scsi: mpi3mr: Replace 1-element array with flex-array
Nothing else defined MPI3_NVME_ENCAP_CMD_MAX, so the "command" buffer was
being defined as a fake flexible array of size 1. Replace this with a
proper flex array. Avoids this GCC 13 warning under -fstrict-flex-arrays=3:

scsi: ipr: Work around fortify-string warning
The ipr_log_vpd_compact() function triggers a fortified memcpy() warning
about a potential string overflow with all versions of clang:
In file included from drivers/scsi/ipr.c:43:
In file included from include/linux/string.h:254:
include/linux/fortify-string.h:520:4: error: call to '__write_overflow_field' declared with 'warning' attribute: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Werror,-Wattribute-warning]
__write_overflow_field(p_size_field, size);
^
include/linux/fortify-string.h:520:4: error: call to '__write_overflow_field' declared with 'warning' attribute: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Werror,-Wattribute-warning]
2 errors generated.
I don't see anything actually wrong with the function, but this is the only
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.

scsi: ipr: Make ipr_probe_ioa_part2() return void
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.

scsi: sd: Update DIX config every time sd_revalidate_disk() is called
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: [142829.032340] hisi_sas_v3_hw 0000:b4:04.0: erroneous completion iptt=2375 task=00000000bea0970c dev id=5 direct-attached phy4 addr=51c20dbaf642a000 CQ hdr: 0x1023 0x50947 0x0 0x20000 Error info: 0x0 0x0 0x4 0x0 [142829.073883] sas: Enter sas_scsi_recover_host busy: 1 failed: 1 [142829.079783] sas: sas_scsi_find_task: aborting task 0x00000000bea0970c [142829.102342] sas: Internal abort: task to dev 51c20dbaf642a000 response: 0x0 status 0x5 [142829.110319] sas: sas_eh_handle_sas_errors: task 0x00000000bea0970c is done [142829.117275] sd 7:0:5:0: [sdc] tag#2375 UNKNOWN(0x2003) Result: hostbyte=0x05 driverbyte=DRIVER_OK cmd_age=0s [142829.127171] sd 7:0:5:0: [sdc] tag#2375 CDB: opcode=0x2a 2a 00 00 00 00 00 00 00 08 00 [142829.135059] I/O error, dev sdc, sector 0 op 0x1:(WRITE) flags 0x18800 phys_seg 1 prio class 2 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.

Networking changes for 6.3.
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.

riscv: Avoid enabling interrupts in die()
While working on something else, I noticed that the kernel would start
accepting interrupts again after crashing in an interrupt handler. Since
the kernel is already in inconsistent state, enabling interrupts is
dangerous and opens up risk of kernel state deteriorating further.
Interrupts do get enabled via what looks like an unintended side effect of
spin_unlock_irq, so switch to the more cautious
spin_lock_irqsave/spin_unlock_irqrestore instead.

riscv: jump_label: Fixup unaligned arch_static_branch function
Runtime code patching must be done at a naturally aligned address, or we
may execute on a partial instruction.
We have encountered problems traced back to static jump functions during
the test. We switched the tracer randomly for every 1~5 seconds on a
dual-core QEMU setup and found the kernel sucking at a static branch
where it jumps to itself.
The reason is that the static branch was 2-byte but not 4-byte aligned.
Then, the kernel would patch the instruction, either J or NOP, with two
half-word stores if the machine does not have efficient unaligned
accesses. Thus, moments exist where half of the NOP mixes with the other
half of the J when transitioning the branch. In our particular case, on
a little-endian machine, the upper half of the NOP was mixed with the
lower part of the J when enabling the branch, resulting in a jump that
jumped to itself. Conversely, it would result in a HINT instruction when
disabling the branch, but it might not be observable.
ARM64 does not have this problem since all instructions must be 4-byte
aligned.

RISC-V: Only provide the single-letter extensions in HWCAP

scripts/decodecode: Add support for RISC-V
RISC-V has some GNU disassembly quirks, e.g. it requires '-D' to
properly disassemble .2byte directives similar to Arm [1]. Further,
GNU objdump groups RISC-V instruction by 2 or 4 byte chunks, instead
doing byte-for-byte.
Add the required switches, and translate from short/word to bytes when
ARCH is "riscv".
An example how to invoke decodecode for RISC-V:
$ echo 'Code: bf45 f793 1007 f7d9 50ef 37af d541 b7d9 7097 00c8 (80e7)

riscv: lds: define RUNTIME_DISCARD_EXIT
riscv discards .exit.* sections at run-time but doesn't define RUNTIME_DISCARD_EXIT. However, the .exit.* sections are still allocated and kept even if the generic DISCARDS would discard the sections due to missing RUNTIME_DISCARD_EXIT, because the DISCARD sits at the end of the linker script. Add the missing RUNTIME_DISCARD_EXIT define so that it still works if we move DISCARD up or even at the beginning of the linker script.

