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 all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62 setsebool -P fips_mode 1
64 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69 setsebool -P nis_enabled 1
71
75 The SELinux process type vhostmd_t can manage files labeled with the
76 following file types. The paths listed are the default paths for these
77 file types. Note the processes UID still need to have DAC permissions.

134 SELinux requires files to have an extended attribute to define the file
135 type.
136 You can see the context of a file using the -Z option to ls
138 Policy governs the access confined processes have to these files.
140 SELinux vhostmd policy is very flexible allowing users to setup their
141 vhostmd processes in as secure a method as possible.
142 STANDARD FILE CONTEXT
144 SELinux defines the file context types for the vhostmd, if you wanted
146 to store files with these types in a diffent paths, you need to execute
147 the semanage command to sepecify alternate labeling and then use
148 restorecon to put the labels on disk.
149 semanage fcontext -a -t vhostmd_var_run_t '/srv/myvhostmd_con‐
151 tent(/.*)?'
152 restorecon -R -v /srv/myvhostmd_content
153 Note: SELinux often uses regular expressions to specify labels that
155 match multiple files.
156 The following file types are defined for vhostmd:
158 vhostmd_exec_t
162 - Set files with the vhostmd_exec_t type, if you want to transition an
164 executable to the vhostmd_t domain.
165 vhostmd_initrc_exec_t
169 - Set files with the vhostmd_initrc_exec_t type, if you want to transi‐
171 tion an executable to the vhostmd_initrc_t domain.
172 vhostmd_tmpfs_t
176 - Set files with the vhostmd_tmpfs_t type, if you want to store vhostmd
178 files on a tmpfs file system.
179 vhostmd_var_run_t
183 - Set files with the vhostmd_var_run_t type, if you want to store the
185 vhostmd files under the /run or /var/run directory.
186 Note: File context can be temporarily modified with the chcon command.
190 If you want to permanently change the file context you need to use the
191 semanage fcontext command. This will modify the SELinux labeling data‐
192 base. You will need to use restorecon to apply the labels.
193
196 semanage fcontext can also be used to manipulate default file context
197 mappings.
198 semanage permissive can also be used to manipulate whether or not a
200 process type is permissive.
201 semanage module can also be used to enable/disable/install/remove pol‐
203 icy modules.
204 semanage boolean can also be used to manipulate the booleans
206 system-config-selinux is a GUI tool available to customize SELinux pol‐
209 icy settings.
