6 qmail_local_selinux - Security Enhanced Linux Policy for the
7 qmail_local 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
25 qmail_local_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.

59
60 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63
64 setsebool -P authlogin_nsswitch_use_ldap 1
65
66
67
68 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70
71 setsebool -P fips_mode 1
72
73
74
75 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Enabled by default.
77
78 setsebool -P kerberos_enabled 1
79
80
81
82 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84
85 setsebool -P nis_enabled 1
86
87
88
89 If you want to allow confined applications to use nscd shared memory,
90 you must turn on the nscd_use_shm boolean. Disabled by default.
91
92 setsebool -P nscd_use_shm 1
93
94
95
97 The SELinux process type qmail_local_t can manage files labeled with
98 the following file types. The paths listed are the default paths for
99 these file types. Note the processes UID still need to have DAC per‐
100 missions.
101

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 qmail_local policy is very flexible allowing users to setup
155 their qmail_local processes in as secure a method as possible.
156
157 The following file types are defined for qmail_local:
158
159
160
161 qmail_local_exec_t
162
163 - Set files with the qmail_local_exec_t type, if you want to transition
164 an executable to the qmail_local_t domain.
165
166
167
168 Note: File context can be temporarily modified with the chcon command.
169 If you want to permanently change the file context you need to use the
170 semanage fcontext command. This will modify the SELinux labeling data‐
171 base. You will need to use restorecon to apply the labels.
172
173
175 semanage fcontext can also be used to manipulate default file context
176 mappings.
177
178 semanage permissive can also be used to manipulate whether or not a
179 process type is permissive.
180
181 semanage module can also be used to enable/disable/install/remove pol‐
182 icy modules.
183
184 semanage boolean can also be used to manipulate the booleans
185
186
187 system-config-selinux is a GUI tool available to customize SELinux pol‐
188 icy settings.
