drain timeout handling to historical freebsd behavior.
The primary reason for these changes is the need to have tty_drain() call
ttydevsw_busy() at some reasonable sub-second rate, to poll hardware that
doesn't signal an interrupt when the transmit shift register becomes empty
(which includes virtually all USB serial hardware). Such hardware hangs
in a ttyout wait, because it never gets an opportunity to trigger a wakeup
from the sleep in tty_drain() by calling ttydisc_getc() again, after
handing the last of the buffered data to the hardware.
While researching the history of changes to tty_drain() I stumbled across
some email describing the historical BSD behavior of tcdrain() and close()
on serial ports, and the ability of comcontrol(1) to control timeout
behavior. Using that and some advice from Bruce Evans as a guide, I've
put together these changes to implement the hardware polling and restore
the historical timeout behaviors...
- tty_drain() now calls ttydevsw_busy() in a loop at 10 Hz to accomodate
hardware that requires polling for busy state.
- The "new historical" behavior for draining during close(2) is retained:
the drain timeout is "1 second without making any progress". When the
1-second timeout expires, if the count of bytes remaining in the tty
layer buffer is smaller than last time, the timeout is extended for
another second. Unfortunately, the same logic cannot be extended all
the way down to the hardware, because the interface to that layer is a
simple busy/not-busy indication.
- Due to the previous point, an application that needs a guarantee that
all data has been transmitted must use TIOCDRAIN/tcdrain(3) before
calling close(2).
- The historical behavior of honoring the drainwait setting for TIOCDRAIN
(used by tcdrain(3)) is restored.
- The historical kern.drainwait sysctl to control the global default
drainwait time is restored, but is now named kern.tty_drainwait.
- The historical default drainwait timeout of 300 seconds is restored.
- Handling of TIOCGDRAINWAIT and TIOCSDRAINWAIT ioctls is restored
(this also makes the comcontrol(1) drainwait verb work again).
- Manpages are updated to document these behaviors.

Include netinet/in.h before ip_compat.t which will then check if
IPPROTO_IPIP is defined or not. Doing it the other way round,
ip_compat.h would not find it defined and netinet/in.h then
redefine it.
Active Open:
- Save the socket's vnet at the time of the active open (t4_connect) and
switch to it when processing the reply (do_act_open_rpl or
do_act_establish).
Passive Open:
- Save the listening socket's vnet in the driver's listen_ctx and switch
to it when processing incoming SYNs for the socket.
- Reject SYNs that arrive on an ifnet that's not in the same vnet as the
listening socket.
CLIP (Compressed Local IPv6) table:
- Add only those IPv6 addresses to the CLIP that are in a vnet
associated with one of the card's ifnets.
Misc:
- Set vnet from the toepcb when processing TCP state transitions.
- The kernel sets the vnet when calling the driver's output routine
so t4_push_frames runs in proper vnet context already. One exception
is when incoming credits trigger tx within the driver's ithread. Set
the vnet explicitly in do_fw4_ack for that case.

Probably for good, FORTIFY_SOURCE and this particular GCCism were never
well supported by clang or other compilers. Furthermore, the technology
has long since been replaced by either static checkers, sanitizers, or
even just the strong stack protector that was enabled by default.
