When a user requests scan, driver sends multiple scan requests to firmware, which might be active or passive. Firmware will send channel statistics for each channel in the request. This will be stored in chan_stats array. Few channels might report hidden SSIDs in passive scan results. So, once the original scan request is finished, driver issues an active scan request for all channels which reported hidden SSIDs. This will cause duplicates in the chan_stats array. At worst, every channel will have a hidden SSID, in which case the driver can issue active scan requests for each channel. So the complete scan statistics size will be twice of existing limit. At present maximum number of channels returned in scan statistics is 31(BG) + 14(A) = 45. Clearly there will be an overflow of the chan_stats array in the above mentioned scenario. To fix this double the size of chan_stats array.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
