From 8e5d9433412d34f02a83edd265605bfe6c347a0a Mon Sep 17 00:00:00 2001 From: Aya Mahfouz Date: Wed, 4 Mar 2015 08:56:45 +0200 Subject: [PATCH] staging: rtl8188eu: replace memset(x,0,ETH_ALEN) eth_zero_addr() is a wrapper function for memset if 0 is going to be assigned to a mac address. The aforementioned function replaces memset. In addition, linux/etherdevice.h was included as a header since it is the file that define the inline function eth_zero_addr(). The changes were carried out using the following coccinelle script: @header@ @@ #include @eth_zero_addr@ expression e; @@ -memset(e,0,ETH_ALEN); +eth_zero_addr(e); @eth_broadcast_addr@ identifier e; @@ -memset(e,\(0xff\|0xFF\|255\),ETH_ALEN); +eth_broadcast_addr(e); @linux_header depends on !header && (eth_zero_addr || eth_broadcast_addr) @ @@ + #include + @special_header depends on !header && !linux_header && (eth_zero_addr || eth_broadcast_addr) @ @@ + + #include + @custom_header depends on !header && !linux_header && !special_header && (eth_zero_addr || eth_broadcast_addr) @ @@ + + #include Signed-off-by: Aya Mahfouz Signed-off-by: Greg Kroah-Hartman --- drivers/staging/rtl8188eu/os_dep/ioctl_linux.c | 10 ++++++---- 1 file changed, 6 insertions(+), 4 deletions(-) diff --git a/drivers/staging/rtl8188eu/os_dep/ioctl_linux.c b/drivers/staging/rtl8188eu/os_dep/ioctl_linux.c index 58998f2f2b09..96c1c2d4a112 100644 --- a/drivers/staging/rtl8188eu/os_dep/ioctl_linux.c +++ b/drivers/staging/rtl8188eu/os_dep/ioctl_linux.c @@ -32,6 +32,8 @@ #include #include +#include + #include "osdep_intf.h" #define RTL_IOCTL_WPA_SUPPLICANT (SIOCIWFIRSTPRIV + 30) @@ -92,7 +94,7 @@ void rtw_indicate_wx_disassoc_event(struct adapter *padapter) memset(&wrqu, 0, sizeof(union iwreq_data)); wrqu.ap_addr.sa_family = ARPHRD_ETHER; - memset(wrqu.ap_addr.sa_data, 0, ETH_ALEN); + eth_zero_addr(wrqu.ap_addr.sa_data); DBG_88E_LEVEL(_drv_always_, "indicate disassoc\n"); wireless_send_event(padapter->pnetdev, SIOCGIWAP, &wrqu, NULL); @@ -827,7 +829,7 @@ static int rtw_wx_set_pmkid(struct net_device *dev, for (j = 0; j < NUM_PMKID_CACHE; j++) { if (!memcmp(psecuritypriv->PMKIDList[j].Bssid, strIssueBssid, ETH_ALEN)) { /* BSSID is matched, the same AP => Remove this PMKID information and reset it. */ - memset(psecuritypriv->PMKIDList[j].Bssid, 0x00, ETH_ALEN); + eth_zero_addr(psecuritypriv->PMKIDList[j].Bssid); psecuritypriv->PMKIDList[j].bUsed = false; break; } @@ -1028,7 +1030,7 @@ static int rtw_wx_get_wap(struct net_device *dev, wrqu->ap_addr.sa_family = ARPHRD_ETHER; - memset(wrqu->ap_addr.sa_data, 0, ETH_ALEN); + eth_zero_addr(wrqu->ap_addr.sa_data); RT_TRACE(_module_rtl871x_mlme_c_, _drv_info_, ("rtw_wx_get_wap\n")); @@ -1037,7 +1039,7 @@ static int rtw_wx_get_wap(struct net_device *dev, ((check_fwstate(pmlmepriv, WIFI_AP_STATE)) == true)) memcpy(wrqu->ap_addr.sa_data, pcur_bss->MacAddress, ETH_ALEN); else - memset(wrqu->ap_addr.sa_data, 0, ETH_ALEN); + eth_zero_addr(wrqu->ap_addr.sa_data); return 0; } -- 2.30.2
