Until we are certain that existing classful qdiscs work with bpf qdisc,
make sure we don't allow attaching a bpf qdisc to non root. Meanwhile,
attaching to mq is allowed.

The ovpn-cli tool can be compiled and used as selftest for the ovpn
kernel module.
[NOTE: it depends on libmedtls for decoding base64-encoded keys]
ovpn-cli implements the netlink and RTNL APIs and can thus be integrated
in any script for more automated testing.
Along with the tool, a bunch of scripts are provided that perform basic
functionality tests by means of network namespaces.
These scripts take part to the kselftest automation.
The output of the scripts, which will appear in the kselftest
reports, is a list of steps performed by the scripts plus some
output coming from the execution of `ping`, `iperf` and `ovpn-cli`
itself.
In general it is useful only in case of failure, in order to
understand which step has failed and why.
Please note: since peer sockets are tied to the userspace
process that created them (i.e. exiting the process will result
in closing the socket), every run of ovpn-cli that created
one will go to background and enter pause(), waiting for the
signal which will allow it to terminate.
Termination is accomplished at the end of each script by
issuing a killall command.

bash and dash evaluate variables differently.
dash will evaluate '\\' every time it is read whereas bash does not.
TEST_STRING="$TEST_STRING \\$i"
echo $TEST_STRING
With i=123
On bash, that will print "\123"
but on dash, that will print the escape sequence of \123 as the \ will be
interpreted again in the echo.
The dynevent_limitations.tc test created a very large list of arguments to
test the maximum number of arguments to pass to the dynamic events file.
It had a loop of:
TEST_STRING=$1
# Acceptable
for i in `seq 1 $MAX_ARGS`; do
TEST_STRING="$TEST_STRING \\$i"
done
echo "$TEST_STRING" >> dynamic_events
This worked fine on bash, but when run on dash it failed.
This was due to dash interpreting the "\\$i" twice. Once when it was
assigned to TEST_STRING and a second time with the echo $TEST_STRING.
bash does not process the backslash more than the first time.
To solve this, assign a double backslash to a variable "bs" and then echo
it to "ts". If "ts" changes, it is dash, if not, it is bash. Then update
"bs" accordingly, and use that to assign TEST_STRING.
Now this could possibly just check if "$BASH" is defined or not, but this
is testing if the issue exists and not just which shell is being used.

Enabling a (modular) test should not silently enable additional kernel
functionality, as that may increase the attack vector of a product.
Fix this by making PRIME_NUMBERS_KUNIT_TEST depend on PRIME_NUMBERS
instead of selecting it.
After this, one can safely enable CONFIG_KUNIT_ALL_TESTS=m to build
modules for all appropriate tests for ones system, without pulling in
extra unwanted functionality, while still allowing a tester to manually
enable PRIME_NUMBERS and this test suite on a system where PRIME_NUMBERS
is not enabled by default. Resurrect CONFIG_PRIME_NUMBERS=m in
tools/testing/selftests/lib/config for the latter use case.

there is a lack of ai_protocol(IPPROTO_MPTCP) usage. Add comment for

This patch first uses IPPROTO_MPTCP to get addrinfo, and if glibc

The parent commit adds this new counter, incremented when receiving a
connection request, if the PM didn't allow the creation of new subflows.
Most of the time, it is then kept at 0, except when the PM limits cause
the receiver side to reject new MPJoin connections. This is the case in
the following tests:
- single subflow, limited by server
- multiple subflows, limited by server
- subflows limited by server w cookies
- userspace pm type rejects join
- userspace pm type prevents mp_prio
Simply set join_syn_rej=1 when checking the MPJoin counters for these
tests.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing fixes from Steven Rostedt:
- Hide get_vm_area() from MMUless builds
The function get_vm_area() is not defined when CONFIG_MMU is not
defined. Hide that function within #ifdef CONFIG_MMU.
- Fix output of synthetic events when they have dynamic strings
The print fmt of the synthetic event's format file use to have "%.*s"
for dynamic size strings even though the user space exported
arguments had only __get_str() macro that provided just a nul
terminated string. This was fixed so that user space could parse this
properly.
But the reason that it had "%.*s" was because internally it provided
the maximum size of the string as one of the arguments. The fix that
replaced "%.*s" with "%s" caused the trace output (when the kernel
reads the event) to write "(efault)" as it would now read the length
of the string as "%s".
As the string provided is always nul terminated, there's no reason
for the internal code to use "%.*s" anyway. Just remove the length
argument to match the "%s" that is now in the format.
- Fix the ftrace subops hash logic of the manager ops hash
The function_graph uses the ftrace subops code. The subops code is a
way to have a single ftrace_ops registered with ftrace to determine
what functions will call the ftrace_ops callback. More than one user
of function graph can register a ftrace_ops with it. The function
graph infrastructure will then add this ftrace_ops as a subops with
the main ftrace_ops it registers with ftrace. This is because the
functions will always call the function graph callback which in turn
calls the subops ftrace_ops callbacks.
The main ftrace_ops must add a callback to all the functions that the
subops want a callback from. When a subops is registered, it will
update the main ftrace_ops hash to include the functions it wants.
This is the logic that was broken.
The ftrace_ops hash has a "filter_hash" and a "notrace_hash" where
all the functions in the filter_hash but not in the notrace_hash are
attached by ftrace. The original logic would have the main ftrace_ops
filter_hash be a union of all the subops filter_hashes and the main
notrace_hash would be a intersect of all the subops filter hashes.
But this was incorrect because the notrace hash depends on the
filter_hash it is associated to and not the union of all
filter_hashes.
Instead, when a subops is added, just include all the functions of
the subops hash that are in its filter_hash but not in its
notrace_hash. The main subops hash should not use its notrace hash,
unless all of its subops hashes have an empty filter_hash (which
means to attach to all functions), and then, and only then, the main
ftrace_ops notrace hash can be the intersect of all the subops
hashes.
This not only fixes the bug, but also simplifies the code.
- Add a selftest to better test the subops filtering
Add a selftest that would catch the bug fixed by the above change.
- Fix extra newline printed in function tracing with retval
The function parameter code changed the output logic slightly and
called print_graph_retval() and also printed a newline. The
print_graph_retval() also prints a newline which caused blank lines
to be printed in the function graph tracer when retval was added.
This caused one of the selftests to fail if retvals were enabled.
Instead remove the new line output from print_graph_retval() and have
the callers always print the new line so that it doesn't have to do
special logic if it calls print_graph_retval() or not.
- Fix out-of-bound memory access in the runtime verifier
When rv_is_container_monitor() is called on the last entry on the
link list it references the next entry, which is the list head and
causes an out-of-bound memory access.

