6 mandb_selinux - Security Enhanced Linux Policy for the mandb processes
7
9 Security-Enhanced Linux secures the mandb processes via flexible manda‐
10 tory access control.
11 The mandb processes execute with the mandb_t SELinux type. You can
13 check if you have these processes running by executing the ps command
14 with the -Z qualifier.
15 For example:
17 ps -eZ | grep mandb_t
19
23 The mandb_t SELinux type can be entered via the mandb_exec_t file type.
24 The default entrypoint paths for the mandb_t domain are the following:
26 /etc/cron.(daily|weekly)/man-db.*, /usr/bin/mandb
28
30 SELinux defines process types (domains) for each process running on the
31 system
32 You can see the context of a process using the -Z option to ps
34 Policy governs the access confined processes have to files. SELinux
36 mandb policy is very flexible allowing users to setup their mandb pro‐
37 cesses in as secure a method as possible.
38 The following process types are defined for mandb:
40 mandb_t
42 Note: semanage permissive -a mandb_t can be used to make the process
44 type mandb_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
50 SELinux policy is customizable based on least access required. mandb
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run mandb with the tightest access possible.
53 If you want to allow all domains to execute in fips_mode, you must turn
57 on the fips_mode boolean. Enabled by default.
58 setsebool -P fips_mode 1
60
64 The SELinux process type mandb_t can manage files labeled with the fol‐
65 lowing file types. The paths listed are the default paths for these
66 file types. Note the processes UID still need to have DAC permissions.

109 SELinux requires files to have an extended attribute to define the file
110 type.
111 You can see the context of a file using the -Z option to ls
113 Policy governs the access confined processes have to these files.
115 SELinux mandb policy is very flexible allowing users to setup their
116 mandb processes in as secure a method as possible.
117 STANDARD FILE CONTEXT
119 SELinux defines the file context types for the mandb, if you wanted to
121 store files with these types in a diffent paths, you need to execute
122 the semanage command to sepecify alternate labeling and then use
123 restorecon to put the labels on disk.
124 semanage fcontext -a -t mandb_lock_t '/srv/mymandb_content(/.*)?'
126 restorecon -R -v /srv/mymandb_content
127 Note: SELinux often uses regular expressions to specify labels that
129 match multiple files.
130 The following file types are defined for mandb:
132 mandb_cache_t
136 - Set files with the mandb_cache_t type, if you want to store the files
138 under the /var/cache directory.
139 Paths:
142 /var/cache/man(/.*)?, /opt/local/share/man(/.*)?
143 mandb_exec_t
146 - Set files with the mandb_exec_t type, if you want to transition an
148 executable to the mandb_t domain.
149 Paths:
152 /etc/cron.(daily|weekly)/man-db.*, /usr/bin/mandb
153 mandb_home_t
156 - Set files with the mandb_home_t type, if you want to store mandb
158 files in the users home directory.
159 Paths:
162 /root/.manpath, /home/[^/]+/.manpath
163 mandb_lock_t
166 - Set files with the mandb_lock_t type, if you want to treat the files
168 as mandb lock data, stored under the /var/lock directory
169 Note: File context can be temporarily modified with the chcon command.
173 If you want to permanently change the file context you need to use the
174 semanage fcontext command. This will modify the SELinux labeling data‐
175 base. You will need to use restorecon to apply the labels.
176
179 semanage fcontext can also be used to manipulate default file context
180 mappings.
181 semanage permissive can also be used to manipulate whether or not a
183 process type is permissive.
184 semanage module can also be used to enable/disable/install/remove pol‐
186 icy modules.
187 semanage boolean can also be used to manipulate the booleans
189 system-config-selinux is a GUI tool available to customize SELinux pol‐
192 icy settings.
