   openSUSE Security Update: Security update for rust, rust-cbindgen
______________________________________________________________________________

Announcement ID: openSUSE-SU-2020:0933-1
Rating: moderate
References: #1115645 #1154817 #1173202
Cross-References: CVE-2020-1967
Affected Products:
openSUSE Leap 15.1
______________________________________________________________________________

An update that solves one vulnerability and has two fixes
is now available.

Description:

This update for rust, rust-cbindgen fixes the following issues:

rust was updated for use by Firefox 76ESR.

- Fixed miscompilations with rustc 1.43 that lead to LTO failures
(bsc#1173202)

Update to version 1.43.1

- Updated openssl-src to 1.1.1g for CVE-2020-1967.
- Fixed the stabilization of AVX-512 features.
- Fixed `cargo package --list` not working with unpublished dependencies.

Update to version 1.43.0

+ Language:

- Fixed using binary operations with `&{number}` (e.g. `&1.0`) not
having
the type inferred correctly.
- Attributes such as `#[cfg()]` can now be used on `if` expressions.
- Syntax only changes:
* Allow `type Foo: Ord` syntactically.
* Fuse associated and extern items up to defaultness.
* Syntactically allow `self` in all `fn` contexts.
* Merge `fn` syntax + cleanup item parsing.
* `item` macro fragments can be interpolated into `trait`s, `impl`s, and
`extern` blocks. For example, you may now write: ```rust macro_rules!
mac_trait { ($i:item) => { trait T { $i } } } mac_trait! { fn foo()
{}
} ```
* These are still rejected *semantically*, so you will likely receive an
error but these changes can be seen and parsed by macros and
conditional compilation.

+ Compiler

- You can now pass multiple lint flags to rustc to override the previous
flags.

For example; `rustc -D unused -A unused-variables` denies everything in
the `unused` lint group except `unused-variables` which is explicitly
allowed. However, passing `rustc -A unused-variables -D unused` denies
everything in the `unused` lint group **including** `unused-variables`
since the allow flag is specified before the deny flag (and therefore
overridden).
- rustc will now prefer your system MinGW libraries over its bundled
libraries if they are available on `windows-gnu`.
- rustc now buffers errors/warnings printed in JSON.

Libraries:

- `Arc<[T; N]>`, `Box<[T; N]>`, and `Rc<[T; N]>`, now
implement
`TryFrom<Arc<[T]>>`,`TryFrom<Box<[T]>>`, and
`TryFrom<Rc<[T]>>`
respectively.
**Note** These conversions are only available when `N` is `0..=32`.
- You can now use associated constants on floats and integers directly,
rather than having to import the module. e.g. You can now write
`u32::MAX` or `f32::NAN` with no imports.
- `u8::is_ascii` is now `const`.
- `String` now implements `AsMut<str>`.
- Added the `primitive` module to `std` and `core`. This module reexports
Rust's primitive types. This is mainly useful in macros where you want
avoid these types being shadowed.
- Relaxed some of the trait bounds on `HashMap` and `HashSet`.
- `string::FromUtf8Error` now implements `Clone + Eq`.

+ Stabilized APIs

- `Once::is_completed`
- `f32::LOG10_2`
- `f32::LOG2_10`
- `f64::LOG10_2`
- `f64::LOG2_10`
- `iter::once_with`

+ Cargo

- You can now set config `[profile]`s in your `.cargo/config`,
or through your environment.
- Cargo will now set `CARGO_BIN_EXE_<name>` pointing to a
binary's
executable path when running integration tests or benchmarks.
`<name>`
is the name of your binary as-is e.g. If you wanted the executable
path for a binary named `my-program`you would use
`env!("CARGO_BIN_EXE_my-program")`.

+ Misc

- Certain checks in the `const_err` lint were deemed unrelated to const
evaluation, and have been moved to the `unconditional_panic` and
`arithmetic_overflow` lints.

+ Compatibility Notes

- Having trailing syntax in the `assert!` macro is now a hard error.
This has been a warning since 1.36.0.
- Fixed `Self` not having the correctly inferred type. This incorrectly
led to some instances being accepted, and now correctly emits a hard
error.

