6 regex_milter_selinux - Security Enhanced Linux Policy for the
7 regex_milter processes
8
10 Security-Enhanced Linux secures the regex_milter processes via flexible
11 mandatory access control.
12 The regex_milter processes execute with the regex_milter_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep regex_milter_t
20
24 The regex_milter_t SELinux type can be entered via the regex_mil‐
25 ter_exec_t file type.
26 The default entrypoint paths for the regex_milter_t domain are the fol‐
28 lowing:
29 /usr/sbin/milter-regex
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 regex_milter policy is very flexible allowing users to setup their
40 regex_milter processes in as secure a method as possible.
41 The following process types are defined for regex_milter:
43 regex_milter_t
45 Note: semanage permissive -a regex_milter_t can be used to make the
47 process type regex_milter_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required.
54 regex_milter policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run regex_milter with the tight‐
56 est access possible.
57 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 setsebool -P authlogin_nsswitch_use_ldap 1
65 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 setsebool -P fips_mode 1
72 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Disabled by default.
77 setsebool -P kerberos_enabled 1
79 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84 setsebool -P nis_enabled 1
86 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 setsebool -P nscd_use_shm 1
93
97 The SELinux process type regex_milter_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.

143 SELinux requires files to have an extended attribute to define the file
144 type.
145 You can see the context of a file using the -Z option to ls
147 Policy governs the access confined processes have to these files.
149 SELinux regex_milter policy is very flexible allowing users to setup
150 their regex_milter processes in as secure a method as possible.
151 STANDARD FILE CONTEXT
153 SELinux defines the file context types for the regex_milter, if you
155 wanted to store files with these types in a diffent paths, you need to
156 execute the semanage command to sepecify alternate labeling and then
157 use restorecon to put the labels on disk.
158 semanage fcontext -a -t regex_milter_data_t '/srv/myregex_milter_con‐
160 tent(/.*)?'
161 restorecon -R -v /srv/myregex_milter_content
162 Note: SELinux often uses regular expressions to specify labels that
164 match multiple files.
165 The following file types are defined for regex_milter:
167 regex_milter_data_t
171 - Set files with the regex_milter_data_t type, if you want to treat the
173 files as regex milter content.
174 regex_milter_exec_t
178 - Set files with the regex_milter_exec_t type, if you want to transi‐
180 tion an executable to the regex_milter_t domain.
181 Note: File context can be temporarily modified with the chcon command.
185 If you want to permanently change the file context you need to use the
186 semanage fcontext command. This will modify the SELinux labeling data‐
187 base. You will need to use restorecon to apply the labels.
188
191 semanage fcontext can also be used to manipulate default file context
192 mappings.
193 semanage permissive can also be used to manipulate whether or not a
195 process type is permissive.
196 semanage module can also be used to enable/disable/install/remove pol‐
198 icy modules.
199 semanage boolean can also be used to manipulate the booleans
201 system-config-selinux is a GUI tool available to customize SELinux pol‐
204 icy settings.
