NAME¶

swift_selinux - Security Enhanced Linux Policy for the swift processes

DESCRIPTION¶

Security-Enhanced Linux secures the swift processes via flexible mandatory access control.

The swift processes execute with the swift_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 swift_t

ENTRYPOINTS¶

The swift_t SELinux type can be entered via the swift_exec_t file type.

The default entrypoint paths for the swift_t domain are the following:

/usr/bin/swift-object-info, /usr/bin/swift-proxy-server, /usr/bin/swift-object-server, /usr/bin/swift-account-reaper, /usr/bin/swift-account-server, /usr/bin/swift-container-sync, /usr/bin/swift-object-auditor, /usr/bin/swift-object-expirer, /usr/bin/swift-object-updater, /usr/bin/swift-account-auditor, /usr/bin/swift-container-server, /usr/bin/swift-container-auditor, /usr/bin/swift-container-updater, /usr/bin/swift-object-replicator, /usr/bin/swift-account-replicator, /usr/bin/swift-container-reconciler, /usr/bin/swift-container-replicator

PROCESS TYPES¶

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 ps

Policy governs the access confined processes have to files. SELinux swift policy is very flexible allowing users to setup their swift processes in as secure a method as possible.

The following process types are defined for swift:

swift_t

Note: semanage permissive -a swift_t can be used to make the process type swift_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.

BOOLEANS¶

SELinux policy is customizable based on least access required. swift policy is extremely flexible and has several booleans that allow you to manipulate the policy and run swift with the tightest access possible.

If you want to determine whether swift can connect to all TCP ports, you must turn on the swift_can_network boolean. Disabled by default.

setsebool -P swift_can_network 1

If you want to dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on the daemons_dontaudit_scheduling boolean. Enabled by default.

setsebool -P daemons_dontaudit_scheduling 1

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

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

PORT TYPES¶

SELinux defines port types to represent TCP and UDP ports.

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 swift policy is very flexible allowing users to setup their swift processes in as secure a method as possible.

The following port types are defined for swift:

swift_port_t

Default Defined Ports: tcp 6200-6203

MANAGED FILES¶

FILE CONTEXTS¶

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 ls

Policy governs the access confined processes have to these files. SELinux swift policy is very flexible allowing users to setup their swift processes in as secure a method as possible.

STANDARD FILE CONTEXT

SELinux defines the file context types for the swift, 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 swift_data_t '/srv/myswift_content(/.*)?'
restorecon -R -v /srv/myswift_content

Note: SELinux often uses regular expressions to specify labels that match multiple files.

The following file types are defined for swift:

swift_data_t

- Set files with the swift_data_t type, if you want to treat the files as swift content.

Paths:

/srv/node(/.*)?, /var/lib/swift(/.*)?, /srv/loopback-device(/.*)?

swift_exec_t

- Set files with the swift_exec_t type, if you want to transition an executable to the swift_t domain.

Paths:

/usr/bin/swift-object-info, /usr/bin/swift-proxy-server, /usr/bin/swift-object-server, /usr/bin/swift-account-reaper, /usr/bin/swift-account-server, /usr/bin/swift-container-sync, /usr/bin/swift-object-auditor, /usr/bin/swift-object-expirer, /usr/bin/swift-object-updater, /usr/bin/swift-account-auditor, /usr/bin/swift-container-server, /usr/bin/swift-container-auditor, /usr/bin/swift-container-updater, /usr/bin/swift-object-replicator, /usr/bin/swift-account-replicator, /usr/bin/swift-container-reconciler, /usr/bin/swift-container-replicator

swift_lock_t

- Set files with the swift_lock_t type, if you want to treat the files as swift lock data, stored under the /var/lock directory

swift_tmp_t

- Set files with the swift_tmp_t type, if you want to store swift temporary files in the /tmp directories.

swift_tmpfs_t

- Set files with the swift_tmpfs_t type, if you want to store swift files on a tmpfs file system.

swift_unit_file_t

- Set files with the swift_unit_file_t type, if you want to treat the files as swift unit content.

swift_var_cache_t

- Set files with the swift_var_cache_t type, if you want to store the files under the /var/cache directory.

swift_var_run_t

- Set files with the swift_var_run_t type, if you want to store the swift 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.

COMMANDS¶

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 port can also be used to manipulate the port definitions

semanage boolean can also be used to manipulate the booleans

system-config-selinux is a GUI tool available to customize SELinux policy settings.
