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: Add validity checks for eth-dix

2018-03-12T09:32:17+00:00

This will check if the Ethertype value is a valid Ethertype in the irm tool and the eth-dix IPCPd. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Add length field to eth-dix

2018-03-10T21:14:01+00:00

Some NICs added padding to the Ethernet II frames causing bad frame lengths and GPB unpack fails. This adds a 2-byte length field to the DIX frame to circumvent this. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Add IPCP over DIX Ethernet

2018-03-10T12:16:06+00:00

This adds an IPC Process that uses DIX Ethernet with an Ethertype that is configurable at bootstrap. This allows parallel DIX layers over the same Ethernet network with different Ethertypes (and one LLC layer). It allows jumbo frames in the future, and should avoid the problems we have with some routers not handling LLC traffic very well. The destination endpoint ID is sent as a 16 bit integer, so the maximum payload is 1498 bytes in standard Ethernet, and 8998 bytes when Jumbo frames are used. The implementation is very similar to the Ethernet LLC IPCP, so it is implemented using preprocessor macros in the single source instead of duplicating code.

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

ipcpd: Fix flow statistic

2018-02-26T10:35:56+00:00

There was a wrong rcv_bytes where it should have been snd_bytes. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Fix access to uninitialized value

2018-02-26T09:32:58+00:00

This fixes the access to an uninitialized dt_pci struct when updating flow statistics in the case there is no next hop, which often resulted in a segmentation fault. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Fix data race when accessing DHT state

2018-02-26T09:32:15+00:00

The dht_get_state() function should be used to get the state of the DHT. This fixes bug #4. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Fix malformed sprintf in dt component

2018-02-24T13:48:59+00:00

The sprintf was missing a format string. Some compilers did not complain about this. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders
