dhcpcd connection refused

[ghost]

in addition to the apparmor issues the recent update also seems to break it in a tty logged in as root

ps_dostop: Connection refused

downgrading this crap fixed the problem

was only able to find a single reference to my problem by someone else: https://bbs.archlinux.org/viewtopic.php?id=254935

this is with apparmor installed?

[ghost]

no apparmor, it's a fresh system with nothing but lvm2 and crypsetup with efi

rd.auto=1
cryptdevice=UUID=<UUID>:lvm
ipv6.disable=1
net.ifnames=0

dhcpdcd also says "connected to access point 'xxx'"

with wpa_supplicant set up correctly and running

dhcpcd was also working fine when setting everything up from the live system, no surprise since it's an older version

the system in question does have one of those 32 bit EFI firmwares with a 64 bit CPU, no idea if it's related. After installing grub-x86_64-efi initially i also had to install grub-i386-efi

grub-install --target=i386-efi --efi-directory=/boot/efi --bootloader-id=void_grub --boot-directory=/boot --recheck --debug

does not seem to be related to root
same problem with a normal user

first 'ip a' shows no ip for wlan0 despite /var/service/dhcpcd-wlan0

then sudo dhcpcd wlan0 shows the connection refused

[ghost]

solution:

dhcpcd -4

from https://bbs.archlinux.org/viewtopic.php?id=254888

confirmed as working for me, no idea what -4 does

[Vaelatern]

it disables ipv6

[Piraty]

i start my systems with cmdline= ... ipv6.disable=1 and had to add ipv4only to /etc/dhcpcd.conf, else it crashed after getting a lease from the router.
This wasn't required before and the logs of dhcpcd were pretty clear about why it crashed, so the fix was easy.

[Piraty]

clearly an upstream issue

[ErinVoid]

Have been having random dhcpcd issues on a standard-ish x64 musl install. Works one minute, not the next. Added noarp to dhcpcd.conf and the issue disappeared at the same time but cannot validate it was specifically that.

[Piraty]

i can confirm that dhcpcd-9.0.2 solves it. it no longer requires ipv4only in the conf file to work.

probably NetworkConfiguration/dhcpcd@717e041
