ipcpd: Fix check build for DHT

2018-05-08T12:52:04+00:00

The DHT test failed on the use of IPCP-specific calls. These calls are now guarded by the correct defition checks. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Include ipcp-dev header in DHT

2018-05-08T10:07:01+00:00

The DHT called ipcp_sdb_release without including ipcp-dev, causing compiler errors on some machines. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Fix bad memory handling in LFA policy

2018-05-04T10:11:17+00:00

The Loop-Free Alternates policy had bad memory management in two places. In the calculation of the LFAs a table was freed in the first iteration of a loop, whereas it was still needed in the other iterations. It is now freed outside of the loop. In the alternate PFF the address structs were not freed upon shutdown, this has been added as well. It also fixes some bad initialization in the LFA calculation function.

ipcpd: Limit number of returned query addresses

2018-05-03T18:33:50+00:00

The query returned all addresses where a name was registered, causing some scaling problems. Now it will return at most DHT_RETR_ADDR, which is currently set at 1 (anycast). Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Allow wait for dir enrollment on dt conn

2018-05-03T15:56:11+00:00

This adds the option to wait for the directory (DHT) to enroll on creating a new data transfer connection. This makes scripting network bootstraps more stable. The default setting is OFF. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Recalculate PFF upon adding new neighbor

2018-05-03T15:53:09+00:00

This recalculates the PFF upon adding a new neighbor, so that the network reconverges faster. It is safe to do so since it is only done by the two IPCPs that established the new flow. The PFF is also recalculated every 4 seconds. Signed-off-by: Sander Vrijders Signed-off-by: Dimitri Staessens

ipcpd: Prevent parallel DHT enrollment threads

2018-05-03T12:35:08+00:00

This will prevent quick calls to ipcp conn for dt flows to create multiple join threads in parallel, instead the subsequent calls will wait for the pending join to finish. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Don't do lookup with new DT when running

2018-05-03T09:00:58+00:00

The DHT performed a lookup upon a new DT connection when it was running for efficiency reasons. This lookup somehow cause SEGV under stress (rapid bootstrapping of networks). This will be solved with a full revision of the DHT implementation. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Cleanup pending DHT commands on shutdown

2018-05-03T08:27:47+00:00

The list of commands was not cleaned up on shutdown. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Remove cookie from DHT lookup at update

2018-05-03T08:27:43+00:00

The lookup struct uses the cookies to track pending request messages, but they were not removed when a response is processed. Upon reuse of a cookie for the next message, it could update the wrong lookup. This removes the cookie for a lookup when it is looked for.
