[Dnsmasq-discuss] ProxyDHCP mode is broken for serving ipxe.efi to UEFI pxe clents

[Dreamcat4]

Thanks Jarek!

Have tried your patch and switched to it in my auto builds now. Same
Bintray download URL as before:

https://dl.bintray.com/dreamcat4/linux/dnsmasq/

Re-formatted it so the patch will apply cleanly on v2.75 current release
version. Which is available here:

https://github.com/dreamcat4/docker-images/blob/master/linux-bin/dnsmasq/fix--dhcp-proxy-for-uefi-clients_02-mar-2016_jpolok.patch

The reason am using your patch now, is since you say it will be compatible
with more other uefi clients. So that is more good news to me. However it
is now necessary to add the following extra lines to dnsmasq.conf file.
Which is about this new option you added (skip menu). Otherwise uefi pxe
boot wont work at all. Like back to old days, where it just hangs, does
nothing like without any such uefi patch.

New lines to add to dnsmasq.conf:

pxe-skip-menu=X86-64_EFI
pxe-skip-menu=BC_EFI

The 2nd line was added for better compatibility (after other reports of
misbehaving clients), which is mentioned by David on other thread:

http://lists.thekelleys.org.uk/pipermail/dnsmasq-discuss/2015q4/010041.html


Anyway then it loads up the ipxe.efi. BTW, sorry for not being clear in my
previous mesg but the version of ipxe.efi have been testing with today is
v1.0.0+ (2d42d).

This lets me get forward enough to be encountering other bugs arounds
netbooting uefi. But those other new issue I am seeing now is nothing
related to dnsmasq itself. As that has finished / done its job by time of
those stages in the boot process.


Kind Regards
Dreamcat4
