* Enable clap's `wrap_help` feature by default
This is similar to bytecodealliance/wasm-tools#1746 which makes the help
text easier to read on various terminal widths.
* Fix `cargo deny`
* Remove deny.toml exception for wasm-coredump-builder
This isn't used any more so no need to continue to list this.
* Update Wasmtime's pretty_env_logger dependency
This removes a `deny.toml` exception for that crate, but `openvino-sys`
still depends on `pretty_env_logger 0.4.0` so a new exception is added
for that.
* Update criterion and clap dependencies
This commit started out by updating the `criterion` dependency to remove
an entry in `deny.toml`, but that ended up transitively requiring a
`clap` dependency upgrade from 3.x to 4.x because `criterion` uses
pieces of clap 4.x. Most of this commit is then dedicated to updating
clap 3.x to 4.x which was relatively simple, mostly renaming attributes
here and there.
* Update gimli-related dependencies
I originally wanted to remove the `indexmap` clause in `deny.toml` but
enough dependencies haven't updated from 1.9 to 2.0 that it wasn't
possible. In the meantime though this updates some various dependencies
to bring them to the latest and a few of them now use `indexmap` 2.0.
* Update deps to remove `windows-sys 0.45.0`
This involved updating tokio/mio and then providing new audits for new
crates. The tokio exemption was updated from its old version to the new
version and tokio remains un-audited.
* Update `syn` to 2.x.x
This required a bit of rewriting for the component-macro related bits
but otherwise was pretty straightforward. The `syn` 1.x.x track is still
present in the wasi-crypto tree at this time.
I've additionally added some trusted audits for my own publications of
`wasm-bindgen`
* Update bitflags to 2.x.x
This updates Wasmtime's dependency on the `bitflags` crate to the 2.x.x
track to keep it up-to-date.
* Update the cap-std family of crates
This bumps them all to the next major version to keep up with updates.
I've additionally added trusted entries for publishes of cap-std crates
from Dan.
There's still lingering references to rustix 0.37.x which will need to
get weeded out over time.
* Update memoffset dependency to latest
Avoids having two versions in our crate graph.
* Fix tests
* Update try_from for wiggle flags
* Fix build on AArch64 Linux
* Enable `event` for rustix on Windows too
* wasi-tests and wasi-http-tests no longer have their own workspace
* wasi-tests: fix warnings
* rewrite the test-programs build.rs to generate {package}_modules.rs and _components.rs
The style is cribbed from preview2-prototying repo, but I ended up
refactoring it a bit.
* better escaping should help with windows?
* long form cap-std-sync and tokio test suites
* convert wasi-http test
* fixes, comments
* apply cargo fmt to whole workspace
* bump test-programs and wasi-http-tests to all use common dependency versions
wit-bindgen 0.6.0 and wit-component 0.7.4
* add new audits
* cargo vet prune
* package and supply chain updates to fix vulnerabilities
h2 upgraded from 0.3.16 -> 0.3.19 to fix vulnerability
tempfile upgraded from 0.3.3 -> 0.3.5 to eliminate dep on vulnerable
remove_dir_all
* deny: temporarily allow duplicate wasm-encoder, wasmparser, wit-parser
prtest:full
* convert more dependencies to { workspace = true }
Alex asked me to do thsi for wit-component and wit-bindgen, and I found
a few more (cfg-if, tempfile, filecheck, anyhow...
I also reorganized the workspace dependencies section to make the ones
our team maintains more clearly separated from our external
dependencies.
* test-programs build: ensure that the user writes a #[test] for each module, component
* fix build of wasi-tests on windows
* misspelled macos
* mark wasi-tests crate test=false so we dont try building it natively...
* mark wasi-http-tests test=false as well
* try getting the cargo keys right
* just exclude wasi-tests and wasi-http-tests in run-tests.sh
* interesting paths fails on windows
* misspelling so nice i did it twice
* new cargo deny exception: ignore all of wit-bindgen's dependencies
* auto-import wildcard vets
* Update to latest wasm-tools crates
This commit pushes through the full update of the wasm-tools crates
through Wasmtime. There are two major features which changed, both
related to components, which required updates in Wasmtime:
* Resource types are now implemented in wasm-tools and they're not yet
implemented in Wasmtime so I've stubbed out the integration point with
panics as reminders to come back and implement them.
* There are new validation rules about how aggregate types must be
named. This doesn't affect runtime internals at all but was done on
behalf of code generators. This did however affect a number of tests
which have to ensure that types are exported.
* Fix more tests
* Add vet entries
* Update coredump generation in the cli to use wasm_encoder
* Add deny.toml exception for wasm-encoder 0.25.0
* add missing newline
* update custom section in fuzzing crate
This updates to rustix 0.37.13, which contains some features we can use to
implement more features in wasi-common for the wasi-sockets API. This also
pulls in several other updates to avoid having multiple versions of rustix.
This does introduce multiple versions of windows-sys, as the errno and tokio
crates are currently using 0.45 while rustix and other dependencies have
updated to 0.48; PRs updating these are already in flight so this will
hopefully be resolved soon.
It also includes cap-std 1.0.14, which disables the use of `openat2` and
`statx` on Android, fixing a bug where some Android devices crash the
process when those syscalls are executed.
* add cargo-deny exception for duplicate versions of windows-sys
* cargo vetting for all new deps introduced by https://github.com/bytecodealliance/wasmtime/pull/5929
The audits are straightforward. The exemptions, as always, need to be justified:
* core-foundation, core-foundation-sys, security-framework, security-framework-sys: these are large crates which are FFI bindings to Mac OS frameworks. As such they contain tons of unsafe code to make these FFI calls and manage memory. These crates are too big to audit.
* schannel: same as the above, except this is a windows component, which I'm also unfamiliar with.
* openssl, openssl-sys: also large FFI bindings which are impractical to audit.
* futures-macro, futures-task: while not as complex as futures-util, these are beyond my personal understanding of futures to vet practically. I've asked Alex to look at auditing these, and he will after he returns from vacation next week.
* futures-util: 25kloc of code, over 149 instances of the substring "unsafe" (case insensitive), this is impractical to audit in the extreme.
* h2, http, httparse, hyper, mio, tokio: this so-called tokio/hyper family are very large and challenging to audit. Bobby Holley has indicated that he is working to get the AWS engineers who maintain these crates to publish their own audits, which we can then import. We expect to exempt these until those imports are available.
This notably updates `wasmparser` for updates to the relaxed-simd
proposal and an implementation of the function-references proposal.
Additionally there are some minor bug fixes being picked up for WIT and
the component model.
* Implement strings in adapter modules
This commit is a hefty addition to Wasmtime's support for the component
model. This implements the final remaining type (in the current type
hierarchy) unimplemented in adapter module trampolines: strings. Strings
are the most complicated type to implement in adapter trampolines
because they are highly structured chunks of data in memory (according
to specific encodings). Additionally each lift/lower operation can
choose its own encoding for strings meaning that Wasmtime, the host, may
have to convert between any pairwise ordering of string encodings.
The `CanonicalABI.md` in the component-model repo in general specifies
all the fiddly bits of string encoding so there's not a ton of wiggle
room for Wasmtime to get creative. This PR largely "just" implements
that. The high-level architecture of this implementation is:
* Fused adapters are first identified to determine src/dst string
encodings. This statically fixes what transcoding operation is being
performed.
* The generated adapter will be responsible for managing calls to
`realloc` and performing bounds checks. The adapter itself does not
perform memory copies or validation of string contents, however.
Instead each transcoding operation is modeled as an imported function
into the adapter module. This means that the adapter module
dynamically, during compile time, determines what string transcoders
are needed. Note that an imported transcoder is not only parameterized
over the transcoding operation but additionally which memory is the
source and which is the destination.
* The imported core wasm functions are modeled as a new
`CoreDef::Transcoder` structure. These transcoders end up being small
Cranelift-compiled trampolines. The Cranelift-compiled trampoline will
load the actual base pointer of memory and add it to the relative
pointers passed as function arguments. This trampoline then calls a
transcoder "libcall" which enters Rust-defined functions for actual
transcoding operations.
* Each possible transcoding operation is implemented in Rust with a
unique name and a unique signature depending on the needs of the
transcoder. I've tried to document inline what each transcoder does.
