[SOLVED] DHCPCD Crash: Possibly net/dhcpcd port used for build is out-of-date compared to one in trueos-ports

[maxsteciuk]

On startup dhcp client using the dhcpcd binary which comes out of box crashes with segmentation fault due to nullptr dereference (ifp->options is null). This occurs at the IPv6 interface initialization stage. The version seems to be v6.11.5 (FreeBSD ports). The crash does not happen with dhcpcd v7.0.4 available in latest trueos-ports. As several smoke tests showed DHCP client successfully started.

So one possible solution is to build Trident with latest trueos-ports.

I noticed that trident-manifest.json has the following. Please confirm whether the directory contains latest from https://github.com/trueos/trueos-ports

"ports" : {
"type" : "local",
"url" : "/usr/ports_tmp",

Please see GDB for details on the issue if [necessary.

is this fixed with the latest release

No, unfortunately i still see dhcpcd segfaulting on startup

My guess is the following is culprit:

ifconfig_igb0="SYNCDHCP"
TODO: this line below
ifconfig_igb0_ipv6="inet6 accept_rtadv"

please try with new release

Hi
I just tried to restart network and fully reboot the system with the previously mentioned configs and dhcpcd didn't coredump

Thank you!

ifconfig_igb0_ipv6="inet6 accept_rtadv"
ifconfig_em0_ipv6="inet6 accept_rtadv"
