[New-bugs-announce] [issue12809] Missing new setsockopts in Linux (eg: IP_TRANSPARENT)

[Michael Farrell]

New submission from Michael Farrell <micolous+py at gmail.com>:

Recently, iptables has added support for transparent proxies using a new TPROXY target on Linux2.  This requires a new option in setsockopts, IP_TRANSPARENT.  There's some background on the feature here:

http://www.mjmwired.net/kernel/Documentation/networking/tproxy.txt

I've created a patch to the header regen scripts on Linux2 that should expose this functionality to Python.  They'll need to be run to generate the headers again.

I notice that `_socket` doesn't include the names of socket options from this location, instead using a local database.  I had trouble trying to get `linux/in.h` included in that file, so I included a work-around which defines it statically for now.

It needs some work but it causes a lot of breakage when I try to do this -- and I don't know enough about the Linux sockets API to fix this properly.
