2021-01-23ALSA: usb-audio: workaround for iface reset issueTakashi Iwai1-0/+11
The recently introduced sample rate validation code seems causing a problem on some devices; namely, after performing this, the bus gets screwed and it influences even on other USB devices. As a quick workaround, perform it only for the necessary devices; currently MOTU devices are known to need the valid altset checks, so filter out other devices. Fixes: 93db51d06b32 ("ALSA: usb-audio: Check valid altsetting at parsing rates for UAC2/3") Reported-by: Jamie Heilman <[email protected]> BugLink: https://bugzilla.suse.com/show_bug.cgi?id=1178203 Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Takashi Iwai <[email protected]>
2021-01-23ALSA: pcm: One more dependency for hw constraintsTakashi Iwai2-3/+3
The fix for a long-standing USB-audio bug required one more dependency variable to be added to the hw constraints. Unfortunately I didn't realize at debugging that the new addition may result in the overflow of the dependency array of each snd_pcm_hw_rule (up to three plus a sentinel), because USB-audio driver adds one more dependency only for a certain device and bus, hence it works as is for many devices. But in a bad case, a simple open always results in -EINVAL (with kernel WARNING if CONFIG_SND_DEBUG is set) no matter what is passed. Since the dependencies are real and unavoidable (USB-audio restricts the hw_params per looping over the format/rate/channels combos), the only good solution seems to raise the bar for one more dependency for snd_pcm_hw_rule -- so does this patch: now the hw constraint dependencies can be up to four.

2021-01-23cifs: do not fail __smb_send_rqst if non-fatal signals are pendingRonnie Sahlberg1-2/+2
RHBZ 1848178 The original intent of returning an error in this function in the patch: "CIFS: Mask off signals when sending SMB packets" was to avoid interrupting packet send in the middle of sending the data (and thus breaking an SMB connection), but we also don't want to fail the request for non-fatal signals even before we have had a chance to try to send it (the reported problem could be reproduced e.g. by exiting a child process when the parent process was in the midst of calling futimens to update a file's timestamps). In addition, since the signal may remain pending when we enter the sending loop, we may end up not sending the whole packet before TCP buffers become full. In this case the code returns -EINTR but what we need here is to return -ERESTARTSYS instead to allow system calls to be restarted.

2021-01-22net: octeontx2: Make sure the buffer is 128 byte alignedKevin Hao1-1/+2
The octeontx2 hardware needs the buffer to be 128 byte aligned. But in the current implementation of napi_alloc_frag(), it can't guarantee the return address is 128 byte aligned even the request size is a multiple of 128 bytes, so we have to request an extra 128 bytes and use the PTR_ALIGN() to make sure that the buffer is aligned correctly.

2021-01-22io_uring: fix SQPOLL IORING_OP_CLOSE cancelation stateJens Axboe1-1/+2
IORING_OP_CLOSE is special in terms of cancelation, since it has an intermediate state where we've removed the file descriptor but hasn't closed the file yet. For that reason, it's currently marked with IO_WQ_WORK_NO_CANCEL to prevent cancelation. This ensures that the op is always run even if canceled, to prevent leaving us with a live file but an fd that is gone. However, with SQPOLL, since a cancel request doesn't carry any resources on behalf of the request being canceled, if we cancel before any of the close op has been run, we can end up with io-wq not having the ->files assigned.

Now that we have KTHREAD_IS_PER_CPU to denote the critical per-cpu tasks to retain during CPU offline, we can relax the warning in set_cpus_allowed_ptr(). Any spurious kthread that wants to get on at the last minute will get pushed off before it can run. While during CPU online there is no harm, and actual benefit, to allowing kthreads back on early, it simplifies hotplug code and fixes a number of outstanding races.

2021-01-22sched: Fix CPU hotplug / tighten is_per_cpu_kthread()Peter Zijlstra1-4/+35
Prior to commit 1cf12e08bc4d ("sched/hotplug: Consolidate task migration on CPU unplug") we'd leave any task on the dying CPU and break affinity and force them off at the very end. This scheme had to change in order to enable migrate_disable(). One cannot wait for migrate_disable() to complete while stuck in stop_machine(). Furthermore, since we need at the very least: idle, hotplug and stop threads at any point before stop_machine, we can't break affinity and/or push those away. Under the assumption that all per-cpu kthreads are sanely handled by CPU hotplug, the new code no long breaks affinity or migrates any of them (which then includes the critical ones above). However, there's an important difference between per-cpu kthreads and kthreads that happen to have a single CPU affinity which is lost. The latter class very much relies on the forced affinity breaking and migration semantics previously provided. Use the new kthread_is_per_cpu() infrastructure to tighten is_per_cpu_kthread() and fix the hot-unplug problems stemming from the change.

