Resetting the "dumpable" attribute to 1 reverts the ownership of the /proc/[pid]/* files to the process's real UID and real GID./proc/[pid]/attr The files in this directory provide an API for security mod‐ ules.This makes it impossible to learn whether any user is running a specific program (so long as the program doesn't otherwise reveal itself by its behavior).2 As for mode 1, but in addition the /proc/[pid] directories belonging to other users become invisible.

In SELinux, a process can set only its own /proc/[pid]/attr/fscreate attribute.In SELinux, this is needed to support role/domain transitions, and execve(2) is the preferred point to make such transitions because it offers better control over the initialization of the process in the new security label and the inheritance of state.In SELinux, this attribute is reset on execve(2) so that the new program reverts to the default behavior for any execve(2) calls that it may make.The proc filesystem is a pseudo-filesystem which provides an interface to kernel data structures. Typically, it is mounted automatically by the system, but it can also be mounted manually using a command such as: mount -t proc proc /proc Most of the files in the proc filesystem are read-only, but some files are writable, allowing kernel variables to be changed.Mount options The proc filesystem supports the following mount options: hidepid=n (since Linux 3.3) This option controls who can access the information in /proc/[pid] directories.
