From 90a56f72edb088c678083c32d05936c7c8d9a948 Mon Sep 17 00:00:00 2001 From: Luiz Augusto von Dentz Date: Fri, 12 Aug 2016 15:11:28 +0300 Subject: Bluetooth: Fix bt_sock_recvmsg when MSG_TRUNC is not set Commit b5f34f9420b50c9b5876b9a2b68e96be6d629054 attempt to introduce proper handling for MSG_TRUNC but recv and variants should still work as read if no flag is passed, but because the code may set MSG_TRUNC to msg->msg_flags that shall not be used as it may cause it to be behave as if MSG_TRUNC is always, so instead of using it this changes the code to use the flags parameter which shall contain the original flags.
