2024-09-12PCI: Fix potential deadlock in pcim_intx()Philipp Stanner1-0/+2
25216afc9db5 ("PCI: Add managed pcim_intx()") moved the allocation step for pci_intx()'s device resource from pcim_enable_device() to pcim_intx(). As before, pcim_enable_device() sets pci_dev.is_managed to true; and it is never set to false again. Due to the lifecycle of a struct pci_dev, it can happen that a second driver obtains the same pci_dev after a first driver ran. If one driver uses pcim_enable_device() and the other doesn't, this causes the other driver to run into managed pcim_intx(), which will try to allocate when called for the first time. Allocations might sleep, so calling pci_intx() while holding spinlocks becomes then invalid, which causes lockdep warnings and could cause deadlocks: ======================================================== WARNING: possible irq lock inversion dependency detected 6.11.0-rc6+ #59 Tainted: G W -------------------------------------------------------- CPU 0/KVM/1537 just changed the state of lock: ffffa0f0cff965f0 (&vdev->irqlock){-...}-{2:2}, at: vfio_intx_handler+0x21/0xd0 [vfio_pci_core] but this lock took another, HARDIRQ-unsafe lock in the past: (fs_reclaim){+.+.}-{0:0} and interrupts could create inverse lock ordering between them. other info that might help us debug this: Possible interrupt unsafe locking scenario: CPU0 CPU1 ---- ---- lock(fs_reclaim); local_irq_disable(); lock(&vdev->irqlock); lock(fs_reclaim); <Interrupt> lock(&vdev->irqlock); *** DEADLOCK *** Have pcim_enable_device()'s release function, pcim_disable_device(), set pci_dev.is_managed to false so that subsequent drivers using the same struct pci_dev do not implicitly run into managed code.

Move the code "worker->pool = NULL;" out from detach_worker() to fix the problem. worker->pool had been designed to be constant for regular workers and changeable for rescuer. To share attaching/detaching code for regular and rescuer workers and to avoid worker->pool being accessed inadvertently when the worker has been detached, worker->pool is reset to NULL when detached no matter the worker is rescuer or not. To maintain worker->pool being reset after detached, move the code "worker->pool = NULL;" in the worker thread context after detached. It is either be in the regular worker thread context after PF_WQ_WORKER is cleared or in rescuer worker thread context with wq_pool_attach_mutex held. So it is safe to do so.

2024-09-11net: tighten bad gso csum offset check in virtio_net_hdrWillem de Bruijn1-1/+2
The referenced commit drops bad input, but has false positives. Tighten the check to avoid these. The check detects illegal checksum offload requests, which produce csum_start/csum_off beyond end of packet after segmentation. But it is based on two incorrect assumptions: 1. virtio_net_hdr_to_skb with VIRTIO_NET_HDR_GSO_TCP[46] implies GSO. True in callers that inject into the tx path, such as tap. But false in callers that inject into rx, like virtio-net. Here, the flags indicate GRO, and CHECKSUM_UNNECESSARY or CHECKSUM_NONE without VIRTIO_NET_HDR_F_NEEDS_CSUM is normal. 2. TSO requires checksum offload, i.e., ip_summed == CHECKSUM_PARTIAL. False, as tcp[46]_gso_segment will fix up csum_start and offset for all other ip_summed by calling __tcp_v4_send_check. Because of 2, we can limit the scope of the fix to virtio_net_hdr that do try to set these fields, with a bogus value.

Keeping a reference to add_timer inside the lock, and calling sk_stop_timer_sync() with this reference, instead of "entry->add_timer". Move list_del(&entry->list) to mptcp_pm_del_add_timer and inside the pm lock, do not directly access any members of the entry outside the pm lock, which can avoid similar "entry->x" uaf.

2024-09-11net: dsa: felix: ignore pending status of TAS module when it's disabledXiaoliang Yang1-4/+7
The TAS module could not be configured when it's running in pending status. We need disable the module and configure it again. However, the pending status is not cleared after the module disabled. TC taprio set will always return busy even it's disabled. For example, a user uses tc-taprio to configure Qbv and a future basetime. The TAS module will run in a pending status. There is no way to reconfigure Qbv, it always returns busy. Actually the TAS module can be reconfigured when it's disabled. So it doesn't need to check the pending status if the TAS module is disabled. After the patch, user can delete the tc taprio configuration to disable Qbv and reconfigure it again.

