sysctl changes for v6.10-rc1
Summary
* Removed sentinel elements from ctl_table structs in kernel/*
Removing sentinels in ctl_table arrays reduces the build time size and
runtime memory consumed by ~64 bytes per array. Removals for net/, io_uring/,
mm/, ipc/ and security/ are set to go into mainline through their respective
subsystems making the next release the most likely place where the final
series that removes the check for proc_name == NULL will land. This PR adds
to removals already in arch/, drivers/ and fs/.
* Adjusted ctl_table definitions and references to allow constification
Adjustments:
- Removing unused ctl_table function arguments
- Moving non-const elements from ctl_table to ctl_table_header
- Making ctl_table pointers const in ctl_table_root structure
Making the static ctl_table structs const will increase safety by keeping the
pointers to proc_handler functions in .rodata. Though no ctl_tables where
made const in this PR, the ground work for making that possible has started
with these changes sent by Thomas Weißschuh.
Testing
* These changes went into linux-next after v6.9-rc4; giving it a good month of
testing.

Networking changes for 6.10.
Core & protocols
----------------
- Complete rework of garbage collection of AF_UNIX sockets.
AF_UNIX is prone to forming reference count cycles due to fd passing
functionality. New method based on Tarjan's Strongly Connected Components
algorithm should be both faster and remove a lot of workarounds
we accumulated over the years.
- Add TCP fraglist GRO support, allowing chaining multiple TCP packets
and forwarding them together. Useful for small switches / routers which
lack basic checksum offload in some scenarios (e.g. PPPoE).
- Support using SMP threads for handling packet backlog i.e. packet
processing from software interfaces and old drivers which don't
use NAPI. This helps move the processing out of the softirq jumble.
- Continue work of converting from rtnl lock to RCU protection.
Don't require rtnl lock when reading: IPv6 routing FIB, IPv6 address
labels, netdev threaded NAPI sysfs files, bonding driver's sysfs files,
MPLS devconf, IPv4 FIB rules, netns IDs, tcp metrics, TC Qdiscs,
neighbor entries, ARP entries via ioctl(SIOCGARP), a lot of the link
information available via rtnetlink.
- Small optimizations from Eric to UDP wake up handling, memory accounting,
RPS/RFS implementation, TCP packet sizing etc.
- Allow direct page recycling in the bulk API used by XDP, for +2% PPS.
- Support peek with an offset on TCP sockets.
- Add MPTCP APIs for querying last time packets were received/sent/acked,
and whether MPTCP "upgrade" succeeded on a TCP socket.
- Add intra-node communication shortcut to improve SMC performance.
- Add IPv6 (and IPv{4,6}-over-IPv{4,6}) support to the GTP protocol driver.
- Add HSR-SAN (RedBOX) mode of operation to the HSR protocol driver.
- Add reset reasons for tracing what caused a TCP reset to be sent.
- Introduce direction attribute for xfrm (IPSec) states.
State can be used either for input or output packet processing.
Things we sprinkled into general kernel code
--------------------------------------------
- Add bitmap_{read,write}(), bitmap_size(), expose BYTES_TO_BITS().
This required touch-ups and renaming of a few existing users.
- Add Endian-dependent __counted_by_{le,be} annotations.
- Make building selftests "quieter" by printing summaries like
"CC object.o" rather than full commands with all the arguments.
Netfilter
---------
- Use GFP_KERNEL to clone elements, to deal better with OOM situations
and avoid failures in the .commit step.
BPF
---
- Add eBPF JIT for ARCv2 CPUs.
- Support attaching kprobe BPF programs through kprobe_multi link in
a session mode, meaning, a BPF program is attached to both function entry
and return, the entry program can decide if the return program gets
executed and the entry program can share u64 cookie value with return
program. "Session mode" is a common use-case for tetragon and bpftrace.
- Add the ability to specify and retrieve BPF cookie for raw tracepoint
programs in order to ease migration from classic to raw tracepoints.
- Add an internal-only BPF per-CPU instruction for resolving per-CPU
memory addresses and implement support in x86, ARM64 and RISC-V JITs.
This allows inlining functions which need to access per-CPU state.
- Optimize x86 BPF JIT's emit_mov_imm64, and add support for various
atomics in bpf_arena which can be JITed as a single x86 instruction.
Support BPF arena on ARM64.
- Add a new bpf_wq API for deferring events and refactor process-context
bpf_timer code to keep common code where possible.
- Harden the BPF verifier's and/or/xor value tracking.
- Introduce crypto kfuncs to let BPF programs call kernel crypto APIs.
- Support bpf_tail_call_static() helper for BPF programs with GCC 13.
- Add bpf_preempt_{disable,enable}() kfuncs in order to allow a BPF
program to have code sections where preemption is disabled.
Driver API
----------
- Skip software TC processing completely if all installed rules are
marked as HW-only, instead of checking the HW-only flag rule by rule.
- Add support for configuring PoE (Power over Ethernet), similar to
the already existing support for PoDL (Power over Data Line) config.
- Initial bits of a queue control API, for now allowing a single queue
to be reset without disturbing packet flow to other queues.
- Common (ethtool) statistics for hardware timestamping.
Tests and tooling
-----------------
- Remove the need to create a config file to run the net forwarding tests
so that a naive "make run_tests" can exercise them.
- Define a method of writing tests which require an external endpoint
to communicate with (to send/receive data towards the test machine).
Add a few such tests.
- Create a shared code library for writing Python tests. Expose the YAML
Netlink library from tools/ to the tests for easy Netlink access.
- Move netfilter tests under net/, extend them, separate performance tests
from correctness tests, and iron out issues found by running them
"on every commit".
- Refactor BPF selftests to use common network helpers.
- Further work filling in YAML definitions of Netlink messages for:
nftables, team driver, bonding interfaces, vlan interfaces, VF info,
TC u32 mark, TC police action.
- Teach Python YAML Netlink to decode attribute policies.
- Extend the definition of the "indexed array" construct in the specs
to cover arrays of scalars rather than just nests.
- Add hyperlinks between definitions in generated Netlink docs.
Drivers
-------
- Make sure unsupported flower control flags are rejected by drivers,
and make more drivers report errors directly to the application rather
than dmesg (large number of driver changes from Asbjørn Sloth Tønnesen).
- Ethernet high-speed NICs:
- Broadcom (bnxt):