- Make res_spin_lock test less verbose, since it was spamming BPF
CI on failure, and make the check for AA deadlock stronger
- Fix rebasing mistake and use architecture provided
res_smp_cond_load_acquire
- Convert BPF maps (queue_stack and ringbuf) to resilient spinlock
to address long standing syzbot reports
- Make sure that classic BPF load instruction from SKF_[NET|LL]_OFF
offsets works when skb is fragmeneted (Willem de Bruijn)

When running mincore test cases, I encountered the following failures:
"
mincore_selftest.c:359:check_tmpfs_mmap:Expected ra_pages (511) == 0 (0)
mincore_selftest.c:360:check_tmpfs_mmap:Read-ahead pages found in memory
check_tmpfs_mmap: Test terminated by assertion
FAIL global.check_tmpfs_mmap
not ok 5 global.check_tmpfs_mmap
FAILED: 4 / 5 tests passed
"
The reason for the test case failure is that my system automatically enabled
tmpfs large folio allocation by adding the 'transparent_hugepage_tmpfs=always'
cmdline. However, the test case still expects the tmpfs mounted on /dev/shm to
allocate small folios, which leads to assertion failures when verifying readahead
pages.
As discussed with David, there's no reason to continue checking the readahead
logic for tmpfs. Drop it to fix this issue.

Currently if the filesystem for the cgroups version it wants to use is not
mounted charge_reserved_hugetlb.sh and hugetlb_reparenting_test.sh tests
will attempt to mount it on the hard coded path /dev/cgroup/memory,
deleting that directory when the test finishes. This will fail if there
is not a preexisting directory at that path, and since the directory is
deleted subsequent runs of the test will fail. Instead of relying on this
hard coded directory name use mktemp to generate a temporary directory to
use as a mountpoint, fixing both the assumption and the disruption caused
by deleting a preexisting directory.
This means that if the relevant cgroup filesystem is not already mounted
then we rely on having coreutils (which provides mktemp) installed. I
suspect that many current users are relying on having things automounted
by default, and given that the script relies on bash it's probably not an
unreasonable requirement.

A bug was discovered that showed the accounting of the subops of the
ftrace_ops filtering was incorrect. Add a new test to better test the
filtering.
This test creates two instances, where it will add various filters to both
the set_ftrace_filter and the set_ftrace_notrace files and enable
function_graph. Then it looks into the enabled_functions file to make sure
that the filters are behaving correctly.

The torture.sh --do-rt command-line parameter is intended to mimic -rt
kernels. Now that CONFIG_PREEMPT_RT is upstream, this commit makes this
mimicking more precise.
Note that testing of RCU priority boosting is disabled in favor
of forward-progress testing of RCU callbacks. If it turns out to be
possible to make kernels built with CONFIG_PREEMPT_RT=y to tolerate
testing of both, both will be enabled.

Add audit.thread tests to check that the PID tied to a domain is not a
thread ID but the thread group ID. These new tests would not pass
without the previous TGID fix.
Extend matches_log_domain_allocated() to check against the PID that
created the domain.

The rtnetlink family names are set to rt-$name within the YAML
but the files are called rt_$name. C codegen assumes that the
generated file name will match the family. The use of dashes
is in line with our general expectation that name properties
in the spec use dashes not underscores (even tho, as Donald
points out most genl families use underscores in the name).
We have 3 un-ideal options to choose from:
- accept the slight inconsistency with old families using _, or
- accept the slight annoyance with all languages having to do s/-/_/
when looking up family ID, or
- accept the inconsistency with all name properties in new YAML spec
being separated with - and just the family name always using _.
Pick option 1 and rename the rtnl spec files.
