Name : tlpi
Product : Fedora 38
Version : 230522
Release : 1.fc38
URL :
https://man7.org/tlpi/index.html
Summary : Utilities to display namespaces and control groups
Description :
The book The Linux Programming Interface and training courses given by
man7.org are accompanied with a set of code examples. Some of these
examples are useful in their own right. This package includes the
following utilities.
- namespace_of Show the namespace memberships of one or more processes
in the context of the user or PID namespace
hierarchy. See the bundled source code for further
documentation.
- view_v2_cgroups Display one or more subtrees in the cgroups v2
hierarchy. The following info is displayed for each
cgroup: the cgroup type, the controllers enabled in
the cgroup, and the process and thread members of
the cgroup.
- ns_capable Test whether a process (identified by PID)
might--subject to LSM (Linux Security Module)
checks--have capabilities in a target namespace
(identified either by a /proc/PID/ns/xxx file or by
the PID of a process that is a member of a user
namespace).
Usage: ns_capable <source-pid> <namespace-file|target-pid>
In addition there are two small tools that implement special cases of
"namespace_of" usage. They could arguably be simpler to use in those
cases.
- pid_namespaces Show the PID namespace hierarchy.
- userns_overview Display a hierarchical view of the user namespaces
on the system along with the member processes for
each namespace.
