tools: Increase read buffer in ocbr server

2018-03-25T10:15:03+00:00

The ocbr server had a 1500 byte read buffer, which caused it to perform partial reads on larger SDUs, slowing it down considerably when sendin large packets. The buffer has been increased to 512KB, partial reads disabled, and the client will give an error when larger frames are sent. It will also warn if the size overflows (avoiding a SEGV).

irmd: Fix memleak when failing to list ipcps

2018-03-22T15:29:06+00:00

The list_ipcps call had a memleak in the failure case. Also fixes a compiler warning for a possible uninitialized variable and renumbers the gpb ipcpd message fields. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Simplify reg/unreg API

2018-03-22T11:36:58+00:00

The reg/unreg API is simplified to registering and unregistering a single name with a single IPCP. The functionality associated with registering names was moved from the IRMd to the irm tool. The function to list IPCPs was simplified to return all IPCPs in the system with their basic properties needed for management. The above changes led to some needed changes in the irm tool and the management functions that were depending on the previous behaviour of list_ipcps. Command line functionality to list IPCPs in the system is also added to the irm tool. Some older code was refactored. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

tools: Fix help information for oecho

2018-03-19T09:29:09+00:00

The oecho tool still used its old "echo-app" name in the usage() output. The destination name is also changed to oecho. 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

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
