kselftest/arm64: Add a test case for SVE VL changes with SME active
We just fixed an issue where changing the SVE VL while SME was active could result in us attempting to save the streaming mode SVE vectors without any backing storage. Add a test case which provokes that issue, ideally we should also verify that the contents of ZA are unaffected by any of what we did. Note that since we need to keep streaming mode enabled we can't use any syscalls to trigger the issue, we have to sit in a loop in usersapce and hope to be preempted. The chosen numbers trigger with defconfig on all the virtual platforms for me, this won't be 100% on all systems but avoid an overcomplicated test implementation.

sound fixes for 6.5-rc3
A pile of fixes that have been gathered since the previous PR.
Most of changes are device-specific, and nothing looks too scary.
- A memory leak fix in ALSA sequencer code in 6.5-rc
- Many fixes for ASoC Qualcomm CODEC drivers, covering SoundWire probe
problems
- A series of ASoC AMD fixes
- A few fixes and cleanups of selftest stuff
- HD-audio codec fixes and quirks for Clevo, HP, Lenovo, Dell

When looking at the TC selftest reports, I noticed one test was failing

Could not match regex pattern. Verify command output:
cat: /proc/net/nf_conntrack: No such file or directory
It is only available if NF_CONNTRACK_PROCFS kconfig is set. So the issue
can be fixed simply by adding it to the list of required kconfig.

selftests: tc: add 'ct' action kconfig dep
When looking for something else in LKFT reports [1], I noticed most of
the tests were skipped because the "teardown stage" did not complete
successfully.
Pedro found out this is due to the fact CONFIG_NF_FLOW_TABLE is required
but not listed in the 'config' file. Adding it to the list fixes the
issues on LKFT side. CONFIG_NET_ACT_CT is now set to 'm' in the final
kconfig.

selftests: tc: set timeout to 15 minutes
When looking for something else in LKFT reports [1], I noticed that the
TC selftest ended with a timeout error:
not ok 1 selftests: tc-testing: tdc.sh # TIMEOUT 45 seconds
The timeout had been introduced 3 years ago, see the Fixes commit below.
This timeout is only in place when executing the selftests via the
kselftests runner scripts. I guess this is not what most TC devs are
using and nobody noticed the issue before.
The new timeout is set to 15 minutes as suggested by Pedro [2]. It looks
like it is plenty more time than what it takes in "normal" conditions.

selftests/arm64: fix build failure during the "emit_tests" step
The build failure reported in [1] occurred because commit <9fc96c7c19df>
("selftests: error out if kernel header files are not yet built") added
a new "kernel_header_files" dependency to "all", and that triggered
another, pre-existing problem. Specifically, the arm64 selftests
override the emit_tests target, and that override improperly declares
itself to depend upon the "all" target.
This is a problem because the "emit_tests" target in lib.mk was not
intended to be overridden. emit_tests is a very simple, sequential build
target that was originally invoked from the "install" target, which in
turn, depends upon "all".
That approach worked for years. But with

Tracing fixes and clean ups:
- Fix some missing-prototype warnings - Fix user events struct args (did not include size of struct) When creating a user event, the "struct" keyword is to denote that the size of the field will be passed in. But the parsing failed to handle this case. - Add selftest to struct sizes for user events - Fix sample code for direct trampolines. The sample code for direct trampolines attached to handle_mm_fault(). But the prototype changed and the direct trampoline sample code was not updated. Direct trampolines needs to have the arguments correct otherwise it can fail or crash the system. - Remove unused ftrace_regs_caller_ret() prototype. - Quiet false positive of FORTIFY_SOURCE Due to backward compatibility, the structure used to save stack traces in the kernel had a fixed size of 8. This structure is exported to user space via the tracing format file. A change was made to allow more than 8 functions to be recorded, and user space now uses the size field to know how many functions are actually in the stack. But the structure still has size of 8 (even though it points into the ring buffer that has the required amount allocated to hold a full stack. This was fine until the fortifier noticed that the memcpy(&entry->caller, stack, size) was greater than the 8 functions and would complain at runtime about it. Hide this by using a pointer to the stack location on the ring buffer instead of using the address of the entry structure caller field. - Fix a deadloop in reading trace_pipe that was caused by a mismatch between ring_buffer_empty() returning false which then asked to read the data, but the read code uses rb_num_of_entries() that returned zero, and causing a infinite "retry". - Fix a warning caused by not using all pages allocated to store ftrace functions, where this can happen if the linker inserts a bunch of "NULL" entries, causing the accounting of how many pages needed to be off. - Fix histogram synthetic event crashing when the start event is removed and the end event is still using a variable from it. - Fix memory leak in freeing iter->temp in tracing_release_pipe() -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZLBF6hQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qkswAP4mhdoFFfNosM7+Sh/R4t31IxKZApm9 M2Hf9jgvJ7b65AD/VV1XfO6skw2+5Yn9S4UyNE2MQaYxPwWpONcNFUzZ3Q8= =Nb+7 -----END PGP SIGNATURE----- Merge tag 'trace-v6.5-rc1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Fix some missing-prototype warnings - Fix user events struct args (did not include size of struct) When creating a user event, the "struct" keyword is to denote that the size of the field will be passed in.

