The original patchset[1] used pr_warn_ratelimited(), however there were concerns about the degree of spam in the kernel log[2,3]. The resulting inability to detect every case was flagged as an issue at the time[4]. While we could come up with an alternative rate-limiting scheme such as only outputting the message if vm.memfd_noexec has been modified, or only outputting the message once for a given task, these alternatives have downsides that don't make sense given how low-stakes a single kernel warning message is. Switching to pr_info_ratelimited() instead should be fine -- it's possible some monitoring tool will be unhappy with a stream of warning-level messages but there's already plenty of info-level message spam in dmesg.

Otherwise, a small dependency change can result in spurious errors. For programs that don't use executable memfds, passing MFD_NOEXEC_SEAL is functionally a no-op and thus having the same In addition, every failure under vm.memfd_noexec=2 needs to print to the kernel log so that userspace can figure out where the error came from. The concerns about pr_warn_ratelimited() spam that caused the switch to pr_warn_once()[1,2] do not apply to the vm.memfd_noexec=2 case. This is a user-visible API change, but as it allows programs to do something that would be blocked before, and the sysctl itself was broken and recently released, it seems unlikely this will cause any issues.

Allow to specify GPIO or modem control line function in the device tree, and for each of the ports (A or B). Do so by using the new device-tree property named "nxp,modem-control-line-ports" (property added in separate patch).

The values of FP/SIMD registers in the core dump file come from the thread.fpu. However, kernel saves the FP/SIMD registers only before scheduling out the process. If no process switch happens during the exception handling, kernel will not have a chance to save the latest values of FP/SIMD registers. So it may cause their values in the core dump file incorrect. To solve this problem, force fpr_get()/simd_get() to save the FP/SIMD registers into the thread.fpu if the target task equals the current task.

This code was previously part of the VIDEO_IPU3_CIO2 driver, which could be built-in or a loadable module, but after the move it turned into a builtin-only driver. This fails to link when the I2C subsystem is a module: x86_64-linux-ld: drivers/media/pci/intel/ipu-bridge.o: in function `ipu_bridge_unregister_sensors': ipu-bridge.c:(.text+0x50): undefined reference to `i2c_unregister_device' x86_64-linux-ld: drivers/media/pci/intel/ipu-bridge.o: in function `ipu_bridge_init': ipu-bridge.c:(.text+0x9c9): undefined reference to `i2c_acpi_new_device_by_fwnode' In general, drivers should not have to be built-in, so change the option to a tristate with the corresponding dependency. This in turn opens a new problem with the dependency, as the IPU bridge can be a loadable module while the ipu3 driver itself is built-in, producing a new link failure: 86_64-linux-ld: drivers/media/pci/intel/ipu3/ipu3-cio2.o: in function `cio2_pci_probe': ipu3-cio2.c:(.text+0x197e): undefined reference to `ipu_bridge_init' In order to fix this, restore the old Kconfig option that controlled the ipu bridge driver before it was split out, but make it select a hidden symbol that now corresponds to the bridge driver. When other drivers get added that share ipu-bridge, this should cover all corner cases, and allow any combination of them to be built-in or modular.

We use the value from the SPR_MSR_UNC_CBO_CONFIG MSR to replace the one from the discovery table: 38776cc45eb7 ("perf/x86/uncore: Correct the number of CHAs on SPR") Unfortunately, the SPR_MSR_UNC_CBO_CONFIG isn't available for the EMR XCC (Always returns 0), but the above firmware bug doesn't impact the EMR XCC. Don't let the value from the MSR replace the existing value from the discovery table.

Commit 85d07c556216 ("USB: core: Unite old scheme and new scheme descriptor reads") altered the way USB devices are enumerated following detection, and in the process it messed up the initialization of SuperSpeed (or faster) devices: [ 31.650759] usb 2-1: new SuperSpeed Plus Gen 2x1 USB device number 2 using xhci_hcd [ 31.663107] usb 2-1: device descriptor read/8, error -71 [ 31.952697] usb 2-1: new SuperSpeed Plus Gen 2x1 USB device number 3 using xhci_hcd [ 31.965122] usb 2-1: device descriptor read/8, error -71 [ 32.080991] usb usb2-port1: attempt power cycle ... The problem was caused by the commit forgetting that in SuperSpeed or faster devices, the device descriptor uses a logarithmic encoding of the bMaxPacketSize0 value. (For some reason I thought the 255 case in the switch statement was meant for these devices, but it isn't -- it was meant for Wireless USB and is no longer needed.) We can fix the oversight by testing for buf->bMaxPacketSize0 = 9 (meaning 512, the actual maxpacket size for ep0 on all SuperSpeed devices) and straightening out the logic that checks and adjusts our initial guesses of the maxpacket value.

Prior to commit 45bf39f8df7f ("USB: core: Don't hold device lock while reading the "descriptors" sysfs file") this race couldn't occur, because the routines were mutually exclusive thanks to the device locking. Removing that locking from read_descriptors() exposed it to the race. The best way to fix the bug is to keep hub_port_init() from changing udev->descriptor once udev has been initialized and registered. Drivers expect the descriptors stored in the kernel to be immutable; we should not undermine this expectation. In fact, this change should have been made long ago. So now hub_port_init() will take an additional argument, specifying a buffer in which to store the device descriptor it reads. (If udev has not yet been initialized, the buffer pointer will be NULL and then hub_port_init() will store the device descriptor in udev as before.) This eliminates the data race responsible for the out-of-bounds read. The changes to hub_port_init() appear more extensive than they really are, because of indentation changes resulting from an attempt to avoid writing to other parts of the usb_device structure after it has been initialized. Similar changes should be made to the code that reads the BOS descriptor, but that can be handled in a separate patch later on. This patch is sufficient to fix the bug found by syzbot.

The usb_get_device_descriptor() routine reads the device descriptor from the udev device and stores it directly in udev->descriptor. This interface is error prone, because the USB subsystem expects in-memory copies of a device's descriptors to be immutable once the device has been initialized. The interface is changed so that the device descriptor is left in a kmalloc-ed buffer, not copied into the usb_device structure. A pointer to the buffer is returned to the caller, who is then responsible for kfree-ing it. The corresponding changes needed in the various callers are fairly small.

In preparation for reworking the usb_get_device_descriptor() routine, it is desirable to unite the two different code paths responsible for initially determining endpoint 0's maximum packet size in a newly discovered USB device. Making this determination presents a chicken-and-egg sort of problem, in that the only way to learn the maxpacket value is to get it from the device descriptor retrieved from the device, but communicating with the device to retrieve a descriptor requires us to know beforehand the ep0 maxpacket size. In practice this problem is solved in two different ways, referred to in hub.c as the "old scheme" and the "new scheme". The old scheme (which is the approach recommended by the USB-2 spec) involves asking the device to send just the first eight bytes of its device descriptor. Such a transfer uses packets containing no more than eight bytes each, and every USB device must have an ep0 maxpacket size >= 8, so this should succeed. Since the bMaxPacketSize0 field of the device descriptor lies within the first eight bytes, this is all we need. The new scheme is an imitation of the technique used in an early Windows USB implementation, giving it the happy advantage of working with a wide variety of devices (some of them at the time would not work with the old scheme, although that's probably less true now). It involves making an initial guess of the ep0 maxpacket size, asking the device to send up to 64 bytes worth of its device descriptor (which is only 18 bytes long), and then resetting the device to clear any error condition that might have resulted from the guess being wrong. The initial guess is determined by the connection speed; it should be correct in all cases other than full speed, for which the allowed values are 8, 16, 32, and 64 (in this case the initial guess is 64). The reason for this patch is that the old- and new-scheme parts of hub_port_init() use different code paths, one involving usb_get_device_descriptor() and one not, for their initial reads of the device descriptor. Since these reads have essentially the same purpose and are made under essentially the same circumstances, this is illogical. It makes more sense to have both of them use a common subroutine. This subroutine does basically what the new scheme's code did, because that approach is more general than the one used by the old scheme. It only needs to know how many bytes to transfer and whether or not it is being called for the first iteration of a retry loop (in case of certain time-out errors). There are two main differences from the former code: We initialize the bDescriptorType field of the transfer buffer to 0 before performing the transfer, to avoid possibly accessing an uninitialized value afterward. We read the device descriptor into a temporary buffer rather than storing it directly into udev->descriptor, which the old scheme implementation used to do. Since the whole point of this first read of the device descriptor is to determine the bMaxPacketSize0 value, that is what the new routine returns (or an error code). The value is stored in a local variable rather than in udev->descriptor. As a side effect, this necessitates moving a section of code that checks the bcdUSB field for SuperSpeed devices until after the full device descriptor has been retrieved.

The data role swap causes the device to unregister all alt modes, however the usb hub will still send Attention messages even after failing to reregister the Alt Mode. type_altmode_attention currently does not verify whether or not a device's altmode partner exists, which results in a NULL pointer error when dereferencing the typec_altmode and typec_altmode_ops belonging to the altmode partner.

When sending Discover Identity messages to a Port Partner that uses Power Delivery v2 and SVDM v1, we currently send PD v2 messages with SVDM v2.0, expecting the port partner to respond with its highest supported SVDM version as stated in Section 6.4.4.2.3 in the Power Delivery v3 specification. However, sending SVDM v2 to some Power Delivery v2 port partners results in a NAK whereas sending SVDM v1 does not. NAK messages can be handled by the initiator (PD v3 section 6.4.4.2.5.1), and one solution could be to resend Discover Identity on a lower SVDM version if possible. But, Section 6.4.4.3 of PD v2 states that "A NAK response Should be taken as an indication not to retry that particular Command." Instead, we can set the SVDM version to the maximum one supported by the negotiated PD revision. When operating in PD v2, this obeys Section 6.4.4.2.3, which states the SVDM field "Shall be set to zero to indicate Version 1.0." In PD v3, the SVDM field "Shall be set to 01b to indicate Version 2.0."

Commit fb08a1908cb1 ("dax: simplify the dax_device <-> gendisk association") introduced new logic for gendisk association, requiring drivers to explicitly call dax_add_host() and dax_remove_host(). For dcssblk driver, some dax_remove_host() calls were missing, e.g. in device remove path. The commit also broke error handling for out_dax case in device add path, resulting in an extra put_device() w/o the previous get_device() in that case. This lead to stale xarray entries after device add / remove cycles. In the case when a previously used struct gendisk pointer (xarray index) would be used again, because blk_alloc_disk() happened to return such a pointer, the xa_insert() in dax_add_host() would fail and go to out_dax, doing the extra put_device() in the error path. In combination with an already flawed error handling in dcssblk (device_register() cleanup), which needs to be addressed in a separate patch, this resulted in a missing device_del() / klist_del(), and eventually in the kernel crash with list_add corruption on a subsequent device_add() / klist_add(). Fix this by adding the missing dax_remove_host() calls, and also move the put_device() in the error path to restore the previous logic.

