Routine rtw_get_sec_ie() appears to suffer from a bug triggered under unusual circumstances. This bug is exposed by first sending a deauthentication frame and at the same time sending a much larger frame. After doing some debugging the cause of the lockup of the CPU was that while rtw_get_sec_ie() attempts to read the beacon frame sent by the router/AP, the size of the beacon is changed since it is a reference and not a copy. By having a "rogue" beacon frame being very large which isn't normal and not considered in the design, the computer was stuck in an endless CPU lockup. Routine translate_scan(), which calls rtw_get_sec_ie() is protected by a spinlock. Add that spinlock around other calls of the routine. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net>
