* add a wasi-test to show a dir_fd always gets ERRNO_BADF on appropriate fd_ operations.
This is a conformance test for the current behavior of preview 1 in wasi-common. It is debatable whether this is the right errno, I think for most of these ERRNO_ISDIR would be more descriptive, but this is the behavior we have.
* Add comments to all the fd op failures explaining closest linux/posix behavior
Wasmtime disallows guests from using `path_symlink` to create
absolute-path symlinks, as they could confuse other code into
accessing resources on the host that the guest otherwise doesn't
have access to.
This patch adds a test for this behavior.

Early on in WASI, we weren't sure whether we should allow preopens to be
closed, so conservatively, we disallowed them. Among other things, this
protected assumptions in wasi-libc that it can hold onto preopen file
descriptors and rely on them always being open.
However now, I think it makes sense to relax this restriction. wasi-libc
itself doesn't expose the preopen file descriptors, so users shouldn't
ever be closing them naively, unless they have wild closes. And
toolchains other than wasi-libc may want to close preopens as a way to
drop priveleges once the main file handles are opened.
This updates the tests to version 0.11 of the wasi bindings. There
aren't any fundamental changes here; this just syncs up with the latest
version so that it's consistent with other users of the wasi APIs.
* Add release notes for 3.0.1
* Update some version directives for crates in Wasmtime
* Mark anything with `publish = false` as version 0.0.0
* Mark the icache coherence crate with the same version as Wasmtime
* Fix manifest directives
* Remove explicit `S` type parameters
This commit removes the explicit `S` type parameter on `Func::typed` and
`Instance::get_typed_func`. Historical versions of Rust required that
this be a type parameter but recent rustcs support a mixture of explicit
type parameters and `impl Trait`. This removes, at callsites, a
superfluous `, _` argument which otherwise never needs specification.
* Fix mdbook examples
* Leverage Cargo's workspace inheritance feature
This commit is an attempt to reduce the complexity of the Cargo
manifests in this repository with Cargo's workspace-inheritance feature
becoming stable in Rust 1.64.0. This feature allows specifying fields in
the root workspace `Cargo.toml` which are then reused throughout the
workspace. For example this PR shares definitions such as:
* All of the Wasmtime-family of crates now use `version.workspace =
true` to have a single location which defines the version number.
* All crates use `edition.workspace = true` to have one default edition
for the entire workspace.
* Common dependencies are listed in `[workspace.dependencies]` to avoid
typing the same version number in a lot of different places (e.g. the
`wasmparser = "0.89.0"` is now in just one spot.
Currently the workspace-inheritance feature doesn't allow having two
different versions to inherit, so all of the Cranelift-family of crates
still manually specify their version. The inter-crate dependencies,
however, are shared amongst the root workspace.
This feature can be seen as a method of "preprocessing" of sorts for
Cargo manifests. This will help us develop Wasmtime but shouldn't have
any actual impact on the published artifacts -- everything's dependency
lists are still the same.
* Fix wasi-crypto tests
`tracing` crate is already used within the codebase, this change allows
developers to benefit from that functionality when running and debugging
tests

* Update to cap-std 0.26.
This is primarily to pull in bytecodealliance/cap-std#271, the fix for #4936,
compilation on Rust nightly on Windows.
It also updates to rustix 0.35.10, to pull in bytecodealliance/rustix#403,
the fix for bytecodealliance/rustix#402, compilation on newer versions of
the libc crate, which changed a public function from `unsafe` to safe.
Fixes#4936.
* Update the system-interface audit for 0.23.
* Update the libc supply-chain config version.
* Optimize the WASI `random_get` implementation.
Use `StdRng` instead of the `OsRng` in the default implementation of
`random_get`. This uses a userspace CSPRNG, making `random_get` 3x faster
in simple benchmarks.
* Update cargo-vet audits for cap-std 0.25.3.
* Update all cap-std packages to 0.25.3.
This commit replaces #4869 and represents the actual version bump that
should have happened had I remembered to bump the in-tree version of
Wasmtime to 1.0.0 prior to the branch-cut date. Alas!
* Stop returning `NOTCAPABLE` errors from WASI calls.
`ENOTCAPABLE` was an error code that is used as part of the rights
system, from CloudABI. There is a set of flags associated with each file
descriptor listing which operations can be performed with the file
descriptor, and if an attempt is made to perform an operation with a
file descriptor that isn't permitted by its rights flags, it fails with
`ENOTCAPABLE`.
WASI is removing the rights system. For example, WebAssembly/wasi-libc#294
removed support for translating `ENOTCAPABLE` into POSIX error codes, on
the assumption that engines should stop using it.
So as another step to migrating away from the rights system, remove uses
of the `ENOTCAPABLE` error.

This commit builds on bytecodealliance/wasm-tools#690 to add support to
testing of the component model to execute functions when running
`*.wast` files. This support is all built on #4442 as functions are
invoked through a "dynamic" API. Right now the testing and integration
is fairly crude but I'm hoping that we can try to improve it over time
as necessary. For now this should provide a hopefully more convenient
syntax for unit tests and the like.
* Don't try to report file size or timestamps for stdio streams.
Calling `File::metadata()` on a stdio stream handle fails on Windows, where
the stdio streams are not files.
This `File::metadata()` call was effectively only being used to add file size
and timestamps to the result of `filestat_get`. It's common for users to
redirect stdio streams to interesting places, and applications
generally shouldn't change their behavior depending on the size or
timestamps of the file, if the streams are redirected to a file, so just
leave these fields to 0, which is commonly understood to represent
"unknown".
Fixes#4497.
* Remove dependency on `more-asserts`
In my recent adventures to do a bit of gardening on our dependencies I
noticed that there's a new major version for the `more-asserts` crate.
Instead of updating to this though I've opted to instead remove the
dependency since I don't think we heavily lean on this crate and
otherwise one-off prints are probably sufficient to avoid the need for
pulling in a whole crate for this.
* Remove exemption for `more-asserts`
* Bump versions of wasm-tools crates
Note that this leaves new features in the component model, outer type
aliases for core wasm types, unimplemented for now.
* Move to crates.io-based versions of tools
* Update tracing-core to a version which doesn't depend on lazy-static.
* Update crossbeam-utils to a version that doesn't depend on lazy-static.
* Update crossbeam-epoch to a version that doesn't depend on lazy-static.
* Update clap to a version that doesn't depend on lazy-static.
* Convert Wasmtime's own use of lazy_static to once_cell.
* Make `GDB_REGISTRATION`'s comment a doc comment.
* Fix compilation on Windows.
This updates to rustix 0.35.6, and updates wasi-common to use cap-std 0.25 and
windows-sys (instead of winapi).
Changes include:
- Better error code mappings on Windows.
- Fixes undefined references to `utimensat` on Darwin.
- Fixes undefined references to `preadv64` and `pwritev64` on Android.
- Updates to io-lifetimes 0.7, which matches the io_safety API in Rust.
- y2038 bug fixes for 32-bit platforms
* Update wasm-tools crates
This commit updates the wasm-tools family of crates as used in Wasmtime.
Notably this brings in the update which removes module linking support
as well as a number of internal refactorings around names and such
within wasmparser itself. This updates all of the wasm translation
support which binds to wasmparser as appropriate.
Other crates all had API-compatible changes for at least what Wasmtime
used so no further changes were necessary beyond updating version
requirements.
* Update a test expectation
* Upgrade all crates to the Rust 2021 edition
I've personally started using the new format strings for things like
`panic!("some message {foo}")` or similar and have been upgrading crates
on a case-by-case basis, but I think it probably makes more sense to go
ahead and blanket upgrade everything so 2021 features are always
available.
* Fix compile of the C API
* Fix a warning
* Fix another warning
* Bump to 0.36.0
* Add a two-week delay to Wasmtime's release process
This commit is a proposal to update Wasmtime's release process with a
two-week delay from branching a release until it's actually officially
released. We've had two issues lately that came up which led to this proposal:
* In #3915 it was realized that changes just before the 0.35.0 release
weren't enough for an embedding use case, but the PR didn't meet the
expectations for a full patch release.
* At Fastly we were about to start rolling out a new version of Wasmtime
when over the weekend the fuzz bug #3951 was found. This led to the
desire internally to have a "must have been fuzzed for this long"
period of time for Wasmtime changes which we felt were better
reflected in the release process itself rather than something about
Fastly's own integration with Wasmtime.
This commit updates the automation for releases to unconditionally
create a `release-X.Y.Z` branch on the 5th of every month. The actual
release from this branch is then performed on the 20th of every month,
roughly two weeks later. This should provide a period of time to ensure
that all changes in a release are fuzzed for at least two weeks and
avoid any further surprises. This should also help with any last-minute
changes made just before a release if they need tweaking since
backporting to a not-yet-released branch is much easier.
Overall there are some new properties about Wasmtime with this proposal
as well:
* The `main` branch will always have a section in `RELEASES.md` which is
listed as "Unreleased" for us to fill out.
