x86/xen: move paravirt lazy code
Only Xen is using the paravirt lazy mode code, so it can be moved to Xen specific sources. This allows to make some of the functions static or to merge them into their only call sites. While at it do a rename from "paravirt" to "xen" for all moved specifiers. No functional change.

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> |

Networking changes for 6.6.
Core
----
- Increase size limits for to-be-sent skb frag allocations. This
allows tun, tap devices and packet sockets to better cope with large
writes operations.
- Store netdevs in an xarray, to simplify iterating over netdevs.
- 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.
- Add yaml netlink spec for netlink-raw families, allow route, link and
address related queries via the ynl tool.

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"

"In this cycle, a xattr bloom filter feature is introduced to speed up
negative xattr lookups, which was originally suggested by Alexander

Additionally, the DEFLATE algorithm is now supported, which can be

supported compression algorithm can be selected on a per-file basis
for specific access patterns too.

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(). No return values were used, so direct replacement is safe.

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.
