hiya,
this popped up from the freebsd.org coverity scan:
________________________________________________________________________________________________________
*** CID 1343338: Memory - illegal accesses (OVERRUN)
/sys/dev/usb/wlan/if_urtwn.c: 4288 in urtwn_r88e_newassoc()
4282
4283 if (!isnew)
4284 return;
4285
4286 URTWN_NT_LOCK(sc);
4287 for (id = 0; id <= URTWN_MACID_MAX(sc); id++) {
CID 1343338: Memory - illegal accesses (OVERRUN)
Overrunning array "sc->node_list" of 63 8-byte elements at
element index 63 (byte offset 504) using index "id" (which evaluates
to 63).
4288 if (id != URTWN_MACID_BC && sc->node_list[id] ==
NULL) {
4289 un->id = id;
4290 sc->node_list[id] = ni;
4291 break;
4292 }
4293 }
Would one of you figure it out?
Thanks!
-a
#define R88E_MACID_MAX 63
...
struct ieee80211_node *node_list[R88E_MACID_MAX];
of course, I mean here 64, not 63 (probably, it was a bad idea to replace
first inaccessible element with last accessible).
