2024-11-05nvme-core: remove repeated wq flagsChaitanya Kulkarni
In nvme_core_init() nvme_wq, nvme_reset_wq, nvme_delete_wq share same flags :- WQ_UNBOUND | WQ_MEM_RECLAIM | WQ_SYSFS. Insated of repeating these flags in each call use the common variable.

2024-11-05nvmet: make nvmet_wq visible in sysfsGuixin Liu
In some complex scenarios, we deploy multiple tasks on a single machine (hybrid deployment), such as Docker containers for function computation (background processing), real-time tasks, monitoring, event handling, and management, along with an NVMe target server. Each of these components is restricted to its own CPU cores to prevent mutual interference and ensure strict isolation. To achieve this level of isolation for nvmet_wq we need to  use sysfs tunables such as cpumask that are currently not accessible. Add WQ_SYSFS flag to alloc_workqueue() when creating nvmet_wq so workqueue tunables are exported in the userspace via sysfs. with this patch :- nvme (nvme-6.13) # ls /sys/devices/virtual/workqueue/nvmet-wq/ affinity_scope  affinity_strict  cpumask  max_active  nice per_cpu power  subsystem  uevent Signed-off-by: Guixin Liu <kanie@linux.alibaba.com> Reviewed-by: Chaitanya Kulkarni <kch@nvidia.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Keith Busch <kbusch@kernel.org>
2024-11-05mm/slab: fix warning caused by duplicate kmem_cache creation in ↵Koichiro Den
kmem_buckets_create Commit b035f5a6d852 ("mm: slab: reduce the kmalloc() minimum alignment if DMA bouncing possible") reduced ARCH_KMALLOC_MINALIGN to 8 on arm64. However, with KASAN_HW_TAGS enabled, arch_slab_minalign() becomes 16. This causes kmalloc_caches[*][8] to be aliased to kmalloc_caches[*][16], resulting in kmem_buckets_create() attempting to create a kmem_cache for size 16 twice.

The HMB descriptor table is sized to the maximum number of descriptors that could be used for a given device, but __nvme_alloc_host_mem could break out of the loop earlier on memory allocation failure and end up using less descriptors than planned for, which leads to an incorrect size passed to dma_free_coherent. In practice this was not showing up because the number of descriptors tends to be low and the dma coherent allocator always allocates and frees at least a page.

This issue is not present on AM62 as separate pair of rings are used for free and completion rings for each flow. Fix this by allocating enough elements for RX free descriptor ring 0. However, we can no longer rely on desc_idx (descriptor based offsets) to identify the pages in the respective flows as free descriptor ring includes elements for all flows. To solve this, introduce a new swdata data structure to store flow_id and page. This can be used to identify which flow (page_pool) and page the descriptor belonged to when popped out of the RX rings.

2024-11-05thunderbolt: Fix connection issue with Pluggable UD-4VPD dockMika Westerberg
Rick reported that his Pluggable USB4 dock does not work anymore after upgrading to v6.10 kernel. It looks like commit c6ca1ac9f472 ("thunderbolt: Increase sideband access polling delay") makes the device router enumeration happen later than what might be expected by the dock (although there is no such limit in the USB4 spec) which probably makes it assume there is something wrong with the high-speed link and reset it. After the link is reset the same issue happens again and again. For this reason lower the sideband access delay from 5ms to 1ms. This seems to work fine according to Rick's testing.

2024-11-05arm64: Add support for FEAT_HAFTYicong Yang
Armv8.9/v9.4 introduces the feature Hardware managed Access Flag for Table descriptors (FEAT_HAFT). The feature is indicated by ID_AA64MMFR1_EL1.HAFDBS == 0b0011 and can be enabled by TCR2_EL1.HAFT so it has a dependency on FEAT_TCR2. Adds the Kconfig for FEAT_HAFT and support detecting and enabling the feature. The feature is enabled in __cpu_setup() before MMU on just like HA. A CPU capability is added to notify the user of the feature. Add definition of P{G,4,U,M}D_TABLE_AF bit and set the AF bit when creating the page table, which will save the hardware from having to update them at runtime. This will be ignored if FEAT_HAFT is not enabled. The AF bit of table descriptors cannot be managed by the software per spec, unlike the HA. So this should be used only if it's supported system wide by system_supports_haft().

2024-11-04KVM: nVMX: Treat vpid01 as current if L2 is active, but with VPID disabledSean Christopherson
When getting the current VPID, e.g. to emulate a guest TLB flush, return vpid01 if L2 is running but with VPID disabled, i.e. if VPID is disabled in vmcs12. Architecturally, if VPID is disabled, then the guest and host effectively share VPID=0. KVM emulates this behavior by using vpid01 when running an L2 with VPID disabled (see prepare_vmcs02_early_rare()), and so KVM must also treat vpid01 as the current VPID while L2 is active. Unconditionally treating vpid02 as the current VPID when L2 is active causes KVM to flush TLB entries for vpid02 instead of vpid01, which results in TLB entries from L1 being incorrectly preserved across nested VM-Enter to L2 (L2=>L1 isn't problematic, because the TLB flush after nested VM-Exit flushes vpid01). The bug manifests as failures in the vmx_apicv_test KVM-Unit-Test, as KVM incorrectly retains TLB entries for the APIC-access page across a nested VM-Enter. Opportunisticaly add comments at various touchpoints to explain the architectural requirements, and also why KVM uses vpid01 instead of vpid02.

2024-11-04KVM: selftests: Disable strict aliasingSean Christopherson
Disable strict aliasing, as has been done in the kernel proper for decades (literally since before git history) to fix issues where gcc will optimize away loads in code that looks 100% correct, but is _technically_ undefined behavior, and thus can be thrown away by the compiler. E.g. arm64's vPMU counter access test casts a uint64_t (unsigned long) pointer to a u64 (unsigned long long) pointer when setting PMCR.N via u64p_replace_bits(), which gcc-13 detects and optimizes away, i.e. ignores the result and uses the original PMCR. The issue is most easily observed by making set_pmcr_n() noinline and wrapping the call with printf(), e.g. sans comments, for this code: printf("orig = %lx, next = %lx, want = %lu\n", pmcr_orig, pmcr, pmcr_n); set_pmcr_n(&pmcr, pmcr_n); printf("orig = %lx, next = %lx, want = %lu\n", pmcr_orig, pmcr, pmcr_n); gcc-13 generates: 0000000000401c90 <set_pmcr_n>: 401c90: f9400002 ldr x2, [x0] 401c94: b3751022 bfi x2, x1, #11, #5 401c98: f9000002 str x2, [x0] 401c9c: d65f03c0 ret 0000000000402660 <test_create_vpmu_vm_with_pmcr_n>: 402724: aa1403e3 mov x3, x20 402728: aa1503e2 mov x2, x21 40272c: aa1603e0 mov x0, x22 402730: aa1503e1 mov x1, x21 402734: 940060ff bl 41ab30 <_IO_printf> 402738: aa1403e1 mov x1, x20 40273c: 910183e0 add x0, sp, #0x60 402740: 97fffd54 bl 401c90 <set_pmcr_n> 402744: aa1403e3 mov x3, x20 402748: aa1503e2 mov x2, x21 40274c: aa1503e1 mov x1, x21 402750: aa1603e0 mov x0, x22 402754: 940060f7 bl 41ab30 <_IO_printf> with the value stored in [sp + 0x60] ignored by both printf() above and in the test proper, resulting in a false failure due to vcpu_set_reg() simply storing the original value, not the intended value. $ ./vpmu_counter_access Random seed: 0x6b8b4567 orig = 3040, next = 3040, want = 0 orig = 3040, next = 3040, want = 0 ==== Test Assertion Failure ==== aarch64/vpmu_counter_access.c:505: pmcr_n == get_pmcr_n(pmcr) pid=71578 tid=71578 errno=9 - Bad file descriptor 1 0x400673: run_access_test at vpmu_counter_access.c:522 2 (inlined by) main at vpmu_counter_access.c:643 3 0x4132d7: __libc_start_call_main at libc-start.o:0 4 0x413653: __libc_start_main at ??:0 5 0x40106f: _start at ??:0 Failed to update PMCR.N to 0 (received: 6) Somewhat bizarrely, gcc-11 also exhibits the same behavior, but only if set_pmcr_n() is marked noinline, whereas gcc-13 fails even if set_pmcr_n() is inlined in its sole caller.

