| H A D | ifnet.9 | diff 142501 Fri Feb 25 17:46:41 MST 2005 brooks Change the definition of struct if_data's member ifi_epoch from wall clock time to uptime because wall clock time may go backwards. This is a change in the API which will impact SNMP agents who are using ifi_epoch to set RFC2233's ifCounterDiscontinuityTime. None are know to exist today. This will not impact applications that are using the <index, epoch> tuple to verify interface uniqueness except that it eliminates a race which could lead to a false assumption of uniqueness. Because this is a behavior change, bump __FreeBSD_version. Discussed with: re (jhb, scottl) MFC after: 3 days Pointed out by: pkh (way back at EuroBSDCon) Pointy hat: brooks |
