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

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 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

tools: Don't cancel reader thread in oping

2018-03-05T09:43:30+00:00

The reader thread was cancelled as soon as the writer was finished, which resulted in missed responses and misreported packet loss. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

build: Allow out-of-tree build of tools

2018-02-14T16:58:51+00:00

This removes the dependencies for the tools on some ouroboros internal headers (endian.h and time_utils.h) so they can be built out-of-tree. The echo-app tool has been renamed oecho and the cbr tool has been renamed ocbr. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Revise Data Transfer component

2018-02-13T18:15:07+00:00

This makes the TTL non-optional and allows the maximum (initial) value of the TTL to be specified at bootstrap (the default is set to 60). The fd in the DT PCI is now called EID (Endpoint ID). The names "dif" and "ae" have been replaced by "layer" and "component" respectively in all sources. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

build: Use GNUInstallDirs instead of hardcoded values

2018-02-06T17:27:38+00:00

This changes the build to use GNUInstallDirs instead of hardcoded values. Package maintainers can then override these defaults by passing the correct value to cmake on the command line. Signed-off-by: Sander Vrijders

tools: Fix check for return value in irm tool

2018-02-03T21:59:35+00:00

A check was done in the irm tool for the pid of a newly created IPCP, but it didn't catch all failures, this fixes that. Signed-off-by: Sander Vrijders Signed-off-by: Dimitri Staessens
