START_USER_RECOVERY and END_USER_RECOVERY are two new control commands
to support user recovery feature.
After a crash, user should send START_USER_RECOVERY, it will:
(1) check if (a)current ublk_device is UBLK_S_DEV_QUIESCED which was
set by quiesce_work and (b)chardev is released
(2) reinit all ubqs, including:
(a) put the task_struct and reset ->ubq_daemon to NULL.
(b) reset all ublk_io.
(3) reset ub->mm to NULL.
Then, user should start a new process and send FETCH_REQ on each
ubq_daemon.
Finally, user should send END_USER_RECOVERY, it will:
(1) wait for all new ubq_daemons getting ready.
(2) update ublksrv_pid
(3) unquiesce the request queue and expect incoming ublk_queue_rq()
(4) convert ub's state to UBLK_S_DEV_LIVE
Note: we can handle STOP_DEV between START_USER_RECOVERY and
END_USER_RECOVERY. This is helpful to users who cannot start new process
after sending START_USER_RECOVERY ctrl-cmd.

UBLK_F_USER_RECOVERY_REISSUE implies that:
With a dying ubq_daemon, ublk_drv let monitor_work requeues rq issued to
userspace(ublksrv) before the ubq_daemon is dying.
UBLK_F_USER_RECOVERY_REISSUE is designed for backends which:
(1) tolerate double-write since ublk_drv may issue the same rq
twice.
(2) does not let frontend users get I/O error, such as read-only FS
and VM backend.

Define some macros for recovery feature.
UBLK_S_DEV_QUIESCED implies that ublk_device is quiesced
and is ready for recovery. This state can be observed by userspace.
UBLK_F_USER_RECOVERY implies that:
(1) ublk_drv enables recovery feature. It won't let monitor_work to
automatically abort rqs and release the device.
(2) With a dying ubq_daemon, ublk_drv ends(aborts) rqs issued to
userspace(ublksrv) before crash.
(3) With a dying ubq_daemon, in task work and ublk_queue_rq(),
ublk_drv requeues rqs.

PSI tries to account for the cost of bringing back in pages discarded by
the MM LRU management. Currently the prime place for that is hooked into
the bio submission path, which is a rather bad place:
- it does not actually account I/O for non-block file systems, of which
we have many
- it adds overhead and a layering violation to the block layer
Add the accounting into the two places in the core MM code that read
pages into an address space by calling into ->read_folio and ->readahead
so that the entire file system operations are covered, to broaden
the coverage and allow removing the accounting in the block layer going
forward.
As psi_memstall_enter can deal with nested calls this will not lead to
double accounting even while the bio annotations are still present.

The problem is that the second bio is finished after 10s instead of 20s.
Root cause:
1) second bio will be flagged:
__blk_throtl_bio
while (true) {
...
if (sq->nr_queued[rw]) -> some bio is throttled already
break
};
bio_set_flag(bio, BIO_THROTTLED); -> flag the bio
2) flagged bio will be dispatched without waiting:
throtl_dispatch_tg
tg_may_dispatch
tg_with_in_bps_limit
if (bps_limit == U64_MAX || bio_flagged(bio, BIO_THROTTLED))
*wait = 0; -> wait time is zero
return true;
commit 9f5ede3c01f9 ("block: throttle split bio in case of iops limit")
support to count split bios for iops limit, thus it adds flagged bio
checking in tg_with_in_bps_limit() so that split bios will only count
once for bps limit, however, it introduce a new problem that io throttle
won't work if multiple bios are throttled.
In order to fix the problem, handle iops/bps limit in different ways:
1) for iops limit, there is no flag to record if the bio is throttled,
and iops is always applied.
2) for bps limit, original bio will be flagged with BIO_BPS_THROTTLED,
and io throttle will ignore bio with the flag.
Noted this patch also remove the code to set flag in __bio_clone(), it's
introduced in commit 111be8839817 ("block-throttle: avoid double
charge"), and author thinks split bio can be resubmited and throttled
again, which is wrong because split bio will continue to dispatch from
caller.

