selftests: netdevsim: Xfail nexthop test on slow machines
A lot of test cases in the file are related to the idle and unbalanced timers of resilient nexthop groups and these tests are reported to be flaky on slow machines running debug kernels. Rather than marking a lot of individual tests with xfail_on_slow(), simply mark all the tests. Note that the test is stable on non-debug machines and that with debug kernels we are mainly interested in the output of various sanitizers in order to determine pass / fail.

selftests: net: packetdrill: xfail all problems on slow machines
We keep seeing flakes on packetdrill on debug kernels, while non-debug kernels are stable, not a single flake in 200 runs. Time to give up, debug kernels appear to suffer from 10msec latency spikes and any timing-sensitive test is bound to flake.

selftests: net: Fix flaky neighbor garbage collection test
The purpose of the "Periodic garbage collection" test case is to make
sure that "extern_valid" neighbors are not flushed during periodic
garbage collection, unlike regular neighbor entries.
The test case is currently doing the following:
1. Changing the base reachable time to 10 seconds so that periodic
garbage collection will run every 5 seconds.
2. Changing the garbage collection stale time to 5 seconds so that
neighbors that have not been used in the last 5 seconds will be
considered for removal.
3. Waiting for the base reachable time change to take effect.
4. Adding an "extern_valid" neighbor, a non-"extern_valid" neighbor and
a bunch of other neighbors so that the threshold ("thresh1") will be
crossed and stale neighbors will be flushed during garbage
collection.
5. Waiting for 10 seconds to give garbage collection a chance to run.
6. Checking that the "extern_valid" neighbor was not flushed and that
the non-"extern_valid" neighbor was flushed.
The test sometimes fails in the netdev CI because the non-"extern_valid"
neighbor was not flushed. I am unable to reproduce this locally, but my
theory that since we do not know exactly when the periodic garbage
collection runs, it is possible for it to run at a time when the
non-"extern_valid" neighbor is still not considered stale.
Fix by moving the addition of the two neighbors before step 3 and by
reducing the garbage collection stale time to 1 second, to ensure that
both neighbors are considered stale when garbage collection runs.

Networking changes for 6.17.
Core & protocols
----------------
- Wrap datapath globals into net_aligned_data, to avoid false sharing.
- Preserve MSG_ZEROCOPY in forwarding (e.g. out of a container).
- Add SO_INQ and SCM_INQ support to AF_UNIX.
- Add SIOCINQ support to AF_VSOCK.
- Add TCP_MAXSEG sockopt to MPTCP.
- Add IPv6 force_forwarding sysctl to enable forwarding per interface.
- Make TCP validation of whether packet fully fits in the receive
window and the rcv_buf more strict. With increased use of HW
aggregation a single "packet" can be multiple 100s of kB.
- Add MSG_MORE flag to optimize large TCP transmissions via sockmap,
improves latency up to 33% for sockmap users.
- Convert TCP send queue handling from tasklet to BH workque.
- Improve BPF iteration over TCP sockets to see each socket exactly once.
- Remove obsolete and unused TCP RFC3517/RFC6675 loss recovery code.
- Support enabling kernel threads for NAPI processing on per-NAPI
instance basis rather than a whole device. Fully stop the kernel NAPI
thread when threaded NAPI gets disabled. Previously thread would stick
around until ifdown due to tricky synchronization.
- Allow multicast routing to take effect on locally-generated packets.
- Add output interface argument for End.X in segment routing.
- MCTP: add support for gateway routing, improve bind() handling.
- Don't require rtnl_lock when fetching an IPv6 neighbor over Netlink.
- Add a new neighbor flag ("extern_valid"), which cedes refresh
responsibilities to userspace. This is needed for EVPN multi-homing
where a neighbor entry for a multi-homed host needs to be synced
across all the VTEPs among which the host is multi-homed.
- Support NUD_PERMANENT for proxy neighbor entries.
- Add a new queuing discipline for IETF RFC9332 DualQ Coupled AQM.
- Add sequence numbers to netconsole messages. Unregister netconsole's
console when all net targets are removed. Code refactoring.
Add a number of selftests.
- Align IPSec inbound SA lookup to RFC 4301. Only SPI and protocol
should be used for an inbound SA lookup.
- Support inspecting ref_tracker state via DebugFS.
- Don't force bonding advertisement frames tx to ~333 ms boundaries.
Add broadcast_neighbor option to send ARP/ND on all bonded links.
- Allow providing upcall pid for the 'execute' command in openvswitch.
- Remove DCCP support from Netfilter's conntrack.
- Disallow multiple packet duplications in the queuing layer.
- Prevent use of deprecated iptables code on PREEMPT_RT.
Driver API
----------

