"A fairly standard release for SPI with the exception of a change to

mm/mremap: fix vm_pgoff in vma_merge() case 3
After upgrading build guests to v6.3, rpm started segfaulting for
specific packages, which was bisected to commit
0503ea8f5ba7 ("mm/mmap:
remove __vma_adjust()"). rpm is doing many mremap() operations with file
mappings of its db. The problem is that in vma_merge() case 3 (we merge
with the next vma, expanding it downwards) vm_pgoff is not adjusted as
it should when vm_start changes. As a result the rpm process most likely
sees data from the wrong offset of the file. Fix the vm_pgoff
calculation.
For case 8 this is a non-functional change as the resulting vm_pgoff is
the same.

easier to just have a recurring timer rather than needing to rearm it
every time (David)

the kernel, and hence have strict address requirements for mmap'ing
the ring into userspace. This should only be parisc/hppa. (Helge, me)
- XFS has supported O_DIRECT writes without needing to lock the inode

Pull btrfs updates from David Sterba:
"Mostly core changes and cleanups, some notable fixes and two
performance improvements in directory logging.
The IO path cleanups are removing or refactoring old code, scrub main
loop has been completely rewritten also refactoring old code.
There are some changes to non-btrfs code, mostly trivial, the cgroup
punt bio logic is only moved from generic code.
Performance improvements:
- improve logging changes in a directory during one transaction,
avoid iterating over items and reduce lock contention (fsync time
4x lower)
- when logging directory entries during one transaction, reduce
locking of subvolume trees by checking tree-log instead
(improvement in throughput and latency for concurrent access to a
subvolume)
Notable fixes:
- dev-replace:
- properly honor read mode when requested to avoid reading from
source device
- target device won't be used for eventual read repair, this is
unreliable for NODATASUM files
- when there are unpaired (and unrepairable) metadata during
replace, exit early with error and don't try to finish whole
operation
- scrub ioctl properly rejects unknown flags
- fix global block reserve calculations
- fix partial direct io write when there's a page fault in the
middle, iomap will try to continue with partial request but the
btrfs part did not match that, this can lead to zeros written
instead of data
Core changes:
- io path:
- continued cleanups and refactoring around bio handling
- extent io submit path simplifications and cleanups
- flush write path simplifications and cleanups
- rework logic of passing sync mode of bio, with further cleanups
- rewrite scrub code flow, restructure how the stripes are enumerated
and verified in a more unified way
- allow to set lower threshold for block group reclaim in debug mode
to aid zoned mode testing
- remove obsolete time-based delayed ref throttling logic when
truncating items
- DREW locks are not using percpu variables anymore
- more warning fixes (-Wmaybe-uninitialized)
- u64 division simplifications
- error handling improvements
Non-btrfs code changes:
- push cgroup punt bio logic to btrfs code (there was no other user
of that), the functionality can be now selected separately by
BLK_CGROUP_PUNT_BIO
- crc32c_impl removed after removing last uses in btrfs code

net: phy: hide the PHYLIB_LEDS knob
commit
4bb7aac70b5d ("net: phy: fix circular LEDS_CLASS dependencies")
solved a build failure, but introduces a new config knob with a default
'y' value: PHYLIB_LEDS.
The latter is against the current new config policy. The exception
was raised to allow the user to catch bad configurations without led
support.
Anyway the current definition of PHYLIB_LEDS does not fit the above
goal: if LEDS_CLASS is disabled, the new config will be available
only with PHYLIB disabled, too.
Hide the mentioned config, to preserve the randconfig testing done so
far, while respecting the mentioned policy.

Pull regmap updates from Mark Brown:
"This is a much bigger change for regmap than is normal, the main
things being the addition of some KUnit coverage and a maple tree
based register cache which longer term is likely to replace the rbtree
cache except possibly for very small register maps.
While it's complete overkill for most applications the code for maple
trees is there and there are some larger, sparser devices where the
data structure is a better fit.
The maple tree support is still a work in progress but already useful,
there's some conversions of drivers ready to go after the merge
window.
Summary:
- Support for shifting register addresses up as well as down, there's
a use cases with memory mapped MDIO.
- Refactoring of the type configuration in regmap-irq to allow access
to driver data in the handler, needed by some GPIO devices.
- Some initial KUnit coverage, the bulk of the driver facing API is
covered but there's holes and things like the data marshalling for
bytestream buses are just not covered in the slightest.
- Removal of the compressed cache type, it had zero users and was
getting in the way of KUnit.
- Addition of a maple tree based register cache, there's more work to
do but it's already useful for some devices with a flatter data
structure than rbtree and getting to use all the optimisation work
Liam is doing"

Merge tag 'x86-apic-2023-04-24' of git://git./linux/kernel/git/tip/tip
Pull x86 APIC updates from Thomas Gleixner:
- Fix the incorrect handling of atomic offset updates in
reserve_eilvt_offset()
The check for the return value of atomic_cmpxchg() is not compared
against the old value, it is compared against the new value, which
makes it two round on success.
Convert it to atomic_try_cmpxchg() which does the right thing.
- Handle IO/APIC less systems correctly
When IO/APIC is not advertised by ACPI then the computation of the
lower bound for dynamically allocated interrupts like MSI goes wrong.
This lower bound is used to exclude the IO/APIC legacy GSI space as
that must stay reserved for the legacy interrupts.
In case that the system, e.g. VM, does not advertise an IO/APIC the
lower bound stays at 0.
0 is an invalid interrupt number except for the legacy timer
interrupt on x86. The return value is unchecked in the core code, so
it ends up to allocate interrupt number 0 which is subsequently
considered to be invalid by the caller, e.g. the MSI allocation code.
A similar problem was already cured for device tree based systems
years ago, but that missed - or did not envision - the zero IO/APIC
case.
Consolidate the zero check and return the provided "from" argument to
the core code call site, which is guaranteed to be greater than 0.
- Simplify the X2APIC cluster CPU mask logic for CPU hotplug
Per cluster CPU masks are required for X2APIC in cluster mode to
determine the correct cluster for a target CPU when calculating the
destination for IPIs
These masks are established when CPUs are borught up. The first CPU
in a cluster must allocate a new cluster CPU mask. As this happens
during the early startup of a CPU, where memory allocations cannot be
done, the mask has to be allocated by the control CPU.
The current implementation allocates a clustermask just in case and
if the to be brought up CPU is the first in a cluster the CPU takes
over this allocation from a global pointer.
This works nicely in the fully serialized CPU bringup scenario which
is used today, but would fail completely for parallel bringup of
CPUs.
The cluster association of a CPU can be computed from the APIC ID
which is enumerated by ACPI/MADT.
So the cluster CPU masks can be preallocated and associated upfront
and the upcoming CPUs just need to set their corresponding bit.
Aside of preparing for parallel bringup this is a valuable
simplification on its own.
- Remove global variables which control the early startup of secondary
CPUs on 64-bit
The only information which is needed by a starting CPU is the Linux
CPU number. The CPU number allows it to retrieve the rest of the
required data from already existing per CPU storage.
So instead of initial_stack, early_gdt_desciptor and initial_gs
provide a new variable smpboot_control which contains the Linux CPU
number for now. The starting CPU can retrieve and compute all
required information for startup from there.
Aside of being a cleanup, this is also preparing for parallel CPU
bringup, where starting CPUs will look up their Linux CPU number via
the APIC ID, when smpboot_control has the corresponding control bit
set.
- Make cc_vendor globally accesible
Subsequent parallel bringup changes require access to cc_vendor
because confidental computing platforms need special treatment in the
early startup phase vs. CPUID and APCI ID readouts.
The change makes cc_vendor global and provides stub accessors in case
that CONFIG_ARCH_HAS_CC_PLATFORM is not set.
This was merged from the x86/cc branch in anticipation of further
parallel bringup commits which require access to cc_vendor. Due to
late discoveries of fundamental issue with those patches these
commits never happened.
The merge commit is unfortunately in the middle of the APIC commits
so unraveling it would have required a rebase or revert. As the
parallel bringup seems to be well on its way for 6.5 this would be
just pointless churn. As the commit does not contain any functional
change it's not a risk to keep it.

