Pull driver core updates from Greg KH:
"Here is the large set of driver core changes for 6.3-rc1.
There's a lot of changes this development cycle, most of the work
falls into two different categories:
- fw_devlink fixes and updates. This has gone through numerous review
cycles and lots of review and testing by lots of different devices.
Hopefully all should be good now, and Saravana will be keeping a
watch for any potential regression on odd embedded systems.
- driver core changes to work to make struct bus_type able to be
moved into read-only memory (i.e. const) The recent work with Rust
has pointed out a number of areas in the driver core where we are
passing around and working with structures that really do not have
to be dynamic at all, and they should be able to be read-only
making things safer overall. This is the contuation of that work
(started last release with kobject changes) in moving struct
bus_type to be constant. We didn't quite make it for this release,
but the remaining patches will be finished up for the release after
this one, but the groundwork has been laid for this effort.
Other than that we have in here:
- debugfs memory leak fixes in some subsystems
- error path cleanups and fixes for some never-able-to-be-hit
codepaths.
- cacheinfo rework and fixes
- Other tiny fixes, full details are in the shortlog
All of these have been in linux-next for a while with no reported
problems"
[ Geert Uytterhoeven points out that that last sentence isn't true, and
that there's a pending report that has a fix that is queued up - Linus ]

Pull ATA updates from Damien Le Moal:
- Small cleanup of the pata_octeon driver to drop a useless platform
callback (Uwe)
- Simplify ata_scsi_cmd_error_handler() code using the fact that
ap->ops->error_handler is NULL most of the time (Wenchao)
- Several patches improving libata error handling. This is in
preparation for supporting the command duration limits (CDL) feature.
The changes allow handling corner cases of ATA NCQ errors which do
not happen with regular drives but will be triggered with CDL drives
(Niklas)
- Simplify the qc_fill_rtf operation (me)
- Improve SCSI command translation for REPORT_SUPPORTED_OPERATION_CODES
command (me)
- Cleanup of libata FUA handling.
This falls short of enabling FUA for ATA drives that support it by
default as there were concerns that old drives would break. The
series however fixes several issues with the FUA support to ensure
that FUA is reported as being supported only for drives that can
handle all possible write cases (NCQ and non-NCQ). A check in the
block layer is also added to ensure that we never see read FUA
commands (current behavior) (me)
- Several patches to move the old PARIDE (parallel port IDE) driver to
libata as pata_parport. Given that this driver also needs protocol
modules, the driver code resides in its own pata_parport directoy
under drivers/ata (Ondrej)

Commit c1af985d27da ("scsi: mpi3mr: Add Event acknowledgment logic")
introduced an array mrioc->evtack_cmds but initialization of the array
elements was missed. They are just zero cleared. The function
mpi3mr_complete_evt_ack() refers host_tag field of the elements. Due to the
zero value of the host_tag field, the function calls clear_bit() for
mrico->evtack_cmds_bitmap with wrong bit index. This results in memory
access to invalid address and "BUG: KASAN: use-after-free". This BUG was
observed at eHBA-9600 firmware update to version 8.3.1.0. To fix it, add
the missing initialization of mrioc->evtack_cmds.

To allocate bitmaps, the mpi3mr driver calculates sizes of bitmaps using
byte as unit. However, bitmap helper functions assume that bitmaps are
allocated using unsigned long as unit. This gap causes memory access beyond
the bitmap sizes and results in "BUG: KASAN: slab-out-of-bounds". The BUG
was observed at firmware download to eHBA-9600. Call trace indicated that
the out-of-bounds access happened in find_first_zero_bit() called from
mpi3mr_send_event_ack() for miroc->evtack_cmds_bitmap.
To fix the BUG, do not use bytes to manage bitmap sizes. Instead, use
number of bits, and call bitmap helper functions which take number of bits
as arguments. For memory allocation, call bitmap_zalloc() instead of
kzalloc() and krealloc(). For memory free, call bitmap_free() instead of
kfree(). For zero clear, call bitmap_clear() instead of memset().
Remove three fields for bitmap byte sizes in struct scmd_priv which are no
longer required. Replace the field dev_handle_bitmap_sz with
dev_handle_bitmap_bits to keep number of bits of removepend_bitmap across
resize.

In the function mpi3mr_get_all_tgt_info(), devmap_info points to
alltgt_info->dmi then there is no need to memcpy() data from devmap_info to
alltgt_info->dmi. Remove the unnecessary memcpy(). This also allows to
remove the local variable 'rval' and the goto label 'out'.

The function mpi3mr_get_all_tgt_info() has four issues:
1) It calculates valid entry length in alltgt_info assuming the header part
of the struct mpi3mr_device_map_info would equal to sizeof(u32). The
correct size is sizeof(u64).
2) When it calculates the valid entry length kern_entrylen, it excludes one
entry by subtracting 1 from num_devices.
3) It copies num_device by calling memcpy(). Substitution is enough.
4) It does not specify the calculated length to sg_copy_from_buffer().
Instead, it specifies the payload length which is larger than the
alltgt_info size. It causes "BUG: KASAN: slab-out-of-bounds".
Fix the issues by using the correct header size, removing the subtraction
from num_devices, replacing the memcpy() with substitution and specifying
the correct length to sg_copy_from_buffer().

instance I can reproduce of the fortification going wrong in the kernel at
the moment, so the easiest solution may be to rewrite the function into
something that does not trigger the warning.
Instead of having a combined buffer for vendor/device/serial strings, use
three separate local variables and just truncate the whitespace
individually.

Convert function ipr_probe_ioa_part2() to return void instead of int since
the current implementation always returns 0 to the caller. The
transformation also eliminates the dead code when calling
ipr_probe_ioa_part2() function. Issue identified using returnvar
Coccinelle semantic patch.

If a controller has DIX is enabled and an attached disk is formatted using
a protection type supported by the controller, a block integrity profile is
registered to enable protected transfers.
If the disk is subsequently reformatted to disable PI, and the controller
does not support DIX Type 0, this can lead to failures such as this:

This is because the block layer integrity profile is currently only set up
the first time a disk is discovered.
To address this, remove the first_scan check when configuring protection
information during revalidate. Also unregister the block integrity profile
if DIX is not supported with a given protection type.

