6 qmail_start_selinux - Security Enhanced Linux Policy for the
7 qmail_start processes
8
10 Security-Enhanced Linux secures the qmail_start processes via flexible
11 mandatory access control.
12
13 The qmail_start processes execute with the qmail_start_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep qmail_start_t
20
21
22
24 The qmail_start_t SELinux type can be entered via the
25 qmail_start_exec_t file type.
26
27 The default entrypoint paths for the qmail_start_t domain are the fol‐
28 lowing:
29
30 /var/qmail/bin/qmail-start
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 Policy governs the access confined processes have to files. SELinux
39 qmail_start policy is very flexible allowing users to setup their
40 qmail_start processes in as secure a method as possible.
41
42 The following process types are defined for qmail_start:
43
44 qmail_start_t
45
46 Note: semanage permissive -a qmail_start_t can be used to make the
47 process type qmail_start_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required.
54 qmail_start policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run qmail_start with the tight‐
56 est access possible.

93
94
95

97 daemons_enable_cluster_mode boolean. Disabled by default.
98
99 setsebool -P daemons_enable_cluster_mode 1
100
101
102
103 If you want to allow all domains to have the kernel load modules, you
104 must turn on the domain_kernel_load_modules boolean. Disabled by
105 default.
106
107 setsebool -P domain_kernel_load_modules 1
108
109
110
111 If you want to allow all domains to execute in fips_mode, you must turn
112 on the fips_mode boolean. Enabled by default.
113
114 setsebool -P fips_mode 1
115
116
117
118 If you want to enable reading of urandom for all domains, you must turn
119 on the global_ssp boolean. Disabled by default.
120
121 setsebool -P global_ssp 1
122
123
124
125 If you want to enable support for upstart as the init program, you must
126 turn on the init_upstart boolean. Enabled by default.
127
128 setsebool -P init_upstart 1

133 The SELinux process type qmail_start_t can manage files labeled with
134 the following file types. The paths listed are the default paths for
135 these file types. Note the processes UID still need to have DAC per‐
136 missions.

197 SELinux requires files to have an extended attribute to define the file
198 type.
199
200 You can see the context of a file using the -Z option to ls
201
202 Policy governs the access confined processes have to these files.
203 SELinux qmail_start policy is very flexible allowing users to setup
204 their qmail_start processes in as secure a method as possible.
205
206 The following file types are defined for qmail_start:
207
208
209
210 qmail_start_exec_t
211
212 - Set files with the qmail_start_exec_t type, if you want to transition
213 an executable to the qmail_start_t domain.
214
215
216
217 Note: File context can be temporarily modified with the chcon command.
218 If you want to permanently change the file context you need to use the
219 semanage fcontext command. This will modify the SELinux labeling data‐
220 base. You will need to use restorecon to apply the labels.
221
222
224 semanage fcontext can also be used to manipulate default file context
225 mappings.
226
227 semanage permissive can also be used to manipulate whether or not a
228 process type is permissive.
229
230 semanage module can also be used to enable/disable/install/remove pol‐
231 icy modules.
232
233 semanage boolean can also be used to manipulate the booleans
234
235
236 system-config-selinux is a GUI tool available to customize SELinux pol‐
237 icy settings.
