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.

1390: pty: Make forkpty() unsafe r=asomers a=tavianator 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. Fixes #1388 Co-authored-by: Tavian Barnes <tavianator@tavianator.com>

1381: Close file descriptor on drop in TimerFd r=asomers a=crdumoul This change closes the TimerFd file descriptor on drop. Note that the TimerFd will no longer be `Clone` or `Copy`. Since it has a destructor it can't be `Copy`, and if it were `Clone` you could end up trying to use a closed TimerFd, or double-closing the file descriptor. Addresses #1379.

1368: Fix fcntl for FreeBSD platform r=asomers a=AlexanderThaller When compiling the following code with nix `0.19.1` under FreeBSD 12.2: ``` use std::os::unix::io::AsRawFd; fn main() { let f = std::fs::File::create("/tmp/testfile").unwrap(); nix::fcntl::posix_fadvise( f.as_raw_fd(), 0, 0, nix::fcntl::PosixFadviseAdvice::POSIX_FADV_NOREUSE, ).unwrap(); } ``` I get the following error: ``` error[E0433]: failed to resolve: could not find `PosixFadviseAdvice` in `fcntl` --> src/main.rs:10:21 | 10 | nix::fcntl::PosixFadviseAdvice::POSIX_FADV_NOREUSE, | ^^^^^^^^^^^^^^^^^^ could not find `PosixFadviseAdvice` in `fcntl` error[E0425]: cannot find function `posix_fadvise` in module `nix::fcntl` --> src/main.rs:6:17 | 6 | nix::fcntl::posix_fadvise( | ^^^^^^^^^^^^^ not found in `nix::fcntl` error: aborting due to 2 previous errors ``` Checking the documentation I noticed the documentation for the FreeBSD platform was missing: https://docs.rs/nix/0.19.1/x86_64-unknown-freebsd/nix/?search=PosixFadviseAdvice Checking the code I noticed that `target_env` was used instead of `target_os`: * https://doc.rust-lang.org/reference/conditional-compilation.html#target_env * https://doc.rust-lang.org/reference/conditional-compilation.html#target_os Switching to `target_os` fixed the compilation errors. I also ran the tests with the fix and they seemed to be fine: ``` test result: ok. 68 passed; 0 failed; 14 ignored; 0 measured; 0 filtered out ``` I hope this makes sense to fix.

2021-01-03Fix fcntl for FreeBSDAlexander Thaller
Need to use the right cfg option for the conditional compilation. target_os is the right option to use when targeting FreeBSD. target_env was used before which seems to be a typo.

1342: feat(unistd): Add getpeereid(3) r=asomers a=woodruffw `getpeereid(3)` is not POSIX, but it's present on many BSD-derived Unices. It's also the standard mechanism on those OSes for retrieving socket peer credentials (compare `getsockopt` + `SO_PEERCRED` on Linux, which `nix` already supports). Closes #1339.

1285: Add fuchsia support r=asomers a=amanda-tait This change adds support for the Fuchsia operating system to the nix crate. Fuchsia developers have a use case for nix, particularly its safe interfaces to the recvmsg(2) and sendmsg(2).
