doorbell rings
After napi_complete_done() is called when NAPI is polling in the current
process context, another NAPI may be scheduled and start running in
softirq on another CPU and may ring the doorbell before the current CPU
does. When combined with unnecessary rings when there is no need to arm
the CQ, it triggers error paths in the hardware.
This patch fixes this by calling napi_complete_done() after doorbell
rings. It limits the number of unnecessary rings when there is
no need to arm. MANA hardware specifies that there must be one doorbell
ring every 8 CQ wraparounds. This driver guarantees one doorbell ring as
soon as the number of consumed CQEs exceeds 4 CQ wraparounds. In practical
workloads, the 4 CQ wraparounds proves to be big enough that it rarely
exceeds this limit before all the napi weight is consumed.
To implement this, add a per-CQ counter cq->work_done_since_doorbell,
and make sure the CQ is armed as soon as passing 4 wraparounds of the CQ.

The commit f7866c358733 ("bpf: Fix null pointer dereference in resolve_prog_type() for BPF_PROG_TYPE_EXT")
fixed a NULL pointer dereference panic, but didn't fix the issue that
fails to update attached freplace prog to prog_array map.
Since commit 1c123c567fb1 ("bpf: Resolve fext program type when checking map compatibility"),
freplace prog and its target prog are able to tail call each other.
And the commit 3aac1ead5eb6 ("bpf: Move prog->aux->linked_prog and trampoline into bpf_link on attach")
sets prog->aux->dst_prog as NULL after attaching freplace prog to its
target prog.
After loading freplace the prog_array's owner type is BPF_PROG_TYPE_SCHED_CLS.
Then, after attaching freplace its prog->aux->dst_prog is NULL.
Then, while updating freplace in prog_array the bpf_prog_map_compatible()
incorrectly returns false because resolve_prog_type() returns
BPF_PROG_TYPE_EXT instead of BPF_PROG_TYPE_SCHED_CLS.
After this patch the resolve_prog_type() returns BPF_PROG_TYPE_SCHED_CLS
and update to prog_array can succeed.

The NETFS_RREQ_USE_PGPRIV2 and NETFS_RREQ_WRITE_TO_CACHE flags aren't used
correctly. The problem is that we try to set them up in the request
initialisation, but we the cache may be in the process of setting up still,
and so the state may not be correct. Further, we secondarily sample the
cache state and make contradictory decisions later.
The issue arises because we set up the cache resources, which allows the
cache's ->prepare_read() to switch on NETFS_SREQ_COPY_TO_CACHE - which
triggers cache writing even if we didn't set the flags when allocating.
Fix this in the following way:
(1) Drop NETFS_ICTX_USE_PGPRIV2 and instead set NETFS_RREQ_USE_PGPRIV2 in
->init_request() rather than trying to juggle that in
netfs_alloc_request().
(2) Repurpose NETFS_RREQ_USE_PGPRIV2 to merely indicate that if caching is
to be done, then PG_private_2 is to be used rather than only setting
it if we decide to cache and then having netfs_rreq_unlock_folios()
set the non-PG_private_2 writeback-to-cache if it wasn't set.
(3) Split netfs_rreq_unlock_folios() into two functions, one of which
contains the deprecated code for using PG_private_2 to avoid
accidentally doing the writeback path - and always use it if
USE_PGPRIV2 is set.
(4) As NETFS_ICTX_USE_PGPRIV2 is removed, make netfs_write_begin() always
wait for PG_private_2. This function is deprecated and only used by
ceph anyway, and so label it so.
(5) Drop the NETFS_RREQ_WRITE_TO_CACHE flag and use
fscache_operation_valid() on the cache_resources instead. This has
the advantage of picking up the result of netfs_begin_cache_read() and
fscache_begin_write_operation() - which are called after the object is
initialised and will wait for the cache to come to a usable state.
Just reverting ae678317b95e[1] isn't a sufficient fix, so this need to be
applied on top of that. Without this as well, things like:
rcu: INFO: rcu_sched detected expedited stalls on CPUs/tasks: {
and:
WARNING: CPU: 13 PID: 3621 at fs/ceph/caps.c:3386
may happen, along with some UAFs due to PG_private_2 not getting used to
wait on writeback completion.

spi: Add empty versions of ACPI lookup functions
A patch from Richard Fitzgerald adding dummy versions of the ACPI lookup
functions for SPI:
Provide empty versions of acpi_spi_count_resources(),
acpi_spi_device_alloc() and acpi_spi_find_controller_by_adev()
if the real functions are not being built.
This commit fixes two problems with the original definitions:
1) There wasn't an empty version of these functions
2) The #if only depended on CONFIG_ACPI. But the functions are implemented
in the core spi.c so CONFIG_SPI_MASTER must also be enabled for the real
functions to exist.

Both ethtool_ops.rxfh_max_context_id and the default value used when
it's not specified are supposed to be exclusive maxima (the former
is documented as such; the latter, U32_MAX, cannot be used as an ID
since it equals ETH_RXFH_CONTEXT_ALLOC), but xa_alloc() expects an
inclusive maximum.
Subtract one from 'limit' to produce an inclusive maximum, and pass
that to xa_alloc().
Increase bnxt's max by one to prevent a (very minor) regression, as
BNXT_MAX_ETH_RSS_CTX is an inclusive max. This is safe since bnxt
is not actually hard-limited; BNXT_MAX_ETH_RSS_CTX is just a
leftover from old driver code that managed context IDs itself.
Rename rxfh_max_context_id to rxfh_max_num_contexts to make its
semantics (hopefully) more obvious.

counter, use the refcount interface. It has various checks to make sure

copy_fd_bitmaps(new, old, count) is expected to copy the first
count/BITS_PER_LONG bits from old->full_fds_bits[] and fill
the rest with zeroes. What it does is copying enough words
(BITS_TO_LONGS(count/BITS_PER_LONG)), then memsets the rest.
That works fine, *if* all bits past the cutoff point are
clear. Otherwise we are risking garbage from the last word
we'd copied.
For most of the callers that is true - expand_fdtable() has
count equal to old->max_fds, so there's no open descriptors
past count, let alone fully occupied words in ->open_fds[],
which is what bits in ->full_fds_bits[] correspond to.
The other caller (dup_fd()) passes sane_fdtable_size(old_fdt, max_fds),
which is the smallest multiple of BITS_PER_LONG that covers all
opened descriptors below max_fds. In the common case (copying on
fork()) max_fds is ~0U, so all opened descriptors will be below
it and we are fine, by the same reasons why the call in expand_fdtable()
is safe.
Unfortunately, there is a case where max_fds is less than that
and where we might, indeed, end up with junk in ->full_fds_bits[] -
close_range(from, to, CLOSE_RANGE_UNSHARE) with
* descriptor table being currently shared
* 'to' being above the current capacity of descriptor table
* 'from' being just under some chunk of opened descriptors.
In that case we end up with observably wrong behaviour - e.g. spawn
a child with CLONE_FILES, get all descriptors in range 0..127 open,
then close_range(64, ~0U, CLOSE_RANGE_UNSHARE) and watch dup(0) ending
up with descriptor #128, despite #64 being observably not open.
The minimally invasive fix would be to deal with that in dup_fd().
If this proves to add measurable overhead, we can go that way, but
let's try to fix copy_fd_bitmaps() first.
* new helper: bitmap_copy_and_expand(to, from, bits_to_copy, size).
* make copy_fd_bitmaps() take the bitmap size in words, rather than
bits; it's 'count' argument is always a multiple of BITS_PER_LONG,
so we are not losing any information, and that way we can use the
same helper for all three bitmaps - compiler will see that count
is a multiple of BITS_PER_LONG for the large ones, so it'll generate
plain memcpy()+memset().

