Running SOCK_SEQPACK SCTP tests and performance tests

[em-cph]

Hi,

I'm trying to run SOCK_SEQPACK_SCTP_Test and can't figure out why it's failing.
I'm wondering if there's anything required for SCTP tests to run except adding #define ACE_HAS_SCTP in config.h

The machine i'm using runs on RHEL7.9
I tried with ACE 7.0.6 and ACE 6.5.5 and had the same results.

my config.h

#include "ace/config-linux.h"
#define ACE_HAS_SCTP

Here's a the output I get when running the auto test

[eddy@cph1-dev tests]$ perl run_test.pl 
auto_run_tests: tests/SOCK_SEQPACK_SCTP_Test 

auto_run_tests_finished: tests/SOCK_SEQPACK_SCTP_Test  Time:12s Result:0

I also tried running the performance tests by running SOCK_SEQPACK_srv

[eddy@cph1-dev SCTP]$ ./SOCK_SEQPACK_srv 
(31432|140676311308096) Accepting connections, using IPPROTO_SCTP on port 45453 on interfaces 0.0.0.0
(31432|140676311308096) select timed out

And SOCK_SEQPACK_Association_Test to connect to the server but I end up getting Transport endpoint is not connected

[eddy@cph1-dev SCTP]$ ./SOCK_SEQPACK_Association_Test 127.0.0.1:45453
Connected to server at 127.0.0.1:45453
Called get_local_addrs
get_local_addrs[0] = 127.0.0.1:41328
get_remote_addrs: Transport endpoint is not connected

Could anyone tell if i'm doing anything wrong?

A little update on this topic, I was able to run SCTP tests on FreeBSD 12.1 without any issues.
Seems like RHEL 7+ have some kernel issues related to SCTP.

Will update the discussion once I have a better understanding on the topic.
