Fwd: Re: [syzbot] [fuse?] BUG: scheduling while atomic in __synchronize_srcu

[Marc Zyngier]

Hey syzkaller friends,

I can't seem to get syzkaller to go and test a branch in response to a
report (12b178b7c756664d2518). The message I sent was:

#syz test: git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms.git e2631e0328903f6e9711e4c253f2a855a167435b

I also tested

#syz test: git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms.git kvm-arm64/no-lazy-vgic-init

In both cases, I was told that the checkout had failed, which I find
puzzling... I assume I must be doing something wrong. Could you please
let me know what? Response from the bot attached for reference.

Thanks,

M.

Hi Marc,

Thanks for the report. There is some problem with the checkout on the
machine, I've filed https://github.com/google/syzkaller/issues/7082 to
track this.

Thanks for that. You also may want to look into some of the
submissions made to that entry, it looks like some script kiddies have
taken an interest in Syzkaller... :-/
