Subject: [PATCH 1/2] e1000: fix memcpy in e1000_get_strings
Date: Wed, 05 Dec 2007 11:57:30 -0800 [thread overview]
Message-ID: <20071205195729.6859.97796.stgit@localhost.localdomain> (raw)
From: Roel Kluin <12o3l@tiscali.nl>
drivers/net/e1000/e1000_ethtool.c:113:
#define E1000_TEST_LEN sizeof(e1000_gstrings_test) / ETH_GSTRING_LEN
drivers/net/e1000e/ethtool.c:106:
#define E1000_TEST_LEN sizeof(e1000_gstrings_test) / ETH_GSTRING_LEN
E1000_TEST_LEN*ETH_GSTRING_LEN will expand to
sizeof(e1000_gstrings_test) / (ETH_GSTRING_LEN * ETH_GSTRING_LEN)
A lack of parentheses around defines causes unexpected results due to
operator precedences.
