{cis,bis}_capable only indicates the controller supports the feature
since it doesn't check that LE is enabled so it shall not be used for
current setting, instead this introduces {cis,bis}_enabled macros that
can be used to indicate that these features are currently enabled.

This issue applies for the following qdiscs: hhf, fq, fq_codel, and
fq_pie, and occurs in their change handlers when adjusting to the new
limit. The problem is the following in the values passed to the
subsequent qdisc_tree_reduce_backlog call given a tbf parent:
When the tbf parent runs out of tokens, skbs of these qdiscs will
be placed in gso_skb. Their peek handlers are qdisc_peek_dequeued,
which accounts for both qlen and backlog. However, in the case of
qdisc_dequeue_internal, ONLY qlen is accounted for when pulling
from gso_skb. This means that these qdiscs are missing a
qdisc_qstats_backlog_dec when dropping packets to satisfy the
new limit in their change handlers.
One can observe this issue with the following (with tc patched to
support a limit of 0):
export TARGET=fq
tc qdisc del dev lo root
tc qdisc add dev lo root handle 1: tbf rate 8bit burst 100b latency 1ms
tc qdisc replace dev lo handle 3: parent 1:1 $TARGET limit 1000
echo ''; echo 'add child'; tc -s -d qdisc show dev lo
ping -I lo -f -c2 -s32 -W0.001 127.0.0.1 2>&1 >/dev/null
echo ''; echo 'after ping'; tc -s -d qdisc show dev lo
tc qdisc change dev lo handle 3: parent 1:1 $TARGET limit 0
echo ''; echo 'after limit drop'; tc -s -d qdisc show dev lo
tc qdisc replace dev lo handle 2: parent 1:1 sfq
echo ''; echo 'post graft'; tc -s -d qdisc show dev lo
The second to last show command shows 0 packets but a positive
number (74) of backlog bytes. The problem becomes clearer in the
last show command, where qdisc_purge_queue triggers
qdisc_tree_reduce_backlog with the positive backlog and causes an
underflow in the tbf parent's backlog (4096 Mb instead of 0).
To fix this issue, the codepath for all clients of qdisc_dequeue_internal
has been simplified: codel, pie, hhf, fq, fq_pie, and fq_codel.
qdisc_dequeue_internal handles the backlog adjustments for all cases that
do not directly use the dequeue handler.
The old fq_codel_change limit adjustment loop accumulated the arguments to
the subsequent qdisc_tree_reduce_backlog call through the cstats field.
However, this is confusing and error prone as fq_codel_dequeue could also
potentially mutate this field (which qdisc_dequeue_internal calls in the
non gso_skb case), so we have unified the code here with other qdiscs.

syzbot found a race condition when kcm_unattach(psock)
and kcm_release(kcm) are executed at the same time.
kcm_unattach() is missing a check of the flag
kcm->tx_stopped before calling queue_work().
If the kcm has a reserved psock, kcm_unattach() might get executed
between cancel_work_sync() and unreserve_psock() in kcm_release(),
requeuing kcm->tx_work right before kcm gets freed in kcm_done().
Remove kcm->tx_stopped and replace it by the less
error-prone disable_work_sync().

kcov_remote_start_usb_softirq() the begin of urb's completion callback.
HCDs marked HCD_BH will invoke this function from the softirq and
in_serving_softirq() will detect this properly.
Root-HUB (RH) requests will not be delayed to softirq but complete
immediately in IRQ context.
This will confuse kcov because in_serving_softirq() will report true if
the softirq is served after the hardirq and if the softirq got
interrupted by the hardirq in which currently runs.
This was addressed by simply disabling interrupts in
kcov_remote_start_usb_softirq() which avoided the interruption by the RH
while a regular completion callback was invoked.
This not only changes the behaviour while kconv is enabled but also
breaks PREEMPT_RT because now sleeping locks can no longer be acquired.
Revert the previous fix. Address the issue by invoking
kcov_remote_start_usb() only if the context is just "serving softirqs"
which is identified by checking in_serving_softirq() and in_hardirq()
must be false.