dlm for 6.10
- Fix a long standing race between the unlock callback for the last lkb
struct, and removing the rsb that became unused after the final unlock.
This could lead different nodes to inconsistent info about the rsb master
node.
- Remove unnecessary refcounting on callback structs, returning to the way
things were done in the past.
- Do message processing in softirq context. This allows dlm messages to
be cleared more quickly and efficiently, reducing long lists of incomplete
requests. A future change to run callbacks directly from this context
will make this more effective.
- The softirq message processing involved a number of patches changing
mutexes to spinlocks and rwlocks, and a fair amount of code re-org in
preparation.
- Use an rhashtable for rsb structs, rather than our old internal hash
table implementation. This also required some re-org of lists and locks
preparation for the change.
- Drop the dlm_scand kthread, and use timers to clear unused rsb structs.
Scanning all rsb's periodically was a lot of wasted work.
- Fix recent regression in logic for copying LVB data in user space lock
requests.

Pull btrfs updates from David Sterba:
"This update brings a few minor performance improvements, otherwise
there's a lot of refactoring, cleanups and other sort of not user
visible changes.
Performance improvements:
- inline b-tree locking functions, improvement in metadata-heavy
changes
- relax locking on a range that's being reflinked, allows read
operations to run in parallel
- speed up NOCOW write checks (throughput +9% on a sample test)
- extent locking ranges have been reduced in several places, namely
around delayed ref processing
Core:
- more page to folio conversions:
- relocation
- send
- compression
- inline extent handling
- super block write and wait
- extent_map structure optimizations:
- reduced structure size
- code simplifications
- add shrinker for allocated objects, the numbers can go high and
could exhaust memory on smaller systems (reported) as they may
not get an opportunity to be freed fast enough
- extent locking optimizations:
- reduce locking ranges where it does not seem to be necessary and
are safe due to other means of synchronization
- potential improvements due to lower contention,
allocation/freeing and state management operations of extent
state tracking structures
- delayed ref cleanups and simplifications
- updated trace points
- improved error handling, warnings and assertions
- cleanups and refactoring, unification of error handling paths"

smb3: fix perf regression with cached writes with netfs conversion
Write through mode is for cache=none, not for default (when
caching is allowed if we have a lease). Some tests were running
much, much more slowly as a result of disabling caching of
writes by default.

eventfs: Fix a possible null pointer dereference in eventfs_find_events()
In function eventfs_find_events,there is a potential null pointer
that may be caused by calling update_events_attr which will perform
some operations on the members of the ei struct when ei is NULL.
Hence,When ei->is_freed is set,return NULL directly.

smb: smb2pdu.h: Avoid -Wflex-array-member-not-at-end warnings
-Wflex-array-member-not-at-end is coming in GCC-14, and we are getting ready to enable it globally. So, in order to avoid ending up with a flexible-array member in the middle of multiple other structs, we use the `__struct_group()` helper to separate the flexible array from the rest of the members in the flexible structure, and use the tagged `struct create_context_hdr` instead of `struct create_context`. So, with these changes, fix 51 of the following warnings[1]: fs/smb/client/../common/smb2pdu.h:1225:31: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] Link: https://gist.github.com/GustavoARSilva/772526a39be3dd4db39e71497f0a9893 [1] Link: https://github.com/KSPP/linux/issues/202 Signed-off-by: Gustavo A.

