Linux [1], FreeBSD [2] and the Open Group [3] manuals for both setsid and setpgrp state that the calling process will be assigned a process group ID that matches its process ID so check that's the case in the test by calling getpgid on the child process ID. on QNX8 (as of GA8.0.2) libc::kill(pgid) appears unable to terminate the child process so skip that check on that target as it's behavior that libstd provides no API for [1]: https://man7.org/linux/man-pages/man2/setsid.2.html [2]: https://man.freebsd.org/cgi/man.cgi?query=setsid&sektion=2 [3]: https://pubs.opengroup.org/onlinepubs/000095399/functions/setsid.html
also extend the existing tests to exercise the getsockname(2) and getpeername(2) paths with both named and unnamed Unix sockets

Additional fixes library/std after earlier PR renamed some targets
Standardise on QNX SDP, because that's the thing you install and build against. QNX Neutrino and QNX OS are run-time details that are chosen for you by the SDP you have installed.
Tests ignored on target_os = "nto" should also be ignored on target_os = "qnx".
cc-rs now knows about QNX so the environment isn't required

There was a problem hiding this comment.
question: This seems like a fairly big discrepancy - does this cause issues with user-facing process APIs as well?

@aapoalas short answer: no; longer answer:
- AFAICT, this only affects
killwith negative arguments to send the signal to a whole process group - the libstd does not expose a public API that does
kill(-pgid)to terminate a process group; only these tests are usinglibc::kill(-pgid) - we believe this could be a bug in the QNX8 kernel or userspace given that the test does pass (i.e.
kill(-pgid)works) on QNX7.1 (target_os="nto") and have reported the issue to Blackberry - we have seen no test failures in any other libstd test that uses the
libc::killAPI, e.g.std::process::tests

This PR contains libstd fixes so libstd can be build for QNX SDP 8.
It requires patches to libc-0.2 and cc-rs. The cc-rs patch was merged already. I have a patch for libc-1.0 here which will need backporting to libc-0.2 once merged.
With these in place, I was able to remotely
test tests/ui library/std library/alloc library/coreforx86_64-pc-qnxusing a remote-test-server running on QNX SDP 8.0's QEMU BSP image. The only tests that failed were the twotests/ui/codegen/huge-stacks.rstests, and I did not have enough RAM to run them.
