Don't hard-code x86 specific names. Rather, use vdso_config definitions
to find the correct function matching the architecture.
Add random VDSO function names in names[][]. Remove the #ifdef
CONFIG_VDSO32, as having the name there all the time is harmless and
guaranties a steady index for following strings.

This is due to kernel include/linux/limits.h being included instead of
libc's limits.h.
This is because directory include/ is added through option -isystem so
it goes prior to glibc's include directory.
Replace -isystem by -idirafter.
But this implies that now tools/include/linux/linkage.h is included
instead of include/linux/linkage.h, so define a stub for
SYM_FUNC_START() and SYM_FUNC_END().

Rather than using pthread_get/set_specific, just use gcc's __thread
annotation, which is noticeably faster and makes the code more obvious.
Also, just have one simplified struct called vgrnd, instead of trying to
split things up semantically. Those divisions were useful when this code
was split across several commit *messages*, but doesn't make as much
sense within a single file. This should make the code more clear and
provide a better example for implementers.

The test case for SME vector length changes via sigreturn use a bit too
much cut'n'paste and only actually changed the SVE vector length in the
test itself. Andre's recent factoring out of the initialisation code caused
this to be exposed and the test to start failing. Fix the test to actually
cover the thing it's supposed to test.

This test extends "delete re-add signal" to validate the previous
commit: when the 'signal' endpoint linked to the initial subflow (ID 0)
is re-added multiple times, it will re-send the ADD_ADDR with id 0. The
client should still be able to re-create this subflow, even if the
add_addr_accepted limit has been reached as this special address is not
considered as a new address.

The initial subflow has a special local ID: 0. It is specific per
connection.
When a global endpoint is deleted and re-added later, it can have a
different ID, but the kernel should still use the ID 0 if it corresponds
to the initial address.
This test validates this behaviour: the endpoint linked to the initial
subflow is removed, and re-added with a different ID.
Note that removing the initial subflow will not decrement the 'subflows'
counters, which corresponds to the *additional* subflows. On the other
hand, when the same endpoint is re-added, it will increment this
counter, as it will be seen as an additional subflow this time.

Thanks to the previous commit, the MPTCP subflows are now closed on both
directions even when only the MPTCP path-manager of one peer asks for
their closure.
In the two tests modified here -- "userspace pm add & remove address"
and "userspace pm create destroy subflow" -- one peer is controlled by
the userspace PM, and the other one by the in-kernel PM. When the
userspace PM sends a RM_ADDR notification, the in-kernel PM will
automatically react by closing all subflows using this address. Now,
thanks to the previous commit, the subflows are properly closed on both
directions, the userspace PM can then no longer closes the same
subflows if they are already closed. Before, it was OK to do that,
because the subflows were still half-opened, still OK to send a RM_ADDR.
In other words, thanks to the previous commit closing the subflows, an
error will be returned to the userspace if it tries to close a subflow
that has already been closed. So no need to run this command, which mean
that the linked counters will then not be incremented.
These tests are then no longer sending both a RM_ADDR, then closing the
linked subflow just after. The test with the userspace PM on the server
side is now removing one subflow linked to one address, then sending
a RM_ADDR for another address. The test with the userspace PM on the
client side is now only removing the subflow that was previously
created.

Setup trace points, add a new ftrace instance in order to not interfere
with the rest of the system, filtering by net namespace cookies.
Raise a new background thread that parses trace_pipe, matches them with
the list of expected events.
Wiring up trace events to selftests provides another insight if there is
anything unexpected happining in the tcp-ao code (i.e. key rotation when
it's not expected).
Note: in real programs libtraceevent should be used instead of this
manual labor of setting ftrace up and parsing. I'm not using it here
as I don't want to have an .so library dependency that one would have to
bring into VM or DUT (Device Under Test). Please, don't copy it over

On tests that are expecting failure the timeout value is
TEST_RETRANSMIT_SEC == 1 second. Which is big enough for most of devices
under tests. But on a particularly slow machine/VM, 1 second might be
not enough for another thread to be scheduled and attempt to connect().
It is not a problem for tests that expect connect() to succeed as
the timeout value for them (TEST_TIMEOUT_SEC) is intentionally bigger.
One obvious way to solve this would be to increase TEST_RETRANSMIT_SEC.
But as all tests would increase the timeouts, that's going to sum up.
But here is less obvious way that keeps timeouts for expected connect()
failures low: just synchronize the two threads, which will assure that
before counter checks the other thread got a chance to run and timeout
on connect(). The expected increase of the related counter for listen()
socket will yet test the expected failure.
Never happens on my machine, but I suppose the majority of netdev's
connect-deny-* flakes [1] are caused by this.