The Instruction Fetch (IF) units on current AMD Zen-based systems do not guarantee a synchronous #MC is delivered for poison consumption errors. Therefore, MCG_STATUS[EIPV|RIPV] will not be set. However, the microarchitecture does guarantee that the exception is delivered within the same context. In other words, the exact rIP is not known, but the context is known to not have changed. There is no architecturally-defined method to determine this behavior. The Code Segment (CS) register is always valid on such IF unit poison errors regardless of the value of MCG_STATUS[EIPV|RIPV]. Add a quirk to save the CS register for poison consumption from the IF unit banks. This is needed to properly determine the context of the error. Otherwise, the severity grading function will assume the context is IN_KERNEL due to the m->cs value being 0 (the initialized value). This leads to unnecessary kernel panics on data poison errors due to the kernel believing the poison consumption occurred in kernel context.

All posix lock ops, for all lockspaces (gfs2 file systems) are sent to userspace (dlm_controld) through a single misc device. The dlm_controld daemon reads the ops from the misc device and sends them to other cluster nodes using separate, per-lockspace cluster api communication channels. The ops for a single lockspace are ordered at this level, so that the results are received in the same sequence that the requests were sent. When the results are sent back to the kernel via the misc device, they are again funneled through the single misc device for all lockspaces. When the dlm code in the kernel processes the results from the misc device, these results will be returned in the same sequence that the requests were sent, on a per-lockspace basis. A recent change in this request/reply matching code missed the "per-lockspace" check (fsid comparison) when matching request and reply, so replies could be incorrectly matched to requests from other lockspaces.

For a device with no Power Management Capability, pci_power_up() previously returned 0 (success) if the platform was able to put the device in D0, which led to pci_set_full_power_state() trying to read PCI_PM_CTRL, even though it doesn't exist. Since dev->pm_cap == 0 in this case, pci_set_full_power_state() actually read the wrong register, interpreted it as PCI_PM_CTRL, and corrupted dev->current_state. This led to messages like this in some cases: pci 0000:01:00.0: Refused to change power state from D3hot to D0 To prevent this, make pci_power_up() always return a negative failure code if the device lacks a Power Management Capability, even if non-PCI platform power management has been able to put the device in D0. The failure will prevent pci_set_full_power_state() from trying to access PCI_PM_CTRL.

When a Linux VM with an assigned PCI device runs on Hyper-V, if the PCI device driver is not loaded yet (i.e. MSI-X/MSI is not enabled on the device yet), doing a VM hibernation triggers a panic in hv_pci_restore_msi_msg() -> msi_lock_descs(&pdev->dev), because pdev->dev.msi.data is still NULL.

In certain systems with increased BMC interactions, the register values returned can be 0 for longer than 3 retries.

Syzbot reported a null-ptr-deref of sqd->thread inside io_sqpoll_wq_cpu_affinity. It turns out the sqd->thread can go away from under us during io_uring_register, in case the process gets a fatal signal during io_uring_register. It is not particularly hard to hit the race, and while I am not sure this is the exact case hit by syzbot, it solves it. Finally, checking ->thread is enough to close the race because we locked sqd while "parking" the thread, thus preventing it from going away. I reproduced it fairly consistently with a program that does: int main(void) { ... io_uring_queue_init(RING_LEN, &ring1, IORING_SETUP_SQPOLL); while (1) { io_uring_register_iowq_aff(ring, 1, &mask); } } Executed in a loop with timeout to trigger SIGTERM: while true; do timeout 1 /a.out ; done This will hit the following BUG() in very few attempts.

I3C masters are expected to support hot-join. This means at initialization time we might not yet discover any device and this should not be treated as a fatal error. During the DAA procedure which happens at probe time, if no device has joined, all CCC will be NACKed (from a bus perspective). This leads to an early return with an error code which fails the probe of the master. Let's avoid this by just telling the core through an I3C_ERROR_M2 return command code that no device was discovered, which is a valid situation. This way the master will no longer bail out and fail to probe for a wrong reason.

The minimum level of gcc supported for building the kernel is v5.1. v5.x releases of gcc emitted a three instruction sequence for -mprofile-kernel: mflr r0 std r0, 16(r1) bl _mcount It is only with the v6.x releases that gcc started emitting the two instruction sequence for -mprofile-kernel, omitting the second store instruction. With the older three instruction sequence, the actual ftrace location can be the 5th instruction into a function. Update the allowed offset for ftrace location from 12 to 16 to accommodate the same.

It is possible for xa_load() to observe a sibling entry pointing to another sibling entry. An example: Thread A: Thread B: xa_store_range(xa, entry, 188, 191, gfp); xa_load(xa, 191); entry = xa_entry(xa, node, 63); [entry is a sibling of 188] xa_store_range(xa, entry, 184, 191, gfp); if (xa_is_sibling(entry)) offset = xa_to_sibling(entry); entry = xa_entry(xas->xa, node, offset); [entry is now a sibling of 184] It is sufficient to go around this loop until we hit a non-sibling entry. Sibling entries always point earlier in the node, so we are guaranteed to terminate this search.

Xiongfeng reported and debugged a self deadlock of the task which initiates and controls a CPU hot-unplug operation vs. the CFS bandwidth timer. CPU1 CPU2 T1 sets cfs_quota starts hrtimer cfs_bandwidth 'period_timer' T1 is migrated to CPU2 T1 initiates offlining of CPU1 Hotplug operation starts ... 'period_timer' expires and is re-enqueued on CPU1 ... take_cpu_down() CPU1 shuts down and does not handle timers anymore. They have to be migrated in the post dead hotplug steps by the control task. T1 runs the post dead offline operation T1 is scheduled out T1 waits for 'period_timer' to expire T1 waits there forever if it is scheduled out before it can execute the hrtimer offline callback hrtimers_dead_cpu(). Cure this by delegating the hotplug control operation to a worker thread on an online CPU. This takes the initiating user space task, which might be affected by the bandwidth timer, completely out of the picture.

Currently, for double invoke call_rcu(), will dump rcu_head objects memory info, if the objects is not allocated from the slab allocator, the vmalloc_dump_obj() will be invoke and the vmap_area_lock spinlock need to be held, since the call_rcu() can be invoked in interrupt context, therefore, there is a possibility of spinlock deadlock scenarios.

MGLRU has a LRU list for each zone for each type (anon/file) in each generation: long nr_pages[MAX_NR_GENS][ANON_AND_FILE][MAX_NR_ZONES]; The min_seq (oldest generation) can progress independently for each type but the max_seq (youngest generation) is shared for both anon and file. This is to maintain a common frame of reference. In order for eviction to advance the min_seq of a type, all the per-zone lists in the oldest generation of that type must be empty. The eviction logic only considers pages from eligible zones for eviction or promotion. scan_folios() { ... for (zone = sc->reclaim_idx; zone >= 0; zone--) { ... sort_folio(); // Promote ... isolate_folio(); // Evict } ... } Consider the system has the movable zone configured and default 4 generations. The current state of the system is as shown below (only illustrating one type for simplicity): Type: ANON Zone DMA32 Normal Movable Device Gen 0 0 0 4GB 0 Gen 1 0 1GB 1MB 0 Gen 2 1MB 4GB 1MB 0 Gen 3 1MB 1MB 1MB 0 Now consider there is a GFP_KERNEL allocation request (eligible zone index <= Normal), evict_folios() will return without doing any work since there are no pages to scan in the eligible zones of the oldest generation. Reclaim won't make progress until triggered from a ZONE_MOVABLE allocation request; which may not happen soon if there is a lot of free memory in the movable zone. This can lead to OOM kills, although there is 1GB pages in the Normal zone of Gen 1 that we have not yet tried to reclaim. This issue is not seen in the conventional active/inactive LRU since there are no per-zone lists. If there are no (not enough) folios to scan in the eligible zones, move folios from ineligible zone (zone_index > reclaim_index) to the next generation. This allows for the progression of min_seq and reclaiming from the next generation (Gen 1). Qualcomm, Mediatek and raspberrypi [1] discovered this issue independently.

Blamed commit changed: ptr = kmalloc(size); if (ptr) size = ksize(ptr); to: size = kmalloc_size_roundup(size); ptr = kmalloc(size); This allowed various crash as reported by syzbot [1] and Kyle Zeng. Problem is that if @size is bigger than 0x80000001, kmalloc_size_roundup(size) returns 2^32. kmalloc_reserve() uses a 32bit variable (obj_size), so 2^32 is truncated to 0. kmalloc(0) returns ZERO_SIZE_PTR which is not handled by skb allocations.

Let’s assume the following situation: vq->packed.vring.num=4 vq->packed.next_avail_idx: 1 vq->packed.avail_wrap_counter: 0 Then the driver adds a descriptor chain containing 4 descriptors. We expect the following result with avail_wrap_counter flipped: vq->packed.next_avail_idx: 1 vq->packed.avail_wrap_counter: 1 But, the current implementation gives the following result: vq->packed.next_avail_idx: 1 vq->packed.avail_wrap_counter: 0 To reproduce the bug, you can set a packed queue size as small as possible, so that the driver is more likely to provide a descriptor chain with a length equal to the packed queue size. For example, in qemu run following commands: sudo qemu-system-x86_64 \ -enable-kvm \ -nographic \ -kernel "path/to/kernel_image" \ -m 1G \ -drive file="path/to/rootfs",if=none,id=disk \ -device virtio-blk,drive=disk \ -drive file="path/to/disk_image",if=none,id=rwdisk \ -device virtio-blk,drive=rwdisk,packed=on,queue-size=4,\ indirect_desc=off \ -append "console=ttyS0 root=/dev/vda rw init=/bin/bash" Inside the VM, create a directory and mount the rwdisk device on it. The rwdisk will hang and mount operation will not complete. This commit fixes the wrap counter error by flipping the packed.avail_wrap_counter, when start of descriptor chain equals to the end of descriptor chain (head == i).

For example it's not rare in the networking device where the number of queues could exceed the number of CPUs. Such case breaks the current affinity logic which is based on group_cpus_evenly() who assumes the number of CPUs are not less than the number of groups. This can trigger a warning[1]: if (ret >= 0) WARN_ON(nr_present + nr_others < numgrps); Fixing this by only build the affinity masks only when - Driver passes affinity descriptor, driver like virtio-blk can make sure to limit the number of queues when it exceeds the number of CPUs - Parent support affinity setting config ops This help to avoid the warning. More optimizations could be done on top.

Using this field to print a warning once detect a case where the same task is calling _begin() again before completing the preivous frequency transition via the _end(). However, there is a potential race condition in _end() and _begin() APIs while updating the field 'transition_task' of policy, the scenario is depicted below: Task A Task B /* 1st freq transition */ Invoke _begin() { ... ... } /* 2nd freq transition */ Invoke _begin() { ... //waiting for A to ... //clear ... //transition_ongoing ... //in _end() for ... //the 1st transition | Change the frequency | | Invoke _end() { | ... | ... | transition_ongoing = false; V transition_ongoing = true; transition_task = current; transition_task = NULL; ... //A overwrites the task ... //performing the transition ... //result in error warning. } To fix this race condition, the transition_lock of policy structure is now acquired before updating policy structure in _end() API. Which ensure that only one task can update the 'transition_task' field at a time.

However, if it is not able to find them it ends trying to walk resources of the ACPI namespace root object itself. This object has all-ones handle, which causes a NULL pointer dereference in the ACPI code (from dereferencing this pointer with an offset). This in turn causes an oops on boot with VMBus host implementations that do not provide Hyper-V MMIO ranges in their VMBus ACPI device or its ancestors. The QEMU VMBus implementation is an example of such implementation. I guess providing these ranges is optional, since all tested Windows versions seem to be able to use VMBus devices without them. Fix this by explicitly terminating the lookup at the ACPI namespace root object. Note that Linux guests under KVM/QEMU do not use the Hyper-V PV interface by default - they only do so if the KVM PV interface is missing or disabled.

This is bad because the LED_ON constant is equal to 1, and so when activating the tty LED trigger on a LED class device with max_brightness greater than 1, the LED is dimmer than it can be (when max_brightness is 255, the LED is very dimm indeed; some devices translate 1/255 to 0, so the LED is OFF all the time). Instead of directly setting brightness to a specific value, use the led_blink_set_oneshot() function from LED core to configure the blink. This function takes the current configured brightness as blink brightness if not zero, and max brightness otherwise. This also changes the behavior of the TTY LED trigger. Previously if rx/tx stats kept changing, the LED was ON all the time they kept changing. With this patch the LED will blink on TTY activity.

The threshold for each sensor is handled separately by the thermal framework, since each one is registered with its own thermal zone and trips. However, the temperature thresholds are configured on the controller, and therefore are shared between all sensors on that controller. When the temperature measured by the sensors is different enough to cause the thermal framework to configure different thresholds for each one, interrupts start triggering on sensors outside the last threshold configured. To address the issue, track the thresholds required by each sensor and only actually set the highest one in the hardware, and disable interrupts for all sensors outside the current configured range.

This leaves the register zeroed, which translates to a very high temperature for the low threshold. The interrupt for this threshold is then immediately triggered, and the state machine gets stuck, preventing any other temperature monitoring interrupts to ever trigger. (The same happens by not setting the Cold or Hot to Normal thresholds when using those) Set the unused threshold to a valid low value.

But better yet than addressing those issues, is to use the high/low offset interrupts instead. This way only two thresholds need to be managed, which have a simpler state machine, making them a better match to the thermal framework's high and low thresholds.

However, the "client" Skylakes* are now in this list: https://www.intel.com/content/www/us/en/support/articles/000022396/processors.html which means they are no longer included for new vulnerabilities here: https://www.intel.com/content/www/us/en/developer/topic-technology/software-security-guidance/processors-affected-consolidated-product-cpu-model.html or in other GDS documentation. Thus, they were not included in the original GDS mitigation patches. Mark SKYLAKE and SKYLAKE_L as vulnerable to GDS to match all the other Skylake CPUs (which include Kaby Lake). Also group the CPUs so that the ones that share the exact same vulnerabilities are next to each other. Last, move SRBDS to the end of each line. This makes it clear at a glance that SKYLAKE_X is unique. Of the five Skylakes, it is the only "server" CPU and has a different implementation from the clients of the "special register" hardware, making it immune to SRBDS. This makes the diff much harder to read, but the resulting table is worth it. I very much appreciate the report from Michael Zhivich about this issue. Despite what level of support a hardware vendor is providing, the kernel very much needs an accurate and up-to-date list of vulnerable CPUs. More reports like this are very welcome. * Client Skylakes are CPUID 406E3/506E3 which is family 6, models 0x4E and 0x5E, aka INTEL_FAM6_SKYLAKE and INTEL_FAM6_SKYLAKE_L.

In doing so, the code essentially went from a one conditional: if (a && b && c) warn(); to a three conditional: if (!a) return; if (!b) return; if (!c) return; warn(); But that conversion got the condition for the RT specific local_bh_blocked() wrong. The original condition was: !local_bh_blocked() but the conversion failed to negate it so it ended up as: if (!local_bh_blocked()) return false; This issue lay dormant until another fixup for the same commit was added in commit a7e282c77785 ("tick/rcu: Fix bogus ratelimit condition"). This commit realized the ratelimit was essentially set to zero instead of ten, and hence *no* softirq pending messages would ever be issued. Once this commit was backported via linux-stable, both the v6.1 and v6.4 preempt-rt kernels started printing out 10 instances of this at boot: NOHZ tick-stop error: local softirq work is pending, handler #80!!! Remove the negation and return when local_bh_blocked() evaluates to true to bring the correct behaviour back.

If siw_cm_alloc_work returns failure. In this case socket is not assoicated with cep so siw_cep_put can't be called by siw_socket_disassoc. We need to call siw_cep_put twice since cep->kref is increased once after it was initialized. 2. If siw_cm_queue_work can't find a work, which means siw_cep_get is not called in siw_cm_queue_work, so cep->kref is increased twice by siw_cep_get and when associate socket with cep after it was initialized. So we need to call siw_cep_put three times (one in siw_socket_disassoc). 3. siw_send_mpareqrep returns error, this scenario is similar as 2. So we need to remove one siw_cep_put in the error path.

The OV2680 supports manual gain and exposure control only for normal applications, no auto mode." And indeed testing with the atomisp_ov2680 fork of ov2680.c has shown that auto-exposure and auto-gain do not work. Note that the code setting the auto-exposure flag was broken, callers of ov2680_exposure_set() were directly passing !!ctrls->auto_exp->val as "bool auto_exp" value, but ctrls->auto_exp is a menu control with: enum v4l2_exposure_auto_type { V4L2_EXPOSURE_AUTO = 0, V4L2_EXPOSURE_MANUAL = 1, ... So instead of passing !!ctrls->auto_exp->val they should have been passing ctrls->auto_exp->val == V4L2_EXPOSURE_AUTO, iow the passed value was inverted of what it should have been. Also remove ov2680_g_volatile_ctrl() since without auto support the gain and exposure controls are not volatile. This also fixes the control values not being properly applied in ov2680_mode_set(). The 800x600 mode register-list also sets gain, exposure and vflip overriding the last set ctrl values. ov2680_mode_set() does call ov2680_gain_set() and ov2680_exposure_set() but did this before writing the mode register-list, so these values would still be overridden by the mode register-list. Add a v4l2_ctrl_handler_setup() call after writing the mode register-list to restore all ctrl values. Also remove the ctrls->gain->is_new check from ov2680_gain_set() so that the gain always gets restored properly. Last since ov2680_mode_set() now calls v4l2_ctrl_handler_setup(), remove the v4l2_ctrl_handler_setup() call after ov2680_mode_restore() since ov2680_mode_restore() calls ov2680_mode_set().

This causes the device to be permanently stuck with the BTN_TOOL_RUBBER tool after sending Eraser, as Invert is the only usage that can release the tool. In this state, Touch and Inrange are no longer reported to userspace, rendering the pen unusable. Prior to commit 87562fcd1342 ("HID: input: remove the need for HID_QUIRK_INVERT"), BTN_TOOL_RUBBER was never set and Eraser events were simply translated into BTN_TOUCH without causing an inconsistent state. Introduce HID_QUIRK_NOINVERT for such digitizers and detect them during hidinput_configure_usage(). This quirk causes the tool to be released as soon as Eraser is reported as not set.

This leads to issues when using bus-less or driver-less devices where the device might never get freed if a managed resource holds a reference to the device. This is happening in the DRM framework for example. We should thus call devres_release_all() in the device_del() function to make sure that the device-managed actions are properly executed when the device is unregistered, even if it has neither a bus nor a driver. This is effectively the same change than commit 2f8d16a996da ("devres: release resources on device_del()") that got reverted by commit a525a3ddeaca ("driver core: free devres in device_release") over memory leaks concerns. This patch effectively combines the two commits mentioned above to release the resources both on device_del() and device_release() and get the best of both worlds.

The cec_data_cancel() function is called with the adap->lock mutex held, and cec_transmit_msg() tries to take that same lock.

RoCE driver excludes direct wqe for wr-list by judging whether the number of wr is 1. For a wr-list where the second wr is a length-error atomic wr, the post-send driver handles the first wr and adds 1 to the wr number counter firstly. While handling the second wr, the driver finds out a length error and terminates the wr handle process, remaining the counter at 1. This causes the driver mistakenly judges there is only 1 wr and thus enters the direct wqe process, carrying the current length-error atomic wqe. This patch fixes the error by adding a judgement whether the current wr is a bad wr. If so, use the normal doorbell process but not direct wqe despite the wr number is 1.

No matter it is vdo or vpp. Then it still create a new pagetable in step d). The problem is "frstdata->bank[0]->m4u_dom" was not initialized. Then when d) enter, it still create a new one. In this patch, we create a new variable "share_dom" for this share pgtable case, it should be helpful for readable. and put all the share pgtable logic in the mtk_iommu_domain_finalise. In mt8195, the master of VPP-IOMMU probes before than VDO-IOMMU from its dtsi node sequence, we don't see this issue in it. Prepare for mt8188.

So, replace one-element array in struct irdma_qvlist_info with flexible-array member. A patch for this was sent a while ago[1]. However, it seems that, at the time, the changes were partially folded[2][3], and the actual flexible-array transformation was omitted. This patch fixes that.

To recover, the state of the wqe is restored to the state before the packet was sent so it can be resent. However, the routines that save and restore the state miss a significnt part of the variable state in the wqe, the dma struct which is used to process through the sge table. And, the state is not saved before the packet is built which modifies the dma struct. Under heavy stress testing with many QPs on a fast node sending large messages to a slow node dropped packets are observed and the resent packets are corrupted because the dma struct was not restored. This patch fixes this behavior and allows the test cases to succeed.

By investigating how the bug is introduced, we find it is really interesting as the old version parsing code starting from commit fd7255f51a13 ("[SCSI] iscsi: add sysfs attrs for uspace sync up") treated the nlattr as integer bytes instead of string and had length check in iscsi_copy_param(): if (ev->u.set_param.len != sizeof(uint32_t)) BUG(); But, since the commit a54a52caad4b ("[SCSI] iscsi: fixup set/get param functions"), the code treated the nlattr as C string while forgetting to add any strlen checks(), opening the possibility of an OOB access. Fix the potential OOB by adding the strlen() check before accessing the buf. If the data passes this check, all low-level set_param handlers can safely treat this buf as legal C string.

