6 gssd_selinux - Security Enhanced Linux Policy for the gssd processes
7
9 Security-Enhanced Linux secures the gssd processes via flexible manda‐
10 tory access control.
11 The gssd processes execute with the gssd_t SELinux type. You can check
13 if you have these processes running by executing the ps command with
14 the -Z qualifier.
15 For example:
17 ps -eZ | grep gssd_t
19
23 The gssd_t SELinux type can be entered via the gssd_exec_t file type.
24 The default entrypoint paths for the gssd_t domain are the following:
26 /usr/sbin/rpc.gssd, /usr/sbin/rpc.svcgssd
28
30 SELinux defines process types (domains) for each process running on the
31 system
32 You can see the context of a process using the -Z option to ps
34 Policy governs the access confined processes have to files. SELinux
36 gssd policy is very flexible allowing users to setup their gssd pro‐
37 cesses in as secure a method as possible.
38 The following process types are defined for gssd:
40 gssd_t
42 Note: semanage permissive -a gssd_t can be used to make the process
44 type gssd_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
50 SELinux policy is customizable based on least access required. gssd
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run gssd with the tightest access possible.
53 If you want to allow gssd to list tmp directories and read the kerberos
57 credential cache, you must turn on the gssd_read_tmp boolean. Enabled
58 by default.
59 setsebool -P gssd_read_tmp 1
61 If you want to allow all domains to execute in fips_mode, you must turn
65 on the fips_mode boolean. Enabled by default.
66 setsebool -P fips_mode 1
68 If you want to allow confined applications to run with kerberos, you
72 must turn on the kerberos_enabled boolean. Enabled by default.
73 setsebool -P kerberos_enabled 1
75
79 The SELinux process type gssd_t can manage files labeled with the fol‐
80 lowing file types. The paths listed are the default paths for these
81 file types. Note the processes UID still need to have DAC permissions.

166 SELinux requires files to have an extended attribute to define the file
167 type.
168 You can see the context of a file using the -Z option to ls
170 Policy governs the access confined processes have to these files.
172 SELinux gssd policy is very flexible allowing users to setup their gssd
173 processes in as secure a method as possible.
174 STANDARD FILE CONTEXT
176 SELinux defines the file context types for the gssd, if you wanted to
178 store files with these types in a diffent paths, you need to execute
179 the semanage command to specify alternate labeling and then use re‐
180 storecon to put the labels on disk.
181 semanage fcontext -a -t gssd_tmp_t '/srv/mygssd_content(/.*)?'
183 restorecon -R -v /srv/mygssd_content
184 Note: SELinux often uses regular expressions to specify labels that
186 match multiple files.
187 The following file types are defined for gssd:
189 gssd_exec_t
193 - Set files with the gssd_exec_t type, if you want to transition an ex‐
195 ecutable to the gssd_t domain.
196 Paths:
199 /usr/sbin/rpc.gssd, /usr/sbin/rpc.svcgssd
200 gssd_keytab_t
203 - Set files with the gssd_keytab_t type, if you want to treat the files
205 as kerberos keytab files.
206 gssd_tmp_t
210 - Set files with the gssd_tmp_t type, if you want to store gssd tempo‐
212 rary files in the /tmp directories.
213 Note: File context can be temporarily modified with the chcon command.
217 If you want to permanently change the file context you need to use the
218 semanage fcontext command. This will modify the SELinux labeling data‐
219 base. You will need to use restorecon to apply the labels.
220
223 semanage fcontext can also be used to manipulate default file context
224 mappings.
225 semanage permissive can also be used to manipulate whether or not a
227 process type is permissive.
228 semanage module can also be used to enable/disable/install/remove pol‐
230 icy modules.
231 semanage boolean can also be used to manipulate the booleans
233 system-config-selinux is a GUI tool available to customize SELinux pol‐
236 icy settings.
