Three ways the bounds added here failed to do their job:
- get_first_free_port ended the scan cap with 'exit 1', but every caller
runs it in a command substitution, so only the subshell died. The port
variable came back empty, the next $((port + 1)) evaluated to 1, and the
run limped on to a confusing wait_for_readyFile failure. Forcing the cap
on ocsp-stapling.test: before, the script ran on and hung until an outer
timeout killed it; now it exits 1 at the error. Return instead, and check
the status at all 25 call sites across the six scripts.
- The macOS timeout shim was a shell function. Backgrounding a function
forks a subshell, so $! was the subshell and cleanup killed that while
the server it was meant to stop leaked. Use a prefix variable that
expands to nothing when timeout(1) is absent, keeping $! the real pid.
- timeout -s KILL exits 137, not 124. Sites that read $? and treat any
non-zero as 'feature not compiled in' turned a hang into exit 0, so the
bound made a hang less visible than before. Add timed_out() and check it
before those skip branches; use it for the version probes too, which
matched any status >= 124.
The scripts that wait for a server to publish its ready file declare
counter at file scope and never reset it, so the retry budget is shared
by every server start in the script instead of applying to each one.
Once the early cases have used it up, every later create_port() falls
straight through to "NO ready file ending test", kills a server that was
starting normally, and the client then fails with "port number cannot be
0". Retry loops do not help, since the budget is already spent when they
run.
The failure needs only a build whose server start-up is slow enough to
consume a few tenths of a second each time. It showed up in the FIPS
dev-no-POST kernel-settings-all-pqc-asm job, where the server pays for
the CASTs, the PQC algorithms and the vector-register fallback fuzzer:
psk.test gave up after exactly 20 waits and tls13.test after exactly 51,
both the full script budget rather than a per-case one.
Reset counter where the wait begins, which is what the ocsp-stapling
scripts already do. Reproduced with a wrapper that delays the server by
one second: psk.test then fails on its third case before the change and
passes after it.
timeout(1) is GNU coreutils and is not installed on macOS, so the
"make check macos" job failed with "timeout: command not found" for
every wrapped server. Add a small shim to each affected test: when
timeout is unavailable (e.g. macOS) run the server unbounded, restoring
the prior macOS behavior. The flaky hang the timeout guards against is on
the Linux-only trackmemory job, so macOS does not need the bound.
Several test scripts share the same pattern as ocsp-stapling_tls13multi:
a backgrounded example server is "wait"ed on with no timeout, so a
server that flakily fails to exit blocks the script until the CI job
timeout. Wrap those servers in "timeout -s KILL 2m" as well.
Scripts: ocsp-stapling, ocsp-stapling2,
ocsp-stapling-with-wolfssl-responder, crl-revoked, tls13, resume,
pkcallbacks, dtlscid.
Correct the logic for checking if the client and server examples are compiled
in the test scripts. The previous logic was inverted, causing the tests to
always skip if the examples *were* compiled.
Mostly combinations of NO_WOLFSSL_CLIENT, NO_WOLFSSL_SERVER and
WOLFSSL_NO_CLIENT_AUTH were failing.
Added configurations to CI loop.