The __clear_task_blocked_on() helper added a number of sanity
checks ensuring we hold the mutex wait lock and that the task
we are clearing blocked_on pointer (if set) matches the mutex.
However, there is an edge case in the _ww_mutex_wound() logic
where we need to clear the blocked_on pointer for the task that
owns the mutex, not the task that is waiting on the mutex.
For this case the sanity checks aren't valid, so handle this
by allowing a NULL lock to skip the additional checks.
K Prateek Nayak and Maarten Lankhorst also pointed out that in
this case where we don't hold the owner's mutex wait_lock, we
need to be a bit more careful using READ_ONCE/WRITE_ONCE in both
the __clear_task_blocked_on() and __set_task_blocked_on()
implementations to avoid accidentally tripping WARN_ONs if two
instances race. So do that here as well.
This issue was easier to miss, I realized, as the test-ww_mutex
driver only exercises the wait-die class of ww_mutexes. I've
sent a patch[1] to address this so the logic will be easier to
test.

The estimator kthreads' affinity are defined by sysctl overwritten
preferences and applied through a plain call to the scheduler's affinity
API.
However since the introduction of managed kthreads preferred affinity,
such a practice shortcuts the kthreads core code which eventually
overwrites the target to the default unbound affinity.
Fix this with using the appropriate kthread's API.

Currently when adding devlink port, phys_port_name is automatically
generated within devlink port initialization flow. As a result adding
devlink port support to driver may result in forced changes of interface
names, which breaks already existing network configs.
This is an expected behavior but in some scenarios it would not be
preferable to provide such limitation for legacy driver not being able to
keep 'pre-devlink' interface name.
Add flag no_phys_port_name to devlink_port_attrs struct which indicates
if devlink should not alter name of interface.

We have to make sure that all future NAPIs will have the right threaded
state when the state is configured on the device level.
We chose not to have an "unset" state for threaded, and not to wipe
the NAPI config clean when channels are explicitly disabled.
This means the persistent config structs "exist" even when their NAPIs
are not instantiated.
Differently put - the NAPI persistent state lives in the net_device
(ncfg == struct napi_config):
,--- [napi 0] - [napi 1]
[dev] | |
`--- [ncfg 0] - [ncfg 1]
so say we a device with 2 queues but only 1 enabled:
,--- [napi 0]
[dev] |
`--- [ncfg 0] - [ncfg 1]
now we set the device to threaded=1:
,---------- [napi 0 (thr:1)]
[dev(thr:1)] |
`---------- [ncfg 0 (thr:1)] - [ncfg 1 (thr:?)]
Since [ncfg 1] was not attached to a NAPI during configuration we
skipped it. If we create a NAPI for it later it will have the old
setting (presumably disabled). One could argue if this is right
or not "in principle", but it's definitely not how things worked
before per-NAPI config..

The current iosys_map_clear() implementation reads the potentially
uninitialized 'is_iomem' boolean field to decide which union member
to clear. This causes undefined behavior when called on uninitialized
structures, as 'is_iomem' may contain garbage values like 0xFF.
UBSAN detects this as:
UBSAN: invalid-load in include/linux/iosys-map.h:267
load of value 255 is not a valid value for type '_Bool'
Fix by unconditionally clearing the entire structure with memset(),
eliminating the need to read uninitialized data and ensuring all
fields are set to known good values.

Christoph suggested that the explicit _GPL_ can be dropped from the
module namespace export macro, as it's intended for in-tree modules
only. It would be possible to restrict it technically, but it was
pointed out [2] that some cases of using an out-of-tree build of an
in-tree module with the same name are legitimate. But in that case those
also have to be GPL anyway so it's unnecessary to spell it out in the
macro name.

Page pool can have pages "directly" (locklessly) recycled to it,
if the NAPI that owns the page pool is scheduled to run on the same CPU.
To make this safe we check that the NAPI is disabled while we destroy
the page pool. In most cases NAPI and page pool lifetimes are tied
together so this happens naturally.
The queue API expects the following order of calls:
-> mem_alloc
alloc new pp
-> stop
napi_disable
-> start
napi_enable
-> mem_free
free old pp
Here we allocate the page pool in ->mem_alloc and free in ->mem_free.
But the NAPIs are only stopped between ->stop and ->start. We created
page_pool_disable_direct_recycling() to safely shut down the recycling
in ->stop. This way the page_pool_destroy() call in ->mem_free doesn't
have to worry about recycling any more.
Unfortunately, the page_pool_disable_direct_recycling() is not enough
to deal with failures which necessitate freeing the _new_ page pool.
If we hit a failure in ->mem_alloc or ->stop the new page pool has
to be freed while the NAPI is active (assuming driver attaches the
page pool to an existing NAPI instance and doesn't reallocate NAPIs).
Freeing the new page pool is technically safe because it hasn't been
used for any packets, yet, so there can be no recycling. But the check
in napi_assert_will_not_race() has no way of knowing that. We could
check if page pool is empty but that'd make the check much less likely
to trigger during development.
Add page_pool_enable_direct_recycling(), pairing with
page_pool_disable_direct_recycling(). It will allow us to create the new
page pools in "disabled" state and only enable recycling when we know
the reconfig operation will not fail.
Coincidentally it will also let us re-enable the recycling for the old
pool, if the reconfig failed:
-> mem_alloc (new)
-> stop (old)
# disables direct recycling for old
-> start (new)
# fail!!
-> start (old)
# go back to old pp but direct recycling is lost :(
-> mem_free (new)
The new helper is idempotent to make the life easier for drivers,
which can operate in HDS mode and support zero-copy Rx.
The driver can call the helper twice whether there are two pools
or it has multiple references to a single pool.

