2019-02-14Enable IPv4PacketInfo and Ipv6PacketInfo on more OSes.Alan Somers
This was an oversight from PR #1002
2019-02-14Fix misaligned references when using recvmsg with control messagesAlan Somers
On some platforms the alignment of cmsg_data could be less than the alignment of the messages that it contains. That led to unaligned reads on those platforms. This change fixes the issue by always copying the message contents into aligned objects. The change is not 100% backwards compatible when using recvmsg. Users may have to replace code like this: ```rust if let ControlMessage::ScmRights(&fds) = cmsg { ``` with this: ```rust if let ControlMessageOwned::ScmRights(fds) = cmsg { ``` Fixes #999
2019-02-14Replace CmsgSpace with a macroAlan Somers
CmsgSpace had three problems: 1) It would oversize buffers that expect multiple control messages 2) It didn't use the libc CMSG_SPACE(3) macro, so it might actually undersize a buffer for a single control message. 3) It could do bad things on drop, if you instantiate it with a type that implements Drop (which none of the currently supported ControlMessage types do). Fixes #994
2019-02-14Fix error handling of RecvMsgAlan Somers
There were two problems: 1) It would always return Ok, even on error 2) It could panic if there was an error, because sockaddr_storage_to_addr would be called on uninitialized memory.
2019-02-14Replace hand-rolled cmsg logic with libc's cmsg(3) functions.Alan Somers
Our hand-rolled logic had subtle alignment bugs that caused test_scm_rights to fail on OpenBSD (and probably could cause problems on other platforms too). Using cmsg(3) is much cleaner, shorter, and more portable. No user-visible changes.
2019-01-23Add IP_RECVIF & IP_RECVDSTADDR.Tom Pusateri
Include IP_PKTINFO and IP6_PKTINFO on netbsd/openbsd.
2019-01-06Make ScmTimestamp's doc test more robustAlan Somers
The old test made assumptions about the responsiveness of the test environment. The new test does not, and it's simpler too.

921: Get `SO_PEERCRED` working on all Linux targets r=asomers a=jonas-schievink These were disabled for ARM way back in 0db6ed1a28b4fb4d408cd9b7c4dba0a79bccf1f7 and 09c00ed7d9d92db2a79baa3ed212e7e239edceb9. Try to enable them for all arches and Android as well, since the removal wasn't really explained and I see no reason why this shouldn't work.

2018-06-01Remove emulation of FD_CLOEXEC/O_NONBLOCKBryant Mairs
Rather than using the native implementation of these constants on supported platforms, the native implementation was instead emulated. This was also hidden from the user even though this could result in data races and the functionality being broken. Native functionality is, however, not support on macos/ios. Rather than enable this emulation solely for this platform, it should be removed as this is a dangerous abstraction.

2018-04-10Refactor the ioctl API and documentationBryant Mairs
* Split `ioctl!` into separate macros. This makes documentation easier to read. * For every `ioctl_*!` macro include a description of the macro arguments as, the function prototype for the generated wrapper function, and an example if we have one. * Expose `request_code_*!` in the documentation to make the `ioctl_*_bad` macros easier to use. * Reorganize the file hierarchy to be simpler

799: Fix nix on Dragonfly r=Susurrus a=mneumann This commit replaces pull request https://github.com/nix-rust/nix/pull/684. It fixes building `nix` on DragonFly. All tests pass. This requires most recent libc to build: https://github.com/rust-lang/libc/pull/851.
2017-12-19Fix support for DragonFlyMichael Neumann
* DragonFly does not have a O_DSYNC flag * Fix type_of_cmsg_data on DragonFly * No fexecve() on DragonFly * Do not run aio test cases on DragonFly * Keep target lists in alphabetical order * Unscrable #[cfg] directives and use cfg_if! macro instead * Fix errno on DragonFly Below follows an explanation why we have to use a C extension to get errno working on DragonFly: DragonFly uses a thread-local errno variable, but #[thread_local] is feature-gated and not available in stable Rust as of this writing (Rust 1.21.0). We have to use a C extension (src/errno_dragonfly.c) to access it. Tracking issue for `thread_local` stabilization: https://github.com/rust-lang/rust/issues/29594 Once this becomes stable, we can remove build.rs, src/errno_dragonfly.c, remove the build-dependency from Cargo.toml, and use: extern { #[thread_local] static errno: c_int; } Now all targets will use the build.rs script, but only on DragonFly this will do something. Also, there are no additional dependencies for targets other than DragonFly (no gcc dep).
