Security-Enhanced Linux secures the cvs processes via flexible mandatory access control.
If you want to allow cvs daemon to read shadow, you must turn on the cvs_read_shadow boolean.
setsebool -P cvs_read_shadow 1
If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd serve for the cvs_t, you must turn on the authlogin_nsswitch_use_ldap boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the cvs_t, you must turn on the kerberos_enabled boolean.
setsebool -P kerberos_enabled 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 cvs policy is very flexible allowing users to setup their cvs processes in as secure a method as possible.
The following file types are defined for cvs:
cvs_data_t
- Set files with the cvs_data_t type, if you want to treat the files as cvs content.
cvs_exec_t
- Set files with the cvs_exec_t type, if you want to transition an executable to the cvs_t domain.
cvs_initrc_exec_t
- Set files with the cvs_initrc_exec_t type, if you want to transition an executable to the cvs_initrc_t domain.
cvs_keytab_t
- Set files with the cvs_keytab_t type, if you want to treat the files as kerberos keytab files.
cvs_tmp_t
- Set files with the cvs_tmp_t type, if you want to store cvs temporary files in the /tmp directories.
cvs_var_run_t
- Set files with the cvs_var_run_t type, if you want to store the cvs 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 cvs policy is very flexible allowing users to setup their cvs processes in as secure a method as possible.
The following port types are defined for cvs:
Default Defined Ports: tcp 2401 udp 2401
You can see the context of a process using the -Z option to psP Policy governs the access confined processes have to files. SELinux cvs policy is very flexible allowing users to setup their cvs processes in as secure a method as possible.
The following process types are defined for cvs:
cvs_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 cvs_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.
cvs_data_t
/opt/cvs(/.*)?
/var/cvs(/.*)?
cvs_tmp_t
cvs_var_run_t
faillog_t
