bcachefs: Don't log errors if BCH_WRITE_ALLOC_NOWAIT
Previously, we added logging in the write path to ensure that any unexpected errors getting reported to userspace have a log message; but BCH_WRITE_ALLOC_NOWAIT is a special case, it's used for promotes where errors are expected and not reported out to userspace - so we need to silence those.

execve: open the executable file before doing anything else
No point in allocating a new mm, counting arguments and environment variables etc if we're just going to return ENOENT. This patch does expose the fact that 'do_filp_open()' that execve() uses is still unnecessarily expensive in the failure case, because it allocates the 'struct file *' early, even if the path lookup (which is heavily optimized) fails. So that remains an unnecessary cost in the "no such executable" case, but it's a separate issue. Regardless, I do not want to do _both_ a filename_lookup() and a later do_filp_open() like the origin patch by Josh Triplett did in [1].

Merge tag 'vfs-6.8.netfs' of gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs
Pull netfs updates from Christian Brauner:
"This extends the netfs helper library that network filesystems can use
to replace their own implementations. Both afs and 9p are ported. cifs
is ready as well but the patches are way bigger and will be routed
separately once this is merged. That will remove lots of code as well.
The overal goal is to get high-level I/O and knowledge of the page
cache and ouf of the filesystem drivers. This includes knowledge about
the existence of pages and folios
The pull request converts afs and 9p. This removes about 800 lines of
code from afs and 300 from 9p. For 9p it is now possible to do writes
in larger than a page chunks. Additionally, multipage folio support
can be turned on for 9p. Separate patches exist for cifs removing
another 2000+ lines. I've included detailed information in the
individual pulls I took.
Summary:
- Add NFS-style (and Ceph-style) locking around DIO vs buffered I/O
calls to prevent these from happening at the same time.
- Support for direct and unbuffered I/O.
- Support for write-through caching in the page cache.
- O_*SYNC and RWF_*SYNC writes use write-through rather than writing
to the page cache and then flushing afterwards.
- Support for write-streaming.
- Support for write grouping.
- Skip reads for which the server could only return zeros or EOF.
- The fscache module is now part of the netfs library and the
corresponding maintainer entry is updated.
- Some helpers from the fscache subsystem are renamed to mark them as
belonging to the netfs library.
- Follow-up fixes for the netfs library.
- Follow-up fixes for the 9p conversion"

cifs: update iface_last_update on each query-and-update
iface_last_update was an unused field when it was introduced.
Later, when we had periodic update of server interface list,
this field was used regularly to decide when to update next.
However, with the new logic of updating the interfaces, it
becomes crucial that this field be updated whenever
parse_server_interfaces runs successfully.
This change updates this field when either the server does
not support query of interfaces; so that we do not query
the interfaces repeatedly. It also updates the field when
the function reaches the end.

cifs: handle servers that still advertise multichannel after disabling
Some servers like Azure SMB servers always advertise multichannel capability in server capabilities list. Such servers return error STATUS_NOT_IMPLEMENTED for ioctl calls to query server interfaces, and expect clients to consider that as a sign that they do not support multichannel. We already handled this at mount time. Soon after the tree connect, we query server interfaces. And when server returned STATUS_NOT_IMPLEMENTED, we kept interface list as empty. When cifs_try_adding_channels gets called, it would not find any interfaces, so will not add channels. For the case where an active multichannel mount exists, and multichannel is disabled by such a server, this change will now allow the client to disable secondary channels on the mount. It will check the return status of query server interfaces call soon after a tree reconnect. If the return status is EOPNOTSUPP, then instead of the check to add more channels, we'll disable the secondary channels instead. For better code reuse, this change also moves the common code for disabling multichannel to a helper function.

These functions were called by lookup and the readdir logic, where readdir needed it to up the ref count of the dentry but the lookup did not. A "lookup" parameter was passed in to tell it what to do, but this complicated the code. It is better to just always up the ref count and require the caller to decrement it, even for lookup. - Modify the .iterate_shared callback to not use the dcache_readdir() logic and just handle what gets displayed by that one function. This removes the need for eventfs to hijack the file->private_data from the dcache_readdir() "cursor" pointer, and makes the code a bit more sane - Use the root and instance inodes for default ownership. Instead of walking the dentry tree and updating each dentry gid, use the getattr(), setattr() and permission() callbacks to set the ownership and permissions using the root or instance as the default - Some other optimizations with the eventfs iterate_shared logic - Hard-code the inodes for eventfs to the same number for files, and the same number for directories - Have getdent() not create dentries/inodes in iterate_shared() as now it has hard-coded inode numbers - Use kcalloc() instead of kzalloc() on a list of elements - Fix seq_buf warning and make static work properly. * tag 'eventfs-v6.8-2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: seq_buf: Make DECLARE_SEQ_BUF() usable eventfs: Use kcalloc() instead of kzalloc() eventfs: Do not create dentries nor inodes in iterate_shared eventfs: Have the inodes all for files and directories all be the same eventfs: Shortcut eventfs_iterate() by skipping entries already read eventfs: Read ei->entries before ei->children in eventfs_iterate() eventfs: Do ctx->pos update for all iterations in eventfs_iterate() eventfs: Have eventfs_iterate() stop immediately if ei->is_freed is set tracefs/eventfs: Use root and instance inodes as default ownership eventfs: Stop using dcache_readdir() for getdents() eventfs: Remove "lookup" parameter from create_dir/file_dentry() |

bcachefs: 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]. Additionally, it returns the size of the source string, not the resulting size of the destination string. In an effort to remove strlcpy() completely[2], replace strlcpy() here with strscpy(). Nothing checks the return value here, so a direct replacement with strspy() is possible.

