Someone please look into this.
In prism2_ioctl_scan_req() gcc generates a warning:
drivers/net/wireless/prism54/isl_ioctl.c: In function ʽprism2_ioctl_scan_reqʼ:
drivers/net/wireless/prism54/isl_ioctl.c:2733:14: warning: array subscript is above array bounds [-Warray-bounds]
it's a pretty serious issue, it's about the call to:
current_ev = prism54_translate_bss(ndev, &info, current_ev,
extra + IW_SCAN_MAX_DATA,
&(bsslist->bsslist[i]),
noise);
it's not the bsslist->bsslist[i] thing, that's fine.
It's "extra + IW_SCAN_MAX_DATA".
char *extra = "";
char *current_ev = "foo";
and IW_SCAN_MAX_DATA is 4096. Effectively these calls crap IW entries
into random pieces of memory as far as I can tell.
We either need to figure out where this ioctl interface expects the
response to go, or remove the ioctl and this code entirely since it's
obviously not being used.
Thanks.
