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.

parport: Remove parport_driver.devmodel

'devmodel' hasn't actually been used since: 'commit 3275158fa52a ("parport: remove use of devmodel")' and everyone now has it set to true and has been fixed up; remove the flag.

hamradio: use ndo_siocdevprivate

2021-07-27T19:11:44+00:00

hamradio uses a set of private ioctls that do seem to work correctly in compat mode, as they only rely on the ifr_data pointer. Move them over to the ndo_siocdevprivate callback as a cleanup.

Annotate hardware config module parameters in drivers/net/hamradio/

2017-04-20T11:02:32+00:00

When the kernel is running in secure boot mode, we lock down the kernel to prevent userspace from modifying the running kernel image. Whilst this includes prohibiting access to things like /dev/mem, it must also prevent access by means of configuring driver modules in such a way as to cause a device to access or modify the kernel image. To this end, annotate module_param* statements that refer to hardware configuration and indicate for future reference what type of parameter they specify. The parameter parser in the core sees this information and can skip such parameters with an error message if the kernel is locked down. The module initialisation then runs as normal, but just sees whatever the default values for those parameters is. Note that we do still need to do the module initialisation because some drivers have viable defaults set in case parameters aren't specified and some drivers support automatic configuration (e.g. PNP or PCI) in addition to manually coded parameters. This patch annotates drivers in drivers/net/hamradio/.

hamradio: baycom: fix old-style declaration

2016-06-17T05:06:30+00:00

Modern C standards expect the '__inline__' keyword to come before the return type in a declaration, and we get a warning for this with "make W=1": drivers/net/hamradio/baycom_par.c:159:1: error: '__inline__' is not at beginning of declaration [-Werror=old-style-declaration] For consistency with other drivers, I'm changing '__inline__' to 'inline' at the same time.