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Jakub Kicinski:
"Core:
- Add dedicated kmem_cache for typical/small skb->head, avoid having
to access struct page at kfree time, and improve memory use.
- Introduce sysctl to set default RPS configuration for new netdevs.
- Define Netlink protocol specification format which can be used to
describe messages used by each family and auto-generate parsers.
Add tools for generating kernel data structures and uAPI headers.
- Expose all net/core sysctls inside netns.
- Remove 4s sleep in netpoll if carrier is instantly detected on
boot.
- Add configurable limit of MDB entries per port, and port-vlan.
- Continue populating drop reasons throughout the stack.
- Retire a handful of legacy Qdiscs and classifiers.
Protocols:
- Support IPv4 big TCP (TSO frames larger than 64kB).
- Add IP_LOCAL_PORT_RANGE socket option, to control local port range
on socket by socket basis.
- Track and report in procfs number of MPTCP sockets used.
- Support mixing IPv4 and IPv6 flows in the in-kernel MPTCP path
manager.
- IPv6: don't check net.ipv6.route.max_size and rely on garbage
collection to free memory (similarly to IPv4).
- Support Penultimate Segment Pop (PSP) flavor in SRv6 (RFC8986).
- ICMP: add per-rate limit counters.
- Add support for user scanning requests in ieee802154.
- Remove static WEP support.
- Support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate
reporting.
- WiFi 7 EHT channel puncturing support (client & AP).
BPF:
- Add a rbtree data structure following the "next-gen data structure"
precedent set by recently added linked list, that is, by using
kfunc + kptr instead of adding a new BPF map type.
- Expose XDP hints via kfuncs with initial support for RX hash and
timestamp metadata.
- Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key to
better support decap on GRE tunnel devices not operating in collect
metadata.
- Improve x86 JIT's codegen for PROBE_MEM runtime error checks.
- Remove the need for trace_printk_lock for bpf_trace_printk and
bpf_trace_vprintk helpers.
- Extend libbpf's bpf_tracing.h support for tracing arguments of
kprobes/uprobes and syscall as a special case.
- Significantly reduce the search time for module symbols by
livepatch and BPF.
- Enable cpumasks to be used as kptrs, which is useful for tracing
programs tracking which tasks end up running on which CPUs in
different time intervals.
- Add support for BPF trampoline on s390x and riscv64.
- Add capability to export the XDP features supported by the NIC.
- Add __bpf_kfunc tag for marking kernel functions as kfuncs.
- Add cgroup.memory=nobpf kernel parameter option to disable BPF
memory accounting for container environments.
Netfilter:
- Remove the CLUSTERIP target. It has been marked as obsolete for
years, and we still have WARN splats wrt races of the out-of-band
/proc interface installed by this target.
- Add 'destroy' commands to nf_tables. They are identical to the
existing 'delete' commands, but do not return an error if the
referenced object (set, chain, rule...) did not exist.
Driver API:
- Improve cpumask_local_spread() locality to help NICs set the right
IRQ affinity on AMD platforms.
- Separate C22 and C45 MDIO bus transactions more clearly.
- Introduce new DCB table to control DSCP rewrite on egress.
- Support configuration of Physical Layer Collision Avoidance (PLCA)
Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of
shared medium Ethernet.
- Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing
preemption of low priority frames by high priority frames.
- Add support for controlling MACSec offload using netlink SET.
- Rework devlink instance refcounts to allow registration and
de-registration under the instance lock. Split the code into
multiple files, drop some of the unnecessarily granular locks and
factor out common parts of netlink operation handling.
- Add TX frame aggregation parameters (for USB drivers).
- Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning
messages with notifications for debug.
- Allow offloading of UDP NEW connections via act_ct.
- Add support for per action HW stats in TC.
- Support hardware miss to TC action (continue processing in SW from
a specific point in the action chain).
- Warn if old Wireless Extension user space interface is used with
modern cfg80211/mac80211 drivers. Do not support Wireless
Extensions for Wi-Fi 7 devices at all. Everyone should switch to
using nl80211 interface instead.
- Improve the CAN bit timing configuration. Use extack to return
error messages directly to user space, update the SJW handling,
including the definition of a new default value that will benefit
CAN-FD controllers, by increasing their oscillator tolerance.

The LLDD and the stack currently process FPINs received from the fabric,
but the stack is not aware of any action taken by the driver to alleviate
congestion. The current interface between the driver and the SCSI stack is
limited to passing the notification mainly for statistics and heuristics.
The reaction to an FPIN could be handled either by the driver or by the
stack (marginal path and failover). Amend the interface to indicate if
action on an FPIN has already been reacted to by the LLDDs or not. Add an
additional flag to fc_host_fpin_rcv() to indicate if the FPIN has been
acknowledged/reacted to by the driver.
Also added a new event code FCH_EVT_LINK_FPIN_ACK to notify to the user
that the event has been acknowledged/reacted by the LLDD driver

An enclosure with no components can't usefully be operated by the driver
(since effectively it has nothing to manage), so report the problem and
don't attach. Not attaching also fixes an oops which could occur if the
driver tries to manage a zero component enclosure.

When calling debugfs_lookup() the result must have dput() called on it,
otherwise the memory will leak over time. To make things simpler, just
call debugfs_lookup_and_remove() instead which handles all of the logic at
once.

SCSI_SCAN_TARGET_PRESENT"
This reverts commit 948e922fc44611ee2de0c89583ca958cb5307d36.
Not all targets that return PQ=1 and PDT=0 should be ignored. While
the SCSI spec is vague in this department, there appears to be a
critical mass of devices which rely on devices being accessible with
this combination of reported values.

Although most calls of scsi_device_put() happen from non-atomic context,
alua_rtpg_queue() calls this function from atomic context if
alua_rtpg_queue() itself is called from atomic context. alua_rtpg_queue()
is always called from contexts where the caller must hold at least one
reference to the scsi device in question. This means that the reference
taken by alua_rtpg_queue() itself can't be the last one, and thus can be
dropped without entering the code path in which scsi_device_put() might
actually sleep. Hence move the might_sleep() annotation from
scsi_device_put() into scsi_device_dev_release().
