Security-Enhanced Linux secures the abrt processes via flexible mandatory access control.
If you want to allow ABRT to run in abrt_handle_event_t domain to handle ABRT event scripts, you must turn on the abrt_handle_event boolean.
setsebool -P abrt_handle_event 1
If you want to allow users to resolve user passwd entries directly from ldap rather then 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 kerberos_enabled boolean.
setsebool -P kerberos_enabled 1
semanage fcontext -a -t public_content_t "/var/abrt(/.*)?"
restorecon -F -R -v /var/abrt
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
You can see the context of a file using the -Z option to lsP 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 transition 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.
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.
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.
abrt_tmp_t
- Set files with the abrt_tmp_t type, if you want to store abrt temporary 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.
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.
abrt_watch_log_exec_t
- Set files with the abrt_watch_log_exec_t type, if you want to transition an executable to the abrt_watch_log_t domain.
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.
You can see the context of a process using the -Z option to psP Policy governs the access confined processes have to files. SELinux abrt policy is very flexible allowing users to setup their abrt processes 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.
The SELinux user type abrt_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.
abrt_etc_t
/etc/abrt(/.*)?
abrt_tmp_t
abrt_var_cache_t
/var/cache/abrt(/.*)?
/var/spool/abrt(/.*)?
/var/cache/abrt-di(/.*)?
abrt_var_log_t
/var/log/abrt-logger
abrt_var_run_t
/var/run/abrt(/.*)?
/var/run/abrtd?.lock
/var/run/abrtd?.socket
/var/run/abrt.pid
rpm_log_t
/var/log/yum.log.*
rpm_var_cache_t
/var/cache/yum(/.*)?
/var/spool/up2date(/.*)?
/var/cache/PackageKit(/.*)?
rpm_var_run_t
/var/run/yum.*
/var/run/PackageKit(/.*)?
sysfs_t
/sys(/.*)?
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.
