Package: src:linux Version: 4.0.2-1 Severity: normal Dear Maintainer, While mounting /proc with the hidepid=1 option (or =2) users can't see forked processes. My /eetc/fstab entry: proc /proc proc defaults,hidepid=1,gid=4 0 I was testing ssh-agent and didn't see the running process with "ps auxww" even though it really was running and was visible as the admin user. Please try to reproduce this problem, it shouldn't be hard. Thanks. With regards, Han Boetes. -- Package-specific info: ** Version: Linux version 4.0.0-1-amd64 (debian-kernel@lists.debian.org) (gcc version 4.9.2 (Debian 4.9.2-16) ) #1 SMP Debian 4.0.2-1 (2015-05-11) ** Command line: BOOT_IMAGE=/vmlinuz-4.0.0-1-amd64 root=/dev/mapper/caesar-root ro quiet ** Not tainted ** Kernel log: [ 8856.098333] Enabling non-boot CPUs ...