smb3: show beginning time for per share stats
In analyzing problems, one missing piece of debug data is when the mount occurred. A related problem is when collecting stats we don't know the period of time the stats covered, ie when this set of stats for the tcon started to be collected. To make debugging easier track the stats begin time. Set it when the mount occurred at mount time, and reset it to current time whenever stats are reset. For example, ... 1) \\localhost\test SMBs: 14 since 2024-01-17 22:17:30 UTC Bytes read: 0 Bytes written: 0 Open files: 0 total (local), 0 open on server TreeConnects: 1 total 0 failed TreeDisconnects: 0 total 0 failed ... 2) \\localhost\scratch SMBs: 24 since 2024-01-17 22:16:04 UTC Bytes read: 0 Bytes written: 0 Open files: 0 total (local), 0 open on server TreeConnects: 1 total 0 failed TreeDisconnects: 0 total 0 failed ... Note the time "since ... UTC" is now displayed in /proc/fs/cifs/Stats for each share that is mounted.

Driver core changes for 6.8-rc1
Here are the set of driver core and kernfs changes for 6.8-rc1. Nothing
major in here this release cycle, just lots of small cleanups and some
tweaks on kernfs that in the very end, got reverted and will come back
in a safer way next release cycle.
Included in here are:
- more driver core 'const' cleanups and fixes
- fw_devlink=rpm is now the default behavior
- kernfs tiny changes to remove some string functions
- cpu handling in the driver core is updated to work better on many
systems that add topologies and cpus after booting
- other minor changes and cleanups
All of the cpu handling patches have been acked by the respective
maintainers and are coming in here in one series. Everything has been
in linux-next for a while with no reported issues.

Generic:
- Use memdup_array_user() to harden against overflow.
- Unconditionally advertise KVM_CAP_DEVICE_CTRL for all architectures.
- Clean up Kconfigs that all KVM architectures were selecting
- New functionality around "guest_memfd", a new userspace API that
creates an anonymous file and returns a file descriptor that refers
to it. guest_memfd files are bound to their owning virtual machine,
cannot be mapped, read, or written by userspace, and cannot be resized.
guest_memfd files do however support PUNCH_HOLE, which can be used to
switch a memory area between guest_memfd and regular anonymous memory.
- New ioctl KVM_SET_MEMORY_ATTRIBUTES allowing userspace to specify
per-page attributes for a given page of guest memory; right now the
only attribute is whether the guest expects to access memory via
guest_memfd or not, which in Confidential SVMs backed by SEV-SNP,
TDX or ARM64 pKVM is checked by firmware or hypervisor that guarantees
confidentiality (AMD PSP, Intel TDX module, or EL2 in the case of pKVM).
x86:
- Support for "software-protected VMs" that can use the new guest_memfd
and page attributes infrastructure. This is mostly useful for testing,
since there is no pKVM-like infrastructure to provide a meaningfully
reduced TCB.
- Fix a relatively benign off-by-one error when splitting huge pages during
CLEAR_DIRTY_LOG.
- Fix a bug where KVM could incorrectly test-and-clear dirty bits in non-leaf
TDP MMU SPTEs if a racing thread replaces a huge SPTE with a non-huge SPTE.
- Use more generic lockdep assertions in paths that don't actually care
about whether the caller is a reader or a writer.
- let Xen guests opt out of having PV clock reported as "based on a stable TSC",
because some of them don't expect the "TSC stable" bit (added to the pvclock
ABI by KVM, but never set by Xen) to be set.
- Revert a bogus, made-up nested SVM consistency check for TLB_CONTROL.
- Advertise flush-by-ASID support for nSVM unconditionally, as KVM always
flushes on nested transitions, i.e. always satisfies flush requests. This
allows running bleeding edge versions of VMware Workstation on top of KVM.
- Sanity check that the CPU supports flush-by-ASID when enabling SEV support.
- On AMD machines with vNMI, always rely on hardware instead of intercepting
IRET in some cases to detect unmasking of NMIs
- Support for virtualizing Linear Address Masking (LAM)
- Fix a variety of vPMU bugs where KVM fail to stop/reset counters and other state
prior to refreshing the vPMU model.
- Fix a double-overflow PMU bug by tracking emulated counter events using a
dedicated field instead of snapshotting the "previous" counter. If the
hardware PMC count triggers overflow that is recognized in the same VM-Exit
that KVM manually bumps an event count, KVM would pend PMIs for both the
hardware-triggered overflow and for KVM-triggered overflow.
- Turn off KVM_WERROR by default for all configs so that it's not
inadvertantly enabled by non-KVM developers, which can be problematic for
subsystems that require no regressions for W=1 builds.
- Advertise all of the host-supported CPUID bits that enumerate IA32_SPEC_CTRL
"features".
- Don't force a masterclock update when a vCPU synchronizes to the current TSC
generation, as updating the masterclock can cause kvmclock's time to "jump"
unexpectedly, e.g. when userspace hotplugs a pre-created vCPU.
- Use RIP-relative address to read kvm_rebooting in the VM-Enter fault paths,
partly as a super minor optimization, but mostly to make KVM play nice with
position independent executable builds.
- Guard KVM-on-HyperV's range-based TLB flush hooks with an #ifdef on
CONFIG_HYPERV as a minor optimization, and to self-document the code.
- Add CONFIG_KVM_HYPERV to allow disabling KVM support for HyperV "emulation"
at build time.
ARM64:
- LPA2 support, adding 52bit IPA/PA capability for 4kB and 16kB
base granule sizes. Branch shared with the arm64 tree.
- Large Fine-Grained Trap rework, bringing some sanity to the
feature, although there is more to come. This comes with
a prefix branch shared with the arm64 tree.
- Some additional Nested Virtualization groundwork, mostly
introducing the NV2 VNCR support and retargetting the NV
support to that version of the architecture.
- A small set of vgic fixes and associated cleanups.
Loongarch:
- Optimization for memslot hugepage checking
- Cleanup and fix some HW/SW timer issues
- Add LSX/LASX (128bit/256bit SIMD) support
RISC-V:
- KVM_GET_REG_LIST improvement for vector registers
- Generate ISA extension reg_list using macros in get-reg-list selftest
- Support for reporting steal time along with selftest
s390:
- Bugfixes
Selftests:
- Fix an annoying goof where the NX hugepage test prints out garbage
instead of the magic token needed to run the test.
- Fix build errors when a header is delete/moved due to a missing flag
in the Makefile.
- Detect if KVM bugged/killed a selftest's VM and print out a helpful
message instead of complaining that a random ioctl() failed.
- Annotate the guest printf/assert helpers with __printf(), and fix the
various bugs that were lurking due to lack of said annotation.
There are two non-KVM patches buried in the middle of guest_memfd support:
fs: Rename anon_inode_getfile_secure() and anon_inode_getfd_secure()
mm: Add AS_UNMOVABLE to mark mapping as completely unmovable
The first is small and mostly suggested-by Christian Brauner; the second
a bit less so but it was written by an mm person (Vlastimil Babka).

Pull vfs fixes from Christian Brauner:
"This contains two fixes for the current merge window. The listmount
changes that you requested and a fix for a fsnotify performance
regression:
- The proposed listmount changes are currently under my authorship. I
wasn't sure whether you'd wanted to be author as the patch wasn't
signed off. If you do I'm happy if you just apply your own patch.
I've tested the patch with my sh4 cross-build setup. And confirmed
that a) the build failure with sh on current upstream is
reproducible and that b) the proposed patch fixes the build
failure. That should only leave the task of fixing put_user on sh.
- The fsnotify regression was caused by moving one of the hooks out
of the security hook in preparation for other fsnotify work. This
meant that CONFIG_SECURITY would have compiled out the fsnotify
hook before but didn't do so now.
That lead to up to 6% performance regression in some io_uring
workloads that compile all fsnotify and security checks out. Fix
this by making sure that the relevant hooks are covered by the
already existing CONFIG_FANOTIFY_ACCESS_PERMISSIONS where the
relevant hook belongs"

eventfs: Use kcalloc() instead of kzalloc()
As noted in the "Deprecated Interfaces, Language Features, Attributes, and Conventions" documentation [1], size calculations (especially multiplication) should not be performed in memory allocator (or similar) function arguments due to the risk of them overflowing. This could lead to values wrapping around and a smaller allocation being made than the caller was expecting. Using those allocations could lead to linear overflows of heap memory and other misbehaviors. So, use the purpose specific kcalloc() function instead of the argument size * count in the kzalloc() function.

eventfs: Do not create dentries nor inodes in iterate_shared
The original eventfs code added a wrapper around the dcache_readdir open
callback and created all the dentries and inodes at open, and increment
their ref count. A wrapper was added around the dcache_readdir release
function to decrement all the ref counts of those created inodes and
dentries. But this proved to be buggy[1] for when a kprobe was created
during a dir read, it would create a dentry between the open and the
release, and because the release would decrement all ref counts of all
files and directories, that would include the kprobe directory that was
not there to have its ref count incremented in open. This would cause the
ref count to go to negative and later crash the kernel.
To solve this, the dentries and inodes that were created and had their ref
count upped in open needed to be saved. That list needed to be passed from
the open to the release, so that the release would only decrement the ref
counts of the entries that were incremented in the open.
Unfortunately, the dcache_readdir logic was already using the
file->private_data, which is the only field that can be used to pass
information from the open to the release. What was done was the eventfs
created another descriptor that had a void pointer to save the
dcache_readdir pointer, and it wrapped all the callbacks, so that it could
save the list of entries that had their ref counts incremented in the
open, and pass it to the release. The wrapped callbacks would just put
back the dcache_readdir pointer and call the functions it used so it could
still use its data[2].
But Linus had an issue with the "hijacking" of the file->private_data
(unfortunately this discussion was on a security list, so no public link).
Which we finally agreed on doing everything within the iterate_shared
callback and leave the dcache_readdir out of it[3]. All the information
needed for the getents() could be created then.
But this ended up being buggy too[4]. The iterate_shared callback was not
the right place to create the dentries and inodes. Even Christian Brauner
had issues with that[5].
An attempt was to go back to creating the inodes and dentries at
the open, create an array to store the information in the
file->private_data, and pass that information to the other callbacks.[6]
The difference between that and the original method, is that it does not
use dcache_readdir. It also does not up the ref counts of the dentries and
pass them. Instead, it creates an array of a structure that saves the
dentry's name and inode number. That information is used in the
iterate_shared callback, and the array is freed in the dir release. The
dentries and inodes created in the open are not used for the iterate_share
or release callbacks. Just their names and inode numbers.
Linus did not like that either[7] and just wanted to remove the dentries
being created in iterate_shared and use the hard coded inode numbers.
[ All this while Linus enjoyed an unexpected vacation during the merge
window due to lack of power. ]