Summary
* Move sysctls out of the kern_table array
This is the final move of ctl_tables into their respective subsystems. Only 5
(out of the original 50) will remain in kernel/sysctl.c file; these handle
either sysctl or common arch variables.
By decentralizing sysctl registrations, subsystem maintainers regain control
over their sysctl interfaces, improving maintainability and reducing the
likelihood of merge conflicts.
* docs: Remove false positives from check-sysctl-docs
Stopped falsely identifying sysctls as undocumented or unimplemented in the
check-sysctl-docs script. This script can now be used to automatically
identify if documentation is missing.
* Testing
All these have been in linux-next since rc3, giving them a solid 3 to 4 weeks
worth of testing. Additionally, sysctl selftests and kunit were also run
locally on my x86_64

Merge tag 'sysctl-6.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/sysctl/sysctl
Pull sysctl updates from Joel Granados:
- Move sysctls out of the kern_table array
This is the final move of ctl_tables into their respective
subsystems. Only 5 (out of the original 50) will remain in
kernel/sysctl.c file; these handle either sysctl or common arch
variables.
By decentralizing sysctl registrations, subsystem maintainers regain
control over their sysctl interfaces, improving maintainability and
reducing the likelihood of merge conflicts.
- docs: Remove false positives from check-sysctl-docs
Stopped falsely identifying sysctls as undocumented or unimplemented
in the check-sysctl-docs script. This script can now be used to
automatically identify if documentation is missing.

Pull arm64 updates from Catalin Marinas:
"A quick summary: perf support for Branch Record Buffer Extensions
(BRBE), typical PMU hardware updates, small additions to MTE for
store-only tag checking and exposing non-address bits to signal

Updates for the generic entry code:
- Split the code into syscall and exception/interrupt parts to ease the
conversion of ARM[64] to the generic entry infrastructure
- Extend syscall user dispatching to support a single intercepted range
instead of the default single non-intercepted range. That allows
monitoring/analysis of a specific executable range, e.g. a library, and
also provides flexibility for sandboxing scenarios.
- Cleanup and extend the user dispatch selftest

Crypto library updates for 6.17
This is the main crypto library pull request for 6.17. The main focus
this cycle is on reorganizing the SHA-1 and SHA-2 code, providing
high-quality library APIs for SHA-1 and SHA-2 including HMAC support,
and establishing conventions for lib/crypto/ going forward:
- Migrate the SHA-1 and SHA-512 code (and also SHA-384 which shares
most of the SHA-512 code) into lib/crypto/. This includes both the
generic and architecture-optimized code. Greatly simplify how the
architecture-optimized code is integrated. Add an easy-to-use
library API for each SHA variant, including HMAC support. Finally,
reimplement the crypto_shash support on top of the library API.
- Apply the same reorganization to the SHA-256 code (and also SHA-224
which shares most of the SHA-256 code). This is a somewhat smaller
change, due to my earlier work on SHA-256. But this brings in all
the same additional improvements that I made for SHA-1 and SHA-512.
There are also some smaller changes:
- Move the architecture-optimized ChaCha, Poly1305, and BLAKE2s code
from arch/$(SRCARCH)/lib/crypto/ to lib/crypto/$(SRCARCH)/. For
these algorithms it's just a move, not a full reorganization yet.
- Fix the MIPS chacha-core.S to build with the clang assembler.
- Fix the Poly1305 functions to work in all contexts.
- Fix a performance regression in the x86_64 Poly1305 code.
- Clean up the x86_64 SHA-NI optimized SHA-1 assembly code.
Note that since the new organization of the SHA code is much simpler,
the diffstat of this pull request is negative, despite the addition of
new fully-documented library APIs for multiple SHA and HMAC-SHA
variants. These APIs will allow further simplifications across the
kernel as users start using them instead of the old-school crypto API.
(I've already written a lot of such conversion patches, removing over
1000 more lines of code. But most of those will target 6.18 or later.)