However, in other cases the length of nlattr payload is not checked before the payload is converted to other data structures. One example is iscsi_set_path() which converts the payload to type iscsi_path without any checks: params = (struct iscsi_path *)((char *)ev + sizeof(*ev)); Whereas iscsi_if_transport_conn() correctly checks the pdu_len: pdu_len = nlh->nlmsg_len - sizeof(*nlh) - sizeof(*ev); if ((ev->u.send_pdu.hdr_size > pdu_len) .. err = -EINVAL; To sum up, some code paths called in iscsi_if_recv_msg() do not check the length of the data (see below picture) and directly convert the data to another data structure.

When the client provides a zero gd_maxcount, then the Linux NFS server implementation encodes the da_layout_type field and then skips the da_addr_body field completely, proceeding directly to encode gdir_notification field. There does not appear to be an option in the specification to skip encoding da_addr_body. Moreover, Section 18.40.3 says: > If the client wants to just update or turn off notifications, it > MAY send a GETDEVICEINFO operation with gdia_maxcount set to zero. > In that event, if the device ID is valid, the reply's da_addr_body > field of the gdir_device_addr field will be of zero length. Since the layout drivers are responsible for encoding the da_addr_body field, put this fix inside the ->encode_getdeviceinfo methods.

There are several places not updating disk inode while putting inode into orphan area, such as ext4_add_nondir(), ext4_symlink() and whiteout in ext4_rename(). Fix it by updating inode into disk in all error branches of these places.

This is how we ended up occasionally double-freeing the scratch buffer, but also means we set a NULL pointer but non-zero length to the xdr scratch buffer. This results in an oops the first time decoding needs to copy something to scratch, which frequently happens when decoding READ_PLUS hole segments. I fix this by moving scratch handling into the pageio read code. I provide a function to allocate scratch space for decoding read replies, and free the scratch buffer when the nfs_pgio_header is freed.

This issue doesn't show up normally, because the clock framework will take care to not call set_rate when the clock rate is the same. However, when we reconfigure an upstream clock, the common code will call set_rate with the newly calculated rate on all children, e.g.: - sai5 is running normally and divides Audio PLL out by 16. - Audio PLL rate is increased by 32Hz (glitch-free kdiv change) - rates for children are recalculated and rates are set recursively - imx8m_clk_composite_divider_set_rate(sai5) is called with 32/16 = 2Hz more - imx8m_clk_composite_divider_set_rate computes same divider as before - divider register is written, so it restarts counting from zero and MCLK is briefly paused, so instead of e.g. 40ns, MCLK is low for 120ns. Some external clock consumers can be upset by such unexpected clock pauses, so let's make sure we only rewrite the divider value when the value to be written is actually different.

Add pcie_cap_lock spinlock into the struct pci_dev and use it to protect bit changes made in the RMW capability accessors. Protect only a selected set of registers by differentiating the RMW accessor internally to locked/unlocked variants using a wrapper which has the same signature as pcie_capability_clear_and_set_word().

If we race group addition and deletion calls, kvg instance may get freed by the time we get around to calling kvm_vfio_file_set_kvm(). Previous iterations of the code did not reference kvg->file outside of the critical section, but used a temporary variable. Still, they had similar problem of the file reference being owned by kvg structure and potential for kvm_vfio_group_del() dropping it before kvm_vfio_group_add() had a chance to complete. Fix this by moving call to kvm_vfio_file_set_kvm() under the protection of kv->lock. We already call it while holding the same lock when vfio group is being deleted, so it should be safe here as well.

However, of_overlay_apply() calls of_resolve_phandles() before init_overlay_changeset(). Hence if the overlay fails to apply due to an unresolved symbol, the overlay_changeset.cset.entries list is still uninitialized, and cleanup will crash with a NULL-pointer dereference in overlay_removal_is_ok(). Fix this by moving the call to of_changeset_init() from init_overlay_changeset() to of_overlay_fdt_apply(), where all other early initialization is done.

Only the portion of I/O still assigned to the original bio which was reduced by the split will be accounted for. This results in md iostat data sometimes showing I/O values far below the actual amount of data being sent through md. md_account_bio() needs to be called for all bio generated by the bio split. A simple example of the issue was generated using a raid0 device on partitions to the same device. Since all raid0 I/O then goes to one device, it makes it easy to see a gap between the md device and its sd storage. Reading an lvm device on top of the md device, the iostat output (some 0 columns and extra devices removed to make the data more compact) was: Device tps kB_read/s kB_wrtn/s kB_dscd/s kB_read md2 0.00 0.00 0.00 0.00 0 sde 0.00 0.00 0.00 0.00 0 md2 1364.00 411496.00 0.00 0.00 411496 sde 1734.00 646144.00 0.00 0.00 646144 md2 1699.00 510680.00 0.00 0.00 510680 sde 2155.00 802784.00 0.00 0.00 802784 md2 803.00 241480.00 0.00 0.00 241480 sde 1016.00 377888.00 0.00 0.00 377888 md2 0.00 0.00 0.00 0.00 0 sde 0.00 0.00 0.00 0.00 0 I/O was generated doing large direct I/O reads (12M) with dd to a linear lvm volume on top of the 4 leg raid0 device. The md2 reads were showing as roughly 2/3 of the reads to the sde device containing all of md2's raid partitions. The sum of reads to sde was 1826816 kB, which was the expected amount as it was the amount read by dd. With the patch, the total reads from md will match the reads from sde and be consistent with the amount of I/O generated.

Before this commit, we have split the bio, mapped and submitted each part. After this commit, we map only the first part of the split bio and submit the second part unmapped. Due to bio sorting in __submit_bio_noacct() this results in the following request ordering: 9,0 18 1181 0.525037895 15995 Q WS 1479315464 + 63392 Split off chunk-sized (1024 sectors) request: 9,0 18 1182 0.629019647 15995 X WS 1479315464 / 1479316488 Request is unaligned to the chunk so it's split in raid0_make_request(). This is the first part mapped and punted to bio_list: 8,0 18 7053 0.629020455 15995 A WS 739921928 + 1016 <- (9,0) 1479315464 Now raid0_make_request() returns, second part is postponed on bio_list. __submit_bio_noacct() resorts the bio_list, mapped request is submitted to the underlying device: 8,0 18 7054 0.629022782 15995 G WS 739921928 + 1016 Now we take another request from the bio_list which is the remainder of the original huge request. Split off another chunk-sized bit from it and the situation repeats: 9,0 18 1183 0.629024499 15995 X WS 1479316488 / 1479317512 8,16 18 6998 0.629025110 15995 A WS 739921928 + 1016 <- (9,0) 1479316488 8,16 18 6999 0.629026728 15995 G WS 739921928 + 1016 ... 9,0 18 1184 0.629032940 15995 X WS 1479317512 / 1479318536 [libnetacq-write] 8,0 18 7059 0.629033294 15995 A WS 739922952 + 1016 <- (9,0) 1479317512 8,0 18 7060 0.629033902 15995 G WS 739922952 + 1016 ... This repeats until we consume the whole original huge request. Now we finally get to processing the second parts of the split off requests (in reverse order): 8,16 18 7181 0.629161384 15995 A WS 739952640 + 8 <- (9,0) 1479377920 8,0 18 7239 0.629162140 15995 A WS 739952640 + 8 <- (9,0) 1479376896 8,16 18 7186 0.629163881 15995 A WS 739951616 + 8 <- (9,0) 1479375872 8,0 18 7242 0.629164421 15995 A WS 739951616 + 8 <- (9,0) 1479374848 ... I guess it is obvious that this IO pattern is extremely inefficient way to perform sequential IO. It also makes bio_list to grow to rather long lengths. Change raid0_make_request() to map both parts of the split bio. Since we know we are provided with at most chunk-sized bios, we will always need to split the incoming bio at most once.

The field is initialized by ioc_pd_init() and never cleared. The NULL deref is caused by blkcg_activate_policy() installing blkg_policy_data before initializing it. blkcg_activate_policy() was doing the following: 1. Allocate pd's for all existing blkg's and install them in blkg->pd[]. 2. Initialize all pd's. 3. Online all pd's. blkcg_activate_policy() only grabs the queue_lock and may release and re-acquire the lock as allocation may need to sleep. ioc_weight_write() grabs blkcg->lock and iterates all its blkg's. The two can race and if ioc_weight_write() runs during #1 or between #1 and #2, it can encounter a pd which is not initialized yet, leading to crash.

The only ordering requirement is that parent blkgs to be initialized and onlined before children, which is guaranteed from the walking order. Let's fix the bug by allocating, initializing and onlining pd for each blkg and holding blkcg->lock over initialization and onlining. This ensures that an installed blkg is always fully initialized and onlined removing the the race window.

For lack of better documentation these voltages are often copied as-is from the vendor device tree, without much extra thought. Unfortunately, the voltages in the vendor device trees are often misleading or even wrong, e.g. because: - There is a large voltage range allowed and the actual voltage is only set somewhere hidden in some messy vendor driver. This is often the case for pm8916_{l14,l15,l16} because they have a broad range of 1.8-3.3V by default. - The voltage is actually wrong but thanks to the voltage constraints in the RPM firmware it still ends up applying the correct voltage. To have proper regulator constraints it is important to review them in context of the usage. The current setup in the MSM8916 device trees makes this quite hard because each device duplicates the standard voltages for components of the SoC and mixes those with minor device-specific additions and dummy voltages for completely unused regulators. The actual usage of the regulators for the SoC components is in msm8916-pm8916.dtsi, so it can and should also define the related voltage constraints. These are not board-specific but defined in the APQ8016E/PM8916 Device Specification. The board DT can then focus on describing the actual board-specific regulators, which makes it much easier to review and spot potential mistakes there. Note that this commit does not make any functional change. All used regulators still have the same regulator constraints as before. Unused regulators do not have regulator constraints anymore because most of these were too broad or even entirely wrong. They should be added back with proper voltage constraints when there is an actual usage.

Unfortunately it turns out that Qualcomm's voltages are slightly off as well and do not match the voltage constraints applied by the RPM firmware. This means that we sometimes request a specific voltage but the RPM firmware actually applies a much lower or higher voltage. This is particularly critical for pm8916_l11 which is used as SD card VMMC regulator: The SD card can choose a voltage from the current range of 1.8 - 2.95V. If it chooses to run at 1.8V we pretend that this is fine but the RPM firmware will still silently end up configuring 2.95V. This can be easily reproduced with a multimeter or by checking the SPMI hardware registers of the regulator. Fix this by making the voltages match the actual "specified range" in the PM8916 Device Specification which is enforced by the RPM firmware.