This means that the `Module::translate_string` in adapter modules is by
far the largest translation method. The main reason for this is due to
the management around calling the imported transcoder functions in the
face of validating string pointer/lengths and performing the dance of
`realloc`-vs-transcode at the right time. I've tried to ensure that each
individual case in transcoding is documented well enough to understand
what's going on as well.
Additionally in this PR is a full implementation in the host for the
`latin1+utf16` encoding which means that both lifting and lowering host
strings now works with this encoding.
Currently the implementation of each transcoder function is likely far
from optimal. Where possible I've leaned on the standard library itself
and for latin1-related things I'm leaning on the `encoding_rs` crate. I
initially tried to implement everything with `encoding_rs` but was
unable to uniformly do so easily. For now I settled on trying to get a
known-correct (even in the face of endianness) implementation for all of
these transcoders. If an when performance becomes an issue it should be
possible to implement more optimized versions of each of these
transcoding operations.
Testing this commit has been somewhat difficult and my general plan,
like with the `(list T)` type, is to rely heavily on fuzzing to cover
the various cases here. In this PR though I've added a simple test that
pushes some statically known strings through all the pairs of encodings
between source and destination. I've attempted to pick "interesting"
strings that one way or another stress the various paths in each
transcoding operation to ideally get full branch coverage there.
Additionally a suite of "negative" tests have also been added to ensure
that validity of encoding is actually checked.
* Fix a temporarily commented out case
* Fix wasmtime-runtime tests
* Update deny.toml configuration
* Add `BSD-3-Clause` for the `encoding_rs` crate
* Remove some unused licenses
* Add an exemption for `encoding_rs` for now
* Split up the `translate_string` method
Move out all the closures and package up captured state into smaller
lists of arguments.
* Test out-of-bounds for zero-length strings
Previously, `listenfd` depended on an old version of the `uuid` crate
which caused cargo deny failures.
https://github.com/mitsuhiko/listenfd/pull/13 upgrades the `uuid`
dependency and a new version of `listenfd` is published. This change
moves to the latest version of `listenfd`.
As discussed previously, we need a way to be able to configure Wasmtime when running it in the Sightglass benchmark infrastructure. The easiest way to do this seemed to be to pass a string from Sightglass to the `bench-api` library and parse this in the same way that Wasmtime parses its CLI flags. The structure that contains these flags is `CommonOptions`, so it has been moved to its own crate to be depended on by both `wasmtime-cli` and `wasmtime-bench-api`. Also, this change adds an externally-visible function for parsing a string into `CommonOptions`, which is used for configuring an engine.
* Update to clap 3.0
This commit migrates all CLI commands internally used in this project
from structopt/clap2 to clap 3. The intent here is to ensure that we're
using maintained versions of the dependencies as structopt and clap 2
are less maintained nowadays. Most transitions were pretty
straightforward and mostly dealing with structopt/clap3 differences.
* Fix a number of `cargo deny` errors
This commit fixes a few errors around duplicate dependencies which
arose from the prior update to clap3. This also uses a new feature in
`deny.toml`, `skip-tree`, which allows having a bit more targeted
ignores for skips of duplicate version checks. This showed a few more
locations in Wasmtime itself where we could update some dependencies.
* 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.
Before this commit we actually have two builders checking for security
advisories on CI, one is `cargo audit` and one is `cargo deny`. The
`cargo deny` builder is slightly different in that it checks a few other
things about our dependency tree such as licenses, duplicates, etc. This
commit removes the advisory check from `cargo deny` on CI and then moves
the `cargo audit` check to a separate workflow.
The `cargo audit` check will now run nightly and will open an issue on
the Wasmtime repository when an advisory is found. This should help make
it such that our CI is never broken by the publication of an advisory
but we're still promptly notified whenever an advisory is made. I've
updated the release process notes to indicate that the open issues
should be double-checked to ensure that there are no open advisories
that we need to take care of.
On the build side, this commit introduces two things:
1. The automatic generation of various ISLE definitions for working with
CLIF. Specifically, it generates extern type definitions for clif opcodes and
the clif instruction data `enum`, as well as extractors for matching each clif
instructions. This happens inside the `cranelift-codegen-meta` crate.
