tracing: Replace strlcpy with strscpy in trace/events/task.h
strlcpy() reads the entire source buffer first. This read may exceed the destination size limit. This is both inefficient and can lead to linear read overflows if a source string is not NUL-terminated [1]. In an effort to remove strlcpy() completely [2], replace strlcpy() here with strscpy(). No return values were used, so direct replacement is safe.

NFSD 6.6 Release Notes
I'm thrilled to announce that the Linux in-kernel NFS server now offers NFSv4 write delegations. A write delegation enables a client to cache data and metadata for a single file more aggressively, reducing network round trips and server workload. Many thanks to Dai Ngo for contributing this facility, and to Jeff Layton and Neil Brown for reviewing and testing it. This release also sees the removal of all support for DES- and triple-DES-based Kerberos encryption types in the kernel's SunRPC implementation. These encryption types have been deprecated by the Internet community for years and are considered insecure. This change affects both the in-kernel NFS client and server. The server's UDP and TCP socket transports have now fully adopted David Howells' new bio_vec iterator so that no more than one sendmsg() call is needed to transmit each RPC message. In particular, this helps kTLS optimize record boundaries when sending RPC-with-TLS replies, and it takes the server a baby step closer to handling file I/O via folios. We've begun work on overhauling the SunRPC thread scheduler to remove a costly linked-list walk when looking for an idle RPC service thread to wake. The pre-requisites are included in this release. Thanks to Neil Brown for his ongoing work on this improvement. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEKLLlsBKG3yQ88j7+M2qzM29mf5cFAmTwoa0ACgkQM2qzM29m f5cZvw/8CmFVNC27aMrJEhRRhwwrXbLzUkWh9GCYkG98PHYiLxLTvZ6qELXAax/a UjSgIDSRcWl4z8M/tyBQtgsw7NADr+7XWqEoXR7HZ5pEEC/KNGM0oQWQ92ojjKYy JmHdB02uaDJfcd9ioFTU13cw7q2BQfoe2xLI8yqis2vcVSu92AM7aIw+cvJIpwQB inA3TIIsYTV/gPByXSfEtvmYACadoFiMvfvYwaWhjFS9MdSzFmcVG0Dp3EFIig29 odmWEofcz6uIvUWvUswWEGdoSu7uOKIztSuAI4PlTwaofUaSKG6e5kmtpr3cLERD Uhg2lm5JgqkXBd7QHObNimJ4DtQzFwHmhA08qo8rd/zba75mn/Hr5IF0q3Rxs99J SRYHcAeP8afKn5Ge0yzoTgCNcqhfz8KLRfoCQX49mljr+muNxld4nMklD2KdUwJi XEB512/q3E4nUgopXZiSJYQYAq1CfdR5WpGipZ9X0XK9HZBDF/qhXGtk1YQuNWyj ZxJS3bfBza4oVIvP5/ehjCIQwOvqkcrC5zZGDIgDvw9Q6L3L1wqmVntsdCLCLRcJ jB4IOsj+DECfJ6w2vP2SZ3GeMtFnyuTQjhUTkjPuAKTBBiKo4Tj0o/agpfDYbWZy 1l3a2yH5jqJgkm4MaVh3YHRJGc0ub0ccpIrs3QQ4jvjMLQ/3Gcs= =XGHs -----END PGP SIGNATURE----- Merge tag 'nfsd-6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux Pull nfsd updates from Chuck Lever: "I'm thrilled to announce that the Linux in-kernel NFS server now offers NFSv4 write delegations.

SUNRPC: Move trace_svc_xprt_enqueue
The xpt_flags field frequently changes between the time that svc_xprt_ready() grabs a copy and execution flow arrives at the tracepoint at the tail of svc_xprt_enqueue(). In fact, there's usually a sleep/wake-up in there, so those flags are almost guaranteed to be different. It would be more useful to record the exact flags that were used to decide whether the transport is ready, so move the tracepoint. Moving it means the tracepoint can't pick up the waker's pid. That can be added to struct svc_rqst if it turns out that is important. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> |

SUNRPC: Add enum svc_auth_status
In addition to the benefits of using an enum rather than a set of macros, we now have a named type that can improve static type checking of function return values. As part of this change, I removed a stale comment from svcauth.h; the return values from current implementations of the auth_ops::release method are all zero/negative errno, not the SVC_OK enum values as the old comment suggested.

SUNRPC: change svc_xprt::xpt_flags bits to enum
When a sequence of numbers are needed for internal-use only, an enum is typically best. The sequence will inevitably need to be changed one day, and having an enum means the developer doesn't need to think about renumbering after insertion or deletion. Such patches will be easier to review. Suggested-by: NeilBrown <neilb@suse.de> Signed-off-by: Chuck Lever <chuck.lever@oracle.com> |

- Refactor nexthop selection for multipath routes.
- Improve sched class lifetime handling.
- Add backup nexthop ID support for bridge.
- Implement drop reasons support in openvswitch.
- Several data races annotations and fixes.
- Constify the sk parameter of routing functions.
- Prepend kernel version to netconsole message.
Protocols
---------
- Implement support for TCP probing the peer being under memory
pressure.
- Remove hard coded limitation on IPv6 specific info placement
inside the socket struct.
- Get rid of sysctl_tcp_adv_win_scale and use an auto-estimated
per socket scaling factor.
- Scaling-up the IPv6 expired route GC via a separated list of
expiring routes.
- In-kernel support for the TLS alert protocol.
- Better support for UDP reuseport with connected sockets.
- Add NEXT-C-SID support for SRv6 End.X behavior, reducing the SR
header size.
- Get rid of additional ancillary per MPTCP connection struct socket.
- Implement support for BPF-based MPTCP packet schedulers.
- Format MPTCP subtests selftests results in TAP.
- Several new SMC 2.1 features including unique experimental options,
max connections per lgr negotiation, max links per lgr negotiation.
BPF
---
- Multi-buffer support in AF_XDP.
- Add multi uprobe BPF links for attaching multiple uprobes
and usdt probes, which is significantly faster and saves extra fds.
- Implement an fd-based tc BPF attach API (TCX) and BPF link support on
top of it.
- Add SO_REUSEPORT support for TC bpf_sk_assign.
- Support new instructions from cpu v4 to simplify the generated code and
feature completeness, for x86, arm64, riscv64.
- Support defragmenting IPv(4|6) packets in BPF.
- Teach verifier actual bounds of bpf_get_smp_processor_id()
and fix perf+libbpf issue related to custom section handling.
- Introduce bpf map element count and enable it for all program types.
- Add a BPF hook in sys_socket() to change the protocol ID
from IPPROTO_TCP to IPPROTO_MPTCP to cover migration for legacy.
- Introduce bpf_me_mcache_free_rcu() and fix OOM under stress.
- Add uprobe support for the bpf_get_func_ip helper.
- Check skb ownership against full socket.
- Support for up to 12 arguments in BPF trampoline.
- Extend link_info for kprobe_multi and perf_event links.
Netfilter
---------
- Speed-up process exit by aborting ruleset validation if a
fatal signal is pending.
- Allow NLA_POLICY_MASK to be used with BE16/BE32 types.
Driver API
----------
- Page pool optimizations, to improve data locality and cache usage.
- Introduce ndo_hwtstamp_get() and ndo_hwtstamp_set() to avoid the need
for raw ioctl() handling in drivers.
- Simplify genetlink dump operations (doit/dumpit) providing them
the common information already populated in struct genl_info.
- Extend and use the yaml devlink specs to [re]generate the split ops.
- Introduce devlink selective dumps, to allow SF filtering SF based on
handle and other attributes.

spi: Updates for v6.6
There's been quite a lot of generic activity here, but more
administrative than featuers. We also have a bunch of new drivers,
including one that's part of a MFD so we pulled in the core parts of
that:
- Lots of work from both Yang Yingliang and Andy Shevchenko on moving
to host/device/controller based terminology for devices.
- QuadSPI SPI support for Allwinner sun6i.
- New device support Cirrus Logic CS43L43, Longsoon, Qualcomm GENI
QuPv3 and StarFive JH7110 QSPI.

Merge tag 'for-6.6-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs updates from David Sterba:
"No new features, the bulk of the changes are fixes, refactoring and
cleanups. The notable fix is the scrub performance restoration after
rewrite in 6.4, though still only partial.
Fixes:
- scrub performance drop due to rewrite in 6.4 partially restored:
- do IO grouping by blg_plug/blk_unplug again
- avoid unnecessary tree searches when processing stripes, in
extent and checksum trees
- the drop is noticeable on fast PCIe devices, -66% and restored
to -33% of the original
- backports to 6.4 planned
- handle more corner cases of transaction commit during orphan
cleanup or delayed ref processing
- use correct fsid/metadata_uuid when validating super block
- copy directory permissions and time when creating a stub subvolume
Core:
- debugging feature integrity checker deprecated, to be removed in
6.7
- in zoned mode, zones are activated just before the write, making
error handling easier, now the overcommit mechanism can be enabled
again which improves performance by avoiding more frequent flushing
- v0 extent handling completely removed, deprecated long time ago
- error handling improvements
- tests:
- extent buffer bitmap tests
- pinned extent splitting tests
- cleanups and refactoring:
- compression writeback
- extent buffer bitmap
- space flushing, ENOSPC handling"

btrfs: remove v0 extent handling
The v0 extent item has been deprecated for a long time, and we don't have any report from the community either. So it's time to remove the v0 extent specific error handling, and just treat them as regular extent tree corruption. This patch would remove the btrfs_print_v0_err() helper, and enhance the involved error handling to treat them just as any extent tree corruption. No reports regarding v0 extents have been seen since the graceful handling was added in 2018. This involves: - btrfs_backref_add_tree_node() This change is a little tricky, the new code is changed to only handle BTRFS_TREE_BLOCK_REF_KEY and BTRFS_SHARED_BLOCK_REF_KEY. But this is safe, as we have rejected any unknown inline refs through btrfs_get_extent_inline_ref_type(). For keyed backrefs, we're safe to skip anything we don't know (that's if it can pass tree-checker in the first place). - btrfs_lookup_extent_info() - lookup_inline_extent_backref() - run_delayed_extent_op() - __btrfs_free_extent() - add_tree_block() Regular error handling of unexpected extent tree item, and abort transaction (if we have a trans handle). - remove_extent_data_ref() It's pretty much the same as the regular rejection of unknown backref key. But for this particular case, we can also remove a BUG_ON(). - extent_data_ref_count() We can remove the BTRFS_EXTENT_REF_V0_KEY BUG_ON(), as it would be rejected by the only caller. - btrfs_print_leaf() Remove the handling for BTRFS_EXTENT_REF_V0_KEY.

kernel.h: split out COUNT_ARGS() and CONCATENATE() to args.h
Patch series "kernel.h: Split out a couple of macros to args.h", v4. There are macros in kernel.h that can be used outside of that header. Split them to args.h and replace open coded variants. This patch (of 4): kernel.h is being used as a dump for all kinds of stuff for a long time. The COUNT_ARGS() and CONCATENATE() macros may be used in some places without need of the full kernel.h dependency train with it. Here is the attempt on cleaning it up by splitting out these macros(). While at it, include new header where it's being used.

Anon transparent hugepage is not supported even though we do have helpers checking pud_trans_huge(). We should never find that return true. The only expected pte bit combination is _PAGE_PTE | _PAGE_DEVMAP. Some of the helpers are never expected to get called on hash translation and hence is marked to call BUG() in such a case.

net: invert the netdevice.h vs xdp.h dependency
xdp.h is far more specific and is included in only 67 other files vs netdevice.h's 1538 include sites. Make xdp.h include netdevice.h, instead of the other way around. This decreases the incremental allmodconfig builds size when xdp.h is touched from 5947 to 662 objects. Move bpf_prog_run_xdp() to xdp.h, seems appropriate and filter.h is a mega-header in its own right so it's nice to avoid xdp.h getting included there as well. The only unfortunate part is that the typedef for xdp_features_t has to move to netdevice.h, since its embedded in struct netdevice.

bpf, xdp: Add tracepoint to xdp attaching failure
When error happens in dev_xdp_attach(), it should have a way to tell users the error message like the netlink approach. To avoid breaking uapi, adding a tracepoint in bpf_xdp_link_attach() is an appropriate way to notify users the error message. Hence, bpf libraries are able to retrieve the error message by this tracepoint, and then report the error message to users.

blk-wbt: Replace strlcpy with strscpy
strlcpy() reads the entire source buffer first. This read may exceed the destination size limit. This is both inefficient and can lead to linear read overflows if a source string is not NUL-terminated [1]. In an effort to remove strlcpy() completely [2], replace strlcpy() here with strscpy().

f2fs update for 6.5-rc1
In this cycle, we've mainly investigated the zoned block device support along
with patches such as correcting write pointers between f2fs and storage, adding
asynchronous zone reset flow, and managing the number of open zones. Other than
them, f2fs adds another mount option, "errors=x" to specify how to handle when
it detects an unexpected behavior at runtime.
Enhancement:
- support errors=remount-ro|continue|panic mountoption
- enforce some inode flag policies
- allow .tmp compression given extensions
- add some ioctls to manage the f2fs compression
- improve looped node chain flow
- avoid issuing small-sized discard commands during checkpoint
- implement an asynchronous zone reset
Bug fix:
- fix deadlock in xattr and inode page lock
- fix and add sanity check in some error paths
- fix to avoid NULL pointer dereference f2fs_write_end_io() along with put_super
- set proper flags to quota files
- fix potential deadlock due to unpaired node_write lock use
- fix over-estimating free section during FG GC
- fix the wrong condition to determine atomic context
As usual, also there are a number of patches having code refactoring and minor
clean-ups.

NFS client updates for Linux 6.5
Highlights include:
Stable fixes and other bugfixes:
- nfs: don't report STATX_BTIME in ->getattr
- Revert "NFSv4: Retry LOCK on OLD_STATEID during delegation return"
since it breaks NFSv4 state recovery.
- NFSv4.1: freeze the session table upon receiving NFS4ERR_BADSESSION
- Fix the NFSv4.2 xattr cache shrinker_id
- Force a ctime update after a NFSv4.2 SETXATTR call
Features and cleanups:
- NFS and RPC over TLS client code from Chuck Lever.
- Support for use of abstract unix socket addresses with the rpcbind
daemon.
- Sysfs API to allow shutdown of the kernel RPC client and prevent
umount() hangs if the server is known to be permanently down.
- XDR cleanups from Anna.

SCSI misc on 20230629
Updates to the usual drivers (ufs, pm80xx, libata-scsi, smartpqi,
lpfc, qla2xxx). We have a couple of major core changes impacting
other systems: Command Duration Limits, which spills into block and
ATA and block level Persistent Reservation Operations, which touches
block, nvme, target and dm (both of which are added with merge commits
containing a cover letter explaining what's going on).

ext4: Give symbolic names to mballoc criterias
mballoc criterias have historically been called by numbers like CR0, CR1... however this makes it confusing to understand what each criteria is about. Change these criterias from numbers to symbolic names and add relevant comments. While we are at it, also reformat and add some comments to ext4_seq_mb_stats_show() for better readability. Additionally, define CR_FAST which signifies the criteria below which we can make quicker decisions like: * quitting early if (free block < requested len) * avoiding to scan free extents smaller than required len. * avoiding to initialize buddy cache and work with existing cache * limiting prefetches Suggested-by: Jan Kara <jack@suse.cz> Signed-off-by: Ojaswin Mujoo <ojaswin@linux.ibm.com> Link: https://lore.kernel.org/r/a2dc6ec5aea5e5e68cf8e788c2a964ffead9c8b0.1685449706.git.ojaswin@linux.ibm.com Signed-off-by: Theodore Ts'o <tytso@mit.edu> |

ext4: Add allocation criteria 1.5 (CR1_5)
CR1_5 aims to optimize allocations which can't be satisfied in CR1. The fact that we couldn't find a group in CR1 suggests that it would be difficult to find a continuous extent to compleltely satisfy our allocations. So before falling to the slower CR2, in CR1.5 we proactively trim the the preallocations so we can find a group with (free / fragments) big enough. This speeds up our allocation at the cost of slightly reduced preallocation. The patch also adds a new sysfs tunable: * /sys/fs/ext4/<partition>/mb_cr1_5_max_trim_order This controls how much CR1.5 can trim a request before falling to CR2. For example, for a request of order 7 and max trim order 2, CR1.5 can trim this upto order 5.

