RASDAEMON(8) RAS memory controller admin utility RASDAEMON(8)NAME
rasdaemon - RAS daemon to log the RAS events.
SYNOPSIS
rasdaemon [OPTION]...
DESCRIPTION
The rasdaemon program is a daemon with monitors the RAS trace events from /sys/kernel/debug/tracing, reporting them via syslog/journald.
OPTIONS --usage
Display a brief usage message and exit.
--help Display a help message and exit.
--disable
Disable RAS tracing events and exit.
--enable
Enable RAS tracing events and exit.
--foreground
Executes in foreground, printing the events at console. Useful for testing it, and to be used by systemd or Unix System V respan.
If not specified, the program runs in daemon mode.
--version
Prints the program version and exit.

rasdaemon_selinux - Security Enhanced Linux Policy for the rasdaemon processes
DESCRIPTION
Security-Enhanced Linux secures the rasdaemon processes via flexible mandatory access control.
The rasdaemon processes execute with the rasdaemon_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 rasdaemon_t
ENTRYPOINTS
The rasdaemon_t SELinux type can be entered via the rasdaemon_exec_t file type.
The default entrypoint paths for the rasdaemon_t domain are the following:
/usr/sbin/rasdaemon, /usr/sbin/ras-mc-ctl
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 rasdaemon policy is very flexible allowing users to setup their ras-
daemon processes in as secure a method as possible.
The following process types are defined for rasdaemon:
rasdaemon_t
Note: semanage permissive -a rasdaemon_t can be used to make the process type rasdaemon_t permissive. SELinux does not deny access to per-
missive process types, but the AVC (SELinux denials) messages are still generated.
BOOLEANS
SELinux policy is customizable based on least access required. rasdaemon policy is extremely flexible and has several booleans that allow
you to manipulate the policy and run rasdaemon with the tightest access possible.
If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd server, you must turn on the authlo-
gin_nsswitch_use_ldap boolean. Disabled by default.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow all daemons to write corefiles to /, you must turn on the daemons_dump_core boolean. Disabled by default.
setsebool -P daemons_dump_core 1
If you want to enable cluster mode for daemons, you must turn on the daemons_enable_cluster_mode boolean. Enabled by default.
setsebool -P daemons_enable_cluster_mode 1
If you want to allow all daemons to use tcp wrappers, you must turn on the daemons_use_tcp_wrapper boolean. Disabled by default.
setsebool -P daemons_use_tcp_wrapper 1
If you want to allow all daemons the ability to read/write terminals, you must turn on the daemons_use_tty boolean. Disabled by default.
setsebool -P daemons_use_tty 1
If you want to deny any process from ptracing or debugging any other processes, you must turn on the deny_ptrace boolean. Enabled by
default.
setsebool -P deny_ptrace 1
If you want to allow all domains to use other domains file descriptors, you must turn on the domain_fd_use boolean. Enabled by default.
setsebool -P domain_fd_use 1
If you want to allow all domains to have the kernel load modules, you must turn on the domain_kernel_load_modules boolean. Disabled by
default.
setsebool -P domain_kernel_load_modules 1
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 enable reading of urandom for all domains, you must turn on the global_ssp boolean. Disabled by default.
setsebool -P global_ssp 1
If you want to allow confined applications to run with kerberos, you must turn on the kerberos_enabled boolean. Enabled by default.
setsebool -P kerberos_enabled 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
If you want to allow confined applications to use nscd shared memory, you must turn on the nscd_use_shm boolean. Enabled by default.
setsebool -P nscd_use_shm 1
NSSWITCH DOMAIN
If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd server for the rasdaemon_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 rasdaemon_t, you must turn on the kerberos_enabled boolean.
setsebool -P kerberos_enabled 1
MANAGED FILES
The SELinux process type rasdaemon_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.
cluster_conf_t
/etc/cluster(/.*)?
cluster_var_lib_t
/var/lib/pcsd(/.*)?
/var/lib/cluster(/.*)?
/var/lib/openais(/.*)?
/var/lib/pengine(/.*)?
/var/lib/corosync(/.*)?
/usr/lib/heartbeat(/.*)?
/var/lib/heartbeat(/.*)?
/var/lib/pacemaker(/.*)?
cluster_var_run_t
/var/run/crm(/.*)?
/var/run/cman_.*
/var/run/rsctmp(/.*)?
/var/run/aisexec.*
/var/run/heartbeat(/.*)?
/var/run/cpglockd.pid
/var/run/corosync.pid
/var/run/rgmanager.pid
/var/run/cluster/rgmanager.sk
debugfs_t
rasdaemon_var_lib_t
/var/lib/rasdaemon(/.*)?
root_t
/
/initrd
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 rasdaemon policy is very flexible allowing users to setup their
rasdaemon processes in as secure a method as possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the rasdaemon, if you wanted to store files with these types in a diffent paths, you need to
execute the semanage command to sepecify alternate labeling and then use restorecon to put the labels on disk.
semanage fcontext -a -t rasdaemon_exec_t '/srv/rasdaemon/content(/.*)?'
restorecon -R -v /srv/myrasdaemon_content
Note: SELinux often uses regular expressions to specify labels that match multiple files.
The following file types are defined for rasdaemon:
rasdaemon_exec_t
- Set files with the rasdaemon_exec_t type, if you want to transition an executable to the rasdaemon_t domain.
Paths:
/usr/sbin/rasdaemon, /usr/sbin/ras-mc-ctl
rasdaemon_unit_file_t
- Set files with the rasdaemon_unit_file_t type, if you want to treat the files as rasdaemon unit content.
Paths:
/usr/lib/systemd/system/rasdaemon.*, /usr/lib/systemd/system/ras-mc-ctl.*
rasdaemon_var_lib_t
- Set files with the rasdaemon_var_lib_t type, if you want to store the rasdaemon files under the /var/lib 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.
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 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.
