247284481c Kill some obsolete sub-thread-ptrace stuff
There is a couple of subtle checks which were needed to handle ptracing from
the same thread group. This was deprecated a long ago, imho this code just
complicates the understanding.

And, the "->parent->signal->flags & SIGNAL_GROUP_EXIT" check in exit_notify()
is not right. SIGNAL_GROUP_EXIT can mean exec(), not exit_group(). This means
ptracer can lose a ptraced zombie on exec(). Minor problem, but still the bug.

from non __init code (eg. hotpluggable serial ports like serial_cs) so
remove the __init from the call chain to avoid crashes.

tcp_cwnd_down must check for it too as it should be conservative

Note:
- Separated also is_dupack and do_lost in fast_retransalert

	* This time it really fixes cumulative ACK with many new
	  SACK blocks recovery entry (I claimed this fixes with

	  tcp_update_scoreboard regardless of is_dupack when
	  in recovery as long as there is enough fackets_out.

4a4b6271a8 [PF_KEY]: Fix ipsec not working in 2.6.23-rc1-git10
Although an ipsec SA was established, kernel couldn't seem to find it.

I think since we are now using "x->sel.family" instead of "family" in
the xfrm_selector_match() called in xfrm_state_find(), af_key needs to
set this field too, just as xfrm_user.

In af_key.c, x->sel.family only gets set when there's an
ext_hdrs[SADB_EXT_ADDRESS_PROXY-1] which I think is for tunnel.

I think pfkey needs to also set the x->sel.family field when it is 0.

Tested with below patch, and ipsec worked when using pfkey.

3516ffb0fe [TCP]: Invoke tcp_sendmsg() directly, do not use inet_sendmsg().
As discovered by Evegniy Polyakov, if we try to sendmsg after
a connection reset, we can do incredibly stupid things.

The core issue is that inet_sendmsg() tries to autobind the
socket, but we should never do that for TCP.  Instead we should
just go straight into TCP's sendmsg() code which will do all
of the necessary state and pending socket error checks.

TCP's sendpage already directly vectors to tcp_sendpage(), so this
merely brings sendmsg() in line with that.
