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-object-server, /usr/bin/swift-account-reaper, /usr/bin/swift-account-server, /usr/bin/swift-con-
       tainer-sync, /usr/bin/swift-object-auditor, /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-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 pro-
       cesses 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 allow users to resolve user passwd entries directly from ldap rather then using a sssd server, you must turn on the  authlo-
       gin_nsswitch_use_ldap boolean. Disabled by default.

       setsebool -P authlogin_nsswitch_use_ldap 1

       If you want to allow all daemons to write corefiles to /, you must turn on the daemons_dump_core boolean. Disabled by default.

       setsebool -P daemons_dump_core 1

       If you want to enable cluster mode for daemons, you must turn on the daemons_enable_cluster_mode boolean. Enabled by default.

       setsebool -P daemons_enable_cluster_mode 1

       If you want to allow all daemons to use tcp wrappers, you must turn on the daemons_use_tcp_wrapper boolean. Disabled by default.

       setsebool -P daemons_use_tcp_wrapper 1

       If you want to allow all daemons the ability to read/write terminals, you must turn on the daemons_use_tty boolean. Disabled by default.

       setsebool -P daemons_use_tty 1

       If  you	want  to  deny	any  process  from ptracing or debugging any other processes, you must turn on the deny_ptrace boolean. Enabled by
       default.

       setsebool -P deny_ptrace 1

       If you want to allow all domains to use other domains file descriptors, you must turn on the domain_fd_use boolean. Enabled by default.

       setsebool -P domain_fd_use 1

       If you want to allow all domains to have the kernel load modules, you must turn on  the	domain_kernel_load_modules  boolean.  Disabled	by
       default.

       setsebool -P domain_kernel_load_modules 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 enable reading of urandom for all domains, you must turn on the global_ssp boolean. Disabled by default.

       setsebool -P global_ssp 1

       If you want to allow confined applications to run with kerberos, you must turn on the kerberos_enabled boolean. Enabled by default.

       setsebool -P kerberos_enabled 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 allow confined applications to use nscd shared memory, you must turn on the nscd_use_shm boolean. Disabled by default.

       setsebool -P nscd_use_shm 1

NSSWITCH DOMAIN

       If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd server for the swift_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 swift_t, you must turn on the kerberos_enabled boolean.

       setsebool -P kerberos_enabled 1

MANAGED FILES

       The SELinux process type swift_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.

       cluster_conf_t

	    /etc/cluster(/.*)?

       cluster_var_lib_t

	    /var/lib/pcsd(/.*)?
	    /var/lib/cluster(/.*)?
	    /var/lib/openais(/.*)?
	    /var/lib/pengine(/.*)?
	    /var/lib/corosync(/.*)?
	    /usr/lib/heartbeat(/.*)?
	    /var/lib/heartbeat(/.*)?
	    /var/lib/pacemaker(/.*)?

       cluster_var_run_t

	    /var/run/crm(/.*)?
	    /var/run/cman_.*
	    /var/run/rsctmp(/.*)?
	    /var/run/aisexec.*
	    /var/run/heartbeat(/.*)?
	    /var/run/cpglockd.pid
	    /var/run/corosync.pid
	    /var/run/rgmanager.pid
	    /var/run/cluster/rgmanager.sk

       root_t

	    /
	    /initrd

       swift_data_t

	    /srv/node(/.*)?
	    /srv/loopback-device(/.*)?

       swift_tmp_t

       swift_var_cache_t

	    /var/cache/swift(/.*)?

       swift_var_run_t

	    /var/run/swift(/.*)?

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 diffent paths, you need to execute
       the semanage command to sepecify alternate labeling and then use restorecon to put the labels on disk.

       semanage fcontext -a -t swift_data_t '/srv/swift/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(/.*)?, /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-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-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-replicator

       swift_tmp_t

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

       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 boolean can also be used to manipulate the booleans

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