2020-12-07Fix a use-after-free in execve_test_factoryAlan Somers
Ensure that the exec functions' arguments are valid for 'static. Previously they were short-lived temporaries.
2020-12-06Switch all builds from Travis to CirrusAlan Somers
Travis has been super-slow lately (> 6 hours per build). Cirrus is much faster: about 20 minutes. Cirrus also has slightly better test coverage, mainly because it doesn't use SECCOMP. Also, * Fix the Redox CI build. The old Travis configuration didn't actually build for Redox, so we never noticed that Redox can't be built with a stable compiler. Thanks to @coolreader18 for finding this. * Disable the udp_offload tests on cross-tested platforms. These tests are failing with ENOPROTOOPT in Cirrus-CI. I suspect it's due to a lack of support in QEMU. These tests were skipped on Travis because its kernel was too old. * Fix require_kernel_version on Cirrus-CI. Cirrus reports the Linux kernel version as 4.19.112+, which the semver crate can't handle. * Fix test_setfsuid on Cirrus. When run on Cirrus, it seems like the file in /tmp gets deleted as soon as it's closed. Probably an overzealous temporary file cleaner. Use /var/tmp, because no temporary file cleaner should run in there. * Skip mount tests on Cirrus. They fail for an unknown reason. Issue #1351 * Skip the AF_ALG tests on Cirrus-CI Issue #1352
2020-12-06Handle SIGRT_1 in test_alarmAlan Somers
When run in Cirrus-CI's environment, the tests generate copious SIGRT_1 signals. This commit ensures that test_alarm will ignore them.
2020-12-06Make the poll tests resilient against signalsAlan Somers
When run in Cirrus-CI's environment, the tests generate copious SIGRT_1 signals. This commit ensures that the poll tests will retry on EINTR.

2020-12-06Demote i686-apple-darwin to Tier 2Alan Somers
It's deprecated by Xcode, and the version of Xcode installed by Cirrus-CI doesn't include 32 bit libraries.

1345: Disable test-aio-drop in GNU environments r=asomers a=asomers This test occasionally fails in Travis on x86_64-unknown-linux-gnu. The failure takes the form of the test executable receiving a random signal. Sometimes SIGHUP, sometimes SIGKILL, etc. I think this must be a bug in glibc, even though I can't reproduce it in my development environment. But it interferes with CI too much to leave enabled.

1341: Fix recvmmsg(2) implementation r=asomers a=codeslinger There were two problems discovered with the `recvmmsg(2)` implementation that this changeset attempts to fix: 1. As mentioned in nix-rust/issues/1325, `recvmmsg(2)` can return fewer messages than requested, and 2. Passing the return value of `recvmmsg(2)` as the number of bytes in the messages received is incorrect. This changeset incorporates the proposed fix from nix-rust/issues/1325, as well as passing the correct value (`mmsghdr.msg_len`) for the number of bytes in a given message.

1318: KEEPCNT/KEEPINTVL aren't available on OpenBSD. r=asomers a=ltratt Without this commit, nix doesn't currently compile on OpenBSD. Some keepalive settings can be set globally, but not per-socket (see e.g. https://bugzilla.mozilla.org/show_bug.cgi?id=970550 for some digging into this). Since it seems that NetBSD and DragonflyBSD have these settings, it makes more sense to only exclude them on OpenBSD rather than include them on (pretty much every) other operating systems.

1296: DragonFlyBSD: use __errno_location now provided by the libc crate r=asomers a=cmusser Dragonfly recently (in Dfly 5.8) added an `__errno_location()` function to make it easy to access the thread-local `errno` variable. This has been exposed in rust-libc as of 0.2.77. This PR uses that functionality instead of the locally compiled C language shim, which the PR removes. One issue is backwards compatibilty. It requires 0.2.77 libc and DragonFly 5.8. Not sure how to gracefully handle older DragonFly versions, although I'm also not sure doing so is worth it.

1290: use subordinate terminal device for termios calls r=asomers a=jclulow The pseudo-terminal device handling tests in some places make tcgetattr(3C) and tcsetattr(3C) calls using the control/manager file descriptor rather than the subordinate terminal descriptor. This works on some systems, but not all; others such as illumos (and presumably Solaris) are more strict and require the termios requests be made against the terminal descriptor only.
