Definitions ¶

event-type ¶

type:

enum

enum-name:

mptcp-event-type

name-prefix:

mptcp-event-

entries:

unspec:: unused event
created:: token, family, saddr4 | saddr6, daddr4 | daddr6, sport, dport A new MPTCP connection has been created. It is the good time to allocate memory and send ADD_ADDR if needed. Depending on the traffic-patterns it can take a long time until the MPTCP_EVENT_ESTABLISHED is sent.
established:: token, family, saddr4 | saddr6, daddr4 | daddr6, sport, dport A MPTCP connection is established (can start new subflows).
closed:: token A MPTCP connection has stopped.
announced:: token, rem_id, family, daddr4 | daddr6 [, dport] A new address has been announced by the peer.
removed:: token, rem_id An address has been lost by the peer.
sub-established:: token, family, loc_id, rem_id, saddr4 | saddr6, daddr4 | daddr6, sport, dport, backup, if_idx [, error] A new subflow has been established. ‘error’ should not be set.
sub-closed:: token, family, loc_id, rem_id, saddr4 | saddr6, daddr4 | daddr6, sport, dport, backup, if_idx [, error] A subflow has been closed. An error (copy of sk_err) could be set if an error has been detected for this subflow.
sub-priority:: token, family, loc_id, rem_id, saddr4 | saddr6, daddr4 | daddr6, sport, dport, backup, if_idx [, error] The priority of a subflow has changed. ‘error’ should not be set.
listener-created:: family, sport, saddr4 | saddr6 A new PM listener is created.
listener-closed:: family, sport, saddr4 | saddr6 A PM listener is closed.
