Added support for the IP socket option RECVERR.
To actually make use of this option, we need the recvmsg
function, which we don't have yet. Baby steps.

Added support for the IPv6 socket option ROUTER_ALERT.
Only supported for raw sockets.

Added support for the IPv6 socket option UNICAST_HOPS.

Added support for the IPv6 socket option(s) FLOWINFO.
The option returns with einval when calling setsockopt,
so either you need to be a privileged user to update, or its not
actually possible to update this option (even though it says
nothing about that in the man page. It only talks about set).
This is the same behaviour as with DSTOPTS.
Needs furher checking.

Added support for the IPv6 socket option(s) DSTOPTS.

actually possible to update this option (even though it says
nothing about that in the man page. It only talks about set).
This is the same behaviour as with RTHDR and HOPLIMIT.
On FreeBSD, it says that HOPOPTS requires superuser privileges.

Added support for the IPv6 socket option(s) AUTHHDR and HOPOPTS.
Its possible that the option is AUTHHDR is obsolete. It says so in
the include files and when trying to get it (getsockopt) it returns
with enoprotoopt.
The option HOPOPTS returns with einval when calling setsockopt,
so either you need to be a privileged user to update, or its not
actually possible to update this option (even though it says
nothing about that in the man page. It only talks about set).
This is the same behaviour as with RTHDR and HOPLIMIT.
On FreeBSD, it says that HOPOPTS requires superuser privileges.

Added support for the IPv6 socket option RTHDR.
On FreeBSD this option requires superuser privileges to update.
There is no mention of this on linux, but its still not possible
to update (einval), so I assume that its the same there.

Added support for the IPv6 socket option RECVPKTINFO.
This option is called PKTINFO on FreeBSD, so that value
will also be accepted.

Added support for the IPv6 socket option MULTICAST_LOOP.

Added support for ip level socket option RECVOPTS.

Added support for ip level socket option FREEBIND.
Note that there is an option available on FreeBSD called
IP_BINDANY, which seems to have similar properties (FREEBIND
is *not* available on FreeBSD). There are some restrictions
for this option though (which is not mentioned in the Linux
man page).

Added support for socket level socket option TIMESTAMP.

Added support for socket level socket option RCVLOWAT and SNDLOWAT.
These are both a little strange, at least on Linux. See the man
pages for more info. For instance, sndlowat cannot be set on Linux.

Added support for socket level socket option RCVTIMEO and SNDTIMEO.
These are both a little strange, at least on linux. See the man

Added support for the SCTP option RTOINFO.
We have the same questions for this option as for ASSOCINFO.
Maybe the assoc field shall be made 'out' only (that is, it will
be ignored for setopt). The assoc id used will be that which
is stored in the descriptor (how do we get it to begin with?).
Questions, questions...

Added support for the SCTP option ASSOCINFO.
This option is a bit tricky. As the underlying structure (sctp_assocparams)
contains the assoc_id, it begs the question what happens if this option
is fetched for:
* The own assoc (which means that we might have the assoc id in the
descriptor and can initiate that part of the struct accordningly).
* Another assoc: From assoc A asks for info with assoc_id set to
that of assoc B.
* The "owning" endpoint.
* Another endpoint (an endpoint to which the assoc does not belong).
So, if the user calls socket:[getopt|setopt] for an association socket,
shall we require that the assoc_id field is set to -1? Or not set at all
and therefor filled in automatically by the nif-code?
And, if the user calls socket:[getopt|setopt] for an endpoint socket,
shall we require that the assoc_id field is set to a valid id? Or shall
it not be allowed?

The socket option (level socket) debug is now supported.
To actually set this option, the user must have the proper
"authority" (CAP_NET_ADMIN capability or an effective user ID of 0).

Fixed handling of recvfrom (used by dgram sockets).
Had forgot to do select(read) when we got block from
the call to recvfrom. Argh!
Also updated the (simple) test server and client to to
be able to use udp (dgram+udp).
OTP-14831

|
|
Fixed handling of closed in the recv function.
We still need to properly handle when we get
0 bytes of data for other types ock sockets
then stream (its valid for dgram for instance).

Added some more features o the simple socket test server
