NAME

       cgrulesengd - control group rules daemon

SYNOPSIS

       cgrulesengd [options]

DESCRIPTION

       cgrulesengd  is	a  daemon,  which  distributes processes to control groups. When any process changes its effective UID or GID, cgrulesengd
       inspects the list of rules loaded from the cgrules.conf file and moves the process to the appropriate control group.

       The list of rules is read during the daemon startup is are cached in the daemon's memory.  The daemon reloads the list  of  rules  when	it
       receives SIGUSR2 signal.  The daemon reloads the list of templates when it receives SIGUSR1 signal.

       The daemon opens a standard unix socket to receive 'sticky' requests from cgexec.

OPTIONS

       -h|--help
	      Display help.

       -f <path>|--logfile=<path>
	      Write  log  messages to the given log file. When '-' is used as <path>, log messages are written to the standard output. If '-f' and
	      '-s' are used together, the logs are sent to both destinations.

       -s[facility]|--syslog=[facility]
	      Write log messages to syslog. The default facility is DAEMON. If '-f' and '-s' are used together, the logs are sent to both destina-
	      tions.

       -n|--nodaemon
	      Don't fork the daemon, stay in the foreground.

       -v|--verbose
	      Display more log messages. This option can be used three times to enable more verbose log messages.

       -q|--quiet
	      Display less log messages.

       -Q|--nolog
	      Disable logging.

       -d|--debug
	      Equivalent to '-nvvvf -', i.e. don't fork the daemon, display all log messages and write them to the standard output.

       -u <user>|--socket-user=<user>
	      -g  <group>|--socket-group=<group>  Set the owner of cgrulesengd socket. Assumes that cgexec runs with proper suid permissions so it
	      can write to the socket when cgexec --sticky is used.

ENVIRONMENT VARIABLES

       CGROUP_LOGLEVEL
	      controls verbosity of the tool. Allowed values are DEBUG, INFO, WARNING or ERROR.

FILES

       /etc/cgrules.conf

NAME

       cgdcbxd - control group dcb event net_prio daemon

SYNOPSIS

       cgdcbxd [options]

DESCRIPTION

       cgdcbxd	is a daemon used to monitor DCB netlink events and manage the net_prio control group subsystem. The daemon keeps the hierarchy and
       priority mappings in sync with DCBX Application events.

       When a DCB netlink event is received cgdcbxd parses the application TLV and identifies new, updated, and deleted  application  tuples.  The
       DCBX application TLV uses the selector, protocol ID and priority fields to identify and set application priority. The selector field speci-
       fies the protocol ID type supported types are

       Ethertype = 1
       TCP or SCTP = 2
       UDP or DCCP = 3
       TCP, SCTP UDP, and DCCP = 4

       The protocol ID field specifies the port or ethertype depending on the selector field and the priority gives a priority value  (0-7).  Used
       to set the net_prio.ifpriomap.

       When  a new application tuple is identified cgdcbxd creates a control group under the net_prio subsystem using the directory cgdcbx-<selec-
       tor>-<protocolID>.

       The <selector> field uses the IEEE selector values listed above for both CEE DCBX and IEEE DCBX versions.

       This control group will be managed by cgdcbx and the ifpriomap will be kept in sync with the  application  TLV.	If  a  DCB  netlink  event
       removes the application selector-protocolID tuple then cgdcbx removes the control group.

       This  may  be  used with cgrulesengd to create configuration rules that map applications and users to DCBX selector-protocolID tuples. Note
       protocol ID and selector values use the well-known protocol type and port or ethertype defined  by  the	IANA  (Internet  Assigned  Numbers
       Authority) the application are not required to use the well-known ports this is only used to identify the application.

OPTIONS

       -h     Display help.

       -n     Don't fork the daemon, stay in the foreground.

       -v     Show version

FILES

       /etc/cgrules.conf
       the default libcgroup configuration file

NOTES

       Support for the net_prio subsystem was added in the 3.3 Linux kernel.

Signals
       SIGUSR1 dumps list of managed interfaces and control groups with priomaps.
