2021-10-09sockopt's Set and Get traits are not unsafeAlan Somers
They were properly marked as unsafe as originally written. However, when the internal mem::zeroed() was replaced by mem::uninitialized(), these traits actually became safe. Only Get::assume_init() is actually unsafe. Fixes a warning with the latest Clippy.

1538: posix_fadvise doesn't return -1 as sentinel value r=asomers a=ocadaruma ## Summary - `posix_fadvise(2)` does return error number directly (i.e. not through `errno`) * refs: https://man7.org/linux/man-pages/man2/posix_fadvise.2.html , https://man7.org/linux/man-pages/man2/posix_fadvise.2.html - However `posix_fadvise`-binding uses `Errno::result` to translate the error now, which is mis-use. 1545: Fix memory unsafety in unistd::getgrouplist r=asomers a=asomers Fixes #1541 1546: Revert "Expose SockAddr::from_raw_sockaddr" r=asomers a=asomers This reverts commit ed43d2c65e65dd68c9cf2dcf06f5ec45a44aaccd.

2021-09-28Fix return value of posix_fadviseHaruki Okada

1496: Rework UnixAddr to fix soundness issues r=asomers a=coolreader18 Fixes #1494 I went with making `sun_path` always nul-terminated since that just seems to make things easier, since (at least according to linux man pages) `sockaddr_un`s returned by the kernel will always be nul-terminated.

2021-09-08Make Errno::result() inlinelinkmauve
This makes the success case a single `cmpl $-1, %eax` followed with a non-taken conditional jump, instead of the current `callq` which is always taken. I have not benchmarked the difference, but it is an obvious improvement.

2021-09-07Implement AsRawFd for PollFdConrad Meyer
Implement the trait on PollFd, providing an `as_raw_fd()` accessor to get the RawFd associated with the PollFd. Subsumes #1147, #1286. Closes #1146. Test: `cargo test --test test test_pollfd_fd`
2021-09-06Add support for IP_RECVERR and IPV6_RECVERRConrad Meyer
Setting these options enables receiving errors, such as ICMP errors from the network, via `recvmsg()` with `MSG_ERRQUEUE`. Adds new `Ipv{4,6}RecvErr` variants to `ControlMessageOwned`. These control messages are produced when `Ipv4RecvErr` or `Ipv6RecvErr` options are enabled on a raw or datagram socket. New tests for the functionality can be run with `cargo test --test test test_recverr`. This commit builds on an earlier draft of the functionality authored by Matthew McPherrin <git@mcpherrin.ca>.