For a mmc device (one hw queue, deadline I/O scheduler): q->nr_requests = sched_tags = 128, so according to the previous calculation method, dd->async_depth = data->shallow_depth = 96, and the platform is 64bits with 8 cpus, sched_tags.bitmap_tags.sb.shift=5, sb.maps[]=32/32/32/32, 32 is smaller than 96, whether it is a read or a write I/O, tags can be allocated to the maximum range each time, which has not throttling effect. In addition, refer to the methods of bfg/kyber I/O scheduler, limit ratiois are calculated base on sched_tags.bitmap_tags.sb.shift. This patch can throttle write requests really.

Those observations have been confirmed with failures from kms_pwrite_crc Intel GPU test that verifies data coherency of DRM frame buffer objects using hardware CRC checksums calculated by display controllers, exposed to userspace via debugfs. Affected processing paths have then been identified with new IGT test variants that mmap the objects using different methods and caching modes [1]. When running as a Xen PV guest, Linux uses Xen provided PAT configuration which is different from its native one. In particular, Xen specific PTE encoding of write-combining caching, likely used by graphics applications, differs from the Linux default one found among statically defined minimal set of supported modes. Since Xen defines PTE encoding of the WC mode as _PAGE_PAT, it no longer belongs to the minimal set, depends on correct handling of _PAGE_PAT bit, and can be mismatched with write-back caching. When a user calls mmap() for a DRM buffer object, DRM device specific .mmap file operation, called from mmap_region(), takes care of setting PTE encoding bits in a vm_page_prot field of an associated virtual memory area structure. Unfortunately, _PAGE_PAT bit is not preserved when the vma's .vm_flags are then applied to .vm_page_prot via vm_set_page_prot(). Bits to be preserved are determined with _PAGE_CHG_MASK symbol that doesn't cover _PAGE_PAT. As a consequence, WB caching is requested instead of WC when running under Xen (also, WP is silently changed to WT, and UC downgraded to UC_MINUS). When running on bare metal, WC is not affected, but WP and WT extra modes are unintentionally replaced with WC and UC, respectively. WP and WT modes, encoded with _PAGE_PAT bit set, were introduced by commit 281d4078bec3 ("x86: Make page cache mode a real type"). Care was taken to extend _PAGE_CACHE_MASK symbol with that additional bit, but that symbol has never been used for identification of bits preserved when applying page protection flags. Support for all cache modes under Xen, including the problematic WC mode, was then introduced by commit 47591df50512 ("xen: Support Xen pv-domains using PAT"). The issue needs to be fixed by including _PAGE_PAT bit into a bitmask used by pgprot_modify() for selecting bits to be preserved. We can do that either internally to pgprot_modify() (as initially proposed), or by making _PAGE_PAT a part of _PAGE_CHG_MASK. If we go for the latter then, since _PAGE_PAT is the same as _PAGE_PSE, we need to note that _HPAGE_CHG_MASK -- a huge pmds' counterpart of _PAGE_CHG_MASK, introduced by commit c489f1257b8c ("thp: add pmd_modify"), defined as (_PAGE_CHG_MASK | _PAGE_PSE) -- will no longer differ from _PAGE_CHG_MASK. If such modification of _PAGE_CHG_MASK was irrelevant to its users then one might wonder why that new _HPAGE_CHG_MASK symbol was introduced instead of reusing the existing one with that otherwise irrelevant bit (_PAGE_PSE in that case) added. Add _PAGE_PAT to _PAGE_CHG_MASK and _PAGE_PAT_LARGE to _HPAGE_CHG_MASK for symmetry. Split out common bits from both symbols to a common symbol for clarity.

But dquot_transfer() breaks this assumption. We call dquot_transfer() to drop the last reference of dquot and add it to free_dquots, but there may still be other users using the dquot at this time, as shown in the function graph below: cpu1 cpu2 _________________|_________________ wb_do_writeback CHOWN(1) ... ext4_da_update_reserve_space dquot_claim_block ... dquot_mark_dquot_dirty // try to dirty old quota test_bit(DQ_ACTIVE_B, &dquot->dq_flags) // still ACTIVE if (test_bit(DQ_MOD_B, &dquot->dq_flags)) // test no dirty, wait dq_list_lock ... dquot_transfer __dquot_transfer dqput_all(transfer_from) // rls old dquot dqput // last dqput dquot_release clear_bit(DQ_ACTIVE_B, &dquot->dq_flags) atomic_dec(&dquot->dq_count) put_dquot_last(dquot) list_add_tail(&dquot->dq_free, &free_dquots) // add the dquot to free_dquots if (!test_and_set_bit(DQ_MOD_B, &dquot->dq_flags)) add dqi_dirty_list // add released dquot to dirty_list This can cause various issues, such as dquot being destroyed by dqcache_shrink_scan() after being added to free_dquots, which can trigger a UAF in dquot_mark_dquot_dirty(); or after dquot is added to free_dquots and then to dirty_list, it is added to free_dquots again after dquot_writeback_dquots() is executed, which causes the free_dquots list to be corrupted and triggers a UAF when dqcache_shrink_scan() is called for freeing dquot twice. As Honza said, we need to fix dquot_transfer() to follow the guarantees dquot_srcu should provide. But calling synchronize_srcu() directly from dquot_transfer() is too expensive (and mostly unnecessary). So we add dquot whose last reference should be dropped to the new global dquot list releasing_dquots, and then queue work item which would call synchronize_srcu() and after that perform the final cleanup of all the dquots on releasing_dquots.

Mode set callback is called only once during boot in this scenario, while calls to enable/disable callbacks are balanced afterwards. The driver doesn't work unless userspace calls modeset before enabling the CRTC/connector. This patch moves enabling of the DSI host from mode_set into pre_enable callback, and removes some old hacks where this bridge driver is directly calling into other bridge driver's callbacks. pre_enable_prev_first flag is set on the panel's bridge so that panel drivers will get their prepare function called between DSI host's pre_enable and enable callbacks, so that they get a chance to perform panel setup while DSI host is already enabled in command mode. Otherwise panel's prepare would be called before DSI host is enabled, and any DSI communication used in prepare callback would fail. With all these changes, the enable/disable sequence is now well balanced, and host's and panel's callbacks are called in proper order documented in the drm_panel API documentation without needing the old hacks. (Mainly that panel->prepare is called when DSI host is ready to allow the panel driver to send DSI commands and vice versa during disable.) Tested on Pinephone Pro. Trace of the callbacks follows.

[ Upstream commit c2f8fd7949603efb03908e05abbf7726748c8de3 ] syzkaller reported null-ptr-deref [0] related to AF_NETROM. This is another self-accept issue from the strace log. [1] syz-executor creates an AF_NETROM socket and calls connect(), which is blocked at that time. Then, sk->sk_state is TCP_SYN_SENT and sock->state is SS_CONNECTING. [pid 5059] socket(AF_NETROM, SOCK_SEQPACKET, 0) = 4 [pid 5059] connect(4, {sa_family=AF_NETROM, sa_data="..." Another thread calls connect() concurrently, which finally fails with -EINVAL. However, the problem here is the socket state is reset even while the first connect() is blocked. [pid 5060] connect(4, NULL, 0 [pid 5060] <... connect resumed>) = -1 EINVAL (Invalid argument) As sk->state is TCP_CLOSE and sock->state is SS_UNCONNECTED, the following listen() succeeds. Then, the first connect() looks up itself as a listener and puts skb into the queue with skb->sk itself. As a result, the next accept() gets another FD of itself as 3, and the first connect() finishes. [pid 5060] listen(4, 0 [pid 5060] <... listen resumed>) = 0 [pid 5060] accept(4, NULL, NULL [pid 5060] <... accept resumed>) = 3 [pid 5059] <... connect resumed>) = 0 Then, accept4() is called but blocked, which causes the general protection fault later. [pid 5059] accept4(4, NULL, 0x20000400, SOCK_NONBLOCK After that, another self-accept occurs by accept() and writev(). [pid 5060] accept(4, NULL, NULL [pid 5061] writev(3, [{iov_base=...}] [pid 5061] <... writev resumed>) = 99 [pid 5060] <... accept resumed>) = 6 Finally, the leader thread close()s all FDs. Since the three FDs reference the same socket, nr_release() does the cleanup for it three times, and the remaining accept4() causes the following fault. [pid 5058] close(3) = 0 [pid 5058] close(4) = 0 [pid 5058] close(5) = -1 EBADF (Bad file descriptor) [pid 5058] close(6) = 0 [pid 5058] <... exit_group resumed>) = ?

If there are multiple PFC priorities enabled at a time and for all such flows to backoff, each priority will have to assert backpressure at different TL3/TL2 scheduler nodes and these flows will need to submit egress pkts to these nodes. Current PFC configuration has an issue where in only one backpressure scheduler node is being allocated which is resulting in only one PFC priority to work. This patch fixes this issue.

When issuing a sync via ice_ptp_exec_tmr_cmd(), the hardware will simultaneously apply the commands programmed for the main timer and each PHY port. Neither the main timer command register, nor the PHY port command registers auto clear on command execution. During the execution of a timer command intended for a single port on E822 devices, such as those used to configure a PHY during link up, the driver is not correctly clearing the previous commands. This results in unintentionally executing the last programmed command on the main timer and other PHY ports whenever performing reconfiguration on E822 ports after link up. This results in unintended side effects on other timers, depending on what command was previously programmed. To fix this, the driver must ensure that the main timer and all other PHY ports are properly initialized to perform no action. The enumeration for timer commands does not include an enumeration value for doing nothing. Introduce ICE_PTP_NOP for this purpose. When writing a timer command to hardware, leave the command bits set to zero which indicates that no operation should be performed on that port. Modify ice_ptp_one_port_cmd() to always initialize all ports. For all ports other than the one being configured, write their timer command register to ICE_PTP_NOP. This ensures that no side effect happens on the timer command. To fix this for the PHY ports, modify ice_ptp_one_port_cmd() to always initialize all other ports to ICE_PTP_NOP. This ensures that no side effects happen on the other ports. Call ice_ptp_src_cmd() with a command value if ICE_PTP_NOP in ice_sync_phy_timer_e822() and ice_start_phy_timer_e822(). With both of these changes, the driver should no longer execute a stale command on the main timer or another PHY port when reconfiguring one of the PHY ports after link up.

This commit makes it so that even if the BIG sync established event arrives with error status, a new hconn is added for each BIS, and the iso layer is notified about the failed connections. Unsuccesful bis connections will be marked using the HCI_CONN_BIG_SYNC_FAILED flag. From the iso layer, the POLLERR event is triggered on the newly allocated bis sockets, before adding them to the accept list of the parent socket. From user space, a new fd for each failed bis connection will be obtained by calling accept. The user should check for the POLLERR event on the new socket, to determine if the connection was successful or not. The HCI_CONN_BIG_SYNC flag has been added to mark whether the BIG sync has been successfully established.

