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.

net: Pass kern from net_proto_family.create to sk_alloc

2015-05-11T14:50:17+00:00

In preparation for changing how struct net is refcounted on kernel sockets pass the knowledge that we are creating a kernel socket from sock_create_kern through to sk_alloc. Signed-off-by: "Eric W. Biederman" Signed-off-by: David S. Miller

Bluetooth: discard bt_sock_unregister() errors

2013-03-08T13:38:44+00:00

After we successfully registered a socket via bt_sock_register() there is no reason to ever check the return code of bt_sock_unregister(). If bt_sock_unregister() fails, it means the socket _is_ already unregistered so we have what we want, don't we? Also, to get bt_sock_unregister() to fail, another part of the kernel has to unregister _our_ socket. This is sooo _wrong_ that it will break way earlier than when we unregister our socket.