Use the bpf_timer_set_callback helper to mark timer_cb as an async callback, and put a direct call to timer_cb in the main subprog.

selftests: mptcp: pm_nl_ctl: fix 32-bit support
When using pm_nl_ctl to validate userspace path-manager's behaviours, it was failing on 32-bit architectures ~half of the time. pm_nl_ctl was not reporting any error but the command was not doing what it was expected to do. As a result, the expected linked event was not triggered after and the test failed. This is due to the fact the token given in argument to the application was parsed as an integer with atoi(): in a 32-bit arch, if the number was bigger than INT_MAX, 2147483647 was used instead. This can simply be fixed by using strtoul() instead of atoi(). The errors have been seen "by chance" when manually looking at the results from LKFT. Fixes: |

selftests: mptcp: depend on SYN_COOKIES
MPTCP selftests are using TCP SYN Cookies for quite a while now, since
v5.9.
Some CIs don't have this config option enabled and this is causing
issues in the tests:
# ns1 MPTCP -> ns1 (10.0.1.1:10000 ) MPTCP (duration 167ms) sysctl: cannot stat /proc/sys/net/ipv4/tcp_syncookies: No such file or directory
# [ OK ]./mptcp_connect.sh: line 554: [: -eq: unary operator expected
There is no impact in the results but the test is not doing what it is
supposed to do.

wireguard: netlink: send staged packets when setting initial private key
Packets bound for peers can queue up prior to the device private key
being set. For example, if persistent keepalive is set, a packet is
queued up to be sent as soon as the device comes up. However, if the
private key hasn't been set yet, the handshake message never sends, and
no timer is armed to retry, since that would be pointless.
But, if a user later sets a private key, the expectation is that those
queued packets, such as a persistent keepalive, are actually sent. So
adjust the configuration logic to account for this edge case, and add a
test case to make sure this works.
Maxim noticed this with a wg-quick(8) config to the tune of:
[Interface]
PostUp = wg set %i private-key somefile
[Peer]
PublicKey = ...
Endpoint = ...
PersistentKeepalive = 25
Here, the private key gets set after the device comes up using a PostUp
script, triggering the bug.

Merge tag 'cxl-for-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl
Pull CXL updates from Dan Williams:
"The highlights in terms of new functionality are support for the
standard CXL Performance Monitor definition that appeared in CXL 3.0,
support for device sanitization (wiping all data from a device),
secure-erase (re-keying encryption of user data), and support for
firmware update. The firmware update support is notable as it reuses
the simple sysfs_upload interface to just cat(1) a blob to a sysfs
file and pipe that to the device.
Additionally there are a substantial number of cleanups and
reorganizations to get ready for RCH error handling (RCH == Restricted
CXL Host == current shipping hardware generation / pre CXL-2.0
topologies) and type-2 (accelerator / vendor specific) devices.
For vendor specific devices they implement a subset of what the
generic type-3 (generic memory expander) driver expects. As a result
the rework decouples optional infrastructure from the core driver
context.
For RCH topologies, where the specification working group did not want
to confuse pre-CXL-aware operating systems, many of the standard
registers are hidden which makes support standard bus features like
AER (PCIe Advanced Error Reporting) difficult. The rework arranges for
the driver to help the PCI-AER core. Bjorn is on board with this
direction but a late regression disocvery means the completion of this
functionality needs to cook a bit longer, so it is code
reorganizations only for now.
Summary:
- Add infrastructure for supporting background commands along with
support for device sanitization and firmware update

Probes updates for v6.5:
- fprobe: Pass return address to the fprobe entry/exit callbacks so that
the callbacks don't need to analyze pt_regs/stack to find the function
return address.
- kprobe events: cleanup usage of TPARG_FL_FENTRY and TPARG_FL_RETURN
flags so that those are not set at once.
- fprobe events:
. Add a new fprobe events for tracing arbitrary function entry and
exit as a trace event.
. Add a new tracepoint events for tracing raw tracepoint as a trace
event. This allows user to trace non user-exposed tracepoints.
. Move eprobe's event parser code into probe event common file.
. Introduce BTF (BPF type format) support to kernel probe (kprobe,
fprobe and tracepoint probe) events so that user can specify traced
function arguments by name. This also applies the type of argument
when fetching the argument.
. Introduce '$arg*' wildcard support if BTF is available. This expands
the '$arg*' meta argument to all function argument automatically.
. Check the return value types by BTF. If the function returns 'void',
'$retval' is rejected.
. Add some selftest script for fprobe events, tracepoint events and
BTF support.
. Update documentation about the fprobe events.
. Some fixes for above features, document and selftests.
- selftests for ftrace (except for new fprobe events):
. Add a test case for multiple consecutive probes in a function which
checks if ftrace based kprobe, optimized kprobe and normal kprobe
can be defined in the same target function.
. Add a test case for optimized probe, which checks whether kprobe
can be optimized or not.
