Recently (since Yesterday ???) on at least one Fedora Linux 41 System (recently upgraded from Fedora Linux 40), dhcpcd (Version 10.0.8) is suddenly Crashing.

The Host is not getting a Global Unicast assigned IPv6 Address anymore from the Router (OPNSense).

The most intriguing Lines in the Logs are:

The Host is getting:

  • A Local-Link fe80: Type Address Configured
  • A Self-Configured (?) Global Unicast /128 Address Configured
  • A Self-Configured (?) Global Unicast /64 Address Configured

However, No Global Unicast Address, as Configured on the OPNSense Router, is getting assigned to the Interface anymore.

For some Reason, dhcpcd is crashing (Core Dump).

A similar Host running Debian Linux still (knock on Wood) has the IPv6 Address assigned, as configured on the OPNSense Router.

What I also don't understand is the "Connection refused". Is this indicating that there is another DHCP Client active on the Host ?

EDIT 1: the "Workaround" in Order to get back IPv6 Connectivity is to add a Static IPv6 Address in the Interface Section:

# Interface Configuration
interface enp6s18
        # Static IPv6 Configuration
        static ip6_address=2a0X:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX/64
        
        # Dynamic IPv6 Configuration using DHCPv6 Server
        # enable routing solicitation get the default IPv6 route
        ipv6rs

        # Request a normal (IA_NA) IPv6 address with IAID 1
        ia_na 1

        # Generate Stable Private IPv6 Addresses based from the DUID
        slaac private temporary

But it's a Lousy Workaround.

All Hosts running Fedora Linux 41 seem to be affected 😢.

@luckylinux can you test the master branch please, or the commit in e9e4040?

Right, but this patch deals exclusively with fedora 41 as an update to it breaks dhcpcd with privsep. And you note Fedora 41 in the title of this ticket and #405 is about arch linux and I don't know if they have updated their glibc yet.

@rsmarples: any specific Flags to use when building / configuring ?

From https://koji.fedoraproject.org/koji/buildinfo?buildID=2481527 and the SRC RPM, it would seem they use --dbdir=/var/lib/%{name} --runstatedir=%{_rundir} for Configure.

And the whole .spec File is:

Looks fine to me - most distros want to change the directories to their personal flavor.

OK quick & dirty (leaving the dhcpcd from Fedora installed via DNF as INSTALLED so I still have Access to the Systemd Service File), here is what I did:

git clone https://github.com/NetworkConfiguration/dhcpcd.git

# Not done, using "master" as suggested
# git checkout ...

cd dhcpcd

./configure --dbdir=/var/lib/dhcpcd
make
make install

I was now getting some "Permission Denied" and Looking at /var/log/audit/audit.log pointed to the "Usual" SELinux Issues, so add:

restorecon -rv /usr/share/dhcpcd/hooks
restorecon -rv /libexec/dhcpcd-hooks

But there is still something not right ...

Ah yes, also /libexec/dhcpcd-run-hooks is probably needed as well:

restorecon -rv /libexec/dhcpcd-run-hooks

But still Permission Denied 😞.

So it's definitively something that I overwrote during my make install ...

There is probably some /libexec/dhcpcd-run-hooks that needs to be configured correctly to end up in /usr/libexec/dhcpcd-run-hooks during ./configure to match how it was before.

Nevertheless a restorecon -rv /usr/libexec/dhcpcd-run-hooks didn't change anything 😢.

@rsmarples Trying with setenforce 0 seems to kinda work, except a 2nd Interface I use for Proxmox VE <-> KVM Virtual Machine for "direct" Private NFS doesn't seem to want to come up (static IPv4, all IPv6 disabled).

Furthermore I saw this in dmesg:

[ 1034.078303] dhcpcd[8477]: segfault at 20 ip 000000000042369b sp 00007ffe66953d10 error 4 in dhcpcd[2369b,400000+3e000] likely on CPU 6 (core 6, socket 0

EDIT 1: it was a Duplicate IP address (DAD), my Fault for that.

Still, there are some SELinux Issues that need to be sorted out ....

With setenforce 1 it just will NOT work 😞.

@rsmarples: any idea what is missing to get SELinux to work with dhcpcd with this Patch/Master Branch install applied ?

Thanks 😃

No idea sorry and I don't have time for dhcpcd right now as I'm in the middle of moving house.

Yeah that's definitively a huge amount of Work. I moved far too often up until recently so I hope I don't have to go through that again.

Courage 👍

Somehow I'm managing with NetworkManager for the Time being, otherwise I'll hack something in BASH Script and Systemd Services instead.

Thanks for your Help
