While this is today done by the GuC firmware, according to the design, this should be responsibility of the PF driver, as future platforms may require more registers to be reset. Likewise GuC, the PF can access VFs registers by adding some platform specific offset to the original register address.

Since the current field isn't being used for anything, change the assignments to 4MB (the size of the register region on all current platform) and rename the field to 'regs_size' to more clearly describe what it represents.

Fix that by dropping the ref using xe_bo_put_deferred(), and moving the final commit outside of the lock. Dropping the lock around the put is tricky since the bo can go out of scope and delete itself from the list, making it difficult to navigate to the next list entry.

This isn't true for all adapters with this branch device though (for instance the Cakitte USBC->2xHDMI adapter reported in the Closes link below doesn't support DSC).

Given that non-root tiles get initialized later than the root tile (and currently after the point at which GT MMIO is initialized for _all_ GTs), we wind up incorrectly inheriting uninitialized pointers for the initialization of GT MMIO for GTs that reside on non-root tiles. This causes a driver crash on multi-tile PVC platforms. With the general xe_mmio redesign, it's now only necessary to do the GT-level MMIO setup before the point we start reading/writing GT registers. Move initialization of gt->mmio out of xe_info_init (which runs before non-root tiles are initialized) and to the beginning of where we start actually accessing the GTs themselves. The high-level initialization flow now boils down to: - General device init, software-only setup - (no register access possible yet) - Root tile initialization - (access to device/tile0 registers possible via xe_root_tile_mmio()) - Initialization of non-root tiles - (access to any tile's registers possible via tile->mmio) - GT MMIO initialization, inheriting iomap from each GT's tile - (access to any GT's registers possible via gt->mmio) Fixes: fa599b8c95a7 ("drm/xe: Populate GT's mmio iomap from tile during init") Reported-by: John Harrison Signed-off-by: Matt Roper Reviewed-by: Sai Teja Pottumuttu Link: https://patchwork.freedesktop.org/patch/msgid/20240917221615.875962-2-matthew.d.roper@intel.com --- drivers/gpu/drm/xe/xe_device.c | 7 +++++++ drivers/gpu/drm/xe/xe_gt.c | 24 ++++++++++++++++++++++++ drivers/gpu/drm/xe/xe_gt.h | 1 + drivers/gpu/drm/xe/xe_pci.c | 12 ------------ 4 files changed, 32 insertions(+), 12 deletions(-) diff --git a/drivers/gpu/drm/xe/xe_device.c b/drivers/gpu/drm/xe/xe_device.c index 38eade07a004..709acea5c388 100644 --- a/drivers/gpu/drm/xe/xe_device.c +++ b/drivers/gpu/drm/xe/xe_device.c @@ -654,6 +654,13 @@ int xe_device_probe(struct xe_device *xe) err = xe_gt_init_early(gt); if (err) return err; + + /* + * Only after this point can GT-specific MMIO operations + * (including things like communication with the GuC) + * be performed. + */ + xe_gt_mmio_init(gt); } for_each_tile(tile, xe, id) { diff --git a/drivers/gpu/drm/xe/xe_gt.c b/drivers/gpu/drm/xe/xe_gt.c index 935d1dfd9459..274737417b0f 100644 --- a/drivers/gpu/drm/xe/xe_gt.c +++ b/drivers/gpu/drm/xe/xe_gt.c @@ -625,6 +625,30 @@ int xe_gt_init(struct xe_gt *gt) return 0; } +/** + * xe_gt_mmio_init() - Initialize GT's MMIO access + * @gt: the GT object + * + * Initialize GT's MMIO accessor, which will be used to access registers inside + * this GT. + */ +void xe_gt_mmio_init(struct xe_gt *gt) +{ + struct xe_tile *tile = gt_to_tile(gt); + + gt->mmio.regs = tile->mmio.regs; + gt->mmio.regs_size = tile->mmio.regs_size; + gt->mmio.tile = tile; + + if (gt->info.type == XE_GT_TYPE_MEDIA) { + gt->mmio.adj_offset = MEDIA_GT_GSI_OFFSET; + gt->mmio.adj_limit = MEDIA_GT_GSI_LENGTH; + } + + if (IS_SRIOV_VF(gt_to_xe(gt))) + gt->mmio.sriov_vf_gt = gt; +} + void xe_gt_record_user_engines(struct xe_gt *gt) { struct xe_hw_engine *hwe; diff --git a/drivers/gpu/drm/xe/xe_gt.h b/drivers/gpu/drm/xe/xe_gt.h index 97def44afa4c..05c8351d0f39 100644 --- a/drivers/gpu/drm/xe/xe_gt.h +++ b/drivers/gpu/drm/xe/xe_gt.h @@ -37,6 +37,7 @@ struct xe_gt *xe_gt_alloc(struct xe_tile *tile); int xe_gt_init_hwconfig(struct xe_gt *gt); int xe_gt_init_early(struct xe_gt *gt); int xe_gt_init(struct xe_gt *gt); +void xe_gt_mmio_init(struct xe_gt *gt); void xe_gt_declare_wedged(struct xe_gt *gt); int xe_gt_record_default_lrcs(struct xe_gt *gt); diff --git a/drivers/gpu/drm/xe/xe_pci.c b/drivers/gpu/drm/xe/xe_pci.c index 2c2d269ebe8e..edaeefd2d648 100644 --- a/drivers/gpu/drm/xe/xe_pci.c +++ b/drivers/gpu/drm/xe/xe_pci.c @@ -716,11 +716,6 @@ static int xe_info_init(struct xe_device *xe, gt->info.type = XE_GT_TYPE_MAIN; gt->info.has_indirect_ring_state = graphics_desc->has_indirect_ring_state; gt->info.engine_mask = graphics_desc->hw_engine_mask; - gt->mmio.regs = tile->mmio.regs; - gt->mmio.regs_size = tile->mmio.regs_size; - gt->mmio.tile = tile; - if (IS_SRIOV_VF(xe)) - gt->mmio.sriov_vf_gt = gt; if (MEDIA_VER(xe) < 13 && media_desc) gt->info.engine_mask |= media_desc->hw_engine_mask; @@ -740,13 +735,6 @@ static int xe_info_init(struct xe_device *xe, gt->info.type = XE_GT_TYPE_MEDIA; gt->info.has_indirect_ring_state = media_desc->has_indirect_ring_state; gt->info.engine_mask = media_desc->hw_engine_mask; - gt->mmio.regs = tile->mmio.regs; - gt->mmio.regs_size = tile->mmio.regs_size; - gt->mmio.adj_offset = MEDIA_GT_GSI_OFFSET; - gt->mmio.adj_limit = MEDIA_GT_GSI_LENGTH; - gt->mmio.tile = tile; - if (IS_SRIOV_VF(xe)) - gt->mmio.sriov_vf_gt = gt; /* * FIXME: At the moment multi-tile and standalone media are From b46afdac45a251d76a4575be78beba343f08b52f Mon Sep 17 00:00:00 2001 From: Ilia Levi Date: Wed, 18 Sep 2024 08:39:38 +0300 Subject: [PATCH 098/474] drm/xe: Introduce dedicated config for memirq debug Separate config for debugging memory based interrupts (memirq) infrastructure.

