Tested now on the others

pooka e8083ecf03 Make sure holyfd is -1 when rumpclient_init() is called for 
the first time after fork to prevent fd 0 from being closed.

should fix test failures, thanks to martin for the prod

pooka e152ae2df5 fix build on NetBSD. also, prevent fd leak in error path 2014-04-02 15:04:19 +00:00
pooka 90c25cb369 On Linux, poll signalfd() when waiting for a kernel response. 
This allows the same type of race-free handling of signals as kqueue()
allows on NetBSD.  One of the noticeable things is that you can now
interrupt rumprun ping mid-interval on Linux.

per suggestion from Justin Cormack

pooka 94265f339d Use MAP_ANON|MAP_PRIVATE for anonymous memory mapping, 
e.g. Linux gets upset if just MAP_ANON.

pooka fa3922be63 Make librumpclient compile and work on Linux. This is accomplished by: 
1) avoid "NetBSD'isms" in the rumpclient sources
2) do not require the knowledge of unnecessary weird_t's in syscallargs.h

for vfork otherwise. Also give it the returns twice attribute to ensure

pooka 7905447e1d Since we ~never have a frame waiting on the initial call to waitresp, 
call kevent before readframe.  Doesn't really affect performance,
but makes ktraces shorter ;)

pooka 00e34b229c Use sendmsg() instead multiple calls to sendto(). It behaves 
slightly better in the multithreaded exec case in terms of partial
frames sent.  Plus, it's theoretically a little cheaper.

There's still a gray area with partial transfer from sendmsg(),
but I'm not sure I care enough about some academic scenario to
start fixing it (it basically needs an OOB exec signaller).

pooka ee6e286c6f Take reasonable precautions against init in a parent process 
which did a rump-transparent host-only fork().

pooka b8eb9b59e8 Make the rumphijack dlsym trampoline call from rumpclient a "real" 
function call instead of a call through a function pointer.
Apparently powerpc ld.elf_so gets __hackish_return_address() wrong
if the call is done through a function pointer (digging deeper into
that stuff is beyond my interest).

Thanks to riz for providing access to a macppc for debugging.
Unthanks to the broken toolchain in the default installation which
wasted approximately 4 hours of time last night.

breaks the build.

pooka 97c20c765b Disable string aliasing for rump_syscalls.c. I can't figure out 
how to otherwise make the kernel's register_t coreography to work
with the return value here in a MI fashion.