Provide a mechanism to retrieve basic status information about
the device, including the "supported" flag indicating whether
SED-OPAL is supported. The information returned is from the various
feature descriptors received during the discovery0 step, and so
this ioctl does nothing more than perform the discovery0 step
and then save the information received. See "struct opal_status"
and OPAL_FL_* bits for the status information currently returned.
This is necessary to be able to check whether a device is OPAL
enabled, set up, locked or unlocked from userspace programs
like systemd-cryptsetup and libcryptsetup. Right now we just
have to assume the user 'knows' or blindly attempt setup/lock/unlock
operations.

Commit 0568e6122574 ("ata: libata-scsi: cap ata_device->max_sectors
according to shost->max_sectors") inadvertently capped the max_sectors
value for some SATA disks to a value which is lower than we would want.
For a device which supports LBA48, we would previously have request queue
max_sectors_kb and max_hw_sectors_kb values of 1280 and 32767 respectively.
For AHCI controllers, the value chosen for shost max sectors comes from
the minimum of the SCSI host default max sectors in
SCSI_DEFAULT_MAX_SECTORS (1024) and the shost DMA device mapping limit.
This means that we would now set the max_sectors_kb and max_hw_sectors_kb
values for a disk which supports LBA48 at 512, ignoring DMA mapping limit.
As report by Oliver at [0], this caused a performance regression.
Fix by picking a large enough max sectors value for ATA host controllers
such that we don't needlessly reduce max_sectors_kb for LBA48 disks.

The motivation of this renaming is to make these variables and related
helper functions less mmu_notifier bound and can also be used for non
mmu_notifier based page invalidation. mmu_invalidate_* was chosen to
better describe the purpose of 'invalidating' a page that those
variables are used for.

mmu_invalidate_seq/range_start/range_end.
- mmu_notifier_retry{_hva} helper functions are renamed to
mmu_invalidate_retry{_hva}.
- mmu_notifier_count is renamed to mmu_invalidate_in_progress to
avoid confusion with mn_active_invalidate_count.
- While here, also update kvm_inc/dec_notifier_count() to
kvm_mmu_invalidate_begin/end() to match the change for
mmu_notifier_count.

With so many counter addresses recently discovered as being wrong, it is
desirable to at least have a central database of information, rather
than two: one through the SYS_COUNT_* registers (used for
ndo_get_stats64), and the other through the offset field of struct
ocelot_stat_layout elements (used for ethtool -S).
The strategy will be to keep the SYS_COUNT_* definitions as the single
source of truth, but for that we need to expand our current definitions
to cover all registers. Then we need to convert the ocelot region
creation logic, and stats worker, to the read semantics imposed by going
through SYS_COUNT_* absolute register addresses, rather than offsets
of 32-bit words relative to SYS_COUNT_RX_OCTETS (which should have been
SYS_CNT, by the way).

The ocelot counters are 32-bit and require periodic reading, every 2
seconds, by ocelot_port_update_stats(), so that wraparounds are
detected.
Currently, the counters reported by ocelot_get_stats64() come from the
32-bit hardware counters directly, rather than from the 64-bit
accumulated ocelot->stats, and this is a problem for their integrity.
The strategy is to make ocelot_get_stats64() able to cherry-pick
individual stats from ocelot->stats the way in which it currently reads
them out from SYS_COUNT_* registers. But currently it can't, because
ocelot->stats is an opaque u64 array that's used only to feed data into
ethtool -S.
To solve that problem, we need to make ocelot->stats indexable, and
associate each element with an element of struct ocelot_stat_layout used
by ethtool -S.
This makes ocelot_stat_layout a fat (and possibly sparse) array, so we
need to change the way in which we access it. We no longer need
OCELOT_STAT_END as a sentinel, because we know the array's size
(OCELOT_NUM_STATS). We just need to skip the array elements that were
left unpopulated for the switch revision (ocelot, felix, seville).

ocelot_get_stats64() currently runs unlocked and therefore may collide
with ocelot_port_update_stats() which indirectly accesses the same
counters. However, ocelot_get_stats64() runs in atomic context, and we
cannot simply take the sleepable ocelot->stats_lock mutex. We need to
convert it to an atomic spinlock first. Do that as a preparatory change.

Reading stats using the SYS_COUNT_* register definitions is only used by
ocelot_get_stats64() from the ocelot switchdev driver, however,
currently the bucket definitions are incorrect.
Separately, on both RX and TX, we have the following problems:
- a 256-1023 bucket which actually tracks the 256-511 packets
- the 1024-1526 bucket actually tracks the 512-1023 packets
- the 1527-max bucket actually tracks the 1024-1526 packets
=> nobody tracks the packets from the real 1527-max bucket
Additionally, the RX_PAUSE, RX_CONTROL, RX_LONGS and RX_CLASSIFIED_DROPS
all track the wrong thing. However this doesn't seem to have any
consequence, since ocelot_get_stats64() doesn't use these.
Even though this problem only manifests itself for the switchdev driver,
we cannot split the fix for ocelot and for DSA, since it requires fixing
the bucket definitions from enum ocelot_reg, which makes us necessarily
adapt the structures from felix and seville as well.

====================
netfilter: conntrack and nf_tables bug fixes
The following patchset contains netfilter fixes for net.
Broken since 5.19:
A few ancient connection tracking helpers assume TCP packets cannot
exceed 64kb in size, but this isn't the case anymore with 5.19 when
BIG TCP got merged, from myself.
Regressions since 5.19:
1. 'conntrack -E expect' won't display anything because nfnetlink failed
to enable events for expectations, only for normal conntrack events.
2. partially revert change that added resched calls to a function that can
be in atomic context. Both broken and fixed up by myself.
Broken for several releases (up to original merge of nf_tables):
Several fixes for nf_tables control plane, from Pablo.
This fixes up resource leaks in error paths and adds more sanity
checks for mutually exclusive attributes/flags.
Kconfig:
NF_CONNTRACK_PROCFS is very old and doesn't provide all info provided
via ctnetlink, so it should not default to y. From Geert Uytterhoeven.
Selftests:
rework nft_flowtable.sh: it frequently indicated failure; the way it
tried to detect an offload failure did not work reliably.
* git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf:
testing: selftests: nft_flowtable.sh: rework test to detect offload failure
testing: selftests: nft_flowtable.sh: use random netns names

bpf_sk_reuseport_detach() calls __rcu_dereference_sk_user_data_with_flags()
to obtain the value of sk->sk_user_data, but that function is only usable
if the RCU read lock is held, and neither that function nor any of its
callers hold it.
Fix this by adding a new helper, __locked_read_sk_user_data_with_flags()
that checks to see if sk->sk_callback_lock() is held and use that here
instead.
Alternatively, making __rcu_dereference_sk_user_data_with_flags() use
rcu_dereference_checked() might suffice.
Without this, the following warning can be occasionally observed:

These operations are documented as always ordered in
include/asm-generic/bitops/instrumented-atomic.h, and producer-consumer
type use cases where one side needs to ensure a flag is left pending
after some shared data was updated rely on this ordering, even in the
failure case.
This is the case with the workqueue code, which currently suffers from a
reproducible ordering violation on Apple M1 platforms (which are
notoriously out-of-order) that ends up causing the TTY layer to fail to
deliver data to userspace properly under the right conditions. This
change fixes that bug.
Change the documentation to restrict the "no order on failure" story to
the _lock() variant (for which it makes sense), and remove the
early-exit from the generic implementation, which is what causes the
missing barrier semantics in that case. Without this, the remaining
atomic op is fully ordered (including on ARM64 LSE, as of recent
versions of the architecture spec).

This reverts commit a10fba0377145fccefea4dc4dd5915b7ed87e546: the
proposed API isn't supported on all transports but no
effort was made to address this.
It might not be hard to fix if we want to: maybe just
rename size to size_hint and make sure legacy
transports ignore the hint.
But it's not sure what the benefit is in any case, so
let's drop it.

In the uniprocessor case, cpumask_next_wrap() can be simplified, as the
number of valid argument combinations is limited:
- 'start' can only be 0
- 'n' can only be -1 or 0
The only valid CPU that can then be returned, if any, will be the first
one set in the provided 'mask'.
For NR_CPUS == 1, include/linux/cpumask.h now provides an inline
definition of cpumask_next_wrap(), which will conflict with the one
provided by lib/cpumask.c. Make building of lib/cpumask.o again depend
on CONFIG_SMP=y (i.e. NR_CPUS > 1) to avoid the re-definition.

