https://bugzilla.kernel.org/show_bug.cgi?id=216584 Bug ID: 216584 Summary: Undocumented mount option subset=pids for proc Product: Documentation Version: unspecified Hardware: All OS: Linux Status: NEW Severity: normal Priority: P1 Component: man-pages Assignee: documentation_man-pages@xxxxxxxxxxxxxxxxxxxx Reporter: linux@xxxxxxxxxxxxxxxxx Regression: No Since Linux 5.8, proc can be mounted with options subset=pids to hide all non-task-related information. This is missing from proc(5). Original patch: https://lore.kernel.org/all/20200423200316.164518-6-gladkov.alexey@xxxxxxxxx/ The kernel documentation shows the option: https://www.kernel.org/doc/html/latest/filesystems/proc.html#mount-options This option is useful when mounting proc for a container nested for example in a Docker container that hides certain parts of /proc, otherwise one is not allowed to mount /proc (https://lkml.kernel.org/lkml/cover.1597931457.git.gladkov.alexey@xxxxxxxxx/). It might be useful to add a note about this as well. -- You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.