Define a new, optional, callback that allows the driver to
specify how the return data buffer is allocated. If that callback
is set, mailbox/pcc.c is now responsible for reading from and
writing to the PCC shared buffer.
This also allows for proper checks of the Commnand complete flag
between the PCC sender and receiver.
For Type 4 channels, initialize the command complete flag prior
to accepting messages.
Since the mailbox does not know what memory allocation scheme
to use for response messages, the client now has an optional
callback that allows it to allocate the buffer for a response
message.
When an outbound message is written to the buffer, the mailbox
checks for the flag indicating the client wants an tx complete
notification via IRQ. Upon receipt of the interrupt It will
pair it with the outgoing message. The expected use is to
free the kernel memory buffer for the previous outgoing message.

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.

This was missed during the initial implementation. The VFIO PCI encodes
the vf_token inside the device name when opening the device from the group
FD, something like:
"0000:04:10.0 vf_token=bd8d9d2b-5a5f-4f5a-a211-f591514ba1f3"
This is used to control access to a VF unless there is co-ordination with
the owner of the PF.
Since we no longer have a device name in the cdev path, pass the token
directly through VFIO_DEVICE_BIND_IOMMUFD using an optional field
indicated by VFIO_DEVICE_BIND_FLAG_TOKEN.

Pull non-MM updates from Andrew Morton:
"Significant patch series in this pull request:
- "squashfs: Remove page->mapping references" (Matthew Wilcox) gets
us closer to being able to remove page->mapping
- "relayfs: misc changes" (Jason Xing) does some maintenance and
minor feature addition work in relayfs
- "kdump: crashkernel reservation from CMA" (Jiri Bohac) switches
us from static preallocation of the kdump crashkernel's working
memory over to dynamic allocation. So the difficulty of a-priori
estimation of the second kernel's needs is removed and the first
kernel obtains extra memory
- "generalize panic_print's dump function to be used by other
kernel parts" (Feng Tang) implements some consolidation and
rationalization of the various ways in which a failing kernel
splats information at the operator

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull more tracing updates from Steven Rostedt:
- Remove unneeded goto out statements
Over time, the logic was restructured but left a "goto out" where the
out label simply did a "return ret;". Instead of jumping to this out
label, simply return immediately and remove the out label.
- Add guard(ring_buffer_nest)
Some calls to the tracing ring buffer can happen when the ring buffer
is already being written to at the same context (for example, a
trace_printk() in between a ring_buffer_lock_reserve() and a
ring_buffer_unlock_commit()).
In order to not trigger the recursion detection, these functions use
ring_buffer_nest_start() and ring_buffer_nest_end(). Create a guard()
for these functions so that their use cases can be simplified and not
need to use goto for the release.
- Clean up the tracing code with guard() and __free() logic
There were several locations that were prime candidates for using
guard() and __free() helpers. Switch them over to use them.
- Fix output of function argument traces for unsigned int values
The function tracer with "func-args" option set will record up to 6
argument registers and then use BTF to format them for human
consumption when the trace file is read. There are several arguments
that are "unsigned long" and even "unsigned int" that are either and
address or a mask. It is easier to understand if they were printed
using hexadecimal instead of decimal. The old method just printed all
non-pointer values as signed integers, which made it even worse for
unsigned integers.
For instance, instead of:
__local_bh_disable_ip(ip=-2127311112, cnt=256) <-handle_softirqs
show:
__local_bh_disable_ip(ip=0xffffffff8133cef8, cnt=0x100) <-handle_softirqs"
