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,
I am currently testing FreeBSD 14.0 Current
FreeBSD alfadev 14.0-CURRENT FreeBSD 14.0-CURRENT #1: Fri Sep 30 11:55:56 +03 2022
When machine has started I am getting Lock order reversal messages from kernel :

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?
Hello, i have a question about FreeBSD updates when using freebsd-update tool when you are running a custom kernel, in the documentation i can read:
When i compile my custom kernel, the GENERIC ends in /boot/kernel.old directory, i could copy to /boot/GENERIC to mantain a copy the first time...
Hi all,
I am trying to understand how FreeBSD's USB subsystem works and appear to be running into a kernel panic due to a failed assertion that I do not understand. the assertion in question is /usr/src/sys/dev/usb/usb_transfer.c:1954.
My understanding is that you first configure...
I know that FreeBSD distributes a generic kernel to support as many possible devices as possible. I also know I can compile my own target kernel with only my devices. What I would like to know is how small the kernel can get in theory before you start losing any serious functionality. Could it...
I'm currently working on a embedded project, and i'm trying to understand if it's possible to have a small /usr/src tree.
This source tree only has to contain the FreeBSD bootloader, kernel, kernel-modules, because the embedded application will replace /sbin/init.
So is is possible to have a...
