Eric Dumazet a3a128f611 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

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
