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 allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62 setsebool -P fips_mode 1
64 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69 setsebool -P nis_enabled 1
71
75 The SELinux process type lttng_sessiond_t can manage files labeled with
76 the following file types. The paths listed are the default paths for
77 these file types. Note the processes UID still need to have DAC per‐
78 missions.

139 SELinux requires files to have an extended attribute to define the file
140 type.
141 You can see the context of a file using the -Z option to ls
143 Policy governs the access confined processes have to these files.
145 SELinux lttng_sessiond policy is very flexible allowing users to setup
146 their lttng_sessiond processes in as secure a method as possible.
147 STANDARD FILE CONTEXT
149 SELinux defines the file context types for the lttng_sessiond, if you
151 wanted to store files with these types in a diffent paths, you need to
152 execute the semanage command to sepecify alternate labeling and then
153 use restorecon to put the labels on disk.
154 semanage fcontext -a -t lttng_sessiond_unit_file_t '/srv/mylttng_ses‐
156 siond_content(/.*)?'
157 restorecon -R -v /srv/mylttng_sessiond_content
158 Note: SELinux often uses regular expressions to specify labels that
160 match multiple files.
161 The following file types are defined for lttng_sessiond:
163 lttng_sessiond_exec_t
167 - Set files with the lttng_sessiond_exec_t type, if you want to transi‐
169 tion an executable to the lttng_sessiond_t domain.
170 lttng_sessiond_tmpfs_t
174 - Set files with the lttng_sessiond_tmpfs_t type, if you want to store
176 lttng sessiond files on a tmpfs file system.
177 lttng_sessiond_unit_file_t
181 - Set files with the lttng_sessiond_unit_file_t type, if you want to
183 treat the files as lttng sessiond unit content.
184 lttng_sessiond_var_run_t
188 - Set files with the lttng_sessiond_var_run_t type, if you want to
190 store the lttng sessiond files under the /run or /var/run directory.
191 Note: File context can be temporarily modified with the chcon command.
195 If you want to permanently change the file context you need to use the
196 semanage fcontext command. This will modify the SELinux labeling data‐
197 base. You will need to use restorecon to apply the labels.
198
201 semanage fcontext can also be used to manipulate default file context
202 mappings.
203 semanage permissive can also be used to manipulate whether or not a
205 process type is permissive.
206 semanage module can also be used to enable/disable/install/remove pol‐
208 icy modules.
209 semanage boolean can also be used to manipulate the booleans
211 system-config-selinux is a GUI tool available to customize SELinux pol‐
214 icy settings.