Update to version 1.42.0:

+ Language

- You can now use the slice pattern syntax with subslices.
- You can now use #[repr(transparent)] on univariant enums. Meaning that
you can create an enum that has the exact layout and ABI of the type
it contains.
- There are some syntax-only changes:
* default is syntactically allowed before items in trait definitions.
* Items in impls (i.e. consts, types, and fns) may syntactically leave
out their bodies in favor of ;.
* Bounds on associated types in impls are now syntactically allowed
(e.g. type Foo: Ord;).
* ... (the C-variadic type) may occur syntactically directly as the
type of any function parameter. These are still rejected
semantically, so you will likely receive an error but these changes
can be seen and parsed by procedural macros and conditional
compilation.

+ Compiler

- Added tier 2 support for armv7a-none-eabi.
- Added tier 2 support for riscv64gc-unknown-linux-gnu.
- Option::{expect,unwrap} and Result::{expect, expect_err, unwrap,
unwrap_err} now produce panic messages pointing to the location where
they were called, rather than core's internals. Refer to Rust's
platform support page for more information on Rust's tiered platform
support.

+ Libraries

- iter::Empty<T> now implements Send and Sync for any T.
- Pin::{map_unchecked, map_unchecked_mut} no longer require the return
type to implement Sized.
- io::Cursor now derives PartialEq and Eq.
- Layout::new is now const.
- Added Standard Library support for riscv64gc-unknown-linux-gnu.

+ Stabilized APIs

- CondVar::wait_while
- CondVar::wait_timeout_while
- DebugMap::key
- DebugMap::value
- ManuallyDrop::take
- matches!
- ptr::slice_from_raw_parts_mut
- ptr::slice_from_raw_parts

+ Cargo

- You no longer need to include extern crate proc_macro; to be able to
use proc_macro; in the 2018 edition.

+ Compatibility Notes

- Error::description has been deprecated, and its use will now produce a
warning. It's recommended to use Display/to_string instead.

Update to version 1.41.1:

- Always check types of static items
- Always check lifetime bounds of `Copy` impls
- Fix miscompilation in callers of `Layout::repeat`

Update to version 1.41.0:

+ Language

- You can now pass type parameters to foreign items when implementing
traits. E.g. You can now write `impl<T> From<Foo> for
Vec<T> {}`.
- You can now arbitrarily nest receiver types in the `self` position.
E.g. you can now write `fn foo(self: Box<Box<Self>>) {}`.
Previously
only `Self`, `&Self`, `&mut Self`, `Arc<Self>`,
`Rc<Self>`, and
`Box<Self>` were allowed.
- You can now use any valid identifier in a `format_args` macro.
Previously identifiers starting with an underscore were not allowed.
- Visibility modifiers (e.g. `pub`) are now syntactically allowed on
trait items and enum variants. These are still rejected semantically,
but can be seen and parsed by procedural macros and conditional
compilation.

+ Compiler

- Rustc will now warn if you have unused loop `'label`s.
- Removed support for the `i686-unknown-dragonfly` target.
- Added tier 3 support\* for the `riscv64gc-unknown-linux-gnu` target.
- You can now pass an arguments file passing the `@path` syntax to
rustc. Note that the format differs somewhat from what is found in
other tooling; please see the documentation for more information.
- You can now provide `--extern` flag without a path, indicating that it
is available from the search path or specified with an `-L` flag.

Refer to Rust's [platform support page][forge-platform-support] for
more
information on Rust's tiered platform support.

+ Libraries

- The `core::panic` module is now stable. It was already stable through
`std`.
- `NonZero*` numerics now implement `From<NonZero*>` if it's a
smaller
integer width. E.g. `NonZeroU16` now implements `From<NonZeroU8>`.
- `MaybeUninit<T>` now implements `fmt::Debug`.

