SCTP INIT checksum stops working after upgrading to RHEL 6.5

Solution Verified - Updated -

Issue

  • After upgrading to RHEL 6.5 SCTP stops working on bonded interfaces.
  • SCTP is initiating INIT messages without checksum.
  • NIC bonding is done on system and application is initiating SCTP INIT messages. In wireshark traces it is displaying as "Checksum: 0x00000000 (not verified)". because checksum is going as 0x00000000 in INIT message the SCTP links are not coming up. We need to enable CRC32 in SCTP init messages

Environment

    • kernel-2.6.32-431.el6
    • kernel-2.6.32-431.1.2.el6
