Security Enhanced Linux Policy for the mock processes
Security-Enhanced Linux secures the mock processes via flexible mandatory access control.
The mock processes execute with the mock_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.
ps -eZ | grep mock_t
The mock_t SELinux type can be entered via the mock_exec_t file type.
The default entrypoint paths for the mock_t domain are the following:
SELinux defines process types (domains) for each process running on the system
You can see the context of a process using the -Z option to psbP
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:
Note: semanage permissive -a mock_t can be used to make the process type mock_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.
SELinux policy is customizable based on least access required. mock policy is extremely flexible and has several booleans that allow you to manipulate the policy and run mock with the tightest access possible.
If you want to allow mock to read files in home directories, you must turn on the mock_enable_homedirs boolean. Disabled by default.
setsebool -P mock_enable_homedirs 1
If you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.
setsebool -P nis_enabled 1
If you want to support NFS home directories, you must turn on the use_nfs_home_dirs boolean. Disabled by default.
setsebool -P use_nfs_home_dirs 1
If you want to support SAMBA home directories, you must turn on the use_samba_home_dirs boolean. Disabled by default.
setsebool -P use_samba_home_dirs 1
The SELinux process 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.
SELinux requires files to have an extended attribute to define the file type.
You can see the context of a file using the -Z option to lsbP
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.
STANDARD FILE CONTEXT
SELinux defines the file context types for the mock, if you wanted to store files with these types in a different paths, you need to execute the semanage command to specify alternate labeling and then use restorecon to put the labels on disk.
semanage fcontext -a -t mock_exec_t '/srv/mock/content(/.*)?'
restorecon -R -v /srv/mymock_content
Note: SELinux often uses regular expressions to specify labels that match multiple files.
The following file types are defined for mock:
- Set files with the mock_build_exec_t type, if you want to transition an executable to the mock_build_t domain.
- Set files with the mock_cache_t type, if you want to store the files under the /var/cache directory.
- Set files with the mock_etc_t type, if you want to store mock files in the /etc directories.
- Set files with the mock_exec_t type, if you want to transition an executable to the mock_t domain.
- Set files with the mock_tmp_t type, if you want to store mock temporary files in the /tmp directories.
- Set files with the mock_var_lib_t type, if you want to store the mock files under the /var/lib directory.
- Set files with the mock_var_run_t type, if you want to store the mock 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 fcontext can also be used to manipulate default file context mappings.
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.
