DESCRIPTION
Security-Enhanced Linux secures the abrt processes via flexible manda‐
tory 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
NSSWITCH DOMAIN
If you want to allow users to login using a sssd serve for the
abrt_helper_t, abrt_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
abrt_helper_t, abrt_t, you must turn on the allow_kerberos boolean.
setsebool -P allow_kerberos 1
If you want to allow system to run with NI for the abrt_helper_t,
abrt_t, you must turn on the allow_ypbind boolean.
setsebool -P allow_ypbind 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_abrtd_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.
Paths:
/usr/sbin/abrtd, /usr/sbin/abrt-dbus
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_unit_file_t
- Set files with the abrt_unit_file_t type, if you want to treat the
files as abrt unit content.
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/spool/abrt(/.*)?, /var/cache/abrt-
di(/.*)?
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
abrt_watch_log_exec_t
- Set files with the abrt_watch_log_exec_t type, if you want to transi‐
tion an executable to the abrt_watch_log_t domain.
Note: File context can be temporarily modified with the chcon command.
If you want to permanantly change the file context you need to use the
semanage fcontext command. This will modify the SELinux labeling data‐
base. 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, abrt_watch_log_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.
