Description Richard Wai 2024-03-30 05:51:12 UTC 
Commit 713264f6b8bc5f927dd52cf8ffcccfa397034fec (March 6 2023) has potentially broken BOOTP/DHCP functionality for nfsroot diskless start-up.

This commit adds a check to the end of netinet/in_pcb.c:in_pcbladdr that checks for a source address equivalent to INADDR_ANY.

Unfortunately as part of the diskless BOOTP/DHCP process (nfs/bootp_subr.c et al), the interface's address is (effectively) set to INADDR_ANY, causing this check to fail, and therefore the DHCP search and the rest of the diskless nfs root process to fail as well.

Tested/discovered and analyzed on ARM64/RPI4, 14.0-RELEASE.

Not yet verified for other platforms.
