bag in sctp_connectx

[Sergey Udalov]

Hi,

I am using sctp_darn with "--connectx" option and when I try to send  
any data then I get the error:
""sctp_darn: error connecting to addrs: Invalid argument.
   connectx failed."

Could you please analyze and fix the problem?

Version lksctp-tools: 1.0.16.
Version OS: 3.11-2-amd64 #1 SMP Debian 3.11.10-1 (2013-12-04) x86_64 
GNU/Linux.

Thank you in advanced.
Sergey Udalov

So you have a 3.11 64bit kernel. Do you have a 32bit user space, or, at least
lksctp-tools compilation?

If so, then you need the following commit that is for 3.14 and stable:
