net: remove ISDN subsystem and Bluetooth CMTP

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

Remove the ISDN (mISDN, CAPI) subsystem and Bluetooth CMTP protocol from the kernel tree. ISDN is a pretty old technology and it's unclear whether anyone still uses it. I went over the last few years of git history and all the commits are either tree-wide conversions or syzbot/static analyzer fixes. When we discussed removal in the past IIRC there were some concerns about ISDN still being used in parts of Germany. Unfortunately, the code base is quite old, none of the current maintainers are familiar with it and AI tools will have a field day finding bugs here. Delete this code and preserve it in an out-of-tree repository for any remaining users: https://github.com/linux-netdev/mod-orphan UAPI constants AF_ISDN/PF_ISDN and the SELinux isdn_socket class are preserved for ABI stability, but the rest of uAPI is removed.

isdn: whitespace coding style cleanup

2012-02-21T17:04:01+00:00

isdn source code uses a not-current coding style. Update the coding style used on a per-line basis so that git diff -w shows only elided blank lines at EOF. Done with emacs and some scripts and some typing. Built x86 allyesconfig. No detected change in objdump -d or size. Signed-off-by: Joe Perches

mISDN: Fix TEI and SAPI handling

2009-05-25T07:51:35+00:00

Added SAPI value to use SAPIs different than 0. Now fixed TEIs work in NT mode. This allows PTP endpoint to be connected to PTMP ports together with other PTMP endpoints. New enhanced version, thanks to Sam Ravnborg for the hints. Signed-off-by: Andreas Eversberg Signed-off-by: Karsten Keil Signed-off-by: David S. Miller
