splice_short grows its pipe with (MAX_FRAGS + 1) * 0x1000 so it can
queue one short vmsplice() buffer for each fragment before draining the
pipe. That assumes 4K pipe buffers.
On 64K-page kernels the request is rounded to 262144 bytes, which
provides only four pipe buffers. The fifth one-byte vmsplice() blocks in
pipe_wait_writable and the test times out before it reaches the TLS path.
Request enough bytes for the same number of pipe buffers using the
runtime page size, and assert that the kernel granted at least that much.
If an unprivileged run cannot raise the pipe above the system
pipe-max-size limit, skip the test because it cannot exercise the
intended path.

In test_mutliproc(), when send() or recv() returns an error (e.g.,
-1), the test continues to execute the remaining code and fails
repeatedly due to using EXPECT_GE.
For example, if a TLS connection is broken and recv() returns -1,
EXPECT_GE(res, 0) records a failure but does not stop the test.
The test then proceeds with left -= res (where res = -1), causing
left to increase unexpectedly, and the loop continues indefinitely.
This results in a massive number of identical failure messages:
# tls.c:1686:mutliproc_sendpage_writers:Expected res (-1) >= 0 (0)
# tls.c:1686:mutliproc_sendpage_writers:Expected res (-1) >= 0 (0)
... (hundreds of identical failures)
Fix this by replacing EXPECT_GE with ASSERT_GE. When send() or recv()
fails, ASSERT_GE immediately aborts the current test, preventing
the subsequent undefined behavior and endless failure messages.

# data_steal: Test failed
# FAIL global.data_steal

The 10000 bytes read suggests that the child process did a recv()
of half of the data using the TLS ULP and we're now getting the
remaining half. The intent of the test is to get the child to
enter _TCP_ recvmsg handler, so it needs to enter the syscall before
parent installed the TLS recvmsg with setsockopt(SOL_TLS).
Instead of the 10msec sleep send 1 byte of data and wait for the
child to consume it.

This capability is critical for cloud environments, allowing hypervisors
to be updated with minimal downtime for running virtual machines. LUO
achieves this by preserving the state of selected resources, such as
memory, devices and their dependencies, across the kernel transition.
As a key feature, this series includes support for preserving memfd file

Looks like the 2msec sleep is not long enough. Make the sleep longer,
and then instead of second sleep wait for the thieving process to exit.
That way we can be sure it called recv() before us.
While at it also avoid trying to steal more than a record, this seems
to be causing issues in manual testing as well.

tls.sendmsg_large and tls.sendmsg_multiple are trying to send through
the self->cfd socket (only configured with TLS_RX) and to receive through
the self->fd socket (only configured with TLS_TX), so they're not using
kTLS at all. Swap the sockets.

As the recent patch is modifying the behaviour for TLS re MSG_EOR
handling we should be having a test for it.

TLS selftests use the ChaCha20-Poly1305 and SM4 algorithms, which are not
FIPS compliant. When fips=1, this set of tests fails. Add a check and only
run these tests if not in FIPS mode.

Other tests set up the connection fully on both ends before
communicating any data. Add a test which will queue up TLS
records to TCP before the TLS ULP is installed.

Add a handful of memory randomizations and precise length checks.
Nothing is really broken here, I did this to increase confidence
when debugging. It does fix a GCC warning, tho. Apparently GCC
recognizes that memory needs to be initialized for send() but
does not recognize that for write().

These are negative tests, testing TLS code rejects certain
operations. They won't pass without TLS enabled, pure TCP
accepts those operations.

Previous patch fixes overriding callbacks incorrectly. Triggering
the crash in sendpage_locked would be more spectacular but it's
hard to get to, so take the easier path of proving this is broken
and call getname. We're currently getting IPv4 socket info on an
IPv6 socket.
