inet: consolidate inet_csk_clone_lock()
Current inet_sock_set_state trace from inet_csk_clone_lock() is missing
many details :
... sock:inet_sock_set_state: family=AF_INET6 protocol=IPPROTO_TCP \
sport=4901 dport=0 \
saddr=127.0.0.6 daddr=0.0.0.0 \
saddrv6=:: daddrv6=:: \
oldstate=TCP_LISTEN newstate=TCP_SYN_RECV
Only the sport gives the listener port, no other parts of the n-tuple are correct.
In this patch, I initialize relevant fields of the new socket before
calling inet_sk_set_state(newsk, TCP_SYN_RECV).
We now have a trace including all the source/destination bits.
... sock:inet_sock_set_state: family=AF_INET6 protocol=IPPROTO_TCP \
sport=4901 dport=47648 \
saddr=127.0.0.6 daddr=127.0.0.6 \
saddrv6=2002:a05:6830:1f85:: daddrv6=2001:4860:f803:65::3 \
oldstate=TCP_LISTEN newstate=TCP_SYN_RECV