+ Stabilized APIs

- `Result::map_or`
- `Result::map_or_else`
- `std::rc::Weak::weak_count`
- `std::rc::Weak::strong_count`
- `std::sync::Weak::weak_count`
- `std::sync::Weak::strong_count`

+ Cargo

- Cargo will now document all the private items for binary crates by
default.
- `cargo-install` will now reinstall the package if it detects that it
is out
of date.
- Cargo.lock now uses a more git friendly format that should help to
reduce merge conflicts.
- You can now override specific dependencies's build settings. E.g.
`[profile.dev.package.image] opt-level = 2` sets the `image` crate's
optimisation level to `2` for debug builds. You can also use
`[profile.<profile>.build-override]` to override build scripts
and
their dependencies.

+ Misc

- You can now specify `edition` in documentation code blocks to compile
the block for that edition. E.g. `edition2018` tells rustdoc that the
code sample should be compiled the 2018 edition of Rust.
- You can now provide custom themes to rustdoc with `--theme`, and check
the current theme with `--check-theme`.
- You can use `#[cfg(doc)]` to compile an item when building
documentation.

+ Compatibility Notes

- As previously announced 1.41.0 will be the last tier 1 release for
32-bit Apple targets. This means that the source code is still
available to build, but the targets are no longer being tested and
release binaries for those platforms will no longer be distributed by
the Rust project. Please refer to the linked blog post for more
information.

- Bump version of libssh2 for SLE15; we now need a version with
libssh2_userauth_publickey_frommemory(), which appeared in libssh2 1.6.0.

Update to version 1.40.0

+ Language

- You can now use tuple `struct`s and tuple `enum` variant's
constructors in `const` contexts. e.g. pub struct Point(i32, i32);
const ORIGIN: Point = { let constructor = Point; constructor(0, 0) };
- You can now mark `struct`s, `enum`s, and `enum` variants with the
`#[non_exhaustive]` attribute to indicate that there may be variants
or fields added in the future. For example this requires adding a
wild-card branch (`_ => {}`) to any match statements on a
non-exhaustive `enum`.
- You can now use function-like procedural macros in `extern` blocks and
in type positions. e.g. `type Generated = macro!();`
- Function-like and attribute procedural macros can now emit
`macro_rules!` items, so you can now have your macros generate macros.
- The `meta` pattern matcher in `macro_rules!` now correctly matches the
modern attribute syntax. For example `(#[$m:meta])` now matches
`#[attr]`, `#[attr{tokens}]`, `#[attr[tokens]]`, and `#[attr(tokens)]`.

+ Compiler

- Added tier 3 support\* for the `thumbv7neon-unknown-linux-musleabihf`
target.
- Added tier 3 support for the `aarch64-unknown-none-softfloat` target.
- Added tier 3 support for the `mips64-unknown-linux-muslabi64`, and
`mips64el-unknown-linux-muslabi64` targets.

+ Libraries

- The `is_power_of_two` method on unsigned numeric types is now a
`const` function.

+ Stabilized APIs

- BTreeMap::get_key_value
- HashMap::get_key_value
- Option::as_deref_mut
- Option::as_deref
- Option::flatten
- UdpSocket::peer_addr
- f32::to_be_bytes
- f32::to_le_bytes
- f32::to_ne_bytes
- f64::to_be_bytes
- f64::to_le_bytes
- f64::to_ne_bytes
- f32::from_be_bytes
- f32::from_le_bytes
- f32::from_ne_bytes
- f64::from_be_bytes
- f64::from_le_bytes
- f64::from_ne_bytes
- mem::take
- slice::repeat
- todo!

+ Cargo

- Cargo will now always display warnings, rather than only on fresh
builds.
- Feature flags (except `--all-features`) passed to a virtual workspace
will now produce an error. Previously these flags were ignored.
- You can now publish `dev-dependencies` without including a `version`.

+ Misc

- You can now specify the `#[cfg(doctest)]` attribute to include an item
only when running documentation tests with `rustdoc`.