When a reference counter is at zero and refcount_sub_and_test() is invoked
to subtract zero, the function accepts this request without any warning and
returns true. This behavior does not seem ideal because the counter being
already at zero indicates a use-after-free. Furthermore, returning true by
refcount_sub_and_test() in this case potentially results in a double-free
done by its caller.
Modify the underlying function __refcount_sub_and_test() to warn about this
case as a use-after-free and have it return false to avoid the potential
double-free.

Use the late-read buffer in the CS35L56 SoundWire interface to
read OTP memory.
The OTP memory has a longer access latency than chip registers
and cannot guarantee to return the data value in the SoundWire
control response if the bus clock is >4.8 MHz. The Cirrus
SoundWire peripheral IP exposes the bridge-to-bus read buffer
and status bits. For a read from OTP the bridge status bits are
polled to wait for the OTP data to be loaded into the read buffer
and the data is then read from there.

The kernel sleep profile is no longer working due to a recursive locking
bug introduced by commit 42a20f86dc19 ("sched: Add wrapper for get_wchan()
to keep task blocked")
Booting with the 'profile=sleep' kernel command line option added or
executing
# echo -n sleep > /sys/kernel/profiling
after boot causes the system to lock up.
Lockdep reports
kthreadd/3 is trying to acquire lock:
ffff93ac82e08d58 (&p->pi_lock){....}-{2:2}, at: get_wchan+0x32/0x70
but task is already holding lock:
ffff93ac82e08d58 (&p->pi_lock){....}-{2:2}, at: try_to_wake_up+0x53/0x370
with the call trace being
lock_acquire+0xc8/0x2f0

let's remove 'profile=sleep' support based on the assumption that nobody
needs this functionality.

The runtime constants linker script depended on documented linker
behavior [1]:
"If an output section’s name is the same as the input section’s name
and is representable as a C identifier, then the linker will
automatically PROVIDE two symbols: __start_SECNAME and __stop_SECNAME,
where SECNAME is the name of the section. These indicate the start
address and end address of the output section respectively"
to just automatically define the symbol names for the bounds of the
runtime constant arrays.
It turns out that this isn't actually something we can rely on, with old
linkers not generating these automatic symbols. It looks to have been
introduced in binutils-2.29 back in 2017, and we still support building
with versions all the way back to binutils-2.25 (from 2015).
And yes, Oleg actually seems to be using such ancient versions of
binutils.
So instead of depending on the implicit symbols from "section names
match and are representable C identifiers", just do this all manually.
It's not like it causes us any extra pain, we already have to do that
for all the other sections that we use that often have special
characters in them.

Despite multiple attempts to get the syscall number assignment right
for the newly added uretprobe syscall, we ended up with a bit of a mess:
- The number is defined as 467 based on the assumption that the
xattrat family of syscalls would use 463 through 466, but those
did not make it into 6.11.
- The include/uapi/asm-generic/unistd.h file still lists the number
463, but the new scripts/syscall.tbl that was supposed to have the
same data lists 467 instead as the number for arc, arm64, csky,
hexagon, loongarch, nios2, openrisc and riscv. None of these
architectures actually provide a uretprobe syscall.
- All the other architectures (powerpc, arm, mips, ...) don't list
this syscall at all.
There are two ways to make it consistent again: either list it with
the same syscall number on all architectures, or only list it on x86
but not in scripts/syscall.tbl and asm-generic/unistd.h.
Based on the most recent discussion, it seems like we won't need it
anywhere else, so just remove the inconsistent assignment and instead
move the x86 number to the next available one in the architecture

Add new helper functions snd_soc_component_get_kcontrol() and
snd_soc_component_get_kcontrol_locked() that returns a kcontrol
by name, but will factor in the components name_prefix, to handle
situations where multiple components are present with the same
controls.

We want to determine the size of the devcoredump before writing it out.
To that end, we will run the devcoredump printer with NULL data to get
the size, alloc data based on the generated offset, then run the
devcorecump again with a valid data pointer to print. This necessitates
not writing data to the data pointer on the initial pass, when it is
NULL.
v5:
- Better commit message (Jonathan)
- Add kerenl doc with examples (Jani)
