Security-Enhanced Linux secures the xenconsoled processes via flexible mandatory access control.
The xenconsoled processes execute with the xenconsoled_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.
For example:
ps -eZ | grep xenconsoled_t
The xenconsoled_t SELinux type can be entered via the xenconsoled_exec_t file type.
The default entrypoint paths for the xenconsoled_t domain are the following:
You can see the context of a process using the -Z option to psP Policy governs the access confined processes have to files. SELinux xenconsoled policy is very flexible allowing users to setup their xenconsoled processes in as secure a method as possible.
The following process types are defined for xenconsoled:
xenconsoled_t
Note: semanage permissive -a xenconsoled_t can be used to make the process type xenconsoled_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.
If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.
setsebool -P fips_mode 1
The SELinux process type xenconsoled_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions.

You can see the context of a file using the -Z option to lsP Policy governs the access confined processes have to these files. SELinux xenconsoled policy is very flexible allowing users to setup their xenconsoled processes in as secure a method as possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the xenconsoled, if you wanted to store files with these types in a diffent paths, you need to execute the semanage command to sepecify alternate labeling and then use restorecon to put the labels on disk.
semanage fcontext -a -t xenconsoled_var_run_t '/srv/myxenconsoled_content(/.*)?'
restorecon -R -v /srv/myxenconsoled_content
Note: SELinux often uses regular expressions to specify labels that match multiple files.
The following file types are defined for xenconsoled:
xenconsoled_exec_t
- Set files with the xenconsoled_exec_t type, if you want to transition an executable to the xenconsoled_t domain.
xenconsoled_var_run_t
- Set files with the xenconsoled_var_run_t type, if you want to store the xenconsoled files under the /run or /var/run directory.
Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels.
semanage permissive can also be used to manipulate whether or not a process type is permissive.
semanage module can also be used to enable/disable/install/remove policy modules.
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux policy settings.