+ Compatibility Notes

- As previously announced, any previous NLL warnings in the 2015 edition
are now hard errors.
- The `include!` macro will now warn if it failed to include the entire
file. The `include!` macro unintentionally only includes the first
_expression_ in a file, and this can be unintuitive. This will become
either a hard error in a future release, or the behavior may be fixed
to include all expressions as expected.
- Using `#[inline]` on function prototypes and consts now emits a
warning under `unused_attribute` lint. Using `#[inline]` anywhere else
inside traits
or `extern` blocks now correctly emits a hard error.

Update to version 1.39.0

+ Language

- You can now create async functions and blocks with async fn, async
move {}, and async {} respectively, and you can now call .await on
async expressions.
- You can now use certain attributes on function, closure, and function
pointer parameters.
- You can now take shared references to bind-by-move patterns in the if
guards of match arms.

+ Compiler

- Added tier 3 support for the i686-unknown-uefi target.
- Added tier 3 support for the sparc64-unknown-openbsd target.
- rustc will now trim code snippets in diagnostics to fit in your
terminal.
- You can now pass --show-output argument to test binaries to print the
output of successful tests.

+ For more details:
https://github.com/rust-lang/rust/blob/stable/RELEASES.md#version-1390-2019
-11-07

- Switch to bundled version of libgit2 for now. libgit2-sys seems to
expect using the bundled variant, which just seems to point to a
snapshot of the master branch and doesn't match any released libgit2
(bsc#1154817). See: https://github.com/rust-lang/rust/issues/63476 and
https://github.com/rust-lang/git2-rs/issues/458 for details.

Update to version 1.38.0

+ Language

- The `#[global_allocator]` attribute can now be used in submodules.
- The `#[deprecated]` attribute can now be used on macros.

+ Compiler

- Added pipelined compilation support to `rustc`. This will improve
compilation times in some cases.

+ Libraries

- `ascii::EscapeDefault` now implements `Clone` and `Display`.
- Derive macros for prelude traits (e.g. `Clone`, `Debug`, `Hash`) are
now available at the same path as the trait. (e.g. The `Clone` derive
macro is available at `std::clone::Clone`). This also makes all
built-in macros available in `std`/`core` root. e.g.
`std::include_bytes!`.
- `str::Chars` now implements `Debug`.
- `slice::{concat, connect, join}` now accepts `&[T]` in addition to
`&T`.
- `*const T` and `*mut T` now implement `marker::Unpin`.
- `Arc<[T]>` and `Rc<[T]>` now implement
`FromIterator<T>`.
- Added euclidean remainder and division operations (`div_euclid`,
`rem_euclid`) to all numeric primitives. Additionally `checked`,
`overflowing`, and `wrapping` versions are available for all integer
primitives.
- `thread::AccessError` now implements `Clone`, `Copy`, `Eq`, `Error`,
and `PartialEq`.
- `iter::{StepBy, Peekable, Take}` now implement `DoubleEndedIterator`.

+ Stabilized APIs

- `<*const T>::cast`
- `<*mut T>::cast`
- `Duration::as_secs_f32`
- `Duration::as_secs_f64`
- `Duration::div_f32`
- `Duration::div_f64`
- `Duration::from_secs_f32`
- `Duration::from_secs_f64`
- `Duration::mul_f32`
- `Duration::mul_f64`
- `any::type_name`

+ Cargo

- Added pipelined compilation support to `cargo`.
- You can now pass the `--features` option multiple times to enable
multiple features.

+ Misc

- `rustc` will now warn about some incorrect uses of
`mem::{uninitialized, zeroed}` that are known to cause undefined
behaviour.

Update to version 1.37.0

+ Language

- #[must_use] will now warn if the type is contained in a tuple, Box,
or an array and unused.
- You can now use the `cfg` and `cfg_attr` attributes on generic
parameters.
- You can now use enum variants through type alias. e.g. You can write
the following: ``` type MyOption = Option<u8>; fn
increment_or_zero(x: MyOption) -> u8 { match x { MyOption::Some(y)
=> y + 1, MyOption::None => 0, } } ```
- You can now use `_` as an identifier for consts. e.g. You can write
`const _: u32 = 5;`.
- You can now use `#[repr(align(X)]` on enums.
- The `?` Kleene macro operator is now available in the 2015 edition.