Right now we have a neigh_param PROXY_QLEN which specifies maximum length
of neigh_table->proxy_queue. But in fact, this limitation doesn't work well
because check condition looks like:
tbl->proxy_queue.qlen > NEIGH_VAR(p, PROXY_QLEN)
The problem is that p (struct neigh_parms) is a per-device thing,
but tbl (struct neigh_table) is a system-wide global thing.
It seems reasonable to make proxy_queue limit per-device based.

This is a size sensitive structure and randomizing can introduce extra
padding that breaks io_uring's fixed size expectations. There are few

Implement support for the HVMOP_set_evtchn_upcall_vector hypercall in
order to set the per-vCPU event channel vector callback on Linux and
use it in preference of HVM_PARAM_CALLBACK_IRQ.
If the per-VCPU vector setup is successful on BSP, use this method
for the APs. If not, fallback to the global vector-type callback.
Also register callback_irq at per-vCPU event channel setup to trick
toolstack to think the domain is enlightened.

"Including fixes from bluetooth, bpf, can and netfilter.
A little larger than usual but it's all fixes, no late features. It's
large partially because of timing, and partially because of follow ups
to stuff that got merged a week or so before the merge window and
wasn't as widely tested. Maybe the Bluetooth fixes are a little
alarming so we'll address that, but the rest seems okay and not scary.
Notably we're including a fix for the netfilter Kconfig [1], your WiFi

Current release - regressions:
- Bluetooth:
- don't try to cancel uninitialized works [3]
- L2CAP: fix use-after-free caused by l2cap_chan_put
- tls: rx: fix device offload after recent rework
- devlink: fix UAF on failed reload and leftover locks in mlxsw
Current release - new code bugs:
- netfilter:
- flowtable: fix incorrect Kconfig dependencies [1]
- nf_tables: fix crash when nf_trace is enabled
- bpf:
- use proper target btf when exporting attach_btf_obj_id
- arm64: fixes for bpf trampoline support
- Bluetooth:
- ISO: unlock on error path in iso_sock_setsockopt()
- ISO: fix info leak in iso_sock_getsockopt()
- ISO: fix iso_sock_getsockopt for BT_DEFER_SETUP
- ISO: fix memory corruption on iso_pinfo.base
- ISO: fix not using the correct QoS
- hci_conn: fix updating ISO QoS PHY
- phy: dp83867: fix get nvmem cell fail
Previous releases - regressions:
- wifi: cfg80211: fix validating BSS pointers in
__cfg80211_connect_result [2]
- atm: bring back zatm uAPI after ATM had been removed
- properly fix old bug making bonding ARP monitor mode not being able
to work with software devices with lockless Tx
- tap: fix null-deref on skb->dev in dev_parse_header_protocol
- revert "net: usb: ax88179_178a needs FLAG_SEND_ZLP" it helps some
devices and breaks others
- netfilter:
- nf_tables: many fixes rejecting cross-object linking which may
lead to UAFs
- nf_tables: fix null deref due to zeroed list head
- nf_tables: validate variable length element extension
- bgmac: fix a BUG triggered by wrong bytes_compl
- bcmgenet: indicate MAC is in charge of PHY PM
Previous releases - always broken:
- bpf:
- fix bad pointer deref in bpf_sys_bpf() injected via test infra
- disallow non-builtin bpf programs calling the prog_run command
- don't reinit map value in prealloc_lru_pop
- fix UAFs during the read of map iterator fd
- fix invalidity check for values in sk local storage map
- reject sleepable program for non-resched map iterator

"These fix up direct references to the fwnode field in struct device
and extend ACPI device properties support.
Specifics:
- Replace direct references to the fwnode field in struct device with
dev_fwnode() and device_match_fwnode() (Andy Shevchenko)
- Make the ACPI code handling device properties support properties
with buffer values (Sakari Ailus)"
