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 users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63
64 setsebool -P authlogin_nsswitch_use_ldap 1
65
66
67
68 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
71 setsebool -P fips_mode 1
72
73
74
75 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Enabled by default.
77
78 setsebool -P kerberos_enabled 1
79
80
81
82 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84
85 setsebool -P nis_enabled 1
86
87
88
89 If you want to allow confined applications to use nscd shared memory,
90 you must turn on the nscd_use_shm boolean. Enabled by default.
91
92 setsebool -P nscd_use_shm 1
93
94
95
97 The SELinux process type lttng_sessiond_t can manage files labeled with
98 the following file types. The paths listed are the default paths for
99 these file types. Note the processes UID still need to have DAC per‐
100 missions.

146 SELinux requires files to have an extended attribute to define the file
147 type.
148
149 You can see the context of a file using the -Z option to ls
150
151 Policy governs the access confined processes have to these files.
152 SELinux lttng_sessiond policy is very flexible allowing users to setup
153 their lttng_sessiond processes in as secure a method as possible.
154
155 STANDARD FILE CONTEXT
156
157 SELinux defines the file context types for the lttng_sessiond, if you
158 wanted to store files with these types in a diffent paths, you need to
159 execute the semanage command to sepecify alternate labeling and then
160 use restorecon to put the labels on disk.
161
162 semanage fcontext -a -t lttng_sessiond_unit_file_t '/srv/mylttng_ses‐
163 siond_content(/.*)?'
164 restorecon -R -v /srv/mylttng_sessiond_content
165
166 Note: SELinux often uses regular expressions to specify labels that
167 match multiple files.
168
169 The following file types are defined for lttng_sessiond:
170
171
172
173 lttng_sessiond_exec_t
174
175 - Set files with the lttng_sessiond_exec_t type, if you want to transi‐
176 tion an executable to the lttng_sessiond_t domain.
177
178
179
180 lttng_sessiond_tmpfs_t
181
182 - Set files with the lttng_sessiond_tmpfs_t type, if you want to store
183 lttng sessiond files on a tmpfs file system.
184
185
186
187 lttng_sessiond_unit_file_t
188
189 - Set files with the lttng_sessiond_unit_file_t type, if you want to
190 treat the files as lttng sessiond unit content.
191
192
193
194 lttng_sessiond_var_run_t
195
196 - Set files with the lttng_sessiond_var_run_t type, if you want to
197 store the lttng sessiond files under the /run or /var/run directory.
198
199
200
201 Note: File context can be temporarily modified with the chcon command.
202 If you want to permanently change the file context you need to use the
203 semanage fcontext command. This will modify the SELinux labeling data‐
204 base. You will need to use restorecon to apply the labels.
205
206
208 semanage fcontext can also be used to manipulate default file context
209 mappings.
210
211 semanage permissive can also be used to manipulate whether or not a
212 process type is permissive.
213
214 semanage module can also be used to enable/disable/install/remove pol‐
215 icy modules.
216
217 semanage boolean can also be used to manipulate the booleans
218
219
220 system-config-selinux is a GUI tool available to customize SELinux pol‐
221 icy settings.
