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
12 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
16 For example:
17
18 ps -eZ | grep quota_t
19
20
21
23 The quota_t SELinux type can be entered via the quota_exec_t file type.
24
25 The default entrypoint paths for the quota_t domain are the following:
26
27 /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
34 You can see the context of a process using the -Z option to ps
35
36 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
40 The following process types are defined for quota:
41
42 quota_t, quota_nld_t
43
44 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
49
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
55
56
57 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
60 setsebool -P fips_mode 1
61
62
63
65 SELinux requires files to have an extended attribute to define the file
66 type.
67
68 You can see the context of a file using the -Z option to ls
69
70 Policy governs the access confined processes have to these files.
71 SELinux quota policy is very flexible allowing users to setup their
72 quota processes in as secure a method as possible.
73
74 STANDARD FILE CONTEXT
75
76 SELinux defines the file context types for the quota, if you wanted to
77 store files with these types in a different paths, you need to execute
78 the semanage command to specify alternate labeling and then use re‐
79 storecon to put the labels on disk.
80
81 semanage fcontext -a -t quota_exec_t '/srv/quota/content(/.*)?'
82 restorecon -R -v /srv/myquota_content
83
84 Note: SELinux often uses regular expressions to specify labels that
85 match multiple files.
86
87 The following file types are defined for quota:
88
89
90
91 quota_db_t
92
93 - Set files with the quota_db_t type, if you want to treat the files as
94 quota database content.
95
96
97 Paths:
98 /a?quota.(user|group), /etc/a?quota.(user|group),
99 /var/a?quota.(user|group), /boot/a?quota.(user|group),
100 /var/spool/(.*/)?a?quota.(user|group),
101 /var/spool/cron/a?quota.(user|group), /var/lib/open‐
102 shift/a?quota.(user|group), /var/lib/stick‐
103 shift/a?quota.(user|group), /home/[^/]+/a?quota.(user|group),
104 /home/a?quota.(user|group)
105
106
107 quota_exec_t
108
109 - Set files with the quota_exec_t type, if you want to transition an
110 executable to the quota_t domain.
111
112
113 Paths:
114 /sbin/quota(check|on), /usr/sbin/quota(check|on), /usr/sbin/con‐
115 vertquota
116
117
118 quota_flag_t
119
120 - Set files with the quota_flag_t type, if you want to treat the files
121 as quota flag data.
122
123
124
125 quota_nld_exec_t
126
127 - Set files with the quota_nld_exec_t type, if you want to transition
128 an executable to the quota_nld_t domain.
129
130
131
132 quota_nld_var_run_t
133
134 - Set files with the quota_nld_var_run_t type, if you want to store the
135 quota nld files under the /run or /var/run directory.
136
137
138
139 Note: File context can be temporarily modified with the chcon command.
140 If you want to permanently change the file context you need to use the
141 semanage fcontext command. This will modify the SELinux labeling data‐
142 base. You will need to use restorecon to apply the labels.
143
144
146 semanage fcontext can also be used to manipulate default file context
147 mappings.
148
149 semanage permissive can also be used to manipulate whether or not a
150 process type is permissive.
151
152 semanage module can also be used to enable/disable/install/remove pol‐
153 icy modules.
154
155 semanage boolean can also be used to manipulate the booleans
156
157
158 system-config-selinux is a GUI tool available to customize SELinux pol‐
159 icy settings.
