ax25: Fix std timer socket destroy handling.
Tihomir Heidelberg - 9a4gl, reports:
--------------------
I would like to direct you attention to one problem existing in ax.25
kernel since 2.4. If listening socket is closed and its SKB queue is
released but those sockets get weird. Those "unAccepted()" sockets
should be destroyed in ax25_std_heartbeat_expiry, but it will not
happen. And there is also a note about that in ax25_std_timer.c:
/* Magic here: If we listen() and a new link dies before it
is accepted() it isn't 'dead' so doesn't get removed. */
This issue cause ax25d to stop accepting new connections and I had to
restarted ax25d approximately each day and my services were unavailable.
Also netstat -n -l shows invalid source and device for those listening
sockets. It is strange why ax25d's listening socket get weird because of
this issue, but definitely when I solved this bug I do not have problems
with ax25d anymore and my ax25d can run for months without problems.
--------------------
Actually as far as I can see, this problem is even in releases
as far back as 2.2.x as well.
It seems senseless to special case this test on TCP_LISTEN state.
Anything still stuck in state 0 has no external references and
we can just simply kill it off directly.

rose: improving AX25 routing frames via ROSE network
ROSE network is organized through nodes connected via hamradio or Internet.
AX25 packet radio frames sent to a remote ROSE address destination are routed
through these nodes.
Without the present patch, automatic routing mechanism did not work optimally
due to an improper parameter checking.
rose_get_neigh() function is called either by rose_connect() or by
rose_route_frame().
In the case of a call from rose_connect(), f0 timer is checked to find if a connection
is already pending. In that case it returns the address of the neighbour, or returns a NULL otherwise.
When called by rose_route_frame() the purpose was to route a packet AX25 frame
through an adjacent node given a destination rose address.
However, in that case, t0 timer checked does not indicate if the adjacent node
is actually connected even if the timer is not null. Thus, for each frame sent, the
function often tried to start a new connexion even if the adjacent node was already connected.
The patch adds a "new" parameter that is true when the function is called by
rose route_frame().
This instructs rose_get_neigh() to check node parameter "restarted".
If restarted is true it means that the route to the destination address is opened via a neighbour
node already connected.
If "restarted" is false the function returns a NULL.
In that case the calling function will initiate a new connection as before.
This results in a fast routing of frames, from nodes to nodes, until
destination is reached, as originaly specified by ROSE protocole.

ax25: Use sock_graft() and remove bogus sk_socket and sk_sleep init.
The way that listening sockets work in ax25 is that the packet input
code path creates new socks via ax25_make_new() and attaches them
to the incoming SKB. This SKB gets queued up into the listening
socket's receive queue.
When accept()'d the sock gets hooked up to the real parent socket.
Alternatively, if the listening socket is closed and released, any
unborn socks stuff up in the receive queue get released.
So during this time period these sockets are unreachable in any
other way, so no wakeup events nor references to their ->sk_socket
and ->sk_sleep members can occur. And even if they do, all such
paths have to make NULL checks.
So do not deceptively initialize them in ax25_make_new() to the
values in the listening socket. Leave them at NULL.
Finally, use sock_graft() in ax25_accept().
