF calculationBen Cheatham
The SBDF of the target CXL 2.0 compliant root port is required to inject a CXL protocol error as per ACPI 6.5. The SBDF given has to be in the following format: 31 24 23 16 15 11 10 8 7 0 +-------------------------------------------------+ | segment | bus | device | function | reserved | +-------------------------------------------------+ The SBDF calculated in cxl_dport_get_sbdf() doesn't account for the reserved bits currently, causing the wrong SBDF to be used. Fix said calculation to properly shift the SBDF. Without this fix, error injection into CXL 2.0 root ports through the CXL debugfs interface (<debugfs>/cxl) is broken. Injection through the legacy interface (<debugfs>/apei/einj/) will still work because the SBDF is manually provided by the user.

On a few platforms such as TI's AM69 device, disable_irq() fails to keep track of the interrupts that happen between disable_irq() and enable_irq() and those interrupts are missed. Use the ->irq_unmask() and ->irq_mask() methods instead of ->irq_enable() and ->irq_disable() to correctly keep track of edges when disable_irq is called.

2024-09-30kconfig: fix infinite loop in sym_calc_choice()Masahiro Yamada
Since commit f79dc03fe68c ("kconfig: refactor choice value calculation"), Kconfig for ARCH=powerpc may result in an infinite loop. This occurs because there are two entries for POWERPC64_CPU in a choice block. If the same symbol appears twice in a choice block, the ->choice_link node is added twice to ->choice_members, resulting a corrupted linked list. A simple test case is: choice prompt "choice" config A bool "A" config B bool "B 1" config B bool "B 2" endchoice Running 'make defconfig' results in an infinite loop. One solution is to replace the current two entries: config POWERPC64_CPU bool "Generic (POWER5 and PowerPC 970 and above)" depends on PPC_BOOK3S_64 && !CPU_LITTLE_ENDIAN select PPC_64S_HASH_MMU config POWERPC64_CPU bool "Generic (POWER8 and above)" depends on PPC_BOOK3S_64 && CPU_LITTLE_ENDIAN select ARCH_HAS_FAST_MULTIPLIER select PPC_64S_HASH_MMU select PPC_HAS_LBARX_LHARX with the following single entry: config POWERPC64_CPU bool "Generic 64 bit powerpc" depends on PPC_BOOK3S_64 select ARCH_HAS_FAST_MULTIPLIER if CPU_LITTLE_ENDIAN select PPC_64S_HASH_MMU select PPC_HAS_LBARX_LHARX if CPU_LITTLE_ENDIAN In my opinion, the latter looks cleaner, but PowerPC maintainers may prefer to display different prompts depending on CPU_LITTLE_ENDIAN. For now, this commit fixes the issue in Kconfig, restoring the original behavior. I will reconsider whether such a use case is worth supporting.

2024-09-30kbuild: move non-boot built-in DTBs to .rodata sectionMasahiro Yamada
Commit aab94339cd85 ("of: Add support for linking device tree blobs into vmlinux") introduced a mechanism to embed DTBs into vmlinux. Initially, it was used for wrapping boot DTBs in arch/*/boot/dts/, but it is now reused for more generic purposes, such as testing. Built-in DTBs are discarded because KERNEL_DTB() is part of INIT_DATA, as defined in include/asm-generic/vmlinux.lds.h. This has not been an issue so far because OF unittests are triggered during boot, as defined by late_initcall(of_unittest). However, the recent clk KUnit test additions have caused problems because KUnit can execute test suites after boot. For example: # echo > /sys/kernel/debug/kunit/clk_register_clk_parent_data_device/run This command triggers a stack trace because built-in DTBs have already been freed. While it is possible to move such test suites from kunit_test_suites to kunit_test_init_section_suites, it would be preferable to avoid usage limitations. This commit moves non-boot built-in DTBs to the .rodata section. Since these generic DTBs are looked up by name, they do not need to be placed in the special .dtb.init.rodata section. Boot DTBs should remain in .dtb.init.rodata because the arch boot code generally does not know the DT name, thus it uses the __dtb_start symbol to locate it. This separation also ensures that the __dtb_start symbol references the boot DTB. Currently, the .dtb.init.rodata is a mixture of both boot and non-boot DTBs. The __dtb_start symbol must be followed by the boot DTB, but we currently rely on the link order (i.e., the order in Makefiles), which is very fragile. The implementation is kind of cheesy; the section is .dtb.init.rodata when $(obj) starts with arch/$(SRCARCH)/boot/dts, and .rodata section otherwise. This will be refactored later.

