Security-Enhanced Linux secures the mock processes via flexible mandatory access control.
If you want to allow mock to read files in home directories, you must turn on the mock_enable_homedirs boolean.
setsebool -P mock_enable_homedirs 1
If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd serve for the mock_t, mock_build_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 mock_t, mock_build_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 mock policy is very flexible allowing users to setup their mock processes in as secure a method as possible.
The following file types are defined for mock:
mock_build_exec_t
- Set files with the mock_build_exec_t type, if you want to transition an executable to the mock_build_t domain.
mock_cache_t
- Set files with the mock_cache_t type, if you want to store the files under the /var/cache directory.
mock_etc_t
- Set files with the mock_etc_t type, if you want to store mock files in the /etc directories.
mock_exec_t
- Set files with the mock_exec_t type, if you want to transition an executable to the mock_t domain.
mock_tmp_t
- Set files with the mock_tmp_t type, if you want to store mock temporary files in the /tmp directories.
mock_var_lib_t
- Set files with the mock_var_lib_t type, if you want to store the mock files under the /var/lib 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 context of a process using the -Z option to psP Policy governs the access confined processes have to files. SELinux mock policy is very flexible allowing users to setup their mock processes in as secure a method as possible.
The following process types are defined for mock:
mock_t, mock_build_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 mock_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.
mock_cache_t
/var/cache/mock(/.*)?
mock_tmp_t
mock_var_lib_t
/var/lib/mock(/.*)?
systemd_passwd_var_run_t
/var/run/systemd/ask-password(/.*)?
/var/run/systemd/ask-password-block(/.*)?
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
