1437: Add MS_LAZYTIME flag r=asomers a=ManaSugi MS_LAZYTIME (since Linux 4.0) reduces on-disk updates of inode timestamps (atime, mtime, ctime) by maintaining these changes only in memory. MS_LAZYTIME is available from `libc` v0.2.95. Signed-off-by: Manabu Sugimoto <Manabu.Sugimoto@sony.com> Co-authored-by: Manabu Sugimoto <Manabu.Sugimoto@sony.com>

2021-05-30Adapt aio to the world of async/await, and fix some potential unsoundness.Alan Somers
* libc::aiocb must not be moved while the kernel has a pointer to it. This change enforces that requirement by using std::pin. * Split LioCbBuilder out of LioCb. struct LioCb relied on the (incorrect) assumption that a Vec's elements have a stable location in memory. That's not true; they can be moved during Vec::push. The solution is to use a Vec in the new Builder struct, but finalize it to a boxed slice (which doesn't support push) before allowing it to be submitted to the kernel. * Eliminate owned buffer types. mio-aio no longer uses owned buffers with nix::aio. There's little need for it in the world of async/await. I'm not aware of any other consumers. This substantially simplifies the code.

2021-05-28Add sendfile64Tom Dryer
`sendfile64` is a Linux-specific call with a wider type for the `offset` argument than `sendfile`. This is largely a copy of the existing `sendfile` function and associated test.

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>

2021-04-07Fix spurious errors using `sendmmsg` with multiple cmsgsYuchen Wu
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.
2021-03-05Allow 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.
2021-03-04Remove accept4 on Android armAlan Somers
libc removed it in version 0.2.87. https://github.com/rust-lang/libc/pull/2079
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.

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.

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.
