released 25/Dec/2011 +----------------------------------------------------------------------------- + - feature: add admin "interfaces show" command to display information about + the interface cache + - feature: support GRE interface binding changes (update gre nbma address + properly, and purge peer cache) to support dual ISP setups with failover + - fix: send registration reply even when all bindings are rejected + - fix: fix really the holding-time to apply to shortcut-target + - fix: fix hop count handling + - fix: various memory leaks fixed + - fix: fix memory corruption in the hlist structure (would be visible when + opennhrp is acting as NHS with heavy traffic) + +----------------------------------------------------------------------------- + opennhrp 0.12.3 - released 19/Aug/2011 +----------------------------------------------------------------------------- + - feature: export reason why peer-down trigger was executed; and implement + 'lowerdown' opennhrpctl command for racoon hook to indicate that the + IPsec SA has died (opennhrp-script can then avoid the unneccessary and + possibly harmful call to racoonctl) + - fix: route NHRP queries always via NHS (because ipsec initial-contact + mechanism for purging dead IPsec SAs triggers after NHRP rediscovery, + and if remote peer was rebooted, the direct link might be dead) + - fix: don't negative cache entries on timeout (timeout is indication of + temporary error: none of NHS' is reachable) + - fix: don't reply to kernel's ARP queries using local route entries. + this also prevents bad shortcut-routes if the local GRE prefix is + a sub-prefix of routed subnet over the GRE + +----------------------------------------------------------------------------- + opennhrp 0.12.2 - released 07/Jul/2011 +----------------------------------------------------------------------------- + - fix: regression introduced in 0.12's policy routing changes that + shortcuts for in-NBMA network would not work unless using dynamic-map + NHS configuration (from David Ward) + +----------------------------------------------------------------------------- + opennhrp 0.12.1 - released 24/Mar/2011 +----------------------------------------------------------------------------- + - feature: export tunnel GRE key to opennhrp-script + - fix: build error against certain kernel versions and architectures + - fix: update registrations when 1/3 of the holding-time has passed as + per rfc recommendation + - fix: fix holding-time to apply properly to shortcut-target blocks + +----------------------------------------------------------------------------- + opennhrp 0.12 - released 01/Nov/2010 +----------------------------------------------------------------------------- + - feature: preliminary support for policy routing. cache kernel routes for + each gre device and use them for routing lookups. nhrp shortcut routes + should be in separate routing table. this allows nhrp message routing to + always happen using bgp/ospf routes (for shortcut refreshes) and fixes + shortcuts to converge with the main routing information. + - feature: shortcut-target config option for subnet specific holding-time + overrides and aggregation of local subnet to "summary shortcut" + - fix: delete shortcut-routes if their gateway is removed to force renewal + of the route (shortcut gateway can change due to bgp/ospf routing change) + - fix: actually remove dynamic-nhs from peers if it's A entry is removed + - fix: disallow duplicate cached entries with dynamic-nhs entries + - randomize retry timer and increase script timeouts + - improve logging a bit + +----------------------------------------------------------------------------- + opennhrp 0.11.5 - released 16/Mar/2010 +----------------------------------------------------------------------------- + - clear negative cached entries for peers which sends resolution request + - use several netlink sockets to receive notifications so we don't lose + sync on all of them + - fix shortcut renewals + - libev updated to version 3.9 + - signal handling fixed + +----------------------------------------------------------------------------- + opennhrp 0.11.4 - released 04/Mar/2010 +----------------------------------------------------------------------------- + - multicast packet relay fix + - netlink buffer sizes increased + +----------------------------------------------------------------------------- + opennhrp 0.11.3 - released 30/Oct/2009 +----------------------------------------------------------------------------- + - handle dns lookup failures properly + - fix failover for shortcut routes + - detect forwarding loops for indications + - some code cleanups + +----------------------------------------------------------------------------- + opennhrp 0.11.2 - released 25/Sep/2009 +----------------------------------------------------------------------------- + - fixed libev usage bug that could cause crash on script timeout + - make lock file closed on exec so opennhrp-script instances won't keep + opennhrp daemon lock + - fixes traffic indications to work again (captured packet length was + not right) + +----------------------------------------------------------------------------- + opennhrp 0.11.1 - released 31/Aug/2009 +----------------------------------------------------------------------------- + - update libev version to 3.8 + - more permssive build for warnings (libev generates some warnings) + - fix packet filter installation timer + - fix a false assert for peer deletion + - disable icmp redirect properly + - minor fixes to documentation and example script + +----------------------------------------------------------------------------- + opennhrp 0.11 - released 18/Jun/2009 +----------------------------------------------------------------------------- + - introduce 'dynamic-map' directive to autodetect all next hop servers + from a domain name with multiple A entries + - 'multicast' directive to better control softswitching of multicast + packets + - use libev instead of the self written event handling code + - enable Forward NHS extension for Traffic Indications to drop the message + after it has visited all NHS:es (otherwise it would loop between them + until ttl expires) + - performance optimizations to packet capturing, multicast packet process + switching, handling of registration requests and logging + - fix 64-bit compatibility issues + - some code documentation and clean ups + +----------------------------------------------------------------------------- + opennhrp 0.10.3 - released 04/May/2009 +----------------------------------------------------------------------------- + -
