Hi all,
I'm currently running FreeBSD 14.0 on a VPS (by Contabo):
# uname -a
FreeBSD host 14.0-RELEASE-p11 FreeBSD 14.0-RELEASE-p11 #0: Wed Sep 18 23:01:59 UTC 2024 root@amd64-builder.daemonology.net:/usr/obj/usr/src/amd64.amd64/sys/GENERIC amd64
I have been using FreeBSD for years and I...
Hello, I am doing kernel development and would like to debug my version of the kernel. Can I do that with the help of debugger and bhyve, to run in a containerized environment? Thanks.
I'm trying to reach a point where I can do online debugging with kgdb of the FreeBSD kernel and it's modules in order to learn more about the system and take on a small projects in the system development. I have searched through the whole internet for the complete guide on how to do it however...
Hi,
I am new to FreeBSD and use it at work. We use a stripped version of FreeBSD11.4-RELEASE (the person that stripped it is not around) and so, do not hesitate to tell me what "might" be missing or what "might" be different in our stripped version.
I need to mount a FAT32 usb stick.

I have updated my system from 13.2-RELEASE -> 14.0-RELEASE, I use a custom kernel configuration in order to have network interface polling enabled, yet when I have tried to recompile my custom kernel with 14.0 version I noticed that releng/14.0 is not present in Git repository.
Now I have my...
I am looking for a way to change the gid of the dynamic linker while it is reading shared objects from the filesystem. For context, my goal is to create an environment where an unprivileged user can not read/analyze ELF files but can still execute them. This can be easily implemented for ELF...
I am running a system with TrueNAS-13.0-U6.1, which currently is the most recent release. This is based on FreeBSD 13.1 (which is EOL):
# uname -a
FreeBSD storage.example.com 13.1-RELEASE-p9 FreeBSD 13.1-RELEASE-p9 n245429-296d095698e TRUENAS amd64
This is a bit of a shame (it tends to happen...
Hi all!
Is it possible to load the wg-interface configuration through a setting in rc.conf without using the devd hook?
On FreeBSD v.14 my wireguard service run under that config:
# cat /boot/loader.conf | grep wg
if_wg_load="YES"
#
# cat /etc/rc.conf | grep wg
cloned_interfaces="wg"...
Hi all,
Somewhere in my code the member of a struct is changed but I can't seem to find where. I want to use ddb's watch feature but can't figure out how to pinpoint a memory address.
I cam find the softc address via 'show all devices', but i cannot figure out how to print the equivalent of...
Hi. I made a custom kernel by copying GENERIC to a new file called MYKERNEL and I built kernel with KERNCONF=MYKERNEL. My problem is when i commented out those two lines below, make buildkernel command fails with errors. If I don't comment out these lines, make doesn't fail. I would want to know...
I recently set up a bhyve vm on my workstation for kernel development and figured others might be able to make use of my notes as well, because it's really quite easy.
VM setup
Download a FreeBSD disk image, i.e. 13.2-RELEASE if you're running 13.2. This version should match whatever kernel...
I've done some updates to my packages and recently upgraded from 13.2-p3 to p4 and noticed that when I reboot or turn on from a cold boot, savecore saves a core dump for some reason.
The system appears perfectly normal the rest of the time; it has no apparent panic during the...
Hi, I have installed FreeBSD on an amd64 laptop, and the only issue with it is an apparently long-standing bug in support for eMMC storage (https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=211705#c3), which I would like to investigate. But I'm stuck even getting an unmodified but locally...
Guys, good evening folks.
My setup is: I build world and kernel (Generic) on my host and I use poudriere to build all ports that I use (around 1200). I want to play with the Kernel configuration and build a custom kernel for my T430. For now I don't want to put any port module inside the...
I was having the known problem with Text Console using CTRL + ALT + F1-F8 bug of tearing / square pixelated screens.
I am currently still trying/testing with some options in /boot/loader.conf file to see if I can fix this issue of the tearing with Nvidia drivers 510.60.2.
Similar to...
As stated in the title, I would like to change the kernel of my Unix build from FreeBSD to NetBSD, as I prefer the philosophy of the rump kernel to that of a monolithic, but prefer the lexicography and semantics of FreeBSD's system applications. The current build is FreeBSD, with only sudo...
Hi,

Hi,
Historically yarrow algorithm had a kernel process with the name of yarrow. But after replacing it with Fortuna, the kernel process disappears.
What is the name of the new kernel process of Fortuna's algorithm in the permanent kernel processes?