A large update for SMP management:
- Parallel CPU bringup
The reason why people are interested in parallel bringup is to shorten
the (kexec) reboot time of cloud servers to reduce the downtime of the
VM tenants.
The current fully serialized bringup does the following per AP:
1) Prepare callbacks (allocate, intialize, create threads)
2) Kick the AP alive (e.g. INIT/SIPI on x86)
3) Wait for the AP to report alive state
4) Let the AP continue through the atomic bringup
5) Let the AP run the threaded bringup to full online state
There are two significant delays:
#3 The time for an AP to report alive state in start_secondary() on
x86 has been measured in the range between 350us and 3.5ms
depending on vendor and CPU type, BIOS microcode size etc.
#4 The atomic bringup does the microcode update. This has been
measured to take up to ~8ms on the primary threads depending on
the microcode patch size to apply.
On a two socket SKL server with 56 cores (112 threads) the boot CPU
spends on current mainline about 800ms busy waiting for the APs to come
up and apply microcode. That's more than 80% of the actual onlining
procedure.
This can be reduced significantly by splitting the bringup mechanism
into two parts:
1) Run the prepare callbacks and kick the AP alive for each AP which
needs to be brought up.
The APs wake up, do their firmware initialization and run the low
level kernel startup code including microcode loading in parallel
up to the first synchronization point. (#1 and #2 above)
2) Run the rest of the bringup code strictly serialized per CPU
(#3 - #5 above) as it's done today.
Parallelizing that stage of the CPU bringup might be possible in
theory, but it's questionable whether required surgery would be
justified for a pretty small gain.
If the system is large enough the first AP is already waiting at the
first synchronization point when the boot CPU finished the wake-up of
the last AP. That reduces the AP bringup time on that SKL from ~800ms
to ~80ms, i.e. by a factor ~10x.
The actual gain varies wildly depending on the system, CPU, microcode
patch size and other factors. There are some opportunities to reduce
the overhead further, but that needs some deep surgery in the x86 CPU
bringup code.
For now this is only enabled on x86, but the core functionality
obviously works for all SMP capable architectures.
- Enhancements for SMP function call tracing so it is possible to locate
the scheduling and the actual execution points. That allows to measure
IPI delivery time precisely.

Pull btrfs updates from David Sterba:
"Mainly core changes, refactoring and optimizations.
Performance is improved in some areas, overall there may be a
cumulative improvement due to refactoring that removed lookups in the
IO path or simplified IO submission tracking.
Core:
- submit IO synchronously for fast checksums (crc32c and xxhash),
remove high priority worker kthread
- read extent buffer in one go, simplify IO tracking, bio submission
and locking
- remove additional tracking of redirtied extent buffers, originally
added for zoned mode but actually not needed
- track ordered extent pointer in bio to avoid rbtree lookups during
IO
- scrub, use recovered data stripes as cache to avoid unnecessary
read
- in zoned mode, optimize logical to physical mappings of extents
- remove PageError handling, not set by VFS nor writeback
- cleanups, refactoring, better structure packing
- lots of error handling improvements
- more assertions, lockdep annotations
- print assertion failure with the exact line where it happens
- tracepoint updates
- more debugging prints
Performance:
- speedup in fsync(), better tracking of inode logged status can
avoid transaction commit
- IO path structures track logical offsets in data structures and
does not need to look it up
User visible changes:
- don't commit transaction for every created subvolume, this can
reduce time when many subvolumes are created in a batch
- print affected files when relocation fails
- trigger orphan file cleanup during START_SYNC ioctl
Notable fixes:
- fix crash when disabling quota and relocation
- fix crashes when removing roots from drity list
- fix transacion abort during relocation when converting from newer
profiles not covered by fallback
- in zoned mode, stop reclaiming block groups if filesystem becomes
read-only
- fix rare race condition in tree mod log rewind that can miss some
btree node slots
- with enabled fsverity, drop up-to-date page bit in case the
verification fails"

trace,smp: Add tracepoints around remotelly called functions
The recently added ipi_send_{cpu,cpumask} tracepoints allow finding sources
of IPIs targeting CPUs running latency-sensitive applications.
For NOHZ_FULL CPUs, all IPIs are interference, and those tracepoints are
sufficient to find them and work on getting rid of them. In some setups
however, not *all* IPIs are to be suppressed, but long-running IPI
callbacks can still be problematic.
Add a pair of tracepoints to mark the start and end of processing a CSD IPI
callback, similar to what exists for softirq, workqueue or timer callbacks.

mm: compaction: remove compaction result helpers
Patch series "mm: compaction: cleanups & simplifications". These compaction cleanups are split out from the huge page allocator series[1], as requested by reviewer feedback. [1] https://lore.kernel.org/linux-mm/20230418191313.268131-1-hannes@cmpxchg.org/ This patch (of 5): The compaction result helpers encode quirks that are specific to the allocator's retry logic. E.g. COMPACT_SUCCESS and COMPACT_COMPLETE actually represent failures that should be retried upon, and so on. I frequently found myself pulling up the helper implementation in order to understand and work on the retry logic. They're not quite clean abstractions; rather they split the retry logic into two locations. Remove the helpers and inline the checks. Then comment on the result interpretations directly where the decision making happens.

NFSD 6.4 Release Notes
The big ticket item for this release is support for RPC-with-TLS [RFC 9289] has been added to the Linux NFS server. The goal is to provide a simple-to-deploy, low-overhead in-transit confidentiality and peer authentication mechanism.

SMP cross-CPU function-call updates for v6.4:
- Remove diagnostics and adjust config for CSD lock diagnostics
- Add a generic IPI-sending tracepoint, as currently there's no easy
way to instrument IPI origins: it's arch dependent and for some
major architectures it's not even consistently available.

SUNRPC: Support TLS handshake in the server-side TCP socket code
This patch adds opportunitistic RPC-with-TLS to the Linux in-kernel NFS server. If the client requests RPC-with-TLS and the user space handshake agent is running, the server will set up a TLS session. There are no policy settings yet. For example, the server cannot yet require the use of RPC-with-TLS to access its data. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> |

spi: Updates for v6.4
A fairly standard release for SPI with the exception of a change to the
API for specifying chip selects done in preparation for supporting
devices with more than one chip select, this required some mechanical
changes throughout the tree which have been cooking in -next happily for
a while. There's also a new API to allow us to TPM chips on half duplex
controllers.
There's three commits in here that were mangled by a bad interaction
between the alsa-devel mailing list software and b4, I didn't notice
until there were merges on top with it being SPI not ALSA. It seemed
clear enough to not be worth going back and fixing.
- Refactoring in preparation for supporting multiple chip selects for a
single device, needed by some flash devices, which required a change
in the SPI device API visible throughout the tree.
- Support for hardware assisted interaction with SPI TPMs on half
duplex controllers, implemented on nVidia Tedra210 QuadSPI.
- Optimisation for large transfers on fsl-cpm devices.
- Cleanups around device property use which fix some sisues with
fwnode.
- Use of both void remove() and devm_platform_.*ioremap_resource().
- Support for AMD Pensando Elba, Amlogic A1, Cadence device mode,
Intel MetorLake-S and StarFive J7110 QuadSPI.
The final commit converting to DEV_PM_OPS() was applied late to fix a
warning that was introduced by some of the earlier work.

Networking changes for 6.4.
Core
----
- Introduce a config option to tweak MAX_SKB_FRAGS. Increasing the
default value allows for better BIG TCP performances.
- Reduce compound page head access for zero-copy data transfers.
- RPS/RFS improvements, avoiding unneeded NET_RX_SOFTIRQ when possible.
- Threaded NAPI improvements, adding defer skb free support and unneeded
softirq avoidance.
- Address dst_entry reference count scalability issues, via false
sharing avoidance and optimize refcount tracking.
- Add lockless accesses annotation to sk_err[_soft].
- Optimize again the skb struct layout.
- Extends the skb drop reasons to make it usable by multiple
subsystems.
- Better const qualifier awareness for socket casts.
BPF
---
- Add skb and XDP typed dynptrs which allow BPF programs for more
ergonomic and less brittle iteration through data and variable-sized
accesses.
- Add a new BPF netfilter program type and minimal support to hook
BPF programs to netfilter hooks such as prerouting or forward.
- Add more precise memory usage reporting for all BPF map types.
- Adds support for using {FOU,GUE} encap with an ipip device operating
in collect_md mode and add a set of BPF kfuncs for controlling encap
params.
- Allow BPF programs to detect at load time whether a particular kfunc
exists or not, and also add support for this in light skeleton.
- Bigger batch of BPF verifier improvements to prepare for upcoming BPF
open-coded iterators allowing for less restrictive looping capabilities.
- Rework RCU enforcement in the verifier, add kptr_rcu and enforce BPF
programs to NULL-check before passing such pointers into kfunc.
- Add support for kptrs in percpu hashmaps, percpu LRU hashmaps and in
local storage maps.
- Enable RCU semantics for task BPF kptrs and allow referenced kptr
tasks to be stored in BPF maps.
- Add support for refcounted local kptrs to the verifier for allowing
shared ownership, useful for adding a node to both the BPF list and
rbtree.
- Add BPF verifier support for ST instructions in convert_ctx_access()
which will help new -mcpu=v4 clang flag to start emitting them.
- Add ARM32 USDT support to libbpf.
- Improve bpftool's visual program dump which produces the control
flow graph in a DOT format by adding C source inline annotations.
Protocols
---------
- IPv4: Allow adding to IPv4 address a 'protocol' tag. Such value
indicates the provenance of the IP address.
- IPv6: optimize route lookup, dropping unneeded R/W lock acquisition.
- Add the handshake upcall mechanism, allowing the user-space
to implement generic TLS handshake on kernel's behalf.
- Bridge: support per-{Port, VLAN} neighbor suppression, increasing
resilience to nodes failures.
- SCTP: add support for Fair Capacity and Weighted Fair Queueing
schedulers.
- MPTCP: delay first subflow allocation up to its first usage. This
will allow for later better LSM interaction.
- xfrm: Remove inner/outer modes from input/output path. These are
not needed anymore.
- WiFi:
- reduced neighbor report (RNR) handling for AP mode
- HW timestamping support
- support for randomized auth/deauth TA for PASN privacy
- per-link debugfs for multi-link
- TC offload support for mac80211 drivers
- mac80211 mesh fast-xmit and fast-rx support
- enable Wi-Fi 7 (EHT) mesh support
Netfilter
---------
- Add nf_tables 'brouting' support, to force a packet to be routed
instead of being bridged.
- Update bridge netfilter and ovs conntrack helpers to handle
IPv6 Jumbo packets properly, i.e. fetch the packet length
from hop-by-hop extension header. This is needed for BIT TCP
support.
- The iptables 32bit compat interface isn't compiled in by default
anymore.
- Move ip(6)tables builtin icmp matches to the udptcp one.
This has the advantage that icmp/icmpv6 match doesn't load the
iptables/ip6tables modules anymore when iptables-nft is used.
- Extended netlink error report for netdevice in flowtables and
netdev/chains. Allow for incrementally add/delete devices to netdev
basechain. Allow to create netdev chain without device.
Driver API
----------
- Remove redundant Device Control Error Reporting Enable, as PCI core
has already error reporting enabled at enumeration time.
- Move Multicast DB netlink handlers to core, allowing devices other
then bridge to use them.
- Allow the page_pool to directly recycle the pages from safely
localized NAPI.
- Implement lockless TX queue stop/wake combo macros, allowing for
further code de-duplication and sanitization.
- Add YNL support for user headers and struct attrs.
- Add partial YNL specification for devlink.
- Add partial YNL specification for ethtool.
- Add tc-mqprio and tc-taprio support for preemptible traffic classes.
- Add tx push buf len param to ethtool, specifies the maximum number
of bytes of a transmitted packet a driver can push directly to the
underlying device.
- Add basic LED support for switch/phy.

Merge tag 'net-next-6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Paolo Abeni:
"Core:
- Introduce a config option to tweak MAX_SKB_FRAGS. Increasing the
default value allows for better BIG TCP performances
- Reduce compound page head access for zero-copy data transfers
- RPS/RFS improvements, avoiding unneeded NET_RX_SOFTIRQ when
possible
- Threaded NAPI improvements, adding defer skb free support and
unneeded softirq avoidance
- Address dst_entry reference count scalability issues, via false
sharing avoidance and optimize refcount tracking
- Add lockless accesses annotation to sk_err[_soft]
- Optimize again the skb struct layout
- Extends the skb drop reasons to make it usable by multiple
subsystems
- Better const qualifier awareness for socket casts
BPF:
- Add skb and XDP typed dynptrs which allow BPF programs for more
ergonomic and less brittle iteration through data and
variable-sized accesses
- Add a new BPF netfilter program type and minimal support to hook
BPF programs to netfilter hooks such as prerouting or forward
- Add more precise memory usage reporting for all BPF map types
- Adds support for using {FOU,GUE} encap with an ipip device
operating in collect_md mode and add a set of BPF kfuncs for
controlling encap params
- Allow BPF programs to detect at load time whether a particular
kfunc exists or not, and also add support for this in light
skeleton
- Bigger batch of BPF verifier improvements to prepare for upcoming
BPF open-coded iterators allowing for less restrictive looping
capabilities
- Rework RCU enforcement in the verifier, add kptr_rcu and enforce
BPF programs to NULL-check before passing such pointers into kfunc
- Add support for kptrs in percpu hashmaps, percpu LRU hashmaps and
in local storage maps
- Enable RCU semantics for task BPF kptrs and allow referenced kptr
tasks to be stored in BPF maps
- Add support for refcounted local kptrs to the verifier for allowing
shared ownership, useful for adding a node to both the BPF list and
rbtree
- Add BPF verifier support for ST instructions in
convert_ctx_access() which will help new -mcpu=v4 clang flag to
start emitting them
- Add ARM32 USDT support to libbpf
- Improve bpftool's visual program dump which produces the control
flow graph in a DOT format by adding C source inline annotations
Protocols:
- IPv4: Allow adding to IPv4 address a 'protocol' tag. Such value
indicates the provenance of the IP address
- IPv6: optimize route lookup, dropping unneeded R/W lock acquisition
- Add the handshake upcall mechanism, allowing the user-space to
implement generic TLS handshake on kernel's behalf
- Bridge: support per-{Port, VLAN} neighbor suppression, increasing
resilience to nodes failures
- SCTP: add support for Fair Capacity and Weighted Fair Queueing
schedulers
- MPTCP: delay first subflow allocation up to its first usage. This
will allow for later better LSM interaction
- xfrm: Remove inner/outer modes from input/output path. These are
not needed anymore
- WiFi:
- reduced neighbor report (RNR) handling for AP mode
- HW timestamping support
- support for randomized auth/deauth TA for PASN privacy
- per-link debugfs for multi-link
- TC offload support for mac80211 drivers
- mac80211 mesh fast-xmit and fast-rx support
- enable Wi-Fi 7 (EHT) mesh support
Netfilter:
- Add nf_tables 'brouting' support, to force a packet to be routed
instead of being bridged
- Update bridge netfilter and ovs conntrack helpers to handle IPv6
Jumbo packets properly, i.e. fetch the packet length from
hop-by-hop extension header. This is needed for BIT TCP support
- The iptables 32bit compat interface isn't compiled in by default
anymore
- Move ip(6)tables builtin icmp matches to the udptcp one. This has
the advantage that icmp/icmpv6 match doesn't load the
iptables/ip6tables modules anymore when iptables-nft is used
- Extended netlink error report for netdevice in flowtables and
netdev/chains. Allow for incrementally add/delete devices to netdev
basechain. Allow to create netdev chain without device
Driver API:
- Remove redundant Device Control Error Reporting Enable, as PCI core
has already error reporting enabled at enumeration time
- Move Multicast DB netlink handlers to core, allowing devices other
then bridge to use them
- Allow the page_pool to directly recycle the pages from safely
localized NAPI
- Implement lockless TX queue stop/wake combo macros, allowing for
further code de-duplication and sanitization
- Add YNL support for user headers and struct attrs
- Add partial YNL specification for devlink
- Add partial YNL specification for ethtool
- Add tc-mqprio and tc-taprio support for preemptible traffic classes
- Add tx push buf len param to ethtool, specifies the maximum number
of bytes of a transmitted packet a driver can push directly to the
underlying device
- Add basic LED support for switch/phy
- Add NAPI documentation, stop relaying on external links
- Convert dsa_master_ioctl() to netdev notifier. This is a
preparatory work to make the hardware timestamping layer selectable
by user space
- Add transceiver support and improve the error messages for CAN-FD
controllers

dlm for 6.4
Remove some unused features (related to lock timeouts) that have been previously scheduled for removal. Fix a bug where the pending callback flag would be incorrectly cleared, which could potentially result in missing a completion callback. Use an unbound workqueue for dlm socket handling so that socket operations can be processed with less delay. Fix possible lockspace join connection errors with large clusters (e.g. over 16 nodes) caused by a small socket backlog setting. Use atomic bit ops for internal flags to help avoid mistakes copying flag values from messages. Fix recently introduced bug where memory for lvb data could be unnecessarily allocated for a lock. -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJkR/JxAAoJEDgbc8f8gGmq2p0P/j3OcxdOXkx9LVpKdjuAhK/M A4Q46J9Z/Ytl4vT7x6i4x2fZXk8cTOkQZ3TkYMGbIc8LV4FZpO4/pIP+GnSDkmwY 1/AJgauskoewPuCNe+SUCawFMKPhUCXKOXNhyfAHlBS+NS8iIJhVKOP7mOMUawKs 4WiI6fEFBig2z56LHgnAIdzx1UGJ+AE1XlwEca1jVvtMYW03HX9h5Tt1BP1NeAKx oPrYQaUsctHlAI+fo0PnjimGcjXa2av9YNnTHpqVfYw6ntSdriEXQVosX/tcRV8E dVXmQP2Ox20mNRu9vHkAK8x2LQLj7HuwmohdUvvDFp1cIEglbiRdF6IolyhD2Up1 ETeJ5EU/6ktJOHrOewUCTcJoLrAcwmklgj9fzvW7fPN4zNsEUCYgoenuSK8bW+la jDbO26Rh+cMg2pC6Rz8z8azadwTQlFXDjvTDOnmb2jr+tfIEWj/VTWCTQ4Un3EEg 4xJ1dCvlLCRkYoDN3QTF9TxapSTohtjtQl85yrLULhdUWhQuRQd93rHeNgwDf8Ys NUzuL+IR+SEfvVyRezYfdyUBT26ld8pGVzJqlKvXUXTPBypnw9aoGAYhXx3A8fYo QLIz7lc0/pvkWaQ9zNyedf8LDIYCbZuTcMpmTEgLy+q6BTJWS2ZJT5oeNvGvnRw5 Zc7iUmGNQ5XKuVEhtTFA =900J -----END PGP SIGNATURE----- Merge tag 'dlm-6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/teigland/linux-dlm Pull dlm updates from David Teigland: - Remove some unused features (related to lock timeouts) that have been previously scheduled for removal - Fix a bug where the pending callback flag would be incorrectly cleared, which could potentially result in missing a completion callback - Use an unbound workqueue for dlm socket handling so that socket operations can be processed with less delay - Fix possible lockspace join connection errors with large clusters (e.g. over 16 nodes) caused by a small socket backlog setting - Use atomic bit ops for internal flags to help avoid mistakes copying flag values from messages - Fix recently introduced bug where memory for lvb data could be unnecessarily allocated for a lock * tag 'dlm-6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/teigland/linux-dlm: fs: dlm: stop unnecessarily filling zero ms_extra bytes fs: dlm: switch lkb_sbflags to atomic ops fs: dlm: rsb hash table flag value to atomic ops fs: dlm: move internal flags to atomic ops fs: dlm: change dflags to use atomic bits fs: dlm: store lkb distributed flags into own value fs: dlm: remove DLM_IFL_LOCAL_MS flag fs: dlm: rename stub to local message flag fs: dlm: remove deprecated code parts DLM: increase socket backlog to avoid hangs with 16 nodes fs: dlm: add unbound flag to dlm_io workqueue fs: dlm: fix DLM_IFL_CB_PENDING gets overwritten |

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
- add btrfs_assertfail() to objtool table"

There are a number of major cleanups in ext4 this cycle:
* The data=journal writepath has been significantly cleaned up and
simplified, and reduces a large number of data=journal special cases
by Jan Kara.
* Ojaswin Muhoo has replaced linked list used to track extents that
have been used for inode preallocation with a red-black tree in the
multi-block allocator. This improves performance for workloads
which do a large number of random allocating writes.
* Thanks to Kemeng Shi for a lot of cleanup and bug fixes in the
multi-block allocator.
* Matthew wilcox has converted the code paths for reading and writing
ext4 pages to use folios.
* Jason Yan has continued to factor out ext4_fill_super() into smaller
functions for improve ease of maintenance and comprehension.
* Josh Triplett has created an uapi header for ext4 userspace API's.

NFSD: Watch for rq_pages bounds checking errors in nfsd_splice_actor()
There have been several bugs over the years where the NFSD splice actor has attempted to write outside the rq_pages array. This is a "should never happen" condition, but if for some reason the pipe splice actor should attempt to walk past the end of rq_pages, it needs to terminate the READ operation to prevent corruption of the pointer addresses in the fields just beyond the array. A server crash is thus prevented. Since the code is not behaving, the READ operation returns -EIO to the client. None of the READ payload data can be trusted if the splice actor isn't operating as expected.

Pull erofs updates from Gao Xiang:
"In this cycle, sub-page block support for uncompressed files is
available. It's mainly used to enable original signing ('golden')
4k-block images on arm64 with 16/64k pages. In addition, end users
could also use this feature to build a manifest to directly refer to
golden tar data.
Besides, long xattr name prefix support is also introduced in this
cycle to avoid too many xattrs with the same prefix (e.g. overlayfs
xattrs). It's useful for erofs + overlayfs combination (like Composefs
model): the image size is reduced by ~14% and runtime performance is
also slightly improved.
Others are random fixes and cleanups as usual.

