Hello, is it possible to provide american-fuzzy-lop package on s390x ? I was able to build it in LLVM mode and use it successfully on s390x. Regards Alex
Instructions how to build it: dnf install -y llvm-devel clang-devel curl -O https://lcamtuf.coredump.cx/afl/releases/afl-latest.tgz tar xvzf afl-latest.tgz cd afl-2.52b AFL_NO_X86=1 make AFL_NO_X86=1 make -C llvm_mode export AFL_PATH=~/afl-2.52b
Possibly. What would help would be a patch to the spec file which enables this.
Ok, i'll see what can be done, my first time changing a Fedora package :)
Created attachment 1820113 [details] AFL s390x support
I managed to build an RPM on S390X and uploaded the SPEC patch i used. I'm not familiar with Fedora package building, i think we need to add conditional statements to the SPEC because on an architecture != x86, only afl-clang-fast and afl-clang-fast++ are available. The wrappers afl-gcc, afl-g++, afl-clang and afl-clang++ are only for X86.
That patch disables x86 support. However I adapted it a bit to try to make it work with both. Scratch build: https://koji.fedoraproject.org/koji/taskinfo?taskID=75046930
Second try: https://koji.fedoraproject.org/koji/taskinfo?taskID=75047887
Can you try out this package? https://koji.fedoraproject.org/koji/taskinfo?taskID=75048287
Thank you very much. I have to use fedora 36, right ? No way to install it on F34 ?
Nevermind, i'll setup a QEMU KVM instance, test it and report back.
I think it should be installable on F34. You might have to upgrade clang (only) though.
I installed F36 with QEMU KVM and then AFL packages. But missing afl-clang-fast ? [root@fedora ~]# rpm --install *.rpm package american-fuzzy-lop-debugsource-3.14c-4.fc36.s390x is already installed package american-fuzzy-lop-debuginfo-3.14c-4.fc36.s390x is already installed package american-fuzzy-lop-3.14c-4.fc36.s390x is already installed package american-fuzzy-lop-clang-3.14c-4.fc36.s390x is already installed package american-fuzzy-lop-clang-debuginfo-3.14c-4.fc36.s390x is already installed [root@fedora ~]# afl-cmin afl-cmin afl-cmin.bash [root@fedora ~]# afl-cmin [root@fedora ~]# afl- afl-analyze afl-fuzz afl-showmap afl-whatsup afl-cmin afl-gotcpu afl-system-config afl-cmin.bash afl-plot afl-tmin
Weird, so they are actually symlinks to afl-cc and afl-c++. Let's see if this one works: https://koji.fedoraproject.org/koji/taskinfo?taskID=75051663
It looks good now. [root@fedora ~]# afl- afl-analyze afl-clang-fast++ afl-gotcpu afl-tmin afl-c++ afl-cmin afl-plot afl-whatsup afl-cc afl-cmin.bash afl-showmap afl-clang-fast afl-fuzz afl-system-config I also managed to get my fuzzing tests running on Fedora 36 with those packages. Thanks a lot.
One question. The AFL packages for s390x will not be backported to F34 and F35 ?
Sure I can do them for f34 & f35.
Thank you.
