now automatically picked based on the ABI of the target the library
is compiled for.
(the host libc symbolname to override still needs a little attention
based on the system version)
contact the X server. Since most of the useful cases these days
are local, add a toggle which forwards PF_LOCAL sockets to the host
and all other protocol families to the rump kernel.
This makes an unmodified firefox work with a rump TCP/IP stack.
I'm sure someone will find applications for being able to run
multiple web browser profiles on one OS with each browser having
a different IP address in the same subnet ...
would have been much easier if up to and including 5.0 we wouldn't
silently cap the nfds argument to poll(!!!).
Makes things like socket(1) work out-of-the-box, and pretty much
every other decidedly prehistoric select() user.
(netcat is a slight exception since it sets FD_SETSIZE, a.k.a.
interface-of-the-year, to 16)
to convince non-rumped applications to communicate with a rump
kernel instead of the host kernel. The precision of what goes
where is not exactly surgical, but for example when wanting to
debug a web server's TCP/IP stack interaction, it might be enough.
When all you have is a hand grenade, all problems look like a ....
hmm?
There's still plenty to figure out. For example, I'm not sure what
the user interface will be like. Now it just attempts to hijack
network communication. It also needs to sync with symbol renaming
in libc, and maybe autogenerate the non-schizophrenic wrappers
where the communication is heading to exactly one destination, lest
I'll be a mummmy by the time I finish writing them all. As a fun
example of a non-non-schizophrenic one, consider poll().
Work in progress, but I managed to get two non-rumped netcats
talking to each other or fetching the index from a non-rumped
thttpd. telnet works in one direction (i can read the data from
netcat, but anything i send back is not printed). bozohttpd uses
dup2() which i haven't bothered to address yet, etcetc.
(not hooking this up the build for now)