For this scenario, in order to differentiate between the engines, we need to pass different status/source pointers in the LRC. The requirements on those pointers are: - Interrupt status should be 4KiB aligned - Interrupt source should be 64 bytes aligned To accommodate this, we duplicate the current memirq page layout - allocating a page for each engine instance and pass this page in the LRC. Note that the same page can be reused for different engine types. For example, an LRC executing on CCS #x will have pointers to page #x, and an LRC executing on BCS #x will have the same pointers. Thus, to locate the proper page, the pointer accessors were modified to receive the hw engine.

Let's also implement them for the media GT when applicable. According to our spec, media GT registers CCCHKNREG1 and L3SQCREG* exist only in Xe2_LPM and their offsets do not match their primary GT counterparts. Furthermore, the range where CCCHKNREG1 belongs is not listed as a multicast range on the media GT. As such, we need to have Xe2_LPM-specific definitions for those registers and apply the setting only for that specific IP. Both Xe2_HPM and Xe2_LPM contain STATELESS_COMPRESSION_CTRL and the offset on the media GT matches the one on the primary one. So we can simply have a copy of "Tuning: Stateless compression control" for the media GT. v2: - Fix implementation with respect to multicast vs non-multicast registers. (Matt) - Add missing XE2LPM_CCCHKNREG1 on second action of "Tuning: Compression Overfetch - media". v3: - STATELESS_COMPRESSION_CTRL on Xe2_HPM is also a multicast register, do not define a XE2HPM_STATELESS_COMPRESSION_CTRL register.

According to RCU usage rules, this is illegal and can lead to unpredictable behavior, such as accessing memory that has been updated or causing use-after-free issues. This possible bug was identified using a static analysis tool developed by myself, specifically designed to detect RCU-related issues. To address this, the `scan_req->type` value is now stored in a local variable `scan_req_type` while still within the RCU read-side critical section. The `scan_req_type` is then used after the RCU lock is released, ensuring that the type value is safely accessed without violating RCU rules.

This could fail, e.g. under memory pressure, when the IOMMU driver just can't allocate more memory for page tables. While the code tries to handle this in the path below the err_unmap label it erroneously unmaps one entry from the sq's FIFO list of active mappings. Since the current map attempt failed this unmap is removing some random DMA mapping that might still be required. If the PCI function now presents that IOVA, the IOMMU may assumes a rogue DMA access and e.g. on s390 puts the PCI function in error state. The erroneous behavior was seen in a stress-test environment that created memory pressure.

It was seen in the field that crdump can take more than 5 seconds to complete. During that time mlx5_vsc_wait_on_flag() did not release the cpu because it did not complete 16 iterations. It is believed that pci config reads were slow. Adding cond_resched() every 128 register read improves the situation. In the common case the, crdump takes ~1.8989s, the thread yields the cpu every ~4.51ms. If crdump takes ~5s, the thread yields the cpu every ~18.0ms.

Thus, require that `T: Sync` when calling the `access` method. An alternative is to require `T: Sync` in the `impl Sync for LockedBy`. This patch does not choose that approach as it gives up the ability to use `LockedBy` with `!Sync` types, which is okay as long as you only use `access_mut`.

The helpers are then have `RUST_CONST_HELPER` prefix stripped and exposed to Rust code as if `ARCH_SLAB_MISALIGN` is generated natively by bindgen. This works well for most constants, but on RISC-V, `ARCH_SLAB_MINALIGN` is defined directly as literal constant if `!CONFIG_MMU`, and bindgen would generate `ARCH_SLAB_MINALIGN` directly, thus conflict with the one generated through the helper. To fix this, we simply need to block bindgen from generating directly without going through helper.

