I think you are right. `strlcpy` is only supposed to copy `n-1` bytes from src to dest.

FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms.
A large community has continually developed it for more than thirty years.
Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.

Additional copyright information also exists for some sources in this tree - please see the specific source directories for more information.
The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree.
See build(7), config(8), FreeBSD handbook on building userland, and Handbook for kernels for more information, including setting make(1) variables.

In The Ampere Altra Review: 2x 80 Cores Arm Server Performance MonsterI used to use linux's list.h quite a bit, that is the "good taste" implementation, where the head is the same as the elements. My only problem with that implementation is the fact it is non-typed. Heads are generic, and the code using them has to use container_of() macros to recover the containing type.
I've since discovered bsd/queue.h [0], which is very similar in purpose, but is not "good taste" (which I don't mind at all) on the other hand it is type safe, has quite a few variants for single and double lists, and oh also, it's not GPL.

In The great Internet TCP congestion control censusIt seems like most of the discussion on HN is meta-discussion about FreeBSD in general, rather than this particular cheatsheet. I like FreeBSD, but I wouldn't really recommend this particular cheatsheet. Why? Some examples from the top (and if the top of the cheatsheet is problematic, it's not a useful quick reference IMO):
1. mount_msdosfs: The 'ad' name is largely historical; you'll see 'ada' and 'da' these days (the latter for USB drives)[1].
2. ISO9660 is also basically historical at this point; UDF is more likely. And it's useful to split out mdconfig (memory disk config) as its own command -- it's useful in a lot of contexts, and separating it might make that more obvious to someone reading.
3. Linux procfs and Linux procfs? This is confusing and doesn't help users looking to run Linux programs (a lot more work is needed; see [

2]). Creating /proc because it doesn't exist is odd; the directory should exist in FreeBSD installations and images, regardless of whether procfs is mounted[3].
Get what you will from the document; if it helps you, great.

In I’m A Teapot – HTTP status code 418There is nothing specific about system calls that increases the attack surface. Individual sysctls, files in procfs, sysfs, ioctls, etc. are all separate attack vectors.
The last time I checked, FreeBSD's list of system calls was larger than Linux's. This is because Linux tends to expose more functionality through sysfs, procfs, ioctl, while FreeBSD uses dedicated system calls.
https://filippo.io/linux-syscall-table/ <- max = 313
https://github.com/freebsd/freebsd/blob/master/sys/kern/sysc... <- max = 576, 356 marked 'STD'
In Implementing a System Call for OpenBSDWhich BSDs did you try and what is the precise behavior of subnet mask parameters that you had a problem with? It would be best if you could include the exact ifconfig command, the output from running the command and what was the expected outcome.
1) Yes, there is active development. BSDs don't have net-tools as a separately developed package.

https://github.com/freebsd/freebsd/commits/master/sbin/ifcon...
In Questions: History of Ifconfigdidn't go too deep on the code spelunking, but v7 Unix (and 2BSD) used 'swapping' rather than paging, where the whole process was moved in/out of RAM, 32V (32bit v7 for the vax by AT&T) kept this, 3BSD (32V++ in a way) added paged memory, and this was reworked in 4.3BSD (see 44doc newvm), Mach VM, etc.
can confirm SEGV is in v7 signal.h from 1979:
https://www.tuhs.org/cgi-bin/utree.pl?file=V7/usr/include/si...
where it is happily #defined as 11, and continues as such to this day:
https://github.com/freebsd/freebsd/blob/master/sys/sys/signa...
(etc, in the other BSD-derived systems)

But nowadays people expect to provide actual font files for weight and slant changes, as boldface is not actually overprinting and italics are not oblique. This starts to matter at cell sizes bigger than 8 by 8, and it isn't an 8 by 8 world nowadays. You'll notice that my terminal emulator reads different font files for bold/faint/italic combinations if they are given. (On one test machine I am currently feeding it a combination of UbuntuMono-i and UbuntuMono-n, with unscii-16-mini and Unifont 7 as fallbacks.)

It is not alone. The FreeBSD kernel's newer built-in terminal emulator (vt) loads two fonts, one for normal (medium) weight and one for boldface.

They could even do it with less churn, because of https://github.com/freebsd/freebsd/blob/master/sys/conf/opti... FreeBSD easily achieves binary compatibility with earlier versions. So no need to mess around with DKMS or their own thing. Or at least less so.
