rng-tools missing and /dev/hwrng without driver
by SW＠EU 31 Oct '25

31 Oct '25

Hi, today I will report a problem that is released to ipa-server. This server contains a certificate authority and such service need many entropy. The default on CentOS 7 on a Banana PI is not enough, i.e. $(cat /proc/sys/kernel/random/entropy_avail) is less than 1000. I have solved this in meantime by installing and enabling of haveged from the EPEL repository. Normally it would be done by installing the rng-tools. But there are two problems: 1. The rng-tools was not in the repositories, so I have downloaded rng-tools-5-8.fc24.armv7hl.rpm because this are the same version which is included in CentOS 7.3 for x86_64. 2. This rng-tools are usable but the daemon starts and stops immediately with the following error message: # rngd -v /dev/hwrng: No such device /dev/tpm0: No such file or directory No entropy sources found, exiting This is not the problem of this binary it is a problem of the Kernel. /dev/hwrng exists and if I remove it then it reappears after reboot, but # ls -l /dev/hwrng crw-------. 1 root root 10, 183 1. Jan 1970 /dev/hwrng # udevadm info -a -n /dev/hwrng Udevadm info starts with the device specified by the devpath and then walks up the chain of parent devices. It prints for every device found, all possible attributes in the udev rules key format. A rule to match, can be composed by the attributes of the device and the attributes from one single parent device. looking at device '/devices/virtual/misc/hw_random': KERNEL=="hw_random" SUBSYSTEM=="misc" DRIVER=="" ATTR{rng_current}=="none" ATTR{rng_available}=="" there is no driver for this device. I have searched and found this link http://forum.lemaker.org/thread-23618-1-1.html which includes a link to the full story. If I read all right then on bananian /dev/hwrng appears only if the adapted or a more actual sun4i-ss.ko module is loaded (there is written: "module author has indicated this will be going into the mainline kernel shortly“). This module is also loaded on a Banana PI with current CentOS 7. So does the kernel of CentOS 7.3 for ARM32 include this patch and if yes why it does not work or otherwise why this device appears but has no driver?

EPEL repo not available?
by Boyd Ako 31 Oct '25

31 Oct '25

Can anybody verify that the EPEL repo for ARMHFP isn’t available? I keep getting an error saying the REPOMD file isn’t there when running yum. It works if I use —disablerepo=epel\* when using yum. But, there might be some stuff in the EPEL that I’m looking for. Running it on a Raspberry Pi 3 and trying to get Nagios installed for home use. Domo, Boyd H.

Gigabyte MP30-AR0
by Gordan Bobic 31 Oct '25

31 Oct '25

Hi, I am toying with the idea of getting a Gigabyte MP30-AR0 board (despite the insanely exorbitant price tag). Has anyone got the aarch64 CentOS working on one of those? Any special instructions? Also, if I get the ISO, is it bootable on aarch64? Does the installer work? Or does the image have to be used like on 32-bit ARM? Thanks. Gordan

Kubernetes support on ARM32
by Trunet 23 Feb '18

23 Feb '18

Hey, what's up! I finished building all needed packages to bring kubernetes to ARM. All of them were brought by simply copying src packages from CBS and doing minor or no changes at all. To my surprise, kubeadm ran perfectly fine, it got the correspondent arm image for each component. I went with weave for pod network layer, as it have network policy and ARM support. Manual changes, was to symlink all files under /opt/cni/bin into /usr/libexec/cni, otherwise the pods will not find the cni plugins and doesn't start (like kube-dns stuck at containercreating). And kubernetes-dashboard, you need to change tha image to be arm instead of amd64. Repo is here: [ https://armv7.dev.centos.org/repodir/community-kubernetes-testing/ | https://armv7.dev.centos.org/repodir/community-kubernetes-testing/ ] =================================== # kubectl version Client Version: version.Info{Major:"1", Minor:"9", GitVersion:"v1.9.3", GitCommit:"d2835416544f298c919e2ead3be3d0864b52323b", GitTreeState:"archive", BuildDate:"2018-02-22T14:26:58Z", GoVersion:"go1.9.2", Compiler:"gc", Platform:"linux/arm"} Server Version: version.Info{Major:"1", Minor:"9", GitVersion:"v1.9.3", GitCommit:"d2835416544f298c919e2ead3be3d0864b52323b", GitTreeState:"clean", BuildDate:"2018-02-07T11:55:20Z", GoVersion:"go1.9.2", Compiler:"gc", Platform:"linux/arm"} # kubectl cluster-info Kubernetes master is running at https://192.168.x.x:6443 KubeDNS is running at [ https://192.168.x.x:6443/api/v1/namespaces/kube-system/services/kube-dns:dn… | https://192.168.x.x:6443/api/v1/namespaces/kube-system/services/kube-dns:dn… ] To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'. =================================== Thanks for Arrfab for setting up the build environment and repository.

