-.TH proc_pid 5 2023-08-15 "Linux man-pages 6.7"
-.SH NAME
-/proc/pid/, /proc/self/ \- process information
-.SH DESCRIPTION
-.TP
-.IR /proc/ pid /
-There is a numerical subdirectory for each running process; the
-subdirectory is named by the process ID.
-Each
-.IR /proc/ pid
-subdirectory contains the pseudo-files and directories described below.
-.IP
-The files inside each
-.IR /proc/ pid
-directory are normally owned by the effective user and
-effective group ID of the process.
-However, as a security measure, the ownership is made
-.I root:root
-if the process's "dumpable" attribute is set to a value other than 1.
-.IP
-Before Linux 4.11,
-.\" commit 68eb94f16227336a5773b83ecfa8290f1d6b78ce
-.I root:root
-meant the "global" root user ID and group ID
-(i.e., UID 0 and GID 0 in the initial user namespace).
-Since Linux 4.11,
-if the process is in a noninitial user namespace that has a
-valid mapping for user (group) ID 0 inside the namespace, then
-the user (group) ownership of the files under
-.IR /proc/ pid
-is instead made the same as the root user (group) ID of the namespace.
-This means that inside a container,
-things work as expected for the container "root" user.
-.IP
-The process's "dumpable" attribute may change for the following reasons:
-.RS
-.IP \[bu] 3
-The attribute was explicitly set via the
-.BR prctl (2)
-.B PR_SET_DUMPABLE
-operation.
-.IP \[bu]
-The attribute was reset to the value in the file
-.I /proc/sys/fs/suid_dumpable
-(described below), for the reasons described in
-.BR prctl (2).
-.RE
-.IP
-Resetting the "dumpable" attribute to 1 reverts the ownership of the
-.IR /proc/ pid /*
-files to the process's effective UID and GID.
-Note, however, that if the effective UID or GID is subsequently modified,
-then the "dumpable" attribute may be reset, as described in
-.BR prctl (2).
-Therefore, it may be desirable to reset the "dumpable" attribute
-.I after
-making any desired changes to the process's effective UID or GID.
-.TP
-.I /proc/self/
-This directory refers to the process accessing the
-.I /proc
-filesystem,
-and is identical to the
-.I /proc
-directory named by the process ID of the same process.