* The `main` branch will always be a version ahead of the latest
release. For example it will be bump pre-emptively as part of the
release process on the 5th where if `release-2.0.0` was created then
the `main` branch will have 3.0.0 Wasmtime.
* Dates for major versions are automatically updated in the
`RELEASES.md` notes.
The associated documentation for our release process is updated and the
various scripts should all be updated now as well with this commit.
* Add notes on a security patch
* Clarify security fixes shouldn't be previewed early on CI
Other than doc updates, this just contains bytecodealliance/cap-std#235,
a fix for compilation errors on Rust nightly that look like this:
```
error[E0308]: mismatched types
--> cap-primitives/src/fs/via_parent/rename.rs:22:58
|
22 | let (old_dir, old_basename) = open_parent(old_start, &old_path)?;

```
Following up on #3696, use the new is-terminal crate to test for a tty
rather than having platform-specific logic in Wasmtime. The is-terminal
crate has a platform-independent API which takes a handle.
This also updates the tree to cap-std 0.24 etc., to avoid depending on
multiple versions of io-lifetimes at once, as enforced by the cargo deny
check.
* Update to cap-std 0.22.0.
The main change relevant to Wasmtime here is that this includes the
rustix fix for compilation errors on Rust nightly with the `asm!` macro.
* Add itoa to deny.toml.
* Update the doc and fuzz builds to the latest Rust nightly.
* Update to libc 0.2.112 to pick up the `POLLRDHUP` fix.
* Update to cargo-fuzz 0.11, for compatibility with Rust nightly.
This appears to be the fix for rust-fuzz/cargo-fuzz#277.
This pulls in a fix for Android, where Android's seccomp policy on older
versions is to make `openat2` irrecoverably crash the process, so we have
to do a version check up front rather than relying on `ENOSYS` to
determine if `openat2` is supported.
And it pulls in the fix for the link errors when multiple versions of
rsix/rustix are linked in.
And it has updates for two crate renamings: rsix has been renamed to
rustix, and unsafe-io has been renamed to io-extras.
* Use rsix to make system calls in Wasmtime.
`rsix` is a system call wrapper crate that we use in `wasi-common`,
which can provide the following advantages in the rest of Wasmtime:
- It eliminates some `unsafe` blocks in Wasmtime's code. There's
still an `unsafe` block in the library, but this way, the `unsafe`
is factored out and clearly scoped.
- And, it makes error handling more consistent, factoring out code for
checking return values and `io::Error::last_os_error()`, and code that
does `errno::set_errno(0)`.
This doesn't cover *all* system calls; `rsix` doesn't implement
signal-handling APIs, and this doesn't cover calls made through `std` or
crates like `userfaultfd`, `rand`, and `region`.
Modify the `poll_oneoff_files` test to avoid assuming that `poll_oneoff`
returns all pending events, as it may sometimes return only a subset of
events. When multiple events are expected, use a loop, and loop until
all events have been recorded.
- Fixes for compiling on OpenBSD
- io-lifetimes 0.3.0 has an option (io_lifetimes_use_std, which is off
by default) for testing the `io_safety` feature in Rust nightly.
* Port wasi-common to io-lifetimes.
This ports wasi-common from unsafe-io to io-lifetimes.
Ambient authority is now indicated via calls to `ambient_authority()`
from the ambient-authority crate, rather than using `unsafe` blocks.
The `GetSetFdFlags::set_fd_flags` function is now split into two phases,
to simplify lifetimes in implementations which need to close and re-open
the underlying file.
* Use posish for errno values instead of libc.
This eliminates one of the few remaining direct libc dependencies.
* Port to posish::io::poll.
Use posish::io::poll instead of calling libc directly. This factors out
more code from Wasmtime, and eliminates the need to manipulate raw file
descriptors directly.
And, this eliminates the last remaining direct dependency on libc in
wasi-common.
* Port wasi-c-api to io-lifetimes.
* Update to posish 0.16.0.
* Embeded NULs in filenames now get `EINVAL` instead of `EILSEQ`.
* Accept either `EILSEQ` or `EINVAL` for embedded NULs.
* Bump the nightly toolchain to 2021-07-12.
This fixes build errors on the semver crate, which as of this writing
builds with latest nightly and stable but not 2021-04-11, the old pinned
version.
* Have cap-std-sync re-export ambient_authority so that users get the same version.
This increases the timeout from 50ms to 200ms, which makes the
tests reliably pass on my machine using the CI scripts againt
the s390x-linux-user qemu target.