net/handshake: Create a NETLINK service for handling handshake requests
When a kernel consumer needs a transport layer security session, it first needs a handshake to negotiate and establish a session. This negotiation can be done in user space via one of the several existing library implementations, or it can be done in the kernel. No in-kernel handshake implementations yet exist. In their absence, we add a netlink service that can: a. Notify a user space daemon that a handshake is needed. b. Once notified, the daemon calls the kernel back via this netlink service to get the handshake parameters, including an open socket on which to establish the session. c. Once the handshake is complete, the daemon reports the session status and other information via a second netlink operation. This operation marks that it is safe for the kernel to use the open socket and the security session established there. The notification service uses a multicast group. Each handshake mechanism (eg, tlshd) adopts its own group number so that the handshake services are completely independent of one another. The kernel can then tell via netlink_has_listeners() whether a handshake service is active and prepared to handle a handshake request. A new netlink operation, ACCEPT, acts like accept(2) in that it instantiates a file descriptor in the user space daemon's fd table. If this operation is successful, the reply carries the fd number, which can be treated as an open and ready file descriptor. While user space is performing the handshake, the kernel keeps its muddy paws off the open socket. A second new netlink operation, DONE, indicates that the user space daemon is finished with the socket and it is safe for the kernel to use again. The operation also indicates whether a session was established successfully. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

mm/khugepaged: skip shmem with userfaultfd
Make sure that collapse_file respects any userfaultfds registered with MODE_MISSING. If userspace has any such userfaultfds registered, then for any page which it knows to be missing, it may expect a UFFD_EVENT_PAGEFAULT. This means collapse_file needs to be careful when collapsing a shmem range would result in replacing an empty page with a THP, to avoid breaking userfaultfd. Synchronization when checking for userfaultfds in collapse_file is tricky because the mmap locks can't be used to prevent races with the registration of new userfaultfds. Instead, we provide synchronization by ensuring that userspace cannot observe the fact that pages are missing before we check for userfaultfds. Although this allows registration of a userfaultfd to race with collapse_file, it ensures that userspace cannot observe any pages transition from missing to present after such a race occurs. This makes such a race indistinguishable to the collapse occurring immediately before the userfaultfd registration. The first step to provide this synchronization is to stop filling gaps during the loop iterating over the target range, since the page cache lock can be dropped during that loop. The second step is to fill the gaps with XA_RETRY_ENTRY after the page cache lock is acquired the final time, to avoid races with accesses to the page cache that only take the RCU read lock. The fact that we don't fill holes during the initial iteration means that collapse_file now has to handle faults occurring during the collapse. This is done by re-validating the number of missing pages after acquiring the page cache lock for the final time. This fix is targeted at khugepaged, but the change also applies to MADV_COLLAPSE. MADV_COLLAPSE on a range with a userfaultfd will now return EBUSY if there are any missing pages (instead of succeeding on shmem and returning EINVAL on anonymous memory). There is also now a window during MADV_COLLAPSE where a fault on a missing page will cause the syscall to fail with EAGAIN. The fact that intermediate page cache state can no longer be observed before the rollback of a failed collapse is also technically a userspace-visible change (via at least SEEK_DATA and SEEK_END), but it is exceedingly unlikely that anything relies on being able to observe that transient state.

mm/khugepaged: recover from poisoned anonymous memory
Problem ======= Memory DIMMs are subject to multi-bit flips, i.e. memory errors. As memory size and density increase, the chances of and number of memory errors increase. The increasing size and density of server RAM in the data center and cloud have shown increased uncorrectable memory errors. There are already mechanisms in the kernel to recover from uncorrectable memory errors. This series of patches provides the recovery mechanism for the particular kernel agent khugepaged when it collapses memory pages. Impact ====== The main reason we chose to make khugepaged collapsing tolerant of memory failures was its high possibility of accessing poisoned memory while performing functionally optional compaction actions. Standard applications typically don't have strict requirements on the size of its pages. So they are given 4K pages by the kernel. The kernel is able to improve application performance by either 1) giving applications 2M pages to begin with, or 2) collapsing 4K pages into 2M pages when possible. This collapsing operation is done by khugepaged, a kernel agent that is constantly scanning memory. When collapsing 4K pages into a 2M page, it must copy the data from the 4K pages into a physically contiguous 2M page. Therefore, as long as there exists one poisoned cache line in collapsible 4K pages, khugepaged will eventually access it. The current impact to users is a machine check exception triggered kernel panic. However, khugepaged’s compaction operations are not functionally required kernel actions. Therefore making khugepaged tolerant to poisoned memory will greatly improve user experience. This patch series is for cases where khugepaged is the first guy that detects the memory errors on the poisoned pages. IOW, the pages are not known to have memory errors when khugepaged collapsing gets to them. In our observation, this happens frequently when the huge page ratio of the system is relatively low, which is fairly common in virtual machines running on cloud. Solution ======== As stated before, it is less desirable to crash the system only because khugepaged accesses poisoned pages while it is collapsing 4K pages. The high level idea of this patch series is to skip the group of pages (usually 512 4K-size pages) once khugepaged finds one of them is poisoned, as these pages have become ineligible to be collapsed. We are also careful to unwind operations khuagepaged has performed before it detects memory failures. For example, before copying and collapsing a group of anonymous pages into a huge page, the source pages will be isolated and their page table is unlinked from their PMD. These operations need to be undone in order to ensure these pages are not changed/lost from the perspective of other threads (both user and kernel space). As for file backed memory pages, there already exists a rollback case. This patch just extends it so that khugepaged also correctly rolls back when it fails to copy poisoned 4K pages. This patch (of 3): Make __collapse_huge_page_copy return whether copying anonymous pages succeeded, and make collapse_huge_page handle the return status. Break existing PTE scan loop into two for-loops. The first loop copies source pages into target huge page, and can fail gracefully when running into memory errors in source pages. If copying all pages succeeds, the second loop releases and clears up these normal pages. Otherwise, the second loop rolls back the page table and page states by: - re-establishing the original PTEs-to-PMD connection. - releasing source pages back to their LRU list. Tested manually: 0. Enable khugepaged on system under test. 1. Start a two-thread application. Each thread allocates a chunk of non-huge anonymous memory buffer. 2. Pick 4 random buffer locations (2 in each thread) and inject uncorrectable memory errors at corresponding physical addresses. 3. Signal both threads to make their memory buffer collapsible, i.e. calling madvise(MADV_HUGEPAGE). 4. Wait and check kernel log: khugepaged is able to recover from poisoned pages and skips collapsing them. 5. Signal both threads to inspect their buffer contents and make sure no data corruption.

btrfs: replace btrfs_io_context::raid_map with a fixed u64 value
In btrfs_io_context structure, we have a pointer raid_map, which indicates the logical bytenr for each stripe. But considering we always call sort_parity_stripes(), the result raid_map[] is always sorted, thus raid_map[0] is always the logical bytenr of the full stripe. So why we waste the space and time (for sorting) for raid_map? This patch will replace btrfs_io_context::raid_map with a single u64 number, full_stripe_start, by: - Replace btrfs_io_context::raid_map with full_stripe_start - Replace call sites using raid_map[0] to use full_stripe_start - Replace call sites using raid_map[i] to compare with nr_data_stripes. The benefits are: - Less memory wasted on raid_map It's sizeof(u64) * num_stripes vs sizeof(u64). It'll always save at least one u64, and the benefit grows larger with num_stripes. - No more weird alloc_btrfs_io_context() behavior As there is only one fixed size + one variable length array.

erofs: avoid hardcoded blocksize for subpage block support
As the first step of converting hardcoded blocksize to that specified in on-disk superblock, convert all call sites of hardcoded blocksize to sb->s_blocksize except for: 1) use sbi->blkszbits instead of sb->s_blocksize in erofs_superblock_csum_verify() since sb->s_blocksize has not been updated with the on-disk blocksize yet when the function is called. 2) use inode->i_blkbits instead of sb->s_blocksize in erofs_bread(), since the inode operated on may be an anonymous inode in fscache mode. Currently the anonymous inode is allocated from an anonymous mount maintained in erofs, while in the near future we may allocate anonymous inodes from a generic API directly and thus have no access to the anonymous inode's i_sb. Thus we keep the block size in i_blkbits for anonymous inodes in fscache mode. Be noted that this patch only gets rid of the hardcoded blocksize, in preparation for actually setting the on-disk block size in the following patch. The hard limit of constraining the block size to PAGE_SIZE still exists until the next patch.

