 [patch] tests: add missing cross disabled checks
MIME-Version: 1.0
Content-Type: text/plain; charset="utf-8"
Content-Transfer-Encoding: 8bit

cross_conmpile::alternate states it should only be used in test cases
after checking cross_compile::disabled(), which is missing here. these
tests fail despite setting CFG_DISABLE_CROSS_TESTS on i386, since both
the host and the alternate cross target would be i686 in that case.

need to remove some hunks from this patch after pruning dependencies, since
hopefully a few of the crates patched during early rebasing are eliminated.

the build and don't pull in windows-sys and friends.

 set dt_soname when building dylibs

In Rust, library filenames include a version-specific hash to help
the run-time linker find the correct version.  Unlike in C/C++, the
compiler looks for all libraries matching a glob that ignores the
hash and reads embedded metadata to work out versions, etc.

The upshot is that there is no need for the usual "libfoo.so ->
libfoo-1.2.3.so" symlink common with C/C++ when building with Rust,
and no need to communicate an alternate filename to use at run-time
vs compile time.  If linking to a Rust dylib from C/C++ however, a
"libfoo.so -> libfoo-$hash.so" symlink may well be useful and in
this case DT_SONAME=libfoo-$hash.so would be required.  More
mundanely, various tools (eg: dpkg-shlibdeps) complain if they don't
find DT_SONAME on shared libraries in public directories.

This patch passes -Wl,-soname=$outfile when building dylibs (and
using a GNU linker).

it cannot work since there are no bundled LLVM (and thus no bundled

fix feat!: detect SHA1 collision attacks

Fix [GHSA-2frx-2596-x5r6].

[GHSA-2frx-2596-x5r6]: https://github.com/GitoxideLabs/gitoxide/security/advisories/GHSA-2frx-2596-x5r6

This uses the `sha1-checked` crate from the RustCrypto project. Its
a pure Rust implementation, with no SIMD or assembly code.

The hashing implementation moves to `gix-hash`, as it no longer
depends on any feature configuration. I wasnt sure the ideal
crate to put this in, but after checking reverse dependencies on
crates.io, it seems like theres essentially no user of `gix-hash`
that wouldnt be pulling in a hashing implementation anyway, so I
think this is a fine and logical place for it to be.

A fallible API seems better than killing the process as Git does,
since were in a library context and it would be bad if you could
perform denialofservice attacks on a server by sending it hash
collisions. (Although there are probably cheaper ways to mount a
denialofservice attack.)

The new API also returns an `ObjectId` rather than `[u8; 20]`; the
vast majority of `Hasher::digest()` users immediately convert the
result to `ObjectId`, so this will help eliminate a lot of cruft
across the tree. `ObjectId` also has nicer `Debug` and `Display`
instances than `[u8; 20]`, and should theoretically make supporting
the hash function transition easier, although I suspect further API
changes will be required for that anyway. I wasnt sure whether
this would be a good change, as not every digest identifies an
entry in the Git object database, but even many of the existing
uses for nonobject digests across the tree used the `ObjectId`
API anyway. Perhaps it would be best to have a separate nonalias
`Digest` type that `ObjectId` wraps, but this seems like the pragmatic
choice for now that sticks with current practice.

The old API remains in this commit, as well as a temporary
nonfallible but `ObjectId`returning `Hasher::finalize()`,
pending the migration of all intree callers.

I named the module `gix_hash::hasher` since `gix_hash::hash` seemed
like it would be confusing. This does mean that there is a function
and module with the same name, which is permitted but perhaps a
little strange.

Everything is reexported directly other than
`gix_features::hash::Write`, which moves along with the I/O
convenience functions into a new public submodule and becomes
`gix_hash::hasher::io::Write`, as that seems like a clearer name
to me, being akin to the `gix_hash::hasher` function but as an
`std::io::Write` wrapper.

Raw hashing is somewhere around 0.25 to 0.65 the speed of the
previous implementation, depending on the feature configuration
and whether the CPU supports hardwareaccelerated hashing. (The
more portable assembly in `sha1-asm` that doesnt require the SHA
instruction set doesnt seem to speed things up that much; in fact,
`sha1_smol` somehow regularly beats the assembly code used by `sha1`
on my i99880H MacBook Pro! Presumably this is why that path was
removed in newer versions of the `sha1` crate.)

Performance on an endtoend `gix no-repo pack verify` benchmark
using pack files from the Linux kernel Git server measures around
0.41 to 0.44 compared to the base commit on an M2 Max and a
Ryzen 7 5800X, both of which have hardware instructions for SHA1
acceleration that the previous implementation uses but this one does
not. On the i99880H, its around 0.58 to 0.60 the speed;
the slowdown is reduced by the older hardwares lack of SHA1
instructions.

The `sha1collisiondetection` crate from the Sequoia PGP project,
based on a modified C2Rust translation of the library used by Git,
was also considered; although its raw hashing performance seems
to measure around 1.121.15 the speed of `sha1-checked` on
x86, its indistinguishable from noise on the endtoend
benchmark, and on an M2 Max `sha1-checked` is consistently
around 1.03 the speed of `sha1collisiondetection` on that
benchmark. The `sha1collisiondetection` crate has also had a
soundness issue in the past due to the automatic C translation,
whereas `sha1-checked` has only one trivial `unsafe` block. On the
other hand, `sha1collisiondetection` is used by both Sequoia itself
and the `gitoid` crate, whereas rPGP is the only major user of
`sha1-checked`. I dont think theres a clear winner here.

The performance regression is very unfortunate, but the [SHAttered]
attack demonstrated a collision back in 2017, and the 2020 [SHA1 is
a Shambles] attack demonstrated a practical chosenprefix collision
that broke the use of SHA1 in OpenPGP, costing $75k to perform,
with an estimate of $45k to replicate at the time of publication and
$11k for a classical collision.

[SHAttered]: https://shattered.io/
[SHA1 is a Shambles]: https://sha-mbles.github.io/

Given the increase in GPU performance and production since then,
that puts the Git object format squarely at risk. Git mitigated this
attack in 2017; the algorithm is fairly general and detects all the
existing public collisions. My understanding is that an entirely new
cryptanalytic approach would be required to develop a collision attack
for SHA1 that would not be detected with very high probability.

I believe that the speed penalty could be mitigated, although not
fully eliminated, by implementing a version of the hardened SHA1
function that makes use of SIMD. For instance, the assembly code used
by `openssl speed sha1` on my i99880H measures around 830 MiB/s,
compared to the winning 580 MiB/s of `sha1_smol`; adding collision
detection support to that would surely incur a performance penalty,
but it is likely that it could be much more competitive with
the performance before this commit than the 310 MiB/s I get with
`sha1-checked`. I havent been able to find any existing work on
this; it seems that more or less everyone just uses the original
C library that Git does, presumably because nothing except Git and
OpenPGP is still relying on SHA1 anyway

The performance will never compete with the >2 GiB/s that can
be achieved with the x86 SHA instruction set extension, as the
`SHA1RNDS4` instruction sadly runs four rounds at a time while the
collision detection algorithm requires checks after every round,
but I believe SIMD would still offer a significant improvement,
and the AArch64 extension seems like it may be more flexible.

I know that these days the Git codebase has an additional faster
unsafe API without these checks that it tries to carefully use only
for operations that do not depend on hashing results for correctness
or safety. I personally believe thats not a terribly good idea,
as it seems easy to misuse in a case where correctness actually does
matter, but maybe thats just my Rust safety bias talking. I think
it would be better to focus on improving the performance of the safer
algorithm, as I think that many of the operations where the performance
penalty is the most painful are dealing with untrusted input anyway.

The `Hasher` struct gets a lot bigger; I dont know if this is
an issue or not, but if it is, it could potentially be boxed.

Closes: #585

 fix profiler_builtins build script to handle full path to profiler
 lib

LLVM_PROFILER_RT_LIB may be set to an absolute path (e.g., in Fedora builds),
but `-l` expects a library name, not a path. After #138273, this caused builds
to fail with a "could not find native static library" error.

This patch updates the build script to split the path into directory and
filename, using `cargo::rustc-link-search` for the directory and
`cargo::rustc-link-lib=+verbatim` for the file. This allows profiler_builtins to
correctly link the static library even when an absolute path is provided.

 run-make-support: set rustc dylib path for cargo wrapper
MIME-Version: 1.0
Content-Type: text/plain; charset="utf-8"
Content-Transfer-Encoding: 8bit

Some run-make tests invoke Cargo via run_make_support::cargo(), but fail to
execute correctly when rustc is built without rpath. In these setups, runtime
loading of rustcs shared libraries fails unless the appropriate dynamic library
path is set manually.

This commit updates the cargo() wrapper to call set_host_compiler_dylib_path(),
aligning its behavior with the existing rustc() wrapper:
https://github.com/rust-lang/rust/blob/f76c7367c6363d33ddb5a93b5de0d158b2d827f6/src/tools/run-make-support/src/external_deps/rustc.rs#L39

This ensures that Cargo invocations during tests inherit the necessary dylib
paths, avoiding errors related to missing shared libraries in rpath-less builds.

Fixes part of #140738