From 4c66f8307ac099f89038878b7789d72163a74751 Mon Sep 17 00:00:00 2001 From: Alice Ryhl Date: Wed, 25 Sep 2024 08:10:18 +0000 Subject: [PATCH 153/474] cfi: encode cfi normalized integers + kasan/gcov bug in Kconfig There is a bug in the LLVM implementation of KASAN and GCOV that makes these options incompatible with the CFI_ICALL_NORMALIZE_INTEGERS option. The bug has already been fixed in llvm/clang [1] and rustc [2]. However, Kconfig currently has no way to gate features on the LLVM version inside rustc, so we cannot write down a precise `depends on` clause in this case. Instead, a `def_bool` option is defined for whether CFI_ICALL_NORMALIZE_INTEGERS is available, and its default value is set to false when GCOV or KASAN are turned on. End users using a patched clang/rustc can turn on the HAVE_CFI_ICALL_NORMALIZE_INTEGERS option directly to override this. An alternative solution is to inspect a binary created by clang or rustc to see whether the faulty CFI tags are in the binary. This would be a precise check, but it would involve hard-coding the *hashed* version of the CFI tag. This is because there's no way to get clang or rustc to output the unhased version of the CFI tag. Relying on the precise hashing algorithm using by CFI seems too fragile, so I have not pursued this option. Besides, this kind of hack is exactly what lead to the LLVM bug in the first place. If the CFI_ICALL_NORMALIZE_INTEGERS option is used without CONFIG_RUST, then we actually can perform a precise check today: just compare the clang version number. This works since clang and llvm are always updated in lockstep. However, encoding this in Kconfig would give the HAVE_CFI_ICALL_NORMALIZE_INTEGERS option a dependency on CONFIG_RUST, which is not possible as the reverse dependency already exists. HAVE_CFI_ICALL_NORMALIZE_INTEGERS is defined to be a `def_bool` instead of `bool` to avoid asking end users whether they want to turn on the option. Turning it on explicitly is something only experts should do, so making it hard to do so is not an issue. I added a `depends on CFI_CLANG` clause to the new Kconfig option. I'm not sure whether that makes sense or not, but it doesn't seem to make a big difference. In a future kernel release, I would like to add a Kconfig option similar to CLANG_VERSION/RUSTC_VERSION for inspecting the version of the LLVM inside rustc. Once that feature lands, this logic will be replaced with a precise version check. This check is not being introduced here to avoid introducing a new _VERSION constant in a fix.

All tasks are queued into the global DSQ and all CPUs try to execute tasks from it. This creates a lot of cross-node cacheline accesses and scheduling across the node boundaries, and can lead to live-lock conditions where the system takes tens of minutes to disable the BPF scheduler while executing in the bypass mode. Split the global DSQ per NUMA node. Each node has its own global DSQ. When a task is dispatched to SCX_DSQ_GLOBAL, it's put into the global DSQ local to the task's CPU and all CPUs in a node only consume its node-local global DSQ. This resolves a livelock condition which could be reliably triggered on an 2x EPYC 7642 system by running `stress-ng --race-sched 1024` together with `stress-ng --workload 80 --workload-threads 10` while repeatedly enabling and disabling a SCX scheduler.

As such, the best place to call it is in the same cpu_read_lock() section that enables the CPU hotplug ops. Currently, it is called in the next cpus_read_lock() block in scx_ops_enable(). The side effect of this placement is a small window in which hotplug sequence detection can trigger unnecessarily, which isn't critical. Move check_hotplug_seq() invocation to the same cpus_read_lock() block as the hotplug operation enablement to close the window and get the invocation out of the way for planned locking updates.

However, in the gap between setting __scx_ops_enabled and preeempt_disable(), an external entity can put tasks including the enabling one into SCX prematurely, which can lead to malfunctions including stalls. The bypass mode can wrap the entire enabling operation and guarantee forward progress no matter what the BPF scheduler does. Use the bypass mode instead to guarantee forward progress while enabling. While at it, release and regrab scx_tasks_lock between the two task iteration locks in scx_ops_enable() for clarity as there is no reason to keep holding the lock between them.

This is because SCX_HAS_OP(cgroupt_init) is used to test both whether SCX cgroup operations are enabled and ops.cgroup_init() exists.

Make all cgroup operations consistently use scx_cgroup_enabled to test whether cgroup operations are enabled. scx_cgroup_enabled is added instead of using scx_enabled() to ease planned locking updates.

Currently, the locks are grabbed together which is prone to locking order problems. For example, currently, there is a possible deadlock involving scx_fork_rwsem and cpus_read_lock. cpus_read_lock has to nest inside scx_fork_rwsem due to locking order existing in other subsystems. However, there exists a dependency in the other direction during hotplug if hotplug needs to fork a new task, which happens in some cases. This leads to the following deadlock: scx_ops_enable() hotplug percpu_down_write(&cpu_hotplug_lock) percpu_down_write(&scx_fork_rwsem) block on cpu_hotplug_lock kthread_create() waits for kthreadd kthreadd blocks on scx_fork_rwsem Note that this doesn't trigger lockdep because the hotplug side dependency bounces through kthreadd. With the preceding scx_cgroup_enabled change, this can be solved by decoupling cpus_read_lock, which is needed for static_key manipulations, from the other two locks. - Move the first block of static_key manipulations outside of scx_fork_rwsem and scx_cgroup_rwsem. This is now safe with the preceding scx_cgroup_enabled change. - Drop scx_cgroup_rwsem and scx_fork_rwsem between the two task iteration blocks so that __scx_ops_enabled static_key enabling is outside the two rwsems.

