<p>Earlier today Linus Torvalds <a
href="https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=64edfa65062dc4509ba75978116b2f6d392346f5"
moz-do-not-send="true">merged</a> a pull request to <a
href="https://www.phoronix.com/news/Linux-7.1-Removes-Old-Net"
moz-do-not-send="true">remove AX.25 and hamradio subsystem
support from the Linux kernel</a>. While the headline sounds
ominous, most modern AX.25 implementations occur in software at
the user level without relying on the kernel level
implementation. <a href="https://github.com/wb2osz/direwolf"
moz-do-not-send="true">Direwolf</a>, for example, does not
require kernel level AX.25 support. Other software relying on
AX.25 may take advantage of dedicated AX.25 Python libraries.</p>
<p>The change comes as a result of AI based bug detection services
capable of identifying critical issues among code that may no
longer be maintained or utilized by end users. Torvalds <a
href="https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=64edfa65062dc4509ba75978116b2f6d392346f5"
moz-do-not-send="true">stated</a> that the amateur radio
related code in the Linux kernel no longer had any active
maintainers:</p>
<blockquote>
<p>Amateur radio did have occasional users (or so I think) but
most users switched to user space implementations since its
all super slow stuff. Nobody stepped up to maintain the kernel
code.</p>
</blockquote>
<p>According to <a
href="https://linux-commits-search.typesense.org/?commits%5Bquery%5D=ax25"
moz-do-not-send="true">typesense</a> the last Linux kernel
commit related to AX.25 was 6 years ago.</p>
<p>Additional code removed includes ISDN support, <a
href="https://en.wikipedia.org/wiki/Bus_mouse"
moz-do-not-send="true">bus mouse</a> support, and various
network drivers including support for old 3Com devices.</p>
