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. Fixes: d570ee490fb1 ("[SCTP]: Correctly set daddr for IPv6 sockets during peeloff") Signed-off-by: Petr Malat <oss@malat.biz> Acked-by: Marcelo Ricardo Leitner <marcelo.leitner@gmail.com> Link: https://lore.kernel.org/r/20220409063611.673193-1-oss@malat.biz Signed-off-by: Jakub Kicinski <kuba@kernel.org>
