6 lttng_sessiond_selinux - Security Enhanced Linux Policy for the lt‐
7 tng_sessiond processes
8
10 Security-Enhanced Linux secures the lttng_sessiond processes via flexi‐
11 ble mandatory access control.
12 The lttng_sessiond processes execute with the lttng_sessiond_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 lttng_sessiond_t
20
24 The lttng_sessiond_t SELinux type can be entered via the lttng_ses‐
25 siond_exec_t file type.
26 The default entrypoint paths for the lttng_sessiond_t domain are the
28 following:
29 /usr/bin/lttng-sessiond
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 lttng_sessiond policy is very flexible allowing users to setup their
40 lttng_sessiond processes in as secure a method as possible.
41 The following process types are defined for lttng_sessiond:
43 lttng_sessiond_t
45 Note: semanage permissive -a lttng_sessiond_t can be used to make the
47 process type lttng_sessiond_t permissive. SELinux does not deny access
48 to permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required. lt‐
54 tng_sessiond policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run lttng_sessiond with the
56 tightest access possible.
57 If you want to dontaudit all daemons scheduling requests (setsched,
61 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
62 Enabled by default.
63 setsebool -P daemons_dontaudit_scheduling 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 system to run with NIS, you must turn on the
76 nis_enabled boolean. Disabled by default.
77 setsebool -P nis_enabled 1

83 The SELinux process type lttng_sessiond_t can manage files labeled with
84 the following file types. The paths listed are the default paths for
85 these file types. Note the processes UID still need to have DAC per‐
86 missions.

147 SELinux requires files to have an extended attribute to define the file
148 type.
149 You can see the context of a file using the -Z option to ls
151 Policy governs the access confined processes have to these files.
153 SELinux lttng_sessiond policy is very flexible allowing users to setup
154 their lttng_sessiond processes in as secure a method as possible.
155 STANDARD FILE CONTEXT
157 SELinux defines the file context types for the lttng_sessiond, if you
159 wanted to store files with these types in a different paths, you need
160 to execute the semanage command to specify alternate labeling and then
161 use restorecon to put the labels on disk.
162 semanage fcontext -a -t lttng_sessiond_exec_t '/srv/lttng_sessiond/con‐
164 tent(/.*)?'
165 restorecon -R -v /srv/mylttng_sessiond_content
166 Note: SELinux often uses regular expressions to specify labels that
168 match multiple files.
169 The following file types are defined for lttng_sessiond:
171 lttng_sessiond_exec_t
175 - Set files with the lttng_sessiond_exec_t type, if you want to transi‐
177 tion an executable to the lttng_sessiond_t domain.
178 lttng_sessiond_tmpfs_t
182 - Set files with the lttng_sessiond_tmpfs_t type, if you want to store
184 lttng sessiond files on a tmpfs file system.
185 lttng_sessiond_unit_file_t
189 - Set files with the lttng_sessiond_unit_file_t type, if you want to
191 treat the files as lttng sessiond unit content.
192 lttng_sessiond_var_run_t
196 - Set files with the lttng_sessiond_var_run_t type, if you want to
198 store the lttng sessiond files under the /run or /var/run directory.
199 Note: File context can be temporarily modified with the chcon command.
203 If you want to permanently change the file context you need to use the
204 semanage fcontext command. This will modify the SELinux labeling data‐
205 base. You will need to use restorecon to apply the labels.
206
209 semanage fcontext can also be used to manipulate default file context
210 mappings.
211 semanage permissive can also be used to manipulate whether or not a
213 process type is permissive.
214 semanage module can also be used to enable/disable/install/remove pol‐
216 icy modules.
217 semanage boolean can also be used to manipulate the booleans
219 system-config-selinux is a GUI tool available to customize SELinux pol‐
222 icy settings.