Merge tag 'hardening-6.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
Pull hardening updates from Kees Cook:
"The bulk of the changes here are related to refactoring and expanding
the KUnit tests for string helper and fortify behavior.
Some trivial strncpy replacements in fs/ were carried in my tree. Also
some fixes to SCSI string handling were carried in my tree since the
helper for those was introduce here. Beyond that, just little fixes
all around: objtool getting confused about LKDTM+KCFI, preparing for
future refactors (constification of sysctl tables, additional
__counted_by annotations), a Clang UBSAN+i386 crash fix, and adding
more options in the hardening.config Kconfig fragment.
Summary:
- selftests: Add str*cmp tests (Ivan Orlov)
- __counted_by: provide UAPI for _le/_be variants (Erick Archer)
- Various strncpy deprecation refactors (Justin Stitt)
- stackleak: Use a copy of soon-to-be-const sysctl table (Thomas

Merge tag 'vfs-6.10.netfs' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull netfs updates from Christian Brauner:
"This reworks the netfslib writeback implementation so that pages read
from the cache are written to the cache through ->writepages(),
thereby allowing the fscache page flag to be retired.
The reworking also:
- builds on top of the new writeback_iter() infrastructure
- makes it possible to use vectored write RPCs as discontiguous
streams of pages can be accommodated
- makes it easier to do simultaneous content crypto and stream
division
- provides support for retrying writes and re-dividing a stream
- replaces the ->launder_folio() op, so that ->writepages() is used
instead
- uses mempools to allocate the netfs_io_request and
netfs_io_subrequest structs to avoid allocation failure in the
writeback path
Some code that uses the fscache page flag is retained for
compatibility purposes with nfs and ceph. The code is switched to
using the synonymous private_2 label instead and marked with
deprecation comments.
The merge commit contains additional details on the new algorithm that
I've left out of here as it would probably be excessively detailed.
On top of the netfslib infrastructure this contains the work to
convert cifs over to netfslib"

Pull misc vfs updates from Christian Brauner:
"This contains the usual miscellaneous features, cleanups, and fixes
for vfs and individual fses.
Features:
- Free up FMODE_* bits. I've freed up bits 6, 7, 8, and 24. That
means we now have six free FMODE_* bits in total (but bit #6
already got used for FMODE_WRITE_RESTRICTED)
- Add FOP_HUGE_PAGES flag (follow-up to FMODE_* cleanup)
- Add fd_raw cleanup class so we can make use of automatic cleanup
provided by CLASS(fd_raw, f)(fd) for O_PATH fds as well
- Optimize seq_puts()
- Simplify __seq_puts()
- Add new anon_inode_getfile_fmode() api to allow specifying f_mode
instead of open-coding it in multiple places
- Annotate struct file_handle with __counted_by() and use
struct_size()
- Warn in get_file() whether f_count resurrection from zero is
attempted (epoll/drm discussion)
- Folio-sophize aio
- Export the subvolume id in statx() for both btrfs and bcachefs
- Relax linkat(AT_EMPTY_PATH) requirements
- Add F_DUPFD_QUERY fcntl() allowing to compare two file descriptors
for dup*() equality replacing kcmp()
Cleanups:
- Compile out swapfile inode checks when swap isn't enabled
- Use (1 << n) notation for FMODE_* bitshifts for clarity
- Remove redundant variable assignment in fs/direct-io
- Cleanup uses of strncpy in orangefs
- Speed up and cleanup writeback
- Move fsparam_string_empty() helper into header since it's currently
open-coded in multiple places
- Add kernel-doc comments to proc_create_net_data_write()
- Don't needlessly read dentry->d_flags twice
Fixes:
- Fix out-of-range warning in nilfs2
- Fix ecryptfs overflow due to wrong encryption packet size
calculation
- Fix overly long line in xfs file_operations (follow-up to FMODE_*
cleanup)
- Don't raise FOP_BUFFER_{R,W}ASYNC for directories in xfs (follow-up
to FMODE_* cleanup)
- Don't call xfs_file_open from xfs_dir_open (follow-up to FMODE_*
cleanup)
- Fix stable offset api to prevent endless loops
- Fix afs file server rotations
- Prevent xattr node from overflowing the eraseblock in jffs2
- Move fdinfo PTRACE_MODE_READ procfs check into the .permission()
operation instead of .open() operation since this caused userspace
regressions"

afs: Fix fileserver rotation getting stuck
Fix the fileserver rotation code in a couple of ways:
(1) op->server_states is an array, not a pointer to a single record, so
fix the places that access it to index it.
(2) In the places that go through an address list to work out which one
has the best priority, fix the loops to skip known failed addresses.
Without this, the rotation algorithm may get stuck on addresses that are
inaccessible or don't respond.
This can be triggered manually by finding a server that advertises a
non-routable address and giving it a higher priority, eg.:
echo "add udp 192.168.0.0/16 3000" >/proc/fs/afs/addr_prefs
if the server, say, includes the address 192.168.7.7 in its address list,
and then attempting to access a volume on that server.

