MFp4: anchie_soc2009 branch: Add kernel side support for Secure Neighbor Discovery (SeND), RFC 3971. The implementation consists of a kernel module that gets packets from the nd6 code, sends them to user space on a dedicated socket and reinjects them back for further processing. Hooks are used from nd6 code paths to divert relevant packets to the send implementation for processing in user space. The hooks are only triggered if the send module is loaded. In case no user space application is connected to the send socket, processing continues normaly as if the module would not be loaded. Unloading the module is not possible at this time due to missing nd6 locking. The native SeND socket is similar to a raw IPv6 socket but with its own, internal pseudo-protocol.

- For kernel compiled only with KDTRACE_HOOKS and not any lock debugging option, unbreak the lock tracing release semantic by embedding calls to LOCKSTAT_PROFILE_RELEASE_LOCK() direclty in the inlined version of the releasing functions for mutex, rwlock and sxlock. Failing to do so skips the lockstat_probe_func invokation for unlocking. - As part of the LOCKSTAT support is inlined in mutex operation, for kernel compiled without lock debugging options, potentially every consumer must be compiled including opt_kdtrace.h. Fix this by moving KDTRACE_HOOKS into opt_global.h and remove the dependency by opt_kdtrace.h for all files, as now only KDTRACE_FRAMES is linked there and it is only used as a compile-time stub [0]. [0] immediately shows some new bug as DTRACE-derived support for debug in sfxge is broken and it was never really tested. As it was not including correctly opt_kdtrace.h before it was never enabled so it was kept broken for a while. Fix this by using a protection stub, leaving sfxge driver authors the responsibility for fixing it appropriately [1].
