6 brltty_selinux - Security Enhanced Linux Policy for the brltty pro‐
7 cesses
8
10 Security-Enhanced Linux secures the brltty processes via flexible
11 mandatory access control.
12 The brltty processes execute with the brltty_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16 For example:
18 ps -eZ | grep brltty_t
20
24 The brltty_t SELinux type can be entered via the brltty_exec_t file
25 type.
26 The default entrypoint paths for the brltty_t domain are the following:
28 /usr/bin/brltty
30
32 SELinux defines process types (domains) for each process running on the
33 system
34 You can see the context of a process using the -Z option to ps
36 Policy governs the access confined processes have to files. SELinux
38 brltty policy is very flexible allowing users to setup their brltty
39 processes in as secure a method as possible.
40 The following process types are defined for brltty:
42 brltty_t
44 Note: semanage permissive -a brltty_t can be used to make the process
46 type brltty_t permissive. SELinux does not deny access to permissive
47 process types, but the AVC (SELinux denials) messages are still gener‐
48 ated.
49
52 SELinux policy is customizable based on least access required. brltty
53 policy is extremely flexible and has several booleans that allow you to
54 manipulate the policy and run brltty with the tightest access possible.
55 If you want to allow users to resolve user passwd entries directly from
59 ldap rather then using a sssd server, you must turn on the authlo‐
60 gin_nsswitch_use_ldap boolean. Disabled by default.
61 setsebool -P authlogin_nsswitch_use_ldap 1
63 If you want to allow all domains to execute in fips_mode, you must turn
67 on the fips_mode boolean. Enabled by default.
68 setsebool -P fips_mode 1
70 If you want to allow confined applications to run with kerberos, you
74 must turn on the kerberos_enabled boolean. Enabled by default.
75 setsebool -P kerberos_enabled 1
77 If you want to allow system to run with NIS, you must turn on the
81 nis_enabled boolean. Disabled by default.
82 setsebool -P nis_enabled 1
84 If you want to allow confined applications to use nscd shared memory,
88 you must turn on the nscd_use_shm boolean. Disabled by default.
89 setsebool -P nscd_use_shm 1

95 The SELinux process type brltty_t can manage files labeled with the
96 following file types. The paths listed are the default paths for these
97 file types. Note the processes UID still need to have DAC permissions.

148 SELinux requires files to have an extended attribute to define the file
149 type.
150 You can see the context of a file using the -Z option to ls
152 Policy governs the access confined processes have to these files.
154 SELinux brltty policy is very flexible allowing users to setup their
155 brltty processes in as secure a method as possible.
156 STANDARD FILE CONTEXT
158 SELinux defines the file context types for the brltty, if you wanted to
160 store files with these types in a diffent paths, you need to execute
161 the semanage command to sepecify alternate labeling and then use
162 restorecon to put the labels on disk.
163 semanage fcontext -a -t brltty_unit_file_t '/srv/mybrltty_con‐
165 tent(/.*)?'
166 restorecon -R -v /srv/mybrltty_content
167 Note: SELinux often uses regular expressions to specify labels that
169 match multiple files.
170 The following file types are defined for brltty:
172 brltty_exec_t
176 - Set files with the brltty_exec_t type, if you want to transition an
178 executable to the brltty_t domain.
179 brltty_log_t
183 - Set files with the brltty_log_t type, if you want to treat the data
185 as brltty log data, usually stored under the /var/log directory.
186 brltty_unit_file_t
190 - Set files with the brltty_unit_file_t type, if you want to treat the
192 files as brltty unit content.
193 brltty_var_lib_t
197 - Set files with the brltty_var_lib_t type, if you want to store the
199 brltty files under the /var/lib directory.
200 brltty_var_run_t
204 - Set files with the brltty_var_run_t type, if you want to store the
206 brltty files under the /run or /var/run directory.
207 Note: File context can be temporarily modified with the chcon command.
211 If you want to permanently change the file context you need to use the
212 semanage fcontext command. This will modify the SELinux labeling data‐
213 base. You will need to use restorecon to apply the labels.
214
217 semanage fcontext can also be used to manipulate default file context
218 mappings.
219 semanage permissive can also be used to manipulate whether or not a
221 process type is permissive.
222 semanage module can also be used to enable/disable/install/remove pol‐
224 icy modules.
225 semanage boolean can also be used to manipulate the booleans
227 system-config-selinux is a GUI tool available to customize SELinux pol‐
230 icy settings.
