2021-09-28[skip ci] Change release procedure to use cargo-releaseAlan Somers
Remove the example Cargo.toml entry from README.md because it's obvious, and it creates extra work at release time.

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.

1292: Support `TCP_MAXSEG` TCP Maximum Segment Size socket options r=asomers a=eaon Found myself in a situation where I needed to advertise a specific MSS. Thought this crate is the appropriate place for this feature (especially since the `TCP_MAXSEG` const was exposed through it before), so here goes. Actual change is of course tiny but it comes with a test. Happy to make changes, especially since I need to do more research on which platforms this works.

1317: test_af_alg_aead waits indefinitely r=asomers a=ritzk Starting with linux kernel 4.9, the crypto interface changed slightly such that the authentication tag memory is only needed in the output buffer for encryption and in the input buffer for decryption. Thus, we have fewer bytes to read than the buffer size. Do not block on read. alternatively, we can adjust the decrypted buffer size based on kernel version ( ">= 4.9") to not include auth_size . ``` if kernel_version >= "4.9": let mut decrypted = vec![0u8; payload_len + (assoc_size as usize) ]; ``` before ``` test sys::test_socket::test_af_alg_aead ... test sys::test_socket::test_af_alg_aead has been running for over 60 seconds ``` after ``` test sys::test_socket::test_af_alg_aead ... ok ``` Co-authored-by: Ritesh Khadgaray <khadgaray@gmail.com>

1514: Add support for IP_RECVERR r=asomers a=cemeyer This pull request adds support for setting the `IP_RECVERR` (and corresponding `IPV6_RECVERR`) sockopt, and then decoding the resulting control messages from `recvmsg()`. It is a Linux-specific API. This PR extends #1161 by: * Making the address associated with a `IpvXRecvErr` control message optional (`recvmsg` documentation claims it is not provided for some kinds of error), per `@WGH-.` * Adding basic tests for both IPv4 and IPv6 (blat a UDP packet at a hopefully-unoccupied port on localhost and observe ICMP port unreachable). * Adding a Changelog entry. I added some trivial doc comments on the `ControlMessageOwned` variants, but I'm not sure exactly what documentation you had in mind earlier on #1161. Co-authored-by: Conrad Meyer <cem@FreeBSD.org>
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>.
