Regression found when running LTP connect01 on next-20180301

Hi,

I was running LTP's testcase connect01 [1] and found a regression in linux-next
(next-20180301).  Bisect gave me this patch as the problematic patch (sha
d452930fd3b9 "selinux: Add SCTP support") on a x86 target.

Output from the test(LTP release 20180118):
$ cd /opt/ltp/
$ cat runtest/syscalls |grep connect01>runtest/connect-syscall
$ ./runltp -pq -f connect-syscall
"
Running tests.......
connect01    1  TPASS  :  bad file descriptor successful
connect01    2  TPASS  :  invalid socket buffer successful
connect01    3  TPASS  :  invalid salen successful
connect01    4  TPASS  :  invalid socket successful
connect01    5  TPASS  :  already connected successful
connect01    6  TPASS  :  connection refused successful
connect01    7  TFAIL  :  connect01.c:146: invalid address family ; returned -1 (expected -1), errno 22 (expected 97)
INFO: ltp-pan reported some tests FAIL
LTP Version: 20180118
"

The output from the test expected 97 and we received 22, can you please
elaborate on what have been changed?


Cheers,
Anders
