lib: Add msghdr_prep_recv_fds

2015-01-05T23:33:10+00:00

This will prepare a msghdr for receiving fd's. Same pattern as before: First
get the buffer size, then fill in msghdr.

lib: Add msghdr_extract_fds

2015-01-05T23:33:09+00:00

This is a copy of the extract_fd_array_from_msghdr routine in unix_msg.c, with
a similar use pattern: First call it without an output array to get the length
and then call it a second time to actually fill in the array.

lib: Add msghdr.[ch]

2015-01-05T23:33:09+00:00

This is a little set of routines to deal with the ugly fd-passing macros.

This patch is the first step assisting the creation of msghrds for sending fds.
Receiving fd helpers will follow later.

The basic idea behind these routines is that they fill a variable-sized buffer.
They are supposed to be called twice per msghdr preparation. First with a
0-sized NULL output buffer to calculate the required bufsize, and then a second
time filling in the buffer as such.

This does not take care of the old msg_accrights way of passing file
descriptors. CMSG/SCM_RIGHTS is standardized for quite a while now, and I
believe this intreface can be made to also take care of msg_accrights if
needed.
