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.

ipcpd: Shut down DHT gracefully during enrollment

2018-05-03T08:27:39+00:00

The DHT has a thread that continued to run during shutdown. The shutdown state is now checked for. It will not try to send messages at shutdown. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Create notifier before connmgr

2018-04-26T10:57:59+00:00

The connmgr requires the notifier, but the notifier was created after and destroyed before the connmgr. This is now fixed. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Enable locking threads to a CPU core

2018-04-05T08:31:52+00:00

This adds a function that locks a thread to a random core. This greatly improves performance on multi-cpu systems. There is no portable way to do this, this only implements it for GNU/Linux. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders
