Security-Enhanced Linux secures the zebra processes via flexible mandatory access control.
If you want to allow zebra daemon to write it configuration files, you must turn on the zebra_write_config boolean.
setsebool -P zebra_write_config 1
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 zebra policy is very flexible allowing users to setup their zebra processes in as secure a method as possible.
The following file types are defined for zebra:
zebra_conf_t
- Set files with the zebra_conf_t type, if you want to treat the files as zebra configuration data, usually stored under the /etc directory.
zebra_exec_t
- Set files with the zebra_exec_t type, if you want to transition an executable to the zebra_t domain.
zebra_initrc_exec_t
- Set files with the zebra_initrc_exec_t type, if you want to transition an executable to the zebra_initrc_t domain.
zebra_log_t
- Set files with the zebra_log_t type, if you want to treat the data as zebra log data, usually stored under the /var/log directory.
zebra_tmp_t
- Set files with the zebra_tmp_t type, if you want to store zebra temporary files in the /tmp directories.
zebra_var_run_t
- Set files with the zebra_var_run_t type, if you want to store the zebra files under the /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.
You can see the types associated with a port by using the following command:
semanage port -l
Policy governs the access confined processes have to these ports. SELinux zebra policy is very flexible allowing users to setup their zebra processes in as secure a method as possible.
The following port types are defined for zebra:
Default Defined Ports: tcp 2600-2604,2606 udp 2600-2604,2606
You can see the context of a process using the -Z option to psP Policy governs the access confined processes have to files. SELinux zebra policy is very flexible allowing users to setup their zebra processes in as secure a method as possible.
The following process types are defined for zebra:
zebra_t
Note: semanage permissive -a PROCESS_TYPE can be used to make a process type permissive. Permissive process types are not denied access by SELinux. AVC messages will still be generated.
The SELinux user type zebra_t can manage files labeled with the following file types. The paths listed are the default paths for these file ty
