From Roland Knall:

From Roland Knall:
- Renaming opensafety.msg.type to opensafety.msg.direction
- Introducing real opensafety.msg.type as opensafety.msg.category and generated
field
- Adding openSAFETY Sender and Receiver field, for all types of messages
- Adding openSAFETY Domain number and Node number as generated fields, which
allows filtering for them
- Rework PACKET_RECEIVED_BY and PACKET_SEND_FROM_TO_ALL to PACKET_RECEIVER and
PACKET_SENDER
- Replaced PACKET_SEND_FROM_TO with calls to PACKET_RECEIVER and PACKET_SENDER
- Added functions, so that the new sender and receiver fields as well as
network information are added as sub-trees
- Removed DISSECTOR_ASSERT in opensafety_get_scm_udid as it is not needed here
anymore
- Added the connection valid bit to the dissection tree ( has been there as
message type, but was never validated )
- Added calculations for Domain Network Addr, depending if a valid UDID for the
SCM is present in SSDO and SPDO
- Corrected error, where sub-tree for spdo dissection used global ssdo_tree
instead of spdo_tree
- Added "Message Type unknown" which leads to PI_MALFORMED marked entry in
dissect_opensafety_message
- Added check for ( length - frameOffset ) is below or equal zero, to avoid
using dissector asserts
- Added check for freak frame start detection, where both frame starts would be
equal (could happen during fuzztest)
- Removed DISSECTOR_ASSERT for both frame starts being different
- Added check, that if the frame address is above 1024, the package get's
marked as PI_MALFORMED (fuzztest)
- Fixed CID 1215, CID 1224 and CID 1246/1247
- Corrected naming issue with openSAFETY/SercosIII dissection using UDP
transport