eventfs: Have the inodes all for files and directories all be the same
The dentries and inodes are created in the readdir for the sole purpose of getting a consistent inode number. Linus stated that is unnecessary, and that all inodes can have the same inode number. For a virtual file system they are pretty meaningless. Instead use a single unique inode number for all files and one for all directories.

f2fs update for 6.8-rc1
In this series, we've some progress to support Zoned block device regarding to
the power-cut recovery flow and enabling checkpoint=disable feature which is
essential for Android OTA. Other than that, some patches touched sysfs entries
and tracepoints which are minor, while several bug fixes on error handlers and
compression flows are good to improve the overall stability.
Enhancement:
- enable checkpoint=disable for zoned block device
- sysfs entries such as discard status, discard_io_aware, dir_level
- tracepoints such as f2fs_vm_page_mkwrite(), f2fs_rename(), f2fs_new_inode()
- use shared inode lock during f2fs_fiemap() and f2fs_seek_block()
Bug fix:
- address some power-cut recovery issues on zoned block device
- handle errors and logics on do_garbage_collect(), f2fs_reserve_new_block(),
f2fs_move_file_range(), f2fs_recover_xattr_data()
- don't set FI_PREALLOCATED_ALL for partial write
- fix to update iostat correctly in f2fs_filemap_fault()
- fix to wait on block writeback for post_read case
- fix to tag gcing flag on page during block migration
- restrict max filesize for 16K f2fs
- fix to avoid dirent corruption
- explicitly null-terminate the xattr list
There are also several clean-up patches to remove dead codes and better
readability.

Another moderately busy cycle for documentation, including:
- The minimum Sphinx requirement has been raised to 2.4.4, following a
warning that was added in 6.2.
- Some reworking of the Documentation/process front page to, hopefully,
make it more useful.
- Various kernel-doc tweaks to, for example, make it deal properly with
__counted_by annotations.
- We have also restored a warning for documentation of nonexistent
structure members that disappeared a while back. That had the delightful
consequence of adding some 600 warnings to the docs build. A sustained
effort by Randy, Vegard, and myself has addressed almost all of those,
bringing the documentation back into sync with the code. The fixes are
going through the appropriate maintainer trees.
- Various improvements to the HTML rendered docs, including automatic links
to Git revisions and a nice new pulldown to make translations easy to
access.
- Speaking of translations, more of those for Spanish and Chinese.
...plus the usual stream of documentation updates and typo fixes.

Networking changes for 6.8.
Core & protocols
----------------
- Analyze and reorganize core networking structs (socks, netdev,
netns, mibs) to optimize cacheline consumption and set up
build time warnings to safeguard against future header changes.
This improves TCP performances with many concurrent connections
up to 40%.
- Add page-pool netlink-based introspection, exposing the
memory usage and recycling stats. This helps indentify
bad PP users and possible leaks.
- Refine TCP/DCCP source port selection to no longer favor even
source port at connect() time when IP_LOCAL_PORT_RANGE is set.
This lowers the time taken by connect() for hosts having
many active connections to the same destination.
- Refactor the TCP bind conflict code, shrinking related socket
structs.
- Refactor TCP SYN-Cookie handling, as a preparation step to
allow arbitrary SYN-Cookie processing via eBPF.
- Tune optmem_max for 0-copy usage, increasing the default value
to 128KB and namespecifying it.
- Allow coalescing for cloned skbs coming from page pools, improving
RX performances with some common configurations.
- Reduce extension header parsing overhead at GRO time.
- Add bridge MDB bulk deletion support, allowing user-space to
request the deletion of matching entries.
- Reorder nftables struct members, to keep data accessed by the
datapath first.
- Introduce TC block ports tracking and use. This allows supporting
multicast-like behavior at the TC layer.
- Remove UAPI support for retired TC qdiscs (dsmark, CBQ and ATM) and
classifiers (RSVP and tcindex).
- More data-race annotations.
- Extend the diag interface to dump TCP bound-only sockets.
- Conditional notification of events for TC qdisc class and actions.
- Support for WPAN dynamic associations with nearby devices, to form
a sub-network using a specific PAN ID.
- Implement SMCv2.1 virtual ISM device support.
- Add support for Batman-avd mulicast packet type.
BPF
---
- Tons of verifier improvements:
- BPF register bounds logic and range support along with a large
test suite
- log improvements
- complete precision tracking support for register spills
- track aligned STACK_ZERO cases as imprecise spilled registers. It
improves the verifier "instructions processed" metric from single
digit to 50-60% for some programs
- support for user's global BPF subprogram arguments with few
commonly requested annotations for a better developer experience
- support tracking of BPF_JNE which helps cases when the compiler
transforms (unsigned) "a > 0" into "if a == 0 goto xxx" and the
like
- several fixes
- Add initial TX metadata implementation for AF_XDP with support in
mlx5 and stmmac drivers. Two types of offloads are supported right
now, that is, TX timestamp and TX checksum offload.
- Fix kCFI bugs in BPF all forms of indirect calls from BPF into
kernel and from kernel into BPF work with CFI enabled. This allows
BPF to work with CONFIG_FINEIBT=y.
- Change BPF verifier logic to validate global subprograms lazily
instead of unconditionally before the main program, so they can be
guarded using BPF CO-RE techniques.
- Support uid/gid options when mounting bpffs.
- Add a new kfunc which acquires the associated cgroup of a task
within a specific cgroup v1 hierarchy where the latter is identified
by its id.
- Extend verifier to allow bpf_refcount_acquire() of a map value field
obtained via direct load which is a use-case needed in sched_ext.
- Add BPF link_info support for uprobe multi link along with bpftool
integration for the latter.
- Support for VLAN tag in XDP hints.
- Remove deprecated bpfilter kernel leftovers given the project
is developed in user-space (https://github.com/facebook/bpfilter).
Misc
----
- Support for parellel TC self-tests execution.
- Increase MPTCP self-tests coverage.
- Updated the bridge documentation, including several so-far
undocumented features.
- Convert all the net self-tests to run in unique netns, to
avoid random failures due to conflict and allow concurrent
runs.
- Add TCP-AO self-tests.
- Add kunit tests for both cfg80211 and mac80211.
- Autogenerate Netlink families documentation from YAML spec.
- Add yml-gen support for fixed headers and recursive nests, the
tool can now generate user-space code for all genetlink families
for which we have specs.
- A bunch of additional module descriptions fixes.
- Catch incorrect freeing of pages belonging to a page pool.
Driver API
----------
- Rust abstractions for network PHY drivers; do not cover yet the
full C API, but already allow implementing functional PHY drivers
in rust.
- Introduce queue and NAPI support in the netdev Netlink interface,
allowing complete access to the device <> NAPIs <> queues
relationship.
- Introduce notifications filtering for devlink to allow control
application scale to thousands of instances.
- Improve PHY validation, requesting rate matching information for
each ethtool link mode supported by both the PHY and host.
- Add support for ethtool symmetric-xor RSS hash.

Merge tag 'net-next-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Paolo Abeni:
"The most interesting thing is probably the networking structs
reorganization and a significant amount of changes is around
self-tests.
Core & protocols:
- Analyze and reorganize core networking structs (socks, netdev,
netns, mibs) to optimize cacheline consumption and set up build
time warnings to safeguard against future header changes
This improves TCP performances with many concurrent connections up
to 40%
- Add page-pool netlink-based introspection, exposing the memory
usage and recycling stats. This helps indentify bad PP users and
possible leaks
- Refine TCP/DCCP source port selection to no longer favor even
source port at connect() time when IP_LOCAL_PORT_RANGE is set. This
lowers the time taken by connect() for hosts having many active
connections to the same destination
- Refactor the TCP bind conflict code, shrinking related socket
structs
- Refactor TCP SYN-Cookie handling, as a preparation step to allow
arbitrary SYN-Cookie processing via eBPF
- Tune optmem_max for 0-copy usage, increasing the default value to
128KB and namespecifying it
- Allow coalescing for cloned skbs coming from page pools, improving
RX performances with some common configurations
- Reduce extension header parsing overhead at GRO time
- Add bridge MDB bulk deletion support, allowing user-space to
request the deletion of matching entries
- Reorder nftables struct members, to keep data accessed by the
datapath first
- Introduce TC block ports tracking and use. This allows supporting
multicast-like behavior at the TC layer
- Remove UAPI support for retired TC qdiscs (dsmark, CBQ and ATM) and
classifiers (RSVP and tcindex)
- More data-race annotations
- Extend the diag interface to dump TCP bound-only sockets
- Conditional notification of events for TC qdisc class and actions
- Support for WPAN dynamic associations with nearby devices, to form
a sub-network using a specific PAN ID
- Implement SMCv2.1 virtual ISM device support
- Add support for Batman-avd mulicast packet type
BPF:
- Tons of verifier improvements:
- BPF register bounds logic and range support along with a large
test suite
- log improvements
- complete precision tracking support for register spills
- track aligned STACK_ZERO cases as imprecise spilled registers.
This improves the verifier "instructions processed" metric from
single digit to 50-60% for some programs
- support for user's global BPF subprogram arguments with few
commonly requested annotations for a better developer
experience
- support tracking of BPF_JNE which helps cases when the compiler
transforms (unsigned) "a > 0" into "if a == 0 goto xxx" and the
like
- several fixes
- Add initial TX metadata implementation for AF_XDP with support in
mlx5 and stmmac drivers. Two types of offloads are supported right
now, that is, TX timestamp and TX checksum offload
- Fix kCFI bugs in BPF all forms of indirect calls from BPF into
kernel and from kernel into BPF work with CFI enabled. This allows
BPF to work with CONFIG_FINEIBT=y
- Change BPF verifier logic to validate global subprograms lazily
instead of unconditionally before the main program, so they can be
guarded using BPF CO-RE techniques
- Support uid/gid options when mounting bpffs
- Add a new kfunc which acquires the associated cgroup of a task

