In the 3.x linux kernel, the sctp states are defined differently between kernel and uapi. Is that a mismatch or am I missing something?
in include/uapi/linux/sctp.h
/* Association states. */
enum sctp_sstat_state {
SCTP_EMPTY = 0,
SCTP_CLOSED = 1,
SCTP_COOKIE_WAIT = 2,
SCTP_COOKIE_ECHOED = 3,
SCTP_ESTABLISHED = 4,
SCTP_SHUTDOWN_PENDING = 5,
SCTP_SHUTDOWN_SENT = 6,
SCTP_SHUTDOWN_RECEIVED = 7,
SCTP_SHUTDOWN_ACK_SENT = 8,
};
in include/net/sctp/constants.h
/* SCTP state defines for internal state machine */
typedef enum {
SCTP_STATE_CLOSED = 0,
SCTP_STATE_COOKIE_WAIT = 1,
SCTP_STATE_COOKIE_ECHOED = 2,
SCTP_STATE_ESTABLISHED = 3,
SCTP_STATE_SHUTDOWN_PENDING = 4,
SCTP_STATE_SHUTDOWN_SENT = 5,
SCTP_STATE_SHUTDOWN_RECEIVED = 6,
SCTP_STATE_SHUTDOWN_ACK_SENT = 7,
} sctp_state_t;
and it looks like the SCTP_STATE_EMPTY was removed by this patch: http://lists.openwall.net/netdev/2011/04/20/31
