CAN stands for Controller Area Network, a broadcast network used
in automation and automotive fields. For example, the NMEA2000 standard
developped for marine devices uses a CAN network as the link layer.
This is an implementation of the linux socketcan API:
https://www.kernel.org/doc/Documentation/networking/can.txt
you can also see can(4).
This adds a new socket family (AF_CAN) and protocol (PF_CAN),
as well as the canconfig(8) utility, used to set timing parameter of
CAN hardware. Also inclued is a driver for the CAN controller
found in the allwinner A20 SoC (I tested it with an Olimex lime2 board,
connected with PIC18-based CAN devices).
There is also the canloop(4) pseudo-device, which allows to use
the socketcan API without CAN hardware.
At this time the CANFD part of the linux socketcan API is not implemented.
Error frames are not implemented either. But I could get the cansend and
canreceive utilities from the canutils package to build and run with minimal
changes. tcpudmp(8) can also be used to record frames, which can be
decoded with etherreal.
Since day0 pt_exec.c shipped with a dummy stub for "exec" operation, stop
waiting longer and eliminate it now. This functionality can be achieved
with filters.
Drop FreeBSD CVS repos references. There are certainly still some mirrors
or old mirrors available, but since the project moved to SVN+GIT entirely
drop it.
Add CVS Id - where missing - to the documentation files. This helps users
to determine how recent are the files.
- Expand the SMART / Health Information Log Page (Page 02) printout based on
NVM Express 1.2.1 Standard.
- Implement Intel-specific log pages.
- Implement HGST-specific log pages.
- Implement wdc-specific nvme control options.
- Add the ability to dump log pages directly in binary to stdout.
support for Endian-Independent FFS and Apple UFS is disabled unless FFS_EI=1
and APPLE_UFS=1 are added to CRUNCHENV, respectively.
This reduces the size of ramdisk image for atari by over 15KB.
Thanks tsutsui and christos for their useful comments.