Revert "kernfs: convert kernfs_idr_lock to an irq safe raw spinlock"
This reverts commit dad3fb67ca1cbef87ce700e83a55835e5921ce8a. The commit converted kernfs_idr_lock to an IRQ-safe raw_spinlock because it could be acquired while holding an rq lock through bpf_cgroup_from_id(). However, kernfs_idr_lock is held while doing GPF_NOWAIT allocations which involves acquiring an non-IRQ-safe and non-raw lock leading to the following lockdep warning: ============================= [ BUG: Invalid wait context ] 6.7.0-rc5-kzm9g-00251-g655022a45b1c #578 Not tainted ----------------------------- swapper/0/0 is trying to lock: dfbcd488 (&c->lock){....}-{3:3}, at: local_lock_acquire+0x0/0xa4 other info that might help us debug this: context-{5:5} 2 locks held by swapper/0/0: #0: dfbc9c60 (lock){+.+.}-{3:3}, at: local_lock_acquire+0x0/0xa4 #1: c0c012a8 (kernfs_idr_lock){....}-{2:2}, at: __kernfs_new_node.constprop.0+0x68/0x258 stack backtrace: CPU: 0 PID: 0 Comm: swapper/0 Not tainted 6.7.0-rc5-kzm9g-00251-g655022a45b1c #578 Hardware name: Generic SH73A0 (Flattened Device Tree) unwind_backtrace from show_stack+0x10/0x14 show_stack from dump_stack_lvl+0x68/0x90 dump_stack_lvl from __lock_acquire+0x3cc/0x168c __lock_acquire from lock_acquire+0x274/0x30c lock_acquire from local_lock_acquire+0x28/0xa4 local_lock_acquire from ___slab_alloc+0x234/0x8a8 ___slab_alloc from __slab_alloc.constprop.0+0x30/0x44 __slab_alloc.constprop.0 from kmem_cache_alloc+0x7c/0x148 kmem_cache_alloc from radix_tree_node_alloc.constprop.0+0x44/0xdc radix_tree_node_alloc.constprop.0 from idr_get_free+0x110/0x2b8 idr_get_free from idr_alloc_u32+0x9c/0x108 idr_alloc_u32 from idr_alloc_cyclic+0x50/0xb8 idr_alloc_cyclic from __kernfs_new_node.constprop.0+0x88/0x258 __kernfs_new_node.constprop.0 from kernfs_create_root+0xbc/0x154 kernfs_create_root from sysfs_init+0x18/0x5c sysfs_init from mnt_init+0xc4/0x220 mnt_init from vfs_caches_init+0x6c/0x88 vfs_caches_init from start_kernel+0x474/0x528 start_kernel from 0x0 Let's rever the commit.

sysctl-6.8-rc1
To help make the move of sysctls out of kernel/sysctl.c not incur a size
penalty sysctl has been changed to allow us to not require the sentinel, the
final empty element on the sysctl array. Joel Granados has been doing all this
work. On the v6.6 kernel we got the major infrastructure changes required to
support this. For v6.7 we had all arch/ and drivers/ modified to remove
the sentinel. For v6.8-rc1 we get a few more updates for fs/ directory only.
The kernel/ directory is left but we'll save that for v6.9-rc1 as those patches
are still being reviewed. After that we then can expect also the removal of the
no longer needed check for procname == NULL.
Let us recap the purpose of this work:
- this helps reduce the overall build time size of the kernel and run time
memory consumed by the kernel by about ~64 bytes per array
- the extra 64-byte penalty is no longer inncurred now when we move sysctls
out from kernel/sysctl.c to their own files
Thomas Weißschuh also sent a few cleanups, for v6.9-rc1 we expect to see further
work by Thomas Weißschuh with the constificatin of the struct ctl_table.
Due to Joel Granados's work, and to help bring in new blood, I have suggested
for him to become a maintainer and he's accepted. So for v6.9-rc1 I look forward
to seeing him sent you a pull request for further sysctl changes. This also
removes Iurii Zaikin as a maintainer as he has moved on to other projects and
has had no time to help at all.

header cleanups for 6.8
The goal is to get sched.h down to a type only header, so the main thing happening in this patchset is splitting out various _types.h headers and dependency fixups, as well as moving some things out of sched.h to better locations. This is prep work for the memory allocation profiling patchset which adds new sched.h interdepencencies.

