Subject: sctp: Fix the SNMP number of SCTP_MIB_CURRESTAB
X-Git-Tag: v2.6.28-rc1~717^2~20
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3d5a019d5761a40465337711ae7d2beb1e9b43ec;p=pandora-kernel.git

sctp: Fix the SNMP number of SCTP_MIB_CURRESTAB

RFC3873 defined SCTP_MIB_CURRESTAB:
  sctpCurrEstab OBJECT-TYPE
    SYNTAX         Gauge32
    MAX-ACCESS     read-only
    STATUS         current
    DESCRIPTION
         "The number of associations for which the current state is
         either ESTABLISHED, SHUTDOWN-RECEIVED or SHUTDOWN-PENDING."
    REFERENCE
         "Section 4 in RFC2960 covers the SCTP   Association state
         diagram."

If the T4 RTO timer expires many times(timeout), the association will enter
CLOSED state, so we should dec the number of SCTP_MIB_CURRESTAB, not inc the
number of SCTP_MIB_CURRESTAB.
