From 17bc55864f81dd730d05f09b1641312a7990d636 Mon Sep 17 00:00:00 2001 From: Peter Wu Date: Mon, 7 Dec 2015 01:07:31 +0100 Subject: [PATCH] rtlwifi: fix memory leak for USB device Free skb for received frames with a wrong checksum. This can happen pretty rapidly, exhausting all memory. This fixes a memleak (detected with kmemleak). Originally found while using monitor mode, but it also appears during managed mode (once the link is up).
