Constify methods of `std::net::SocketAddr`, `SocketAddrV4` and `SocketAddrV6` The following methods are made unstable const under the `const_socketaddr` feature (https://github.com/rust-lang/rust/issues/82485): ```rust // std::net impl SocketAddr { pub const fn ip(&self) -> IpAddr; pub const fn port(&self) -> u16; pub const fn is_ipv4(&self) -> bool; pub const fn is_ipv6(&self) -> bool; } impl SocketAddrV4 { pub const fn ip(&self) -> IpAddr; pub const fn port(&self) -> u16; } impl SocketAddrV6 { pub const fn ip(&self) -> IpAddr; pub const fn port(&self) -> u16; pub const fn flowinfo(&self) -> u32; pub const fn scope_id(&self) -> u32; } ``` Note: `SocketAddrV4::ip` and `SocketAddrV6::ip` use pointer casting and depend on the unstable feature `const_raw_ptr_deref`
2021-03-30Disallow octal format in Ipv4 stringCheng XU-1/+23
In its original specification, leading zero in Ipv4 string is interpreted as octal literals. So a IP address 0127.0.0.1 actually means 87.0.0.1. This confusion can lead to many security vulnerabilities. Therefore, in [IETF RFC 6943], it suggests to disallow octal/hexadecimal format in Ipv4 string all together. Existing implementation already disallows hexadecimal numbers. This commit makes Parser reject octal numbers. Fixes #83648. [IETF RFC 6943]: https://tools.ietf.org/html/rfc6943#section-3.1.1

2021-03-24Rollup merge of #83353 - m-ou-se:io-error-avoid-alloc, r=nagisaDylan DPC-2/+2
Add internal io::Error::new_const to avoid allocations. This makes it possible to have a io::Error containing a message with zero allocations, and uses that everywhere to avoid the *three* allocations involved in `io::Error::new(kind, "message")`. The function signature isn't perfect, because it needs a reference to the `&str`. So for now, this is just a `pub(crate)` function. Later, we'll be able to use `fn new_const<MSG: &'static str>(kind: ErrorKind)` to make that a bit better. (Then we'll also be able to use some ZST trickery if that would result in more efficient code.) See https://github.com/rust-lang/rust/issues/83352

Stabilize all stable methods of `Ipv4Addr`, `Ipv6Addr` and `IpAddr` as const This PR stabilizes all currently stable methods of `Ipv4Addr`, `Ipv6Addr` and `IpAddr` as const. Tracking issue: #76205 `Ipv4Addr` (`const_ipv4`): - `octets` - `is_loopback` - `is_private` - `is_link_local` - `is_multicast` - `is_broadcast` - `is_docmentation` - `to_ipv6_compatible` - `to_ipv6_mapped` `Ipv6Addr` (`const_ipv6`): - `segments` - `is_unspecified` - `is_loopback` - `is_multicast` - `to_ipv4` `IpAddr` (`const_ip`): - `is_unspecified` - `is_loopback` - `is_multicast` ## Motivation The ip methods seem like prime candidates to be made const: their behavior is defined by an external spec, and based solely on the byte contents of an address. These methods have been made unstable const in the beginning of September, after the necessary const integer arithmetic was stabilized. There is currently a PR open (#78802) to change the internal representation of `IpAddr{4,6}` from `libc` types to a byte array. This does not have any impact on the constness of the methods. ## Implementation Most of the stabilizations are straightforward, with the exception of `Ipv6Addr::segments`, which uses the unstable feature `const_fn_transmute`. The code could be rewritten to equivalent stable code, but this leads to worse code generation (#75085). This is why `segments` gets marked with `#[rustc_allow_const_fn_unstable(const_fn_transmute)]`, like the already const-stable `Ipv6Addr::new`, the justification being that a const-stable alternative implementation exists https://github.com/rust-lang/rust/pull/76206#issuecomment-685044184. ## Future posibilities This PR const-stabilizes all currently stable ip methods, however there are also a number of unstable methods under the `ip` feature (#27709). These methods are already unstable const. There is a PR open (#76098) to stabilize those methods, which could include const-stabilization. However, stabilizing those methods as const is dependent on `Ipv4Addr::octets` and `Ipv6Addr::segments` (covered by this PR).

Drop support for all cloudabi targets `cloudabi` is a tier-3 target, and [it is no longer being maintained upstream][no]. This PR drops supports for cloudabi targets. Those targets are: * aarch64-unknown-cloudabi * armv7-unknown-cloudabi * i686-unknown-cloudabi * x86_64-unknown-cloudabi Since this drops supports for a target, I'd like somebody to tag `relnotes` label to this PR. Some other issues: * The tidy exception for `cloudabi` crate is still remained because * `parking_lot v0.9.0` and `parking_lot v0.10.2` depends on `cloudabi v0.0.3`. * `parking_lot v0.11.0` depends on `cloudabi v0.1.0`.

replace `#[allow_internal_unstable]` with `#[rustc_allow_const_fn_unstable]` for `const fn`s `#[allow_internal_unstable]` is currently used to side-step feature gate and stability checks. While it was originally only meant to be used only on macros, its use was expanded to `const fn`s. This pr adds stricter checks for the usage of `#[allow_internal_unstable]` (only on macros) and introduces the `#[rustc_allow_const_fn_unstable]` attribute for usage on `const fn`s. This pr does not change any of the functionality associated with the use of `#[allow_internal_unstable]` on macros or the usage of `#[rustc_allow_const_fn_unstable]` (instead of `#[allow_internal_unstable]`) on `const fn`s (see https://github.com/rust-lang/rust/issues/69399#issuecomment-712911540). Note: The check for `#[rustc_allow_const_fn_unstable]` currently only validates that the attribute is used on a function, because I don't know how I would check if the function is a `const fn` at the place of the check. I therefore openend this as a 'draft pull request'. Closes rust-lang/rust#69399 r? @oli-obk
