git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fix from Steven Rostedt: "Fix showing of TASK_COMM_LEN instead of its value The TASK_COMM_LEN was converted from a macro into an enum so that BTF would have access to it. But this unfortunately caused TASK_COMM_LEN to display in the format fields of trace events, as they are created by the TRACE_EVENT() macro and such, macros convert to their values, where as enums do not. To handle this, instead of using the field itself to be display, save the value of the array size as another field in the trace_event_fields structure, and use that instead. Not only does this fix the issue, but also converts the other trace events that have this same problem (but were not breaking tooling). With this change, the original work around b3bc8547d3be6 ("tracing: Have TRACE_DEFINE_ENUM affect trace event types as well") could be reverted (but that should be done in the merge window)" * tag 'trace-v6.2-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing: Fix TASK_COMM_LEN in trace event format file

So even if we came in with compound page, the page can already be freed and PageHead can return false and we will end up freeing all the tail pages causing double free.

2023-02-12tracing: Fix TASK_COMM_LEN in trace event format fileYafang Shao
After commit 3087c61ed2c4 ("tools/testing/selftests/bpf: replace open-coded 16 with TASK_COMM_LEN"), the content of the format file under /sys/kernel/tracing/events/task/task_newtask was changed from field:char comm[16]; offset:12; size:16; signed:0; to field:char comm[TASK_COMM_LEN]; offset:12; size:16; signed:0; John reported that this change breaks older versions of perfetto. Then Mathieu pointed out that this behavioral change was caused by the use of __stringify(_len), which happens to work on macros, but not on enum labels. And he also gave the suggestion on how to fix it: :One possible solution to make this more robust would be to extend :struct trace_event_fields with one more field that indicates the length :of an array as an actual integer, without storing it in its stringified :form in the type, and do the formatting in f_show where it belongs.

2023-02-11perf/x86/intel/uncore: Add Meteor Lake supportKan Liang
The uncore subsystem for Meteor Lake is similar to the previous Alder Lake. The main difference is that MTL provides PMU support for different tiles, while ADL only provides PMU support for the whole package. On ADL, there are CBOX, ARB, and clockbox uncore PMON units. On MTL, they are split into CBOX/HAC_CBOX, ARB/HAC_ARB, and cncu/sncu which provides a fixed counter for clockticks. Also, new MSR addresses are introduced on MTL. The IMC uncore PMON is the same as Alder Lake. Add new PCIIDs of IMC for Meteor Lake.

2023-02-11perf/x86/intel/ds: Fix the conversion from TSC to perf timeKan Liang
The time order is incorrect when the TSC in a PEBS record is used. $perf record -e cycles:upp dd if=/dev/zero of=/dev/null count=10000 $ perf script --show-task-events perf-exec 0 0.000000: PERF_RECORD_COMM: perf-exec:915/915 dd 915 106.479872: PERF_RECORD_COMM exec: dd:915/915 dd 915 106.483270: PERF_RECORD_EXIT(915:915):(914:914) dd 915 106.512429: 1 cycles:upp: ffffffff96c011b7 [unknown] ([unknown]) ... ... The perf time is from sched_clock_cpu(). The current PEBS code unconditionally convert the TSC to native_sched_clock(). There is a shift between the two clocks. If the TSC is stable, the shift is consistent, __sched_clock_offset. If the TSC is unstable, the shift has to be calculated at runtime. This patch doesn't support the conversion when the TSC is unstable. The TSC unstable case is a corner case and very unlikely to happen. If it happens, the TSC in a PEBS record will be dropped and fall back to perf_event_clock().