+ Compiler

- You can now enable Profile-Guided Optimization with the `-C
profile-generate` and `-C profile-use` flags. For more information
on how to use profile guided optimization, please refer to the rustc
book.
- The `rust-lldb` wrapper script should now work again.

+ Libraries

- `mem::MaybeUninit<T>` is now ABI-compatible with `T`.

+ Stabilized APIs

- BufReader::buffer
- BufWriter::buffer
- Cell::from_mut
- Cell<[T]>::as_slice_of_cells
- Cell<slice>::as_slice_of_cells

- u128::reverse_bits
- u16::reverse_bits
- u32::reverse_bits
- u64::reverse_bits
- u8::reverse_bits
- usize::reverse_bits

+ Cargo

- Cargo.lock files are now included by default when publishing
executable crates with executables.
- You can now specify `default-run="foo"` in `[package]` to
specify
the default executable to use for `cargo run`.
- cargo-vendor is now provided as a sub-command of cargo

+ Compatibility Notes

- Using `...` for inclusive range patterns will now warn by default.
Please transition your code to using the `..=` syntax for inclusive
ranges instead.
- Using a trait object without the `dyn` will now warn by default.
Please transition your code to use `dyn Trait` for trait objects
instead. Crab(String), Lobster(String), Person(String), let state =
Creature::Crab("Ferris"); if let Creature::Crab(name) |
Creature::Person(name) = state { println!("This creature's
name is:
{}", name); } unsafe { foo() } pub fn new(x: i32, y: i32) ->
Self {
Self(x, y) } pub fn is_origin(&self) -> bool { match self {
Self(0,
0) => true, _ => false, } } Self: PartialOrd<Self> // can
write
`Self` instead of `List<T>` Nil, Cons(T, Box<Self>) //
likewise here
fn test(&self) { println!("one"); } //~ ERROR duplicate
definitions
with name `test` fn test(&self) { println!("two"); }

* Basic procedural macros allowing custom `#[derive]`, aka "macros
1.1",
are stable. This allows popular code-generating crates like Serde and
Diesel to work ergonomically. [RFC 1681].
* [Tuple structs may be empty. Unary and empty tuple structs may be
instantiated with curly braces][36868]. Part of [RFC 1506].
* [A number of minor changes to name resolution have been
activated][37127]. They add up to more consistent semantics, allowing
for future evolution of Rust macros. Specified in [RFC 1560], see its
section on ["changes"] for details of what is different. The
breaking
changes here have been transitioned through the [`legacy_imports`] lint
since 1.14, with no known regressions.
* [In `macro_rules`, `path` fragments can now be parsed as type parameter
bounds][38279]
* [`?Sized` can be used in `where` clauses][37791]
* [There is now a limit on the size of monomorphized types and it can be
modified with the `#![type_size_limit]` crate attribute, similarly to
the `#![recursion_limit]` attribute][37789]
* [On Windows, the compiler will apply dllimport attributes when linking
to extern functions][37973]. Additional attributes and flags can control
which library kind is linked and its name. [RFC 1717].
* [Rust-ABI symbols are no longer exported from cdylibs][38117]
* [The `--test` flag works with procedural macro crates][38107]
* [Fix `extern "aapcs" fn` ABI][37814]
* [The `-C no-stack-check` flag is deprecated][37636]. It does nothing.
* [The `format!` expander recognizes incorrect `printf` and shell-style
formatting directives and suggests the correct format][37613].
* [Only report one error for all unused imports in an import list][37456]
* [Avoid unnecessary `mk_ty` calls in `Ty::super_fold_with`][37705]
* [Avoid more unnecessary `mk_ty` calls in `Ty::super_fold_with`][37979]
* [Don't clone in `UnificationTable::probe`][37848]
* [Remove `scope_auxiliary` to cut RSS by 10%][37764]
* [Use small vectors in type walker][37760]
* [Macro expansion performance was improved][37701]
* [Change `HirVec<P<T>>` to `HirVec<T>` in
`hir::Expr`][37642]
* [Replace FNV with a faster hash function][37229]