netfilter: ctnetlink: make event listener tracking global
pernet tracking doesn't work correctly because other netns might have
set NETLINK_LISTEN_ALL_NSID on its event socket.
In this case its expected that events originating in other net
namespaces are also received.
Making pernet-tracking work while also honoring NETLINK_LISTEN_ALL_NSID
requires much more intrusive changes both in netlink and nfnetlink,
f.e. adding a 'setsockopt' callback that lets nfnetlink know that the
event socket entered (or left) ALL_NSID mode.
Move to global tracking instead: if there is an event socket anywhere
on the system, all net namespaces which have conntrack enabled and
use autobind mode will allocate the ecache extension.
netlink_has_listeners() returns false only if the given group has no
subscribers in any net namespace, the 'net' argument passed to
nfnetlink_has_listeners is only used to derive the protocol (nfnetlink),
it has no other effect.
For proper NETLINK_LISTEN_ALL_NSID-aware pernet tracking of event
listeners a new netlink_has_net_listeners() is also needed.

netfilter: xt_length: use skb len to match in length_mt6
For IPv6 Jumbo packets, the ipv6_hdr(skb)->payload_len is always 0, and its real payload_len ( > 65535) is saved in hbh exthdr. With 0 length for the jumbo packets, it may mismatch. To fix this, we can just use skb->len instead of parsing exthdrs, as the hbh exthdr parsing has been done before coming to length_mt6 in ip6_rcv_core() and br_validate_ipv6() and also the packet has been trimmed according to the correct IPv6 (ext)hdr length there, and skb len is trustable in length_mt6(). Note that this patch is especially needed after the IPv6 BIG TCP was supported in kernel, which is using IPv6 Jumbo packets. Besides, to match the packets greater than 65535 more properly, a v1 revision of xt_length may be needed to extend "min, max" to u32 in the future, and for now the IPv6 Jumbo packets can be matched by: # ip6tables -m length ! --length 0:65535 Fixes: |

bootconfig: Default BOOT_CONFIG_FORCE to y if BOOT_CONFIG_EMBED
When a kernel is built with CONFIG_BOOT_CONFIG_EMBED=y, the intention will normally be to unconditionally provide the specified kernel-boot arguments to the kernel, as opposed to requiring a separately provided bootconfig parameter. Therefore, make the BOOT_CONFIG_FORCE Kconfig option default to y in kernels built with CONFIG_BOOT_CONFIG_EMBED=y. The old semantics may be obtained by manually overriding this default.

Instead of cleaning the entire loaded kernel image to the PoC and disabling the MMU and caches before branching to the kernel bare metal entry point, leave the MMU and caches enabled and rely on EFI's cacheable 1:1 mapping of all of system RAM to populate the initial page tables. - Expose the AArch32 (compat) ELF_HWCAP features to user in an arm64 kernel (the arm32 kernel only defines the values). - Harden the arm64 shadow call stack pointer handling: stash the shadow stack pointer in the task struct on interrupt, load it directly from this structure. - Signal handling cleanups to remove redundant validation of size information and avoid reading the same data from userspace twice. - Refactor the hwcap macros to make use of the automatically generated ID registers. It should make new hwcaps writing less error prone. - Further arm64 sysreg conversion and some fixes. - arm64 kselftest fixes and improvements. - Pointer authentication cleanups: don't sign leaf functions, unify asm-arch manipulation. - Pseudo-NMI code generation optimisations. - Minor fixes for SME and TPIDR2 handling. - Miscellaneous updates: ARCH_FORCE_MAX_ORDER is now selectable, replace strtobool() to kstrtobool() in the cpufeature.c code, apply dynamic shadow call stack in two passes, intercept pfn changes in set_pte_at() without the required break-before-make sequence, attempt to dump all instructions on unhandled kernel faults. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE5RElWfyWxS+3PLO2a9axLQDIXvEFAmP0/QsACgkQa9axLQDI XvG+gA/+JDVEH9wRzAIZvbp9hSuohPc48xgAmIMP1eiVB0/5qeRjYAJwS33H0rXS BPC2kj9IBy/eQeM9ICg0nFd0zYznSVacITqe6NrqeJ1F+ftS4rrHdfxd+J7kIoCs V2L8e+BJvmHdhmNV2qMAgJdGlfxfQBA7fv2cy52HKYcouoOh1AUVR/x+yXVXAsCd qJP3+dlUKccgm/oc5unEC1eZ49u8O+EoasqOyfG6K5udMgzhEX3K6imT9J3hw0WT UjstYkx5uGS/prUrRCQAX96VCHoZmzEDKtQuHkHvQXEYXsYPF3ldbR2CziNJnHe7 QfSkjJlt8HAtExA+BkwEe9i0MQO/2VF5qsa2e4fA6l7uqGu3LOtS/jJd23C9n9fR Id8aBMeN6S8+MjqRA9L2uf4t6e4ISEHoG9ZRdc4WOwloxEEiJoIeun+7bHdOSZLj AFdHFCz4NXiiwC0UP0xPDI2YeCLqt5np7HmnrUqwzRpVO8UUagiJD8TIpcBSjBN9 J68eidenHUW7/SlIeaMKE2lmo8AUEAJs9AorDSugF19/ThJcQdx7vT2UAZjeVB3j 1dbbwajnlDOk/w8PQC4thFp5/MDlfst0htS3WRwa+vgkweE2EAdTU4hUZ8qEP7FQ smhYtlT1xUSTYDTqoaG/U2OWR6/UU79wP0jgcOsHXTuyYrtPI/Q= =VmXL -----END PGP SIGNATURE----- Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 updates from Catalin Marinas: - Support for arm64 SME 2 and 2.1.