It's not safe to use '%zu' specifier for printing uint64_t on 32-bit

It turns to be that open_netns() is called rarely from the child-thread
and more often from parent-thread. Yet, on initialization of kconfig
checks, either of threads may reach kconfig_lock mutex first.
VRF-related checks do create a temporary ksft-check VRF in
an unshare()'d namespace and than setns() back to the original.
As original was opened from "/proc/self/ns/net", it's valid for
thread-leader (parent), but it's invalid for the child, resulting
in the following failure on tests that check has_vrfs() support:
> # ok 54 TCP-AO required on socket + TCP-MD5 key: prefailed as expected: Key was rejected by service
> # not ok 55 # error 381[unsigned-md5.c:24] Failed to add a VRF: -17
> # not ok 56 # error 383[unsigned-md5.c:33] Failed to add a route to VRF: -22: Key was rejected by service
> not ok 1 selftests: net/tcp_ao: unsigned-md5_ipv6 # exit=1
Use "/proc/thread-self/ns/net" which is valid for any thread.

Most of the functions in tcp-ao lib/ return negative errno or -1 in case
of a failure. That creates inconsistencies in lib/kconfig, which saves
what was the error code. As well as the uninitialized kconfig value is
-1, which also may be the result of a check.
Define KCONFIG_UNKNOWN and save negative return code, rather than
libc-style errno.

Instead of pre-allocating a fixed-sized buffer of TEST_MSG_BUFFER_SIZE
and printing into it, call vsnprintf() with str = NULL, which will
return the needed size of the buffer. This hack is documented in
man 3 vsnprintf.
Essentially, in C++ terms, it re-invents std::stringstream, which is
going to be used to print different tracing paths and formatted strings.
Use it straight away in __test_print() - which is thread-safe version of
printing in selftests.

Adds a selftest that creates two virtual interfaces, assigns one to a
new namespace, and assigns IP addresses to both.
It listens on the destination interface using socat and configures a
dynamic target on netconsole, pointing to the destination IP address.
The test then checks if the message was received properly on the
destination interface.

On some machines with a large number of CPUs there is a sizable delay
between an atomic replace occurring and when sysfs updates accordingly.

This results in passing 0 or just IOMMU_CACHE to iommu_map(). Most of
the page table formats don't like this:
amdv1 - -EINVAL
armv7s - returns 0, doesn't update mapped
arm-lpae - returns 0 doesn't update mapped
dart - returns 0, doesn't update mapped
VT-D - returns -EINVAL
Unfortunately the three formats that return 0 cause serious problems:
- Returning ret = but not uppdating mapped from domain->map_pages()
causes an infinite loop in __iommu_map()
- Not writing ioptes means that VFIO/iommufd have no way to recover them
and we will have memory leaks and worse during unmap
Since almost nothing can support this, and it is a useless thing to do,
block it early in iommufd.

Currently a number of SVE/SME related tests have almost identical
functions to enumerate all supported vector lengths. However over time
the copy&pasted code has diverged, allowing some bugs to creep in:
- fake_sigreturn_sme_change_vl reports a failure, not a SKIP if only
one vector length is supported (but the SVE version is fine)
- fake_sigreturn_sme_change_vl tries to set the SVE vector length, not
the SME one (but the other SME tests are fine)
- za_no_regs keeps iterating forever if only one vector length is
supported (but za_regs is correct)
Since those bugs seem to be mostly copy&paste ones, let's consolidate
the enumeration loop into one shared function, and just call that from
each test. That should fix the above bugs, and prevent similar issues
from happening again.
