2021-03-21cleanup: remove redundant unwrap in Dir::from_fdScott Lamb
2021-03-05Allow sockaddr_ll size mismatchJustin Ossevoort
Apparently the Linux kernel can return smaller sizes when the value in the last element of sockaddr_ll (`sll_addr`) is smaller than the declared size of that field.

2021-02-20pty: Make forkpty() unsafeTavian Barnes
After the child returns from a fork() of a multi-threaded process, it is undefined behaviour to call non-async-signal-safe functions according to POSIX. Since forkpty() is implemented in terms of fork(), those restrictions should apply to it too.

2020-12-09Fix intermittency in the doc test for alarmAlan Somers
On Cirrus CI, this test would sometimes fail, probably due to pause being awoken by SIGRT_1. sigwait is a superior alternative to pause. Fixes #1354
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

2020-11-27Fix recvmmsg(2) implementationToby DiPasquale
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.

2020-10-18KEEPCNT/KEEPINTVL aren't available on OpenBSD.Laurence Tratt
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.

I think @jabedude was working on this, but as there was no progress since May I went ahead and implemented it myself. I'm not completely sure about the cfg gates. Could we enable the functions for more targets? I'm also open for suggestions of better names for the new functions. Co-authored-by: Dominik Stolz <d.stolz@tum.de>

1278: Allow both &[CString] and &[&CStr] for sequence args in unistd r=asomers a=youknowone I am new to this project, so I wonder this kind of change is acceptable for the project or not. I agree taking `&[&CStr]` is the ideal way for the functions. But unfortunately, when users generate `CString`s from `&str`, they may get `&[CString]` rather than `&[&CStr]` Unlike single `CString` to `&CStr` argument, there is no easy way to convert `&[CString]` to `&[&CStr]` without creating new vector. By changing the type from `&[&CStr]` to `&[AsRef<CStr>]`, the args now can take both `&[CString]` and `&[&CStr]` without changing that much from nix.
