This is unlikely to be the last of the path problems seen after
OTP 21, and I'm starting to regret my decision to unconditionally
use long paths. The idea to hit all long-path problems all the time
was good in theory as it makes such bugs far more visible, but
there just aren't enough people who test pre-release versions on
Windows, making this the world's slowest game of whack-a-mole.

This translates to TCP_CORK on Linux and TCP_NOPUSH on
BSD.
In effect, this acts as super-Nagle: no partial TCP segments
are sent out until this option is turned off. Once turned off,
all accumulated unsent data is sent out immediately. The latter
is *not* the case on OSX, hence the implementation ignores
"nopush" on OSX to reduce confusion.

Added a test case that specifically tested setting
the controlling_process.
Also, ensure that invalid updates of controlling-process
(not owner) actually fails.

The connect timeout test case uses the listen backlog argument
to test connect timeout (its set to 1). The idea is that when
the server backlog is full, it should not reply. The client attempting
to connect will then get a timeout.
But as it turns out, this behaviour is not "set in stone". On FreeBSD
11.2, the result is instead a 'econnreset'.
It should also be noted that this local connections. That is, both end
of the connection is on the same machine.
So, test case has been updated to also accept a econnreset (even
though that is not what it is testing).

This function is called when a logger API function for fetching
handler configuration is called. The point is to allow the handler to
remove internal data fields that it might have stored in the
configuration database, before returning the handler configuration to
the caller.
An example of such internal data are the 'handler_pid' and 'mode_tab'
fields that logger_std_h and logger_disk_log_h store in their
configuration maps.
|
|
The new parameter to this function, SetOrUpdate, indicates how
unspecified configuration data fields shall be set. The rule is that
if SetOrUpdate equals set, then default values shall be used, and if
SetOrUpdate equals update, then existing configuration values shall be
used. Consequently, these examples now apply to logger_std_h and
logger_disk_log_h:
set_handler_config(default, config, #{sync_mode_qlen => 20}) sets the
value of sync_mode_qlen to 20, and resets all other (writable) fields
in the config map to their default values.
update_handler_config(default, config, #{sync_mode_qlen => 20}) sets
the value of sync_mode_qlen to 20, and leaves all other fields in the
config map unchanged.

The macros for the BSD style option names had accidentally
wound up outside the option parsing loop, causing unclear
behaviour and Valgrind errors.
|

Add support for otp level socket options rcvbuf, rcvctrlbuf and
sndctrlbuf. These options define default sizes for these
buffers.
The 'rcvbuf' is used when receiving messages when calling
the recv, recvfrom and recvmsg functions.
The 'rcvctrlbuf' is used for the control message header info
when calling the recvmsg function.
The 'sndctrlbuf' is used for the control message header info
when calling the sendmsg function.

The test cases has been slighly regrouped. The to-group
has moved into the api-group.

Add a number of *basic* operation (connect, accept, send and recv).
All of which are not yet implemented (skipped with 'not-yet-implemented').
All of these are basic and only local (both sides on the same host).
OTP-14831
|
|
Added proper recv timeout handling.
Made use of the enif_select(mode = cancel) feature. Each
time a timeout expires, the "active" recv (the surrent reader
select) has to be cancelled. Not yet tested...something for
the new test suite...
Also, added support for getopt(controlling_pprocess) that,
for some reason, was not yet implemented.

Add a proper but very basic test suite.
The only (6) test cases now are very basic (open-close and
send-receive).
OTP-14831
|
|
Added proper send timeout handling.
Made use of the enif_select(mode = cancel) feature. Each
time a timeout expires, the "active" send (the surrent write
select) has to be cancelled.
OTP-14831
|
|
Added proper connect and accept timeout handling.
Made use of the enif_select(mode = cancel) feature. Each
time a timeout expires, the previous operation (connect or accept)
has to be cancelled (actually its the select operation that has
to be cancelled). Only partial implementation of cancel for now
(connect and accept). More to follow...

* raimo/receive-TOS-TCLASS/ERIERL-187/OTP-15145:
Elaborate the disclaimer for 'pktoptions'
Improve platform filter
Fix endianness bug for CMSG parsing
|
|
|
|
Added some more tests for sendmsg (with cmsghdr).
OTP-14831
|
|
Add more debug printouts for the new sendmsg. Also added
new (erlang) types with doc.
OTP-14831
|
|
Added function sendmsg/2,3,4. Actually worked on the first try.
Something must be wrong...
Still no supported cmsghdr's (only support headers where the
data part is already a binary, which therefor does not require
any processing). So if the cmsghdrs actually work is unclear.
OTP-14831
|
|
Added processing or more cmsg headers (for more options).
Now (also) supports: socket:timestamp.
Also various fixes and cleanups.
For some reason calling getopt(Sock, 0, {13, int}) (or similar)
fails with badarg even though the nif-function (nif_getopt) actually
returns a valid value (for instance: {ok, 0}).
OTP-14831
|
|
Added decoding of the "known" control message options: pktinfo,
recvtos, recvttl and recvorigdstaddr).
OTP-14831
|
|
It seems to work, with atleast some of the cmsg options.
More testing needed...
OTP-14831
|
|
Added support for ip level socket option SENDSRCADDR.
This option requires sendmsg to actually use, so we
cannot test this fully at the moment.
OTP-14831
|
|
Added support for ip level socket option RECVORIGDSTADDR.
This option requires recvmsg to actually use, so we cannot
test this fully at the moment (although both set and get works).

Added support for ip level socket option RETOPTS.
OTP-14831
|
|
Added support for ip level socket option TRANSPARENT.
OTP-14831
|
|
Added support for ip level socket option PKTINFO.
This option requires sendmsg and/or recvmsg to actually use,
so we cannot test this fully at the moment (although both set
and get works).
OTP-14831
|
|
Added support for the IPv6 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 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.
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 RTHDR and HOPLIMIT.
On FreeBSD, it says that HOPOPTS requires superuser privileges.
Needs furher checking.

|
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.
Needs furher checking.

|
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_IF.
