2025-03-07thermal: gov_power_allocator: Add missing NULL pointer checkRafael J. Wysocki
commit ac1f43c03fc91eee53cc95683245350d4d87781e upstream. Commit 0dc23567c206 ("thermal: core: Move lists of thermal instances to trip descriptors") overlooked the case in which the Power Allocator governor attempts to bind to a tripless thermal zone and params->trip_max is NULL in check_power_actors(). No power actors can be found in that case, so check_power_actors() needs to be made return 0 then to restore its previous behavior.

commit 713e788c0e07e185fd44dd581f74855ef149722f upstream. When working on OpenRISC support for restartable sequences I noticed and fixed these two issues with the riscv support bits. 1 The 'inc' argument to RSEQ_ASM_OP_R_DEREF_ADDV was being implicitly passed to the macro. Fix this by adding 'inc' to the list of macro arguments. 2 The inline asm input constraints for 'inc' and 'off' use "er", The riscv gcc port does not have an "e" constraint, this looks to be copied from the x86 port. Fix this by just using an "r" constraint. I have compile tested this only for riscv. However, the same fixes I use in the OpenRISC rseq selftests and everything passes with no issues.

2025-03-07ima: Reset IMA_NONACTION_RULE_FLAGS after post_setattrRoberto Sassu
commit 57a0ef02fefafc4b9603e33a18b669ba5ce59ba3 upstream. Commit 0d73a55208e9 ("ima: re-introduce own integrity cache lock") mistakenly reverted the performance improvement introduced in commit 42a4c603198f0 ("ima: fix ima_inode_post_setattr"). The unused bit mask was subsequently removed by commit 11c60f23ed13 ("integrity: Remove unused macro IMA_ACTION_RULE_FLAGS"). Restore the performance improvement by introducing the new mask IMA_NONACTION_RULE_FLAGS, equal to IMA_NONACTION_FLAGS without IMA_NEW_FILE, which is not a rule-specific flag. Finally, reset IMA_NONACTION_RULE_FLAGS instead of IMA_NONACTION_FLAGS in process_measurement(), if the IMA_CHANGE_ATTR atomic flag is set (after file metadata modification). With this patch, new files for which metadata were modified while they are still open, can be reopened before the last file close (when security.ima is written), since the IMA_NEW_FILE flag is not cleared anymore. Otherwise, appraisal fails because security.ima is missing (files with IMA_NEW_FILE set are an exception).

commit 7fb39882b20c98a9a393c244c86b56ef6933cff8 upstream. In Inline mode, the journal is unused, and journal_sectors is zero. Calculating the journal watermark requires dividing by journal_sectors, which should be done only if the journal is configured. Otherwise, a simple table query (dmsetup table) can cause OOPS. This bug did not show on some systems, perhaps only due to compiler optimization. On my 32-bit testing machine, this reliably crashes with the following: : Oops: divide error: 0000 [#1] PREEMPT SMP : CPU: 0 UID: 0 PID: 2450 Comm: dmsetup Not tainted 6.14.0-rc2+ #959 : EIP: dm_integrity_status+0x2f8/0xab0 [dm_integrity] ...

2025-03-07sched_ext: Fix pick_task_scx() picking non-queued tasks when it's called ↵Tejun Heo
without balance() commit 8fef0a3b17bb258130a4fcbcb5addf94b25e9ec5 upstream. a6250aa251ea ("sched_ext: Handle cases where pick_task_scx() is called without preceding balance_scx()") added a workaround to handle the cases where pick_task_scx() is called without prececing balance_scx() which is due to a fair class bug where pick_taks_fair() may return NULL after a true return from balance_fair(). The workaround detects when pick_task_scx() is called without preceding balance_scx() and emulates SCX_RQ_BAL_KEEP and triggers kicking to avoid stalling. Unfortunately, the workaround code was testing whether @prev was on SCX to decide whether to keep the task running. This is incorrect as the task may be on SCX but no longer runnable. This could lead to a non-runnable task to be returned from pick_task_scx() which cause interesting confusions and failures. e.g. A common failure mode is the task ending up with (!on_rq && on_cpu) state which can cause potential wakers to busy loop, which can easily lead to deadlocks. Fix it by testing whether @prev has SCX_TASK_QUEUED set. This makes @prev_on_scx only used in one place. Open code the usage and improve the comment while at it.

A later callback in the resume path invoked cond_resched() which in turn led to the invocation of the scheduler: __cond_resched+0x21/0x60 down_timeout+0x18/0x60 acpi_os_wait_semaphore+0x4c/0x80 acpi_ut_acquire_mutex+0x3d/0x100 acpi_ns_get_node+0x27/0x60 acpi_ns_evaluate+0x1cb/0x2d0 acpi_rs_set_srs_method_data+0x156/0x190 acpi_pci_link_set+0x11c/0x290 irqrouter_resume+0x54/0x60 syscore_resume+0x6a/0x200 kernel_kexec+0x145/0x1c0 __do_sys_reboot+0xeb/0x240 do_syscall_64+0x95/0x180 This is a long standing problem, which probably got more visible with the recent printk changes. Something does a task wakeup and the scheduler sets the NEED_RESCHED flag. cond_resched() sees it set and invokes schedule() from a completely bogus context. The scheduler enables interrupts after context switching, which causes the above warning at the end. Quite some of the code paths in syscore_suspend()/resume() can result in triggering a wakeup with the exactly same consequences. They might not have done so yet, but as they share a lot of code with normal operations it's just a question of time. The problem only affects the PREEMPT_NONE and PREEMPT_VOLUNTARY scheduling models. Full preemption is not affected as cond_resched() is disabled and the preemption check preemptible() takes the interrupt disabled flag into account. Cure the problem by adding a corresponding check into cond_resched().

2025-03-07rcuref: Plug slowpath race in rcuref_put()Thomas Gleixner
commit b9a49520679e98700d3d89689cc91c08a1c88c1d upstream. Kernel test robot reported an "imbalanced put" in the rcuref_put() slow path, which turned out to be a false positive. Consider the following race: ref = 0 (via rcuref_init(ref, 1)) T1 T2 rcuref_put(ref) -> atomic_add_negative_release(-1, ref) # ref -> 0xffffffff -> rcuref_put_slowpath(ref) rcuref_get(ref) -> atomic_add_negative_relaxed(1, &ref->refcnt) -> return true; # ref -> 0 rcuref_put(ref) -> atomic_add_negative_release(-1, ref) # ref -> 0xffffffff -> rcuref_put_slowpath() -> cnt = atomic_read(&ref->refcnt); # cnt -> 0xffffffff / RCUREF_NOREF -> atomic_try_cmpxchg_release(&ref->refcnt, &cnt, RCUREF_DEAD)) # ref -> 0xe0000000 / RCUREF_DEAD -> return true -> cnt = atomic_read(&ref->refcnt); # cnt -> 0xe0000000 / RCUREF_DEAD -> if (cnt > RCUREF_RELEASED) # 0xe0000000 > 0xc0000000 -> WARN_ONCE(cnt >= RCUREF_RELEASED, "rcuref - imbalanced put()") The problem is the additional read in the slow path (after it decremented to RCUREF_NOREF) which can happen after the counter has been marked RCUREF_DEAD. Prevent this by reusing the return value of the decrement. Now every "final" put uses RCUREF_NOREF in the slow path and attempts the final cmpxchg() to RCUREF_DEAD.

2025-03-07vmlinux.lds: Ensure that const vars with relocations are mapped R/OArd Biesheuvel
commit 68f3ea7ee199ef77551e090dfef5a49046ea8443 upstream. In the kernel, there are architectures (x86, arm64) that perform boot-time relocation (for KASLR) without relying on PIE codegen. In this case, all const global objects are emitted into .rodata, including const objects with fields that will be fixed up by the boot-time relocation code. This implies that .rodata (and .text in some cases) need to be writable at boot, but they will usually be mapped read-only as soon as the boot completes. When using PIE codegen, the compiler will emit const global objects into .data.rel.ro rather than .rodata if the object contains fields that need such fixups at boot-time. This permits the linker to annotate such regions as requiring read-write access only at load time, but not at execution time (in user space), while keeping .rodata truly const (in user space, this is important for reducing the CoW footprint of dynamic executables). This distinction does not matter for the kernel, but it does imply that const data will end up in writable memory if the .data.rel.ro sections are not treated in a special way, as they will end up in the writable .data segment by default. So emit .data.rel.ro into the .rodata segment.

2025-03-07mptcp: reset when MPTCP opts are dropped after joinMatthieu Baerts (NGI0)
commit 8668860b0ad32a13fcd6c94a0995b7aa7638c9ef upstream. Before this patch, if the checksum was not used, the subflow was only reset if map_data_len was != 0. If there were no MPTCP options or an invalid mapping, map_data_len was not set to the data len, and then the subflow was not reset as it should have been, leaving the MPTCP connection in a wrong fallback mode. This map_data_len condition has been introduced to handle the reception of the infinite mapping. Instead, a new dedicated mapping error could have been returned and treated as a special case. However, the commit 31bf11de146c ("mptcp: introduce MAPPING_BAD_CSUM") has been introduced by Paolo Abeni soon after, and backported later on to stable. It better handle the csum case, and it means the exception for valid_csum_seen in subflow_can_fallback(), plus this one for the infinite mapping in subflow_check_data_avail(), are no longer needed. In other words, the code can be simplified there: a fallback should only be done if msk->allow_infinite_fallback is set. This boolean is set to false once MPTCP-specific operations acting on the whole MPTCP connection vs the initial path have been done, e.g. a second path has been created, or an MPTCP re-injection -- yes, possible even with a single subflow. The subflow_can_fallback() helper can then be dropped, and replaced by this single condition. This also makes the code clearer: a fallback should only be done if it is possible to do so. While at it, no need to set map_data_len to 0 in get_mapping_status() for the infinite mapping case: it will be set to skb->len just after, at the end of subflow_check_data_avail(), and not read in between.

The bugged code-path comes from an early optimization: when there are no subflows, the PM should (usually) not send RM_ADDR notifications. The above statement is incorrect, as without locks another process could concurrent create a new subflow and cause the RM_ADDR generation. Additionally the supposed optimization is not very effective even performance-wise, as most mptcp sockets should have at least one subflow: the MPC one. Address the issue removing the buggy code path, the existing "slow-path" will handle correctly even the edge case.

2025-03-07intel_idle: Handle older CPUs, which stop the TSC in deeper C states, correctlyThomas Gleixner
commit c157d351460bcf202970e97e611cb6b54a3dd4a4 upstream. The Intel idle driver is preferred over the ACPI processor idle driver, but fails to implement the work around for Core2 generation CPUs, where the TSC stops in C2 and deeper C-states. This causes stalls and boot delays, when the clocksource watchdog does not catch the unstable TSC before the CPU goes deep idle for the first time. The ACPI driver marks the TSC unstable when it detects that the CPU supports C2 or deeper and the CPU does not have a non-stop TSC. Add the equivivalent work around to the Intel idle driver to cure that.

commit 55f1a5f7c97c3c92ba469e16991a09274410ceb7 upstream. Observed VBUS_OVERRIDE & ID_OVERRIDE might be programmed with unexpected value prior to XUSB PADCTL driver, this could also occur in virtualization scenario. For example, UEFI firmware programs ID_OVERRIDE=GROUNDED to set a type-c port to host mode and keeps the value to kernel. If the type-c port is connected a usb host, below errors can be observed right after usb host mode driver gets probed. The errors would keep until usb role class driver detects the type-c port as device mode and notifies usb device mode driver to set both ID_OVERRIDE and VBUS_OVERRIDE to correct value by XUSB PADCTL driver.

commit 71c49ee9bb41e1709abac7e2eb05f9193222e580 upstream. According to the chip manual, the I2C register access type of Loongson-2K2000/LS7A is "B", so we can only access registers in byte form (readb()/writeb()). Although Loongson-2K0500/Loongson-2K1000 do not have similar constraints, register accesses in byte form also behave correctly. Also, in hardware, the frequency division registers are defined as two separate registers (high 8-bit and low 8-bit), so we just access them directly as bytes.

commit dd1998e243f5fa25d348a384ba0b6c84d980f2b2 upstream. The customer reports that there is a soft lockup issue related to the i2c driver. After checking, the i2c module was doing a tx transfer and the bmc machine reboots in the middle of the i2c transaction, the i2c module keeps the status without being reset. Due to such an i2c module status, the i2c irq handler keeps getting triggered since the i2c irq handler is registered in the kernel booting process after the bmc machine is doing a warm rebooting. The continuous triggering is stopped by the soft lockup watchdog timer. Disable the interrupt enable bit in the i2c module before calling devm_request_irq to fix this issue since the i2c relative status bit is read-only. Here is the soft lockup log.

