Description Vit Mojzis 2019-10-23 10:53:19 UTC 
Description of problem:
sctp_test fails to process "-h localhost" (*** sendmsg: Invalid argument ***)

After replacing "localhost", with "127.0.0.1" or "::1", the command works properly.

This issue is not present in the latest upstream release (lksctp-tools-1.0.18). 

Version-Release number of selected component (if applicable):
lksctp-tools-1.0.16-12.fc31.x86_64


Steps to Reproduce:
# sctp_test -H localhost -P 1026 -l &
# sctp_test -H localhost -P 1052 -h localhost -p 1026 -s

Actual results:
seed = 1571827214

Starting tests...
	socket(SOCK_SEQPACKET, IPPROTO_SCTP)  ->  sk=4
	bind(sk=4, [a:::,p:cap])  --  attempt 1/10
	listen(sk=4,backlog=100)
Server: Receiving packets.
	recvmsg(sk=4) sctp_test -H localhost -P 1052 -h localhost -p 1026 -s
remote:addr=::, port=cap, family=10
local:addr=::, port=ddt, family=10
seed = 1571827222

Starting tests...
	socket(SOCK_SEQPACKET, IPPROTO_SCTP)  ->  sk=4
	bind(sk=4, [a:::,p:ddt])  --  attempt 1/10
Client: Sending packets.(1/10)
	sendmsg(sk=4, assoc=0)    1 bytes.
	  SNDRCV(stream=0 flags=0x1 ppid=915480447

		*** sendmsg: Invalid argument ***


Expected results:
...
	recvmsg(sk=4) Data 1 bytes. First 1 bytes: <empty> text[0]=0
	  SNDRCV(stream=0 ssn=0 tsn=3832062224 flags=0x1 ppid=36046225
cumtsn=3832062224
	recvmsg(sk=4) Data 1 bytes. First 1 bytes: <empty> text[0]=0
	  SNDRCV(stream=0 ssn=0 tsn=3832062225 flags=0x1 ppid=1460416525
cumtsn=3832062225
	recvmsg(sk=4) Notification: SCTP_ASSOC_CHANGE(SHUTDOWN_COMPLETE)
...
