build-std compatible sanitizer support by tmiasko · Pull Request #65241 · rust-lang/rust

tmiasko · 2019-10-09T16:55:35Z

Motivation

When using -Z sanitizer=* feature it is essential that both user code and
standard library is instrumented. Otherwise the utility of sanitizer will be
limited, or its use will be impractical like in the case of memory sanitizer.

The recently introduced cargo feature build-std makes it possible to rebuild
standard library with arbitrary rustc flags. Unfortunately, those changes alone
do not make it easy to rebuild standard library with sanitizers, since runtimes
are dependencies of std that have to be build in specific environment,
generally not available outside rustbuild process. Additionally rebuilding them
requires presence of llvm-config and compiler-rt sources.

The goal of changes proposed here is to make it possible to avoid rebuilding
sanitizer runtimes when rebuilding the std, thus making it possible to
instrument standard library for use with sanitizer with simple, although
verbose command:

env CARGO_TARGET_X86_64_UNKNOWN_LINUX_GNU_RUSTFLAGS=-Zsanitizer=thread cargo test -Zbuild-std --target x86_64-unknown-linux-gnu

Implementation

Sanitizer runtimes are no long packed into crates. Instead, libraries build
from compiler-rt are used as is, after renaming them into librusc_rt.*.
rustc obtains runtimes from target libdir for default sysroot, so that
they are not required in custom build sysroots created with build-std.
The runtimes are only linked-in into executables to address issue Rust should not link sanitizer runtimes unconditionally #64629.
(in previous design it was hard to avoid linking runtimes into static
libraries produced by rustc as demonstrated by sanitizer-staticlib-link
test, which still passes despite changes made in Only add sanitizer runtimes when linking an executable (#64629). #64780).

Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @nikomatsakis (or someone else) soon.

If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes.

Please see the contribution instructions for more information.

I have OSX but I'm not sure what a suitable test plan or steps would be here?

Otherwise I think everything reads pretty reasonably, but I'd want other better people to put their input into the matter :)

tmiasko · 2019-10-10T06:42:08Z

The src/test/run-make-fulldeps contains basic sanitizer tests.
I would suggest starting with those. Some of them are gated to be run
on Linux only, so I would check if this is still required.
Following that, I would create a small cargo project with tests that include
issues that should be reported by given sanitizer, and then test it with
-Zsanitize=*, and then again with -Zsanitize=* and -Zbuild-std.
Repeat above for some real world project. For a thread sanitizer, test
suites & benchmarks from crossbeam or tokio crates would be great. I would
expect to get reports from either of those, so it should be clear if things
are working on not.

Concrete steps for step 3 suitable for x86_64-unknown-linux-gnu:

~/rust $ ./x.py build --stage 1
~/rust $ mkdir -p build/x86_64-unknown-linux-gnu/stage1/lib/rustlib/src
~/rust $ ln -sT $PWD build/x86_64-unknown-linux-gnu/stage1/lib/rustlib/src/rust
~/rust $ rustup toolchain link stage1 build/x86_64-unknown-linux-gnu/stage1

# Testing on tokio: 
~/tokio $ cargo clean
~/tokio $ env CARGO_TARGET_X86_64_UNKNOWN_LINUX_GNU_RUSTFLAGS=-Zsanitizer=thread cargo +stage1 test --target x86_64-unknown-linux-gnu
~/tokio $ cargo clean
~/tokio $ env CARGO_TARGET_X86_64_UNKNOWN_LINUX_GNU_RUSTFLAGS=-Zsanitizer=thread cargo +stage1 -Zbuild-std test --target x86_64-unknown-linux-gnu

nikomatsakis · 2019-10-10T13:19:31Z

Is there any documentation for how sanitizers work today? I think that before we make any major changes to the setup, I'd like to see that rectified, so that the new design can be described as an update to the documentation. The rustc-guide would be a suitable place for such a thing. We could also hold a design meeting, but I don't think that's necessarily required, since sanitizers are still experimental.

Firstyear · 2019-10-11T00:52:56Z

Honestly, because they are a -Z flag, and thus nightly only, I think that documentation has not emerged because people don't know they exist, can't access them when they need stable, or have developed other work arounds. For example, I'm required to setup RUSTC_BOOTSTRAP=1 in my makefiles to use stable compilers + -Z with sanitizers and FFI.

I also think that because their major value is with FFI, and that requires the C components to always work with sanitizers, there are not many projects currently using them broadly.

So this all led to the sanitizers being a super niche feature, wildly useful for people like me who has a C code base that is sanitized and able to develop the tricks to use them with Rust FFI, but most people don't have that set of overlapping scenarios to bring this into peoples minds.

I think that if the first line of the documentation was "you need nightly to use sanitizers" that's already a major barrier to getting this used more broadly. So I think we need to seriously discuss how we get features like this out from behind nightly only.

tmiasko · 2019-10-14T22:27:10Z

@nikomatsakis japaric published user oriented documentation at https://github.com/japaric/rust-san.

Substantial part of it is dedicated to answering the question how to rebuild
and instrument the std, and how to ignore false positives generated when
previous step wasn't followed. Those parts should now be unnecessary thanks to
-Zbuild-std in cargo and changes proposed here.

I don't think there was any documentation for implementation in rustc, apart
from description on the pull requests and as a part of discussions therein.

Related documentation changes in rustc-guide rust-lang/rustc-dev-guide#466.

choller · 2019-10-15T16:39:18Z

Thanks for working on this. After some discussions in Discord it seems that this PR is the right way to move forward. As you have noticed, my fix for #64629 was not comprehensive. I am still facing issues where sanitizer runtimes are linked to libraries and we still cannot build Firefox with TSan for that reason.

nikomatsakis · 2019-10-15T17:59:49Z

@tmiasko first off, thanks a ton for the rustc-guide PR! As I wrote in my review, I suspect that the 'how to use sanitizer' material would be better off in the src/doc/rustc directory, as part of the "rustc book". Do you think you could leave a few notes in the rustc-guide describing how sanitizer integration works? (like, it seems like we have to link some LLVM libraries somewhere, and we are copying some files around, why are we doing that?)

My motivation here is that, particularly for these "little used, perenially unstable" features, I'd like to have some notes on how things work so that if we have to fix bugs we have some idea where to start. (Although this sparks an idea for me that maybe, for features like these, we should also have people kind of "sign up" as maintainers that can be pinged if problems arise... right now, we don't have any notion of who those people might be. I presume you'd be up for that?)

To be clear: if there were some docs on how -Zsanitizer is used (like the ones you already wrote) and how it is implemented (I think those don't quite exist yet), I'd be very happy to r+ the PR. Also, to be clear: I realize I'm asking you to do a bit more than we sometimes do -- I'm just trying to bootstrap an effort to get rustc better documented, one PR at a time. Nothing personal. :)

ehuss · 2019-10-16T15:07:03Z

I just wanted to note that adding unstable documentation to the rustc book is a little unusual, as it doesn't contain any unstable docs right now. Normally the unstable documentation goes in the Unstable Book. I personally don't care too much in this case, but thought I would point it out.

EDIT: It may want to at least mention that the chapter is about an unstable feature.

src/doc/rustc/src/sanitizers.md

tmiasko · 2019-10-16T15:49:50Z

@ehuss thanks for suggestion, the unstable-book seems more appropriate. The
-Zsanitizer feature itself is unstable, moreover I think it is best
combined with -Zbuild-std which is also unstable.

I moved the user oriented parts to unstable-book (new commit here). The
high-level overview of the implementation was left in rustc-guide with
additional details about building runtimes, copying, and linking them.

@nikomatsakis sure, you cc me on issues related to sanitizers.

nikomatsakis · 2019-10-18T11:05:03Z

@ehuss

I just wanted to note that adding unstable documentation to the rustc book is a little unusual, as it doesn't contain any unstable docs right now

Hmm, I'm ok with the unstable book too. I tend to think that means nobody will ever find it there, but maybe that's the point.

nikomatsakis · 2019-10-18T11:06:41Z

To elaborate on my previous comment, by "maybe that's the point" I meant:

we don't want people to come across unstable content too easily
and if they ask questions, we can point them at the right place

That said, maybe it'd be useful to extend the rustc book with a pointer to the unstable guide to say something like "you can find documentation on unstable options here". I do appreciate the idea of making it extra clear when things are unstable. The same could apply to the self-profile options.

nikomatsakis · 2019-10-18T11:15:40Z

I'm quite satisfied. Thanks again @tmiasko for going to the extra mile to document what's going on, it made reading the PR much easier.
