syzkaller regression "failed to run executor"

[cpaasch]

Hello,

I updated to latest master and found that with commit a38fb99 a regression was introduced causing continuous error-messages à la:

2024/05/24 15:42:10 vm-2: crash: SYZFATAL: failed to run executor version: failed to run executor version: failed to run ["/syz-executor" "version"]: exi

Please let me know if I can be of any help to debug this.

Was there anything after "exi"?
Could you please build "make executor" and run "bin/linux-amd64/syz-executor version" on your target machine? Does it fail? How?

Nope, nothing!

Could you please build "make executor" and run "bin/linux-amd64/syz-executor version" on your target machine? Does it fail? How?

It works:

$ bin/linux_amd64/syz-executor version
linux amd64 3efdd6dbffe8a6c3c20a04e835fd00c973fcb9a2 a10a183e260f0ea1a0c37e84ca5c60f28c13e3fd

Humm... This is strange. I don't have any ideas at the moment. syz-fuzzer just executes "syz-executor version" in the VM...