In preparation of using the balance_push state in ttwu() we need it to provide a reliable and consistent state. The immediate problem is that rq->balance_callback gets cleared every schedule() and then re-set in the balance_push_callback() itself. This is not a reliable signal, so add a variable that stays set during the entire time. Also move setting it before the synchronize_rcu() in sched_cpu_deactivate(), such that we get guaranteed visibility to ttwu(), which is a preempt-disable region.

2021-01-22kthread: Extract KTHREAD_IS_PER_CPUPeter Zijlstra3-1/+30
There is a need to distinguish geniune per-cpu kthreads from kthreads that happen to have a single CPU affinity. Geniune per-cpu kthreads are kthreads that are CPU affine for correctness, these will obviously have PF_KTHREAD set, but must also have PF_NO_SETAFFINITY set, lest userspace modify their affinity and ruins things. However, these two things are not sufficient, PF_NO_SETAFFINITY is also set on other tasks that have their affinities controlled through other means, like for instance workqueues. Therefore another bit is needed; it turns out kthread_create_per_cpu() already has such a bit: KTHREAD_IS_PER_CPU, which is used to make kthread_park()/kthread_unpark() work correctly. Expose this flag and remove the implicit setting of it from kthread_create_on_cpu(); the io_uring usage of it seems dubious at best.

The scheduler won't break affinity for us any more, and we should "emulate" the same behavior when the scheduler breaks affinity for us. The behavior is "changing the cpumask to cpu_possible_mask". And there might be some other CPUs online later while the worker is still running with the pending work items. The worker should be allowed to use the later online CPUs as before and process the work items ASAP. If we use cpu_active_mask here, we can't achieve this goal but using cpu_possible_mask can.

For most tasks this will be done automagically via BALANCE_PUSH, but percpu kthreads will have to cooperate and move themselves away one way or another. Currently, some percpu kthreads (workqueues being a notable exemple) do not cooperate nicely and can end up on an out-going CPU at the time sched_cpu_dying() is invoked.

With commit eaa7995c529b54 (regulator: core: avoid regulator_resolve_supply() race condition) we started holding the rdev lock while resolving supplies, an operation that requires holding the regulator_list_mutex. This results in lockdep warnings since in other places we take the list mutex then the mutex on an individual rdev. Since the goal is to make sure that we don't call set_supply() twice rather than a concern about the cost of resolution pull the rdev lock and check for duplicate resolution down to immediately before we do the set_supply() and drop it again once the allocation is done.

2021-01-21objtool: Don't fail on missing symbol tableJosh Poimboeuf1-2/+5
Thanks to a recent binutils change which doesn't generate unused symbols, it's now possible for thunk_64.o be completely empty without CONFIG_PREEMPTION: no text, no data, no symbols. We could edit the Makefile to only build that file when CONFIG_PREEMPTION is enabled, but that will likely create confusion if/when the thunks end up getting used by some other code again. Just ignore it and move on.

2021-01-21objtool: Don't fail the kernel build on fatal errorsJosh Poimboeuf1-9/+5
This is basically a revert of commit 644592d32837 ("objtool: Fail the kernel build on fatal errors"). That change turned out to be more trouble than it's worth. Failing the build is an extreme measure which sometimes gets too much attention and blocks CI build testing. These fatal-type warnings aren't yet as rare as we'd hope, due to the ever-increasing matrix of supported toolchains/plugins and their fast-changing nature as of late. Also, there are more people (and bots) looking for objtool warnings than ever before, so even non-fatal warnings aren't likely to be ignored for long.

2021-01-21perf script: Fix overrun issue for dynamically-allocated PMU type numberJin Yao1-1/+17
When unpacking the event which is from dynamic PMU, the array output[OUTPUT_TYPE_MAX] may be overrun. For example, type number of SKL uncore_imc is 10, but OUTPUT_TYPE_MAX is 7 now (OUTPUT_TYPE_MAX = PERF_TYPE_MAX + 1). /* In builtin-script.c */ process_event() { unsigned int type = output_type(attr->type); if (output[type].fields == 0) return; } output[10] is overrun. Create a type OUTPUT_TYPE_OTHER for dynamic PMU events, then output_type(attr->type) will return OUTPUT_TYPE_OTHER here. Note that if PERF_TYPE_MAX ever changed, then there would be a conflict between old perf.data files that had a dynamicaliy allocated PMU number that would then be the same as a fixed PERF_TYPE.
