NAME

6       lttng_sessiond_selinux   -  Security  Enhanced  Linux  Policy  for  the
7       lttng_sessiond processes
8

DESCRIPTION

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

ENTRYPOINTS

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

PROCESS TYPES

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.

51

BOOLEANS

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. Disabled 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. Disabled by default.
91
92       setsebool -P nscd_use_shm 1

MANAGED FILES

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.

103
104            /etc/cluster(/.*)?

FILE CONTEXTS

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

COMMANDS

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.
