| H A D | udp.c | d97106ea Sat Aug 09 02:35:05 CDT 2008 Herbert Xu <herbert@gondor.apana.org.au> udp: Drop socket lock for encapsulated packets
The socket lock is there to protect the normal UDP receive path.
Encapsulation UDP sockets don't need that protection. In fact
the locking is deadly for them as they may contain another UDP
packet within, possibly with the same addresses.
Also the nested bit was copied from TCP. TCP needs it because
of accept(2) spawning sockets. This simply doesn't apply to UDP
so I've removed it.
