2022-10-14reimplement recvmsg/sendmmsgMichael Baikov
New implementation performs no allocations after all the necessary structures are created, removes potentially unsound code that was used by the old version (see below) and adds a bit more documentation about bugs in how timeout is actually handled ``` let timeout = if let Some(mut t) = timeout { t.as_mut() as *mut libc::timespec } else { ptr::null_mut() }; ```
2022-10-14Update changelogMichael Baikov
2022-10-14pack_mhdr_to_receive: pass iovec ptr and capacity separatelyMichael Baikov
We'll be using that to reinitialize buffers later
2022-10-14pack_mhdr_to_receive: pass pointer and capacity directlyMichael Baikov
This is already an unsafe function, dealing with pointers directly does not make it much more unsafe but simplifies lifetimes later on and similar to a previous commit allows to alocate a single buffer to store all the control messages
2022-10-14socket: stop setting vector length inside read_mhdrMichael Baikov
CMSG_FIRSTHDR/CMSG_NEXTHDR operate in terms of pointers contained inside msghdr structure, vector capacity doesn't matter for them. This would change external behavior of recvmsg/recvmmsg in a sense that buffer passed to store controll messages won't have it's length updated but intended way to receive control messages is with cmsgs iterator on `RecvMsg` which would still work. This change is required to allow using a single vector to store control messages from multiple packets

1842: add eaccess on freebsd, dragonfly and linux r=rtzoeller a=SteveLauC #### man pages * [FreeBSD](https://www.freebsd.org/cgi/man.cgi?query=eaccess&sektion=2&n=1) * [DragonFly](https://man.dragonflybsd.org/?command=access&section=2) * [Linux](https://man7.org/linux/man-pages/man3/euidaccess.3.html) #### difference between `eaccess` and `access/faccessat` IMHO, `eaccess` uses effective identifiers to perform the permission check while `access/faccessat` use real IDs.

1839: Fix clippy warnings on nightly r=asomers a=rtzoeller Clippy is now smarter about detecting unnecessary casts and useless conversions, which means we need to be more explicit about when the conversions are needed for a subset of platforms. Required changes found by repeatedly running the following command against a list of the supported platforms. `xargs -t -I {} sh -c "cargo clippy -Zbuild-std --target {} --all-targets -- -D warnings || exit 255"` I removed the casts it complained about, and then restored them with an `#[allow]` if a later target needed the cast.