Docker support
by Trunet 20 Feb '18

20 Feb '18

Hello, I successfully built docker from SRPM, and it's working. =========================================================== # rpm -qa docker docker-1.12.6-71.git3e8e77d.el7.centos.1.armv7hl # docker run armhf/hello-world Hello from Docker on armhf! This message shows that your installation appears to be working correctly. To generate this message, Docker took the following steps: 1. The Docker client contacted the Docker daemon. 2. The Docker daemon pulled the "hello-world" image from the Docker Hub. 3. The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading. 4. The Docker daemon streamed that output to the Docker client, which sent it to your terminal. To try something more ambitious, you can run an Ubuntu container with: $ docker run -it ubuntu bash Share images, automate workflows, and more with a free Docker Hub account: https://hub.docker.com For more examples and ideas, visit: https://docs.docker.com/engine/userguide/ =========================================================== Fabian is pushing some patches needed to built all the dependencies. The list of SRPMS I had to rpmbuild are: container-selinux.spec container-storage-setup.spec docbook-style-dsssl.spec docbook-utils.spec docker.spec golang-github-cpuguy83-go-md2man.spec golang.spec gtk-doc.spec oci-register-machine.spec oci-systemd-hook.spec oci-umount.spec ostree.spec skopeo.spec Best regards, Wagner Sartori Junior

kernel 4.14.17 testing for armhfp boards (not for rpi2/rpi3)
by Fabian Arrotin 19 Feb '18

19 Feb '18

Hi, Some people asked for a newer 4.14 kernel recently as they'd like to test some boards, and not rely on the initial kernel provided by the vendor, so in fact relying on the mainline upstream kernel. As some boards received support in newer 4.14 branch (now also LTS) we're considering a bump from 4.9.x to 4.14.x branch for armhfp. Kernel 4.14.17-201.el7 was so built last week and is available in a testing repo : .repo file that can be created is : [kernel-testing] name=kernel-testing baseurl=https://armv7.dev.centos.org/repodir/arm-kernels/kernel/ enabled=1 gpgcheck=0 If you can give feedback that would be appreciated. So far it was tested on cubietruck and bananapi Cheers, -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 56BEC54E | twitter: @arrfab

configs directory, compiling a custom kernel for ARM
by Chris Szilagyi 17 Feb '18

17 Feb '18

Hello: I am following the CentOS instructions to compile a custom kernel for ARM. I am following the instructions here: https://wiki.centos.org/HowTos/Custom_Kernel. I do need my own config which I have generated and copied to the directories as mentioned in the instructions. I eventually get to the step and start the build with : rpmbuild -bb --target=`uname -m` kernel.spec 2> build-err.log | tee build-out.log During the build, just after the "make -s mrproper", it tries to "cp configs/kernel-4.9.75-armv7l.config", and gives the error "No such file or directory". It seems that the BUILD/kernel-*/linux-*configs/ directory is somehow being generated by some scripts, and the config I need is not there. I can't seem to find out where it gets the config files that it places in the configs folder. Can anybody shed some light on this? I noticed that the running kernel is "armv7hl", and doing a "uname -m" returns "armv7l" (missing the "h"). Not sure if this has anything to do with it. Thank you! Chris