When memslot_perf_test is run nested, first iteration of test_memslot_rw_loop testcase, sometimes takes more than 2 seconds due to build of shadow page tables. Following iterations are fast. To be on the safe side, bump the timeout to 10 seconds.

2024-11-04scsi: ufs: core: Start the RTC update work laterBart Van Assche
The RTC update work involves runtime resuming the UFS controller. Hence, only start the RTC update work after runtime power management in the UFS driver has been fully initialized. This patch fixes the following kernel crash: Internal error: Oops: 0000000096000006 [#1] PREEMPT SMP Workqueue: events ufshcd_rtc_work Call trace: _raw_spin_lock_irqsave+0x34/0x8c (P) pm_runtime_get_if_active+0x24/0x9c (L) pm_runtime_get_if_active+0x24/0x9c ufshcd_rtc_work+0x138/0x1b4 process_one_work+0x148/0x288 worker_thread+0x2cc/0x3d4 kthread+0x110/0x114 ret_from_fork+0x10/0x20 Reported-by: Neil Armstrong <neil.armstrong@linaro.org> Closes: https://lore.kernel.org/linux-scsi/0c0bc528-fdc2-4106-bc99-f23ae377f6f5@linaro.org/ Fixes: 6bf999e0eb41 ("scsi: ufs: core: Add UFS RTC support") Cc: Bean Huo <beanhuo@micron.com> Cc: stable@vger.kernel.org Signed-off-by: Bart Van Assche <bvanassche@acm.org> Link: https://lore.kernel.org/r/20241031212632.2799127-1-bvanassche@acm.org Reviewed-by: Peter Wang <peter.wang@mediatek.com> Reviewed-by: Bean Huo <beanhuo@micron.com> Tested-by: Neil Armstrong <neil.armstrong@linaro.org> # on SM8650-HDK Signed-off-by: Martin K.

git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can Marc Kleine-Budde says: ==================== pull-request: can 2024-11-04 Alexander Hölzl contributes a patch to fix an error in the CAN j1939 documentation. Thomas Mühlbacher's patch allows building of the {cc770,sja1000}_isa drivers on x86_64 again. A patch by me targets the m_can driver and limits the call to free_irq() to devices with IRQs. Dario Binacchi's patch fixes the RX and TX error counters in the c_can driver. The next 2 patches target the rockchip_canfd driver. Geert Uytterhoeven's patch lets the driver depend on ARCH_ROCKCHIP. Jean Delvare's patch drops the obsolete dependency on COMPILE_TEST. The last 2 patches are by me and fix 2 regressions in the mcp251xfd driver: fix broken coalescing configuration when switching CAN modes and fix the length calculation of the Transmit Event FIFO (TEF) on full TEF. * tag 'linux-can-fixes-for-6.12-20241104' of git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can: can: mcp251xfd: mcp251xfd_get_tef_len(): fix length calculation can: mcp251xfd: mcp251xfd_ring_alloc(): fix coalescing configuration when switching CAN modes can: rockchip_canfd: Drop obsolete dependency on COMPILE_TEST can: rockchip_canfd: CAN_ROCKCHIP_CANFD should depend on ARCH_ROCKCHIP can: c_can: fix {rx,tx}_errors statistics can: m_can: m_can_close(): don't call free_irq() for IRQ-less devices can: {cc770,sja1000}_isa: allow building on x86_64 can: j1939: fix error in J1939 documentation. ==================== Link: https://patch.msgid.link/20241104200120.393312-1-mkl@pengutronix.de Signed-off-by: Jakub Kicinski <kuba@kernel.org>