Pull pidfs updates from Christian Brauner:
- persistent info
Persist exit and coredump information independent of whether anyone
currently holds a pidfd for the struct pid.
The current scheme allocated pidfs dentries on-demand repeatedly.
This scheme is reaching it's limits as it makes it impossible to pin
information that needs to be available after the task has exited or
coredumped and that should not be lost simply because the pidfd got
closed temporarily. The next opener should still see the stashed
information.
This is also a prerequisite for supporting extended attributes on
pidfds to allow attaching meta information to them.
If someone opens a pidfd for a struct pid a pidfs dentry is allocated
and stashed in pid->stashed. Once the last pidfd for the struct pid
is closed the pidfs dentry is released and removed from pid->stashed.
So if 10 callers create a pidfs dentry for the same struct pid
sequentially, i.e., each closing the pidfd before the other creates a
new one then a new pidfs dentry is allocated every time.
Because multiple tasks acquiring and releasing a pidfd for the same
struct pid can race with each another a task may still find a valid
pidfs entry from the previous task in pid->stashed and reuse it. Or
it might find a dead dentry in there and fail to reuse it and so
stashes a new pidfs dentry. Multiple tasks may race to stash a new
pidfs dentry but only one will succeed, the other ones will put their
dentry.
The current scheme aims to ensure that a pidfs dentry for a struct
pid can only be created if the task is still alive or if a pidfs
dentry already existed before the task was reaped and so exit
information has been was stashed in the pidfs inode.
That's great except that it's buggy. If a pidfs dentry is stashed in
pid->stashed after pidfs_exit() but before __unhash_process() is
called we will return a pidfd for a reaped task without exit
information being available.
The pidfds_pid_valid() check does not guard against this race as it
doens't sync at all with pidfs_exit(). The pid_has_task() check might
be successful simply because we're before __unhash_process() but
after pidfs_exit().
Introduce a new scheme where the lifetime of information associated
with a pidfs entry (coredump and exit information) isn't bound to the
lifetime of the pidfs inode but the struct pid itself.
The first time a pidfs dentry is allocated for a struct pid a struct
pidfs_attr will be allocated which will be used to store exit and
coredump information.
If all pidfs for the pidfs dentry are closed the dentry and inode can
be cleaned up but the struct pidfs_attr will stick until the struct
pid itself is freed. This will ensure minimal memory usage while
persisting relevant information.
The new scheme has various advantages. First, it allows to close the
race where we end up handing out a pidfd for a reaped task for which
no exit information is available. Second, it minimizes memory usage.
Third, it allows to remove complex lifetime tracking via dentries
when registering a struct pid with pidfs. There's no need to get or
put a reference. Instead, the lifetime of exit and coredump
information associated with a struct pid is bound to the lifetime of
struct pid itself.
- extended attributes
Now that we have a way to persist information for pidfs dentries we
can start supporting extended attributes on pidfds. This will allow
userspace to attach meta information to tasks.
One natural extension would be to introduce a custom pidfs.* extended
attribute space and allow for the inheritance of extended attributes
across fork() and exec().
The first simple scheme will allow privileged userspace to set
trusted extended attributes on pidfs inodes.
- Allow autonomous pidfs file handles
Various filesystems such as pidfs and drm support opening file
handles without having to require a file descriptor to identify the
filesystem. The filesystem are global single instances and can be
trivially identified solely on the information encoded in the file
handle.
This makes it possible to not have to keep or acquire a sentinal file
descriptor just to pass it to open_by_handle_at() to identify the
filesystem. That's especially useful when such sentinel file
descriptor cannot or should not be acquired.
For pidfs this means a file handle can function as full replacement
for storing a pid in a file. Instead a file handle can be stored and
reopened purely based on the file handle.
Such autonomous file handles can be opened with or without specifying
a a file descriptor. If no proper file descriptor is used the
FD_PIDFS_ROOT sentinel must be passed. This allows us to define
further special negative fd sentinels in the future.
Userspace can trivially test for support by trying to open the file
handle with an invalid file descriptor.
- Allow pidfds for reaped tasks with SCM_PIDFD messages
This is a logical continuation of the earlier work to create pidfds
for reaped tasks through the SO_PEERPIDFD socket option merged in

Pull coredump updates from Christian Brauner:
"This contains an extension to the coredump socket and a proper rework
of the coredump code.
- This extends the coredump socket to allow the coredump server to
tell the kernel how to process individual coredumps. This allows
for fine-grained coredump management. Userspace can decide to just
let the kernel write out the coredump, or generate the coredump
itself, or just reject it.
* COREDUMP_KERNEL
The kernel will write the coredump data to the socket.
* COREDUMP_USERSPACE
The kernel will not write coredump data but will indicate to the
parent that a coredump has been generated. This is used when
userspace generates its own coredumps.
* COREDUMP_REJECT
The kernel will skip generating a coredump for this task.
* COREDUMP_WAIT
The kernel will prevent the task from exiting until the coredump
server has shutdown the socket connection.
The flexible coredump socket can be enabled by using the "@@"
prefix instead of the single "@" prefix for the regular coredump
socket:
@@/run/systemd/coredump.socket
- Cleanup the coredump code properly while we have to touch it
anyway.
Split out each coredump mode in a separate helper so it's easy to
grasp what is going on and make the code easier to follow. The core
coredump function should now be very trivial to follow"

selftests/bpf: Test invariants on JSLT crossing sign
The improvement of the u64/s64 range refinement fixed the invariant violation that was happening on this test for BPF_JSLT when crossing the sign boundary. After this patch, we have one test remaining with a known invariant violation. It's the same test as fixed here but for 32 bits ranges.