To avoid these warnings, remove the CONFIG_PM ifdef guard and use the RUNTIME_PM_OPS macro to ensure these functions always appear used to the compiler, which allows the references to the arrays to be visible as well. This results in no difference in runtime behavior because bmi323_core_pm_ops is only used when CONFIG_PM is set with the pm_ptr() macro.

2024-09-30iio: light: opt3001: add missing full-scale range valueEmil Gedenryd
The opt3001 driver uses predetermined full-scale range values to determine what exponent to use for event trigger threshold values. The problem is that one of the values specified in the datasheet is missing from the implementation. This causes larger values to be scaled down to an incorrect exponent, effectively reducing the maximum settable threshold value by a factor of 2. Add missing full-scale range array value.

2024-09-30iio: light: veml6030: fix IIO device retrieval from embedded deviceJavier Carrasco
The dev pointer that is received as an argument in the in_illuminance_period_available_show function references the device embedded in the IIO device, not in the i2c client. dev_to_iio_dev() must be used to accessthe right data. The current implementation leads to a segmentation fault on every attempt to read the attribute because indio_dev gets a NULL assignment. This bug has been present since the first appearance of the driver, apparently since the last version (V6) before getting applied. A constant attribute was used until then, and the last modifications might have not been tested again.

handling. In the current implementation, the local variable field_value is used without prior initialization, which may lead to reading uninitialized memory. Specifically, in the macro set_mask_bits, the initial (potentially uninitialized) value of the buffer is copied into old__, and a mask is applied to calculate new__.

2024-09-29close_range(): fix the logics in descriptor table trimmingAl Viro
Cloning a descriptor table picks the size that would cover all currently opened files. That's fine for clone() and unshare(), but for close_range() there's an additional twist - we clone before we close, and it would be a shame to have close_range(3, ~0U, CLOSE_RANGE_UNSHARE) leave us with a huge descriptor table when we are not going to keep anything past stderr, just because some large file descriptor used to be open before our call has taken it out. Unfortunately, it had been dealt with in an inherently racy way - sane_fdtable_size() gets a "don't copy anything past that" argument (passed via unshare_fd() and dup_fd()), close_range() decides how much should be trimmed and passes that to unshare_fd(). The problem is, a range that used to extend to the end of descriptor table back when close_range() had looked at it might very well have stuff grown after it by the time dup_fd() has allocated a new files_struct and started to figure out the capacity of fdtable to be attached to that. That leads to interesting pathological cases; at the very least it's a QoI issue, since unshare(CLONE_FILES) is atomic in a sense that it takes a snapshot of descriptor table one might have observed at some point. Since CLOSE_RANGE_UNSHARE close_range() is supposed to be a combination of unshare(CLONE_FILES) with plain close_range(), ending up with a weird state that would never occur with unshare(2) is confusing, to put it mildly. It's not hard to get rid of - all it takes is passing both ends of the range down to sane_fdtable_size(). There we are under ->files_lock, so the race is trivially avoided. So we do the following: * switch close_files() from calling unshare_fd() to calling dup_fd(). * undo the calling convention change done to unshare_fd() in 60997c3d45d9 "close_range: add CLOSE_RANGE_UNSHARE" * introduce struct fd_range, pass a pointer to that to dup_fd() and sane_fdtable_size() instead of "trim everything past that point" they are currently getting. NULL means "we are not going to be punching any holes"; NR_OPEN_MAX is gone. * make sane_fdtable_size() use find_last_bit() instead of open-coding it; it's easier to follow that way. * while we are at it, have dup_fd() report errors by returning ERR_PTR(), no need to use a separate int *errorp argument.

Maybe we could instead have made the call sites conditional, since the callers (kvm_arch_{en,dis}able_virtualization()) have an empty weak fallback.
