6 opensm_selinux - Security Enhanced Linux Policy for the opensm pro‐
7 cesses
8
10 Security-Enhanced Linux secures the opensm processes via flexible
11 mandatory access control.
12 The opensm processes execute with the opensm_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16 For example:
18 ps -eZ | grep opensm_t
20
24 The opensm_t SELinux type can be entered via the opensm_exec_t file
25 type.
26 The default entrypoint paths for the opensm_t domain are the following:
28 /usr/libexec/opensm-launch
30
32 SELinux defines process types (domains) for each process running on the
33 system
34 You can see the context of a process using the -Z option to ps
36 Policy governs the access confined processes have to files. SELinux
38 opensm policy is very flexible allowing users to setup their opensm
39 processes in as secure a method as possible.
40 The following process types are defined for opensm:
42 opensm_t
44 Note: semanage permissive -a opensm_t can be used to make the process
46 type opensm_t permissive. SELinux does not deny access to permissive
47 process types, but the AVC (SELinux denials) messages are still gener‐
48 ated.
49
52 SELinux policy is customizable based on least access required. opensm
53 policy is extremely flexible and has several booleans that allow you to
54 manipulate the policy and run opensm with the tightest access possible.
55 If you want to allow users to resolve user passwd entries directly from
59 ldap rather then using a sssd server, you must turn on the authlo‐
60 gin_nsswitch_use_ldap boolean. Disabled by default.
61 setsebool -P authlogin_nsswitch_use_ldap 1
63 If you want to allow all domains to execute in fips_mode, you must turn
67 on the fips_mode boolean. Enabled by default.
68 setsebool -P fips_mode 1
70 If you want to allow confined applications to run with kerberos, you
74 must turn on the kerberos_enabled boolean. Enabled by default.
75 setsebool -P kerberos_enabled 1
77 If you want to allow system to run with NIS, you must turn on the
81 nis_enabled boolean. Disabled by default.
82 setsebool -P nis_enabled 1
84 If you want to allow confined applications to use nscd shared memory,
88 you must turn on the nscd_use_shm boolean. Enabled by default.
89 setsebool -P nscd_use_shm 1

95 The SELinux process type opensm_t can manage files labeled with the
96 following file types. The paths listed are the default paths for these
97 file types. Note the processes UID still need to have DAC permissions.

144 SELinux requires files to have an extended attribute to define the file
145 type.
146 You can see the context of a file using the -Z option to ls
148 Policy governs the access confined processes have to these files.
150 SELinux opensm policy is very flexible allowing users to setup their
151 opensm processes in as secure a method as possible.
152 STANDARD FILE CONTEXT
154 SELinux defines the file context types for the opensm, if you wanted to
156 store files with these types in a diffent paths, you need to execute
157 the semanage command to sepecify alternate labeling and then use
158 restorecon to put the labels on disk.
159 semanage fcontext -a -t opensm_unit_file_t '/srv/myopensm_con‐
161 tent(/.*)?'
162 restorecon -R -v /srv/myopensm_content
163 Note: SELinux often uses regular expressions to specify labels that
165 match multiple files.
166 The following file types are defined for opensm:
168 opensm_cache_t
172 - Set files with the opensm_cache_t type, if you want to store the
174 files under the /var/cache directory.
175 opensm_exec_t
179 - Set files with the opensm_exec_t type, if you want to transition an
181 executable to the opensm_t domain.
182 opensm_log_t
186 - Set files with the opensm_log_t type, if you want to treat the data
188 as opensm log data, usually stored under the /var/log directory.
189 opensm_unit_file_t
193 - Set files with the opensm_unit_file_t type, if you want to treat the
195 files as opensm unit content.
196 Note: File context can be temporarily modified with the chcon command.
200 If you want to permanently change the file context you need to use the
201 semanage fcontext command. This will modify the SELinux labeling data‐
202 base. You will need to use restorecon to apply the labels.
203
206 semanage fcontext can also be used to manipulate default file context
207 mappings.
208 semanage permissive can also be used to manipulate whether or not a
210 process type is permissive.
211 semanage module can also be used to enable/disable/install/remove pol‐
213 icy modules.
214 semanage boolean can also be used to manipulate the booleans
216 system-config-selinux is a GUI tool available to customize SELinux pol‐
219 icy settings.
