6 vhostmd_selinux - Security Enhanced Linux Policy for the vhostmd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the vhostmd processes via flexible
11 mandatory access control.
12 The vhostmd processes execute with the vhostmd_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 vhostmd_t
20
24 The vhostmd_t SELinux type can be entered via the vhostmd_exec_t file
25 type.
26 The default entrypoint paths for the vhostmd_t domain are the follow‐
28 ing:
29 /usr/sbin/vhostmd
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 vhostmd policy is very flexible allowing users to setup their vhostmd
40 processes in as secure a method as possible.
41 The following process types are defined for vhostmd:
43 vhostmd_t
45 Note: semanage permissive -a vhostmd_t can be used to make the process
47 type vhostmd_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
53 SELinux policy is customizable based on least access required. vhostmd
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run vhostmd with the tightest access possi‐
56 ble.
57 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 setsebool -P authlogin_nsswitch_use_ldap 1
65 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 setsebool -P fips_mode 1
72 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Enabled by default.
77 setsebool -P kerberos_enabled 1
79 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84 setsebool -P nis_enabled 1
86 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 setsebool -P nscd_use_shm 1

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

156 SELinux requires files to have an extended attribute to define the file
157 type.
158 You can see the context of a file using the -Z option to ls
160 Policy governs the access confined processes have to these files.
162 SELinux vhostmd policy is very flexible allowing users to setup their
163 vhostmd processes in as secure a method as possible.
164 STANDARD FILE CONTEXT
166 SELinux defines the file context types for the vhostmd, if you wanted
168 to store files with these types in a diffent paths, you need to execute
169 the semanage command to sepecify alternate labeling and then use
170 restorecon to put the labels on disk.
171 semanage fcontext -a -t vhostmd_var_run_t '/srv/myvhostmd_con‐
173 tent(/.*)?'
174 restorecon -R -v /srv/myvhostmd_content
175 Note: SELinux often uses regular expressions to specify labels that
177 match multiple files.
178 The following file types are defined for vhostmd:
180 vhostmd_exec_t
184 - Set files with the vhostmd_exec_t type, if you want to transition an
186 executable to the vhostmd_t domain.
187 vhostmd_initrc_exec_t
191 - Set files with the vhostmd_initrc_exec_t type, if you want to transi‐
193 tion an executable to the vhostmd_initrc_t domain.
194 vhostmd_tmpfs_t
198 - Set files with the vhostmd_tmpfs_t type, if you want to store vhostmd
200 files on a tmpfs file system.
201 vhostmd_var_run_t
205 - Set files with the vhostmd_var_run_t type, if you want to store the
207 vhostmd files under the /run or /var/run directory.
208 Note: File context can be temporarily modified with the chcon command.
212 If you want to permanently change the file context you need to use the
213 semanage fcontext command. This will modify the SELinux labeling data‐
214 base. You will need to use restorecon to apply the labels.
215
218 semanage fcontext can also be used to manipulate default file context
219 mappings.
220 semanage permissive can also be used to manipulate whether or not a
222 process type is permissive.
223 semanage module can also be used to enable/disable/install/remove pol‐
225 icy modules.
226 semanage boolean can also be used to manipulate the booleans
228 system-config-selinux is a GUI tool available to customize SELinux pol‐
231 icy settings.
