Hello,
Is anyone actually interested in the files:
drivers/staging/rtl8192e/rtllib_softmac.c
drivers/staging/rtl8192u/ieee80211/ieee80211_softmac.c
Both contain the following code:
if (param->u.wpa_ie.len > MAX_WPA_IE_LEN ||
(param->u.wpa_ie.len && param->u.wpa_ie.data == NULL))
return -EINVAL;
and
if (param->u.crypt.alg != NULL) {
memcpy(sec.keys[param->u.crypt.idx],
param->u.crypt.key,
param->u.crypt.key_len);
In each case, the NULL test has a trivial result, because the requested
field is an array inlined within a structure. In the first case, the
array has size 0, so I guess the intent is to see whether some more space
has been allocated, and in the second case the array contains a string, so
I guess the intent is to see whether something has been stored in the
string. But I don't know how it is intended to do either operation.
