Calculate max_hw_heartbeat_ms based on input clock frequency. 2. Update frequency check to require a minimum frequency of 1Mhz. 3. Limit the close and open window percent to hardware supported value to avoid truncation. 4. If the user input timeout exceeds the maximum timeout supported, use only open window and the framework supports the higher timeouts.

If anyone has any objections, please let me know. ------------------ From: Alexander Kozhinov <ak.alexander.kozhinov@gmail.com> [ Upstream commit 889b2ae9139a87b3390f7003cb1bb3d65bf90a26 ] There is an approach made to implement gs_usb firmware/driver based on Zephyr RTOS. It was found that USB stack of Zephyr RTOS overwrites USB EP addresses, if they have different last 4 bytes in absence of other endpoints. For example in case of gs_usb candlelight firmware EP-IN is 0x81 and EP-OUT 0x02. If there are no additional USB endpoints, Zephyr RTOS will overwrite EP-OUT to 0x01. More information can be found in the discussion with Zephyr RTOS USB stack maintainer here: https://github.com/zephyrproject-rtos/zephyr/issues/67812 There are already two different gs_usb FW driver implementations based on Zephyr RTOS: 1. https://github.com/CANnectivity/cannectivity (by: https://github.com/henrikbrixandersen) 2. https://github.com/zephyrproject-rtos/zephyr/compare/main...KozhinovAlexander:zephyr:gs_usb (by: https://github.com/KozhinovAlexander) At the moment both Zephyr RTOS implementations use dummy USB endpoint, to overcome described USB stack behavior from Zephyr itself. Since Zephyr RTOS is intended to be used on microcontrollers with very constrained amount of resources (ROM, RAM) and additional endpoint requires memory, it is more convenient to update the gs_usb driver in the Linux kernel. To fix this problem, update the gs_usb driver from using hard coded endpoint numbers to evaluate the endpoint descriptors and use the endpoints provided there.

If anyone has any objections, please let me know. ------------------ From: Jinghao Jia <jinghao7@illinois.edu> [ Upstream commit 146b6f1112eb30a19776d6c323c994e9d67790db ] Under certain kernel configurations when building with Clang/LLVM, the compiler does not generate a return or jump as the terminator instruction for ip_vs_protocol_init(), triggering the following objtool warning during build time: vmlinux.o: warning: objtool: ip_vs_protocol_init() falls through to next function __initstub__kmod_ip_vs_rr__935_123_ip_vs_rr_init6() At runtime, this either causes an oops when trying to load the ipvs module or a boot-time panic if ipvs is built-in. This same issue has been reported by the Intel kernel test robot previously. Digging deeper into both LLVM and the kernel code reveals this to be a undefined behavior problem. ip_vs_protocol_init() uses a on-stack buffer of 64 chars to store the registered protocol names and leaves it uninitialized after definition. The function calls strnlen() when concatenating protocol names into the buffer. With CONFIG_FORTIFY_SOURCE strnlen() performs an extra step to check whether the last byte of the input char buffer is a null character (commit 3009f891bb9f ("fortify: Allow strlen() and strnlen() to pass compile-time known lengths")). This, together with possibly other configurations, cause the following IR to be generated: define hidden i32 @ip_vs_protocol_init() local_unnamed_addr #5 section ".init.text" align 16 !kcfi_type !29 { %1 = alloca [64 x i8], align 16 ... 14: ; preds = %11 %15 = getelementptr inbounds i8, ptr %1, i64 63 %16 = load i8, ptr %15, align 1 %17 = tail call i1 @llvm.is.constant.i8(i8 %16) %18 = icmp eq i8 %16, 0 %19 = select i1 %17, i1 %18, i1 false br i1 %19, label %20, label %23 20: ; preds = %14 %21 = call i64 @strlen(ptr noundef nonnull dereferenceable(1) %1) #23 ... 23: ; preds = %14, %11, %20 %24 = call i64 @strnlen(ptr noundef nonnull dereferenceable(1) %1, i64 noundef 64) #24 ... } The above code calculates the address of the last char in the buffer (value %15) and then loads from it (value %16). Because the buffer is never initialized, the LLVM GVN pass marks value %16 as undefined: %13 = getelementptr inbounds i8, ptr %1, i64 63 br i1 undef, label %14, label %17 This gives later passes (SCCP, in particular) more DCE opportunities by propagating the undef value further, and eventually removes everything after the load on the uninitialized stack location: define hidden i32 @ip_vs_protocol_init() local_unnamed_addr #0 section ".init.text" align 16 !kcfi_type !11 { %1 = alloca [64 x i8], align 16 ... 12: ; preds = %11 %13 = getelementptr inbounds i8, ptr %1, i64 63 unreachable } In this way, the generated native code will just fall through to the next function, as LLVM does not generate any code for the unreachable IR instruction and leaves the function without a terminator. Zero the on-stack buffer to avoid this possible UB.

And enetc_setup_tc_mqprio() calls enetc_change_preemptible_tcs() to configure preemptible TCs. However, only PF is able to configure preemptible TCs. Because only PF has related registers, while VF does not have these registers. So for VF, its hw->port pointer is NULL. Therefore, VF will access an invalid pointer when accessing a non-existent register, which will cause a crash issue.

Whenever this function is used to enqueue SKBs, the backlog statistic of the tbf is not increased correctly. This can lead to underflows of the 'backlog' byte-statistic value when these packets are dequeued from tbf. Reproduce the bug: Ensure that the sender machine has GSO enabled. Configured the tbf on the outgoing interface of the machine as follows (burstsize = 1 MTU): $ tc qdisc add dev <oif> root handle 1: tbf rate 50Mbit burst 1514 latency 50ms Send bulk TCP traffic out via this interface, e.g., by running an iPerf3 client on this machine. Check the qdisc statistics: $ tc -s qdisc show dev <oif> The 'backlog' byte-statistic has incorrect values while traffic is transferred, e.g., high values due to u32 underflows. When the transfer is stopped, the value is != 0, which should never happen. This patch fixes this bug by updating the statistics correctly, even if single SKBs of a GSO SKB cannot be enqueued.

However everywhere else a normal thermal policy is stored inside this variable, potentially confusing the platform profile. Fix this by always storing normal thermal policy values inside throttle_thermal_policy_mode and only do the conversion when writing the thermal policy to hardware. This also fixes the order in which throttle_thermal_policy_switch_next() steps through the thermal modes on Vivobook machines.

Move increment later in the code and make decrement of sk_tskey in error path. This solution is still racy in case of multiple threads doing snedmsg() over the very same socket in parallel, but still makes error path much more predictable.

There are several conditions that must be fulfilled for the leak to occur: * an ICMPv6 packet indicating a change of the MTU for the path is received, resulting in an exception dst being created * a TCP connection that uses the exception dst for routing packets must start timing out so that TCP begins retransmissions * after the exception dst expires, the FIB6 garbage collector must not run before TCP executes ip6_negative_advice() for the expired exception dst When TCP executes ip6_negative_advice() for an exception dst that has expired and if no other socket holds a reference to the exception dst, the refcount of the exception dst is 2, which corresponds to the increment made by dst_init() and the increment made by the TCP socket for which the connection is timing out. The refcount made by the socket is never released. The refcount of the dst is decremented in sk_dst_reset() but that decrement is counteracted by a dst_hold() intentionally placed just before the sk_dst_reset() in ip6_negative_advice(). After ip6_negative_advice() has finished, there is no other object tied to the dst. The socket lost its reference stored in sk_dst_cache and the dst is no longer in the exception table. The exception dst becomes a leaked object. As a result of this dst leak, an unbalanced refcount is reported for the loopback device of a net namespace being destroyed under kernels that do not contain e5f80fcf869a ("ipv6: give an IPv6 dev to blackhole_netdev"): unregister_netdevice: waiting for lo to become free. Usage count = 2 Fix the dst leak by removing the dst_hold() in ip6_negative_advice(). The patch that introduced the dst_hold() in ip6_negative_advice() was 92f1655aa2b22 ("net: fix __dst_negative_advice() race"). But 92f1655aa2b22 merely refactored the code with regards to the dst refcount so the issue was present even before 92f1655aa2b22. The bug was introduced in 54c1a859efd9f ("ipv6: Don't drop cache route entry unless timer actually expired.") where the expired cached route is deleted and the sk_dst_cache member of the socket is set to NULL by calling dst_negative_advice() but the refcount belonging to the socket is left unbalanced. The IPv4 version - ipv4_negative_advice() - is not affected by this bug. When the TCP connection times out ipv4_negative_advice() merely resets the sk_dst_cache of the socket while decrementing the refcount of the exception dst. Fixes: 92f1655aa2b22 ("net: fix __dst_negative_advice() race") Fixes: 54c1a859efd9f ("ipv6: Don't drop cache route entry unless timer actually expired.")

This commit mistakenly enabled IPSEC offload for API v1.5. No implementation of the v1.5 API has support for IPSEC offload. This offload is only supported by the Linux PF as mailbox API v1.4. In fact, the v1.5 API is not implemented in any Linux PF. Attempting to enable IPSEC offload on a PF which supports v1.5 API will not work. Only the Linux upstream ixgbe and ixgbevf support IPSEC offload, and only as part of the v1.4 API. Fix the ixgbevf Linux driver to stop attempting IPSEC offload when the mailbox API does not support it. The existing API design choice makes it difficult to support future API versions, as other non-Linux hosts do not implement IPSEC offload. If we add support for v1.5 to the Linux PF, then we lose support for IPSEC offload. A full solution likely requires a new mailbox API with a proper negotiation to check that IPSEC is actually supported by the host.

The Linux PF only supports API v1.4, and does not currently have support for the v1.5 API. The logged message can confuse users, as the v1.5 API is valid, but just happens to not currently be supported by the Linux PF. Downgrade the info message to a debug message, and fix the language to use 'unsupported' instead of 'invalid' to improve message clarity.

Disable bh and perform three checks before restoring the percpu inner header offsets to validate that the percpu area is valid for this skbuff: 1) If the NFT_PKTINFO_INNER_FULL flag is set on, then this skbuff has already been parsed before for inner header fetching to register. 2) Validate that the percpu area refers to this skbuff using the skbuff pointer as a cookie. If there is a cookie mismatch, then this skbuff needs to be parsed again. 3) Finally, validate if the percpu area refers to this tunnel type. Only after these three checks the percpu area is restored to a on-stack copy and bh is enabled again. After inner header fetching, the on-stack copy is stored back to the percpu area.

However, in fl_set_erspan_opt() it initializes all bits of erspan_opt and its mask to 1. This inadvertently requires packets to match not only the (version, dir, hwid) fields but also the other fields that are unexpectedly set to 1. This patch resolves the issue by ensuring that only the (version, dir, hwid) fields are configured in fl_set_erspan_opt(), leaving the other fields to 0 in erspan_opt.

I considered that checking for errors when calling rhashtable_walk_next() was sufficient to detect the resizing. However, rhashtable_walk_next() returns -EAGAIN only at the end of the iteration, which is too late, because a gc work containing duplicated elements could have been already scheduled for removal to the worker. Add a u32 gc worker sequence number per set, bump it on every workqueue run. Annotate gc worker sequence number on the expired element. Use it to skip those already seen in this gc workqueue run. Note that this new field is never reset in case gc transaction fails, so next gc worker run on the expired element overrides it. Wraparound of gc worker sequence number should not be an issue with stale gc worker sequence number in the element, that would just postpone the element removal in one gc run. Note that it is not possible to use flags to annotate that element is pending gc run to detect duplicates, given that gc transaction can be invalidated in case of update from the control plane, therefore, not allowing to clear such flag.

If anyone has any objections, please let me know. ------------------ From: Kory Maincent <kory.maincent@bootlin.com> [ Upstream commit 910c4788d6155b2202ec88273376cd7ecdc24f0a ] A bitset without mask in a _SET request means we want exactly the bits in the bitset to be set. This works correctly for compact format but when verbose format is parsed, ethnl_update_bitset32_verbose() only sets the bits present in the request bitset but does not clear the rest. The commit 6699170376ab ("ethtool: fix application of verbose no_mask bitset") fixes this issue by clearing the whole target bitmap before we start iterating. The solution proposed brought an issue with the behavior of the mod variable. As the bitset is always cleared the old value will always differ to the new value. Fix it by adding a new function to compare bitmaps and a temporary variable which save the state of the old bitmap.

