6 lttng_sessiond_selinux - Security Enhanced Linux Policy for the
7 lttng_sessiond processes
8
10 Security-Enhanced Linux secures the lttng_sessiond processes via flexi‐
11 ble mandatory access control.
12
13 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
17 For example:
18
19 ps -eZ | grep lttng_sessiond_t
20
21
22
24 The lttng_sessiond_t SELinux type can be entered via the lttng_ses‐
25 siond_exec_t file type.
26
27 The default entrypoint paths for the lttng_sessiond_t domain are the
28 following:
29
30 /usr/bin/lttng-sessiond
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 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
42 The following process types are defined for lttng_sessiond:
43
44 lttng_sessiond_t
45
46 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
51
53 SELinux policy is customizable based on least access required.
54 lttng_sessiond policy is extremely flexible and has several booleans
55 that allow you to manipulate the policy and run lttng_sessiond with the
56 tightest access possible.
57
58
59
60 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
63 setsebool -P fips_mode 1
64
65
66
67 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69
70 setsebool -P nis_enabled 1
71
72
73
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.

124 SELinux requires files to have an extended attribute to define the file
125 type.
126
127 You can see the context of a file using the -Z option to ls
128
129 Policy governs the access confined processes have to these files.
130 SELinux lttng_sessiond policy is very flexible allowing users to setup
131 their lttng_sessiond processes in as secure a method as possible.
132
133 STANDARD FILE CONTEXT
134
135 SELinux defines the file context types for the lttng_sessiond, if you
136 wanted to store files with these types in a diffent paths, you need to
137 execute the semanage command to sepecify alternate labeling and then
138 use restorecon to put the labels on disk.
139
140 semanage fcontext -a -t lttng_sessiond_unit_file_t '/srv/mylttng_ses‐
141 siond_content(/.*)?'
142 restorecon -R -v /srv/mylttng_sessiond_content
143
144 Note: SELinux often uses regular expressions to specify labels that
145 match multiple files.
146
147 The following file types are defined for lttng_sessiond:
148
149
150
151 lttng_sessiond_exec_t
152
153 - Set files with the lttng_sessiond_exec_t type, if you want to transi‐
154 tion an executable to the lttng_sessiond_t domain.
155
156
157
158 lttng_sessiond_tmpfs_t
159
160 - Set files with the lttng_sessiond_tmpfs_t type, if you want to store
161 lttng sessiond files on a tmpfs file system.
162
163
164
165 lttng_sessiond_unit_file_t
166
167 - Set files with the lttng_sessiond_unit_file_t type, if you want to
168 treat the files as lttng sessiond unit content.
169
170
171
172 lttng_sessiond_var_run_t
173
174 - Set files with the lttng_sessiond_var_run_t type, if you want to
175 store the lttng sessiond files under the /run or /var/run directory.
176
177
178
179 Note: File context can be temporarily modified with the chcon command.
180 If you want to permanently change the file context you need to use the
181 semanage fcontext command. This will modify the SELinux labeling data‐
182 base. You will need to use restorecon to apply the labels.
183
184
186 semanage fcontext can also be used to manipulate default file context
187 mappings.
188
189 semanage permissive can also be used to manipulate whether or not a
190 process type is permissive.
191
192 semanage module can also be used to enable/disable/install/remove pol‐
193 icy modules.
194
195 semanage boolean can also be used to manipulate the booleans
196
197
198 system-config-selinux is a GUI tool available to customize SELinux pol‐
199 icy settings.