softirq: Add trace points for tasklet entry/exit
Tasklets are supposed to finish their work quickly and should not block the
current running process, but it is not guaranteed that they do so.
Currently softirq_entry/exit can be used to analyse the total tasklets
execution time, but that's not helpful to track individual tasklets
execution time. That makes it hard to identify tasklet functions, which
take more time than expected.
Add tasklet_entry/exit trace point support to track individual tasklet
execution.
Trivial usage example:
# echo 1 > /sys/kernel/debug/tracing/events/irq/tasklet_entry/enable

rcu/trace: use strscpy() to instead of strncpy()
This commit saves a line of code by switching from strncpy() to strscpy() by permitting the later NUL assignment to be removed. While in the area, save another line by taking advantage of 100 characters.

net: qrtr: correct types of trace event parameters
The arguments passed to the trace events are of type unsigned int,
however the signature of the events used __le32 parameters.
I may be missing the point here, but sparse flagged this and it
does seem incorrect to me.

tracing: Error if a trace event has an array for a __field()
A __field() in the TRACE_EVENT() macro is used to set up the fields of the
trace event data. It is for single storage units (word, char, int,
pointer, etc) and not for complex structures or arrays. Unfortunately,
there's nothing preventing the build from accepting:
__field(int, arr[5]);
from building. It will turn into a array value. This use to work fine, as
the offset and size use to be determined by the macro using the field name,
but things have changed and the offset and size are now determined by the
type. So the above would only be size 4, and the next field will be
located 4 bytes from it (instead of 20).
The proper way to declare static arrays is to use the __array() macro.
Instead of __field(int, arr[5]) it should be __array(int, arr, 5).
Add some macro tricks to the building of a trace event from the
TRACE_EVENT() macro such that __field(int, arr[5]) will fail to build. A
comment by the failure will explain why the build failed.

thermal/core: Relocate the traces definition in thermal directory
The traces are exported but only local to the thermal core code. On the other side, the traces take the thermal zone device structure as argument, thus they have to rely on the exported thermal.h header file. As we want to move the structure to the private thermal core header, first we have to relocate those traces to the same place as many drivers do.

kasan: remove PG_skip_kasan_poison flag
Code inspection reveals that PG_skip_kasan_poison is redundant with kasantag, because the former is intended to be set iff the latter is the match-all tag. It can also be observed that it's basically pointless to poison pages which have kasantag=0, because any pages with this tag would have been pointed to by pointers with match-all tags, so poisoning the pages would have little to no effect in terms of bug detection. Therefore, change the condition in should_skip_kasan_poison() to check kasantag instead, and remove PG_skip_kasan_poison and associated flags.

mm, printk: introduce new format %pGt for page_type
%pGp format is used to display 'flags' field of a struct page. However, some page flags (i.e. PG_buddy, see page-flags.h for more details) are stored in page_type field. To display human-readable output of page_type, introduce %pGt format. It is important to note the meaning of bits are different in page_type. if page_type is 0xffffffff, no flags are set. Setting PG_buddy (0x00000080) flag results in a page_type of 0xffffff7f. Clearing a bit actually means setting a flag. Bits in page_type are inverted when displaying type names. Only values for which page_type_has_type() returns true are considered as page_type, to avoid confusion with mapcount values. if it returns false, only raw values are displayed and not page type names.

Add support for writeback of journalled data directly into ext4_writepages() instead of offloading it to write_cache_pages(). This actually significantly simplifies the code and reduces code duplication. For checkpointing of committed data we can use ext4_writepages() rightaway the same way as writeback of ordered data uses it on transaction commit. For journalling of dirty mapped pages, we need to add a special case to mpage_prepare_extent_to_map() to add all page buffers to the journal.

spi: Replace all spi->chip_select and spi->cs_gpiod references with function call
Supporting multi-cs in spi drivers would require the chip_select & cs_gpiod members of struct spi_device to be an array. But changing the type of these members to array would break the spi driver functionality. To make the transition smoother introduced four new APIs to get/set the spi->chip_select & spi->cs_gpiod and replaced all spi->chip_select and spi->cs_gpiod references with get or set API calls. While adding multi-cs support in further patches the chip_select & cs_gpiod members of the spi_device structure would be converted to arrays & the "idx" parameter of the APIs would be used as array index i.e., spi->chip_select[idx] & spi->cs_gpiod[idx] respectively.

fs: dlm: change dflags to use atomic bits
Currently manipulating lkb_dflags assumes to held the rsb lock assigned to the lkb. This is held by dlm message processing after certain time to lookup the right rsb from the received lkb message id. For user space locks flags, which is currently the only use case for lkb_dflags, flags are also being set during dlm character device handling without holding the rsb lock. To minimize the risk that bit operations are getting corrupted we switch to atomic bit operations. This patch will also introduce helpers to snapshot atomic bit values in an non atomic way. There might be still issues with the flag handling e.g. running in case of manipulating bit ops and snapshot them at the same time, but this patch minimize them and will start to use atomic bit operations.

fs: dlm: store lkb distributed flags into own value
This patch stores lkb distributed flags value in an separate value instead of sharing internal and distributed flags in lkb->lkb_flags value. This has the advantage to not mask/write back flag values in receive_flags() functionality. The dlm debug_fs does not provide the distributed flags anymore, those can be added in future.

fs: dlm: remove DLM_IFL_LOCAL_MS flag
The DLM_IFL_LOCAL_MS flag is an internal non shared flag but used in m_flags of dlm messages. It is not shared because it is only used for local messaging. Instead using DLM_IFL_LOCAL_MS in dlm messages we pass a parameter around to signal local messaging or not. This patch is adding the local parameter to signal local messaging.

fs: dlm: rename stub to local message flag
This patch renames DLM_IFL_STUB_MS to DLM_IFL_LOCAL_MS flag. The DLM_IFL_STUB_MS flag is somewhat misnamed, it means the dlm message is used for local message transfer only. It is used by recovery to resolve lock states if a node got fenced. Signed-off-by: Alexander Aring <aahringo@redhat.com> Signed-off-by: David Teigland <teigland@redhat.com> |

ARM: SoC drivers for 6.3
As usual, there are lots of minor driver changes across SoC platforms
from NXP, Amlogic, AMD Zynq, Mediatek, Qualcomm, Apple and Samsung.
These usually add support for additional chip variations in existing
drivers, but also add features or bugfixes.
The SCMI firmware subsystem gains a unified raw userspace interface
through debugfs, which can be used for validation purposes.
Newly added drivers include:
- New power management drivers for StarFive JH7110, Allwinner D1 and
Renesas RZ/V2M
- A driver for Qualcomm battery and power supply status
- A SoC device driver for identifying Nuvoton WPCM450 chips
- A regulator coupler driver for Mediatek MT81xxv

Decoder Capability to translate the CXL DVSEC Range Registers into
'struct cxl_decoder' objects.
- Set timestamp: Per spec, set the device timestamp in case of hotplug,

Pull Compute Express Link (CXL) updates from Dan Williams:
"To date Linux has been dependent on platform-firmware to map CXL RAM
regions and handle events / errors from devices. With this update we
can now parse / update the CXL memory layout, and report events /
errors from devices. This is a precursor for the CXL subsystem to
handle the end-to-end "RAS" flow for CXL memory. i.e. the flow that
for DDR-attached-DRAM is handled by the EDAC driver where it maps
system physical address events to a field-replaceable-unit (FRU /
endpoint device). In general, CXL has the potential to standardize
what has historically been a pile of memory-controller-specific error
handling logic.
Another change of note is the default policy for handling RAM-backed
device-dax instances. Previously the default access mode was "device",
mmap(2) a device special file to access memory. The new default is
"kmem" where the address range is assigned to the core-mm via
add_memory_driver_managed(). This saves typical users from wondering
why their platform memory is not visible via free(1) and stuck behind
a device-file. At the same time it allows expert users to deploy
policy to, for example, get dedicated access to high performance
memory, or hide low performance memory from general purpose kernel
allocations. This affects not only CXL, but also systems with
high-bandwidth-memory that platform-firmware tags with the
EFI_MEMORY_SP (special purpose) designation.
Summary:
- CXL RAM region enumeration: instantiate 'struct cxl_region' objects
for platform firmware created memory regions
- CXL RAM region provisioning: complement the existing PMEM region
creation support with RAM region support
- "Soft Reservation" policy change: Online (memory hot-add)
soft-reserved memory (EFI_MEMORY_SP) by default, but still allow

IOMMU Updates for Linux v6.3:
Including:
- Consolidate iommu_map/unmap functions. There have been
blocking and atomic variants so far, but that was problematic
as this approach does not scale with required new variants
which just differ in the GFP flags used.
So Jason consolidated this back into single functions that
take a GFP parameter. This has the potential to cause
conflicts with other trees, as they introduce new call-sites
for the changed functions. I offered them to pull in the
branch containing these changes and resolve it, but I am not
sure everyone did that. The conflicts this caused with
upstream up to v6.2-rc8 are resolved in the final merge
commit.
- Retire the detach_dev() call-back in iommu_ops
- Arm SMMU updates from Will:
- Device-tree binding updates:
* Cater for three power domains on SM6375
* Document existing compatible strings for Qualcomm SoCs
* Tighten up clocks description for platform-specific compatible strings
- Enable Qualcomm workarounds for some additional platforms that need them
- Intel VT-d updates from Lu Baolu:
- Add Intel IOMMU performance monitoring support
- Set No Execute Enable bit in PASID table entry
- Two performance optimizations
- Fix PASID directory pointer coherency
- Fix missed rollbacks in error path
- Cleanups
- Apple t8110 DART support
- Exynos IOMMU:

NFSD 6.3 Release Notes
Two significant security enhancements are part of this release:
* NFSD's RPC header encoding and decoding, including RPCSEC GSS
and gssproxy header parsing, has been overhauled to make it
more memory-safe.
* Support for Kerberos AES-SHA2-based encryption types has been
added for both the NFS client and server. This provides a clean
path for deprecating and removing insecure encryption types
based on DES and SHA-1. AES-SHA2 is also FIPS-140 compliant, so
that NFS with Kerberos may now be used on systems with fips
enabled.
In addition to these, NFSD is now able to handle crossing into an
auto-mounted mount point on an exported NFS mount. A number of
fixes have been made to NFSD's server-side copy implementation.
RPC metrics have been converted to per-CPU variables. This helps
reduce unnecessary cross-CPU and cross-node memory bus traffic,
and significantly reduces noise when KCSAN is enabled.

Merge tag 'nfsd-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux
Pull nfsd updates from Chuck Lever:
"Two significant security enhancements are part of this release:
- NFSD's RPC header encoding and decoding, including RPCSEC GSS and
gssproxy header parsing, has been overhauled to make it more
memory-safe.
- Support for Kerberos AES-SHA2-based encryption types has been added
for both the NFS client and server. This provides a clean path for
deprecating and removing insecure encryption types based on DES and
SHA-1. AES-SHA2 is also FIPS-140 compliant, so that NFS with
Kerberos may now be used on systems with fips enabled.
In addition to these, NFSD is now able to handle crossing into an
auto-mounted mount point on an exported NFS mount. A number of fixes

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.

Scheduler updates in this cycle are:
- Improve the scalability of the CFS bandwidth unthrottling logic
with large number of CPUs.
- Fix & rework various cpuidle routines, simplify interaction with
the generic scheduler code. Add __cpuidle methods as noinstr to
objtool's noinstr detection and fix boatloads of cpuidle bugs & quirks.
- Add new ABI: introduce MEMBARRIER_CMD_GET_REGISTRATIONS,
to query previously issued registrations.
- Limit scheduler slice duration to the sysctl_sched_latency period,
to improve scheduling granularity with a large number of SCHED_IDLE
tasks.
- Debuggability enhancement on sys_exit(): warn about disabled IRQs,
but also enable them to prevent a cascade of followup problems and
repeat warnings.
- Fix the rescheduling logic in prio_changed_dl().
- Micro-optimize cpufreq and sched-util methods.
- Micro-optimize ttwu_runnable()
- Micro-optimize the idle-scanning in update_numa_stats(),
select_idle_capacity() and steal_cookie_task().
- Update the RSEQ code & self-tests
- Constify various scheduler methods
- Remove unused methods
- Refine __init tags
- Documentation updates
- ... Misc other cleanups, fixes

Pull btrfs updates from David Sterba:
"The usual mix of performance improvements and new features.
The core change is reworking how checksums are processed, with
followup cleanups and simplifications. There are two minor changes in
block layer and iomap code.
Features:
- block group allocation class heuristics:
- pack files by size (up to 128k, up to 8M, more) to avoid
fragmentation in block groups, assuming that file size and life
time is correlated, in particular this may help during balance
- with tracepoints and extensible in the future
Performance:
- send: cache directory utimes and only emit the command when
necessary
- speedup up to 10x
- smaller final stream produced (no redundant utimes commands
issued)
- compatibility not affected
- fiemap: skip backref checks for shared leaves
- speedup 3x on sample filesystem with all leaves shared (e.g. on
snapshots)
- micro optimized b-tree key lookup, speedup in metadata operations
(sample benchmark: fs_mark +10% of files/sec)
Core changes:
- change where checksumming is done in the io path:
- checksum and read repair does verification at lower layer
- cascaded cleanups and simplifications
- raid56 refactoring and cleanups
Fixes:
- sysfs: make sure that a run-time change of a feature is correctly
tracked by the feature files
- scrub: better reporting of tree block errors
Other:
- locally enable -Wmaybe-uninitialized after fixing all warnings
- misc cleanups, spelling fixes
Other code:
- block: export bio_split_rw
- iomap: remove IOMAP_F_ZONE_APPEND"

Pull erofs updates from Gao Xiang:
"The most noticeable feature for this cycle is per-CPU kthread
decompression since Android use cases need low-latency I/O handling in
order to ensure the app runtime performance, currently unbounded
workqueue latencies are not quite good for production on many aarch64
hardwares and thus we need to introduce a deterministic expectation
for these. Decompression is CPU-intensive and it is sleepable for
EROFS, so other alternatives like decompression under softirq contexts
are not considered. More details are in the corresponding commit
message.
Others are random cleanups around the whole codebase and we will
continue to clean up further in the next few months.
Due to Lunar New Year holidays, some other new features were not
completely reviewed and solidified as expected and we may delay them
into the next version.
Summary:
- Add per-cpu kthreads for low-latency decompression for Android use
cases
- Get rid of tagged pointer helpers since they are rarely used now
- Several code cleanups to reduce codebase

rxrpc: Fix overproduction of wakeups to recvmsg()
Fix three cases of overproduction of wakeups:
(1) rxrpc_input_split_jumbo() conditionally notifies the app that there's
data for recvmsg() to collect if it queues some data - and then its
only caller, rxrpc_input_data(), goes and wakes up recvmsg() anyway.
Fix the rxrpc_input_data() to only do the wakeup in failure cases.
(2) If a DATA packet is received for a call by the I/O thread whilst
recvmsg() is busy draining the call's rx queue in the app thread, the
call will left on the recvmsg() queue for recvmsg() to pick up, even
though there isn't any data on it.
This can cause an unexpected recvmsg() with a 0 return and no MSG_EOR
set after the reply has been posted to a service call.
Fix this by discarding pending calls from the recvmsg() queue that
don't need servicing yet.
(3) Not-yet-completed calls get requeued after having data read from them,
even if they have no data to read.
Fix this by only requeuing them if they have data waiting on them; if
they don't, the I/O thread will requeue them when data arrives or they
fail.

erofs: remove unused EROFS_GET_BLOCKS_RAW flag
For erofs_map_blocks() and erofs_map_blocks_flatmode(), the flags argument is always EROFS_GET_BLOCKS_RAW. Thus remove the unused flags parameter for these two functions. Besides EROFS_GET_BLOCKS_RAW is originally introduced for reading compressed (raw) data for compressed files. However it's never used actually and let's remove it now.