bcachefs updates for 6.8:
- btree write buffer rewrite: instead of adding keys to the btree write
buffer at transaction commit time, we know journal them with a
different journal entry type and copy them from the journal to the
write buffer just prior to journal write.
This reduces the number of atomic operations on shared cachelines
in the transaction commit path and is a signicant performance
improvement on some workloads: multithreaded 4k random writes went
from ~650k iops to ~850k iops.
- Bring back optimistic spinning for six locks: the new implementation
doesn't use osq locks; instead we add to the lock waitlist as normal,
and then spin on the lock_acquired bit in the waitlist entry, _not_
the lock itself.
- BCH_IOCTL_DEV_USAGE_V2, which allows for new data types
- BCH_IOCTL_OFFLINE_FSCK, which runs the kernel implementation of fsck
but without mounting: useful for transparently using the kernel
version of fsck from 'bcachefs fsck' when the kernel version is a
better match for the on disk filesystem.
- BCH_IOCTL_ONLINE_FSCK: online fsck. Not all passes are supported yet,
but the passes that are supported are fully featured - errors may be
corrected as normal.
The new ioctls use the new 'thread_with_file' abstraction for kicking
off a kthread that's tied to a file descriptor returned to userspace
via the ioctl.
- btree_paths within a btree_trans are now dynamically growable,
instead of being limited to 64. This is important for the
check_directory_structure phase of fsck, and also fixes some issues
we were having with btree path overflow in the reflink btree.
- Trigger refactoring; prep work for the upcoming disk space accounting
rewrite
- Numerous bugfixes :)

ext4: fix inconsistent between segment fstrim and full fstrim
Suppose we issue two FITRIM ioctls for ranges [0,15] and [16,31] with mininum length of trimmed range set to 8 blocks. If we have say a range of blocks 10-22 free, this range will not be trimmed because it straddles the boundary of the two FITRIM ranges and neither part is big enough. This is a bit surprising to some users that call FITRIM on smaller ranges of blocks to limit impact on the system. Also XFS trims all free space extents that overlap with the specified range so we are inconsistent among filesystems. Let's change ext4_try_to_trim_range() to consider for trimming the whole free space extent that straddles the end of specified range, not just the part of it within the range.

In case we are not able to find any, we again go back to calling ext4_mb_choose_next_group() to search for a different suitable block group. However, since the linear search always begins from the start, most of the times we end up with the same BG and the cycle continues. With large fliesystems, the CPU can be stuck in this loop for hours which can slow down the whole system. Hence, until we figure out a better way to continue the search (rather than starting from beginning) in ext4_mb_choose_next_group(), lets just fallback to ext4_mb_complex_scan_group() in case aligned scan fails, as it is much more likely to find the needed blocks.

ext4: convert ext4_da_do_write_end() to take a folio
There's nothing page-specific happening in ext4_da_do_write_end(); it's merely used for its refcount & lock, both of which are folio properties. Saves four calls to compound_head().

ext4: allow for the last group to be marked as trimmed
The ext4 filesystem tracks the trim status of blocks at the group
level. When an entire group has been trimmed then it is marked as
such and subsequent trim invocations with the same minimum trim size
will not be attempted on that group unless it is marked as able to be
trimmed again such as when a block is freed.
Currently the last group can't be marked as trimmed due to incorrect
logic in ext4_last_grp_cluster(). ext4_last_grp_cluster() is supposed
to return the zero based index of the last cluster in a group. This is
then used by ext4_try_to_trim_range() to determine if the trim
operation spans the entire group and as such if the trim status of the
group should be recorded.
ext4_last_grp_cluster() takes a 0 based group index, thus the valid
values for grp are 0..(ext4_get_groups_count - 1). Any group index
less than (ext4_get_groups_count - 1) is not the last group and must
have EXT4_CLUSTERS_PER_GROUP(sb) clusters. For the last group we need
to calculate the number of clusters based on the number of blocks in
the group. Finally subtract 1 from the number of clusters as zero
based indexing is expected. Rearrange the function slightly to make
it clear what we are calculating and returning.
Reproducer:
// Create file system where the last group has fewer blocks than
// blocks per group
$ mkfs.ext4 -b 4096 -g 8192 /dev/nvme0n1 8191
$ mount /dev/nvme0n1 /mnt
Before Patch:
$ fstrim -v /mnt
/mnt: 25.9 MiB (27156480 bytes) trimmed
// Group not marked as trimmed so second invocation still discards blocks
$ fstrim -v /mnt
/mnt: 25.9 MiB (27156480 bytes) trimmed
After Patch:
fstrim -v /mnt
/mnt: 25.9 MiB (27156480 bytes) trimmed
// Group marked as trimmed so second invocation DOESN'T discard any blocks
fstrim -v /mnt
/mnt: 0 B (0 bytes) trimmed

There is one significant revert to mention: support for RDMA Read operations in the server's RPC-over-RDMA transport implementation has been fixed so it waits for Read completion in a way that avoids tying up an nfsd thread.

