2024-08-30io_uring/kbuf: return correct iovec count from classic buffer peekJens Axboe
io_provided_buffers_select() returns 0 to indicate success, but it should be returning 1 to indicate that 1 vec was mapped. This causes peeking to fail with classic provided buffers, and while that's not a use case that anyone should use, it should still work correctly. The end result is that no buffer will be selected, and hence a completion with '0' as the result will be posted, without a buffer attached.

2024-08-30nfsd: fix nfsd4_deleg_getattr_conflict in presence of third party leaseNeilBrown
It is not safe to dereference fl->c.flc_owner without first confirming fl->fl_lmops is the expected manager. nfsd4_deleg_getattr_conflict() tests fl_lmops but largely ignores the result and assumes that flc_owner is an nfs4_delegation anyway. This is wrong. With this patch we restore the "!= &nfsd_lease_mng_ops" case to behave as it did before the change mentioned below. This is the same as the current code, but without any reference to a possible delegation.

2024-08-30igc: Get rid of spurious interruptsKurt Kanzenbach
When running the igc with XDP/ZC in busy polling mode with deferral of hard interrupts, interrupts still happen from time to time. That is caused by the igc task watchdog which triggers Rx interrupts periodically. That mechanism has been introduced to overcome skb/memory allocation failures [1]. So the Rx clean functions stop processing the Rx ring in case of such failure. The task watchdog triggers Rx interrupts periodically in the hope that memory became available in the mean time. The current behavior is undesirable for real time applications, because the driver induced Rx interrupts trigger also the softirq processing. However, all real time packets should be processed by the application which uses the busy polling method. Therefore, only trigger the Rx interrupts in case of real allocation failures. Introduce a new flag for signaling that condition.

2024-08-30igc: Add MQPRIO offload supportKurt Kanzenbach
Add support for offloading MQPRIO. The hardware has four priorities as well as four queues. Each queue must be a assigned with a unique priority. However, the priorities are only considered in TSN Tx mode. There are two TSN Tx modes. In case of MQPRIO the Qbv capability is not required. Therefore, use the legacy TSN Tx mode, which performs strict priority arbitration. Example for mqprio with hardware offload: |tc qdisc replace dev ${INTERFACE} handle 100 parent root mqprio num_tc 4 \ | map 0 0 0 0 0 1 2 3 0 0 0 0 0 0 0 0 \ | queues 1@0 1@1 1@2 1@3 \ | hw 1 The mqprio Qdisc also allows to configure the `preemptible_tcs'. However, frame preemption is not supported yet. Tested on Intel i225 and implemented by following data sheet section 7.5.2, Transmit Scheduling.

2024-08-30io_uring/rsrc: ensure compat iovecs are copied correctlyJens Axboe
For buffer registration (or updates), a userspace iovec is copied in and updated. If the application is within a compat syscall, then the iovec type is compat_iovec rather than iovec. However, the type used in __io_sqe_buffers_update() and io_sqe_buffers_register() is always struct iovec, and hence the source is incremented by the size of a non-compat iovec in the loop. This misses every other iovec in the source, and will run into garbage half way through the copies and return -EFAULT to the application. Maintain the source address separately and assign to our user vec pointer, so that copies always happen from the right source address. While in there, correct a bad placement of __user which triggered the following sparse warning prior to this fix: io_uring/rsrc.c:981:33: warning: cast removes address space '__user' of expression io_uring/rsrc.c:981:30: warning: incorrect type in assignment (different address spaces) io_uring/rsrc.c:981:30: expected struct iovec const [noderef] __user *uvec io_uring/rsrc.c:981:30: got struct iovec *[noderef] __user Fixes: f4eaf8eda89e ("io_uring/rsrc: Drop io_copy_iov in favor of iovec API") Reviewed-by: Gabriel Krisman Bertazi <krisman@suse.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>

The latter clears the invalidated bit of a partial pages rather than discarding it entirely. This causes copy_file_range() to fail on cifs because the partial pages at either end of the destination range aren't evicted and reread, but rather just partly cleared.

2024-08-30drm: komeda: Fix an issue related to normalized zposhongchi.peng
We use komeda_crtc_normalize_zpos to normalize zpos of affected planes to their blending zorder in CU. If there's only one slave plane in affected planes and its layer_split property is enabled, order++ for its split layer, so that when calculating the normalized_zpos of master planes, the split layer of the slave plane is included, but the max_slave_zorder does not include the split layer and keep zero because there's only one slave plane in affacted planes, although we actually use two slave layers in this commit. In most cases, this bug does not result in a commit failure, but assume the following situation: slave_layer 0: zpos = 0, layer split enabled, normalized_zpos = 0;(use slave_layer 2 as its split layer) master_layer 0: zpos = 2, layer_split enabled, normalized_zpos = 2;(use master_layer 2 as its split layer) master_layer 1: zpos = 4, normalized_zpos = 4; master_layer 3: zpos = 5, normalized_zpos = 5; kcrtc_st->max_slave_zorder = 0; When we use master_layer 3 as a input of CU in function komeda_compiz_set_input and check it with function komeda_component_check_input, the parameter idx is equal to normailzed_zpos minus max_slave_zorder, the value of idx is 5 and is euqal to CU's max_active_inputs, so that komeda_component_check_input returns a -EINVAL value. To fix the bug described above, when calculating the max_slave_zorder with the layer_split enabled, count the split layer in this calculation directly.