2024-09-11selftests: mptcp: join: restrict fullmesh endp on 1st sfMatthieu Baerts (NGI0)1-1/+3
A new endpoint using the IP of the initial subflow has been recently added to increase the code coverage. But it breaks the test when using old kernels not having commit 86e39e04482b ("mptcp: keep track of local endpoint still available for each msk"), e.g. on v5.15. Similar to commit d4c81bbb8600 ("selftests: mptcp: join: support local endpoint being tracked or not"), it is possible to add the new endpoint conditionally, by checking if "mptcp_pm_subflow_check_next" is present in kallsyms: this is not directly linked to the commit introducing this symbol but for the parent one which is linked anyway. So we can know in advance what will be the expected behaviour, and add the new endpoint only when it makes sense to do so.

2024-09-12netfilter: nft_socket: make cgroupsv2 matching work with namespacesFlorian Westphal1-3/+38
When running in container environmment, /sys/fs/cgroup/ might not be the real root node of the sk-attached cgroup. Example: In container: % stat /sys//fs/cgroup/ Device: 0,21 Inode: 2214 .. % stat /sys/fs/cgroup/foo Device: 0,21 Inode: 2264 .. The expectation would be for: nft add rule .. socket cgroupv2 level 1 "foo" counter to match traffic from a process that got added to "foo" via "echo $pid > /sys/fs/cgroup/foo/cgroup.procs". However, 'level 3' is needed to make this work. Seen from initial namespace, the complete hierarchy is: % stat /sys/fs/cgroup/system.slice/docker-.../foo Device: 0,21 Inode: 2264 .. i.e. hierarchy is 0 1 2 3 / -> system.slice -> docker-1... -> foo ... but the container doesn't know that its "/" is the "docker-1.." cgroup. Current code will retrieve the 'system.slice' cgroup node and store its kn->id in the destination register, so compare with 2264 ("foo" cgroup id) will not match. Fetch "/" cgroup from ->init() and add its level to the level we try to extract. cgroup root-level is 0 for the init-namespace or the level of the ancestor that is exposed as the cgroup root inside the container. In the above case, cgrp->level of "/" resolved in the container is 2 (docker-1...scope/) and request for 'level 1' will get adjusted to fetch the actual level (3). v2: use CONFIG_SOCK_CGROUP_DATA, eval function depends on it.

2024-09-11minmax: reduce min/max macro expansion in atomisp driverLorenzo Stoakes1-7/+19
Avoid unnecessary nested min()/max() which results in egregious macro expansion. Use clamp_t() as this introduces the least possible expansion, and turn the {s,u}DIGIT_FITTING() macros into inline functions to avoid the nested expansion. This resolves an issue with slackware 15.0 32-bit compilation as reported by Richard Narron. Presumably the min/max fixups would be difficult to backport, this patch should be easier and fix's Richard's problem in 5.15.

2024-09-11drm/amd/display: Add all planes on CRTC to state for overlay cursorLeo Li1-0/+11
[Why] DC has a special commit path for native cursor, which use the built-in cursor pipe within DCN planes. This update path does not require all enabled planes to be added to the list of surface updates sent to DC. This is not the case for overlay cursor; it uses the same path as MPO commits. This update path requires all enabled planes to be added to the list of surface updates sent to DC. Otherwise, DC will disable planes not inside the list. [How] If overlay cursor is needed, add all planes on the same CRTC as this cursor to the atomic state. This is already done for non-cursor planes (MPO), just before the added lines.

2024-09-10riscv: Disable preemption while handling PR_RISCV_CTX_SW_FENCEI_OFFCharlie Jenkins1-6/+6
The icache will be flushed in switch_to() if force_icache_flush is true, or in flush_icache_deferred() if icache_stale_mask is set. Between setting force_icache_flush to false and calculating the new icache_stale_mask, preemption needs to be disabled. There are two reasons for this: 1. If CPU migration happens between force_icache_flush = false, and the icache_stale_mask is set, an icache flush will not be emitted. 2. smp_processor_id() is used in set_icache_stale_mask() to mark the current CPU as not needing another flush since a flush will have happened either by userspace or by the kernel when performing the migration. smp_processor_id() is currently called twice with preemption enabled which causes a race condition. It allows icache_stale_mask to be populated with inconsistent CPU ids. Resolve these two issues by setting the icache_stale_mask before setting force_icache_flush to false, and using get_cpu()/put_cpu() to obtain the smp_processor_id().

2024-09-10drm/amd/display: Do not reset planes based on crtc zpos_changedLeo Li1-1/+1
[Why] drm_normalize_zpos will set the crtc_state->zpos_changed to 1 if any of it's assigned planes changes zpos, or is removed/added from it. To have amdgpu_dm request a plane reset on this is too broad. For example, if only the cursor plane was moved from one crtc to another, the crtc's zpos_changed will be set to true. But that does not mean that the underlying primary plane requires a reset. [How] Narrow it down so that only the plane that has a change in zpos will require a reset. As a future TODO, we can further optimize this by only requiring a reset on z-order change. Z-order is different from z-pos, since a zpos change doesn't necessarily mean the z-ordering changed, and DC should only require a reset if the z-ordering changed. For example, the following zpos update does not change z-ordering: Plane A: zpos 2 -> 3 Plane B: zpos 1 -> 2 => Plane A is still on top of plane B: no reset needed Whereas this one does change z-ordering: Plane A: zpos 2 -> 1 Plane B: zpos 1 -> 2 => Plane A changed from on top, to below plane B: reset needed Fixes: 38e0c3df6dbd ("drm/amd/display: Move PRIMARY plane zpos higher") Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/3569 Signed-off-by: Leo Li <[email protected]> Reviewed-by: Harry Wentland <[email protected]> Signed-off-by: Alex Deucher <[email protected]> (cherry picked from commit 578aab4ecc73476393389440724b7a391cc0cea9)
2024-09-10drm/amd/display: Avoid race between dcn35_set_drr() and dc_state_destruct()Tobias Jakobi1-8/+12
dc_state_destruct() nulls the resource context of the DC state. The pipe context passed to dcn35_set_drr() is a member of this resource context. If dc_state_destruct() is called parallel to the IRQ processing (which calls dcn35_set_drr() at some point), we can end up using already nulled function callback fields of struct stream_resource. The logic in dcn35_set_drr() already tries to avoid this, by checking tg against NULL. But if the nulling happens exactly after the NULL check and before the next access, then we get a race. Avoid this by copying tg first to a local variable, and then use this variable for all the operations. This should work, as long as nobody frees the resource pool where the timing generators live.

2024-09-10block: Prevent deadlocks when switching elevatorsDamien Le Moal3-7/+38
Commit af2814149883 ("block: freeze the queue in queue_attr_store") changed queue_attr_store() to always freeze a sysfs attribute queue before calling the attribute store() method, to ensure that no IOs are in-flight when an attribute value is being updated. However, this change created a potential deadlock situation for the scheduler queue attribute as changing the queue elevator with elv_iosched_store() can result in a call to request_module() if the user requested module is not already registered. If the file of the requested module is stored on the block device of the frozen queue, a deadlock will happen as the read operations triggered by request_module() will wait for the queue freeze to end. Solve this issue by introducing the load_module method in struct queue_sysfs_entry, and to calling this method function in queue_attr_store() before freezing the attribute queue. The macro definition QUEUE_RW_LOAD_MODULE_ENTRY() is added to define a queue sysfs attribute that needs loading a module. The definition of the scheduler atrribute is changed to using QUEUE_RW_LOAD_MODULE_ENTRY(), with the function elv_iosched_load_module() defined as the load_module method. elv_iosched_store() can then be simplified to remove the call to request_module().

Commit <17de3f5fdd35> ("iommu: Retire bus ops") removes iommu ops from the bus structure. The iommu subsystem no longer relies on bus for operations. So iommu_domain_alloc() interface is no longer relevant. Replace iommu_domain_alloc() with iommu_paging_domain_alloc() which takes the physical device from which the host1x_device virtual device was instantiated. This physical device is a common parent to all physical devices that are part of the virtual device.
