Description Marc Haber 2022-02-02 04:34:00 MST

Hi,

in qemu-user-static, /proc/self/stat contains a lot of zeroes. Sudo tries to read its tty from that file and fails if run in qemu-user-static.

The URL contains instructions how to reproduce this.

The reporter suggests to fall back to reading /proc/self/fd/0 if /proc/self/stat fails.

Greetings
Marc

I've added fallback code in https://www.sudo.ws/repos/sudo/rev/c32620c9f115 which should work around the qemu problem.

Fixed in sudo 1.9.10
