Oliver Hartkopp 13dc8e9cc5 isobusfs: srv: check name length against the received message length 
The Change Current Directory and Volume Status requests used the path
and volume name length from the request without checking it against
the received message length. Short messages with a big name length made
the server process stale content of the receive buffer as path or
volume name.

Check the name length against the message length, use le16toh() for the
CCD name length and fix the debug output of the volume name.

Oleksij RempelandOleksij Rempel 42edaeaf52 Implement ISOBUS File Server (FS) Interface as a Personal Project 
Introduce the ISOBUS File Server (FS) interface, compatible with ISO
11783-13. The implementation utilizes the kernel's existing CAN J1939
socket support.

For testing following setup can be used:
ip link add type vcan
ip l s dev vcan0 up

j1939acd -r 64-95 -c /tmp/1122334455667788.jacd 1122334455667788 vcan0 &
j1939acd -r 96-127 -c /tmp/1122334455667789.jacd 1122334455667789 vcan0 &

sleep 1

isobusfs-srv -i vcan0 -n 1122334455667788 -v vol1:/path/to/export/
isobusfs-cli -i vcan0 -n 0x1122334455667789 -m 0x1122334455667788 -I

Interactive mode currently support following commands:
exit - exit interactive mode
quit - exit interactive mode
help - show this help
dmesg - show log buffer
selftest - run selftest
ls - list directory
ll - list directory with long listing format
cd - change directory
pwd - print name of current/working directory
get - get file
