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

lib: Allow disabling partial read

2018-03-19T09:29:21+00:00

This allows disabling partial reads. It adds a flag FLOWFRNOPART that disables partial reads. Partial read is different from partial delivery (FRCTFPARTIAL), which allows delivery of fragments of an incomplete packet and thus potentially corrupted data. FLOWFRNOPART will never deliver corrupted data (unless FRCTFPARTIAL is also set). If FLOWFRNOPART is set and the buffer provided to flow_read is too small for the SDU, that SDU will be discarded and -EMSGSIZE is returned; Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Fix reading LSAs in link-state policy

2018-03-16T12:44:08+00:00

The read buffer had the exact length of a link-state message. With the partial read implemented, we should then do another read() to check if there are more parts of the message (which will return 0). To avoid the additional read() call every time, the buffer was extended by 1 byte. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Fix bytes sent in send statistics

2018-03-08T12:45:44+00:00

The number of bytes sent was not counting the data transfer PCI. This is now fixed. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Add fccntl operation to get queue lengths

2018-02-28T13:15:53+00:00

This adds the FLOWGRXQLEN and FLOWGTXQLEN operations to fccntl to get the number of packets that are in the receive and transmit buffers respectively. The flow statistics are updated to show these queue lengths. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders
