In ksmbd_extract_shortname(), strscpy() is incorrectly called with the
length of the source string (excluding the NUL terminator) rather than
the size of the destination buffer. This results in "__" being copied
to 'extension' rather than "___" (two underscores instead of three).
Use the destination buffer size instead to ensure that the string "___"
(three underscores) is copied correctly.

There's no need for separate conn_wait and disconn_wait queues.
This will simplify the move to common code, the server code

vmd_msi_alloc() allocates struct vmd_irq and stashes it into
irq_data->chip_data associated with the VMD's interrupt domain.
vmd_msi_free() extracts the pointer by calling irq_get_chip_data() and
frees it.
irq_get_chip_data() returns the chip_data associated with the top interrupt
domain. This worked in the past because VMD's interrupt domain was the top
domain.
But d7d8ab87e3e7 ("PCI: vmd: Switch to msi_create_parent_irq_domain()")
changed the interrupt domain hierarchy so VMD's interrupt domain is not the
top domain anymore. irq_get_chip_data() now returns the chip_data at the
MSI devices' interrupt domains. It is therefore broken for vmd_msi_free()
to kfree() this chip_data.
Fix by extracting the chip_data associated with the VMD's interrupt domain.

v1 -> v2: Introduce no_ioctl_enable (Jiri).
Hi,
This series fixes a regression caused by moving UID filtering to BPF.
The regression affects all events that support auxiliary data, most
notably, "cycles" events on s390, but also PT events on Intel. The
symptom is missing events when UID filtering is enabled.
Patch 1 introduces a new option for the
bpf_program__attach_perf_event_opts() function.
Patch 2 makes use of it in perf, and also contains a lot of technical
details of why exactly the problem is occurring.
Thanks to Thomas Richter for the investigation and the initial version
of this fix, and to Jiri Olsa for suggestions.
Best regards,
Ilya

On s390, and, in general, on all platforms where the respective event
supports auxiliary data gathering, the command:
# ./perf record -u 0 -aB --synth=no -- ./perf test -w thloop
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.011 MB perf.data ]
# ./perf report --stats | grep SAMPLE
#
does not generate samples in the perf.data file. On x86 the command:
# sudo perf record -e intel_pt// -u 0 ls
is broken too.
Looking at the sequence of calls in 'perf record' reveals this
behavior:
1. The event 'cycles' is created and enabled:
record__open()
+-> evlist__apply_filters()
+-> perf_bpf_filter__prepare()
+-> bpf_program.attach_perf_event()
+-> bpf_program.attach_perf_event_opts()
+-> __GI___ioctl(..., PERF_EVENT_IOC_ENABLE, ...)
The event 'cycles' is enabled and active now. However the event's
ring-buffer to store the samples generated by hardware is not
allocated yet.
2. The event's fd is mmap()ed to create the ring buffer:
record__open()
+-> record__mmap()
+-> record__mmap_evlist()
+-> evlist__mmap_ex()
+-> perf_evlist__mmap_ops()
+-> mmap_per_cpu()
+-> mmap_per_evsel()
+-> mmap__mmap()
+-> perf_mmap__mmap()
+-> mmap()
This allocates the ring buffer for the event 'cycles'. With mmap()
the kernel creates the ring buffer:
perf_mmap(): kernel function to create the event's ring
| buffer to save the sampled data.
|
+-> ring_buffer_attach(): Allocates memory for ring buffer.
| The PMU has auxiliary data setup function. The
| has_aux(event) condition is true and the PMU's
| stop() is called to stop sampling. It is not
| restarted:
|
| if (has_aux(event))
| perf_event_stop(event, 0);
|
+-> cpumsf_pmu_stop():
Hardware sampling is stopped. No samples are generated and saved
anymore.
3. After the event 'cycles' has been mapped, the event is enabled a
second time in:
__cmd_record()
+-> evlist__enable()
+-> __evlist__enable()
+-> evsel__enable_cpu()
+-> perf_evsel__enable_cpu()
+-> perf_evsel__run_ioctl()
+-> perf_evsel__ioctl()
+-> __GI___ioctl(., PERF_EVENT_IOC_ENABLE, .)
The second
ioctl(fd, PERF_EVENT_IOC_ENABLE, 0);
is just a NOP in this case. The first invocation in (1.) sets the
event::state to PERF_EVENT_STATE_ACTIVE. The kernel functions
perf_ioctl()
+-> _perf_ioctl()
+-> _perf_event_enable()
+-> __perf_event_enable()
return immediately because event::state is already set to
PERF_EVENT_STATE_ACTIVE.
This happens on s390, because the event 'cycles' offers the possibility
to save auxilary data. The PMU callbacks setup_aux() and free_aux() are
defined. Without both callback functions, cpumsf_pmu_stop() is not
invoked and sampling continues.
To remedy this, remove the first invocation of
ioctl(..., PERF_EVENT_IOC_ENABLE, ...).
in step (1.) Create the event in step (1.) and enable it in step (3.)
after the ring buffer has been mapped.
Output after:
# ./perf record -aB --synth=no -u 0 -- ./perf test -w thloop 2
[ perf record: Woken up 3 times to write data ]
[ perf record: Captured and wrote 0.876 MB perf.data ]
# ./perf report --stats | grep SAMPLE
SAMPLE events: 16200 (99.5%)
SAMPLE events: 16200
#
The software event succeeded both before and after the patch:
# ./perf record -e cpu-clock -aB --synth=no -u 0 -- \
./perf test -w thloop 2
[ perf record: Woken up 7 times to write data ]
[ perf record: Captured and wrote 2.870 MB perf.data ]
# ./perf report --stats | grep SAMPLE
SAMPLE events: 53506 (99.8%)
SAMPLE events: 53506

Automatically enabling a perf event after attaching a BPF prog to it is
not always desirable.
Add a new "dont_enable" field to struct bpf_perf_event_opts. While
introducing "enable" instead would be nicer in that it would avoid
a double negation in the implementation, it would make
DECLARE_LIBBPF_OPTS() less efficient.

Currently elevators will record internal 'async_depth' to throttle
asynchronous requests, and they both calculate shallow_dpeth based on
sb->shift, with the respect that sb->shift is the available tags in one
word.
However, sb->shift is not the availbale tags in the last word, see
__map_depth:
if (index == sb->map_nr - 1)
return sb->depth - (index << sb->shift);
For consequence, if the last word is used, more tags can be get than
expected, for example, assume nr_requests=256 and there are four words,
in the worst case if user set nr_requests=32, then the first word is
the last word, and still use bits per word, which is 64, to calculate
async_depth is wrong.
One the ohter hand, due to cgroup qos, bfq can allow only one request
to be allocated, and set shallow_dpeth=1 will still allow the number
of words request to be allocated.
Fix this problems by using shallow_depth to the whole sbitmap instead
of per word, also change kyber, mq-deadline and bfq to follow this,
a new helper __map_depth_with_shallow() is introduced to calculate
available bits in each word.

The split of Cirrus HD-audio codec driver may confuse users when

The split of Realtek HD-audio codec driver may cause confusions
especially when migrating from the previous kernel configurations
because it's hard to know which driver to be enabled.
Although we've already set default=y for those codec drivers, it may
still make people changing the stuff unnecessarily without knowing its
side effect.
This patch is for avoiding such pitfalls by marking the prompt of each
Realtek codec driver with CONFIG_EXPERT. For "normal" users (that is,
unless CONFIG_EXPERT is set), all Realtek HD-audio codecs are enabled
together with CONFIG_SND_HDA_CODEC_REALTEK; this is the very same
situation like the previous kernels, after all.
For users who really care about the minimalistic configuration, they
can turn each driver on/off individually after setting
CONFIG_EXPERT=y.
The patch also adds the missing help text to the top-level
CONFIG_SND_HDA_CODEC_REALTEK together with the explanation of

We only need the fw based discovery table for sysfs. No
need to parse it. Additionally parsing some of the board
specific tables may result in incorrect data on some boards.
just load the binary and don't parse it on those boards.

Since KFD proc content was moved to kernel debugfs, we can't destroy KFD
debugfs before kfd_process_destroy_wq. Move kfd_process_destroy_wq prior
to kfd_debugfs_fini to fix a kernel NULL pointer problem. It happens
when /sys/kernel/debug/kfd was already destroyed in kfd_debugfs_fini but
kfd_process_destroy_wq calls kfd_debugfs_remove_process. This line
debugfs_remove_recursive(entry->proc_dentry);
tries to remove /sys/kernel/debug/kfd/proc/<pid> while
/sys/kernel/debug/kfd is already gone. It hangs the kernel by kernel
NULL pointer.

takedown_cpu() has a comment about "all preempt/rcu users must observe
!cpu_active()" which is kind of meaningless in this function. This
comment was originally introduced by commit 6acce3ef8452 ("sched: Remove
get_online_cpus() usage") when _cpu_down() was setting cpu_active_mask
and synchronize_rcu()/synchronize_sched() were added after that.
Later commit 40190a78f85f ("sched/hotplug: Convert cpu_[in]active
notifiers to state machine") added a new CPUHP_AP_ACTIVE hotplug
state to set/clear cpu_active_mask. The following commit b2454caa8977
("sched/hotplug: Move sync_rcu to be with set_cpu_active(false)")
move the synchronize_*() calls to sched_cpu_deactivate() associated
with the new hotplug state, but left the comment behind.
Remove this comment as it is no longer relevant in takedown_cpu().

Calling enqueue_reassembly() and wake_up_interruptible(&info->wait_reassembly_queue)
or put_receive_buffer() means the response/data_transfer pointer might
get re-used by another thread, which means these should be
the last operations before calling return.

We should call put_receive_buffer() before waking up the callers.
For the internal error case of response->type being unexpected,
we now also call smbd_disconnect_rdma_connection() instead
of not waking up the callers at all.
Note that the SMBD_TRANSFER_DATA case still has problems,
which will be addressed in the next commit in order to make
it easier to review this one.
