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

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.

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.

2020-08-11use subordinate terminal device for termios callsJoshua M. Clulow
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.

2020-07-07Adding an implementation and some basic tests for timerfd.Vincent Dagonneau
Removed support for timerfd on Android as it seems to have been deprecated? See https://android.googlesource.com/platform/development/+/73a5a3b/ndk/platforms/android-20/include/sys/timerfd.h or https://github.com/rust-lang/libc/issues/1589 Removed the public status of `TimerSpec`, as it should not be exposed to the user. Implemented `FromRawFd` for `TimerFd` as it already implements `AsRawFd`. Addressed comments from the latest code review: - Removed upper bound assertions on timer expirations in tests. - Made the main example runnable and added code to show how to wait for the timer. - Refactored `ClockId` to use `libc_enum`. - Added comments for all public parts of the module. - Wrapped to 80 cols. - Changed the size of the buffer in the tests to the minimum required. * Ran rustfmt. * Added a `From` implementation for `libc::timespec` -> `TimeSpec`. * Reworked the example with the new changes and changed the timer from 5 to 1 second. * Added a constructor for a 0-initialized `TimerSpec`. * Added a new method to get the timer configured expiration (based on timerfd_gettime). * Added an helper method to unset the expiration of the timer. * Added a `wait` method to actually read from the timer. * Renamed `settime` into just `set`. * Refactored the tests and added a new one that tests both the `unset` and the `get` method. Modified CHANGELOG.

2020-06-26Add Ipv{4,6}PacketInfo support to ControlMessage for send{m,}msgPerry Lorier
This adds Ipv4PacketInfo and Ipv6PacketInfo to ControlMessage, allowing these to be used with sendmsg/sendmmsg. This change contains the following squashed commits: Add Ipv{4,6}PacketInfo to ControlMessage. Add documentation links to Ipv{4,6}PacketInfo Add changelog entry for Ipv{4,6}PacketInfo Add link to PR in the Changelog. Add extra build environments. Add tests for Ipv{4,6}PacketInfo. Swap #[test] and #[cfg] The CI appears to be running the test, even though it's not cfg'd for that platform. I _think_ this might be due to these being in the wrong order. So lets try swapping them. s/freebsd/netbsd/ for Ipv4PacketInfo netbsd supports in_pktinfo, not freebsd. Fix the cfg for Ipv{4,6}PacketInfo usage. Ah, I see what I did wrong. I had fixed the definitions, but I had the wrong cfg() in the usage. This has the usage match the definitions. Change SOL_IPV6 to IPPROTO_IPV6. FreeBSD doesn't have SOL_IPV6, but does have IPPROTO_IPV6, and the two constants are defined as being equal. So change to use IPPROTO_IPV6. Skip Ipv6PacketInfo test if v6 is not available. If IPv6 is not available, then when we try and bind to ip6-localhost, we'll get a EADDRNOTAVAIL, so skip the test. This should mean that the test will run on any machine that has a v6 loopback address. More architecture cfg() fixes. These all need to be the same, and they were not. Make them them all the same. Attempt III. Fix up mismatched cfg's again. Take IV. Make sure the cfg's that use a enum variant match the enum definition.

2020-05-26Fix build on OpenBSD caused by erroneous inclusion in allowed OS list for ↵Nick Pelone
sendmmsg() / recvmmsg() in #1208. In #1208, sendmmsg() / recvmmsg() were added, but OpenBSD(who doesn't support these) was included on the list of allowed operating systems for sendmmsg() related things. This broke the build on OpenBSD. For more Rust-world examples, see: https://github.com/rust-lang/libc/commit/6f6297301d49ff67b8ca044d651f36a56950298c

This is available only on Linux as far I know, [socket(7)](https://linux.die.net/man/7/socket) has some information about the `SO_BINDTODEVICE` sockopt. In simple words it binds a socket to an specific network device (specified as an string like "wlo1", "eth0", etc.), to only process packets from that device.

2019-10-28Fix sys::socket::recvfrom for TCP socketsAlan Somers
recvfrom(2) only returns the sender's address for protocols that provide it. Usually, that means it returns the sender's address for datagram sockets but not for stream sockets. Fixes #1144
2019-09-19Where relevant, replace equality checks in assert! with assert_eq!Xavier L'Heureux
`assert_eq!` gives more debug info when the test fails by default than `assert!`. This should help make debugging easier.
2019-09-19Fix test breakage in Seccomp mode.Alan Somers
Travis is now using Seccomp, and Docker's default Seccomp policy disables execveat (though, weirdly, not fexecve). It also prohibits any operations on AF_ALG sockets. While I'm here, replace close/dup with dup2, which is more reliable. Also, drop the fork mutex earlier. This way all of the exeve tests will run, even if one fails. https://docs.docker.com/engine/security/seccomp/

process_vm_readv requires it, and I'm not exactly sure which other things do too.

2019-09-03Replace most instances of mem::uninitialized with mem::MaybeUninitAlan Somers

2019-06-11Fix tests for abstract socketsBryant Mairs
Abstract paths should always be N-1 in length where N is the length of the `sun_path` field (first byte is \0). Given that, `UnixAddr::new_abstract()` should always return this N-1 length, not just the length of the string provided (the rest of the array will be \0s).