If anyone has any objections, please let me know. ------------------ From: Amit Cohen <amcohen@nvidia.com> [ Upstream commit c2f3e10ac4ebf23e177226b9b4d297bfe2fb6b20 ] Currently virtual router ID element is broken to two sub-elements - 'VIRT_ROUTER_LSB' and 'VIRT_ROUTER_MSB'. It was broken as this field is broken in 'ipv4_4' flex key which is used for IPv4 in Spectrum < 4. For Spectrum-4, we use 'ipv4_4b' flex key which contains one field for virtual router, this key is not supported in older ASICs. Add 'ipv4_5' flex key which is supported in all ASICs and contains one field for virtual router. Then there is no reason to use 'VIRT_ROUTER_LSB' and 'VIRT_ROUTER_MSB', remove them and add one element 'VIRT_ROUTER' for this field. The motivation is to get rid of 'ipv4_4' flex key, as it might be chosen for IPv6 multicast forwarding region. This will not allow the improvement in a following patch. See more details in the cover letter and in a following patch.

Miller, Sasha Levin 6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Amit Cohen <amcohen@nvidia.com> [ Upstream commit 92953e7aab013719aa8974805614c0bc11361026 ] Two ACL regions that are configured by the driver during initialization are the ones used for IPv4 and IPv6 multicast forwarding. Entries residing in these two regions match on the {SIP, DIP, VRID} key elements. Currently for IPv6 region, 9 key blocks are used: * 4 for SIP - 'ipv4_1', 'ipv6_{3,4,5}' * 4 for DIP - 'ipv4_0', 'ipv6_{0,1,2/2b}' * 1 for VRID - 'ipv4_4b' This can be improved by reducing the amount key blocks needed for the IPv6 region to 8. It is possible to use key blocks that mix subsets of the VRID element with subsets of the DIP element. The following key blocks can be used: * 4 for SIP - 'ipv4_1', 'ipv6_{3,4,5}' * 1 for subset of DIP - 'ipv4_0' * 3 for the rest of DIP and subsets of VRID - 'ipv6_{0,1,2/2b}' To make this happen, add VRID sub-elements as part of existing keys - 'ipv6_{0,1,2/2b}'. Note that one of the sub-elements is called VRID_ROUTER_MSB and does not contain bit numbers like the rest, as for Spectrum < 4 this element represents bits 8-10 and for Spectrum-4 it represents bits 8-11. Breaking VRID into 3 sub-elements makes the driver use one less block in IPv6 region for multicast forwarding. The sub-elements can be filled in blocks that are used for destination IP. The algorithm in the driver that chooses which key blocks will be used is lazy and not the optimal one. It searches the block that contains the most elements that are required, chooses it, removes the elements that appear in the chosen block and starts again searching the block that contains the most elements. When key block 'ipv4_4' is defined, the algorithm might choose it, as it contains 2 sub-elements of VRID, then 8 blocks must be chosen for SIP and DIP and we get 9 blocks to match on {SIP, DIP, VRID}. That is why we had to remove key block 'ipv4_4' in a previous patch and use key block that contains one field for VRID. This improvement was tested and indeed 8 blocks are used instead of 9.

If anyone has any objections, please let me know. ------------------ From: Amit Cohen <amcohen@nvidia.com> [ Upstream commit cad6431b867507779c41b00baaf18382467ef0a0 ] For 12 key blocks in the A-TCAM, rules are split into two records, which constitute two lookups. The two records are linked using a "large entry key ID". Due to a Spectrum-4 hardware issue, KVD entries that correspond to key blocks 0 to 5 of 12 key blocks A-TCAM entries will be placed in the same KVD pipe if they only differ in their "large entry key ID", as it is ignored. This results in a reduced scale. To reduce the probability of this issue, we can place key blocks with high entropy in blocks 0 to 5. The idea is to place blocks that are changed often in blocks 0 to 5, for example, key blocks that match on IPv4 addresses or the LSBs of IPv6 addresses. Such placement will reduce the probability of these blocks to be same. Mark several blocks with 'high_entropy' flag, so later we will take into account this flag and place them in blocks 0 to 5.

If anyone has any objections, please let me know. ------------------ From: Ido Schimmel <idosch@nvidia.com> [ Upstream commit 217bbf156f93ada86b91617489e7ba8a0904233c ] The driver is currently using an ACL key block that is not supported by Spectrum-4. This works because the driver is only using a single field from this key block which is located in the same offset in the equivalent Spectrum-4 key block. The issue was discovered when the firmware started rejecting the use of the unsupported key block. The change has been reverted to avoid breaking users that only update their firmware. Nonetheless, fix the issue by using the correct key block.

It is triggered when offload a rule with tunnel encapsulation, and forwarding to another table, but not matching on the internal port in firmware steering mode. The original workaround skips internal tunnel port logic, which is not correct as not all cases are considered. As an example, if vlan is configured on the uplink port, traffic can't pass because vlan header is not added with this workaround. Besides, there is no such issue for software steering. So, this patch removes that, and returns error directly if trying to offload such rule for firmware steering.

After calling __rtnl_unlock() from netdev_run_todo(), we can not assume the netns of each device is still alive. Make sure the device is not in NETREG_UNREGISTERED state, and add an ASSERT_RTNL() before the call to __dev_get_by_index(). We might move this ASSERT_RTNL() in __dev_get_by_index() in the future.

Make kvm_handle_mmio_return() consistent with the exit handlers in handle_exit(). This makes the code easier to reason about, and makes it easier to add other handlers in future patches.

Womp womp. Fix the glaring UAPI bug by skipping over all the MMIO emulation in case there is a pending synchronous exception. Note that while userspace is capable of pending an asynchronous exception (SError, IRQ, or FIQ), it is still safe to retire the MMIO instruction in this case as (1) they are by definition asynchronous, and (2) KVM relies on hardware support for pending/delivering these exceptions instead of the software state machine for advancing PC.

This is so common that turn it into default behavior. xhci_warn_ratelimited() is no longer used after this, so remove it. A success event with untransferred bytes left doesn't always mean a misbehaving controller. If there was an error mid a multi-TRB TD it's allowed to issue a success event for the last TRB in that TD. See xhci 1.2 spec 4.9.1 Transfer Descriptors "Note: If an error is detected while processing a multi-TRB TD, the xHC shall generate a Transfer Event for the TRB that the error was detected on with the appropriate error Condition Code, then may advance to the next TD. If in the process of advancing to the next TD, a Transfer TRB is encountered with its IOC flag set, then the Condition Code of the Transfer Event generated for that Transfer TRB should be Success, because there was no error actually associated with the TRB that generated the Event. However, an xHC implementation may redundantly assert the original error Condition Code."

After the SetPortFeature(PORT_RESET) request is completed, the hub driver calls the HCD reset_device callback, which will issue a Reset Device command and free all structures associated with endpoints that were disabled. This happens when the xHCI driver issue a Reset Device command to inform the Etron xHCI host that the USB device associated with a device slot has been reset. Seems that the Etron xHCI host can not perform this command correctly, affecting the USB device. To work around this, the xHCI driver should obtain a new device slot with reference to commit 651aaf36a7d7 ("usb: xhci: Handle USB transaction error on address command"), which is another way to inform the Etron xHCI host that the USB device has been reset.

So far this has been ignored and the printk output is based on the principle of hope. The rework of the console infrastructure which aims to support threaded and atomic consoles, requires to mark sections which modify the UART registers as unsafe. This allows the atomic write function to make informed decisions and eventually to restore operational state. It also allows to prevent the regular UART code from modifying UART registers while printk output is in progress. All modifications of UART registers are guarded by the UART port lock, which provides an obvious synchronization point with the console infrastructure. To avoid adding this functionality to all UART drivers, wrap the spin_[un]lock*() invocations for uart_port::lock into helper functions which just contain the spin_[un]lock*() invocations for now. In a subsequent step these helpers will gain the console synchronization mechanisms. Converted with coccinelle. No functional change.

However, to properly unthrottle RX when DMA is used, the function pl011_unthrottle_rx() is expected to set the RXDMAE bit of the DMACR register, which it currently lacks. This causes RX to stall after the throttle API is called. Set RXDMAE bit in the DMACR register while unthrottling RX if RX DMA is used.

However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

In the QUICC Engine (QE) version, some operations done at probe() need to be done in a different order. In order to prepare the support for the QE version, changed the sequence of operation done at probe(): - Retrieve the tsa_serial earlier, before initializing resources. - Group SCC initialisation and do this initialization when it is really needed in the probe() sequence. Having the QE compatible sequence in the CPM1 version does not lead to any issue and works correctly without any regressions.

It does this command sequence: DEPSTARTCFG -> DEPXFERCFG -> DEPCFG Instead of the suggested flow: DEPSTARTCFG -> DEPCFG -> DEPXFERCFG The reasons for this deviation were as follow, quoted: 1) The databook says to do %DWC3_DEPCMD_DEPSTARTCFG for every %USB_REQ_SET_CONFIGURATION and %USB_REQ_SET_INTERFACE (8.1.5). This is incorrect in the scenario of multiple interfaces. 2) The databook does not mention doing more %DWC3_DEPCMD_DEPXFERCFG for new endpoint on alt setting (8.1.6). Regarding 1), DEPSTARTCFG resets the endpoints' resource and can be a problem if used with SET_INTERFACE request of a multiple interface configuration. But we can still satisfy the programming guide requirement by assigning the endpoint resource as part of usb_ep_enable(). We will only reset endpoint resources on controller initialization and SET_CONFIGURATION request. Regarding 2), the later versions of the programming guide were updated to clarify this flow (see "Alternate Initialization on SetInterface Request" of the programming guide). As long as the platform has enough physical endpoints, we can assign resource to a new endpoint. The order of the command sequence will not be a problem to most platforms for the current implementation of the dwc3 driver. However, this order is required in different scenarios (such as initialization during controller's hibernation restore). Let's keep the flow consistent and follow the programming guide.

This is - * incorrect in the scenario of multiple interfaces. - * - * 2) The databook does not mention doing more %DWC3_DEPCMD_DEPXFERCFG for new - * endpoint on alt setting (8.1.6). - * - * The following simplified method is used instead: + * dwc3_gadget_start_config - reset endpoint resources + * @dwc: pointer to the DWC3 context + * @resource_index: DEPSTARTCFG.XferRscIdx value (must be 0 or 2) * - * All hardware endpoints can be assigned a transfer resource and this setting - * will stay persistent until either a core reset or hibernation. So whenever we - * do a %DWC3_DEPCMD_DEPSTARTCFG(0) we can go ahead and do - * %DWC3_DEPCMD_DEPXFERCFG for every hardware endpoint as well. We are - * guaranteed that there are as many transfer resources as endpoints. + * Set resource_index=0 to reset all endpoints' resources allocation. Do this as + * part of the power-on/soft-reset initialization. * - * This function is called for each endpoint when it is being enabled but is - * triggered only when called for EP0-out, which always happens first, and which - * should only happen in one of the above conditions. + * Set resource_index=2 to reset only non-control endpoints' resources.

Unless the endpoint is reset, don't clear this flag. Otherwise we may set endpoint resource again, which prevents the driver from initiate transfer after handling a STALL or endpoint halt to the control endpoint. Commit f2e0eee47038 ("usb: dwc3: ep0: Don't reset resource alloc flag") was fixing the initial issue, but did this only for physical ep1. Since the function dwc3_ep0_stall_and_restart is resetting the flags for both physical endpoints, this also has to be done for ep0.

Namely ac-time is used for fine grained writeback of idle entries (pages). Move ac-time tracking under its own config option so that it can be enabled (along with writeback) on systems without DEBUG_FS.

Null pointer dereference occurs due to a race between smmu driver probe and client driver probe, when of_dma_configure() for client is called after the iommu_device_register() for smmu driver probe has executed but before the driver_bound() for smmu driver has been called. Following is how the race occurs: T1:Smmu device probe T2: Client device probe really_probe() arm_smmu_device_probe() iommu_device_register() really_probe() platform_dma_configure() of_dma_configure() of_dma_configure_id() of_iommu_configure() iommu_probe_device() iommu_init_device() arm_smmu_probe_device() arm_smmu_get_by_fwnode() driver_find_device_by_fwnode() driver_find_device() next_device() klist_next() /* null ptr assigned to smmu */ /* null ptr dereference while smmu->streamid_mask */ driver_bound() klist_add_tail() When this null smmu pointer is dereferenced later in arm_smmu_probe_device, the device crashes. Fix this by deferring the probe of the client device until the smmu device has bound to the arm smmu driver.

Due to an unsigned cast, adjtimex() returns the wrong offest when using ADJ_MICRO and the offset is negative. In this case a small negative offset returns approximately 4.29 seconds (~ 2^32/1000 milliseconds) due to the unsigned cast of the negative offset. This cast was added when the kernel internal struct timex was changed to use type long long for the time offset value to address the problem of a 64bit/32bit division on 32bit systems. The correct cast would have been (s32), which is correct as time_offset can only be in the range of [INT_MIN..INT_MAX] because the shift constant used for calculating it is 32. But that's non-obvious. Remove the cast and use div_s64() to cure the issue.

