NAMEipa_helper_selinux − Security Enhanced Linux Policy for the ipa_helper processes
DESCRIPTIONSecurity-Enhanced Linux secures the ipa_helper processes via flexible mandatory access control. The ipa_helper processes execute with the ipa_helper_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 ipa_helper_t
ENTRYPOINTSThe ipa_helper_t SELinux type can be entered via the ipa_helper_exec_t file type. The default entrypoint paths for the ipa_helper_t domain are the following: /usr/libexec/ipa/com.redhat.idm.trust-fetch-domains, /usr/libexec/ipa/oddjob/org.freeipa.server.conncheck, /usr/libexec/ipa/oddjob/com.redhat.idm.trust-fetch-domains
PROCESS TYPESSELinux 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 ipa_helper policy is very flexible allowing users to setup their ipa_helper processes in as secure a method as possible. The following process types are defined for ipa_helper: ipa_helper_tNote: semanage permissive -a ipa_helper_t can be used to make the process type ipa_helper_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.
BOOLEANSSELinux policy is customizable based on least access required. ipa_helper policy is extremely flexible and has several booleans that allow you to manipulate the policy and run ipa_helper with the tightest access possible. 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 httpd processes to run IPA helper, you must turn on the httpd_run_ipa boolean. Disabled by default. setsebool -P httpd_run_ipa 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
MANAGED FILESThe SELinux process type ipa_helper_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.
ipa_log_t /var/log/ipa(/.*)?
/var/log/ipareplica-conncheck.log.*
ipa_var_run_t /var/run/ipa(/.*)?
FILE CONTEXTSSELinux 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 ipa_helper policy is very flexible allowing users to setup their ipa_helper processes in as secure a method as possible. The following file types are defined for ipa_helper: ipa_helper_exec_t- Set files with the ipa_helper_exec_t type, if you want to transition an executable to the ipa_helper_t domain.
Paths: /usr/libexec/ipa/com.redhat.idm.trust-fetch-domains, /usr/libexec/ipa/oddjob/org.freeipa.server.conncheck, /usr/libexec/ipa/oddjob/com.redhat.idm.trust-fetch-domains 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.
COMMANDSsemanage 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.
