    Since this looks secp256k1 related I tried reproducing on a separate secp build but couldn’t. This could very well be a compiler/linker bug.

    I am surprised that I’m the only one running into this, we don’t have a x86 ASan job anywhere? I think I first observed this sometime mid last year.

    This looks familiar. Can you try if -fomit-frame-pointer fixes it?

    Not using -DUSE_ASM_X86_64=1 obviously works. Could be a work around once #31379 is merged.

    I believe the explanation here is just that they’re incompatible. The asm code in libsecp256k1 requires many registers; an amount which is generally available in builds. But presumably, asan instrumentation reduces the set of general-purpose available register from use in the instrumentation itself, and as a result the code doesn’t compile anymore.

    You can also set -O1 instead of -O0, but I guess you don’t want that?

    I wonder if this is related to it: https://github.com/llvm/llvm-project/blob/1c4e9863fa1cba6d28be92026e0912808b01780d/llvm/lib/Transforms/Instrumentation/AddressSanitizer.cpp#L3096-L3107. Currently limited to 32-bit but maybe it’s also broken for 64-bit?

    You can also set -O1 instead of -O0, but I guess you don’t want that?

    -O1 works but -O0 does not. Could be a workaround as well.

    Interestingly using afl-clang-{lto,fast} does not fail to compile /bitcoin/src/secp256k1/src/secp256k1.c but it does fail to link bitcoind with a similar message: error: LLVM gold plugin: inline assembly requires more registers than available at line 2171 (maybe an entirely separate issue).

    Does -O0 even work with -DUSE_ASM_X86_64=1, absent asan?

    Looks like it.

    You can also set -O1 instead of -O0, but I guess you don’t want that?

    Just re-read your message, isn’t -O2 our default? i.e. I don’t think I was using -O0 when I first saw this.

    You explicitly set it to the empty string in -DCMAKE_CXX_FLAGS_RELWITHDEBINFO="" and IIRC the default for compilers is -O0, so I presumed that this was intentional.

    Ah yes. The actual setup involved setting flags like we do in oss-fuzz https://github.com/google/oss-fuzz/blob/1472130318ff69f8dcfc44db7aa9fe0610423c57/projects/bitcoin-core/build.sh#L70. So it doesn’t work with O0 or O2.

    I wonder if the afl++ build failure is also why we don’t see any afl++ fuzzing on oss-fuzz anymore (https://github.com/google/oss-fuzz/issues/13020).

    oss-fuzz has -O1 set, so I think the build should succeed. See also https://oss-fuzz-build-logs.storage.googleapis.com/index.html#bitcoin-core

    For me the afl-clang-{fast,lto} build fails even with -O1 but you’re right the oss-fuzz build logs look fine. I’ll try using the afl++ version they use, maybe there’s a bug in the newer version I use. In any case the afl++ issue seems separate from the secp asm failure with plain clang (even though the error message is almost the same).
  16. dergoegge commented at 2:29 pm on February 21, 2025: member

    So turns out newer versions of afl++ (i.e. newer than the one oss-fuzz is using) will insert -flto when -fcf-protection is detected. That results in -flto -fcf-protection -fsanitize=address and for some reason that combination doesn’t work, not sure if it’s just not supported or there’s a bug but for us a simple workaround is to simply set -DENABLE_HARDENING=OFF when fuzzing with afl++ and ASan on x86. The PR that changed this on the afl++ side is: https://github.com/AFLplusplus/AFLplusplus/pull/1966.

    In conclusion, for a plain clang build on x86 with ASan use either -O1 or disable the secp256k1 custom assembly and for a afl-clang-* build with ASan use our -DENABLE_HARDENING=OFF cmake option (this will become relevant for our oss-fuzz build once they bump afl++).

    I don’t think there is anything for us left to do here, so closing.

    Now that we’ve removed ENABLE_HARDENING this is happening again. The suggested workaround of injecting flags manually via APPEND_* does not work.

    This is an issue for me with https://github.com/dergoegge/fuzzamoto and it’’ll also be a problem on oss-fuzz, when they bump their afl++ version.

    I think the issue here is similar to #32323. The user provided flags (to override the hardening options) aren’t checked during CMake compiler checks, which means the disabling doesn’t actually happen when using afl. As far as I can tell this also isn’t fixed by #32367. Will open a PR to further patch fcf-protection out.

    To clarify, now it is a configure failure, as opposed to a build (make) failure?

    edit: and the new steps to reproduce are https://github.com/dergoegge/fuzzamoto/blob/master/Dockerfile ?

    It’s still a build failure, with no way to override the offending flag, as the APPEND options don’t currently work properly.

    Could someone provide configuration options and a line from the verbose build to show what exactly is broken?

  28. maflcko commented at 5:24 pm on April 30, 2025: member

    I checked the original non-afl asan dockerfile and the existing workaround should still apply there (Don’t use -O0, or disable secp256k1 asm).

    Thus, my guess is the new issue is about afl only and the new dockerfile is https://github.com/dergoegge/fuzzamoto/blob/master/Dockerfile?

    @davidgumberg

    Could someone provide configuration options and a line from the verbose build to show what exactly is broken?

    Reproduced as follows:

    Thank you!

    Could you please try the following patch:

    My guess is that /AFLplusplus/afl-clang-fast++ fails to handle the -fcf-protection=full -fcf-protection=none flags properly.
