Cover letter [U-Boot] [PATCH 00/28] Add link-local addressing support
Quoted 5 lines · Joe Hershberger
Link-local support allows the bootloader to get a usable network address regardless of network environment. Given that bootloaders may not always have access to a DHCP server, this functionality makes accessing it in those environments easier. It is also referred to as zero-configuration IP.
Hi Joe,
I have a basic question about your patchset. RFC3927 requires that addresses are continuosly checked to avoid conflicts - this is a strict requirement.
However, it is clear we cannot comply with this requirement. The protocol runs once and there is not a background process to check for conflicts.
I can imagine we can get conflicts, when several targets are running at the same time in u_boot and they are attached to a network where local-link addressing is active. Then we can have two or more system using the same ip address, making the network unreliable.
Which are the limitations of this implementation ? They should also described in your patchset, maybe with a README file. Is is thought to connect the target directly to a PC ?
Best regards,
Stefano Babic
