play the important typecast game

ssh mostly ignores the return value of select(), so if the timeout
expired it would assume that all input set descriptors had activity.

In case we get rv == 0 from the poll backend, zero out the fd

ssh mostly ignores the return value of select(), so if the timeout
expired it would assume that all input set descriptors had activity.

In case we get rv == 0 from the poll backend, zero out the fd sets
to signal that in fact no descriptors have activity.

Before this commit ssh was "jittery" when run through a rump tcp/ip
stack (interactive sessions kept blocking on stdin and you had to
"peddle" the connection). Now it works smoothly ... or at least
smoothly enough so that this commit could be done through a rump
tcp/ip stack:
USER COMMAND PID FD PROTO LOCAL ADDRESS FOREIGN ADDRESS
root ssh 125 0 tcp localhost.65517 cvs.netbsd.org.22

Fix pasto, use GETSYSCALLS() where possible

Make sure we can do host kevent since the -current (and recent nb5)
libc resolver uses it. Error out in case of rump fd kevent (TODO).
Fixes one more problem pointed out by Alexander Nasonov.

Also, implement dup().
(TODO: implement it along the fcntl path too)

add std dprint to fdcall

Force gcc to generate a stack frame for the call to dlsym(RTLD_NEXT).
Without this hack at least amd64 -O2 just used jmp and The Wrong
Thing happened.

duh, _sys_read, not read. STAY FIXED, DAMNIT!

Unbreak the ssp lossage from the default -current build by removing
it. I still don't have any idea what the ssp stuff is supposed to
do and how it's supposed to even begin to work. If someone wants
to change this now, run tests/lib/librumphijack before commit so
that I can avoid another multihour debugging session!

call the non-compat pollts() from inside the library

make it possible to specify client connection retry model in
RUMPHIJACK_RETRY

be kinder about kqueue()
(but paradoxically omit the surprise)

uncommit part of previous which wasn't supposed to change

Wrap daemon() since it forks. Otherwise we lose the rumpclient kq
descriptor and have multiple processes using the commfd.

Fix some snafus to allow rumphijack to work on -current.

Use NEEDED for librumpclient instead of loading it manually.

Set server reconnection timeout to infinite. There probably need
to be some toggle eventually, but for now I'm optimizing the default
for my firefox use ;)

make SSP friendly

fix compilation on -current

the usual fun for WARNS=4

signed,
unsigned

dramatic whitespace fix

Rewrite to declare most dual-kernel calls with macros. This helps
with adding new calls and makes all existing fd-accepting hijacked
calls dual-kernel. It would be better to autogenerate the code

Do the standard dance for sendto/recvfrom since nspluginwrapper
wants to use them. XXX: need to fold the dance sequence into a
common routine.

fix lp64 snafu (hopefully)

from pgoyette

* attempt to match libc non-compat names (XXX: needs work)
* make shutdown() a dual-stack call
* flip the default to use host for PF_UNIX, since that's generally
the desired case (because of X)

pollts:
Since fds[] does not go to both kernels, set revents to 0 when

This fixes a situation where a firefox transfer would occasionally
stall. Now firefox works full speed with a rump networking stack.