fcntl: add F_DUPFD_QUERY fcntl()
Often userspace needs to know whether two file descriptors refer to the
same struct file. For example, systemd uses this to filter out duplicate
file descriptors in it's file descriptor store (cf. [1]) and vulkan uses
it to compare dma-buf fds (cf. [2]).
The only api we provided for this was kcmp() but that's not generally
available or might be disallowed because it is way more powerful (allows
ordering of file pointers, operates on non-current task) etc. So give
userspace a simple way of comparing two file descriptors for sameness
adding a new fcntl() F_DUDFD_QUERY.

erofs: Zstandard compression support
Add Zstandard compression as the 4th supported algorithm since it becomes more popular now and some end users have asked this for quite a while [1][2]. Each EROFS physical cluster contains only one valid standard Zstandard frame as described in [3] so that decompression can be performed on a per-pcluster basis independently. Currently, it just leverages multi-call stream decompression APIs with internal sliding window buffers. One-shot or bufferless decompression could be implemented later for even better performance if needed.

fs/coredump: Enable dynamic configuration of max file note size
Introduce the capability to dynamically configure the maximum file note size for ELF core dumps via sysctl. Why is this being done? We have observed that during a crash when there are more than 65k mmaps in memory, the existing fixed limit on the size of the ELF notes section becomes a bottleneck. The notes section quickly reaches its capacity, leading to incomplete memory segment information in the resulting coredump. This truncation compromises the utility of the coredumps, as crucial information about the memory state at the time of the crash might be omitted. This enhancement removes the previous static limit of 4MB, allowing system administrators to adjust the size based on system-specific requirements or constraints. Eg: $ sysctl -a | grep core_file_note_size_limit kernel.core_file_note_size_limit = 4194304 $ sysctl -n kernel.core_file_note_size_limit 4194304 $echo 519304 > /proc/sys/kernel/core_file_note_size_limit $sysctl -n kernel.core_file_note_size_limit 519304 Attempting to write beyond the ceiling value of 16MB $echo 17194304 > /proc/sys/kernel/core_file_note_size_limit bash: echo: write error: Invalid argument Signed-off-by: Vijay Nag <nagvijay@microsoft.com> Signed-off-by: Allen Pais <apais@linux.microsoft.com> Link: https://lore.kernel.org/r/20240506193700.7884-1-apais@linux.microsoft.com Signed-off-by: Kees Cook <keescook@chromium.org> |

erofs: add a reserved buffer pool for lz4 decompression
This adds a special global buffer pool (in the end) for reserved pages. Using a reserved pool for LZ4 decompression significantly reduces the time spent on extra temporary page allocation for the extreme cases in low memory scenarios. The table below shows the reduction in time spent on page allocation for LZ4 decompression when using a reserved pool. The results were obtained from multi-app launch benchmarks on ARM64 Android devices running the 5.15 kernel with an 8-core CPU and 8GB of memory. In the benchmark, we launched 16 frequently-used apps, and the camera app was the last one in each round. The data in the table is the average time of camera app for each round. After using the reserved pool, there was an average improvement of 150ms in the overall launch time of our camera app, which was obtained from the systrace log. +--------------+---------------+--------------+---------+ | | w/o page pool | w/ page pool | diff | +--------------+---------------+--------------+---------+ | Average (ms) | 3434 | 21 | -99.38% | +--------------+---------------+--------------+---------+ Based on the benchmark logs, 64 pages are sufficient for 95% of scenarios. This value can be adjusted with a module parameter `reserved_pages`. The default value is 0. This pool is currently only used for the LZ4 decompressor, but it can be applied to more decompressors if needed.

erofs: rename per-CPU buffers to global buffer pool and make it configurable
It will cost more time if compressed buffers are allocated on demand for low-latency algorithms (like lz4) so EROFS uses per-CPU buffers to keep compressed data if in-place decompression is unfulfilled. While it is kind of wasteful of memory for a device with hundreds of CPUs, and only a small number of CPUs concurrently decompress most of the time. This patch renames it as 'global buffer pool' and makes it configurable. This allows two or more CPUs to share a common buffer to reduce memory occupation.