2023-02-11sched/deadline: Add more reschedule cases to prio_changed_dl()Valentin Schneider
I've been tracking down an issue on a ~5.17ish kernel where: CPUx CPUy <DL task p0 owns an rtmutex M> <p0 depletes its runtime, gets throttled> <rq switches to the idle task> <DL task p1 blocks on M, boost/replenish p0> <No call to resched_curr() happens here> [idle task keeps running here until *something* accidentally sets TIF_NEED_RESCHED] On that kernel, it is quite easy to trigger using rt-tests's deadline_test [1] with the test running on isolated CPUs (this reduces the chance of something unrelated setting TIF_NEED_RESCHED on the idle tasks, making the issue even more obvious as the hung task detector chimes in). I haven't been able to reproduce this using a mainline kernel, even if I revert 2972e3050e35 ("tracing: Make trace_marker{,_raw} stream-like") which gets rid of the lock involved in the above test, *but* I cannot convince myself the issue isn't there from looking at the code. Make prio_changed_dl() issue a reschedule if the current task isn't a deadline one. While at it, ensure a reschedule is emitted when a queued-but-not-current task gets boosted with an earlier deadline that current's.

2023-02-11sched/fair: sanitize vruntime of entity being placedZhang Qiao
When a scheduling entity is placed onto cfs_rq, its vruntime is pulled to the base level (around cfs_rq->min_vruntime), so that the entity doesn't gain extra boost when placed backwards. However, if the entity being placed wasn't executed for a long time, its vruntime may get too far behind (e.g. while cfs_rq was executing a low-weight hog), which can inverse the vruntime comparison due to s64 overflow. This results in the entity being placed with its original vruntime way forwards, so that it will effectively never get to the cpu. To prevent that, ignore the vruntime of the entity being placed if it didn't execute for much longer than the characteristic sheduler time scale.

2023-02-11sched/fair: unlink misfit task from cpu overutilizedVincent Guittot
By taking into account uclamp_min, the 1:1 relation between task misfit and cpu overutilized is no more true as a task with a small util_avg may not fit a high capacity cpu because of uclamp_min constraint. Add a new state in util_fits_cpu() to reflect the case that task would fit a CPU except for the uclamp_min hint which is a performance requirement. Use -1 to reflect that a CPU doesn't fit only because of uclamp_min so we can use this new value to take additional action to select the best CPU that doesn't match uclamp_min hint. When util_fits_cpu() returns -1, we will continue to look for a possible CPU with better performance, which replaces Capacity Inversion detection with capacity_orig_of() - thermal_load_avg to detect a capacity inversion.

2023-02-11ALSA: hda: Fix codec device field initializanCezary Rojewski
Commit f2bd1c5ae2cb ("ALSA: hda: Fix page fault in snd_hda_codec_shutdown()") relocated initialization of several codec device fields. Due to differences between codec_exec_verb() and snd_hdac_bus_exec_bus() in how they handle VERB execution - the latter does not touch PM - assigning ->exec_verb to codec_exec_verb() causes PM to be engaged before it is configured for the device. Configuration of PM for the ASoC HDAudio sound card is done with snd_hda_set_power_save() during skl_hda_audio_probe() whereas the assignment happens early, in snd_hda_codec_device_init(). Revert to previous behavior to avoid problems caused by too early PM manipulation.

2023-02-10net: Remove WARN_ON_ONCE(sk->sk_forward_alloc) from sk_stream_kill_queues().Kuniyuki Iwashima
Christoph Paasch reported that commit b5fc29233d28 ("inet6: Remove inet6_destroy_sock() in sk->sk_prot->destroy().") started triggering WARN_ON_ONCE(sk->sk_forward_alloc) in sk_stream_kill_queues(). [0 - 2] Also, we can reproduce it by a program in [3]. In the commit, we delay freeing ipv6_pinfo.pktoptions from sk->destroy() to sk->sk_destruct(), so sk->sk_forward_alloc is no longer zero in inet_csk_destroy_sock(). The same check has been in inet_sock_destruct() from at least v2.6, we can just remove the WARN_ON_ONCE(). However, among the users of sk_stream_kill_queues(), only CAIF is not calling inet_sock_destruct(). Thus, we add the same WARN_ON_ONCE() to caif_sock_destructor().