If that dependency doesn't exist, deleting the fwnode link once doesn't guarantee that it won't get created again. So, add FWLINK_FLAG_IGNORE flag to mark a fwnode link as one that needs to be completely ignored. Since a fwnode link's flags is an OR of all the flags passed to all the fwnode_link_add() calls to create that specific fwnode link, the FWLINK_FLAG_IGNORE flag is preserved and can be used to mark a fwnode link as on that need to be completely ignored until it is deleted.

Each fix has further narrowed the conditions for optimization. It's time to give up on these optimization attempts and just run the cycle detection logic every time fw_devlink tries to create a device link. The specific bug report that triggered this fix involved a supplier fwnode that never gets a device created for it. Instead, the supplier fwnode is represented by the device that corresponds to an ancestor fwnode. In this case, fw_devlink didn't do any cycle detection because the cycle detection logic is only run when a device link is created between the devices that correspond to the actual consumer and supplier fwnodes. With this change, fw_devlink will run cycle detection logic even when creating SYNC_STATE_ONLY proxy device links from a device that is an ancestor of a consumer fwnode.

Remove dev->info.dyn_addr != dev->boardinfo->init_dyn_addr condition check. dev->info.dyn_addr should be checked before calling this function because i3c_master_setnewda_locked() has already been called and the target device has already accepted dyn_addr. It is too late to check if dyn_addr is free in i3c_master_reattach_i3c_dev(). Add check to ensure expected_dyn_addr is free before i3c_master_setnewda_locked().

Since it is a "reset" and not an "enable" line, the GPIO should be asserted to put it in reset and deasserted to bring it out of reset during the power on sequence. The polarity was inverted when the driver was first introduced, likely because the device family that was targeted had an inverting level shifter on the reset line. The MT8186 Corsola devices already have the IT6505 in their device tree, but the whole display pipeline is actually disabled and won't be enabled until some remaining issues are sorted out. The other known user is the MT8183 Kukui / Jacuzzi family; their device trees currently do not have the IT6505 included. Fix the polarity in the driver while there are no actual users.

If anyone has any objections, please let me know. ------------------ From: Larysa Zaremba <larysa.zaremba@intel.com> [ Upstream commit ac9a48a6f1610b094072b815e884e1668aea4401 ] When the umem is shared, the DMA mapping is also shared between the xsk pools, therefore it should stay valid as long as at least 1 user remains. However, the pool also keeps the copies of DMA-related information that are initialized in the same way in xp_init_dma_info(), but cleared by xp_dma_unmap() only for the last remaining pool, this causes the problems below. The first one is that the commit adbf5a42341f ("ice: remove af_xdp_zc_qps bitmap") relies on pool->dev to determine the presence of a ZC pool on a given queue, avoiding internal bookkeeping. This works perfectly fine if the UMEM is not shared, but reliably fails otherwise as stated in the linked report. The second one is pool->dma_pages which is dynamically allocated and only freed in xp_dma_unmap(), this leads to a small memory leak. kmemleak does not catch it, but by printing the allocation results after terminating the userspace program it is possible to see that all addresses except the one belonging to the last detached pool are still accessible through the kmemleak dump functionality. Always clear the DMA mapping information from the pool and free pool->dma_pages when unmapping the pool, so that the only difference between results of the last remaining user's call and the ones before would be the destruction of the DMA mapping.

However, the function had a few issues and it brought to the incorrect states. Namely: - It tried to get a wrong sequencer info for the update without correcting the port number with the group-offset 1 - The loop exited immediately when a sequencer port isn't present; this ended up with the truncation if a sequencer port in the middle goes away This patch addresses those bugs.

The difference is, however, that no packet will be handled any longer after all queued packets are handled but no enough data is fed. In the case of implicit feedback mode, the capture-side packet handling triggers the re-queuing, and this checks the XRUN. OTOH, in the low-latency mode, it just stops without XRUN notification unless any new action is taken from user-space via ack callback. For example, when you stop the stream in aplay, no XRUN is reported. This patch adds the XRUN check at the packet complete callback in the case all pending URBs are exhausted. Strictly speaking, this state doesn't match really with XRUN; in theory the application may queue immediately after this happens. But such behavior is only for 1-period configuration, which the USB-audio driver doesn't support. So we may conclude that this situation leads certainly to XRUN. A caveat is that the XRUN should be triggered only for the PCM RUNNING state, and not during DRAINING. This additional state check is put in notify_xrun(), too.

Here, a bootstrap build is a build host variant of a target. E.g., assume that you're performing a bpftool cross-build on x86 to riscv, a bootstrap build would then be an x86 variant of bpftool. The typical way to perform the host build variant, is to pass "ARCH=" in a sub-make. However, if a variable has been set with a command argument, then ordinary assignments in the makefile are ignored. This side-effect results in that ARCH, and variables depending on ARCH are not set. Workaround by overriding ARCH to the host arch, if ARCH is empty.

However, in such a scenario, it rejects all partial stack overwrites as long as the targeted stack slot is a spilled register, because it does not check if the stack slot is a spilled pointer. Incomplete checks will result in the rejection of valid programs, which spill narrower scalar values onto scalar slots, as shown below. 0: R1=ctx() R10=fp0 ; asm volatile ( @ repro.bpf.c:679 0: (7a) *(u64 *)(r10 -8) = 1 ; R10=fp0 fp-8_w=1 1: (62) *(u32 *)(r10 -8) = 1 attempt to corrupt spilled pointer on stack processed 2 insns (limit 1000000) max_states_per_insn 0 total_states 0 peak_states 0 mark_read 0. Fix this by expanding the check to not consider spilled scalar registers when rejecting the write into the stack. Previous discussion on this patch is at link [0].

The kref_put() call may decrement the reference count of sfp to zero, triggering its cleanup through sg_remove_sfp(). This cleanup includes scheduling deferred work via sg_remove_sfp_usercontext(), which ultimately frees sfp. After kref_put(), sg_release() continues to unlock open_rel_lock and may reference sfp or sdp. If sfp has already been freed, this results in a slab-use-after-free error. Move the kref_put(&sfp->f_ref, sg_remove_sfp) call after unlocking the open_rel_lock mutex. This ensures: - No references to sfp or sdp occur after the reference count is decremented. - Cleanup functions such as sg_remove_sfp() and sg_remove_sfp_usercontext() can safely execute without impacting the mutex handling in sg_release(). The fix has been tested and validated by syzbot. This patch closes the bug reported at the following syzkaller link and ensures proper sequencing of resource cleanup and mutex operations, eliminating the risk of use-after-free errors in sg_release().

As a result, their values accumulate until they overflow. The expected behavior is for performance counters to reset to zero at the start of a job. When the job finishes and the perfmon is stopped, the counters should accurately reflect the values for that specific job. To ensure this behavior, the performance counters are now enabled before being cleared. This allows the CLR register to function as intended, zeroing the counter values when the job begins.

If anyone has any objections, please let me know. ------------------ From: Jakob Hauser <jahau@rocketmail.com> [ Upstream commit f1ee5483e40881d8ad5a63aa148b753b5c6a839b ] In the function yas537_measure() there is a clamp_val() with limits of -BIT(13) and BIT(13) - 1. The input clamp value h[] is of type s32. The BIT() is of type unsigned long integer due to its define in include/vdso/bits.h. The lower limit -BIT(13) is recognized as -8192 but expressed as an unsigned long integer. The size of an unsigned long integer differs between 32-bit and 64-bit architectures. Converting this to type s32 may lead to undesired behavior. Additionally, in the calculation lines h[0], h[1] and h[2] the unsigned long integer divisor BIT(13) causes an unsigned division, shifting the left-hand side of the equation back and forth, possibly ending up in large positive values instead of negative values on 32-bit architectures. To solve those two issues, declare a signed integer with a value of BIT(13). There is another omission in the clamp line: clamp_val() returns a value and it's going nowhere here. Self-assign it to h[i] to make use of the clamp macro. Finally, replace clamp_val() macro by clamp() because after changing the limits from type unsigned long integer to signed integer it's fine that way.

It will return expected result when the passed key exist in the trie. However when a recently-deleted key or nonexistent key is passed to trie_get_next_key(), it may skip keys and return incorrect result. Fix it by using node->prefixlen == matchlen to identify exact matches. When the condition is true after the search, it also implies node->prefixlen equals key->prefixlen, otherwise, the search would return NULL instead.

Fix it by moving the mlocked flag clearance down to free_page_prepare(). The bug itself if fairly old and harmless (aside from generating these warnings), aside from a small memory leak - "bad" pages are stopped from being allocated again.

And it should be the same with invalid pmd entry, since pmd_none() is called by function free_pgd_range() and pmd_none() return 0 by huge_pte_clear(). So single _PAGE_HUGE bit is also treated as a valid pte table and free_pte_range() will be called in free_pmd_range(). free_pmd_range() pmd = pmd_offset(pud, addr); do { next = pmd_addr_end(addr, end); if (pmd_none_or_clear_bad(pmd)) continue; free_pte_range(tlb, pmd, addr); } while (pmd++, addr = next, addr != end); Here invalid_pte_table is used for both invalid huge pte entry and pmd entry.

Commit b8e0ddd36ce9 ("can: mcp251xfd: tef: prepare to workaround broken TEF FIFO tail index erratum") introduced mcp251xfd_get_tef_len() to get the number of unhandled transmit events from the Transmit Event FIFO (TEF). As the TEF has no head index, the driver uses the TX-FIFO's tail index instead, assuming that send frames are completed. When calculating the number of unhandled TEF events, that commit didn't take mcp2518fd erratum DS80000789E 6. into account. According to that erratum, the FIFOCI bits of a FIFOSTA register, here the TX-FIFO tail index might be corrupted. However here it seems the bit indicating that the TX-FIFO is empty (MCP251XFD_REG_FIFOSTA_TFERFFIF) is not correct while the TX-FIFO tail index is. Assume that the TX-FIFO is indeed empty if: - Chip's head and tail index are equal (len == 0). - The TX-FIFO is less than half full. (The TX-FIFO empty case has already been checked at the beginning of this function.) - No free buffers in the TX ring. If the TX-FIFO is assumed to be empty, assume that the TEF is full and return the number of elements in the TX-FIFO (which equals the number of TEF elements). If these assumptions are false, the driver might read to many objects from the TEF. mcp251xfd_handle_tefif_one() checks the sequence numbers and will refuse to process old events.

The cmp_entries_dup() function used as the comparator for sort() violated the symmetry and transitivity properties required by the sorting algorithm. Specifically, it returned 1 whenever memcmp() was non-zero, which broke the following expectations: * Symmetry: If x < y, then y > x. * Transitivity: If x < y and y < z, then x < z. These violations could lead to incorrect sorting and failure to correctly identify duplicate elements. Fix the issue by directly returning the result of memcmp(), which adheres to the required comparison properties.

If anyone has any objections, please let me know. ------------------ From: Catalin Marinas <catalin.marinas@arm.com> commit c0900d15d31c2597dd9f634c8be2b71762199890 upstream. Linux currently sets the TCR_EL1.AS bit unconditionally during CPU bring-up. On an 8-bit ASID CPU, this is RES0 and ignored, otherwise 16-bit ASIDs are enabled. However, if running in a VM and the hypervisor reports 8-bit ASIDs (ID_AA64MMFR0_EL1.ASIDBits == 0) on a 16-bit ASIDs CPU, Linux uses bits 8 to 63 as a generation number for tracking old process ASIDs. The bottom 8 bits of this generation end up being written to TTBR1_EL1 and also used for the ASID-based TLBI operations as the upper 8 bits of the ASID. Following an ASID roll-over event we can have threads of the same application with the same 8-bit ASID but different generation numbers running on separate CPUs. Both TLB caching and the TLBI operations will end up using different actual 16-bit ASIDs for the same process. A similar scenario can happen in a big.LITTLE configuration if the boot CPU only uses 8-bit ASIDs while secondary CPUs have 16-bit ASIDs. Ensure that the ASID generation is only tracked by bits 16 and up, leaving bits 15:8 as 0 if the kernel uses 8-bit ASIDs. Note that clearing TCR_EL1.AS is not sufficient since the architecture requires that the top 8 bits of the ASID passed to TLBI instructions are 0 rather than ignored in such configuration.

