6 quota_selinux - Security Enhanced Linux Policy for the quota processes
7
9 Security-Enhanced Linux secures the quota processes via flexible manda‐
10 tory access control.
11 The quota processes execute with the quota_t SELinux type. You can
13 check if you have these processes running by executing the ps command
14 with the -Z qualifier.
15 For example:
17 ps -eZ | grep quota_t
19
23 The quota_t SELinux type can be entered via the quota_exec_t file type.
24 The default entrypoint paths for the quota_t domain are the following:
26 /sbin/quota(check|on), /usr/sbin/quota(check|on), /usr/sbin/con‐
28 vertquota
29
31 SELinux defines process types (domains) for each process running on the
32 system
33 You can see the context of a process using the -Z option to ps
35 Policy governs the access confined processes have to files. SELinux
37 quota policy is very flexible allowing users to setup their quota pro‐
38 cesses in as secure a method as possible.
39 The following process types are defined for quota:
41 quota_t, quota_nld_t
43 Note: semanage permissive -a quota_t can be used to make the process
45 type quota_t permissive. SELinux does not deny access to permissive
46 process types, but the AVC (SELinux denials) messages are still gener‐
47 ated.
48
51 SELinux policy is customizable based on least access required. quota
52 policy is extremely flexible and has several booleans that allow you to
53 manipulate the policy and run quota with the tightest access possible.
54 If you want to allow all domains to execute in fips_mode, you must turn
58 on the fips_mode boolean. Enabled by default.
59 setsebool -P fips_mode 1
61
65 The SELinux process type quota_t can manage files labeled with the fol‐
66 lowing file types. The paths listed are the default paths for these
67 file types. Note the processes UID still need to have DAC permissions.
68 quota_db_t
70 /a?quota.(user|group)
72 /etc/a?quota.(user|group)
73 /var/a?quota.(user|group)
74 /boot/a?quota.(user|group)
75 /var/spool/(.*/)?a?quota.(user|group)
76 /var/spool/cron/a?quota.(user|group)
77 /var/lib/openshift/a?quota.(user|group)
78 /var/lib/stickshift/a?quota.(user|group)
79 /home/[^/]+/a?quota.(user|group)
80 /home/a?quota.(user|group)
81
84 SELinux requires files to have an extended attribute to define the file
85 type.
86 You can see the context of a file using the -Z option to ls
88 Policy governs the access confined processes have to these files.
90 SELinux quota policy is very flexible allowing users to setup their
91 quota processes in as secure a method as possible.
92 STANDARD FILE CONTEXT
94 SELinux defines the file context types for the quota, if you wanted to
96 store files with these types in a diffent paths, you need to execute
97 the semanage command to sepecify alternate labeling and then use
98 restorecon to put the labels on disk.
99 semanage fcontext -a -t quota_nld_var_run_t '/srv/myquota_con‐
101 tent(/.*)?'
102 restorecon -R -v /srv/myquota_content
103 Note: SELinux often uses regular expressions to specify labels that
105 match multiple files.
106 The following file types are defined for quota:
108 quota_db_t
112 - Set files with the quota_db_t type, if you want to treat the files as
114 quota database content.
115 Paths:
118 /a?quota.(user|group), /etc/a?quota.(user|group),
119 /var/a?quota.(user|group), /boot/a?quota.(user|group),
120 /var/spool/(.*/)?a?quota.(user|group),
121 /var/spool/cron/a?quota.(user|group), /var/lib/open‐
122 shift/a?quota.(user|group), /var/lib/stick‐
123 shift/a?quota.(user|group), /home/[^/]+/a?quota.(user|group),
124 /home/a?quota.(user|group)
125 quota_exec_t
128 - Set files with the quota_exec_t type, if you want to transition an
130 executable to the quota_t domain.
131 Paths:
134 /sbin/quota(check|on), /usr/sbin/quota(check|on), /usr/sbin/con‐
135 vertquota
136 quota_flag_t
139 - Set files with the quota_flag_t type, if you want to treat the files
141 as quota flag data.
142 quota_nld_exec_t
146 - Set files with the quota_nld_exec_t type, if you want to transition
148 an executable to the quota_nld_t domain.
149 quota_nld_var_run_t
153 - Set files with the quota_nld_var_run_t type, if you want to store the
155 quota nld files under the /run or /var/run directory.
156 Note: File context can be temporarily modified with the chcon command.
160 If you want to permanently change the file context you need to use the
161 semanage fcontext command. This will modify the SELinux labeling data‐
162 base. You will need to use restorecon to apply the labels.
163
166 semanage fcontext can also be used to manipulate default file context
167 mappings.
168 semanage permissive can also be used to manipulate whether or not a
170 process type is permissive.
171 semanage module can also be used to enable/disable/install/remove pol‐
173 icy modules.
174 semanage boolean can also be used to manipulate the booleans
176 system-config-selinux is a GUI tool available to customize SELinux pol‐
179 icy settings.
