1402: Support TIMESTAMPNS r=asomers a=WiSaGaN This adds support of linux TIMESTAMPNS. The code is mostly copied paste from https://github.com/nix-rust/nix/pull/663 Co-authored-by: Lu, Wangshan <wisagan@gmail.com>

1414: Fix corrupted sendmmsg() call r=asomers a=eaufavor Before this fix, the buffer that holds cmsgs may move due to the resize() call. That causes msg_hdr pointing to invalid memory, which ends up breaking the sendmmsg() call, resulting in EINVAL. This change fixes it by avoiding re-allocating the buffers.

2021-04-04Use memoffset::offset_of instead of homegrown macroAlan Somers
The homegrown macro was fine in 2016, but at some point it technically became UB. The memoffset crate does the same thing, but avoids UB when using rustc 1.51.0 or later. Fixes #1415

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.

1382: Don't implement Clone on Dir, SignalFd, and PtyMaster r=asomers a=asomers Since they close their file descriptors on Drop, it's almost impossible to use Clone without creating a double-close situation. Also, check for EBADF in SignalFd::drop and Dir::drop. Co-authored-by: Alan Somers <asomers@gmail.com>

2021-02-02Define *_MAGIC filesystem constants on Linux s390xJakob Naucke
Since rust-lang/libc is now using the correct data type on s390x (c_uint) for statfs constants, the s390x exemptions in the statfs MAGIC definitions like EXT4_SUPER_MAGIC can be removed. Signed-off-by: Jakob Naucke <jakob.naucke@ibm.com>

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.

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.
2020-07-04Expose IP_PKTINFO Control Message on AndroidBruno Tavares
The commit https://github.com/nix-rust/nix/pull/1222 added the very useful Ipv4PktInfo to allow `sendmsg` to define the origin of the ip. Unfortunattely, it didn't add the struct to Android target devices as well. This commit adds the `target_os = "android"` checks on the same place to allow the compilation to work for the following archs tested: - `cross build --target aarch64-linux-android` - `cross build --target x86_64-linux-android` - `cross build --target armv7-linux-androideabi` Also introduces iOS to allow using on libs for those platforms

2020-06-27Make SockAddr::as_ffi_pair safeAlan Somers
It was only marked unsafe because it did a pointer cast, but that particular pointer cast is always allowed by C.
2020-06-27Prefer to pass Inotify by value instead of by referenceAlan Somers
It's small and `Copy`, so pass by value is more efficient. This is technically a breaking change, but most code should compile without changes.