If anyone has any objections, please let me know. ------------------ From: Mark Rutland <mark.rutland@arm.com> commit ca62d90085f4af36de745883faab9f8a7cbb45d3 upstream. Currently tagged_addr_ctrl_set() doesn't initialize the temporary 'ctrl' variable, and a SETREGSET call with a length of zero will leave this uninitialized. Consequently tagged_addr_ctrl_set() will consume an arbitrary value, potentially leaking up to 64 bits of memory from the kernel stack. The read is limited to a specific slot on the stack, and the issue does not provide a write mechanism. As set_tagged_addr_ctrl() only accepts values where bits [63:4] zero and rejects other values, a partial SETREGSET attempt will randomly succeed or fail depending on the value of the uninitialized value, and the exposure is significantly limited. Fix this by initializing the temporary value before copying the regset from userspace, as for other regsets (e.g. NT_PRSTATUS, NT_PRFPREG, NT_ARM_SYSTEM_CALL). In the case of a zero-length write, the existing value of the tagged address ctrl will be retained. The NT_ARM_TAGGED_ADDR_CTRL regset is only visible in the user_aarch64_view used by a native AArch64 task to manipulate another native AArch64 task. As get_tagged_addr_ctrl() only returns an error value when called for a compat task, tagged_addr_ctrl_get() and tagged_addr_ctrl_set() should never observe an error value from get_tagged_addr_ctrl(). Add a WARN_ON_ONCE() to both to indicate that such an error would be unexpected, and error handlnig is not missing in either case.

Abort the outstanding bsg/SRB and wait for the completion. The completion IOCB will wake up the bsg_timeout thread. If abort is not successful, then driver will forcibly call bsg_job_done() and free the srb.

The cause of the issue is NPIV host did not initialize the vha->irq_offset field. This field is given to blk-mq (blk_mq_pci_map_queues) to help locate the beginning of IO Queues which in turn help locate NVMe queue 0.

System crash is observed with stack trace warning of use after free. There are 2 signals to tell dpc_thread to terminate (UNLOADING flag and kthread_stop). On setting the UNLOADING flag when dpc_thread happens to run at the time and sees the flag, this causes dpc_thread to exit and clean up itself. When kthread_stop is called for final cleanup, this causes use after free. Remove UNLOADING signal to terminate dpc_thread. Use the kthread_stop as the main signal to exit dpc_thread.

Syzbot reported that when searching for records in a directory where the inode's i_size is corrupted and has a large value, memory access outside the folio/page range may occur, or a use-after-free bug may be detected if KASAN is enabled. This is because nilfs_last_byte(), which is called by nilfs_find_entry() and others to calculate the number of valid bytes of directory data in a page from i_size and the page index, loses the upper 32 bits of the 64-bit size information due to an inappropriate type of local variable to which the i_size value is assigned. This caused a large byte offset value due to underflow in the end address calculation in the calling nilfs_find_entry(), resulting in memory access that exceeds the folio/page size. Fix this issue by changing the type of the local variable causing the bit loss from "unsigned int" to "u64". The return value of nilfs_last_byte() is also of type "unsigned int", but it is truncated so as not to exceed PAGE_SIZE and no bit loss occurs, so no change is required.

If anyone has any objections, please let me know. ------------------ From: Ricardo Neri <ricardo.neri-calderon@linux.intel.com> commit b3fce429a1e030b50c1c91351d69b8667eef627b upstream. Commit 5944ce092b97 ("arch_topology: Build cacheinfo from primary CPU") adds functionality that architectures can use to optionally allocate and build cacheinfo early during boot. Commit 6539cffa9495 ("cacheinfo: Add arch specific early level initializer") lets secondary CPUs correct (and reallocate memory) cacheinfo data if needed. If the early build functionality is not used and cacheinfo does not need correction, memory for cacheinfo is never allocated. x86 does not use the early build functionality. Consequently, during the cacheinfo CPU hotplug callback, last_level_cache_is_valid() attempts to dereference a NULL pointer: BUG: kernel NULL pointer dereference, address: 0000000000000100 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not present page PGD 0 P4D 0 Oops: 0000 [#1] PREEPMT SMP NOPTI CPU: 0 PID 19 Comm: cpuhp/0 Not tainted 6.4.0-rc2 #1 RIP: 0010: last_level_cache_is_valid+0x95/0xe0a Allocate memory for cacheinfo during the cacheinfo CPU hotplug callback if not done earlier. Moreover, before determining the validity of the last-level cache info, ensure that it has been allocated. Simply checking for non-zero cache_leaves() is not sufficient, as some architectures (e.g., Intel processors) have non-zero cache_leaves() before allocation. Dereferencing NULL cacheinfo can occur in update_per_cpu_data_slice_size(). This function iterates over all online CPUs. However, a CPU may have come online recently, but its cacheinfo may not have been allocated yet. While here, remove an unnecessary indentation in allocate_cache_info().

If anyone has any objections, please let me know. ------------------ From: Imre Deak <imre.deak@intel.com> commit bd2fccac61b40eaf08d9546acc9fef958bfe4763 upstream. Fix the MST sideband message body length check, which must be at least 1 byte accounting for the message body CRC (aka message data CRC) at the end of the message. This fixes a case where an MST branch device returns a header with a correct header CRC (indicating a correctly received body length), with the body length being incorrectly set to 0. This will later lead to a memory corruption in drm_dp_sideband_append_payload() and the following errors in dmesg: UBSAN: array-index-out-of-bounds in drivers/gpu/drm/display/drm_dp_mst_topology.c:786:25 index -1 is out of range for type 'u8 [48]' Call Trace: drm_dp_sideband_append_payload+0x33d/0x350 [drm_display_helper] drm_dp_get_one_sb_msg+0x3ce/0x5f0 [drm_display_helper] drm_dp_mst_hpd_irq_handle_event+0xc8/0x1580 [drm_display_helper] memcpy: detected field-spanning write (size 18446744073709551615) of single field "&msg->msg[msg->curlen]" at drivers/gpu/drm/display/drm_dp_mst_topology.c:791 (size 256) Call Trace: drm_dp_sideband_append_payload+0x324/0x350 [drm_display_helper] drm_dp_get_one_sb_msg+0x3ce/0x5f0 [drm_display_helper] drm_dp_mst_hpd_irq_handle_event+0xc8/0x1580 [drm_display_helper] Cc: <stable@vger.kernel.org> Cc: Lyude Paul <lyude@redhat.com> Reviewed-by: Lyude Paul <lyude@redhat.com> Signed-off-by: Imre Deak <imre.deak@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20241125205314.1725887-1-imre.deak@intel.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> --- drivers/gpu/drm/display/drm_dp_mst_topology.c | 3 +++ 1 file changed, 3 insertions(+) --- a/drivers/gpu/drm/display/drm_dp_mst_topology.c +++ b/drivers/gpu/drm/display/drm_dp_mst_topology.c @@ -319,6 +319,9 @@ static bool drm_dp_decode_sideband_msg_h hdr->broadcast = (buf[idx] >> 7) & 0x1; hdr->path_msg = (buf[idx] >> 6) & 0x1; hdr->msg_len = buf[idx] & 0x3f; + if (hdr->msg_len < 1) /* min space for body CRC */ + return false; + idx++; hdr->somt = (buf[idx] >> 7) & 0x1; hdr->eomt = (buf[idx] >> 6) & 0x1; ^ permalink raw reply [flat|nested] 370+ messages in thread

After receiving the response for an MST down request message, the response should be accepted/parsed only if the response type matches that of the request. Ensure this by checking if the request type code stored both in the request and the reply match, dropping the reply in case of a mismatch. This fixes the topology detection for an MST hub, as described in the Closes link below, where the hub sends an incorrect reply message after a CLEAR_PAYLOAD_TABLE -> LINK_ADDRESS down request message sequence.

If the MST topology is removed during the reception of an MST down reply or MST up request sideband message, the drm_dp_mst_topology_mgr::up_req_recv/down_rep_recv states could be reset from one thread via drm_dp_mst_topology_mgr_set_mst(false), racing with the reading/parsing of the message from another thread via drm_dp_mst_handle_down_rep() or drm_dp_mst_handle_up_req(). The race is possible since the reader/parser doesn't hold any lock while accessing the reception state. This in turn can lead to a memory corruption in the reader/parser as described by commit bd2fccac61b4 ("drm/dp_mst: Fix MST sideband message body length check"). Fix the above by resetting the message reception state if needed before reading/parsing a message. Another solution would be to hold the drm_dp_mst_topology_mgr::lock for the whole duration of the message reception/parsing in drm_dp_mst_handle_down_rep() and drm_dp_mst_handle_up_req(), however this would require a bigger change. Since the fix is also needed for stable, opting for the simpler solution in this patch.

Fix is simple as changing the type from int to u32, however, when compared to XSKMAP case, one more thing needs to be addressed. When map is released from system via dev_map_free(), we iterate through all of the entries and an iterator variable is also an int, which implies OOB accesses. Again, change it to be u32.

If anyone has any objections, please let me know. ------------------ From: Tvrtko Ursulin <tvrtko.ursulin@igalia.com> commit fe52c649438b8489c9456681d93a9b3de3d38263 upstream. One alternative to the fix Christian proposed in https://lore.kernel.org/dri-devel/20241024124159.4519-3-christian.koenig@amd.com/ is to replace the rather complex open coded sorting loops with the kernel standard sort followed by a context squashing pass. Proposed advantage of this would be readability but one concern Christian raised was that there could be many fences, that they are typically mostly sorted, and so the kernel's heap sort would be much worse by the proposed algorithm. I had a look running some games and vkcube to see what are the typical number of input fences. Tested scenarios: 1) Hogwarts Legacy under Gamescope 450 calls per second to __dma_fence_unwrap_merge. Percentages per number of fences buckets, before and after checking for signalled status, sorting and flattening: N Before After 0 0.91% 1 69.40% 2-3 28.72% 9.4% (90.6% resolved to one fence) 4-5 0.93% 6-9 0.03% 10+ 2) Cyberpunk 2077 under Gamescope 1050 calls per second, amounting to 0.01% CPU time according to perf top. N Before After 0 1.13% 1 52.30% 2-3 40.34% 55.57% 4-5 1.46% 0.50% 6-9 2.44% 10+ 2.34% 3) vkcube under Plasma 90 calls per second. N Before After 0 1 2-3 100% 0% (Ie. all resolved to a single fence) 4-5 6-9 10+ In the case of vkcube all invocations in the 2-3 bucket were actually just two input fences. >From these numbers it looks like the heap sort should not be a disadvantage, given how the dominant case is <= 2 input fences which heap sort solves with just one compare and swap. (And for the case of one input fence we have a fast path in the previous patch.) A complementary possibility is to implement a different sorting algorithm under the same API as the kernel's sort() and so keep the simplicity, potentially moving the new sort under lib/ if it would be found more widely useful. v2: * Hold on to fence references and reduce commentary. (Christian) * Record and use latest signaled timestamp in the 2nd loop too. * Consolidate zero or one fences fast paths. v3: * Reverse the seqno sort order for a simpler squashing pass.

Jordy says: " In the xsk_map_delete_elem function an unsigned integer (map->max_entries) is compared with a user-controlled signed integer (k). Due to implicit type conversion, a large unsigned value for map->max_entries can bypass the intended bounds check: if (k >= map->max_entries) return -EINVAL; This allows k to hold a negative value (between -2147483648 and -2), which is then used as an array index in m->xsk_map[k], which results in an out-of-bounds access. spin_lock_bh(&m->lock); map_entry = &m->xsk_map[k]; // Out-of-bounds map_entry old_xs = unrcu_pointer(xchg(map_entry, NULL)); // Oob write if (old_xs) xsk_map_sock_delete(old_xs, map_entry); spin_unlock_bh(&m->lock); The xchg operation can then be used to cause an out-of-bounds write. Moreover, the invalid map_entry passed to xsk_map_sock_delete can lead to further memory corruption.

At the end of __regmap_init(), if dev is not NULL, regmap_attach_dev() is called, which adds a devres reference to the regmap, to be able to retrieve a dev's regmap by name using dev_get_regmap(). When calling regmap_exit, the opposite does not happen, and the reference is kept until the dev is detached. Add a regmap_detach_dev() function and call it in regmap_exit() to make sure that the devres reference is not kept.

Disabling card detect from the host's ->shutdown_pre() callback turned out to not be the complete solution. More precisely, beyond the point when the mmc_bus->shutdown() has been called, to gracefully power off the card, we need to prevent card detect. Otherwise the mmc_rescan work may poll for the card with a CMD13, to see if it's still alive, which then will fail and hang as the card has already been powered off. To fix this problem, let's disable mmc_rescan prior to power off the card during shutdown.

If anyone has any objections, please let me know. ------------------ From: David Woodhouse <dwmw@amazon.co.uk> commit d0ceea662d459726487030237689835fcc0483e5 upstream. The set_p4d() and set_pgd() functions (in 4-level or 5-level page table setups respectively) assume that the root page table is actually a 8KiB allocation, with the userspace root immediately after the kernel root page table (so that the former can enforce NX on on all the subordinate page tables, which are actually shared). However, users of the kernel_ident_mapping_init() code do not give it an 8KiB allocation for its PGD. Both swsusp_arch_resume() and acpi_mp_setup_reset() allocate only a single 4KiB page. The kexec code on x86_64 currently gets away with it purely by chance, because it allocates 8KiB for its "control code page" and then actually uses the first half for the PGD, then copies the actual trampoline code into the second half only after the identmap code has finished scribbling over it. Fix this by defining a _PAGE_NOPTISHADOW bit (which can use the same bit as _PAGE_SAVED_DIRTY since one is only for the PGD/P4D root and the other is exclusively for leaf PTEs.). This instructs __pti_set_user_pgtbl() not to write to the userspace 'shadow' PGD. Strictly, the _PAGE_NOPTISHADOW bit doesn't need to be written out to the actual page tables; since __pti_set_user_pgtbl() returns the value to be written to the kernel page table, it could be filtered out. But there seems to be no benefit to actually doing so.

CPUHP_AP_PERF_ONLINE --> perf_event_exit_cpu() The s390 CPUMF sampling CPU hotplug handler invokes: s390_pmu_sf_offline_cpu() +--> cpusf_pmu_setup() +--> setup_pmc_cpu() +--> deallocate_buffers() This function de-allocates all sampling data buffers (SDBs) allocated for that CPU at event initialization. It also clears the PMU_F_RESERVED bit. The CPU is gone and can not be sampled. With the event still being active on the removed CPU, the CPU event hotplug support in kernel performance subsystem triggers the following function calls on the removed CPU: perf_event_exit_cpu() +--> perf_event_exit_cpu_context() +--> __perf_event_exit_context() +--> __perf_remove_from_context() +--> event_sched_out() +--> cpumsf_pmu_del() +--> cpumsf_pmu_stop() +--> hw_perf_event_update() to stop and remove the event. During removal of the event, the sampling device driver tries to read out the remaining samples from the sample data buffers (SDBs). But they have already been freed (and may have been re-assigned). This may lead to a use after free situation in which case the samples are most likely invalid. In the best case the memory has not been reassigned and still contains valid data. Remedy this situation and check if the CPU is still in reserved state (bit PMU_F_RESERVED set). In this case the SDBs have not been released an contain valid data. This is always the case when the event is removed (and no CPU hotplug off occured). If the PMU_F_RESERVED bit is not set, the SDB buffers are gone.

[CAUSE] Inside device_list_add(), we are using a very primitive way checking if the device has changed, strcmp(). Which can never handle links well, no matter if it's hard or soft links. So every different link of the same device will be treated as a different device, causing the unnecessary device path update. [FIX] Introduce a helper, is_same_device(), and use path_equal() to properly detect the same block device. So that the different soft links won't trigger the rename race.

The device add somewhat surprisingly clears the readonly bit on the sb (though the mount is still practically readonly, from the users perspective...). Finally, the remount checks the readonly bit on the sb against the flag and sees no change, so it does not run the code intended to run on ro->rw transitions, leaving BTRFS_FS_OPEN unset. As a result, when the cleaner_kthread runs, it sees no BTRFS_FS_OPEN and does no work. This results in leaking deleted snapshots until we run out of space. I propose fixing it at the first departure from what feels reasonable: when we clear the readonly bit on the sb during device add. A new fstest I have written reproduces the bug and confirms the fix.

That list is protected by the report_filterlist_lock *non-raw* spinlock which may sleep on RT kernels. Since KCSAN may report data races in any context, convert it to a raw_spinlock. This requires being careful about when to allocate memory for the filter list itself which can be done via KCSAN's debugfs interface. Concurrent modification of the filter list via debugfs should be rare: the chosen strategy is to optimistically pre-allocate memory before the critical section and discard if unused.

On top of that this tablet is special because all its LPSS island peripherals are enumerated as PCI devices rather then as ACPI devices as they typically are. For the x86-android-tablets kmod to be able to instantiate a serdev client for the Bluetooth HCI on this tablet, an ACPI_QUIRK_UART1_SKIP quirk is necessary. Modify acpi_dmi_skip_serdev_enumeration() to work with PCI enumerated UARTs without an UID, such as the UARTs on this tablet. Also make acpi_dmi_skip_serdev_enumeration() exit early if there are no quirks, since there is nothing to do then. And add the necessary quirks for the Vexia EDU ATLA 10 tablet. This should compile with CONFIG_PCI being unset without issues because dev_is_pci() is defined as "(false)" then.

Track the bits that are being leaked, and only warn when a new bit is set.

Flush Cache bit never gets cleared in sd_flush_cache() and Poweroff Notification Ready bit also never gets set to 1 within 1 second from the end of busy of CMD49 in sd_poweroff_notify(). This leads to I/O error and runtime PM error state. I observed that the same card manufactured on 01/2024 works as expected. This problem seems similar to the Kingston cards fixed with commit c467c8f08185 ("mmc: Add MMC_QUIRK_BROKEN_SD_CACHE for Kingston Canvas Go Plus from 11/2019") and should be handled using quirks. CID for the problematic card is here. 12345641535443002000000145016200 Manufacturer ID is 0x12 and defined as CID_MANFID_GIGASTONE as of now, but would like comments on what naming is appropriate because MID list is not public and not sure it's right.

This was not detected during regular testing without driver_async_probe. Convert the SoC code to platform driver and instantiate a platform device in its current device_initcall() to probe the platform driver. Rework .soc_revision callback to always return valid error code and return SoC revision via parameter. This way, if anything in the .soc_revision callback return -EPROBE_DEFER, it gets propagated to .probe and the .probe will get retried later.

The MBM and MBA tests need to discover the event and umask with which to configure the performance event used to measure read memory bandwidth. This is done by parsing the contents of /sys/bus/event_source/devices/uncore_imc_<imc instance>/events/cas_count_read Similarly, the resctrl selftests discover the cache size via /sys/bus/cpu/devices/cpu<id>/cache/index<index>/size. Take care to do bounds checking when using fscanf() to read the contents of files into a string buffer because by default fscanf() assumes arbitrarily long strings. If the file contains more bytes than the array can accommodate then an overflow will occur. Provide a maximum field width to the conversion specifier to protect against array overflow. The maximum is one less than the array size because string input stores a terminating null byte that is not covered by the maximum field width.

Another issue is that a resource name could be a non printable bytearray and we cannot assume to be ASCII coded. The log functionality is probably never being hit when DLM is used in normal way and no debug logging is enabled. The null pointer dereference can only occur on a new created lkb that does not have the resource assigned yet, it probably never hits the null pointer dereference but we should be sure that other changes might not change this behaviour and we actually can hit the mentioned null pointer dereference.

If anyone has any objections, please let me know. ------------------ From: Takashi Iwai <tiwai@suse.de> [ Upstream commit 5b1913a79c3e0518d9c5db343fa9fc4edcea041f ] For allowing the primary codec SSID matching (that works around the conflicting PCI SSID problems), introduce a new struct hda_quirk, which is compatible with the existing struct snd_pci_quirk along with new helper functions and macros. The existing snd_pci_quirk tables are replaced with hda_quirk tables accordingly, while keeping SND_PCI_QUIRK() entry definitions as is. This patch shouldn't bring any behavior change, just some renaming and shifting the code. The actual change for the codec SSID matching will follow after this.

Opening an fd from dentry can fail for several reasons. For example, when tasks are gone and we try to open their /proc files or we try to open a WRONLY file like in sysfs or when trying to open a file that was deleted on the remote network server. Add a new flag FAN_REPORT_FD_ERROR for fanotify_init(). For a group with FAN_REPORT_FD_ERROR, we will send the event with the error instead of the open fd, otherwise userspace may not get the error at all. For an overflow event, we report -EBADF to avoid confusing FAN_NOFD with -EPERM. Similarly for pidfd open errors we report either -ESRCH or the open error instead of FAN_NOPIDFD and FAN_EPIDFD. In any case, userspace will not know which file failed to open, so add a debug print for further investigation.

Unfortunately, the function can also not set some struct members such as job->sched. This could theoretically lead to UB by users dereferencing the struct's pointer members too early. It is easier to debug such issues if these pointers are initialized to NULL, so dereferencing them causes a NULL pointer exception. Accordingly, drm_sched_entity_init() does precisely that and initializes its struct with memset(). Initialize parameter "job" to 0 in drm_sched_job_init().

The commit f9dac92ba908 ("virtio_ring: enable premapped mode whatever use_dma_api") introduced this problem. And we reverted some commits to fix this in last linux version. Now we try to enable it and fix this bug directly. Here, when the frag size is not enough, we reduce the buffer len to fix this problem.

If anyone has any objections, please let me know. ------------------ From: Takashi Iwai <tiwai@suse.de> [ Upstream commit d6e6b9218ced5249b9136833ef5ec3f554ec7fde ] It seems that many webcams have buggy firmware and don't expose the mic capture volume with the proper resolution. We have workarounds in mixer.c, but judging from the numbers, those can be better managed as global quirk flags.

The problem is the number of entries in the pre-allocated sgtable, it is nents = max(rxglom_size, txglom_size) + max(rxglom_size, txglom_size) >> 4 + 1. Given the default [rt]xglom_size=32 it's actually 35 which is too small. Worst case, the pkt queue can end up with 64 SKBs. This occurs when a new SKB is added for each original SKB if tailroom isn't enough to hold tail_pad. At least one sg entry is needed for each SKB. So, eventually the "skb_queue_walk loop" in brcmf_sdiod_sglist_rw may run out of sg entries. This makes sg_next return NULL and this causes the oops. The patch sets nents to max(rxglom_size, txglom_size) * 2 to be able handle the worst-case. Btw. this requires only 64-35=29 * 16 (or 20 if CONFIG_NEED_SG_DMA_LENGTH) = 464 additional bytes of memory.

However, bpf_map_fd_put_ptr() is invoked while holding a bucket lock (raw_spin_lock_t), and bpf_map_free_id() attempts to acquire map_idr_lock (spinlock_t), triggering the following lockdep warning: ============================= [ BUG: Invalid wait context ] 6.11.0-rc4+ #49 Not tainted ----------------------------- test_maps/4881 is trying to lock: ffffffff84884578 (map_idr_lock){+...}-{3:3}, at: bpf_map_free_id.part.0+0x21/0x70 other info that might help us debug this: context-{5:5} 2 locks held by test_maps/4881: #0: ffffffff846caf60 (rcu_read_lock){....}-{1:3}, at: bpf_fd_htab_map_update_elem+0xf9/0x270 #1: ffff888149ced148 (&htab->lockdep_key#2){....}-{2:2}, at: htab_map_update_elem+0x178/0xa80 stack backtrace: CPU: 0 UID: 0 PID: 4881 Comm: test_maps Not tainted 6.11.0-rc4+ #49 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), ...

However, bpf_map_alloc_id() invokes idr_alloc_cyclic() after acquiring map_idr_lock, it will trigger a similar lockdep warning because the slab's lock (s->cpu_slab->lock) is still a spinlock. Instead of changing map_idr_lock's type, fix the issue by invoking htab_put_fd_value() after htab_unlock_bucket(). However, only deferring the invocation of htab_put_fd_value() is not enough, because the old map pointers in htab of maps can not be saved during batched deletion. Therefore, also defer the invocation of free_htab_elem(), so these to-be-freed elements could be linked together similar to lru map. There are four callers for ->map_fd_put_ptr: (1) alloc_htab_elem() (through htab_put_fd_value()) It invokes ->map_fd_put_ptr() under a raw_spinlock_t. The invocation of htab_put_fd_value() can not simply move after htab_unlock_bucket(), because the old element has already been stashed in htab->extra_elems. It may be reused immediately after htab_unlock_bucket() and the invocation of htab_put_fd_value() after htab_unlock_bucket() may release the newly-added element incorrectly. Therefore, saving the map pointer of the old element for htab of maps before unlocking the bucket and releasing the map_ptr after unlock. Beside the map pointer in the old element, should do the same thing for the special fields in the old element as well. (2) free_htab_elem() (through htab_put_fd_value()) Its caller includes __htab_map_lookup_and_delete_elem(), htab_map_delete_elem() and __htab_map_lookup_and_delete_batch(). For htab_map_delete_elem(), simply invoke free_htab_elem() after htab_unlock_bucket(). For __htab_map_lookup_and_delete_batch(), just like lru map, linking the to-be-freed element into node_to_free list and invoking free_htab_elem() for these element after unlock. It is safe to reuse batch_flink as the link for node_to_free, because these elements have been removed from the hash llist. Because htab of maps doesn't support lookup_and_delete operation, __htab_map_lookup_and_delete_elem() doesn't have the problem, so kept it as is. (3) fd_htab_map_free() It invokes ->map_fd_put_ptr without raw_spinlock_t. (4) bpf_fd_htab_map_update_elem() It invokes ->map_fd_put_ptr without raw_spinlock_t. After moving free_htab_elem() outside htab bucket lock scope, using pcpu_freelist_push() instead of __pcpu_freelist_push() to disable the irq before freeing elements, and protecting the invocations of bpf_mem_cache_free() with migrate_{disable|enable} pair.

The err variable is not cleared, so if we find no table to dump we will return the validation error even if user did not want strict checking. I think the only way to hit this is to send an buggy request, and ask for a table which doesn't exist, so there's no point treating this as a real fix. I only noticed it because a syzbot repro depended on it to trigger another bug.

While no RCU read lock is held in this context, we should still use proper RCU primitives for consistency and correctness. Replace the direct NULL check with rcu_access_pointer(), which is the appropriate primitive when only checking for NULL without dereferencing the pointer. This function provides the necessary ordering guarantees without requiring RCU read-side protection.

If anyone has any objections, please let me know. ------------------ From: Tomas Glozar <tglozar@redhat.com> [ Upstream commit 4eba4723c5254ba8251ecb7094a5078d5c300646 ] Most fields of struct timerlat_top_cpu are unsigned long long, but the fields {irq,thread,user}_count are int (32-bit signed). This leads to overflow when tracing on a large number of CPUs for a long enough time: $ rtla timerlat top -a20 -c 1-127 -d 12h ... 0 12:00:00 | IRQ Timer Latency (us) | Thread Timer Latency (us) CPU COUNT | cur min avg max | cur min avg max 1 #43200096 | 0 0 1 2 | 3 2 6 12 ... 127 #43200096 | 0 0 1 2 | 3 2 5 11 ALL #119144 e4 | 0 5 4 | 2 28 16 The average latency should be 0-1 for IRQ and 5-6 for thread, but is reported as 5 and 28, about 4 to 5 times more, due to the count overflowing when summed over all CPUs: 43200096 * 127 = 5486412192, however, 1191444898 (= 5486412192 mod MAX_INT) is reported instead, as seen on the last line of the output, and the averages are thus ~4.6 times higher than they should be (5486412192 / 1191444898 = ~4.6). Fix the issue by changing {irq,thread,user}_count fields to unsigned long long, similarly to other fields in struct timerlat_top_cpu and to the count variable in timerlat_top_print_sum.

In the performance test scenario, function irq_wait_for_interrupt() will always return 0 if lots of interrupts occurs and the CPU will be continuously consumed.

If anyone has any objections, please let me know. ------------------ From: Andrii Nakryiko <andrii@kernel.org> [ Upstream commit f44ec8733a8469143fde1984b5e6931b2e2f6f3f ] In general, BPF link's underlying BPF program should be considered to be reachable through attach hook -> link -> prog chain, and, pessimistically, we have to assume that as long as link's memory is not safe to free, attach hook's code might hold a pointer to BPF program and use it. As such, it's not (generally) correct to put link's program early before waiting for RCU GPs to go through. More eager bpf_prog_put() that we currently do is mostly correct due to BPF program's release code doing similar RCU GP waiting, but as will be shown in the following patches, BPF program can be non-sleepable (and, thus, reliant on only "classic" RCU GP), while BPF link's attach hook can have sleepable semantics and needs to be protected by RCU Tasks Trace, and for such cases BPF link has to go through RCU Tasks Trace + "classic" RCU GPs before being deallocated. And so, if we put BPF program early, we might free BPF program before we free BPF link, leading to use-after-free situation. So, this patch defers bpf_prog_put() until we are ready to perform bpf_link's deallocation. At worst, this delays BPF program freeing by one extra RCU GP, but that seems completely acceptable. Alternatively, we'd need more elaborate ways to determine BPF hook, BPF link, and BPF program lifetimes, and how they relate to each other, which seems like an unnecessary complication. Note, for most BPF links we still will perform eager bpf_prog_put() and link dealloc, so for those BPF links there are no observable changes whatsoever. Only BPF links that use deferred dealloc might notice slightly delayed freeing of BPF programs. Also, to reduce code and logic duplication, extract program put + link dealloc logic into bpf_link_dealloc() helper.

There is a possible memory leak in lpfc_sli_brdrestart_s4() (restart) and lpfc_pci_remove_one_s4() (rmmod) paths because there are no calls to lpfc_sli4_queue_unset() to kfree() the wq->pring. Fix by inserting a call to lpfc_sli4_queue_unset() in lpfc_sli_brdrestart_s4() and lpfc_sli4_hba_unset() routines. Also, add a check for the SLI_ACTIVE flag before issuing the Q_DESTROY mailbox command. If not set, then the mailbox command will obviously fail. In such cases, skip issuing the mailbox command and only execute the driver resource clean up portions of the lpfc_*q_destroy routines.

If anyone has any objections, please let me know. ------------------ From: Esther Shimanovich <eshimanovich@chromium.org> [ Upstream commit 3b96b895127b7c0aed63d82c974b46340e8466c1 ] Some computers with CPUs that lack Thunderbolt features use discrete Thunderbolt chips to add Thunderbolt functionality. These Thunderbolt chips are located within the chassis; between the Root Port labeled ExternalFacingPort and the USB-C port. These Thunderbolt PCIe devices should be labeled as fixed and trusted, as they are built into the computer. Otherwise, security policies that rely on those flags may have unintended results, such as preventing USB-C ports from enumerating. Detect the above scenario through the process of elimination. 1) Integrated Thunderbolt host controllers already have Thunderbolt implemented, so anything outside their external facing Root Port is removable and untrusted. Detect them using the following properties: - Most integrated host controllers have the "usb4-host-interface" ACPI property, as described here: https://learn.microsoft.com/en-us/windows-hardware/drivers/pci/dsd-for-pcie-root-ports#mapping-native-protocols-pcie-displayport-tunneled-through-usb4-to-usb4-host-routers - Integrated Thunderbolt PCIe Root Ports before Alder Lake do not have the "usb4-host-interface" ACPI property. Identify those by their PCI IDs instead. 2) If a Root Port does not have integrated Thunderbolt capabilities, but has the "ExternalFacingPort" ACPI property, that means the manufacturer has opted to use a discrete Thunderbolt host controller that is built into the computer. This host controller can be identified by virtue of being located directly below an external-facing Root Port that lacks integrated Thunderbolt. Label it as trusted and fixed. Everything downstream from it is untrusted and removable. The "ExternalFacingPort" ACPI property is described here: https://learn.microsoft.com/en-us/windows-hardware/drivers/pci/dsd-for-pcie-root-ports#identifying-externally-exposed-pcie-root-ports Link: https://lore.kernel.org/r/20240910-trust-tbt-fix-v5-1-7a7a42a5f496@chromium.org Suggested-by: Mika Westerberg <mika.westerberg@linux.intel.com> Signed-off-by: Esther Shimanovich <eshimanovich@chromium.org> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Tested-by: Mika Westerberg <mika.westerberg@linux.intel.com> Tested-by: Mario Limonciello <mario.limonciello@amd.com> Reviewed-by: Mika Westerberg <mika.westerberg@linux.intel.com> Reviewed-by: Mario Limonciello <mario.limonciello@amd.com> Signed-off-by: Sasha Levin <sashal@kernel.org> --- arch/x86/pci/acpi.c | 119 ++++++++++++++++++++++++++++++++++++++++++++ drivers/pci/probe.c | 30 ++++++++--- include/linux/pci.h | 6 +++ 3 files changed, 148 insertions(+), 7 deletions(-) diff --git a/arch/x86/pci/acpi.c b/arch/x86/pci/acpi.c index ea2eb2ec90e2b..1e3bdefe9cb42 100644 --- a/arch/x86/pci/acpi.c +++ b/arch/x86/pci/acpi.c @@ -250,6 +250,125 @@ void __init pci_acpi_crs_quirks(void) pr_info("Please notify linux-pci@vger.kernel.org so future kernels can do this automatically\n"); } +/* + * Check if pdev is part of a PCIe switch that is directly below the + * specified bridge. + */ +static bool pcie_switch_directly_under(struct pci_dev *bridge, + struct pci_dev *pdev) +{ + struct pci_dev *parent = pci_upstream_bridge(pdev); + + /* If the device doesn't have a parent, it's not under anything */ + if (!parent) + return false; + + /* + * If the device has a PCIe type, check if it is below the + * corresponding PCIe switch components (if applicable).

These only work if the device is the only device below the bridge. Add a sysfs 'reset_subordinate' attribute on bridges that can assert Secondary Bus Reset regardless of how many devices are below the bridge. This resets all the devices below a bridge in a single command, including the locking and config space save/restore that reset methods normally do. This may be the only way to reset devices that don't support other reset methods (ACPI, FLR, PM reset, etc).

They may be multi-function devices, but they do not advertise an ACS capability. But the hardware does isolate FF5xxx functions as though it had an ACS capability and PCI_ACS_RR and PCI_ACS_CR were set in the ACS Control register, i.e., all peer-to-peer traffic is directed upstream instead of being routed internally.

Add quirks to skip ACPI I2C client enumeration and disable ACPI battery/AC and ACPI GPIO event handlers. Also add the "INT33F5" HID for the TI PMIC used on this tablet to the list of HIDs for which not to skip i2c_client instantiation, since we do want an ACPI instantiated i2c_client for the PMIC.

In other full device reset cases, that gets saved and restored during resume. v2: Remove redundant code like vcn_v4_0 did v2: Refine commit message v3: Drop the volatile v3: Refine commit message Signed-off-by: Xiang Liu <xiang.liu@amd.com> Acked-by: Christian König <christian.koenig@amd.com> Reviewed-by: Stanley.Yang <Stanley.Yang@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Sasha Levin <sashal@kernel.org> --- drivers/gpu/drm/amd/amdgpu/vcn_v4_0_3.c | 30 ++++++++++++++++++------- 1 file changed, 22 insertions(+), 8 deletions(-) diff --git a/drivers/gpu/drm/amd/amdgpu/vcn_v4_0_3.c b/drivers/gpu/drm/amd/amdgpu/vcn_v4_0_3.c index f85d18cd74eca..e80c4f5b4f402 100644 --- a/drivers/gpu/drm/amd/amdgpu/vcn_v4_0_3.c +++ b/drivers/gpu/drm/amd/amdgpu/vcn_v4_0_3.c @@ -77,6 +77,20 @@ static int vcn_v4_0_3_early_init(void *handle) return amdgpu_vcn_early_init(adev); } +static int vcn_v4_0_3_fw_shared_init(struct amdgpu_device *adev, int inst_idx) +{ + struct amdgpu_vcn4_fw_shared *fw_shared; + + fw_shared = adev->vcn.inst[inst_idx].fw_shared.cpu_addr; + fw_shared->present_flag_0 = cpu_to_le32(AMDGPU_FW_SHARED_FLAG_0_UNIFIED_QUEUE); + fw_shared->sq.is_enabled = 1; + + if (amdgpu_vcnfw_log) + amdgpu_vcn_fwlog_init(&adev->vcn.inst[inst_idx]); + + return 0; +} + /** * vcn_v4_0_3_sw_init - sw init for VCN block * @@ -107,8 +121,6 @@ static int vcn_v4_0_3_sw_init(void *handle) return r; for (i = 0; i < adev->vcn.num_vcn_inst; i++) { - volatile struct amdgpu_vcn4_fw_shared *fw_shared; - vcn_inst = GET_INST(VCN, i); ring = &adev->vcn.inst[i].ring_enc[0]; @@ -131,12 +143,7 @@ static int vcn_v4_0_3_sw_init(void *handle) if (r) return r; - fw_shared = adev->vcn.inst[i].fw_shared.cpu_addr; - fw_shared->present_flag_0 = cpu_to_le32(AMDGPU_FW_SHARED_FLAG_0_UNIFIED_QUEUE); - fw_shared->sq.is_enabled = true; - - if (amdgpu_vcnfw_log) - amdgpu_vcn_fwlog_init(&adev->vcn.inst[i]); + vcn_v4_0_3_fw_shared_init(adev, i); } if (amdgpu_sriov_vf(adev)) { @@ -221,6 +228,8 @@ static int vcn_v4_0_3_hw_init(void *handle) } } else { for (i = 0; i < adev->vcn.num_vcn_inst; ++i) { + struct amdgpu_vcn4_fw_shared *fw_shared; + vcn_inst = GET_INST(VCN, i); ring = &adev->vcn.inst[i].ring_enc[0]; @@ -244,6 +253,11 @@ static int vcn_v4_0_3_hw_init(void *handle) regVCN_RB1_DB_CTRL); } + /* Re-init fw_shared when RAS fatal error occurred */ + fw_shared = adev->vcn.inst[i].fw_shared.cpu_addr; + if (!fw_shared->sq.is_enabled) + vcn_v4_0_3_fw_shared_init(adev, i); + r = amdgpu_ring_test_helper(ring); if (r) goto done; -- 2.43.0 ^ permalink raw reply related [flat|nested] 370+ messages in thread

If anyone has any objections, please let me know. ------------------ From: Parker Newman <pnewman@connecttech.com> [ Upstream commit 7738a7ab9d12c5371ed97114ee2132d4512e9fd5 ] Add a quirk similar to eeprom_93xx46 to add an extra clock cycle before reading data from the EEPROM. The 93Cx6 family of EEPROMs output a "dummy 0 bit" between the writing of the op-code/address from the host to the EEPROM and the reading of the actual data from the EEPROM. More info can be found on page 6 of the AT93C46 datasheet (linked below). Similar notes are found in other 93xx6 datasheets. In summary the read operation for a 93Cx6 EEPROM is: Write to EEPROM: 110[A5-A0] (9 bits) Read from EEPROM: 0[D15-D0] (17 bits) Where: 110 is the start bit and READ OpCode [A5-A0] is the address to read from 0 is a "dummy bit" preceding the actual data [D15-D0] is the actual data. Looking at the READ timing diagrams in the 93Cx6 datasheets the dummy bit should be clocked out on the last address bit clock cycle meaning it should be discarded naturally. However, depending on the hardware configuration sometimes this dummy bit is not discarded. This is the case with Exar PCI UARTs which require an extra clock cycle between sending the address and reading the data.

(2) ->is_path_accessible() can't be called from cifs_tree_connect() as it would deadlock with smb2_reconnect(). This is required for checking if new DFS target is a nested DFS link. By unconditionally trying to get an DFS referral from new DFS target isn't correct because if the new DFS target (interlink) is an DFS standalone namespace, then we would end up getting -ELOOP and then potentially leaving tcon disconnected.

For some repositories and/or git versions, those 1.3s are actually 10-15 seconds. This has been acknowledged as a performance bug in git [1], and a fix is on its way [2]. However, no solution is yet in git.git, and even when one lands, it will take quite a while before it finds its way to a release and for $random_kernel_developer to pick that up. So rewrite the logic to use plumbing commands. For each of the candidate values of $tag, we ask: (1) is $tag even an annotated tag? (2) Is it eligible to describe HEAD, i.e. an ancestor of HEAD?

If anyone has any objections, please let me know. ------------------ From: Raghavendra K T <raghavendra.kt@amd.com> [ Upstream commit 84db47ca7146d7bd00eb5cf2b93989a971c84650 ] Since commit fc137c0ddab2 ("sched/numa: enhance vma scanning logic") NUMA Balancing allows updating PTEs to trap NUMA hinting faults if the task had previously accessed VMA. However unconditional scan of VMAs are allowed during initial phase of VMA creation until process's mm numa_scan_seq reaches 2 even though current task had not accessed VMA. Rationale: - Without initial scan subsequent PTE update may never happen. - Give fair opportunity to all the VMAs to be scanned and subsequently understand the access pattern of all the VMAs. But it has a corner case where, if a VMA is created after some time, process's mm numa_scan_seq could be already greater than 2. For e.g., values of mm numa_scan_seq when VMAs are created by running mmtest autonuma benchmark briefly looks like: start_seq=0 : 459 start_seq=2 : 138 start_seq=3 : 144 start_seq=4 : 8 start_seq=8 : 1 start_seq=9 : 1 This results in no unconditional PTE updates for those VMAs created after some time. Fix: - Note down the initial value of mm numa_scan_seq in per VMA start_seq. - Allow unconditional scan till start_seq + 2.

This issue can be consistently reproduced on three different servers: * a 448-core server * a 256-core server * a 192-core server [Root Cause] Since multiple threads are created by the hackbench program (along with the command argument 'thread'), a shared vma might be accessed by two or more cores simultaneously. When two or more cores observe that vma->numab_state is NULL at the same time, vma->numab_state will be overwritten. Although current code ensures that only one thread scans the VMAs in a single 'numa_scan_period', there might be a chance for another thread to enter in the next 'numa_scan_period' while we have not gotten till numab_state allocation [1]. Note that the command `/opt/ltp/testcases/bin/hackbench 50 process 1000` cannot the reproduce the issue. It is verified with 200+ test runs. [Solution] Use the cmpxchg atomic operation to ensure that only one thread executes the vma->numab_state assignment.

If anyone has any objections, please let me know. ------------------ From: Hugh Dickins <hughd@google.com> [ Upstream commit 1cb5d11a370f661c5d0d888bb0cfc2cdc5791382 ] "man 2 migrate_pages" says "On success migrate_pages() returns the number of pages that could not be moved". Although 5.3 and 5.4 commits fixed mbind(MPOL_MF_STRICT|MPOL_MF_MOVE*) to fail with EIO when not all pages could be moved (because some could not be isolated for migration), migrate_pages(2) was left still reporting only those pages failing at the migration stage, forgetting those failing at the earlier isolation stage. Fix that by accumulating a long nr_failed count in struct queue_pages, returned by queue_pages_range() when it's not returning an error, for adding on to the nr_failed count from migrate_pages() in mm/migrate.c. A count of pages? It's more a count of folios, but changing it to pages would entail more work (also in mm/migrate.c): does not seem justified. queue_pages_range() itself should only return -EIO in the "strictly unmovable" case (STRICT without any MOVEs): in that case it's best to break out as soon as nr_failed gets set; but otherwise it should continue to isolate pages for MOVing even when nr_failed - as the mbind(2) manpage promises. There's a case when nr_failed should be incremented when it was missed: queue_folios_pte_range() and queue_folios_hugetlb() count the transient migration entries, like queue_folios_pmd() already did. And there's a case when nr_failed should not be incremented when it would have been: in meeting later PTEs of the same large folio, which can only be isolated once: fixed by recording the current large folio in struct queue_pages. Clean up the affected functions, fixing or updating many comments. Bool migrate_folio_add(), without -EIO: true if adding, or if skipping shared (but its arguable folio_estimated_sharers() heuristic left unchanged). Use MPOL_MF_WRLOCK flag to queue_pages_range(), instead of bool lock_vma.

If anyone has any objections, please let me know. ------------------ From: David Hildenbrand <david@redhat.com> [ Upstream commit 091c1dd2d4df6edd1beebe0e5863d4034ade9572 ] We currently assume that there is at least one VMA in a MM, which isn't true. So we might end up having find_vma() return NULL, to then de-reference NULL. So properly handle find_vma() returning NULL.

If anyone has any objections, please let me know. ------------------ From: K Prateek Nayak <kprateek.nayak@amd.com> [ Upstream commit ea9cffc0a154124821531991d5afdd7e8b20d7aa ] The need_resched() check currently in nohz_csd_func() can be tracked to have been added in scheduler_ipi() back in 2011 via commit ca38062e57e9 ("sched: Use resched IPI to kick off the nohz idle balance") Since then, it has travelled quite a bit but it seems like an idle_cpu() check currently is sufficient to detect the need to bail out from an idle load balancing. To justify this removal, consider all the following case where an idle load balancing could race with a task wakeup: o Since commit f3dd3f674555b ("sched: Remove the limitation of WF_ON_CPU on wakelist if wakee cpu is idle") a target perceived to be idle (target_rq->nr_running == 0) will return true for ttwu_queue_cond(target) which will offload the task wakeup to the idle target via an IPI. In all such cases target_rq->ttwu_pending will be set to 1 before queuing the wake function. If an idle load balance races here, following scenarios are possible: - The CPU is not in TIF_POLLING_NRFLAG mode in which case an actual IPI is sent to the CPU to wake it out of idle. If the nohz_csd_func() queues before sched_ttwu_pending(), the idle load balance will bail out since idle_cpu(target) returns 0 since target_rq->ttwu_pending is 1. If the nohz_csd_func() is queued after sched_ttwu_pending() it should see rq->nr_running to be non-zero and bail out of idle load balancing. - The CPU is in TIF_POLLING_NRFLAG mode and instead of an actual IPI, the sender will simply set TIF_NEED_RESCHED for the target to put it out of idle and flush_smp_call_function_queue() in do_idle() will execute the call function. Depending on the ordering of the queuing of nohz_csd_func() and sched_ttwu_pending(), the idle_cpu() check in nohz_csd_func() should either see target_rq->ttwu_pending = 1 or target_rq->nr_running to be non-zero if there is a genuine task wakeup racing with the idle load balance kick. o The waker CPU perceives the target CPU to be busy (targer_rq->nr_running != 0) but the CPU is in fact going idle and due to a series of unfortunate events, the system reaches a case where the waker CPU decides to perform the wakeup by itself in ttwu_queue() on the target CPU but target is concurrently selected for idle load balance (XXX: Can this happen? I'm not sure, but we'll consider the mother of all coincidences to estimate the worst case scenario). ttwu_do_activate() calls enqueue_task() which would increment "rq->nr_running" post which it calls wakeup_preempt() which is responsible for setting TIF_NEED_RESCHED (via a resched IPI or by setting TIF_NEED_RESCHED on a TIF_POLLING_NRFLAG idle CPU) The key thing to note in this case is that rq->nr_running is already non-zero in case of a wakeup before TIF_NEED_RESCHED is set which would lead to idle_cpu() check returning false. In all cases, it seems that need_resched() check is unnecessary when checking for idle_cpu() first since an impending wakeup racing with idle load balancer will either set the "rq->ttwu_pending" or indicate a newly woken task via "rq->nr_running". Chasing the reason why this check might have existed in the first place, I came across Peter's suggestion on the fist iteration of Suresh's patch from 2011 [1] where the condition to raise the SCHED_SOFTIRQ was: sched_ttwu_do_pending(list); if (unlikely((rq->idle == current) && rq->nohz_balance_kick && !need_resched())) raise_softirq_irqoff(SCHED_SOFTIRQ); Since the condition to raise the SCHED_SOFIRQ was preceded by sched_ttwu_do_pending() (which is equivalent of sched_ttwu_pending()) in the current upstream kernel, the need_resched() check was necessary to catch a newly queued task. Peter suggested modifying it to: if (idle_cpu() && rq->nohz_balance_kick && !need_resched()) raise_softirq_irqoff(SCHED_SOFTIRQ); where idle_cpu() seems to have replaced "rq->idle == current" check. Even back then, the idle_cpu() check would have been sufficient to catch a new task being enqueued. Since commit b2a02fc43a1f ("smp: Optimize send_call_function_single_ipi()") overloads the interpretation of TIF_NEED_RESCHED for TIF_POLLING_NRFLAG idling, remove the need_resched() check in nohz_csd_func() to raise SCHED_SOFTIRQ based on Peter's suggestion.

A softirq raised by the call-function is handled shortly after in do_softirq_post_smp_call_flush() but the TIF_NEED_RESCHED flag remains set and is only cleared later when schedule_idle() calls __schedule(). need_resched() check in _nohz_idle_balance() exists to bail out of load balancing if another task has woken up on the CPU currently in-charge of idle load balancing which is being processed in SCHED_SOFTIRQ context. Since the optimization mentioned above overloads the interpretation of TIF_NEED_RESCHED, check for idle_cpu() before going with the existing need_resched() check which can catch a genuine task wakeup on an idle CPU processing SCHED_SOFTIRQ from do_softirq_post_smp_call_flush(), as well as the case where ksoftirqd needs to be preempted as a result of new task wakeup or slice expiry. In case of PREEMPT_RT or threadirqs, although the idle load balancing may be inhibited in some cases on the ilb CPU, the fact that ksoftirqd is the only fair task going back to sleep will trigger a newidle balance on the CPU which will alleviate some imbalance if it exists if idle balance fails to do so.

If the SMP function is invoked from an idle CPU via flush_smp_call_function_queue() then the HARD-IRQ flag is not set and raise_softirq_irqoff() needlessly wakes ksoftirqd because soft interrupts are handled before ksoftirqd get on the CPU. Adding a trace_printk() in nohz_csd_func() at the spot of raising SCHED_SOFTIRQ and enabling trace events for sched_switch, sched_wakeup, and softirq_entry (for SCHED_SOFTIRQ vector alone) helps observing the current behavior: <idle>-0 [000] dN.1.: nohz_csd_func: Raising SCHED_SOFTIRQ from nohz_csd_func <idle>-0 [000] dN.4.: sched_wakeup: comm=ksoftirqd/0 pid=16 prio=120 target_cpu=000 <idle>-0 [000] .Ns1.: softirq_entry: vec=7 [action=SCHED] <idle>-0 [000] .Ns1.: softirq_exit: vec=7 [action=SCHED] <idle>-0 [000] d..2.: sched_switch: prev_comm=swapper/0 prev_pid=0 prev_prio=120 prev_state=R ==> next_comm=ksoftirqd/0 next_pid=16 next_prio=120 ksoftirqd/0-16 [000] d..2.: sched_switch: prev_comm=ksoftirqd/0 prev_pid=16 prev_prio=120 prev_state=S ==> next_comm=swapper/0 next_pid=0 next_prio=120 ... Use __raise_softirq_irqoff() to raise the softirq. The SMP function call is always invoked on the requested CPU in an interrupt handler. It is guaranteed that soft interrupts are handled at the end. Following are the observations with the changes when enabling the same set of events: <idle>-0 [000] dN.1.: nohz_csd_func: Raising SCHED_SOFTIRQ for nohz_idle_balance <idle>-0 [000] dN.1.: softirq_raise: vec=7 [action=SCHED] <idle>-0 [000] .Ns1.: softirq_entry: vec=7 [action=SCHED] No unnecessary ksoftirqd wakeups are seen from idle task's context to service the softirq.

