2020-01-09socketcan-bcm: Fix wrongly opened socketRomain Forlot1-0/+1
This commit fixes a problem once a bcm socket has been opened but the following ioctl failed. Before we still return the socket number instead of returning a negative value as error. This resulted in problem because the subscription was considered as valid and binding was continuing using the closed file descriptor.

2020-01-09converter: Use unsigned int whenever it's possibleRomain Forlot2-3/+9
Use unsigned int whenever it is possible instead of uint32_t. This let the compiler decide the type. We do not need to use uint32_t explicitly for the converter. Bug-AGL: SPEC-2988 Change-Id: Ic2af875e7435668928c454df76e59c5c43b08407 Signed-off-by: Romain Forlot <romain.forlot@iot.bzh>

2018-12-14Smalls improvementsRomain Forlot2-3/+14
- Improve robustness reading a BCM socket Adding checks on system calls and remove the initialization of the struct that will hold the received message, not so much needed in that case. - More accurate log message at subscription/unsubscription step whether this is a FD CAN messages or not and if this a subscription or an unsubscription that is requested. - Initialize the full struct of vehicle message to avoid memory warning about conditionnal jump based on uninitialized bytes. - Memleak: Free raw pointer on active diagnostic requests Change-Id: I4bbf4d851c0fa1efdb6fa6034fac3d1dcafa1a73 Signed-off-by: Romain Forlot <romain.forlot@iot.bzh>
2018-12-14CAN FD implementationRomain Forlot2-20/+30
Add a flag to CAN message definitions which set the message as using FD protocol if true. Use a new generated file with the new FD flag field on the message definitions. Change BCM socket "struct" using an union to store the CAN frames either using the FD struct or the classic non FD struct. A BCM socket can only one frame type once configured. Use as much as possible the "struct canfd_frame" in the binding and only make a difference before writing or reading the socket. From a memory point of view both struct are identical and only the last member differ and could hold more data with messages of 64 bytes long. So the canfd_frame is compatible with the can_frame and can be differentiated by a flag set in the can_id member. Remove now unused code processing can_frame. Keep the diagnostic manager using the classic CAN frame. Set the maximum number of frames that a BCM socket can handle to 257.