Eric Dumazet pointed out [0] that when we call skb_set_owner_r() for ipv6_pinfo.pktoptions, sk_rmem_schedule() has not been called, resulting in a negative sk_forward_alloc. We add a new helper which clones a skb and sets its owner only when sk_rmem_schedule() succeeds. Note that we move skb_set_owner_r() forward in (dccp|tcp)_v6_do_rcv() because tcp_send_synack() can make sk_forward_alloc negative before ipv6_opt_accepted() in the crossed SYN-ACK or self-connect() cases.

2023-02-10net: ethernet: ti: am65-cpsw: Add RX DMA Channel Teardown QuirkSiddharth Vadapalli
In TI's AM62x/AM64x SoCs, successful teardown of RX DMA Channel raises an interrupt. The process of servicing this interrupt involves flushing all pending RX DMA descriptors and clearing the teardown completion marker (TDCM). The am65_cpsw_nuss_rx_packets() function invoked from the RX NAPI callback services the interrupt. Thus, it is necessary to wait for this handler to run, drain all packets and clear TDCM, before calling napi_disable() in am65_cpsw_nuss_common_stop() function post channel teardown. If napi_disable() executes before ensuring that TDCM is cleared, the TDCM remains set when the interfaces are down, resulting in an interrupt storm when the interfaces are brought up again. Since the interrupt raised to indicate the RX DMA Channel teardown is specific to the AM62x and AM64x SoCs, add a quirk for it.

Tasev bisected to a47126ec29f5 ("PCI/PTM: Cache PTM Capability offset"), but we can't figure out how that could be related. Mark saw the same symptoms and bisected to 4ff116d0d5fd ("PCI/ASPM: Save L1 PM Substates Capability for suspend/resume"), which does have a connection: it restores L1 Substates configuration while ASPM L1 may be enabled: pci_restore_state pci_restore_aspm_l1ss_state aspm_program_l1ss pci_write_config_dword(PCI_L1SS_CTL1, ctl1) # L1SS restore pci_restore_pcie_state pcie_capability_write_word(PCI_EXP_LNKCTL, cap[i++]) # L1 restore which is a problem because PCIe r6.0, sec 5.5.4, requires that: If setting either or both of the enable bits for ASPM L1 PM Substates, both ports must be configured as described in this section while ASPM L1 is disabled. Separately, Thomas Witt reported that 5e85eba6f50d ("PCI/ASPM: Refactor L1 PM Substates Control Register programming") broke suspend/resume, and it depends on 4ff116d0d5fd. Revert 4ff116d0d5fd ("PCI/ASPM: Save L1 PM Substates Capability for suspend/resume") to fix the resume issue and enable revert of 5e85eba6f50d to fix the issue Thomas reported. Note that reverting 4ff116d0d5fd means L1 Substates config may be lost on suspend/resume. As far as we know the system will use more power but will still *work* correctly.

2023-02-10drm/ast: Fix start address computationJocelyn Falempe
During the driver conversion to shmem, the start address for the scanout buffer was set to the base PCI address. In most cases it works because only the lower 24bits are used, and due to alignment it was almost always 0. But on some unlucky hardware, it's not the case, and some uninitialized memory is displayed on the BMC. With shmem, the primary plane is always at offset 0 in GPU memory. * v2: rewrite the patch to set the offset to 0. (Thomas Zimmermann) * v3: move the change to plane_init() and also fix the cursor plane. (Jammy Huang) Tested on a sr645 affected by this bug.

2023-02-10KVM: x86: Mitigate the cross-thread return address predictions bugTom Lendacky
By default, KVM/SVM will intercept attempts by the guest to transition out of C0. However, the KVM_CAP_X86_DISABLE_EXITS capability can be used by a VMM to change this behavior. To mitigate the cross-thread return address predictions bug (X86_BUG_SMT_RSB), a VMM must not be allowed to override the default behavior to intercept C0 transitions. Use a module parameter to control the mitigation on processors that are vulnerable to X86_BUG_SMT_RSB. If the processor is vulnerable to the X86_BUG_SMT_RSB bug and the module parameter is set to mitigate the bug, KVM will not allow the disabling of the HLT, MWAIT and CSTATE exits.