If anyone has any objections, please let me know. ------------------ From: Kir Kolyshkin <kolyshkin@gmail.com> [ Upstream commit d844fe65f0957024c3e1b0bf2a0615246184d9bc ] Both glibc and musl define 'struct sched_param' in sched.h, while kernel has it in uapi/linux/sched/types.h, making it cumbersome to use sched_getattr(2) or sched_setattr(2) from userspace. For example, something like this: #include <sched.h> #include <linux/sched/types.h> struct sched_attr sa; will result in "error: redefinition of ‘struct sched_param’" (note the code doesn't need sched_param at all -- it needs struct sched_attr plus some stuff from sched.h). The situation is, glibc is not going to provide a wrapper for sched_{get,set}attr, thus the need to include linux/sched_types.h directly, which leads to the above problem. Thus, the userspace is left with a few sub-par choices when it wants to use e.g. sched_setattr(2), such as maintaining a copy of struct sched_attr definition, or using some other ugly tricks. OTOH, 'struct sched_param' is well known, defined in POSIX, and it won't be ever changed (as that would break backward compatibility). So, while 'struct sched_param' is indeed part of the kernel uapi, exposing it the way it's done now creates an issue, and hiding it (like this patch does) fixes that issue, hopefully without creating another one: common userspace software rely on libc headers, and as for "special" software (like libc), it looks like glibc and musl do not rely on kernel headers for 'struct sched_param' definition (but let's Cc their mailing lists in case it's otherwise). The alternative to this patch would be to move struct sched_attr to, say, linux/sched.h, or linux/sched/attr.h (the new file). Oh, and here is the previous attempt to fix the issue: https://lore.kernel.org/all/20200528135552.GA87103@google.com/ While I support Linus arguments, the issue is still here and needs to be fixed. [ mingo: Linus is right, this shouldn't be needed - but on the other hand I agree that this header is not really helpful to user-space as-is. So let's pretend that <uapi/linux/sched/types.h> is only about sched_attr, and call this commit a workaround for user-space breakage that it in reality is ...

Tracing the absolute vruntime makes less sense, inconsistent: absolute-vs-delta, but also vruntime delta can be computed from runtime delta. Removing the vruntime thing also makes the two tracepoint sites identical, allowing to unify the code in a later patch.

It turns out that we can't do this, because while the old behavior of ignoring ignorable code points was most definitely wrong, we have case-folding filesystems with on-disk hash values with that wrong behavior. So now you can't look up those names, because they hash to something different. Of course, it's also entirely possible that in the meantime people have created *new* files with the new ("more correct") case folding logic, and reverting will just make other things break. The correct solution is to not do case folding in filesystems, but sadly, people seem to never really understand that. People still see it as a feature, not a bug.

If anyone has any objections, please let me know. ------------------ From: Yishai Hadas <yishaih@nvidia.com> [ Upstream commit 9c7c5430bca36e9636eabbba0b3b53251479c7ab ] Align the page tracking maximum message size with the device's capability instead of relying on PAGE_SIZE. This adjustment resolves a mismatch on systems where PAGE_SIZE is 64K, but the firmware only supports a maximum message size of 4K. Now that we rely on the device's capability for max_message_size, we must account for potential future increases in its value. Key considerations include: - Supporting message sizes that exceed a single system page (e.g., an 8K message on a 4K system). - Ensuring the RQ size is adjusted to accommodate at least 4 WQEs/messages, in line with the device specification. The above has been addressed as part of the patch.

But with "ENDBR64" instruction on x86, offset 4 is treated as function entry. So, X can't be 4 as well. Thus, 8 was used as offset for the test case. On 64-bit powerpc though, any offset <= 16 can be considered function entry depending on build configuration (see arch_kprobe_on_func_entry() for implementation details). So, use `vfs_read+20` to accommodate that scenario too.

If anyone has any objections, please let me know. ------------------ From: Nikolay Kuratov <kniv@yandex-team.ru> Since 5.16 and prior to 6.13 KVM can't be used with FSDAX guest memory (PMD pages). To reproduce the issue you need to reserve guest memory with `memmap=` cmdline, create and mount FS in DAX mode (tested both XFS and ext4), see doc link below. ndctl command for test: ndctl create-namespace -v -e namespace1.0 --map=dev --mode=fsdax -a 2M Then pass memory object to qemu like: -m 8G -object memory-backend-file,id=ram0,size=8G,\ mem-path=/mnt/pmem/guestmem,share=on,prealloc=on,dump=off,align=2097152 \ -numa node,memdev=ram0,cpus=0-1 QEMU fails to run guest with error: kvm run failed Bad address and there are two warnings in dmesg: WARN_ON_ONCE(!page_count(page)) in kvm_is_zone_device_page() and WARN_ON_ONCE(folio_ref_count(folio) <= 0) in try_grab_folio() (v6.6.63) It looks like in the past assumption was made that pfn won't change from faultin_pfn() to release_pfn_clean(), e.g. see commit 4cd071d13c5c ("KVM: x86/mmu: Move calls to thp_adjust() down a level") But kvm_page_fault structure made pfn part of mutable state, so now release_pfn_clean() can take hugepage-adjusted pfn. And it works for all cases (/dev/shm, hugetlb, devdax) except fsdax. Apparently in fsdax mode faultin-pfn and adjusted-pfn may refer to different folios, so we're getting get_page/put_page imbalance. To solve this preserve faultin pfn in separate local variable and pass it in kvm_release_pfn_clean(). Patch tested for all mentioned guest memory backends with tdp_mmu={0,1}. No bug in upstream as it was solved fundamentally by commit 8dd861cc07e2 ("KVM: x86/mmu: Put refcounted pages instead of blindly releasing pfns") and related patch series.

Patch series "mm/damon/vaddr: Fix issue in damon_va_evenly_split_region()". v2. According to the logic of damon_va_evenly_split_region(), currently following split case would not meet the expectation: Suppose DAMON_MIN_REGION=0x1000, Case: Split [0x0, 0x3000) into 2 pieces, then the result would be acutually 3 regions: [0x0, 0x1000), [0x1000, 0x2000), [0x2000, 0x3000) but NOT the expected 2 regions: [0x0, 0x1000), [0x1000, 0x3000) !!! The root cause is that when calculating size of each split piece in damon_va_evenly_split_region(): `sz_piece = ALIGN_DOWN(sz_orig / nr_pieces, DAMON_MIN_REGION);` both the dividing and the ALIGN_DOWN may cause loss of precision, then each time split one piece of size 'sz_piece' from origin 'start' to 'end' would cause more pieces are split out than expected!!! To fix it, count for each piece split and make sure no more than 'nr_pieces'. In addition, add above case into damon_test_split_evenly(). And add 'nr_piece == 1' check in damon_va_evenly_split_region() for better code readability and add a corresponding kunit testcase.

If anyone has any objections, please let me know. ------------------ From: Mathias Nyman <mathias.nyman@linux.intel.com> commit 9044ad57b60b0556d42b6f8aa218a68865e810a4 upstream. Don't flush all pending DbC data requests when an endpoint halts. An endpoint may halt and xHC DbC triggers a STALL error event if there's an issue with a bulk data transfer. The transfer should restart once xHC DbC receives a ClearFeature(ENDPOINT_HALT) request from the host. Once xHC DbC restarts it will start from the TRB pointed to by dequeue field in the endpoint context, which might be the same TRB we got the STALL event for. Turn the TRB to a no-op in this case to make sure xHC DbC doesn't reuse and tries to retransmit this same TRB after we already handled it, and gave its corresponding data request back. Other STALL events might be completely bogus. Lukasz Bartosik discovered that xHC DbC might issue spurious STALL events if hosts sends a ClearFeature(ENDPOINT_HALT) request to non-halted endpoints even without any active bulk transfers. Assume STALL event is spurious if it reports 0 bytes transferred, and the endpoint stopped on the STALLED TRB. Don't give back the data request corresponding to the TRB in this case. The halted status is per endpoint. Track it with a per endpoint flag instead of the driver invented DbC wide DS_STALLED state. DbC remains in DbC-Configured state even if endpoints halt. There is no Stalled state in the DbC Port state Machine (xhci section 7.6.6) Reported-by: Łukasz Bartosik <ukaszb@chromium.org> Closes: https://lore.kernel.org/linux-usb/20240725074857.623299-1-ukaszb@chromium.org/ Tested-by: Łukasz Bartosik <ukaszb@chromium.org> Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Link: https://lore.kernel.org/r/20240905143300.1959279-2-mathias.nyman@linux.intel.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> --- drivers/usb/host/xhci-dbgcap.c | 135 ++++++++++++++++++++++++----------------- drivers/usb/host/xhci-dbgcap.h | 2 2 files changed, 83 insertions(+), 54 deletions(-) --- a/drivers/usb/host/xhci-dbgcap.c +++ b/drivers/usb/host/xhci-dbgcap.c @@ -158,16 +158,18 @@ static void xhci_dbc_giveback(struct dbc spin_lock(&dbc->lock); } -static void xhci_dbc_flush_single_request(struct dbc_request *req) +static void trb_to_noop(union xhci_trb *trb) { - union xhci_trb *trb = req->trb; - trb->generic.field[0] = 0; trb->generic.field[1] = 0; trb->generic.field[2] = 0; trb->generic.field[3] &= cpu_to_le32(TRB_CYCLE); trb->generic.field[3] |= cpu_to_le32(TRB_TYPE(TRB_TR_NOOP)); +} +static void xhci_dbc_flush_single_request(struct dbc_request *req) +{ + trb_to_noop(req->trb); xhci_dbc_giveback(req, -ESHUTDOWN); } @@ -637,7 +639,6 @@ static void xhci_dbc_stop(struct xhci_db case DS_DISABLED: return; case DS_CONFIGURED: - case DS_STALLED: if (dbc->driver->disconnect) dbc->driver->disconnect(dbc); break; @@ -658,6 +659,23 @@ static void xhci_dbc_stop(struct xhci_db } static void +handle_ep_halt_changes(struct xhci_dbc *dbc, struct dbc_ep *dep, bool halted) +{ + if (halted) { + dev_info(dbc->dev, "DbC Endpoint halted\n"); + dep->halted = 1; + + } else if (dep->halted) { + dev_info(dbc->dev, "DbC Endpoint halt cleared\n"); + dep->halted = 0; + + if (!list_empty(&dep->list_pending)) + writel(DBC_DOOR_BELL_TARGET(dep->direction), + &dbc->regs->doorbell); + } +} + +static void dbc_handle_port_status(struct xhci_dbc *dbc, union xhci_trb *event) { u32 portsc; @@ -685,6 +703,7 @@ static void dbc_handle_xfer_event(struct struct xhci_ring *ring; int ep_id; int status; + struct xhci_ep_ctx *ep_ctx; u32 comp_code; size_t remain_length; struct dbc_request *req = NULL, *r; @@ -694,8 +713,30 @@ static void dbc_handle_xfer_event(struct ep_id = TRB_TO_EP_ID(le32_to_cpu(event->generic.field[3])); dep = (ep_id == EPID_OUT) ?

For example, if you run sensor buffer at 50Hz, stop, change to 200Hz, then back to 50Hz and restart buffer, data will be timestamped at 200Hz. This due to testing against mult and not new_mult. To prevent this, let's just run apply_odr automatically when FIFO is off. It will also simplify driver code. Update inv_mpu6050 and inv_icm42600 to delete now useless apply_odr.

There are reports that system cannot suspend due to running trim because the task responsible for trimming the device isn't able to finish in time, especially since we have a free extent discarding phase, which can trim a lot of unallocated space. There are no limits on the trim size (unlike the block group part). Since trime isn't a critical call it can be interrupted at any time, in such cases we stop the trim, report the amount of discarded bytes and return an error.

The correct logic should be that it only returns true when the GID is the same, and the SMC-D device is the same and the extended GID is the same (in the case of virtual ISM).