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.

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.

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.

This solves the issue of disable_irq() not working as expected on such platforms. Fixes: 23265442b02b ("ARM: davinci: irq_data conversion.")

Contents: + + * Overview + * Initialisation + * Adding and removing folios + * Querying information about a folio + * Querying information about a folio_queue + * Folio queue iteration + * Folio marks + * Lockless simultaneous production/consumption issues + + +Overview +======== + +The folio_queue struct forms a single segment in a segmented list of folios +that can be used to form an I/O buffer. As such, the list can be iterated over +using the ITER_FOLIOQ iov_iter type. + +The publicly accessible members of the structure are:: + + struct folio_queue { + struct folio_queue *next; + struct folio_queue *prev; + ... + }; + +A pair of pointers are provided, ``next`` and ``prev``, that point to the +segments on either side of the segment being accessed. Whilst this is a +doubly-linked list, it is intentionally not a circular list; the outward +sibling pointers in terminal segments should be NULL. + +Each segment in the list also stores: + + * an ordered sequence of folio pointers, + * the size of each folio and + * three 1-bit marks per folio, + +but hese should not be accessed directly as the underlying data structure may +change, but rather the access functions outlined below should be used. + +The facility can be made accessible by:: + + #include + +and to use the iterator:: + + #include + + +Initialisation +============== + +A segment should be initialised by calling:: + + void folioq_init(struct folio_queue *folioq); + +with a pointer to the segment to be initialised. Note that this will not +necessarily initialise all the folio pointers, so care must be taken to check +the number of folios added. + + +Adding and removing folios +========================== + +Folios can be set in the next unused slot in a segment struct by calling one +of:: + + unsigned int folioq_append(struct folio_queue *folioq, + struct folio *folio); + + unsigned int folioq_append_mark(struct folio_queue *folioq, + struct folio *folio); + +Both functions update the stored folio count, store the folio and note its +size. The second function also sets the first mark for the folio added. Both +functions return the number of the slot used. [!] Note that no attempt is made +to check that the capacity wasn't overrun and the list will not be extended +automatically. + +A folio can be excised by calling:: + + void folioq_clear(struct folio_queue *folioq, unsigned int slot); + +This clears the slot in the array and also clears all the marks for that folio, +but doesn't change the folio count - so future accesses of that slot must check +if the slot is occupied. + + +Querying information about a folio +================================== + +Information about the folio in a particular slot may be queried by the +following function:: + + struct folio *folioq_folio(const struct folio_queue *folioq, + unsigned int slot); + +If a folio has not yet been set in that slot, this may yield an undefined +pointer. The size of the folio in a slot may be queried with either of:: + + unsigned int folioq_folio_order(const struct folio_queue *folioq, + unsigned int slot); + + size_t folioq_folio_size(const struct folio_queue *folioq, + unsigned int slot); + +The first function returns the size as an order and the second as a number of +bytes. + + +Querying information about a folio_queue +======================================== + +Information may be retrieved about a particular segment with the following +functions:: + + unsigned int folioq_nr_slots(const struct folio_queue *folioq); + + unsigned int folioq_count(struct folio_queue *folioq); + + bool folioq_full(struct folio_queue *folioq); + +The first function returns the maximum capacity of a segment. It must not be +assumed that this won't vary between segments. The second returns the number +of folios added to a segments and the third is a shorthand to indicate if the +segment has been filled to capacity. + +Not that the count and fullness are not affected by clearing folios from the +segment. These are more about indicating how many slots in the array have been +initialised, and it assumed that slots won't get reused, but rather the segment +will get discarded as the queue is consumed. + + +Folio marks +=========== + +Folios within a queue can also have marks assigned to them. These marks can be +used to note information such as if a folio needs folio_put() calling upon it. +There are three marks available to be set for each folio. + +The marks can be set by:: + + void folioq_mark(struct folio_queue *folioq, unsigned int slot); + void folioq_mark2(struct folio_queue *folioq, unsigned int slot); + void folioq_mark3(struct folio_queue *folioq, unsigned int slot); + +Cleared by:: + + void folioq_unmark(struct folio_queue *folioq, unsigned int slot); + void folioq_unmark2(struct folio_queue *folioq, unsigned int slot); + void folioq_unmark3(struct folio_queue *folioq, unsigned int slot); + +And the marks can be queried by:: + + bool folioq_is_marked(const struct folio_queue *folioq, unsigned int slot); + bool folioq_is_marked2(const struct folio_queue *folioq, unsigned int slot); + bool folioq_is_marked3(const struct folio_queue *folioq, unsigned int slot); + +The marks can be used for any purpose and are not interpreted by this API. + + +Folio queue iteration +===================== + +A list of segments may be iterated over using the I/O iterator facility using +an ``iov_iter`` iterator of ``ITER_FOLIOQ`` type. The iterator may be +initialised with:: + + void iov_iter_folio_queue(struct iov_iter *i, unsigned int direction, + const struct folio_queue *folioq, + unsigned int first_slot, unsigned int offset, + size_t count); + +This may be told to start at a particular segment, slot and offset within a +queue. The iov iterator functions will follow the next pointers when advancing +and prev pointers when reverting when needed. + + +Lockless simultaneous production/consumption issues +=================================================== + +If properly managed, the list can be extended by the producer at the head end +and shortened by the consumer at the tail end simultaneously without the need +to take locks. The ITER_FOLIOQ iterator inserts appropriate barriers to aid +with this. + +Care must be taken when simultaneously producing and consuming a list. If the +last segment is reached and the folios it refers to are entirely consumed by +the IOV iterators, an iov_iter struct will be left pointing to the last segment +with a slot number equal to the capacity of that segment. The iterator will +try to continue on from this if there's another segment available when it is +used again, but care must be taken lest the segment got removed and freed by +the consumer before the iterator was advanced. + +It is recommended that the queue always contain at least one segment, even if +that segment has never been filled or is entirely spent. This prevents the +head and tail pointers from collapsing. + + +API Function Reference +====================== + +.. kernel-doc:: include/linux/folio_queue.h diff --git a/include/linux/folio_queue.h b/include/linux/folio_queue.h index 955680c3bb5f..af871405ae55 100644 --- a/include/linux/folio_queue.h +++ b/include/linux/folio_queue.h @@ -3,6 +3,12 @@ * * Copyright (C) 2024 Red Hat, Inc.