This might possibly be done for treating bpf_rbtree_remove and others as KF_RELEASE and then later check correct reg->off in helper argument checks. But this is not the case, those helpers are already not KF_RELEASE and permit non-zero reg->off and verify it later to match the subobject in BTF type. However, this logic leads to bpf_obj_drop permitting free of register arguments with non-zero offset when they point to a graph root or node within them, which is not ok. For instance: struct foo { int i; int j; struct bpf_rb_node node; }; struct foo *f = bpf_obj_new(typeof(*f)); if (!f) ... bpf_obj_drop(f); // OK bpf_obj_drop(&f->i); // still ok from verifier PoV bpf_obj_drop(&f->node); // Not OK, but permitted right now Fix this by dropping the whole part of code altogether.

Apparently, the intention is that status_driver_data[] is used for driver specific data, and fills up the size of the union to 40 bytes, just like the other ones. This is indeed what actually happens, but only because of the combination of two mistakes: - "void *status_driver_data[18 / sizeof(void *)];" is intended to be 18 bytes long but is actually two bytes shorter because of rounding-down in the division, to a multiple of the pointer size (4 bytes or 8 bytes). - The other fields combined are intended to be 22 bytes long, but are actually 24 bytes because of padding in front of the unaligned tx_time member, and in front of the pointer array. The two mistakes cancel out. so the size ends up fine, but it seems more helpful to make this explicit, by having a multiple of 8 bytes in the size calculation and explicitly describing the padding.

Previously, the kprobe entry used for this purpose was quite unstable and inherently broke relevant probes [1]. Now that a stable tracepoint is available, this commit replaces the bio latency check with it. One of the changes made during this replacement is the key used for the hash table.

The most critical issue with vm.memfd_noexec=2 (the fact that passing MFD_EXEC would bypass it entirely[1]) has been fixed in Andrew's tree[2], but there are still some outstanding issues that need to be addressed: * vm.memfd_noexec=2 shouldn't reject old-style memfd_create(2) syscalls because it will make it far to difficult to ever migrate. Instead it should imply MFD_EXEC. * The dmesg warnings are pr_warn_once(), which on most systems means that they will be used up by systemd or some other boot process and userspace developers will never see it. - For the !(flags & (MFD_EXEC | MFD_NOEXEC_SEAL)) case, outputting a rate-limited message to the kernel log is necessary to tell userspace that they should add the new flags. Arguably the most ideal way to deal with the spam concern[3,4] while still prompting userspace to switch to the new flags would be to only log the warning once per task or something similar. However, adding something to task_struct for tracking this would be needless bloat for a single pr_warn_ratelimited(). So just switch to pr_info_ratelimited() to avoid spamming the log with something that isn't a real warning. There's lots of info-level stuff in dmesg, it seems really unlikely that this should be an actual problem. Most programs are already switching to the new flags anyway. - For the vm.memfd_noexec=2 case, we need to log a warning for every failure because otherwise userspace will have no idea why their previously working program started returning -EACCES (previously -EINVAL) from memfd_create(2). pr_warn_once() is simply wrong here. * The racheting mechanism for vm.memfd_noexec makes it incredibly unappealing for most users to enable the sysctl because enabling it on &init_pid_ns means you need a system reboot to unset it. Given the actual security threat being protected against, CAP_SYS_ADMIN users being restricted in this way makes little sense. The argument for this ratcheting by the original author was that it allows you to have a hierarchical setting that cannot be unset by child pidnses, but this is not accurate -- changing the parent pidns's vm.memfd_noexec setting to be more restrictive didn't affect children. Instead, switch the vm.memfd_noexec sysctl to be properly hierarchical and allow CAP_SYS_ADMIN users (in the pidns's owning userns) to lower the setting as long as it is not lower than the parent's effective setting. This change also makes it so that changing a parent pidns's vm.memfd_noexec will affect all descendants, providing a properly hierarchical setting. The performance impact of this is incredibly minimal since the maximum depth of pidns is 32 and it is only checked during memfd_create(2) and unshare(CLONE_NEWPID). * The memfd selftests would not exit with a non-zero error code when certain tests that ran in a forked process (specifically the ones related to MFD_EXEC and MFD_NOEXEC_SEAL) failed.

This could be error-prone for future xmit hook ops. One of the possible errors is to return statuses of dst_output directly. To make the code safer, redefine LWTUNNEL_XMIT_CONTINUE value to distinguish from dst_output statuses and check the continue condition explicitly.

At the xmit hook, such return values would be treated implicitly as LWTUNNEL_XMIT_CONTINUE in ip(6)_finish_output2. When this happens, skbs that have been freed would continue to the neighbor subsystem, causing use-after-free bug and kernel crashes. To fix the incorrect behavior, skb_do_redirect return values can be simply discarded, the same as tc-egress behavior. On the other hand, bpf_lwt_xmit_reroute returns useful errors to local senders, e.g. PMTU information. Thus convert its return values to avoid the conflict with LWTUNNEL_XMIT_CONTINUE.

When in legacy mode (cgroupv1), the socket memory is charged into ->tcpmem which is independent of ->memory, so socket_pressure has nothing to do with socket's pressure at all. Things could be worse by taking socket_pressure into consideration in legacy mode, as a pressure in ->memory can lead to premature reclamation/throttling in socket. While for the default mode (cgroupv2), the socket memory is charged into ->memory, and ->tcpmem/->tcpmem_pressure are simply not used. So {socket,tcpmem}_pressure are only used in default/legacy mode respectively for indicating socket memory pressure. This patch fixes the pieces of code that make mixed use of both.

This is not right all the time. The retransmits will become zero-window probes in tcp_retransmit_timer() if the 'snd_wnd==0'. Therefore, the icsk->icsk_rto will come up to TCP_RTO_MAX sooner or later. However, the timer can be delayed and be triggered after 122877ms, not TCP_RTO_MAX, as I tested. Therefore, 'tcp_jiffies32 - tp->rcv_tstamp > TCP_RTO_MAX' is always true once the RTO come up to TCP_RTO_MAX, and the socket will die. Fix this by replacing the 'tcp_jiffies32' with '(u32)icsk->icsk_timeout', which is exact the timestamp of the timeout. However, "tp->rcv_tstamp" can restart from idle, then tp->rcv_tstamp could already be a long time (minutes or hours) in the past even on the first RTO. So we double check the timeout with the duration of the retransmission. Meanwhile, making "2 * TCP_RTO_MAX" as the timeout to avoid the socket dying too soon.

Similar to the flow implemented for unicast, DEFER_SETUP will also be used to bind multiple BISes for the same BIG, before starting Periodic Advertising and creating the BIG. The user will have to open a new socket for each BIS. By setting the BT_DEFER_SETUP socket option and calling connect, a new connection will be added for the BIG and advertising handle set by the socket QoS parameters. Since all BISes will be bound for the same BIG and advertising handle, the socket QoS options and base parameters should match for all connections. By calling connect on a socket that does not have the BT_DEFER_SETUP option set, periodic advertising will be started and the BIG will be created, with a BIS for each previously bound connection. Since a BIG cannot be reconfigured with additional BISes after creation, no more connections can be bound for the BIG after the start periodic advertising and create BIG commands have been queued. The bis_cleanup function has also been updated, so that the advertising set and the BIG will not be terminated unless there are no more bound or connected BISes. The HCI_CONN_BIG_CREATED connection flag has been added to indicate that the BIG has been successfully created. This flag is checked at bis_cleanup, so that the BIG is only terminated if the HCI_LE_Create_BIG_Complete has been received. This implementation has been tested on hardware, using the "isotest" tool with an additional command line option, to specify the number of BISes to create as part of the desired BIG: tools/isotest -i hci0 -s 00:00:00:00:00:00 -N 2 -G 1 -T 1 The btmon log shows that a BIG containing 2 BISes has been created: < HCI Command: LE Create Broadcast Isochronous Group (0x08|0x0068) plen 31 Handle: 0x01 Advertising Handle: 0x01 Number of BIS: 2 SDU Interval: 10000 us (0x002710) Maximum SDU size: 40 Maximum Latency: 10 ms (0x000a) RTN: 0x02 PHY: LE 2M (0x02) Packing: Sequential (0x00) Framing: Unframed (0x00) Encryption: 0x00 Broadcast Code: 00000000000000000000000000000000 > HCI Event: Command Status (0x0f) plen 4 LE Create Broadcast Isochronous Group (0x08|0x0068) ncmd 1 Status: Success (0x00) > HCI Event: LE Meta Event (0x3e) plen 23 LE Broadcast Isochronous Group Complete (0x1b) Status: Success (0x00) Handle: 0x01 BIG Synchronization Delay: 1974 us (0x0007b6) Transport Latency: 1974 us (0x0007b6) PHY: LE 2M (0x02) NSE: 3 BN: 1 PTO: 1 IRC: 3 Maximum PDU: 40 ISO Interval: 10.00 msec (0x0008) Connection Handle #0: 10 Connection Handle #1: 11 < HCI Command: LE Setup Isochronous Data Path (0x08|0x006e) plen 13 Handle: 10 Data Path Direction: Input (Host to Controller) (0x00) Data Path: HCI (0x00) Coding Format: Transparent (0x03) Company Codec ID: Ericsson Technology Licensing (0) Vendor Codec ID: 0 Controller Delay: 0 us (0x000000) Codec Configuration Length: 0 Codec Configuration: > HCI Event: Command Complete (0x0e) plen 6 LE Setup Isochronous Data Path (0x08|0x006e) ncmd 1 Status: Success (0x00) Handle: 10 < HCI Command: LE Setup Isochronous Data Path (0x08|0x006e) plen 13 Handle: 11 Data Path Direction: Input (Host to Controller) (0x00) Data Path: HCI (0x00) Coding Format: Transparent (0x03) Company Codec ID: Ericsson Technology Licensing (0) Vendor Codec ID: 0 Controller Delay: 0 us (0x000000) Codec Configuration Length: 0 Codec Configuration: > HCI Event: Command Complete (0x0e) plen 6 LE Setup Isochronous Data Path (0x08|0x006e) ncmd 1 Status: Success (0x00) Handle: 11 < ISO Data TX: Handle 10 flags 0x02 dlen 44 < ISO Data TX: Handle 11 flags 0x02 dlen 44 > HCI Event: Number of Completed Packets (0x13) plen 5 Num handles: 1 Handle: 10 Count: 1 > HCI Event: Number of Completed Packets (0x13) plen 5 Num handles: 1 Handle: 11 Count: 1 Signed-off-by: Iulia Tanasescu Signed-off-by: Luiz Augusto von Dentz Stable-dep-of: 7f74563e6140 ("Bluetooth: ISO: do not emit new LE Create CIS if previous is pending") Signed-off-by: Sasha Levin commit 3e740c8876d0066e915f01759c52b39fe7b837bb Author: Luiz Augusto von Dentz Date: Tue Jun 20 15:41:11 2023 -0700 Bluetooth: hci_event: Fix parsing of CIS Established Event [ Upstream commit 2be22f1941d5f661aa8043261d1bae5b6696c749 ] The ISO Interval on CIS Established Event uses 1.25 ms slots: BLUETOOTH CORE SPECIFICATION Version 5.3 | Vol 4, Part E page 2304: Time = N * 1.25 ms In addition to that this always update the QoS settings based on CIS Established Event.

