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 deny all system processes and Linux users to use blue‐
59 tooth wireless technology, you must turn on the deny_bluetooth boolean.
60 Enabled by default.
61 setsebool -P deny_bluetooth 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
74 The SELinux process type brltty_t can manage files labeled with the
75 following file types. The paths listed are the default paths for these
76 file types. Note the processes UID still need to have DAC permissions.

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 brltty policy is very flexible allowing users to setup their
150 brltty processes in as secure a method as possible.
151 STANDARD FILE CONTEXT
153 SELinux defines the file context types for the brltty, if you wanted to
155 store files with these types in a diffent paths, you need to execute
156 the semanage command to specify alternate labeling and then use re‐
157 storecon to put the labels on disk.
158 semanage fcontext -a -t brltty_unit_file_t '/srv/mybrltty_con‐
160 tent(/.*)?'
161 restorecon -R -v /srv/mybrltty_content
162 Note: SELinux often uses regular expressions to specify labels that
164 match multiple files.
165 The following file types are defined for brltty:
167 brltty_exec_t
171 - Set files with the brltty_exec_t type, if you want to transition an
173 executable to the brltty_t domain.
174 brltty_log_t
178 - Set files with the brltty_log_t type, if you want to treat the data
180 as brltty log data, usually stored under the /var/log directory.
181 brltty_unit_file_t
185 - Set files with the brltty_unit_file_t type, if you want to treat the
187 files as brltty unit content.
188 brltty_var_lib_t
192 - Set files with the brltty_var_lib_t type, if you want to store the
194 brltty files under the /var/lib directory.
195 Paths:
198 /var/lib/BrlAPI(/.*)?, /var/lib/brltty(/.*)?
199 brltty_var_run_t
202 - Set files with the brltty_var_run_t type, if you want to store the
204 brltty files under the /run or /var/run directory.
205 Note: File context can be temporarily modified with the chcon command.
209 If you want to permanently change the file context you need to use the
210 semanage fcontext command. This will modify the SELinux labeling data‐
211 base. You will need to use restorecon to apply the labels.
212
215 semanage fcontext can also be used to manipulate default file context
216 mappings.
217 semanage permissive can also be used to manipulate whether or not a
219 process type is permissive.
220 semanage module can also be used to enable/disable/install/remove pol‐
222 icy modules.
223 semanage boolean can also be used to manipulate the booleans
225 system-config-selinux is a GUI tool available to customize SELinux pol‐
228 icy settings.