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.

One is specific to lan9303 and the other just happens to reproduce there. The first problem is that lan9303 is unique among DSA drivers in that it calls dev_get_drvdata() at "arbitrary runtime" (not probe, not shutdown, not remove): phy_state_machine() -> ... -> dsa_user_phy_read() -> ds->ops->phy_read() -> lan9303_phy_read() -> chip->ops->phy_read() -> lan9303_mdio_phy_read() -> dev_get_drvdata() But we never stop the phy_state_machine(), so it may continue to run after dsa_switch_shutdown(). Our common pattern in all DSA drivers is to set drvdata to NULL to suppress the remove() method that may come afterwards. But in this case it will result in an NPD. The second problem is that the way in which we set dp->conduit->dsa_ptr = NULL; is concurrent with receive packet processing. dsa_switch_rcv() checks once whether dev->dsa_ptr is NULL, but afterwards, rather than continuing to use that non-NULL value, dev->dsa_ptr is dereferenced again and again without NULL checks: dsa_conduit_find_user() and many other places. In between dereferences, there is no locking to ensure that what was valid once continues to be valid. Both problems have the common aspect that closing the conduit interface solves them. In the first case, dev_close(conduit) triggers the NETDEV_GOING_DOWN event in dsa_user_netdevice_event() which closes user ports as well. dsa_port_disable_rt() calls phylink_stop(), which synchronously stops the phylink state machine, and ds->ops->phy_read() will thus no longer call into the driver after this point. In the second case, dev_close(conduit) should do this, as per Documentation/networking/driver.rst: | Quiescence | ---------- | | After the ndo_stop routine has been called, the hardware must | not receive or transmit any data. All in flight packets must | be aborted. If necessary, poll or wait for completion of | any reset commands. So it should be sufficient to ensure that later, when we zeroize conduit->dsa_ptr, there will be no concurrent dsa_switch_rcv() call on this conduit. The addition of the netif_device_detach() function is to ensure that ioctls, rtnetlinks and ethtool requests on the user ports no longer propagate down to the driver - we're no longer prepared to handle them. The race condition actually did not exist when commit 0650bf52b31f ("net: dsa: be compatible with masters which unregister on shutdown") first introduced dsa_switch_shutdown(). It was created later, when we stopped unregistering the user interfaces from a bad spot, and we just replaced that sequence with a racy zeroization of conduit->dsa_ptr (one which doesn't ensure that the interfaces aren't up).

Then commit cf9acc90c80ec ("net: virtio_net_hdr_to_skb: count transport header in UFO") while fixing one issue, allowed user space to cook a GSO packet with the following characteristic : IPv4 SKB_GSO_UDP, gso_size=3, skb->len = 28. When this packet arrives in qdisc_pkt_len_init(), we end up with hdr_len = 28 (IPv4 header + UDP header), matching skb->len Then the following sets gso_segs to 0 : gso_segs = DIV_ROUND_UP(skb->len - hdr_len, shinfo->gso_size); Then later we set qdisc_skb_cb(skb)->pkt_len to back to zero :/ qdisc_skb_cb(skb)->pkt_len += (gso_segs - 1) * hdr_len; This leads to the following crash in fq_codel [1] qdisc_pkt_len_init() is best effort, we only want an estimation of the bytes sent on the wire, not crashing the kernel. This patch is fixing this particular issue, a following one adds more sanity checks for another potential bug.

