quota_selinux(8)	     SELinux Policy quota	      quota_selinux(8)

NAME
       quota_selinux - Security Enhanced Linux Policy for the quota processes

DESCRIPTION
       Security-Enhanced Linux secures the quota processes via flexible manda‐
       tory access control.

       The quota processes execute with the  quota_t  SELinux  type.  You  can
       check  if  you have these processes running by executing the ps command
       with the -Z qualifier.

       For example:

       ps -eZ | grep quota_t

ENTRYPOINTS
       The quota_t SELinux type can be entered via the quota_exec_t file type.

       The default entrypoint paths for the quota_t domain are the following:

       /sbin/quota(check|on),	 /usr/sbin/quota(check|on),	/usr/sbin/con‐
       vertquota

PROCESS TYPES
       SELinux defines process types (domains) for each process running on the
       system

       You can see the context of a process using the -Z option to ps

       Policy governs the access confined processes have  to  files.   SELinux
       quota  policy is very flexible allowing users to setup their quota pro‐
       cesses in as secure a method as possible.

       The following process types are defined for quota:

       quota_t, quota_nld_t

       Note: semanage permissive -a quota_t can be used to  make  the  process
       type  quota_t  permissive.  SELinux  does not deny access to permissive
       process types, but the AVC (SELinux denials) messages are still	gener‐
       ated.

BOOLEANS
       SELinux	policy	is customizable based on least access required.	 quota
       policy is extremely flexible and has several booleans that allow you to
       manipulate the policy and run quota with the tightest access possible.

       If  you	want  to deny any process from ptracing or debugging any other
       processes, you  must  turn  on  the  deny_ptrace	 boolean.  Enabled  by
       default.

       setsebool -P deny_ptrace 1

       If you want to allow all domains to use other domains file descriptors,
       you must turn on the domain_fd_use boolean. Enabled by default.

       setsebool -P domain_fd_use 1

       If you want to allow all domains to have the kernel load	 modules,  you
       must  turn  on  the  domain_kernel_load_modules	boolean.  Disabled  by
       default.

       setsebool -P domain_kernel_load_modules 1

       If you want to allow all domains to execute in fips_mode, you must turn
       on the fips_mode boolean. Enabled by default.

       setsebool -P fips_mode 1

       If you want to enable reading of urandom for all domains, you must turn
       on the global_ssp boolean. Disabled by default.

       setsebool -P global_ssp 1

NSSWITCH DOMAIN
       If you want to allow users to resolve user passwd entries directly from
       ldap rather then using a sssd server for the quota_nld_t, you must turn
       on the authlogin_nsswitch_use_ldap boolean.

       setsebool -P authlogin_nsswitch_use_ldap 1

       If you want to allow confined applications to run with kerberos for the
       quota_nld_t, you must turn on the kerberos_enabled boolean.

       setsebool -P kerberos_enabled 1

MANAGED FILES
       The SELinux process type quota_t can manage files labeled with the fol‐
       lowing file types.  The paths listed are the default  paths  for	 these
       file types.  Note the processes UID still need to have DAC permissions.

       quota_db_t

	    /a?quota.(user|group)
	    /etc/a?quota.(user|group)
	    /var/a?quota.(user|group)
	    /boot/a?quota.(user|group)
	    /var/spool/(.*/)?a?quota.(user|group)
	    /var/lib/openshift/a?quota.(user|group)
	    /var/lib/stickshift/a?quota.(user|group)
	    /home/[^/]*/a?quota.(user|group)
	    /home/a?quota.(user|group)

FILE CONTEXTS
       SELinux requires files to have an extended attribute to define the file
       type.

       You can see the context of a file using the -Z option to ls

       Policy governs the access  confined  processes  have  to	 these	files.
       SELinux	quota  policy  is  very flexible allowing users to setup their
       quota processes in as secure a method as possible.

       STANDARD FILE CONTEXT

       SELinux defines the file context types for the quota, if you wanted  to
       store  files  with  these types in a diffent paths, you need to execute
       the semanage command  to	 sepecify  alternate  labeling	and  then  use
       restorecon to put the labels on disk.

       semanage fcontext -a -t quota_db_t '/srv/quota/content(/.*)?'
       restorecon -R -v /srv/myquota_content

       Note:  SELinux  often  uses  regular expressions to specify labels that
       match multiple files.

       The following file types are defined for quota:

       quota_db_t

       - Set files with the quota_db_t type, if you want to treat the files as
       quota database content.

       Paths:
	    /a?quota.(user|group),		    /etc/a?quota.(user|group),
	    /var/a?quota.(user|group),		   /boot/a?quota.(user|group),
	    /var/spool/(.*/)?a?quota.(user|group),		/var/lib/open‐
	    shift/a?quota.(user|group),			       /var/lib/stick‐
	    shift/a?quota.(user|group),	     /home/[^/]*/a?quota.(user|group),
	    /home/a?quota.(user|group)

       quota_exec_t

       - Set files with the quota_exec_t type, if you want  to	transition  an
       executable to the quota_t domain.

       Paths:
	    /sbin/quota(check|on),  /usr/sbin/quota(check|on),	/usr/sbin/con‐
	    vertquota

       quota_flag_t

       - Set files with the quota_flag_t type, if you want to treat the	 files
       as quota flag data.

       quota_nld_exec_t

       -  Set  files with the quota_nld_exec_t type, if you want to transition
       an executable to the quota_nld_t domain.

       quota_nld_var_run_t

       - Set files with the quota_nld_var_run_t type, if you want to store the
       quota nld files under the /run or /var/run directory.

       Note:  File context can be temporarily modified with the chcon command.
       If you want to permanently change the file context you need to use  the
       semanage fcontext command.  This will modify the SELinux labeling data‐
       base.  You will need to use restorecon to apply the labels.

COMMANDS
       semanage fcontext can also be used to manipulate default	 file  context
       mappings.

       semanage	 permissive  can  also	be used to manipulate whether or not a
       process type is permissive.

       semanage module can also be used to enable/disable/install/remove  pol‐
       icy modules.

       semanage boolean can also be used to manipulate the booleans

       system-config-selinux is a GUI tool available to customize SELinux pol‐
       icy settings.
