==============================================================
|
|
|
|
This file contains the documetation for the sysctl files in
|
|
/proc/sys/user.
|
|
|
|
The files in this directory can be used to override the default
|
|
limits on the number of namespaces and other objects that have
|
|
per user per user namespace limits.
|
|
|
|
The primary purpose of these limits is to stop programs that
|
|
malfunction and attempt to create a ridiculous number of objects,
|
|
before the malfunction becomes a system wide problem. It is the
|
|
intention that the defaults of these limits are set high enough that
|
|
no program in normal operation should run into these limits.
|
|
|
|
The creation of per user per user namespace objects are charged to
|
|
the user in the user namespace who created the object and
|
|
verified to be below the per user limit in that user namespace.
|
|
|
|
The creation of objects is also charged to all of the users
|
|
who created user namespaces the creation of the object happens
|
|
in (user namespaces can be nested) and verified to be below the per user
|
|
limits in the user namespaces of those users.
|
|
|
|
This recursive counting of created objects ensures that creating a
|
|
user namespace does not allow a user to escape their current limits.
|
|
|
|
Currently, these files are in /proc/sys/user:
|
|
|
|
- max_cgroup_namespaces
|
|
|
|
The maximum number of cgroup namespaces that any user in the current
|
|
user namespace may create.
|
|
|
|
- max_ipc_namespaces
|
|
|
|
The maximum number of ipc namespaces that any user in the current
|
|
user namespace may create.
|
|
|
|
- max_mnt_namespaces
|
|
|
|
The maximum number of mount namespaces that any user in the current
|
|
user namespace may create.
|
|
|
|
- max_net_namespaces
|
|
|
|
The maximum number of network namespaces that any user in the
|
|
current user namespace may create.
|
|
|
|
- max_pid_namespaces
|
|
|
|
The maximum number of pid namespaces that any user in the current
|
|
user namespace may create.
|
|
|
|
- max_user_namespaces
|
|
|
|
The maximum number of user namespaces that any user in the current
|
|
user namespace may create.
|
|
|
|
- max_uts_namespaces
|
|
|
|
The maximum number of user namespaces that any user in the current
|
|
user namespace may create.
