From 8467dda0c26583547731e7f3ea73fc3856bae3bf Mon Sep 17 00:00:00 2001 From: Petr Malat Date: Sat, 9 Apr 2022 08:36:11 +0200 Subject: sctp: Initialize daddr on peeled off socket Function sctp_do_peeloff() wrongly initializes daddr of the original socket instead of the peeled off socket, which makes getpeername() return zeroes instead of the primary address. Initialize the new socket instead.