Pull timers and timekeeping updates from Thomas Gleixner:
- Improve the VDSO build time checks to cover all dynamic relocations
VDSO does not allow dynamic relocations, but the build time check is
incomplete and fragile.
It's based on architectures specifying the relocation types to search
for and does not handle R_*_NONE relocation entries correctly.
R_*_NONE relocations are injected by some GNU ld variants if they
fail to determine the exact .rel[a]/dyn_size to cover trailing zeros.
R_*_NONE relocations must be ignored by dynamic loaders, so they
should be ignored in the build time check too.
Remove the architecture specific relocation types to check for and
validate strictly that no other relocations than R_*_NONE end up in
the VSDO .so file.
- Prefer signal delivery to the current thread for
CLOCK_PROCESS_CPUTIME_ID based posix-timers
Such timers prefer to deliver the signal to the main thread of a
process even if the context in which the timer expires is the current
task. This has the downside that it might wake up an idle thread.
As there is no requirement or guarantee that the signal has to be
delivered to the main thread, avoid this by preferring the current
task if it is part of the thread group which shares sighand.
This not only avoids waking idle threads, it also distributes the
signal delivery in case of multiple timers firing in the context of
different threads close to each other better.
- Align the tick period properly (again)
For a long time the tick was starting at CLOCK_MONOTONIC zero, which
allowed users space applications to either align with the tick or to
place a periodic computation so that it does not interfere with the
tick. The alignement of the tick period was more by chance than by
intention as the tick is set up before a high resolution clocksource
is installed, i.e. timekeeping is still tick based and the tick
period advances from there.
The early enablement of sched_clock() broke this alignement as the
time accumulated by sched_clock() is taken into account when
timekeeping is initialized. So the base value now(CLOCK_MONOTONIC) is
not longer a multiple of tick periods, which breaks applications
which relied on that behaviour.
Cure this by aligning the tick starting point to the next multiple of
tick periods, i.e 1000ms/CONFIG_HZ.
- A set of NOHZ fixes and enhancements:
* Cure the concurrent writer race for idle and IO sleeptime
statistics
The statitic values which are exposed via /proc/stat are updated
from the CPU local idle exit and remotely by cpufreq, but that
happens without any form of serialization. As a consequence
sleeptimes can be accounted twice or worse.
Prevent this by restricting the accumulation writeback to the CPU
local idle exit and let the remote access compute the accumulated
value.
* Protect idle/iowait sleep time with a sequence count
Reading idle/iowait sleep time, e.g. from /proc/stat, can race
with idle exit updates. As a consequence the readout may result
in random and potentially going backwards values.
Protect this by a sequence count, which fixes the idle time
statistics issue, but cannot fix the iowait time problem because
iowait time accounting races with remote wake ups decrementing
the remote runqueues nr_iowait counter. The latter is impossible
to fix, so the only way to deal with that is to document it
properly and to remove the assertion in the selftest which
triggers occasionally due to that.
* Restructure struct tick_sched for better cache layout
* Some small cleanups and a better cache layout for struct
tick_sched
- Implement the missing timer_wait_running() callback for POSIX CPU
timers
For unknown reason the introduction of the timer_wait_running()
callback missed to fixup posix CPU timers, which went unnoticed for
almost four years.
While initially only targeted to prevent livelocks between a timer
deletion and the timer expiry function on PREEMPT_RT enabled kernels,
it turned out that fixing this for mainline is not as trivial as just
implementing a stub similar to the hrtimer/timer callbacks.
The reason is that for CONFIG_POSIX_CPU_TIMERS_TASK_WORK enabled
systems there is a livelock issue independent of RT.
CONFIG_POSIX_CPU_TIMERS_TASK_WORK=y moves the expiry of POSIX CPU
timers out from hard interrupt context to task work, which is handled
before returning to user space or to a VM. The expiry mechanism moves
the expired timers to a stack local list head with sighand lock held.
Once sighand is dropped the task can be preempted and a task which
wants to delete a timer will spin-wait until the expiry task is
scheduled back in. In the worst case this will end up in a livelock
when the preempting task and the expiry task are pinned on the same
CPU.
The timer wheel has a timer_wait_running() mechanism for RT, which
uses a per CPU timer-base expiry lock which is held by the expiry
code and the task waiting for the timer function to complete blocks
on that lock.
This does not work in the same way for posix CPU timers as there is
no timer base and expiry for process wide timers can run on any task
belonging to that process, but the concept of waiting on an expiry
lock can be used too in a slightly different way.
Add a per task mutex to struct posix_cputimers_work, let the expiry
task hold it accross the expiry function and let the deleting task
which waits for the expiry to complete block on the mutex.
In the non-contended case this results in an extra
mutex_lock()/unlock() pair on both sides.
This avoids spin-waiting on a task which is scheduled out, prevents
the livelock and cures the problem for RT and !RT systems

Pull core debugobjects update from Thomas Gleixner:
"A single update to debugobjects:
Prevent a race vs statically initialized objects. Such objects are
usually not initialized via an init() function. They are special cased
and detected on first use under the assumption that they are already
correctly initialized via the static initializer.
This works correctly unless there are two concurrent debug object
operations on such an object.
The first one detects that the object is not yet tracked and tries to
establish a tracking object after dropping the debug objects hash
bucket lock. The concurrent operation does the same. The one which
wins the race ends up modifying the state of the object which makes
the other one fail resulting in a bogus debug objects warning.
Prevent this by making the detection of a static object and the
allocation of a tracking object atomic under the hash bucket lock. So
the first one to acquire the hash bucket lock will succeed and the
second one will observe the correct tracking state.
This race existed forever but was only exposed when the timer wheel
code added a debug_object_assert_init() call outside of the timer base
locked region. This replaced the previous warning about
timer::function being NULL which had to be removed when the
timer_shutdown() mechanics were added"

