dhcpcd crashes every 5 days. I tried saving a crash report by setting sysctl.kern.nosuidcoredump=2; however dhcpcd.core was not written to /var/crash/dhcpcd.
Here is some more information about my problem: https://marc.info/?l=openbsd-misc&m=167289142025844&w=2 Some other information not included in the above thread. According to dhcpcd.conf(5), there should be a file /var/db/dhcpcd/duid; however there is no such file nor has there ever been. It also states that the DHCPv6 client ID will be DUID+IAID; however they are the same according to dhcpcd -U em0: dhcp6_client_id=00041c021b030d04e70508065c0700080009 /var/log/daemon: dhcpcd[86796]: DUID 00:04:1c:02:1b:03:0d:04:e7:05:08:06:5c:07:00:08:00:09 The line in /etc/dhcpcd.conf that has always given me pause-since I haven't found examples on the Internet that use it-is the line: ia_pd 0/::/60. According to dhcpcd.conf(8), this should mean that a prefix should be delegated associated with the IAID 0 with prefix :: and prefix length of 60. Since there are no interfaces that follow, then dhcpcd should "assign a prefix to every other interface with a sla_id equivalent to the interface index assigned by the OS." However I explicitly deny all interfaces except em0-the interface requesting the prefix delegation-so this should mean that dhcpcd will assign a prefix to no other interface. I statically assign /64s from this /60 to my other interfaces. Perhaps dhcpcd requires assigning a prefix to at least one interface, but temporarily allows for it for like 5 days? Is there any use in building dhcpcd with debug symbols if dhcpcd.core is not being generated?
