2024-10-08x86/entry_32: Clear CPU buffers after register restore in NMI returnPawan Gupta
CPU buffers are currently cleared after call to exc_nmi, but before register state is restored. This may be okay for MDS mitigation but not for RDFS. Because RDFS mitigation requires CPU buffers to be cleared when registers don't have any sensitive data. Move CLEAR_CPU_BUFFERS after RESTORE_ALL_NMI.

2024-10-08igb: Do not bring the device up after non-fatal errorMohamed Khalfella
Commit 004d25060c78 ("igb: Fix igb_down hung on surprise removal") changed igb_io_error_detected() to ignore non-fatal pcie errors in order to avoid hung task that can happen when igb_down() is called multiple times. This caused an issue when processing transient non-fatal errors. igb_io_resume(), which is called after igb_io_error_detected(), assumes that device is brought down by igb_io_error_detected() if the interface is up.

2024-10-08i40e: Fix macvlan leak by synchronizing access to mac_filter_hashAleksandr Loktionov
This patch addresses a macvlan leak issue in the i40e driver caused by concurrent access to vsi->mac_filter_hash. The leak occurs when multiple threads attempt to modify the mac_filter_hash simultaneously, leading to inconsistent state and potential memory leaks. To fix this, we now wrap the calls to i40e_del_mac_filter() and zeroing vf->default_lan_addr.addr with spin_lock/unlock_bh(&vsi->mac_filter_hash_lock), ensuring atomic operations and preventing concurrent access. Additionally, we add lockdep_assert_held(&vsi->mac_filter_hash_lock) in i40e_add_mac_filter() to help catch similar issues in the future. Reproduction steps: 1. Spawn VFs and configure port vlan on them. 2. Trigger concurrent macvlan operations (e.g., adding and deleting portvlan and/or mac filters). 3. Observe the potential memory leak and inconsistent state in the mac_filter_hash. This synchronization ensures the integrity of the mac_filter_hash and prevents the described leak.

2024-10-08ice: Fix increasing MSI-X on VFMarcin Szycik
Increasing MSI-X value on a VF leads to invalid memory operations. This is caused by not reallocating some arrays.

2024-10-08ice: Flush FDB entries before resetWojciech Drewek
Triggering the reset while in switchdev mode causes errors[1]. Rules are already removed by this time because switch content is flushed in case of the reset. This means that rules were deleted from HW but SW still thinks they exist so when we get SWITCHDEV_FDB_DEL_TO_DEVICE notification we try to delete not existing rule. We can avoid these errors by clearing the rules early in the reset flow before they are removed from HW. Switchdev API will get notified that the rule was removed so we won't get SWITCHDEV_FDB_DEL_TO_DEVICE notification. Remove unnecessary ice_clear_sw_switch_recipes.

Convert all platform drivers below drivers/video/fbdev to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

2024-10-08powercap: intel_rapl_tpmi: Ignore minor version changeZhang Rui
The hardware definition of every TPMI feature contains a major and minor version. When there is a change in the MMIO offset or change in the definition of a field, hardware will change major version. For addition of new fields without modifying existing MMIO offsets or fields, only the minor version is changed. If the driver has not been updated to recognize a new hardware major version, it cannot provide the RAPL interface to users due to possible register layout incompatibilities. However, the driver does not need to be updated every time the hardware minor version changes because in that case it will just miss some new functionality exposed by the hardware. The current implementation causes the driver to refuse to work for any hardware version change which is unnecessarily restrictive. If there is a minor version mismatch, log an information message and continue, but if there is a major version mismatch, log a warning and exit (as before).

2024-10-08x86/resctrl: Annotate get_mem_config() functions as __initNathan Chancellor
After a recent LLVM change [1] that deduces __cold on functions that only call cold code (such as __init functions), there is a section mismatch warning from __get_mem_config_intel(), which got moved to .text.unlikely. as a result of that optimization: WARNING: modpost: vmlinux: section mismatch in reference: \ __get_mem_config_intel+0x77 (section: .text.unlikely.) -> thread_throttle_mode_init (section: .init.text) Mark __get_mem_config_intel() as __init as well since it is only called from __init code, which clears up the warning. While __rdt_get_mem_config_amd() does not exhibit a warning because it does not call any __init code, it is a similar function that is only called from __init code like __get_mem_config_intel(), so mark it __init as well to keep the code symmetrical.

A large number of cpuset cgroups are deleted. 2. Set cpu on and off repeatly. 3. Set watchdog_thresh repeatly. The scripts can be obtained at LINK mentioned above the signature. The reason for this issue is cgroup_mutex and cpu_hotplug_lock are acquired in different tasks, which may lead to deadlock. It can lead to a deadlock through the following steps: 1. A large number of cpusets are deleted asynchronously, which puts a large number of cgroup_bpf_release works into system_wq. The max_active of system_wq is WQ_DFL_ACTIVE(256). Consequently, all active works are cgroup_bpf_release works, and many cgroup_bpf_release works will be put into inactive queue. As illustrated in the diagram, there are 256 (in the acvtive queue) + n (in the inactive queue) works. 2. Setting watchdog_thresh will hold cpu_hotplug_lock.read and put smp_call_on_cpu work into system_wq. However step 1 has already filled system_wq, 'sscs.work' is put into inactive queue. 'sscs.work' has to wait until the works that were put into the inacvtive queue earlier have executed (n cgroup_bpf_release), so it will be blocked for a while. 3. Cpu offline requires cpu_hotplug_lock.write, which is blocked by step 2. 4. Cpusets that were deleted at step 1 put cgroup_release works into cgroup_destroy_wq. They are competing to get cgroup_mutex all the time. When cgroup_metux is acqured by work at css_killed_work_fn, it will call cpuset_css_offline, which needs to acqure cpu_hotplug_lock.read. However, cpuset_css_offline will be blocked for step 3. 5. At this moment, there are 256 works in active queue that are cgroup_bpf_release, they are attempting to acquire cgroup_mutex, and as a result, all of them are blocked. Consequently, sscs.work can not be executed. Ultimately, this situation leads to four processes being blocked, forming a deadlock. system_wq(step1) WatchDog(step2) cpu offline(step3) cgroup_destroy_wq(step4) ... 2000+ cgroups deleted asyn 256 actives + n inactives __lockup_detector_reconfigure P(cpu_hotplug_lock.read) put sscs.work into system_wq 256 + n + 1(sscs.work) sscs.work wait to be executed warting sscs.work finish percpu_down_write P(cpu_hotplug_lock.write) ...blocking... css_killed_work_fn P(cgroup_mutex) cpuset_css_offline P(cpu_hotplug_lock.read) ...blocking... 256 cgroup_bpf_release mutex_lock(&cgroup_mutex); ..blocking... To fix the problem, place cgroup_bpf_release works on a dedicated workqueue which can break the loop and solve the problem. System wqs are for misc things which shouldn't create a large number of concurrent work items. If something is going to generate >WQ_DFL_ACTIVE(256) concurrent work items, it should use its own dedicated workqueue.

2024-10-08iommu/arm-smmu-v3: Fix last_sid_idx calculation for sid_bits==32Daniel Mentz
The function arm_smmu_init_strtab_2lvl uses the expression ((1 << smmu->sid_bits) - 1) to calculate the largest StreamID value. However, this fails for the maximum allowed value of SMMU_IDR1.SIDSIZE which is 32. The C standard states: "If the value of the right operand is negative or is greater than or equal to the width of the promoted left operand, the behavior is undefined." With smmu->sid_bits being 32, the prerequisites for undefined behavior are met. We observed that the value of (1 << 32) is 1 and not 0 as we initially expected. Similar bit shift operations in arm_smmu_init_strtab_linear seem to not be affected, because it appears to be unlikely for an SMMU to have SMMU_IDR1.SIDSIZE set to 32 but then not support 2-level Stream tables This issue was found by Ryan Huang <tzukui@google.com> on our team.

