Subject: [Bug 216584] New: Undocumented mount option subset=pids for proc
Date: Fri, 14 Oct 2022 05:55:07 +0000 [thread overview]
Message-ID: <bug-216584-11311@https.bugzilla.kernel.org/> (raw)
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@kernel-bugs.osdl.org
Reporter: linux@philippwendler.de
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@gmail.com/
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@gmail.com/).
It might be useful to add a note about this as well.