However, the invocation itself may fail if, for instance, `bindgen` cannot locate `libclang`. This is fine for Kconfig (since the script will still fail and therefore disable Rust as it should), but it is pretty confusing for users of the `rustavailable` target given the error will be unrelated: ./scripts/rust_is_available.sh: 21: arithmetic expression: expecting primary: "100000 * + 100 * + " make: *** [Makefile:1816: rustavailable] Error 2 Instead, run the `bindgen` invocation independently in a previous step, saving its output and return code. If it fails, then show the user a proper error message. Otherwise, continue as usual with the saved output. Since the previous patch we show a reference to the docs, and the docs now explain how `bindgen` looks for `libclang`, thus the error message can leverage the documentation, avoiding duplication here (and making users aware of the setup guide in the documentation).

The function therefore needs to make sure that sk lives long enough to be consumed from __inet_lookup_skb. The path through the stack for a TCPv4 packet is roughly: netif_receive_skb_core: takes RCU read lock __netif_receive_skb_core: sch_handle_ingress: tcf_classify: bpf_sk_assign() deliver_ptype_list_skb: deliver_skb: ip_packet_type->func == ip_rcv: ip_rcv_core: ip_rcv_finish_core: dst_input: ip_local_deliver: ip_local_deliver_finish: ip_protocol_deliver_rcu: tcp_v4_rcv: __inet_lookup_skb: skb_steal_sock The existing helper takes advantage of the fact that everything happens in the same RCU critical section: for sockets with SOCK_RCU_FREE set bpf_sk_assign never takes a reference. skb_steal_sock then checks SOCK_RCU_FREE again and does sock_put if necessary. This approach assumes that SOCK_RCU_FREE is never set on a sk between bpf_sk_assign and skb_steal_sock, but this invariant is violated by unhashed UDP sockets. A new UDP socket is created in TCP_CLOSE state but without SOCK_RCU_FREE set. That flag is only added in udp_lib_get_port() which happens when a socket is bound. When bpf_sk_assign was added it wasn't possible to access unhashed UDP sockets from BPF, so this wasn't a problem. This changed in commit 0c48eefae712 ("sock_map: Lift socket state restriction for datagram sockets"), but the helper wasn't adjusted accordingly. The following sequence of events will therefore lead to a refcount leak: 1. Add socket(AF_INET, SOCK_DGRAM) to a sockmap. 2. Pull socket out of sockmap and bpf_sk_assign it. Since SOCK_RCU_FREE is not set we increment the refcount. 3. bind() or connect() the socket, setting SOCK_RCU_FREE. 4. skb_steal_sock will now set refcounted = false due to SOCK_RCU_FREE. 5. tcp_v4_rcv() skips sock_put(). Fix the problem by rejecting unhashed sockets in bpf_sk_assign(). This matches the behaviour of __inet_lookup_skb which is ultimately the goal of bpf_sk_assign().

To support these properly we remember whether a group has a connected socket and skip the fast reuseport early-return. In effect we continue scoring all reuseport sockets and then choose the one with the highest score. The current code fails to re-calculate the score for the result of lookup_reuseport. According to Kuniyuki Iwashima: 1) SO_INCOMING_CPU is set -> selected sk might have +1 score 2) BPF prog returns ESTABLISHED and/or SO_INCOMING_CPU sk -> selected sk will have more than 8 Using the old score could trigger more lookups depending on the order that sockets are created. sk -> sk (SO_INCOMING_CPU) -> sk (ESTABLISHED) | | `-> select the next SO_INCOMING_CPU sk | `-> select itself (We should save this lookup) Fixes: efc6b6f6c311 ("udp: Improve load balancing for SO_REUSEPORT.")

Instead scan through the list of defaults for blocks of adjacent registers and do a single allocation and insert for each such block. No functional change. We do not take advantage of the maple tree preallocation, this is purely at the regcache level.

This happens after the driver's remove function is called. However, nomadik's clock is disabled in the remove function. There's a short timeframe where nomadik is still registered with the hwrng core although its clock is disabled. I suppose the clock must be active to access the hardware and serve requests from the hwrng core. Switch to devm_clk_get_enabled and let devres disable the clock and unregister the hwrng.

There are two situations where this is wrong. First, if the program type didn't actually change. In that case original SEC handler should work just fine. Second, catch-all custom SEC handler is supposed to work with any BPF program type and SEC() annotation, so it also doesn't make sense to reset that. This patch fixes both issues. This was reported recently in the context of breaking perf tool, which uses custom catch-all handler for fancy BPF prologue generation logic. This patch should fix the issue.

All pkeys have an internal header/payload structure, which is opaque to the userspace. The header structures for PKEY_TYPE_EP11 and PKEY_TYPE_EP11_AES are nearly identical and there is no reason, why different structures are used. In preparation to fix the keyversion handling in the broken PKEY IOCTLs, the same header structure is used for PKEY_TYPE_EP11 and PKEY_TYPE_EP11_AES.

The problem it found is the intial sysctl file value which was computed as: static int sysctl_sched_rr_timeslice = (MSEC_PER_SEC / HZ) * RR_TIMESLICE; which works fine as long as MSEC_PER_SEC is multiple of HZ, however it introduces 10% rounding error for CONFIG_HZ_300: (MSEC_PER_SEC / HZ) * (100 * HZ / 1000) (1000 / 300) * (100 * 300 / 1000) 3 * 30 = 90 This can be easily fixed by reversing the order of the multiplication and division.

Since these are configuration registers rather than identification registers the assumptions the cpufeature code makes about how unknown bitfields behave are invalid, leading to warnings when SME features like FA64 are enabled and we hotplug a CPU: CPU features: SANITY CHECK: Unexpected variation in SYS_SMCR_EL1. Boot CPU: 0x0000000000000f, CPU3: 0x0000008000000f CPU features: Unsupported CPU feature variation detected. SVE has no controls other than the vector length so is not yet impacted but the same issue will apply there if any are defined. Since the only field we are interested in having the cpufeature code handle is the length field and we use a custom read function to obtain the value we can avoid these warnings by filtering out all other bits when we return the register value, if we're doing that we don't need to bother reading the register at all and can simply use the RDVL/RDSVL value we were filling in instead.

This is done by choosing an idle state shallower than the previously selected one. However, when doing this, the idle duration estimate needs to be adjusted so as to prevent the scheduler tick from being stopped when the candidate idle state is shallow, which may lead to excessive energy usage if the CPU is not woken up quickly enough going forward. Moreover, if the scheduler tick has been stopped already and the new idle duration estimate is too small, the replacement candidate state cannot be used. Modify the relevant code to take the above observations into account.

Available SCMI powercap zones are retrieved dynamically from the platform at probe time and, while any defined hierarchy between the zones is described properly in the zones descriptor, the platform returns the availables zones with no particular well-defined order: as a consequence, the trees possibly composing the hierarchy of zones have to be somehow walked properly to register the retrieved zones from the root. Currently the ARM SCMI Powercap driver walks the zones using a recursive algorithm; this approach, even though correct and tested can lead to kernel stack overflow when processing a returned hierarchy of zones composed by particularly high trees. Avoid possible kernel stack overflow by substituting the recursive approach with an iterative one supported by a dynamically allocated stack-like data structure.

That means that resolving the uid/gid via current_user_ns() can save a kuid that isn't mapped in the associated namespace when the filesystem is finally mounted. This means that it is possible for an unprivileged user to create files owned by any group in a tmpfs mount (since we can set the SUID bit on the tmpfs directory), or a tmpfs that is owned by any user, including the root group/user." The contract for {g,u}id mount options and {g,u}id values in general set from userspace has always been that they are translated according to the caller's idmapping. In so far, tmpfs has been doing the correct thing. But since tmpfs is mountable in unprivileged contexts it is also necessary to verify that the resulting {k,g}uid is representable in the namespace of the superblock to avoid such bugs as above. The new mount api's cross-namespace delegation abilities are already widely used. After having talked to a bunch of userspace this is the most faithful solution with minimal regression risks. I know of one users - systemd - that makes use of the new mount api in this way and they don't set unresolable {g,u}ids. So the regression risk is minimal.

An underflow can happen with EFD_SEMAPHORE eventfds in at least the following three subsystems: (1) virt/kvm/eventfd.c (2) drivers/vfio/virqfd.c (3) drivers/virt/acrn/irqfd.c where (2) and (3) are just modeled after (1). An eventfd must be specified for use with the KVM_IRQFD ioctl(). This can also be an EFD_SEMAPHORE eventfd. When the eventfd count is zero or has been decremented to zero an underflow can be triggered when the irqfd is shut down by raising the KVM_IRQFD_FLAG_DEASSIGN flag in the KVM_IRQFD ioctl(): // ctx->count == 0 kvm_vm_ioctl() -> kvm_irqfd() -> kvm_irqfd_deassign() -> irqfd_deactivate() -> irqfd_shutdown() -> eventfd_ctx_remove_wait_queue(&cnt) -> eventfd_ctx_do_read(&cnt) Userspace polling on the eventfd wouldn't notice the underflow because 1 is always returned as the value from eventfd_read() while ctx->count would've underflowed. It's not a huge deal because this should only be happening when the irqfd is shutdown but we should still fix it and avoid the spurious wakeup.

It was trying to work around an issue at the crypto layer by excluding ASYNC implementations of gcm(aes), because a bug in the AESNI version caused reordering when some requests bypassed the cryptd queue while older requests were still pending on the queue. This was fixed by commit 38b2f68b4264 ("crypto: aesni - Fix cryptd reordering problem on gcm"), which pre-dates ab046a5d4be4. Herbert Xu confirmed that all ASYNC implementations are expected to maintain the ordering of completions wrt requests, so we can use them in MACsec. On my test machine, this restores the performance of a single netperf instance, from 1.4Gbps to 4.4Gbps.

After commit 4fb8e46c1bc4 ("PCI: tegra194: Enable support for 256 Byte payload"), we initialize MPS=256 for tegra194 Root Ports before enumerating the hierarchy. Consider an Endpoint that supports only MPS=128. In the default situation (CONFIG_PCIE_BUS_DEFAULT set and no "pci=pcie_bus_*" parameter), Linux tries to configure the MPS of every device to match the upstream bridge. If the Endpoint is directly below the Root Port, Linux can reduce the Root Port MPS to 128 to match the Endpoint. But if there's a switch in the middle, Linux doesn't reduce the Root Port MPS because other devices below the switch may already be configured with MPS larger than 128. This scenario results in uncorrectable Malformed TLP errors if the Root Port sends TLPs with payloads larger than 128 bytes. These errors can be avoided by using the "pci=pcie_bus_safe" parameter, but it doesn't seem to be a good idea to always have this parameter even for basic functionality to work. Revert commit 4fb8e46c1bc4 ("PCI: tegra194: Enable support for 256 Byte payload") so the Root Ports default to MPS=128, which all devices support. If peer-to-peer DMA is not required, one can use "pci=pcie_bus_perf" to get the benefit of larger MPS settings.

BPF programs that run on connect can rewrite the connect address. For the connect system call this isn't a problem, because a copy of the address is made when it is moved into kernel space. However, kernel_connect simply passes through the address it is given, so the caller may observe its address value unexpectedly change. A practical example where this is problematic is where NFS is combined with a system such as Cilium which implements BPF-based load balancing. A common pattern in software-defined storage systems is to have an NFS mount that connects to a persistent virtual IP which in turn maps to an ephemeral server IP. This is usually done to achieve high availability: if your server goes down you can quickly spin up a replacement and remap the virtual IP to that endpoint. With BPF-based load balancing, mounts will forget the virtual IP address when the address rewrite occurs because a pointer to the only copy of that address is passed down the stack. Server failover then breaks, because clients have forgotten the virtual IP address. Reconnects fail and mounts remain broken. This patch was tested by setting up a scenario like this and ensuring that NFS reconnects worked after applying the patch. Signed-off-by: Jordan Rife Signed-off-by: David S.

Add a "never" option to the nx_huge_pages module param to allow userspace to do a one-way hard disabling of the mitigation, and don't create the per-VM recovery threads when the mitigation is hard disabled. Letting userspace pinky swear that userspace doesn't want to enable NX mitigation (without reloading KVM) allows certain use cases to avoid the latency problems associated with spawning a kthread for each VM. E.g. in FaaS use cases, the guest kernel is trusted and the host may create 100+ VMs per logical CPU, which can result in 100ms+ latencies when a burst of VMs is created.

This makes the TPM fail probe on Lenovo Legion Y540 laptop. Since only Microsoft Pluton is the only known combination of AMD CPU and fTPM from other vendor, disable hwrng otherwise. In order to make sysadmin aware of this, print also info message to the klog.

The intel_pstate CPU frequency scaling driver does not use policy->cur and it is 0. When the CPU frequency is outdated arch_freq_get_on_cpu() will default to the nominal clock frequency when its call to cpufreq_quick_getpolicy_cur returns the never updated 0. Thus, the listed frequency might be outside of currently set limits. Some users are complaining about the high reported frequency, albeit stale, when their system is idle and/or it is above the reduced maximum they have set. This patch will maintain policy_cur for the intel_pstate driver at the current minimum CPU frequency.

Current code supposes that it is enough to provide forward progress by just waking up one wait queue after one completion batch is done. Unfortunately this way isn't enough, cause waiter can be added to wait queue just after it is woken up. Follows one example(64 depth, wake_batch is 8) 1) all 64 tags are active 2) in each wait queue, there is only one single waiter 3) each time one completion batch(8 completions) wakes up just one waiter in each wait queue, then immediately one new sleeper is added to this wait queue 4) after 64 completions, 8 waiters are wakeup, and there are still 8 waiters in each wait queue 5) after another 8 active tags are completed, only one waiter can be wakeup, and the other 7 can't be waken up anymore. Turns out it isn't easy to fix this problem, so simply wakeup enough waiters for single batch.

As suggested by Steven: > I believe we should add a ref count to trace_pipe and the per_cpu > trace_pipes, where if they are opened, nothing else can read it. > > Opening trace_pipe locks all per_cpu ref counts, if any of them are > open, then the trace_pipe open will fail (and releases any ref counts > it had taken). > > Opening a per_cpu trace_pipe will up the ref count for just that > CPU buffer.

But because we only need to know whether per_cpu trace_pipe is open or not, using a cpumask instead of using ref count may be easier. After this patch, users will find that: - Main trace_pipe can be opened by only one user, and if it is opened, all per_cpu trace_pipes cannot be opened; - Per_cpu trace_pipes can be opened by multiple users, but each per_cpu trace_pipe can only be opened by one user. And if one of them is opened, main trace_pipe cannot be opened.

Since the specification makes no statement about transmitter range, and as the specific sfp module that had been tested features only 2m fiber - short-range (SR) modes are selected. The 100G speed is irrelevant because it would require multiple fibers / multiple SFP28 modules combined under one netdev. sfp-bus.c only handles a single module per netdev, so only 25Gbps modes are selected. sfp_parse_support already handles SFF8024_ECC_100GBASE_SR4_25GBASE_SR with compatible properties, however that entry is a contradiction in itself since with SFP(28) 100GBASE_SR4 is impossible - that would likely be a mode for qsfp modules only. Add a case for SFF8024_ECC_100G_25GAUI_C2M_AOC selecting 25gbase-r interface mode and 25000baseSR link mode. Also enforce SFP28 bitrate limits on the values read from sfp eeprom as requested by Russell King. Tested with fs.com S28-AO02 AOC SFP28 module.

Instead, we rely on offline_pages() to also perform actual page migration, which might fail or take a very long time. In that case, it's possible to easily run into endless loops that cannot be aborted anymore (as offlining is triggered by a workqueue then): For example, a single (accidentally) permanently unmovable page in ZONE_MOVABLE results in an endless loop. For ZONE_NORMAL, races between isolating the pageblock (and checking for unmovable pages) and concurrent page allocation are possible and similarly result in endless loops. The idea of the unsafe unplug mode was to make it possible to more reliably unplug large memory blocks. However, (a) we really should be tackling that differently, by extending the alloc_contig_range()-based mechanism; and (b) this mode is not the default and as far as I know, it's unused either way. So let's simply get rid of it. Signed-off-by: David Hildenbrand Message-Id: <20230713145551.2824980-2-david@redhat.com> Signed-off-by: Michael S.

Some drivers/layers like dm-crypt and the directi IO code will test for it and just fail. Other drivers like SCSI just assume the requirement is met and will end up in infinte retry loops. The problem for drivers like SCSI is that it uses functions like blk_rq_cur_sectors and blk_rq_sectors which divide the request's length by 512. If there's lefovers then it just gets dropped. But other code in the block/scsi layer may use blk_rq_bytes/blk_rq_cur_bytes and end up thinking there is still data left and try to retry the cmd. We can then end up getting stuck in retry loops where part of the block/scsi thinks there is data left, but other parts think we want to do IOs of zero length. Linux will always check for alignment, but windows will not. When vhost-scsi then translates the iovec it gets from a windows guest to a scatterlist, we can end up with sg items where the sg->length is not divisible by 512 due to the misaligned offset: sg[0].offset = 255; sg[0].length = 3841; sg... sg[N].offset = 0; sg[N].length = 255; When the lio backends then convert the SG to bios or other iovecs, we end up sending them with the same misaligned values and can hit the issues above. This just has us drop down to allocating a temp page and copying the data when we detect a misaligned buffer and the IO is large enough that it will get split into multiple bad IOs.

It has to align the TLV sections by 4 bytes. But the code was using an u8 to store the newly calculated length of this section (with alignment). And the new calculated length was then used to allocate the skbuff. But the actual code to copy in the data is using the extraie.len and not the calculated "aligned" length. The length of extraie with IEEE80211_HW_SINGLE_SCAN_ON_ALL_BANDS enabled was 264 bytes during tests with a wifi card. But it only allocated 8 bytes (264 bytes % 256) for it. As consequence, the code to memcpy the extraie into the skb was then just overwriting data after skb->end. Things like shinfo were therefore corrupted. This could usually be seen by a crash in skb_zcopy_clear which tried to call a ubuf_info callback (using a bogus address).

Sometimes, it chooses to run two different VMs at different levels but they share some of their address space. In such setups VTL2 (higher level VM) has visibility of all of the VTL0 (level 0) memory space. When the CONFIG_X86_MPPARSE is enabled for VTL2, the VTL2 kernel performs a search within the low memory to locate MP tables. However, in systems where VTL0 manages the low memory and may contain valid tables, this scanning can result in incorrect MP table information being provided to the VTL2 kernel, mistakenly considering VTL0's MP table as its own Add noop functions to avoid MP parse scan by VTL2.

The warning was introduced by the new field-spanning write checks which were enabled recently. Fix this by replacing the channel_list[1] declaration at the end of the struct with a flexible array declaration. Most users of struct brcmf_scan_params_le calculate the size to alloc using the size of the non flex-array part of the struct + needed extra space, so they do not care about sizeof(struct brcmf_scan_params_le). brcmf_notify_escan_complete() however uses the struct on the stack, expecting there to be room for at least 1 entry in the channel-list to store the special -1 abort channel-id. To make this work use an anonymous union with a padding member added + the actual channel_list flexible array.

We have originally guarded fiddling with CHECKFLAGS in our arch Makefile by checking for the CONFIG_LOONGARCH variable, not set for targets such as `distclean', etc. that neither include `.config' nor use the compiler. Starting from commit 805b2e1d427aab4 ("kbuild: include Makefile.compiler only when compiler is needed") we have had a generic `need-compiler' variable explicitly telling us if the compiler will be used and thus its capabilities need to be checked and expressed in the form of compilation flags. If this variable is not set, then `make' functions such as `cc-option' are undefined, causing all kinds of weirdness to happen if we expect specific results to be returned. It doesn't cause problems on LoongArch now. But as a guard we replace the check for CONFIG_LOONGARCH with one for `need-compiler' instead, so as to prevent the compiler from being ever called for CHECKFLAGS when not needed.

The descriptor reports wrong dB ranges for playback, and the capture volume/switch don't influence on the actual recording at all. Moreover, there seem instabilities in the connection, and at best, we should disable the runtime PM. So this ended up with a quirk entry for: - Correct the playback dB range; I picked up some reasonable values but it's a guess work - Disable the capture mixer; it's completely useless and confuses PA/PW - Suppress get-sample-rate, apply the delay for message handling, and suppress the auto-suspend The behavior of the wheel control on the headset is somehow flaky, too, but it's an issue of HID.

This function is used in various cases when basic settings for the device have to be changed like High Performance Ficon related parameters or copy pair settings. The functions iterates over the device->ccw_queue and also removes the requests from the block->ccw_queue. In case the device is started on an alias device instead of the base device it might be removed from the block->ccw_queue without having it canceled properly before. This might lead to a hanging device since the request is no longer on a queue and can not be handled properly. Fix by iterating over the block->ccw_queue instead of the device->ccw_queue. This will take care of all blocklayer related requests and handle them on all associated DASD devices.

However, with this patch the above failure is still reproducible. So this patch does not fix any real observed issue so far, but at least is useful for confirming that the above issue is not caused by a pending IRQ but rather looks like a DA7219 hardware issue with an IRQ unexpectedly generated after jack detection is already disabled.
