Security-Enhanced Linux secures the aisexec processes via flexible mandatory access control.
If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd serve for the aisexec_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 aisexec_t, you must turn on the kerberos_enabled boolean.
setsebool -P kerberos_enabled 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 aisexec policy is very flexible allowing users to setup their aisexec processes in as secure a method as possible.
The following file types are defined for aisexec:
aisexec_exec_t
- Set files with the aisexec_exec_t type, if you want to transition an executable to the aisexec_t domain.
aisexec_initrc_exec_t
- Set files with the aisexec_initrc_exec_t type, if you want to transition an executable to the aisexec_initrc_t domain.
aisexec_tmp_t
- Set files with the aisexec_tmp_t type, if you want to store aisexec temporary files in the /tmp directories.
aisexec_tmpfs_t
- Set files with the aisexec_tmpfs_t type, if you want to store aisexec files on a tmpfs file system.
aisexec_var_lib_t
- Set files with the aisexec_var_lib_t type, if you want to store the aisexec files under the /var/lib directory.
aisexec_var_log_t
- Set files with the aisexec_var_log_t type, if you want to treat the data as aisexec var log data, usually stored under the /var/log directory.
aisexec_var_run_t
- Set files with the aisexec_var_run_t type, if you want to store the aisexec files under the /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.
You can see the context of a process using the -Z option to psP Policy governs the access confined processes have to files. SELinux aisexec policy is very flexible allowing users to setup their aisexec processes in as secure a method as possible.
The following process types are defined for aisexec:
aisexec_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 aisexec_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.
aisexec_tmp_t
aisexec_tmpfs_t
aisexec_var_lib_t
/var/lib/openais(/.*)?
aisexec_var_log_t
/var/log/cluster/aisexec.log.*
aisexec_var_run_t
/var/run/aisexec.pid
dlm_controld_tmpfs_t
fenced_tmpfs_t
gfs_controld_tmpfs_t
groupd_tmpfs_t
initrc_tmp_t
var_lib_t
/opt/(.*/)?var/lib(/.*)?
/var/lib(/.*)?
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 m