gfs2: Perform second log flush in gfs2_make_fs_ro
Before this patch, function gfs2_make_fs_ro called gfs2_log_flush once to
finalize the log. However, if there's dirty metadata, log flushes tend
to sync the metadata and formulate revokes. Before this patch, those
revokes may not be written out to the journal immediately, which meant
unresolved glocks could still have revokes in their ail lists. When the
glock worker runs, it tries to transition the glock, but the unresolved
revokes in the ail still need to be written, so it tries to start a
transaction. It's impossible to start a transaction because at that
point, the SDF_JOURNAL_LIVE flag has been cleared by gfs2_make_fs_ro.
That causes the glock worker to fail, unable to write the revokes. The
calling sequence looked something like this:
gfs2_make_fs_ro
gfs2_log_flush - with GFS2_LOG_HEAD_FLUSH_SHUTDOWN flag set
if (flags & GFS2_LOG_HEAD_FLUSH_SHUTDOWN)
clear_bit(SDF_JOURNAL_LIVE, &sdp->sd_flags);
...meanwhile...
glock_work_func
do_xmote
rgrp_go_sync (or possibly inode_go_sync)
...
gfs2_ail_empty_gl
__gfs2_trans_begin
if (unlikely(!test_bit(SDF_JOURNAL_LIVE, &sdp->sd_flags))) {
...
return -EROFS;
The previous patch in the series ("gfs2: return errors from
gfs2_ail_empty_gl") now causes the transaction error to no longer be
ignored, so it causes a warning from MOST of the xfstests:
WARNING: CPU: 11 PID: X at fs/gfs2/super.c:603 gfs2_put_super [gfs2]
which corresponds to:
WARN_ON(gfs2_withdrawing(sdp));
The withdraw was triggered silently from do_xmote by:
if (unlikely(sdp->sd_log_error && !gfs2_withdrawn(sdp)))
gfs2_withdraw_delayed(sdp);
This patch adds a second log_flush to gfs2_make_fs_ro: one to sync the
data and one to sync any outstanding revokes and finalize the journal.
Note that both of these log flushes need to be "special," in other
words, not GFS2_LOG_HEAD_FLUSH_NORMAL.

gfs2: return errors from gfs2_ail_empty_gl
Before this patch, function gfs2_ail_empty_gl did not return errors it
encountered from __gfs2_trans_begin. Those errors usually came from the
fact that the file system was made read-only, often due to unmount
(but theoretically could be due to -o remount,ro), which prevented
the transaction from starting.
The inability to start a transaction prevented its revokes from being
properly written to the journal for glocks during unmount (and
transition to ro).
That meant glocks could be unlocked without the metadata properly
revoked in the journal. So other nodes could grab the glock thinking
that their lvb values were correct, but in fact corresponded to the
glock without its revokes properly synced. That presented as lvb
mismatch errors.
This patch allows gfs2_ail_empty_gl to return the error properly to
the caller.

tcp/udp: Fix memleaks of sk and zerocopy skbs with TX timestamp.
syzkaller reported [0] memory leaks of an UDP socket and ZEROCOPY
skbs. We can reproduce the problem with these sequences:
sk = socket(AF_INET, SOCK_DGRAM, 0)
sk.setsockopt(SOL_SOCKET, SO_TIMESTAMPING, SOF_TIMESTAMPING_TX_SOFTWARE)
sk.setsockopt(SOL_SOCKET, SO_ZEROCOPY, 1)
sk.sendto(b'', MSG_ZEROCOPY, ('127.0.0.1', 53))
sk.close()
sendmsg() calls msg_zerocopy_alloc(), which allocates a skb, sets
skb->cb->ubuf.refcnt to 1, and calls sock_hold(). Here, struct
ubuf_info_msgzc indirectly holds a refcnt of the socket. When the
skb is sent, __skb_tstamp_tx() clones it and puts the clone into
the socket's error queue with the TX timestamp.
When the original skb is received locally, skb_copy_ubufs() calls
skb_unclone(), and pskb_expand_head() increments skb->cb->ubuf.refcnt.
This additional count is decremented while freeing the skb, but struct
ubuf_info_msgzc still has a refcnt, so __msg_zerocopy_callback() is
not called.
The last refcnt is not released unless we retrieve the TX timestamped
skb by recvmsg(). Since we clear the error queue in inet_sock_destruct()
after the socket's refcnt reaches 0, there is a circular dependency.
If we close() the socket holding such skbs, we never call sock_put()
and leak the count, sk, and skb.
TCP has the same problem, and commit
e0c8bccd40fc ("net: stream:
purge sk_error_queue in sk_stream_kill_queues()") tried to fix it
by calling skb_queue_purge() during close(). However, there is a
small chance that skb queued in a qdisc or device could be put
into the error queue after the skb_queue_purge() call.
In __skb_tstamp_tx(), the cloned skb should not have a reference
to the ubuf to remove the circular dependency, but skb_clone() does
not call skb_copy_ubufs() for zerocopy skb. So, we need to call
skb_orphan_frags_rx() for the cloned skb to call skb_copy_ubufs().

tsnep: XDP socket zero-copy support
Implement XDP socket zero-copy support for tsnep driver. I tried to
follow existing drivers like igc as far as possible. But one main
difference is that tsnep does not need any reconfiguration for XDP BPF
program setup. So I decided to keep this behavior no matter if a XSK
pool is used or not. As a result, tsnep starts using the XSK pool even
if no XDP BPF program is available.
Another difference is that I tried to prevent potentially failing
allocations during XSK pool setup. E.g. both memory models for page pool
and XSK pool are registered all the time. Thus, XSK pool setup cannot
end up with not working queues.
Some prework is done to reduce the last two XSK commits to actual XSK
changes.

tsnep: Add XDP socket zero-copy RX support
Add support for XSK zero-copy to RX path. The setup of the XSK pool can
be done at runtime. If the netdev is running, then the queue must be
disabled and enabled during reconfiguration. This can be done easily
with functions introduced in previous commits.
A more important property is that, if the netdev is running, then the
setup of the XSK pool shall not stop the netdev in case of errors. A
broken netdev after a failed XSK pool setup is bad behavior. Therefore,
the allocation and setup of resources during XSK pool setup is done only
before any queue is disabled. Additionally, freeing and later allocation
of resources is eliminated in some cases. Page pool entries are kept for
later use. Two memory models are registered in parallel. As a result,
the XSK pool setup cannot fail during queue reconfiguration.
In contrast to other drivers, XSK pool setup and XDP BPF program setup
are separate actions. XSK pool setup can be done without any XDP BPF
program. The XDP BPF program can be added, removed or changed without
any reconfiguration of the XSK pool.

Using batch API reduced CPU utilization slightly, but measurements are
not stable enough to provide meaningful numbers.

net: ethtool: coalesce: try to make user settings stick twice
SET_COALESCE may change operation mode and parameters in one call.
Changing operation mode may cause the driver to reset the parameter
values to what is a reasonable default for new operation mode.
Since driver does not know which parameters come from user and which
are echoed back from ->get, driver may ignore the parameters when
switching operation modes.
This used to be inevitable for ioctl() but in netlink we know which
parameters are actually specified by the user.
We could inform which parameters were set by the user but this would
lead to a lot of code duplication in the drivers. Instead try to call
the drivers twice if both mode and params are changed. The set method
already checks if any params need updating so in case the driver did
the right thing the first time around - there will be no second call
to it's ->set method (only an extra call to ->get()).
For mlx5 for example before this patch we'd see:
# ethtool -C eth0 adaptive-rx on adaptive-tx on
# ethtool -C eth0 adaptive-rx off adaptive-tx off \
tx-usecs 123 rx-usecs 123
Adaptive RX: off TX: off
rx-usecs: 3
rx-frames: 32
tx-usecs: 16
tx-frames: 32
[...]
After the change:
# ethtool -C eth0 adaptive-rx on adaptive-tx on
# ethtool -C eth0 adaptive-rx off adaptive-tx off \
tx-usecs 123 rx-usecs 123
Adaptive RX: off TX: off
rx-usecs: 123
rx-frames: 32
tx-usecs: 123
tx-frames: 32
[...]
This only works for netlink, so it's a small discrepancy between
netlink and ioctl(). Since we anticipate most users to move to
netlink I believe it's worth making their lives easier.

net: veth: add page_pool for page recycling
Introduce page_pool support in veth driver in order to recycle pages
in veth_convert_skb_to_xdp_buff routine and avoid reallocating the skb
through the page allocator.
The patch has been tested sending tcp traffic to a veth pair where the
remote peer is running a simple xdp program just returning xdp_pass:
veth upstream codebase:
MTU 1500B: ~ 8Gbps
MTU 8000B: ~ 13.9Gbps
veth upstream codebase + pp support:
MTU 1500B: ~ 9.2Gbps
MTU 8000B: ~ 16.2Gbps