2. The compilation of ISLE DSL sources to Rust code, that can be included in the
main `cranelift-codegen` compilation.
Next, this commit introduces the integration glue code required to get
ISLE-generated Rust code hooked up in clif-to-x64 lowering. When lowering a clif
instruction, we first try to use the ISLE code path. If it succeeds, then we are
done lowering this instruction. If it fails, then we proceed along the existing
hand-written code path for lowering.
Finally, this commit ports many lowering rules over from hand-written,
open-coded Rust to ISLE.
In the process of supporting ISLE, this commit also makes the x64 `Inst` capable
of expressing SSA by supporting 3-operand forms for all of the existing
instructions that only have a 2-operand form encoding:
dst = src1 op src2
Rather than only the typical x86-64 2-operand form:
dst = dst op src
This allows `MachInst` to be in SSA form, since `dst` and `src1` are
disentangled.
("3-operand" and "2-operand" are a little bit of a misnomer since not all
operations are binary operations, but we do the same thing for, e.g., unary
operations by disentangling the sole operand from the result.)
There are two motivations for this change:
1. To allow ISLE lowering code to have value-equivalence semantics. We want ISLE
lowering to translate a CLIF expression that evaluates to some value into a
`MachInst` expression that evaluates to the same value. We want both the
lowering itself and the resulting `MachInst` to be pure and referentially
transparent. This is both a nice paradigm for compiler writers that are
authoring and maintaining lowering rules and is a prerequisite to any sort of
formal verification of our lowering rules in the future.
2. Better align `MachInst` with `regalloc2`'s API, which requires that the input
be in SSA form.
Previously the inclusion of the `criterion` crate had brought in a
transitive dependency to `cast`, which used old versions of several
libraries. Now that https://github.com/japaric/cast.rs/pull/26 is merged
and a new version published, we can update `cast` and remove the
cargo-deny rules for the duplicated, older versions.
Until https://github.com/japaric/cast.rs/pull/26 is resolved, the `cast`
crate will pull in older versions of the `rustc_version`, `semver`, and
`semver-parser` crates. `cast` is a build dependency of `criterion`
which is used for benchmarking and is itself a dev dependency, not a
normal dependency.
Transient dependencies depend on two different versions of `cpuid-bool`.
This advisory does not appear to be urgent. We should review this ignore
after a few weeks to see if our deps have switched over.

* wasi-nn: turn it on by default
This change makes the wasi-nn Cargo feature a default feature. Previously, a wasi-nn user would have to build a separate Wasmtime binary (e.g. `cargo build --features wasi-nn ...`) to use wasi-nn and the resulting binary would require OpenVINO shared libraries to be present in the environment in order to run (otherwise it would fail immediately with linking errors). With recent changes to the `openvino` crate, the wasi-nn implementation can defer the loading of the OpenVINO shared libraries until runtime (i.e., when the user Wasm program calls `wasi_ephemeral_nn::load`) and display a user-level error if anything goes wrong (e.g., the OpenVINO libraries are not present on the system). This runtime-linking addition allows the wasi-nn feature to be turned on by default and shipped with upcoming releases of Wasmtime. This change should be transparent for users who do not use wasi-nn: the `openvino` crate is small and the newly-available wasi-nn imports only affect programs in which they are used.
For those interested in reviewing the runtime linking approach added to the `openvino` crate, see https://github.com/intel/openvino-rs/pull/19.
* wasi-nn spec path: don't use canonicalize
* Allow dependencies using the ISC license
The ISC license should be [just as permissive](https://choosealicense.com/licenses/isc) as MIT, e.g., with no additional limitations.
* Add a `--wasi-modules` flag
This flag controls which WASI modules are made available to the Wasm program. This initial commit enables `wasi-common` by default (equivalent to `--wasi-modules=all`) and allows `wasi-nn` and `wasi-crypto` to be added in either individually (e.g., `--wasi-modules=wasi-nn`) or as a group (e.g., `--wasi-modules=all-experimental`).
* wasi-crypto: fix unused dependency

This commit goes through the dependencies that wasmtime has and updates
versions where possible. This notably brings in a wasmparser/wast update
which has some simd spec changes with new instructions. Otherwise most
of these are just routine updates.
