1622: Introduce `timer_*` support r=asomers a=blt This commit adds support for the signal timer mechanism in POSIX, the mirror to timerfd on Linux. I wasn't _quite_ sure of how to fit into the project organization but hopefully this patch isn't too far off. Resolves #1424 Signed-off-by: Brian L.

1618: Refactor UnixAddr r=asomers a=asomers * Within UnixAddr, replace the path_len variable (length of the sun_path field) with sun_len (length of the whole structure). This is more similar to how other sockaddr types work, and it's the same way that the BSDs use the sun_len field. Also, don't require that sun_path be nul-terminated. The OS doesn't require it. * On BSD-derived operating systems, struct sockaddr has a sa_len field that holds the length of the structure. UnixAddr's path_len field is redundant. Remove path_len on BSD-derived OSes, retaining it only for Illumos and Linux-based OSes. Co-authored-by: Alan Somers <asomers@gmail.com>

2021-12-30Optimize UnixAddr for the BSDsAlan Somers
On BSD-derived operating systems, struct sockaddr has a sa_len field that holds the length of the structure. UnixAddr's path_len field is redundant. Remove path_len on BSD-derived OSes, retaining it only for Illumos and Linux-based OSes. Also, ensure that two UnixAddrs compare equal if they differ only by the presence of a trailing NUL. On Linux, syscalls like getsockname add a trailing NUL to the sockaddr they return, even if no NUL was present on the sockaddr originally passed to the kernel via a syscall like bind, and even though the docs explicitly say that any NUL passed to bind is not considered to be part of the address. Work around this bug by stripping it in UnixAddrKind::get(), so that at least two UnixAddrs will compare identical even if they differ in the presence of a trailing NUL.

1596: Add NetBSD configuration for supported process resources r=asomers a=schctl In addition to existing resources, NetBSD supports `RLIMIT_MEMLOCK`, `RLIMIT_NPROC` and `RLIMIT_RSS`. https://man.netbsd.org/setrlimit.2 `RLIMIT_AS` is also supported, but it looks like it was added [after version 5.0](https://mail-index.netbsd.org/tech-kern/2009/03/28/msg004702.html), so I'm not sure if that should be enabled. 1621: Add posix_fallocate on DragonFly r=asomers a=rtzoeller Enable the existing `posix_fallocate()` tests as they are passing locally.

2021-12-21Improve the sockaddr interface:Alan Somers
* All sockaddr newtypes should be repr(transparent) * All sockaddr newtypes should be opaque, so the user can't do something like change the sa_family field in a way that violates invariants. This is a prerequisite for #1544.

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.

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>.
