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/convertquota
28
30 SELinux defines process types (domains) for each process running on the
31 system
32
33 You can see the context of a process using the -Z option to ps
34
35 Policy governs the access confined processes have to files. SELinux
36 quota policy is very flexible allowing users to setup their quota pro‐
37 cesses in as secure a method as possible.
38
39 The following process types are defined for quota:
40
41 quota_t, quota_nld_t
42
43 Note: semanage permissive -a quota_t can be used to make the process
44 type quota_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
48
50 SELinux policy is customizable based on least access required. quota
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run quota with the tightest access possible.
53
54
55
56 If you want to allow all daemons the ability to read/write terminals,
57 you must turn on the allow_daemons_use_tty boolean. Disabled by
58 default.
59
60 setsebool -P allow_daemons_use_tty 1
61
62
63
64 If you want to allow all domains to use other domains file descriptors,
65 you must turn on the allow_domain_fd_use boolean. Enabled by default.
66
67 setsebool -P allow_domain_fd_use 1
68
69
70
71 If you want to allow sysadm to debug or ptrace all processes, you must
72 turn on the allow_ptrace boolean. Disabled by default.
73
74 setsebool -P allow_ptrace 1
75
76
77
78 If you want to allow all domains to have the kernel load modules, you
79 must turn on the domain_kernel_load_modules boolean. Disabled by
80 default.
81
82 setsebool -P domain_kernel_load_modules 1
83
84
85
86 If you want to allow all domains to execute in fips_mode, you must turn
87 on the fips_mode boolean. Enabled by default.
88
89 setsebool -P fips_mode 1
90
91
92
93 If you want to enable reading of urandom for all domains, you must turn
94 on the global_ssp boolean. Disabled by default.
95
96 setsebool -P global_ssp 1
97
98
99
101 The SELinux process type quota_t can manage files labeled with the fol‐
102 lowing file types. The paths listed are the default paths for these
103 file types. Note the processes UID still need to have DAC permissions.

148 SELinux requires files to have an extended attribute to define the file
149 type.
150
151 You can see the context of a file using the -Z option to ls
152
153 Policy governs the access confined processes have to these files.
154 SELinux quota policy is very flexible allowing users to setup their
155 quota processes in as secure a method as possible.
156
157 STANDARD FILE CONTEXT
158
159 SELinux defines the file context types for the quota, if you wanted to
160 store files with these types in a diffent paths, you need to execute
161 the semanage command to sepecify alternate labeling and then use
162 restorecon to put the labels on disk.
163
164 semanage fcontext -a -t quota_nld_var_run_t '/srv/myquota_con‐
165 tent(/.*)?'
166 restorecon -R -v /srv/myquota_content
167
168 Note: SELinux often uses regular expressions to specify labels that
169 match multiple files.
170
171 The following file types are defined for quota:
172
173
174
175 quota_db_t
176
177 - Set files with the quota_db_t type, if you want to treat the files as
178 quota database content.
179
180
181 Paths:
182 /a?quota.(user|group), /var/a?quota.(user|group),
183 /etc/a?quota.(user|group), /boot/a?quota.(user|group),
184 /var/spool/(.*/)?a?quota.(user|group), /var/lib/open‐
185 shift/a?quota.(user|group), /var/lib/stick‐
186 shift/a?quota.(user|group), /home/a?quota.(user|group)
187
188
189 quota_exec_t
190
191 - Set files with the quota_exec_t type, if you want to transition an
192 executable to the quota_t domain.
193
194
195 Paths:
196 /sbin/quota(check|on), /usr/sbin/convertquota
197
198
199 quota_flag_t
200
201 - Set files with the quota_flag_t type, if you want to treat the files
202 as quota flag data.
203
204
205
206 quota_nld_exec_t
207
208 - Set files with the quota_nld_exec_t type, if you want to transition
209 an executable to the quota_nld_t domain.
210
211
212
213 quota_nld_var_run_t
214
215 - Set files with the quota_nld_var_run_t type, if you want to store the
216 quota nld files under the /run or /var/run directory.
217
218
219
220 Note: File context can be temporarily modified with the chcon command.
221 If you want to permanently change the file context you need to use the
222 semanage fcontext command. This will modify the SELinux labeling data‐
223 base. You will need to use restorecon to apply the labels.
224
225
227 semanage fcontext can also be used to manipulate default file context
228 mappings.
229
230 semanage permissive can also be used to manipulate whether or not a
231 process type is permissive.
232
233 semanage module can also be used to enable/disable/install/remove pol‐
234 icy modules.
235
236 semanage boolean can also be used to manipulate the booleans
237
238
239 system-config-selinux is a GUI tool available to customize SELinux pol‐
240 icy settings.