2025-03-07block: Remove zone write plugs when handling native zone append writesDamien Le Moal
commit a6aa36e957a1bfb5341986dec32d013d23228fe1 upstream. For devices that natively support zone append operations, REQ_OP_ZONE_APPEND BIOs are not processed through zone write plugging and are immediately issued to the zoned device. This means that there is no write pointer offset tracking done for these operations and that a zone write plug is not necessary. However, when receiving a zone append BIO, we may already have a zone write plug for the target zone if that zone was previously partially written using regular write operations. In such case, since the write pointer offset of the zone write plug is not incremented by the amount of sectors appended to the zone, 2 issues arise: 1) we risk leaving the plug in the disk hash table if the zone is fully written using zone append or regular write operations, because the write pointer offset will never reach the "zone full" state. 2) Regular write operations that are issued after zone append operations will always be failed by blk_zone_wplug_prepare_bio() as the write pointer alignment check will fail, even if the user correctly accounted for the zone append operations and issued the regular writes with a correct sector. Avoid these issues by immediately removing the zone write plug of zones that are the target of zone append operations when blk_zone_plug_bio() is called. The new function blk_zone_wplug_handle_native_zone_append() implements this for devices that natively support zone append. The removal of the zone write plug using disk_remove_zone_wplug() requires aborting all plugged regular write using disk_zone_wplug_abort() as otherwise the plugged write BIOs would never be executed (with the plug removed, the completion path will never see again the zone write plug as disk_get_zone_wplug() will return NULL). Rate-limited warnings are added to blk_zone_wplug_handle_native_zone_append() and to disk_zone_wplug_abort() to signal this. Since blk_zone_wplug_handle_native_zone_append() is called in the hot path for operations that will not be plugged, disk_get_zone_wplug() is optimized under the assumption that a user issuing zone append operations is not at the same time issuing regular writes and that there are no hashed zone write plugs. The struct gendisk atomic counter nr_zone_wplugs is added to check this, with this counter incremented in disk_insert_zone_wplug() and decremented in disk_remove_zone_wplug(). To be consistent with this fix, we do not need to fill the zone write plug hash table with zone write plugs for zones that are partially written for a device that supports native zone append operations. So modify blk_revalidate_seq_zone() to return early to avoid allocating and inserting a zone write plug for partially written sequential zones if the device natively supports zone append.

2025-03-07arm64/mm: Fix Boot panic on Ampere AltraRyan Roberts
commit 2b1283e1ea9b5e0b06f075f79391a51d9f70749b upstream. When the range of present physical memory is sufficiently small enough and the reserved address space for the linear map is sufficiently large enough, The linear map base address is randomized in arm64_memblock_init(). Prior to commit 62cffa496aac ("arm64/mm: Override PARange for !LPA2 and use it consistently"), we decided if the sizes were suitable with the help of the raw mmfr0.parange. But the commit changed this to use the sanitized version instead. But the function runs before the register has been sanitized so this returns 0, interpreted as a parange of 32 bits. Some fun wrapping occurs and the logic concludes that there is enough room to randomize the linear map base address, when really there isn't. So the top of the linear map ends up outside the reserved address space. Since the PA range cannot be overridden in the first place, restore the mmfr0 reading logic to its state prior to 62cffa496aac, where the raw register value is used.

2025-03-07drm/amd/display: Fix HPD after gpu resetRoman Li
commit 4de141b8b1b7991b607f77e5f4580e1c67c24717 upstream. [Why] DC is not using amdgpu_irq_get/put to manage the HPD interrupt refcounts. So when amdgpu_irq_gpu_reset_resume_helper() reprograms all of the IRQs, HPD gets disabled.