Pull afs updates from David Howells:
"The majority of the patches are aimed at fixing and improving the AFS
filesystem's rotation over server IP addresses, but there are also
some fixes from Oleg Nesterov for the use of read_seqbegin_or_lock().
- Fix fileserver probe handling so that the next round of probes
doesn't break ongoing server/address rotation by clearing all the
probe result tracking. This could occasionally cause the rotation
algorithm to drop straight through, give a 'successful' result
without actually emitting any RPC calls, leaving the reply buffer
in an undefined state.
Instead, detach the probe results into a separate struct and
allocate a new one each time we start probing and update the
pointer to it. Probes are also sent in order of address preference
to try and improve the chance that the preferred one will complete
first.
- Fix server rotation so that it uses configurable address
preferences across on the probes that have completed so far than
ranking them by RTT as the latter doesn't necessarily give the best
route. The preference list can be altered by writing into
/proc/net/afs/addr_prefs.
- Fix the handling of Read-Only (and Backup) volume callbacks as
there is one per volume, not one per file, so if someone performs a
command that, say, offlines the volume but doesn't change it, when
it comes back online we don't spam the server with a status fetch
for every vnode we're using. Instead, check the Creation timestamp
in the VolSync record when prompted by a callback break.
- Handle volume regression (ie. a RW volume being restored from a
backup) by scrubbing all cache data for that volume. This is
detected from the VolSync creation timestamp.
- Adjust abort handling and abort -> error mapping to match better
with what other AFS clients do.
- Fix offline and busy volume state handling as they only apply to
individual server instances and not entire volumes and the rotation
algorithm should go and look at other servers if available. Also
make it sleep briefly before each retry if all the volume instances
are unavailable"

Pull btrfs updates from David Sterba:
"There are no exciting changes for users, it's been mostly API
conversions and some fixes or refactoring.
The mount API conversion is a base for future improvements that would
come with VFS. Metadata processing has been converted to folios, not
yet enabling the large folios but it's one patch away once everything
gets tested enough.
Core changes:
- convert extent buffers to folios:
- direct API conversion where possible
- performance can drop by a few percent on metadata heavy
workloads, the folio sizes are not constant and the calculations
add up in the item helpers
- both regular and subpage modes
- data cannot be converted yet, we need to port that to iomap and
there are some other generic changes required
- convert mount to the new API, should not be user visible:
- options deprecated long time ago have been removed: inode_cache,
recovery
- the new logic that splits mount to two phases slightly changes
timing of device scanning for multi-device filesystems
- LSM options will now work (like for selinux)
- convert delayed nodes radix tree to xarray, preserving the
preload-like logic that still allows to allocate with GFP_NOFS
- more validation of sysfs value of scrub_speed_max
- refactor chunk map structure, reduce size and improve performance
- extent map refactoring, smaller data structures, improved
performance
- reduce size of struct extent_io_tree, embedded in several
structures
- temporary pages used for compression are cached and attached to a
shrinker, this may slightly improve performance
- in zoned mode, remove redirty extent buffer tracking, zeros are
written in case an out-of-order is detected and proper data are
written to the actual write pointer
- cleanups, refactoring, error message improvements, updated tests
- verify and update branch name or tag
- remove unwanted text"

New code for 6.8:
* New features/functionality
* Online repair
* Reserve disk space for online repairs.
* Fix misinteraction between the AIL and btree bulkloader because of
which the bulk load fails to queue a buffer for writeback if it
happens to be on the AIL list.
* Prevent transaction reservation overflows when reaping blocks during
online repair.
* Whenever possible, bulkloader now copies multiple records into a
block.
* Support repairing of
1. Per-AG free space, inode and refcount btrees.
2. Ondisk inodes.
3. File data and attribute fork mappings.
* Verify the contents of
1. Inode and data fork of realtime bitmap file.
2. Quota files.
* Introduce MF_MEM_PRE_REMOVE. This will be used to notify tasks about
a pmem device being removed.
* Bug fixes
* Fix memory leak of recovered attri intent items.
* Fix UAF during log intent recovery.
* Fix realtime geometry integer overflows.
* Prevent scrub from live locking in xchk_iget.
* Prevent fs shutdown when removing files during low free disk space.
* Prevent transaction reservation overflow when extending an RT device.
* Prevent incorrect warning from being printed when extending a
filesystem.
* Fix an off-by-one error in xreap_agextent_binval.
* Serialize access to perag radix tree during deletion operation.
* Fix perag memory leak during growfs.
* Allow allocation of minlen realtime extent when the maximum sized
realtime free extent is minlen in size.
* Cleanups
* Remove duplicate boilerplate code spread across functionality associated
with different log items.
* Cleanup resblks interfaces.
* Pass defer ops pointer to defer helpers instead of an enum.
* Initialize di_crc in xfs_log_dinode to prevent KMSAN warnings.
* Use static_assert() instead of BUILD_BUG_ON_MSG() to validate size of
structures and structure member offsets. This is done in order to be
able to share the code with userspace.
* Move XFS documentation under a new directory specific to XFS.
* Do not invoke deferred ops' ->create_done callback if the deferred
operation does not have an intent item associated with it.
* Remove duplicate inclusion of header files from scrub/health.c.
* Refactor Realtime code.
* Cleanup attr code.

The kernel thread function ksmbd_conn_handler_loop() invokes the try_to_freeze() in its loop. But all the kernel threads are non-freezable by default. So if we want to make a kernel thread to be freezable, we have to invoke set_freezable() explicitly.
