net: remove ax25 and amateur radio (hamradio) subsystem

2026-04-23T17:24:02+00:00

Remove the amateur radio (AX.25, NET/ROM, ROSE) protocol implementation
and all associated hamradio device drivers from the kernel tree.
This set of protocols has long been a huge bug/syzbot magnet,
and since nobody stepped up to help us deal with the influx
of the AI-generated bug reports we need to move it out of tree
to protect our sanity.

The code is moved to an out-of-tree repo:
https://github.com/linux-netdev/mod-orphan
if it's cleaned up and reworked there we can accept it back.

Minimal stub headers are kept for include/net/ax25.h (AX25_P_IP,
AX25_ADDR_LEN, ax25_address) and include/net/rose.h (ROSE_ADDR_LEN)
so that the conditional integration code in arp.c and tun.c continues
to compile and work when the out-of-tree modules are loaded.

Documentation: use a source-read extension for the index link boilerplate

2026-01-23T18:59:34+00:00

The root document usually has a special :ref:`genindex` link to the
generated index. This is also the case for Documentation/index.rst. The
other index.rst files deeper in the directory hierarchy usually don't.

For SPHINXDIRS builds, the root document isn't Documentation/index.rst,
but some other index.rst in the hierarchy. Currently they have a
".. only::" block to add the index link when doing SPHINXDIRS html
builds.

This is obviously very tedious and repetitive. The link is also added to
all index.rst files in the hierarchy for SPHINXDIRS builds, not just the
root document.

Put the boilerplate in a sphinx-includes/subproject-index.rst file, and
include it at the end of the root document for subproject builds in an
ad-hoc source-read extension defined in conf.py.

For now, keep having the boilerplate in translations, because this
approach currently doesn't cover translated index link headers.