2024-08-30net/smc: prevent NULL pointer dereference in txopt_getJeongjun Park
Since smc_inet6_prot does not initialize ipv6_pinfo_offset, inet6_create() copies an incorrect address value, sk + 0 (offset), to inet_sk(sk)->pinet6. In addition, since inet_sk(sk)->pinet6 and smc_sk(sk)->clcsock practically point to the same address, when smc_create_clcsk() stores the newly created clcsock in smc_sk(sk)->clcsock, inet_sk(sk)->pinet6 is corrupted into clcsock. This causes NULL pointer dereference and various other memory corruptions. To solve this problem, you need to initialize ipv6_pinfo_offset, add a smc6_sock structure, and then add ipv6_pinfo as the second member of the smc_sock structure.

In case of error in build_tokens_sysfs(), all the memory that has been allocated is freed at end of this function. But then free_group() is called which performs memory deallocation again. Also, instead of free_group() call, there should be exit_dell_smbios_smm() and exit_dell_smbios_wmi() calls, since there is initialization, but there is no release of resources in case of an error.

2024-08-30dcache: keep dentry_hashtable or d_hash_shift even when not usedStephen Brennan
The runtime constant feature removes all the users of these variables, allowing the compiler to optimize them away. It's quite difficult to extract their values from the kernel text, and the memory saved by removing them is tiny, and it was never the point of this optimization. Since the dentry_hashtable is a core data structure, it's valuable for debugging tools to be able to read it easily. For instance, scripts built on drgn, like the dentrycache script[1], rely on it to be able to perform diagnostics on the contents of the dcache. Annotate it as used, so the compiler doesn't discard it.

Michael Chan says: ==================== bnxt_en: Update for net-next This series starts with 2 patches to support firmware crash dump. The driver allocates the required DMA memory ahead of time for firmware to store the crash dump if and when it crashes. Patch 3 adds priority and TPID for the .ndo_set_vf_vlan() callback. Note that this was rejected and reverted last year and it is being re-submitted after recent changes in the guidelines. The remaining patches are MSIX related. Legacy interrupt is no longer supported by firmware so we remove the support in the driver. We then convert to use the newer kernel APIs to allocate and enable MSIX vectors.

2024-08-29bnxt_en: Support dynamic MSIXMichael Chan
A range of MSIX vectors are allocated at initialization for the number needed for RocE and L2. During run-time, if the user increases or decreases the number of L2 rings, all the MSIX vectors have to be freed and a new range has to be allocated. This is not optimal and causes disruptions to RoCE traffic every time there is a change in L2 MSIX. If the system supports dynamic MSIX allocations, use dynamic allocation to add new L2 MSIX vectors or free unneeded L2 MSIX vectors. RoCE traffic is not affected using this scheme.

2024-08-29MAINTAINERS: exclude bluetooth and wireless DT bindings from netdev MLJakub Kicinski
We exclude wireless drivers from the netdev@ traffic, to delegate it to linux-wireless@, and avoid overwhelming netdev@. Bluetooth drivers are implicitly excluded because they live under drivers/bluetooth, not drivers/net. In both cases DT bindings sit under Documentation/devicetree/bindings/net/ and aren't excluded. So if a patch series touches DT bindings netdev@ ends up getting CCed, and these are usually fairly boring series.

2024-08-29tools: ynl: error check scanf() in a sampleJakub Kicinski
Someone reported on GitHub that the YNL NIPA test is failing when run locally. The test builds the tools, and it hits: netdev.c:82:9: warning: ignoring return value of ‘scanf’ declared with attribute ‘warn_unused_result’ [-Wunused-result] 82 | scanf("%d", &ifindex); I can't repro this on my setups but error seems clear enough.

2024-08-29Merge branch 'replace-deprecated-strcpy-with-strscpy'Jakub Kicinski
Hongbo Li says: ==================== replace deprecated strcpy with strscpy The deprecated helper strcpy() performs no bounds checking on the destination buffer. This could result in linear overflows beyond the end of the buffer, leading to all kinds of misbehaviors. The safe replacement is strscpy() [1].
