NAME abrt_selinux - Security Enhanced Linux Policy for the abrt processes

DESCRIPTION SELinux Linux secures abrt (ABRT - automated bug-reporting tool) pro- cesses via flexible mandatory access control.

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

If you want to allow ABRT to run in abrt_handle_event_t domain to han- dle ABRT event script, you must turn on the abrt_handle_event boolean.

setsebool -P abrt_handle_event 1

SHARING FILES If you want to share files with multiple domains (Apache, FTP, rsync, Samba), you can set a file context of public_content_t and public_con- tent_rw_t. These context allow any of the above domains to read the content. If you want a particular domain to write to the public_con- tent_rw_t domain, you must set the appropriate boolean.

Allow abrt servers to read the /var/abrt directory by adding the pub- lic_content_t file type to the directory and by restoring the file type.

semanage fcontext -a -t public_content_t "/var/abrt(/.*)?" restorecon -F -R -v /var/abrt

Allow abrt servers to read and write /var/tmp/incoming by adding the public_content_rw_t type to the directory and by restoring the file type. This also requires the allow_abrt_anon_write boolean to be set.

semanage fcontext -a -t public_content_rw_t "/var/abrt/incoming(/.*)?" restorecon -F -R -v /var/abrt/incoming

If you want to allow ABRT to modify public files used for public file transfer services., you must turn on the abrt_anon_write boolean.

setsebool -P abrt_anon_write 1

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

The following file types are defined for abrt:

abrt_dump_oops_exec_t

- Set files with the abrt_dump_oops_exec_t type, if you want to transi- tion an executable to the abrt_dump_oops_t domain.

abrt_etc_t

- Set files with the abrt_etc_t type, if you want to store abrt files in the /etc directories.

abrt_exec_t

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

abrt_handle_event_exec_t

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

abrt_helper_exec_t

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

abrt_initrc_exec_t

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

abrt_retrace_cache_t

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

Paths: /var/cache/retrace-server(/.*)?, /var/cache/abrt-retrace(/.*)?

abrt_retrace_coredump_exec_t

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

abrt_retrace_spool_t

- Set files with the abrt_retrace_spool_t type, if you want to store the abrt retrace files under the /var/spool directory.

Paths: /var/spool/retrace-server(/.*)?, /var/spool/abrt-retrace(/.*)?

abrt_retrace_worker_exec_t

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

Paths: /usr/bin/retrace-server-worker, /usr/bin/abrt-retrace-worker

abrt_tmp_t

- Set files with the abrt_tmp_t type, if you want to store abrt tempo- rary files in the /tmp directories.

abrt_var_cache_t

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

Paths: /var/cache/abrt(/.*)?, /var/cache/abrt-di(/.*)?, /var/spool/abrt(/.*)?

abrt_var_log_t

- Set files with the abrt_var_log_t type, if you want to treat the data as abrt var log data, usually stored under the /var/log directory.

abrt_var_run_t

- Set files with the abrt_var_run_t type, if you want to store the abrt files under the /run directory.

Paths: /var/run/abrtd?.socket, /var/run/abrtd?.lock, /var/run/abrt(/.*)?, /var/run/abrt.pid

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.

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 abrt policy is very flexible allowing users to setup their abrt pro- cesses in as secure a method as possible.

The following process types are defined for abrt:

abrt_handle_event_t, abrt_helper_t, abrt_retrace_coredump_t, abrt_t, abrt_retrace_worker_t, abrt_dump_oops_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.

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 pol- icy modules.

semanage boolean can also be used to manipulate the booleans

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