From 5dab10f444774dd119e3c370cd332df9c1c646c7 Mon Sep 17 00:00:00 2001 From: Joshua Clayton Date: Wed, 5 Aug 2015 17:17:14 -0700 Subject: [PATCH] staging: rtl8712: fix buggy size calculation r8712_get_ndis_wlan_bssid_ex_sz has a "6 * sizeof(unsigned long)" where the underlying struct has a 6 * unsigned char. Simplify the calculation by just subtracting the variable part from the size of the struct. This also gets rid of a use of typedef NDIS_802_11_RATES_EX Signed-off-by: Joshua Clayton Signed-off-by: Greg Kroah-Hartman --- drivers/staging/rtl8712/rtl871x_mlme.c | 12 +----------- 1 file changed, 1 insertion(+), 11 deletions(-) diff --git a/drivers/staging/rtl8712/rtl871x_mlme.c b/drivers/staging/rtl8712/rtl871x_mlme.c index c044b0e55ba9..6b3451f7017b 100644 --- a/drivers/staging/rtl8712/rtl871x_mlme.c +++ b/drivers/staging/rtl8712/rtl871x_mlme.c @@ -210,17 +210,7 @@ void r8712_generate_random_ibss(u8 *pibss) uint r8712_get_ndis_wlan_bssid_ex_sz(struct ndis_wlan_bssid_ex *bss) { - uint t_len; - - t_len = sizeof(u32) + 6 * sizeof(unsigned long) + 2 + - sizeof(struct ndis_802_11_ssid) + sizeof(u32) + - sizeof(s32) + - sizeof(enum NDIS_802_11_NETWORK_TYPE) + - sizeof(struct NDIS_802_11_CONFIGURATION) + - sizeof(enum NDIS_802_11_NETWORK_INFRASTRUCTURE) + - sizeof(NDIS_802_11_RATES_EX) + - sizeof(u32) + bss->IELength; - return t_len; + return sizeof(*bss) + bss->IELength - MAX_IE_SZ; } u8 *r8712_get_capability_from_ie(u8 *ie) -- 2.39.5