This occurs because the pskb_network_may_pull function fails due to the packet's insufficient length. For example, if only the okey option is specified for the tunnel device, original (before encapsulation) packets smaller than 28 bytes (including the IPv4 header) will be dropped. This happens because the required length is calculated relative to the network header, not the skb->head. Here is how the required length is computed and checked: * The pull_len variable is set to 28 bytes, consisting of: * IPv4 header: 20 bytes * GRE header with Key field: 8 bytes * The pskb_network_may_pull function adds the network offset, shifting the checkable space further to the beginning of the network header and extending it to the beginning of the packet. As a result, the end of the checkable space occurs beyond the actual end of the packet. Instead of ensuring that 28 bytes are present in skb->head, the function is requesting these 28 bytes starting from the network header. For small packets, this requested length exceeds the actual packet size, causing the check to fail and the packets to be dropped. This issue affects both locally originated and forwarded packets in DMVPN-like setups. How to reproduce (for local originated packets): ip link add dev gre1 type gre ikey 1.9.8.4 okey 1.9.8.4 \ local remote 0.0.0.0 ip link set mtu 1400 dev gre1 ip link set up dev gre1 ip address add 192.168.13.1/24 dev gre1 ip neighbor add 192.168.13.2 lladdr dev gre1 ping -s 1374 -c 10 192.168.13.2 tcpdump -vni gre1 tcpdump -vni 'ip proto 47' ip -s -s -d link show dev gre1 Solution: Use the pskb_may_pull function instead the pskb_network_may_pull.

Marc Zyngier encountered a boot failure resulting from this when building a (particularly cursed) configuration with LLVM, as he reported to the list: https://lore.kernel.org/linux-arm-kernel/86wmjwvatn.wl-maz@kernel.org/ In Marc's kernel configuration, the .head.text and .rodata.text sections end up more than 128MiB apart, requiring a veneer to branch between the two: | [mark@lakrids:~/src/linux]% usekorg 14.1.0 aarch64-linux-objdump -t vmlinux | grep -w _text | ffff800080000000 g .head.text 0000000000000000 _text | [mark@lakrids:~/src/linux]% usekorg 14.1.0 aarch64-linux-objdump -t vmlinux | grep -w primary_entry | ffff8000889df0e0 g .rodata.text 000000000000006c primary_entry, ... consequently, LLD inserts a position-dependent veneer for the branch from _stext (in .head.text) to primary_entry (in .rodata.text): | ffff800080000000 <_text>: | ffff800080000000: fa405a4d ccmp x18, #0x0, #0xd, pl // pl = nfrst | ffff800080000004: 14003fff b ffff800080010000 <__AArch64AbsLongThunk_primary_entry> ... | ffff800080010000 <__AArch64AbsLongThunk_primary_entry>: | ffff800080010000: 58000050 ldr x16, ffff800080010008 <__AArch64AbsLongThunk_primary_entry+0x8> | ffff800080010004: d61f0200 br x16 | ffff800080010008: 889df0e0 .word 0x889df0e0 | ffff80008001000c: ffff8000 .word 0xffff8000 ... and as this is executed early in boot before the kernel is mapped in TTBR1 this results in a silent boot failure. Fix this by passing '--pic-veneer' to the linker, which will cause the linker to use position-independent veneers, e.g. | ffff800080000000 <_text>: | ffff800080000000: fa405a4d ccmp x18, #0x0, #0xd, pl // pl = nfrst | ffff800080000004: 14003fff b ffff800080010000 <__AArch64ADRPThunk_primary_entry> ... | ffff800080010000 <__AArch64ADRPThunk_primary_entry>: | ffff800080010000: f004e3f0 adrp x16, ffff800089c8f000 <__idmap_text_start> | ffff800080010004: 91038210 add x16, x16, #0xe0 | ffff800080010008: d61f0200 br x16 I've opted to pass '--pic-veneer' unconditionally, as: * In addition to solving the boot failure, these sequences are generally nicer as they require fewer instructions and don't need to perform data accesses. * While the position-independent veneer sequences have a limited +/-2GiB range, this is not a new restriction. Even kernels built with CONFIG_RELOCATABLE=n are limited to 2GiB in size as we have several structues using 32-bit relative offsets and PPREL32 relocations, which are similarly limited to +/-2GiB in range. These include extable entries, jump table entries, and alt_instr entries. * GNU LD defaults to using position-independent veneers, and supports the same '--pic-veneer' option, so this change is not expected to adversely affect GNU LD.

The "count" here comes from the user and on 32bit systems, it leads to integer wrapping when we pass it to compute_user_elem_size(): alloc_size = compute_user_elem_size(private_size, count); However, the integer over is harmless because later "count" is checked when we pass it to snd_ctl_new(): err = snd_ctl_new(&kctl, count, access, file); These days as part of kernel hardening we're trying to avoid integer overflows when they affect size_t type. So to avoid the integer overflow copy the check from snd_ctl_new() and do it at the start of the snd_ctl_elem_add() function as well.

But it uses a buffer allocated with kvm_host_sve_max_vl, the maximum VL shared by all PEs in the system. This means that if we run on a system where the maximum VLs are not consistent, we will overflow the buffer on PEs which support larger VLs. Since the host will not currently attempt to make use of non-shared VLs, fix this by explicitly setting the EL2 VL to be the maximum shared VL when we save and restore.

But in the meantime, Joey has stepped up and did a really good job reviewing some terrifying patch series. Having talked with the interested parties, it appears that James is unlikely to have time for KVM in the near future, and that Joey is willing to take more responsibilities. So let's appoint Joey as an official reviewer, and give James some breathing space, as well as my personal thanks. I'm sure he will be back one way or another!

