DO NOT REPLY [Bug 48918] New: Add support for SCTP beyond opening an
SCTP socket.
https://issues.apache.org/bugzilla/show_bug.cgi?id=48918
Summary: Add support for SCTP beyond opening an SCTP socket.
Product: APR
Version: 1.3.9
Platform: All
OS/Version: All
Status: NEW
Severity: enhancement
Priority: P2
Component: APR
AssignedTo: bugs@apr.apache.org
ReportedBy: leighton@cis.udel.edu
APR has supported using SCTP socket for many years, but it does not support
access to the many features of SCTP. I am proposing to add support for
sctp_sendmsg() and sctp_recvmsg(), as well as methods to get and set the many
SCTP socket options that are not simply on/off options.

Hello,
Wondering if our patch worked on Linux and other platforms. We'd really
appreciate any feedback/comments on the patch. Thanks!

I've updated the patch and would very much appreciate any feedback. The patch
has been tested on recent versions of FreeBSD, Linux, Mac OS X, Solaris,
Solaris Express, and Windows XP. I'm now working on updating this from 1.4.5
to trunk and will then add support for more recent versions of Windows.
The patch is broken into three files:
apr-1.4.5_sctp_main.patch - adds support for non-Windows platforms
apr-1.4.5_sctp_win32.patch - adds support for Windows XP (requires main)
apr_1.4.5_sctp_test.patch - adds support for tests on all platforms (requires
main and win32)
Support for SCTP on Mac OS X requires installing the SCTP network kernel
extension from http://sctp.fh-muenster.de/sctp-nke.html
Support for SCTP on Windows requires installing the SCTP driver and library
from http://www.bluestop.org/SctpDrv
All other platforms have native support for SCTP.

Support for additional SCTP functionality
I've attached a patch that adds the following new functions:
apr_socket_sctp_sendmsg()
apr_socket_sctp_recvmsg()
apr_socket_opt_set_sctp()
apr_socket_opt_get_sctp()
The patch also adds support for the SCTP on/off socket option
SCTP_USE_EXT_RCVINFO, and adds SCTP socket test code to several files in the
test directory, as well as adding an additional file called testsockopt_sctp.c.

Extending support beyond just Mac OS X and FreeBSD might increase interest.
According to Wikipedia, Linux, AIX, HP-UX, and Solaris all support SCTP, and
others; any reason not to include them?

The bigger picture with this effort is to add SCTP streams support into
Apache's APR and httpd server.
The current HTTP over SCTP design
(http://tools.ietf.org/html/draft-natarajan-http-over-sctp-01) exploits SCTP
streams to avoid head-of-line blocking. SCTP (RFC 4960) also offers other
services unavailable in TCP such as unordered delivery, partially reliable
transmission, message based transfer, multihoming support, more
secure connection establishment with a cookie mechanism and so on.
Our empirical study has shown that HTTP over SCTP streams improves HTTP
response times, and created a lot of interest at IETF's http-bis WG.
Jon Leighton (who submitted this patch) has been working with mozilla to get
HTTP/SCTP into Firefox and NSPR's source repositories
(https://bugzilla.mozilla.org/show_bug.cgi?id=486199). Our hope is to do
something similar with APR and httpd.
We'd appreciate any comments/suggestions on the patch. Thanks!

The patch should support FreeBSD, Mac OS X, Linux, Solaris and Open Solaris,
though I haven't yet tested it on either Solaris or OpenSolaris. If you have
trouble getting the patch to work on any of those systems I would like to know
about it. AIX and HP-UX are more of a problem because they are proprietary and
not widely available (in the same way and Mac OS X and Windows are). I would
be very interested in hearing from anyone that has access to either AIX or
HP-UX and is willing to test out the patch. I'm guessing you concluded that
the patch only supported FreeBSD and Mac OS X because my modifications to
configure.in explicity check for those two OSes. The OS check is there because
only the FreeBSD and Mac OS X implementations of SCTP currently support the
SCTP_USE_SCTP_RCVINFO socket option.
