* | isisd: fix wrong next-hops from SPFPeter Szilagyi2012-02-143-29/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The forwarding table was filled with wrong next-hops, and which is even worse, it was done in a totally non-deterministic way. The next-hop set for an IP prefix by isisd was the neighbor IS from which the flooded LSP about the IP prefix was arrived. So, if an IS received all the LSPs through its, say, eth0 interface, all entries in the forwarding table contained the next IS reachable via eth0 as the next-hop. The solution is to propagate the correct next-hop further from node to node as the SPF algorithm traverses the graph and selects the next node to be added to the set of already covered nodes. Also, the construction of the tentative node list (the nodes where the shortest path is not known yet) was buggy: if a node was already a member of this list with a certain path cost, and an alternative path was found to it with a lower cost while processing a pseudo-node LSP, it was not added to the list. This way, the path selected by isisd for a certain prefix was the first one it encountered during the LSDB processing. Signed-off-by: Fritz Reichmann <fritz@reichmann.nl>
* | isisd: send proper LSP after DIS electionPeter Szilagyi2012-02-141-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | After an IS has been elected as the Designated IS for a LAN, it did not refresh the content of the pseudo-node after a new node has been connected to the same LAN. Instead, the periodically reoriginated pseudo-node LSP still contained only those IS neighbors that were already present when the DIS election process was commenced. The fix for the problem schedules an LSP regeneration rather than just reoriginating the same LSP with the old content. Signed-off-by: Fritz Reichmann <fritz@reichmann.nl>
* | isisd: fix circuit state machinePeter Szilagyi2012-02-145-64/+79
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | isisd has a so-called circuit state machine that takes care about the interface state changes, such as initializing, down, up. When an interface was brought down by a link failure, the interface information was deleted and set to NULL. When the link was restored later, the interface was looked up by the old pointer, but since it was cleared, it was never found again, resulting in an interface never entering the up state again. Also, the program regularly crashed because of a deleted pointer in the same context which was later accessed without any further checking. Signed-off-by: Fritz Reichmann <fritz@reichmann.nl>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There was a regression introduced with the previous commit: "ipv6 nd home-agent-lifetime 1800000" appeared by default in every interface section of running-config, although this command is invalid in this context.

Reason: the ifindex check is on the same level as the check for ZEBRA_ROUTE_CONNECT/NEXTHOP_TYPE_IFINDEX. If everything matches except for the ifindex, the "else" part (intended for different route types) is executed, thus removing the route from the wrong interface. fix: move ifindex check inside the "then" part of the check for ZEBRA_ROUTE_CONNECT/NEXTHOP_TYPE_IFINDEX. Now connected routes to other ifindexes will not spill over to the "else" part for different route types anymore.

| | | | | | | | | | | | | | | | | | | | | | | | ZEBRA_HELLO message is used by routing daemons to inform zebra what type of routes daemon will be announcing to zebra. Also zebra uses route_type_oaths array to track which daemon announces which protocol. Zebra mops up routes if daemon didn't for some reason.