Allow forcing unconditional bootconfig processing
The BOOT_CONFIG family of Kconfig options allows a bootconfig file containing kernel boot parameters to be embedded into an initrd or into the kernel itself. This can be extremely useful when deploying kernels in cases where some of the boot parameters depend on the kernel version rather than on the server hardware, firmware, or workload. Unfortunately, the "bootconfig" kernel parameter must be specified in order to cause the kernel to look for the embedded bootconfig file, and it clearly does not help to embed this "bootconfig" kernel parameter into that file. Therefore, provide a new BOOT_CONFIG_FORCE Kconfig option that causes the kernel to act as if the "bootconfig" kernel parameter had been specified. In other words, kernels built with CONFIG_BOOT_CONFIG_FORCE=y will look for the embedded bootconfig file even when the "bootconfig" kernel parameter is omitted. This permits kernel-version-dependent kernel boot parameters to be embedded into the kernel image without the need to (for example) update large numbers of boot loaders.

point, but its not.
t = find_table_lock(net, repl->name, &ret, &ebt_mutex);
... this can return a valid table, with ret != 0.
This bug causes update of table->private with the new

scsi: ufs: mcq: Fix incorrectly set queue depth
ufshcd_config_mcq() may change the can_queue value. The current code
invokes scsi_add_host() before ufshcd_config_mcq() so the tags are
limited to the original can_queue value.
Fix this by invoking scsi_add_host() after ufshcd_config_mcq().

netfilter: conntrack: fix rmmod double-free race
nf_conntrack_hash_check_insert() callers free the ct entry directly, via
nf_conntrack_free.
This isn't safe anymore because
nf_conntrack_hash_check_insert() might place the entry into the conntrack
table and then delteted the entry again because it found that a conntrack
extension has been removed at the same time.
In this case, the just-added entry is removed again and an error is
returned to the caller.
Problem is that another cpu might have picked up this entry and
incremented its reference count.
This results in a use-after-free/double-free, once by the other cpu and
once by the caller of nf_conntrack_hash_check_insert().
Fix this by making nf_conntrack_hash_check_insert() not fail anymore
after the insertion, just like before the 'Fixes' commit.
This is safe because a racing nf_ct_iterate() has to wait for us
to release the conntrack hash spinlocks.
While at it, make the function return -EAGAIN in the rmmod (genid
changed) case, this makes nfnetlink replay the command (suggested
by Pablo Neira).

