XFRM state which is changed to be XFRM_STATE_EXPIRED doesn't really need to hold lock while modifying flow steering rules to drop traffic. That state can be deleted only and as such mlx5e_ipsec_handle_tx_limit() work will be canceled anyway and won't run in parallel.

2023-06-16net/mlx5e: Fix ESN update kernel panicPatrisious Haddad
Previously during mlx5e_ipsec_handle_event the driver tried to execute an operation that could sleep, while holding a spinlock, which caused the kernel panic mentioned below. Move the function call that can sleep outside of the spinlock context.

2023-06-16net/mlx5e: Don't delay release of hardware objectsLeon Romanovsky
XFRM core provides two callbacks to release resources, one is .xdo_dev_policy_delete() and another is .xdo_dev_policy_free(). This separation allows delayed release so "ip xfrm policy free" commands won't starve. Unfortunately, mlx5 command interface can't run in .xdo_dev_policy_free() callbacks as the latter runs in ATOMIC context.

2023-06-16net/mlx5: Free IRQ rmap and notifier on kernel shutdownSaeed Mahameed
The kernel IRQ system needs the irq affinity notifier to be clear before attempting to free the irq, see WARN_ON log below. On a normal driver unload we don't have this issue since we do the complete cleanup of the irq resources. To fix this, put the important resources cleanup in a helper function and use it in both normal driver unload and shutdown flows.

2023-06-16x86/mm: Avoid using set_pgd() outside of real PGD pagesLee Jones
KPTI keeps around two PGDs: one for userspace and another for the kernel. Among other things, set_pgd() contains infrastructure to ensure that updates to the kernel PGD are reflected in the user PGD as well. One side-effect of this is that set_pgd() expects to be passed whole pages. Unfortunately, init_trampoline_kaslr() passes in a single entry: 'trampoline_pgd_entry'. When KPTI is on, set_pgd() will update 'trampoline_pgd_entry' (an 8-Byte globally stored [.bss] variable) and will then proceed to replicate that value into the non-existent neighboring user page (located +4k away), leading to the corruption of other global [.bss] stored variables. Fix it by directly assigning 'trampoline_pgd_entry' and avoiding set_pgd().

2023-06-16tick/common: Align tick period during sched_timer setupThomas Gleixner
The tick period is aligned very early while the first clock_event_device is registered. At that point the system runs in periodic mode and switches later to one-shot mode if possible. The next wake-up event is programmed based on the aligned value (tick_next_period) but the delta value, that is used to program the clock_event_device, is computed based on ktime_get(). With the subtracted offset, the device fires earlier than the exact time frame. With a large enough offset the system programs the timer for the next wake-up and the remaining time left is too small to make any boot progress. The system hangs. Move the alignment later to the setup of tick_sched timer. At this point the system switches to oneshot mode and a high resolution clocksource is available.

2023-06-16x86/unwind/orc: Add ELF section with ORC version identifierOmar Sandoval
Commits ffb1b4a41016 ("x86/unwind/orc: Add 'signal' field to ORC metadata") and fb799447ae29 ("x86,objtool: Split UNWIND_HINT_EMPTY in two") changed the ORC format. Although ORC is internal to the kernel, it's the only way for external tools to get reliable kernel stack traces on x86-64. In particular, the drgn debugger [1] uses ORC for stack unwinding, and these format changes broke it [2]. As the drgn maintainer, I don't care how often or how much the kernel changes the ORC format as long as I have a way to detect the change. It suffices to store a version identifier in the vmlinux and kernel module ELF files (to use when parsing ORC sections from ELF), and in kernel memory (to use when parsing ORC from a core dump+symbol table). Rather than hard-coding a version number that needs to be manually bumped, Peterz suggested hashing the definitions from orc_types.h. If there is a format change that isn't caught by this, the hashing script can be updated. This patch adds an .orc_header allocated ELF section containing the 20-byte hash to vmlinux and kernel modules, along with the corresponding __start_orc_header and __stop_orc_header symbols in vmlinux. 1: https://github.com/osandov/drgn 2: https://github.com/osandov/drgn/issues/303 Fixes: ffb1b4a41016 ("x86/unwind/orc: Add 'signal' field to ORC metadata") Fixes: fb799447ae29 ("x86,objtool: Split UNWIND_HINT_EMPTY in two") Signed-off-by: Omar Sandoval <osandov@fb.com> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Acked-by: Josh Poimboeuf <jpoimboe@kernel.org> Link: https://lkml.kernel.org/r/aef9c8dc43915b886a8c48509a12ec1b006ca1ca.1686690801.git.osandov@osandov.com

2023-06-16perf/core: Drop __weak attribute from arch_perf_update_userpage() prototypeMarc Zyngier
Reiji reports that the arm64 implementation of arch_perf_update_userpage() is now ignored and replaced by the dummy stub in core code. This seems to happen since the PMUv3 driver was moved to driver/perf. As it turns out, dropping the __weak attribute from the *prototype* of the function solves the problem. You're right, this doesn't seem to make much sense. And yet... It appears that both symbols get flagged as weak, and that the first one to appear in the link order wins: $ nm drivers/perf/arm_pmuv3.o|grep arch_perf_update_userpage 0000000000001db0 W arch_perf_update_userpage Dropping the attribute from the prototype restores the expected behaviour, and arm64 is able to enjoy arch_perf_update_userpage() again.

2023-06-16xfrm: Linearize the skb after offloading if needed.Sebastian Andrzej Siewior
With offloading enabled, esp_xmit() gets invoked very late, from within validate_xmit_xfrm() which is after validate_xmit_skb() validates and linearizes the skb if the underlying device does not support fragments. esp_output_tail() may add a fragment to the skb while adding the auth tag/ IV. Devices without the proper support will then send skb->data points to with the correct length so the packet will have garbage at the end. A pcap sniffer will claim that the proper data has been sent since it parses the skb properly. It is not affected with INET_ESP_OFFLOAD disabled. Linearize the skb after offloading if the sending hardware requires it. It was tested on v4, v6 has been adopted.

2023-06-16ALSA: usb-audio: Add quirk flag for HEM devices to enable native DSD playbackLukasz Tyl
This commit adds new DEVICE_FLG with QUIRK_FLAG_DSD_RAW and Vendor Id for HEM devices which supports native DSD. Prior to this change Linux kernel was not enabling native DSD playback for HEM devices, and as a result, DSD audio was being converted to PCM "on the fly". HEM devices, when connected to the system, would only play audio in PCM format, even if the source material was in DSD format. With the addition of new VENDOR_FLG in the quircks.c file, the devices are now correctly recognized, and raw DSD data is transmitted to the device, allowing for native DSD playback.

2023-06-16ALSA: usb-audio: Fix broken resume due to UAC3 power stateTakashi Iwai
As reported in the bugzilla below, the PM resume of a UAC3 device may fail due to the incomplete power state change, stuck at D1. The reason is that the driver expects the full D0 power state change only at hw_params, while the normal PCM resume procedure doesn't call hw_params. For fixing the bug, we add the same power state update to D0 at the prepare callback, which is certainly called by the resume procedure. Note that, with this change, the power state change in the hw_params becomes almost redundant, since snd_usb_hw_params() doesn't touch the parameters (at least it tires so). But dropping it is still a bit risky (e.g. we have the media-driver binding), so I leave the D0 power state change in snd_usb_hw_params() as is for now.

Current release - regressions: - wifi: - cfg80211: fix double lock bug in reg_wdev_chan_valid() - iwlwifi: mvm: spin_lock_bh() to fix lockdep regression Current release - new code bugs: - handshake: remove fput() that causes use-after-free Previous releases - regressions: - sched: cls_u32: fix reference counter leak leading to overflow - sched: cls_api: fix lockup on flushing explicitly created chain Previous releases - always broken: - nf_tables: integrate pipapo into commit protocol - nf_tables: incorrect error path handling with NFT_MSG_NEWRULE, fix dangling pointer on failure - ping6: fix send to link-local addresses with VRF - sched: act_pedit: parse L3 header for L4 offset, the skb may not have the offset saved - sched: act_ct: fix promotion of offloaded unreplied tuple - sched: refuse to destroy an ingress and clsact Qdiscs if there are lockless change operations in flight - wifi: mac80211: fix handful of bugs in multi-link operation - ipvlan: fix bound dev checking for IPv6 l3s mode - eth: enetc: correct the indexes of highest and 2nd highest TCs - eth: ice: fix XDP memory leak when NIC is brought up and down Misc: - add deprecation notices for UDP-lite and DCCP - selftests: mptcp: skip tests not supported by old kernels - sctp: handle invalid error codes without calling BUG()" * tag 'net-6.4-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (91 commits) dccp: Print deprecation notice. udplite: Print deprecation notice. octeon_ep: Add missing check for ioremap selftests/ptp: Fix timestamp printf format for PTP_SYS_OFFSET net: ethernet: stmicro: stmmac: fix possible memory leak in __stmmac_open net: tipc: resize nlattr array to correct size sfc: fix XDP queues mode with legacy IRQ net: macsec: fix double free of percpu stats net: lapbether: only support ethernet devices MAINTAINERS: add reviewers for SMC Sockets s390/ism: Fix trying to free already-freed IRQ by repeated ism_dev_exit() net: dsa: felix: fix taprio guard band overflow at 10Mbps with jumbo frames net/sched: cls_api: Fix lockup on flushing explicitly created chain ice: Fix ice module unload net/handshake: remove fput() that causes use-after-free selftests: forwarding: hw_stats_l3: Set addrgenmode in a separate step net/sched: qdisc_destroy() old ingress and clsact Qdiscs before grafting net/sched: Refactor qdisc_graft() for ingress and clsact Qdiscs net/sched: act_ct: Fix promotion of offloaded unreplied tuple wifi: iwlwifi: mvm: spin_lock_bh() to fix lockdep regression ...

Pull rdma fixes from Jason Gunthorpe: "This is an unusually large bunch of bug fixes for the later rc cycle, rxe and mlx5 both dumped a lot of things at once. rxe continues to fix itself, and mlx5 is fixing a bunch of "queue counters" related bugs. There is one highly notable bug fix regarding the qkey. This small security check was missed in the original 2005 implementation and it allows some significant issues. Summary: - Two rtrs bug fixes for error unwind bugs - Several rxe bug fixes: * Incorrect Rx packet validation * Using memory without a refcount * Syzkaller found use before initialization * Regression fix for missing locking with the tasklet conversion from this merge window - Have bnxt report the correct link properties to userspace, this was a regression in v6.3 - Several mlx5 bug fixes: * Kernel crash triggerable by userspace for the RAW ethernet profile * Defend against steering refcounting issues created by userspace * Incorrect change of QP port affinity parameters in some LAG configurations - Fix mlx5 Q counters: * Do not over allocate Q counters to allow userspace to use the full port capacity * Kernel crash triggered by eswitch due to mis-use of Q counters * Incorrect mlx5_device for Q counters in some LAG configurations - Properly implement the IBA spec restricting privileged qkeys to root - Always an error when reading from a disassociated device's event queue - isert bug fixes: * Avoid a deadlock with the CM handler and CM ID destruction * Correct list corruption due to incorrect locking * Fix a use after free around connection tear down" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: RDMA/rxe: Fix rxe_cq_post IB/isert: Fix incorrect release of isert connection IB/isert: Fix possible list corruption in CMA handler IB/isert: Fix dead lock in ib_isert RDMA/mlx5: Fix affinity assignment IB/uverbs: Fix to consider event queue closing also upon non-blocking mode RDMA/uverbs: Restrict usage of privileged QKEYs RDMA/cma: Always set static rate to 0 for RoCE RDMA/mlx5: Fix Q-counters query in LAG mode RDMA/mlx5: Remove vport Q-counters dependency on normal Q-counters RDMA/mlx5: Fix Q-counters per vport allocation RDMA/mlx5: Create an indirect flow table for steering anchor RDMA/mlx5: Initiate dropless RQ for RAW Ethernet functions RDMA/rxe: Fix the use-before-initialization error of resp_pkts RDMA/bnxt_re: Fix reporting active_{speed,width} attributes RDMA/rxe: Fix ref count error in check_rkey() RDMA/rxe: Fix packet length checks RDMA/rtrs: Fix rxe_dealloc_pd warning RDMA/rtrs: Fix the last iu->buf leak in err path
