[Bug 1188019] New: Wicked CPU High on RaspberryPi 2
http://bugzilla.opensuse.org/show_bug.cgi?id=1188019 Bug ID: 1188019 Summary: Wicked CPU High on RaspberryPi 2 Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.2 Hardware: armv7 OS: openSUSE Leap 15.2 Status: NEW Severity: Normal Priority: P5 - None Component: Network Assignee: screening-team-bugs@suse.de Reporter: opensuse@wolke7.net QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Hello, I installed OpenSUSE 15.2 in Raspberry Pi 2, and "/usr/sbin/wickedd --systemd --foreground" always costs around 51% CPU in idle. This happens both in ethernet or with USB wifi dongle. If I use Raspberry Pi's default OS Raspbian, there is no such a problem. I have tried "sudo zypper update" it doesn't work. The internet is gotten by DHCP from home router. see below output from htop:

Now this problem still happens. Is my Raspberry Pi broken? Let me update the system / Switch back again to Raspbian to see. -- You are receiving this mail because: You are on the CC list for the bug.

First, my rpi2 is Raspberry Pi 2 Model B Rev 1.1, which use a different CPU from Rev 1.2. 2. I reinstall Raspbian Buster lite, there is no this problem (using DHCP). So my rpi2 is not broken. 3. Then I reinstall to OpenSUSE 15.3 (openSUSE-Leap-15.3-ARM-JeOS-raspberrypi2.armv7l-2021.05.31-Build8.1.raw.xz) If I use DHCP, there are huge of logs like these, and CPU still very high from wicked:

So I set static IP to this rpi2:
cat /etc/sysconfig/network/ifcfg-eth0 IPADDR='192.168.60.120/24' BOOTPROTO='static' STARTMODE='auto'
cat /etc/sysconfig/network/ifroute-eth0 default 192.168.60.21 - eth0
Then the CPU comes to 0 now. :) and "journalctl -n 10" do not show these DHCP infos. So, somethings wrong with wicked dhcp? Or is it normal that wicked will cause high CPU when request DHCP? -- You are receiving this mail because: You are on the CC list for the bug.

Yes, as it it seems, there is an issue with infinite lease time (4294967295 is UINT_MAX) :-/ (In reply to Ivan Ivanov from comment #4)

This is a different issue, please open a new report about. Either the router IPv6-RA� or the local config says, wicked should use DHCLIENT6_MODE=managed to acquire an IPv6 address, but the dhcp6 server isn't acting in managed but in info-only mode and delivers a lease without any IP; wickedd-dhcp6 has to discard / ignore such responses by RFC. Please install the "radvd" package and let "radvdump" running for a while to see the RA that arrives on the interface(s) or capture dhcp6 and icmp6 (contains router RS/RA) packets, using tcpdump: tcpdump -w dhcp6.pcap -s 65535 -Uvnfi any 'icmp6 or port 546 or port 547' while `wicked ifup all` (=rcnetwork start) is running. In both cases, please provide logs as described at: https://en.opensuse.org/openSUSE:Bugreport_wicked -- You are receiving this mail because: You are on the CC list for the bug.