selftests/bpf: Test cross-sign 64bits range refinement
This patch adds coverage for the new cross-sign 64bits range refinement
logic. The three tests cover the cases when the u64 and s64 ranges
overlap (1) in the negative portion of s64, (2) in the positive portion
of s64, and (3) in both portions.
The first test is a simplified version of a BPF program generated by
syzkaller that caused an invariant violation [1]. It looks like
syzkaller could not extract the reproducer itself (and therefore didn't
report it to the mailing list), but I was able to extract it from the
console logs of a crash.
The principle is similar to the invariant violation described in
commit

selftests/bpf: Increase xdp data size for arm64 64K page size
With arm64 64K page size, the following 4 subtests failed:
#97/25 dynptr/test_probe_read_user_dynptr:FAIL
#97/26 dynptr/test_probe_read_kernel_dynptr:FAIL
#97/27 dynptr/test_probe_read_user_str_dynptr:FAIL
#97/28 dynptr/test_probe_read_kernel_str_dynptr:FAIL
These failures are due to function bpf_dynptr_check_off_len() in
include/linux/bpf.h where there is a test
if (len > size || offset > size - len)
return -E2BIG;
With 64K page size, the 'offset' is greater than 'size - len',
which caused the test failure.
For 64KB page size, this patch increased the xdp buffer size from 5000 to
90000. The above 4 test failures are fixed as 'size' value is increased.
But it introduced two new failures:
#97/4 dynptr/test_dynptr_copy_xdp:FAIL
#97/12 dynptr/test_dynptr_memset_xdp_chunks:FAIL
These two failures will be addressed in subsequent patches.

selftests: drv-net: Wait for bkg socat to start
Currently, UDP exchange is prone to failure when cmd attempt to send data while socat in bkg is not ready. Since, the behavior is probabilistic, this can result in flakiness for XDP tests. While testing test_xdp_native_tx_mb() on netdevsim, a failure rate of around 1% in 500 500 iterations was observed. Use wait_port_listen() to ensure that the bkg socat is started and ready to receive before cmd start sending. With proposed changes, a re-run of the same test passed 100% of time.

ipv6: add force_forwarding sysctl to enable per-interface forwarding
It is currently impossible to enable ipv6 forwarding on a per-interface basis like in ipv4. To enable forwarding on an ipv6 interface we need to enable it on all interfaces and disable it on the other interfaces using a netfilter rule. This is especially cumbersome if you have lots of interfaces and only want to enable forwarding on a few. According to the sysctl docs [0] the `net.ipv6.conf.all.forwarding` enables forwarding for all interfaces, while the interface-specific `net.ipv6.conf.<interface>.forwarding` configures the interface Host/Router configuration. Introduce a new sysctl flag `force_forwarding`, which can be set on every interface. The ip6_forwarding function will then check if the global forwarding flag OR the force_forwarding flag is active and forward the packet. To preserve backwards-compatibility reset the flag (on all interfaces) to 0 if the net.ipv6.conf.all.forwarding flag is set to 0. Add a short selftest that checks if a packet gets forwarded with and without `force_forwarding`.

selftests: net: Skip test if IPv6 is not configured
Extend the `check_for_dependencies()` function in `lib_netcons.sh` to check whether IPv6 is enabled by verifying the existence of `/proc/net/if_inet6`. Having IPv6 is a now a dependency of netconsole tests. If the file does not exist, the script will skip the test with an appropriate message suggesting to verify if `CONFIG_IPV6` is enabled. This prevents the test to misbehave if IPv6 is not configured.

selftests: drv-net: tso: fix non-tunneled tso6 test case name
The non-tunneled tso6 test case was showing up as:
ok 8 tso.ipv4
This is because of the way test_builder() uses the inner_ipver arg in
test naming, and how test_info is iterated over in main(). Given that
some tunnels not supported yet, e.g. ipip or sit, only support ipv4 or
ipv6 as the inner network protocol, I think the best fix here is to
call test_builder() in separate branches for tunneled and non-tunneled
tests, and to make supported inner l3 types an explicit attribute of
tunnel test cases.

SKB_GSO_UDP_TUNNEL_CSUM.

tso.py uses the active features at the time of test execution
as the set of available gso features to test. This means if a gso
feature is supported but toggled off at test start, the test will be
skipped with a "Device does not support {feature}" message.
Instead, we can enumerate the set of toggleable features by capturing
the driver's hw_features bitmap. To avoid configuration side-effects
from running the test, we also snapshot the wanted_features flag set
before making any feature changes, and then attempt to restore the
same set of wanted_features before test exit.

Make require_cmd() calls explicit about whether commands are needed locally, remotely, or both. Since require_cmd() defaults to local=True, tests should explicitly set local=False when commands are only needed remotely. - socat: Set local=False since it's only needed on remote hosts. - iperf3: Use single call with both local=True and remote=True since it's needed on both hosts. This avoids unnecessary test failures when commands are missing locally but available remotely where actually needed, and consolidates a duplicate require_cmd() call into single call that checks both hosts.
