I'm not entirely sure this is related to systemd renaming interfaces, but it's the only thing I could think that is crashing it.

Every time my new system boots, dhcpcd sigsegvs and I have to log into the console and run systemctl start dhcpcd.

Log from journalctl:

So, having not installed Gentoo in probably about 3-4 years, how do I:

A. Prevent systemd from renaming my interface. I do not want to type eno16777736 every time. Sheesh.
B. Stop dhcpcd from crashing (maybe fixed by A?). I did try to follow some directions I saw on here from earlier this month and install dhcpcd 6.4 but the problem still persists.

Thanks!

Well, the udev plugin loaded and udev must have told dhcpcd that eth0 was stable which it obviously wasn't

Still, it should not have segfaulted.
Can you built with debugging enabled and provide a backtrace from a dhcpcd core dump please?

Haha, I think I finally figured this out. I set up kernel with CONFIG_COREDUMP, added the * soft core unlimited to limits.conf, updated the systemd service with LimitCORE=infinity, and set the sysctl settings for dumping the core of suid. Whew.

And just to double check, this is the proper debug config for building the package, right?
Code:
# cat /etc/portage/env/debug.conf
CFLAGS="${CFLAGS} -ggdb"
CXXFLAGS="${CXXFLAGS} -ggdb"
FEATURES="noclean nostrip splitdebug"
# cat /etc/portage/package.env
net-misc/dhcpcd debug.conf


And tada, I have a core dump. Only took me 2 hours :oops:

Code:
# gdb_get_backtrace `which dhcpcd` core.dump.1403951241.4491
[New LWP 4491]

warning: Could not load shared library symbols for linux-vdso.so.1.

Hmmmm, it shouldn't really be crashing there.
Can you add debug on a line by itself in /etc/dhcpcd.conf and provide another log snippet please so I can get more context?

Interesting.

So it looks like that udev lied that the device was ready and it issued an add and move call - only one should have been issued.
So I think it's caused by a udev bug.
However, dhcpcd still shouldn't segfault but I can't see what I'm doing wrong. I'll keep poking at it, but for the time being file a bug at bugs.gentoo.org

Can you test this patch please?
http://roy.marples.name/~roy/dhcpcd-ifdebug.diff

If it fails, some more dhcpcd debug output would be nice so I can see the new messages.

Or you can try the dhcpcd-9999 ebuild as I have committed a similar patch upstream.

So maybe the error is not tied to the renaming of the interface. Patch applied and still crashing. I'm doing an emerge @world right now to see if maybe something else is messed up.

Two new logs:

The IPv6 is new, and I have this new backtrace which happens in dhcpcd_startinterface (IPv6)

OK, fixed here I think: http://roy.marples.name/projects/dhcpcd/fdiff?v1=c2f0f356fbb7ba56801b45f38b52ac89976cca7d&v2=0e945dc9ec65fed2f41c0e27f80d9c8145cae181&sbs=0

Requires the previous patch as well.

Thanks! I was unable to apply the patch directly using the 6.4.0 codebase, so I switched to dhcpcd-9999 and the patch you have committed has not crashed in 4-5 reboots now.
