when I run fuzzer after create seed programs, with the code:
./core/afl-image-syscall/afl-fuzz -b btrfs -s fs/btrfs/btrfs_wrapper.so -e ./samples/evaluation/btrfs-00.image -S btrfs -y prog -i input -o output -m none -u 2 -- ./lkl/tools/lkl/btrfs-combined -t btrfs -p @@

I got the outcome as follows:
afl-fuzz 2.52b by [email protected]
[+] [fs-fuzz] shm name to store image buffer: btrfs
[+] [fs-fuzz] target wrapper (.so) path: fs/btrfs/btrfs_wrapper.so

can anyone tell me why I got this error?

I am trying to compile lkl and when i ran ./compile -t ext4 -c command, makefile recipe failed with error
AR /home/enigma/janus/lkl/tools/lkl/liblkl.a
LINK /home/enigma/janus/lkl/tools/lkl/fsfuzz
/usr/bin/ld: cannot find -larchive
collect2: error: ld returned 1 exit status
Can you please help me with what's -larchive library and where i can find it to solve the error.

when I run ./compile -t btrfs -c in lkl, i get some error msg:

compare with https://github.com/lkl/linux, I noticed that https://github.com/sslab-gatech/janus/tree/master/lkl missing gnss and input directory, so what's the problem?

lkl testsuit compail fail, i need some help, 3ks

While mounting ext4 image using sudo ./istat -i ../samples/evaluation/ext4-00.image -t ext4 -o ext4.istat command
I am getting error
tmp image: /tmp/tmpCELc3L
mount dir: /tmp/tmp6jexwh

   In some cases useful info is found in syslog - try
   dmesg | tail or so.

Can anyone help me figuring out what went wrong?

Please add to docs.

Hi all, could you please provide more details about how to generate minimal PoC(There is only one statement in the paper)? And how to guarantee its reproducibility as the image status is somehow like the accumulated status in Linux kernel? If I have any misunderstanding about this paper, please let me know.

To achieve this, JANUS currently uses a brute force approach to revert
every mutated byte and also tries to remove every invoked
file operation to check whether the kernel still crashes at the
expected location.

Please add to docs.
