minstrel_ht
Hello Thomas Huehn,
The patch 0a08adeb773c: "mac80211: correct size the argument to
kzalloc in minstrel_ht" from Jun 29, 2012, leads to the following
Sparse warning:
net/mac80211/rc80211_minstrel_ht.c:816:33:
warning: expression using sizeof(void)
- msp->ratelist = kzalloc(sizeof(struct minstrel_rate) * max_rates, gfp);
+ msp->ratelist = kzalloc(sizeof(*msp->ratelist) * max_rates, gfp);
if (!msp->ratelist)
goto error;
"msp->ratelist" is a void pointer so that will cause memory corruption.
You could consider making it a struct minstrel_rate pointer. I haven't
looked at this.
regards,
dan carpenter
