6 qmail_local_selinux - Security Enhanced Linux Policy for the qmail_lo‐
7 cal processes
8
10 Security-Enhanced Linux secures the qmail_local processes via flexible
11 mandatory access control.
12
13 The qmail_local processes execute with the qmail_local_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_local_t
20
21
22
24 The qmail_local_t SELinux type can be entered via the qmail_lo‐
25 cal_exec_t file type.
26
27 The default entrypoint paths for the qmail_local_t domain are the fol‐
28 lowing:
29
30 /var/qmail/bin/qmail-local
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_local policy is very flexible allowing users to setup their
40 qmail_local processes in as secure a method as possible.
41
42 The following process types are defined for qmail_local:
43
44 qmail_local_t
45
46 Note: semanage permissive -a qmail_local_t can be used to make the
47 process type qmail_local_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_local policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run qmail_local with the tight‐
56 est access possible.
57
58
59
60 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62
63 setsebool -P fips_mode 1
64
65
66
67 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69
70 setsebool -P nis_enabled 1
71

73
75 The SELinux process type qmail_local_t can manage files labeled with
76 the following file types. The paths listed are the default paths for
77 these file types. Note the processes UID still need to have DAC per‐
78 missions.

133 SELinux requires files to have an extended attribute to define the file
134 type.
135
136 You can see the context of a file using the -Z option to ls
137
138 Policy governs the access confined processes have to these files.
139 SELinux qmail_local policy is very flexible allowing users to setup
140 their qmail_local processes in as secure a method as possible.
141
142 The following file types are defined for qmail_local:
143
144
145
146 qmail_local_exec_t
147
148 - Set files with the qmail_local_exec_t type, if you want to transition
149 an executable to the qmail_local_t domain.
150
151
152
153 Note: File context can be temporarily modified with the chcon command.
154 If you want to permanently change the file context you need to use the
155 semanage fcontext command. This will modify the SELinux labeling data‐
156 base. You will need to use restorecon to apply the labels.
157
158
160 semanage fcontext can also be used to manipulate default file context
161 mappings.
162
163 semanage permissive can also be used to manipulate whether or not a
164 process type is permissive.
165
166 semanage module can also be used to enable/disable/install/remove pol‐
167 icy modules.
168
169 semanage boolean can also be used to manipulate the booleans
170
171
172 system-config-selinux is a GUI tool available to customize SELinux pol‐
173 icy settings.
