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

lib: Simplify some code in rdrbuff

This simplifies some functions in the rdrbuff. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

tools: Use non-blocking read in servers

2018-03-16T11:05:40+00:00

The oping and ocbr servers were using non-blocking read/writes. This caused writes to fail on high-performance tests if the buffer got full, instead of waiting for a slot in the buffer. The write failure caused the server to quit. This fixes the tools by setting the I/O to blocking write and non-blocking read. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Use sequenced datagrams with UNIX sockets

2018-03-13T16:08:52+00:00

The UNIX sockets were using SOCK_STREAM, which does not preserve the message boundaries. This switches to SOCK_SEQPACKET. Signed-off-by: Sander Vrijders Signed-off-by: Dimitri Staessens

lib: Allow partial read

2018-03-12T17:39:15+00:00

This implements partial read of packets if the buffer supplied to flow_read() is smaller than the packet in the buffer. If the number of bytes returned by flow_read equals the size of the buffer, the next read() will deliver the next bytes of the packet (or 0 if the packet was exactly the size of the buffer on the previous read). Implements #7. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Implement timeout on blocking write

2018-03-12T09:32:24+00:00

This completes the implementation of the SNDTIMEO for a blocking write. Fixes #6. 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.

lib: Use PTHREAD_COND_CLOCK for blocking reads

2018-03-10T12:01:23+00:00

The rbuff uses the PTHREAD_COND_CLOCK for its condition variables, but the flow_read was passing a time it got from the CLOCK_REALTIME_COARSE clock. This causes the blocking reads not to timeout correctly. The oping was updated to detect server timeouts and finish gracefully. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders
