[auth-options.c includes.h misc.c misc.h readconf.c servconf.c]
[serverloop.c ssh.c ssh_config.5 sshd_config.5 configure.ac]
two changes to the new ssh tunnel support. this breaks compatibility
with the initial commit but is required for a portable approach.
- make the tunnel id u_int and platform friendly, use predefined types.
- support configuration of layer 2 (ethernet) or layer 3
(point-to-point, default) modes. configuration is done using the
Tunnel (yes|point-to-point|ethernet|no) option is ssh_config(5) and
restricted by the PermitTunnel (yes|point-to-point|ethernet|no) option
in sshd_config(5).

Add support for tun(4) forwarding over OpenSSH, based on an idea and
initial channel code bits by markus@. This is a simple and easy way to
use OpenSSH for ad hoc virtual private network connections, e.g.
administrative tunnels or secure wireless access. It's based on a new
ssh channel and works similar to the existing TCP forwarding support,
except that it depends on the tun(4) network interface on both ends of
the connection for layer 2 or layer 3 tunneling. This diff also adds
support for LocalCommand in the ssh(1) client.
ok djm@, markus@, jmc@ (manpages), tested and discussed with others

fix regression I introduced in 4.2: X11 forwardings initiated after
a session has exited (e.g. "(sleep 5; xterm) &") would not start.

make ClientKeepAlive work for ssh -N, too (no login shell requested).
1) send a bogus channel request if we find a channel
2) send a bogus global request if we don't have a channel

replace fatal_cleanup() and linked list of fatal callbacks with static
cleanup_exit() function. re-refine cleanup_exit() where appropriate,
allocate sshd's authctxt eary to allow simpler cleanup in sshd.

[clientloop.c monitor.c monitor_wrap.c packet.c packet.h readconf.c]
[readconf.h serverloop.c sshconnect2.c]
rekeying bugfixes and automatic rekeying:
* both client and server rekey _automatically_
(a) after 2^31 packets, because after 2^32 packets
the sequence number for packets wraps
(b) after 2^(blocksize_in_bits/4) blocks
(see: draft-ietf-secsh-newmodes-00.txt)
(a) and (b) are _enabled_ by default, and only disabled for known
openssh versions, that don't support rekeying properly.
* client option 'RekeyLimit'
* do not reply to requests during rekeying

applied, but outside of ensure that smaller code bits migrated with

[auth1.c serverloop.c session.c session.h]
don't use channel_input_channel_request and callback
use new server_input_channel_req() instead:

[serverloop.c]
fix race between SIGCHLD and select with an additional pipe. writing
to the pipe on SIGCHLD wakes up select(). using pselect() is not
portable and siglongjmp() ugly. W. R. Stevens suggests similar solution.

[session.c session.h]
try to keep channels open until an exit-status message is sent.
don't kill the login shells if the shells stdin/out/err is closed.
this should now work:
ssh -2n localhost 'exec > /dev/null 2>&1; sleep 10; exit 5'; echo ?

close all channels if the connection to the remote host has been closed,
should fix sshd's hanging with WCHAN==wait