2024-10-08irqchip/sifive-plic: Unmask interrupt in plic_irq_enable()Nam Cao
It is possible that an interrupt is disabled and masked at the same time. When the interrupt is enabled again by enable_irq(), only plic_irq_enable() is called, not plic_irq_unmask(). The interrupt remains masked and never raises. An example where interrupt is both disabled and masked is when handle_fasteoi_irq() is the handler, and IRQS_ONESHOT is set. The interrupt handler: 1. Mask the interrupt 2. Handle the interrupt 3. Check if interrupt is still enabled, and unmask it (see cond_unmask_eoi_irq()) If another task disables the interrupt in the middle of the above steps, the interrupt will not get unmasked, and will remain masked when it is enabled in the future. The problem is occasionally observed when PREEMPT_RT is enabled, because PREEMPT_RT adds the IRQS_ONESHOT flag. But PREEMPT_RT only makes the problem more likely to appear, the bug has been around since commit a1706a1c5062 ("irqchip/sifive-plic: Separate the enable and mask operations").

Plug the race by checking the value of vmapp_count, which tracks whether the VPE is mapped ot not, and returning an error in this case.

2024-10-08x86/resctrl: Avoid overflow in MB settings in bw_validate()Martin Kletzander
The resctrl schemata file supports specifying memory bandwidth associated with the Memory Bandwidth Allocation (MBA) feature via a percentage (this is the default) or bandwidth in MiBps (when resctrl is mounted with the "mba_MBps" option). The allowed range for the bandwidth percentage is from /sys/fs/resctrl/info/MB/min_bandwidth to 100, using a granularity of /sys/fs/resctrl/info/MB/bandwidth_gran. The supported range for the MiBps bandwidth is 0 to U32_MAX. There are two issues with parsing of MiBps memory bandwidth: * The user provided MiBps is mistakenly rounded up to the granularity that is unique to percentage input. * The user provided MiBps is parsed using unsigned long (thus accepting values up to ULONG_MAX), and then assigned to u32 that could result in overflow. Do not round up the MiBps value and parse user provided bandwidth as the u32 it is intended to be. Use the appropriate kstrtou32() that can detect out of range values.

Performing a dummy read ensures that the register write operation is fully completed, mitigating any potential bus delays that could otherwise impact the frequency of bitbang usage. E.g., if the JTAG application uses GPIO to control the JTAG pins (TCK, TMS, TDI, TDO, and TRST), and the application sets the TCK clock to 1 MHz, the GPIO's high/low transitions will rely on a delay function to ensure the clock frequency does not exceed 1 MHz. However, this can lead to rapid toggling of the GPIO because the write operation is POSTed and does not wait for a bus acknowledgment.

2024-10-08nouveau/dmem: Fix vulnerability in migrate_to_ram upon copy errorYonatan Maman
The `nouveau_dmem_copy_one` function ensures that the copy push command is sent to the device firmware but does not track whether it was executed successfully. In the case of a copy error (e.g., firmware or hardware failure), the copy push command will be sent via the firmware channel, and `nouveau_dmem_copy_one` will likely report success, leading to the `migrate_to_ram` function returning a dirty HIGH_USER page to the user. This can result in a security vulnerability, as a HIGH_USER page that may contain sensitive or corrupted data could be returned to the user. To prevent this vulnerability, we allocate a zero page. Thus, in case of an error, a non-dirty (zero) page will be returned to the user.

Commit 9ee3f0d8c999 ("ASOC: SOF: Intel: hda-loader: only wait for HDaudio IOC for IPC4 devices") removed DMA wait for IPC3 case. Proceed and remove the wait for IPC4 devices as well. There is no dependency to IPC version in the load logic and checking the firmware status is a sufficient check in case of errors. The removed code also had a bug in that -ETIMEDOUT is returned without stopping the DMA transfer.
