dhcpcd-discuss

Hello

I'm testing/using dhcpcd 7.0.0 on Slackware64-current, mainly related to IPv6. I have seen 2 areas that may have some room for improvement:

- IPv6 autoconfiguration through the kernel is disabled by dhcpcd when it is started with the -4 flag. Also, when dhcpcd is started with the -6 flag, IPv4 configuration is altered. I have attached a diff of the sysctl before and after I run dhcpcd -4 wlan0. The diff is the same if I run dhcpcd -6 wlan0.

--> I'd expect configuration to be left alone for the protocol (IPv4/IPv6) that isnot used by dhcpcd.

- if dhcpcd is started with the -6 flag, it keeps running in the foreground after configuring the IPv6 address till it times out and exits. It doesn't fork to the background. I have a tcpdump of the router advertisement that I receive.

--> I'd expect dhcpcd to fork to the background after configuring the IPv6 addresses, so it can handle additional router advertisements

What is your opinion about these?

Thank you in advance.