This is because the clock controller first grabs the prepare_lock mutex and then performs the prepare operation, including its I2C access. The I2C access resumes this I2C bus controller via .runtime_resume callback, which calls clk_prepare_enable(), which attempts to grab the prepare_lock mutex again and deadlocks. Since the clock are already prepared since probe() and unprepared in remove(), use simple clk_enable()/clk_disable() calls to enable and disable the clock on runtime suspend and resume, to avoid hitting the prepare_lock mutex.

Due to this side effect, we would never release kobject defined for kmem cache and leak the associated memory. The issue here's with the use of __is_defined() macro in kmem_cache_ release(). The __is_defined() macro expands to __take_second_arg( arg1_or_junk 1, 0). If "arg1_or_junk" is defined to 1 then it expands to __take_second_arg(0, 1, 0) and returns 1. If "arg1_or_junk" is NOT defined to any value then it expands to __take_second_arg(... 1, 0) and returns 0. In this particular issue, SLAB_SUPPORTS_SYSFS is defined without any associated value and that causes __is_defined(SLAB_SUPPORTS_SYSFS) to always evaluate to 0 and hence it would never invoke sysfs_slab_release().

This works as long as we're only ever modifying blocks, not changing the structure of the tree. However relocation does in fact change the structure of the tree. For example, if we are relocating a data extent, we will look up all the leaves that point to this data extent. We will then call do_relocation() on each of these leaves, which will COW down to the leaf and then update the file extent location. But, a key feature of do_relocation() is the pending list. This is all the pending nodes that we modified when we updated the file extent item. We will then process all of these blocks via finish_pending_nodes, which calls do_relocation() on all of the nodes that led up to that leaf. The purpose of this is to make sure we don't break sharing unless we absolutely have to. Consider the case that we have 3 snapshots that all point to this leaf through the same nodes, the initial COW would have created a whole new path. If we did this for all 3 snapshots we would end up with 3x the number of nodes we had originally. To avoid this we will cycle through each of the snapshots that point to each of these nodes and update their pointers to point at the new nodes. Once we update the pointer to the new node we will drop the node we removed the link for and all of its children via btrfs_drop_subtree(). This is essentially just btrfs_drop_snapshot(), but for an arbitrary point in the snapshot. The problem with this is that we will never reflect this in the backref cache. If we do this btrfs_drop_snapshot() for a node that is in the backref tree, we will leave the node in the backref tree. This becomes a problem when we change the transid, as now the backref cache has entire subtrees that no longer exist, but exist as if they still are pointed to by the same roots. In the best case scenario you end up with "adding refs to an existing tree ref" errors from insert_inline_extent_backref(), where we attempt to link in nodes on roots that are no longer valid. Worst case you will double free some random block and re-use it when there's still references to the block. This is extremely subtle, and the consequences are quite bad. There isn't a way to make sure our backref cache is consistent between transid's. In order to fix this we need to simply evict the entire backref cache anytime we cross transid's. This reduces performance in that we have to rebuild this backref cache every time we change transid's, but fixes the bug. This has existed since relocation was added, and is a pretty critical bug. There's a lot more cleanup that can be done now that this functionality is going away, but this patch is as small as possible in order to fix the problem and make it easy for us to backport it to all the kernels it needs to be backported to. Followup series will dismantle more of this code and simplify relocation drastically to remove this functionality. We have a reproducer that reproduced the corruption within a few minutes of running. With this patch it survives several iterations/hours of running the reproducer.

In this case the destination will fail to apply the clone operation because its end offset is not sector size aligned and it ends before the current size of the file. Sending the truncate operation always happens when we finish processing an inode, after we process all its extents (and xattrs, names, etc). So fix this by ensuring the file has a valid size before we send a clone operation for an unaligned extent that ends at the final i_size of the file. The size we truncate to matches the start offset of the clone range but it could be any value between that start offset and the final size of the file since the clone operation will expand the i_size if the current size is smaller than the end offset. The start offset of the range was chosen because it's always sector size aligned and avoids a truncation into the middle of a page, which results in dirtying the page due to filling part of it with zeroes and then making the clone operation at the receiver trigger IO.

Then we continue the error path cleanup in btrfs_balance() by calling reset_balance_state() which will call del_balance_item() to fully delete the balance item in the root tree. However during the small window between set_reloc_contrl() and unset_reloc_control(), we can have a subvolume tree update and created a reloc_root for that subvolume. Then we go into the final btrfs_commit_transaction() of del_balance_item(), and into btrfs_update_reloc_root() inside commit_fs_roots(). That function checks if fs_info->reloc_ctl is in the merge_reloc_tree stage, but since fs_info->reloc_ctl is NULL, it results a NULL pointer dereference. [FIX] Just add extra check on fs_info->reloc_ctl inside btrfs_update_reloc_root(), before checking fs_info->reloc_ctl->merge_reloc_tree. That DEAD_RELOC_TREE handling is to prevent further modification to the reloc tree during merge stage, but since there is no reloc_ctl at all, we do not need to bother that.

Syzbot reported a case where a fixup worker resulted in a crash when doing a delayed iput on its inode while attempting to wake up the cleaner at btrfs_add_delayed_iput(), because the task_struct of the cleaner kthread was already freed. This can happen during unmount because we don't wait for any fixup workers still running before we call kthread_stop() against the cleaner kthread, which stops and free all its resources.

So fix this by moving the logic to compute the right kernel stack into a header.

This works as expected, per se, but there have been a few cases where we forgot to set this flag while preferred_dacs table is already set up. It ended up with incorrect wiring and made us wondering why it doesn't work. Basically, when the preferred_dacs table is provided, it means that the driver really wants to wire up to follow that. That is, the presence of the preferred_dacs table itself is already a "do-it" flag. In this patch, we simply replace the evaluation of obey_preferred_dacs flag with the presence of preferred_dacs table for fixing the misbehavior. Another patch to drop of the obsoleted flag will follow.

On situations like ftruncate, udf_extend_file() can now detect errors and bail out early without resorting to checking for particular offsets and assuming internal behavior of these functions.

This scenario shows that all notification groups are in principle prone to this kind of a deadlock (previously, we considered only fanotify and dnotify to be problematic for other reasons) so make sure all allocations under group->mark_mutex happen with GFP_NOFS.

It avoids that the tx() runs into use-after-free. Then Nicolai Stange found more places in aoe have potential use-after-free problem with tx(). e.g. revalidate(), aoecmd_ata_rw(), resend(), probe() and aoecmd_cfg_rsp(). Those functions also use aoenet_xmit() to push packet to tx queue. So they should also use dev_hold() to increase the refcnt of skb->dev. On the other hand, moving dev_put() to tx() causes that the refcnt of skb->dev be reduced to a negative value, because corresponding dev_hold() are not called in revalidate(), aoecmd_ata_rw(), resend(), probe(), and aoecmd_cfg_rsp(). This patch fixed this issue.

The problem that the commit e6a3531dd542cb127c8de32ab1e54a48ae19962b fixes was reported as a security bug, but Google engineers working on Android and ChromeOS didn't want to change the default behavior, they want to get -EIO rather than restarting the system, so I am reverting that commit. Note also that calling machine_restart from the I/O handling code is potentially unsafe (the reboot notifiers may wait for the bio that triggered the restart), but Android uses the reboot notifiers to store the reboot reason into the PMU microcontroller, so machine_restart must be used.

The test_kfree_rcu test invokes kfree_rcu() and boot sequence inspection showed the runner for built-in kunit tests kunit_run_all_tests() is called before setting system_state to SYSTEM_RUNNING and calling rcu_end_inkernel_boot(), so this seems like a likely cause. So while I was unable to reproduce the problem myself, skipping the test when the slub_kunit module is built-in should avoid the issue. An alternative fix that was moving the call to kunit_run_all_tests() a bit later in the boot was tried, but has broken tests with functions marked as __init due to free_initmem() already being done.

Now, whilst the collector will normally end up running at least once after this bit is set just because it takes a while to process all the write subrequests before the collector runs out of subrequests, there exists the possibility that the issuing thread will be forced to sleep and the collector thread will clean up all the subrequests before ALL_QUEUED gets set. In such a case, the collector thread will not get triggered again and will never clear NETFS_RREQ_IN_PROGRESS thus leaving a request uncompleted and causing a potential futute hang. Fix this by scheduling the write collector if all the subrequest queues are empty (and thus no writes pending issuance). Note that we'd do this ideally before queuing the subrequest, but in the case of buffered writeback, at least, we can't find out that we've run out of folios until after we've called writeback_iter() and it has returned NULL - at which point we might not actually have any subrequests still under construction.

The fix seems leading to regressions for other systems. Also, the way to check the presence of IOMMU via get_dma_ops() isn't reliable and it's no longer applicable for 6.12. After all, it's no right fix, so let's revert it at first. To be noted, the PCM buffer allocation has been changed to try the continuous pages at first since 6.12, so the problem could be already addressed without this hackish workaround.

However the battery hook provider cannot know that, so it will later call battery_hook_unregister() on the already unregistered battery hook, resulting in a crash. Fix this by using the list head to mark already unregistered battery hooks as already being unregistered so that they can be ignored by battery_hook_unregister().

It should be caused by the write function is not successfully returned before the system suspend and the return value get messed when waking up. As a result, It may be better to check the time passed of those few instructions to determine whether the suspend is executed correctly for it is pretty hard to execute those few lines for 5 seconds. The timer to wake up the system is set to expire after 5 seconds and no re-arm. If the timer remaining time is 0 second and 0 nano secomd, it means the timer expired and wake the system up. Otherwise, the system could be considered to enter the suspend state failed if there is any remaining time. After appling this patch, the test would not fail for it believes the system does not go to suspend by mistake. It now could continue to the rest part of the test after suspend.

Unlike the parisc case, here we have an extra twist - asm/mmu.h has an implicit dependency on struct pt_regs, and in some users that used to be satisfied by include of asm/ptrace.h from asm/unaligned.h (note that asm/mmu.h itself did _not_ pull asm/unaligned.h - it relied upon the users having pulled asm/unaligned.h before asm/mmu.h got there). Seeing that asm/mmu.h only wants struct pt_regs * arguments in an extern, just pre-declare it there - less brittle that way. With that done _all_ asm/unaligned.h instances are reduced to include of asm-generic/unaligned.h and can be removed - unaligned.h is in mandatory-y in include/asm-generic/Kbuild. What's more, we can move asm-generic/unaligned.h to linux/unaligned.h and switch includes of to ; that's better off as an auto-generated commit, though, to be done by Linus at -rc1 time next cycle.
