From d71be937202853eda76562e9678073465d5c0fa8 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Fri, 23 Dec 2011 08:13:42 +0100 Subject: iwlegacy: off by one in iwl3945_hw_build_tx_cmd_rate() We use "rate_index" like this: rate = iwl3945_rates[rate_index].plcp; The iwl3945_rates[] array has IWL_RATE_COUNT_3945 elements so the limit here is off by one.