scsi: ufs: core: Initialize devfreq synchronously
During UFS initialization, devfreq initialization is asynchronous: ufshcd_async_scan() calls ufshcd_add_lus(), which in turn initializes devfreq for UFS. The simple ondemand governor is then loaded. If it is built as a module, request_module() is called and throws a warning: WARNING: CPU: 7 PID: 167 at kernel/kmod.c:136 __request_module+0x1e0/0x460 Modules linked in: crct10dif_ce llcc_qcom phy_qcom_qmp_usb ufs_qcom phy_qcom_snps_femto_v2 ufshcd_pltfrm phy_qcom_qmp_combo ufshcd_core phy_qcom_qmp_ufs qcom_wdt socinfo fuse ipv6 CPU: 7 PID: 167 Comm: kworker/u16:3 Not tainted 6.2.0-rc6-00009-g58706f7fb045 #1 Hardware name: Qualcomm SA8540P Ride (DT) Workqueue: events_unbound async_run_entry_fn pstate: 00400005 (nzcv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc : __request_module+0x1e0/0x460 lr : __request_module+0x1d8/0x460 sp : ffff800009323b90 x29: ffff800009323b90 x28: 0000000000000000 x27: 0000000000000000 x26: ffff800009323d50 x25: ffff7b9045f57810 x24: ffff7b9045f57830 x23: ffffdc5a83e426e8 x22: ffffdc5ae80a9818 x21: 0000000000000001 x20: ffffdc5ae7502f98 x19: ffff7b9045f57800 x18: ffffffffffffffff x17: 312f716572667665 x16: 642f7366752e3030 x15: 0000000000000000 x14: 000000000000021c x13: 0000000000005400 x12: ffff7b9042ed7614 x11: ffff7b9042ed7600 x10: 00000000636c0890 x9 : 0000000000000038 x8 : ffff7b9045f2c880 x7 : ffff7b9045f57c68 x6 : 0000000000000080 x5 : 0000000000000000 x4 : 8000000000000000 x3 : 0000000000000000 x2 : 0000000000000000 x1 : ffffdc5ae5d382f0 x0 : 0000000000000001 Call trace: __request_module+0x1e0/0x460 try_then_request_governor+0x7c/0x100 devfreq_add_device+0x4b0/0x5fc ufshcd_async_scan+0x1d4/0x310 [ufshcd_core] async_run_entry_fn+0x34/0xe0 process_one_work+0x1d0/0x320 worker_thread+0x14c/0x444 kthread+0x10c/0x110 ret_from_fork+0x10/0x20 This occurs because synchronous module loading from async is not allowed. According to __request_module(): /* * We don't allow synchronous module loading from async. Module * init may invoke async_synchronize_full() which will end up * waiting for this task which already is waiting for the module * loading to complete, leading to a deadlock. */ Such a deadlock was experienced on the Qualcomm QDrive3/sa8540p-ride. With DEVFREQ_GOV_SIMPLE_ONDEMAND=m, the boot hangs after the warning. Fix both the warning and the deadlock by moving devfreq initialization out of the async routine. Tested on the sa8540p-ride by using fio to put the UFS under load, and printing the trace generated by /sys/kernel/tracing/events/ufs/ufshcd_clk_scaling events. The trace looks similar with and without the change.

s390 updates for 6.3 merge window
- Large cleanup of the con3270/tty3270 driver. Among others this fixes:
* Background Color Support
* ASCII Line Character Support
* VT100 Support
* Geometries other than 80x24
- Cleanup and improve cmpxchg() code. Also add cmpxchg_user_key() to
uaccess functions, which will be used by KVM to access KVM guest memory
with a specific storage key.
- Add support for user space events counting to CPUMF.
- Cleanup the vfio/ccw code, which also allows now to properly support 2K
Format-2 IDALs.
- Move kernel page table allocation and initialization to decompressor,
which finally allows to enter the kernel with dynamic address translation
enabled. This in turn allows to get rid of code with special handling in
the kernel, which has to distinguish if DAT is on or off.
- Replace kretprobe with rethook.
- Various improvements to vfio/ap queue resets:
* Use TAPQ to verify completion of a reset in progress rather than
multiple invocations of ZAPQ.
* Check TAPQ response codes when verifying successful completion of ZAPQ.
* Fix erroneous handling of some error response codes.
* Increase the maximum amount of time to wait for successful completion
of ZAPQ.
- Rework system call wrappers to get rid of alias functions, which were
only left on s390.
- Cleanup diag288_wdt watchdog driver. It has been agreed on with Guenter
Roeck that this goes upstream via the s390 tree.
- Add missing loadparm parameter handling for list-directed ECKD ipl/reipl.
- Various improvements to memory detection code.
- Remove arch_cpu_idle_time() since the current implementation is broken,
and allows user space observable accounted idle times which can
temporarily decrease.
- Add Reset DAT-Protection support: (only) allow to change PTEs from RO to
RW with a new RDP instruction. Unlike the currently used IPTE
instruction, this does not necessarily guarantee that TLBs of all CPUs
are synchronously flushed; and that remote CPUs can see spurious
protection faults. The overall improvement for not requiring an all CPU
synchronization, like it is required with IPTE, should be beneficial.
- Fix KFENCE page fault reporting.
- Smaller cleanups and improvement all over the place.
