lib: Simplify delta-t logic

2018-06-05T12:04:45+00:00

This revises the delta-t implementation to align with Watson's timer specifications. FRCT will never deliver out-of-order packets. A raw flow (without delta-t state machine) will be able to provide such a service. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Add event types to fqueue

2018-05-14T09:40:09+00:00

The event type of the current event in the fqueue can now be requested using the fqueue_type() command. Currently events for packets (FLOW_PKT), flows (FLOW_UP, FLOW_DOWN) and allocation (FLOW_ALLOC, FLOW_DEALLOC) are specified. The implementation only tracks FLOW_PKT at this point.

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

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

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

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: 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: 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
