Hi, Could somebody help me with syzkaller? I try to start fuzzing but I faced with issue (I used instructions https://github.com/google/syzkaller/blob/master/docs/linux/setup_ubuntu-host_qemu-vm_x86-64-kernel.md): ssh -i bullseye.id_rsa -p 10021 - o "StrictHostKeyChecking no" [email protected]...

datastore performs very badly on querying big entity lists from the DB. So far querying e.g. just all open bugs or bugs filtered by some criteria (label or manager) works fine, but we should avoid by all means the situations when we query thousands of entities of a type. For example, only for Linux...

Buzzer is a specialized BPF fuzzer. It can generate non-trivial BPF programs that pass validation. We could use that generation capability to get more meaningful programs. There is a corresponding issue for Buzzer. Filing here for visibility in the syzkaller repo as well.

As per the XFS maintainers, v4 XFS filesystems have known bugs that can only be fixed by moving to the v5 format. These include kernel hangs, use-after-frees, etc. As such, the XFS maintainers have been rejecting syzkaller reports involving a filesystem image if the image happened to be v4. To avo...

We're periodically getting errors like this: failed to poll jobs: request failed with 500 Internal Server Error: bug %BUG KEY% job creation failed: failed to get build %BUILD KEY%: API error 2 (datastore_v3: CONCURRENT_TRANSACTION): too much contention on these datastore entities. please try again....

Describe the bug I want to use syz-execprog to execute a prog. But ./syz-executor always failed when it tried to mmap_output. Following is the log message: 2023/05/18 18:49:16 executed programs: 0 2023/05/18 18:49:16 executing program 3: close(0xffffffffffffffff) 2023/05/18 18:49:27 SYZFATAL: execut...

Debugging info introduced in 71b00cf shows that scp fails due to Connection timed out. On syzbot it happens ~ 10-20 times a day. This is quite strange given that pool.Create only returns after vmimpl.WaitForSSH has successfully established an ssh connection. If we don't find the actual reason, we co...

From @tytso's reply in an LKML thread: What *would* be useful would be a search box on the top-level https://syzkaller.appspot.com/ where you could either enter an e-mail address like: [[email protected]](mailto:syzbot%[email protected]...
