Re: how can I remove Adaptation Layer Indication parameter in INIT_ACK?

[malc]

Are you using a particularly old kernel? This was patched years ago to
only include ALI in INIT{_ACK} if the user has specified a valid (i.e.
non-zero) application code-point.

http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?idoc791ee631728b2beddda87560f1af59e32230e

Cheers,
malc.

Re: how can I remove Adaptation Layer Indication parameter in INIT_ACK?

[malc]

It's in the net/sctp subdirectory of the kernel source... the details
are right there in the link I gave you (on the diff ... line)

diff --git a/net/sctp/sm_make_chunk.c b/net/sctp/sm_make_chunk.c

Re: how can I remove Adaptation Layer Indication parameter in INIT_ACK?

[malc]

I'm sorry but support for the basics of obtaining and building the
linux kernel is well out of scope for this list. (and I have a day-job
to do ;-)
I politely suggest that you try and locate someone internally within
your organization to support you, contact the provider of your
distribution for support (if you're using a commercial one), or
failing that, google.

e.g. https://fedoraproject.org/wiki/Building_a_custom_kernel

The code change itself is simple - it adds a check to see if the user
provided an adaptation code point for the socket (if they didn't - the
value will be zero, which is IANA reserved) - and then /conditionally/
includes the ALI parameter only if one was explicitly specified.
More info on ALI can be found in the relevant RFC -
https://tools.ietf.org/html/rfc5061#section-4.2.6

Thanks,
malc.
