From f6fc6bc0b8e0bb13a210bd7386ffdcb1a5f30ef1 Mon Sep 17 00:00:00 2001 From: Xin Long Date: Sat, 28 Oct 2017 19:43:56 +0800 Subject: sctp: fix a type cast warnings that causes a_rwnd gets the wrong value These warnings were found by running 'make C=2 M=net/sctp/'. Commit d4d6fb5787a6 ("sctp: Try not to change a_rwnd when faking a SACK from SHUTDOWN.") expected to use the peers old rwnd and add our flight size to the a_rwnd. But with the wrong Endian, it may not work as well as expected. So fix it by converting to the right value. Fixes: d4d6fb5787a6 ("sctp: Try not to change a_rwnd when faking a SACK from SHUTDOWN.")
