Some drivers, like tg3, do not set combined-count:
$ ethtool -l enp4s0f1
Channel parameters for enp4s0f1:
Pre-set maximums:
RX: 4
TX: 4
Other: n/a
Combined: n/a
Current hardware settings:
RX: 4
TX: 1
Other: n/a
Combined: n/a
In the case where combined-count is not set, the ethtool netlink code
in the kernel elides the value and the code in the test:
netnl.channels_get(...)
With a tg3 device, the returned dictionary looks like:
{'header': {'dev-index': 3, 'dev-name': 'enp4s0f1'},
'rx-max': 4,
'rx-count': 4,
'tx-max': 4,
'tx-count': 1}
Note that the key 'combined-count' is missing. As a result of this
missing key the test raises an exception:
# Exception| if channels['combined-count'] == 0:
# Exception| ~~~~~~~~^^^^^^^^^^^^^^^^^^
# Exception| KeyError: 'combined-count'
Change the test to check if 'combined-count' is a key in the dictionary
first and if not assume that this means the driver has separate RX and
TX queues.
With this change, the test now passes successfully on tg3 and mlx5
(which does have a 'combined-count').

- A fix for the rseq selftests, which was using an invalid constraint.
- A pair of fixes for signal frame size handling:
- We were reserving space for an extra empty extension context
header on systems with extended signal context, thus resulting in
unnecessarily large allocations.
- We weren't properly checking for available extensions before
calculating the signal stack size, which resulted in undersized
stack allocations on some systems (at least those with T-Head
custom vectors).

Pull tracing fixes from Steven Rostedt:
"Function graph accounting fixes:
- Fix the manage ops hashes
The function graph registers a "manager ops" and "sub-ops" to
ftrace. The manager ops does not have any callback but calls the
sub-ops callbacks. The manage ops hashes (what is used to tell
ftrace what functions to attach to) is built on the sub-ops it
manages.
There was an error in the way it built the hash. An empty hash
means to attach to all functions. When the manager ops had one
sub-ops it properly copied its hash. But when the manager ops had
more than one sub-ops, it went into a loop to make a set of all
functions it needed to add to the hash. If any of the subops hashes
was empty, that would mean to attach to all functions. The error
was that the first iteration of the loop passed in an empty hash to
start with in order to add the other hashes. That starting hash was
mistaken as to attach to all functions. This made the manage ops
attach to all functions whenever it had two or more sub-ops, even
if each sub-op was attached to only a single function.
- Do not add duplicate entries to the manager ops hash
If two or more subops hashes trace the same function, an entry for
that function will be added to the manager ops for each subops.
This causes waste and extra overhead.
Fprobe accounting fixes:
- Remove last function from fprobe hash
Fprobes has a ftrace hash to manage which functions an fprobe is
attached to. It also has a counter of how many fprobes are
attached. When the last fprobe is removed, it unregisters the
fprobe from ftrace but does not remove the functions the last
fprobe was attached to from the hash. This leaves the old functions
attached. When a new fprobe is added, the fprobe infrastructure
attaches to not only the functions of the new fprobe, but also to
the functions of the last fprobe.
- Fix accounting of the fprobe counter
When a fprobe is added, it updates a counter. If the counter goes
from zero to one, it attaches its ops to ftrace. When an fprobe is
removed, the counter is decremented. If the counter goes from 1 to
zero, it removes the fprobes ops from ftrace.
There was an issue where if two fprobes trace the same function,
the addition of each fprobe would increment the counter. But when
removing the first of the fprobes, it would notice that another
fprobe is still attached to one of its functions no it does not
remove the functions from the ftrace ops.
But it also did not decrement the counter, so when the last fprobe
is removed, the counter is still one. This leaves the fprobes
callback still registered with ftrace and it being called by the
functions defined by the fprobes ops hash. Worse yet, because all
the functions from the fprobe ops hash have been removed, that
tells ftrace that it wants to trace all functions.
Thus, this puts the state of the system where every function is
calling the fprobe callback handler (which does nothing as there
are no registered fprobes), but this causes a good 13% slow down of
the entire system.
Other updates:
- Add a selftest to test the above issues to prevent regressions.
- Fix preempt count accounting in function tracing
Better recursion protection was added to function tracing which
added another layer of preempt disable. As the preempt_count gets
traced in the event, it needs to subtract the amount of preempt
disabling the tracer does to record what the preempt_count was when
the trace was triggered.
- Fix memory leak in output of set_event
A variable is passed by the seq_file functions in the location that
is set by the return of the next() function. The start() function
allocates it and the stop() function frees it. But when the last
item is found, the next() returns NULL which leaks the data that
was allocated in start(). The m->private is used for something
else, so have next() free the data when it returns NULL, as stop()
will then just receive NULL in that case"
* tag 'ftrace-v6.14-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace:
tracing: Fix memory leak when reading set_event file
ftrace: Correct preemption accounting for function tracing.

fprobe: Fix accounting of when to unregister from function graph
fprobe: Always unregister fgraph function from ops
ftrace: Do not add duplicate entries in subops manager ops

The current test marks all unexpected return values as failed and sets ret
to 1. If a test is skipped, the entire test also returns 1, incorrectly
indicating failure.
To fix this, add a skipped variable and set ret to 4 if it was previously
0. Otherwise, keep ret set to 1.

A few bugs were found in the fprobe accounting logic along with it using
the function graph infrastructure. Update the fprobe selftest to catch
those bugs in case they or something similar shows up in the future.
The test now checks the enabled_functions file which shows all the
functions attached to ftrace or fgraph. When enabling a fprobe, make sure
that its corresponding function is also added to that file. Also add two
more fprobes to enable to make sure that the fprobe logic works properly
with multiple probes.

We use wait_port_listen() extensively to wait for a process
we spawned to be ready. Not all processes will open listening
sockets. Add a method of explicitly waiting for a child to
be ready. Pass a FD to the spawned process and wait for it
to write a message to us. FD number is passed via KSFT_READY_FD
env variable.
Similarly use KSFT_WAIT_FD to let the child process for a sign
that we are done and child should exit. Sending a signal to
a child with shell=True can get tricky.
Make use of this method in the queues test to make it less flaky.

Changes to MC remote need to be reflected in actual group memberships.
Add a test to verify that it is the case.

Instead of inlining equivalents, use lib.sh-provided primitives.
Use defer to manage vx lifetime.
This will make it easier to extend the test in the next patch.

This helper could be useful to more than just forwarding tests.
Move it upstairs and port over to log_test_skip().
Split the function into two parts: the bit that actually checks and
reports skip, which is in a new function check_command(). And a bit
that exits the test script if the check fails. This allows users
consistent checking behavior while giving an option to bail out from
a single test without bailing out of the whole script.

Verify that for a connectible AF_VSOCK socket, merely having a transport
assigned is insufficient; socket must be connected for the sockmap to
accept.
This does not test datagram vsocks. Even though it hardly matters. VMCI is
the only transport that features VSOCK_TRANSPORT_F_DGRAM, but it has an
unimplemented vsock_transport::readskb() callback, making it unsupported by
BPF/sockmap.

Commit 515745445e ("selftest/bpf: Add test for vsock removal from sockmap
on close()") added test that checked if proto::close() callback was invoked
on AF_VSOCK socket release. I.e. it verified that a close()d vsock does
indeed get removed from the sockmap.
It was done simply by creating a socket pair and attempting to replace a
close()d one with its peer. Since, due to a recent change, sockmap does not
allow updating index with a non-established connectible vsock, redo it with
a freshly established one.
