[genivi-dlt] secure DLT daemon implementation

Hello Anooj,

Thanks a lot for your reply.
The mentioned fifo is the named pipe /tmp/dlt,  right?
Do you have any recommendations regarding  unix socket /tmp/dlt-ctrl.sock that seems to be used by the DLT daemon
to send control messages to the DLT lib client e.g. about allowed log level change?
Also could you tell me what's the purpose of the folder /tmp/dltpipes/ with named pipes?

Thank you in advance.


Best regards,
Oleksandr Popov

Hi,

Well that is right. Security has to be considered.
dlt daemon has to run with a special user. This user should be the only one with read permission from the fifo (IPC between dlt lib and daemon).

Hi all,

According to https://at.projects.genivi.org/wiki/display/PROJ/Diagnostic+Log+and+Trace, the DLT is developed with accordance to AUTOSAR standards and as a result, it doesn't care about any security.
To use the DLT during production phase, it would be great to have security mechanisms implemented,
e.g to prevent DLT library clients from affecting/sniffing other clients and the DLT daemon.
Do you have any secure DLT implementation/features for using on non-AUTOSAR Linux systems?

Thank you in advance.


Best regards,

Oleksandr Popov
