Add checks in ipa_table_init() to ensure the memory regions defined for IPA filter and routing tables are valid. For routing tables, the checks ensure: - The non-hashed IPv4 and IPv6 routing tables are defined - The non-hashed IPv4 and IPv6 routing tables are the same size - The number entries in the non-hashed IPv4 routing table is enough to hold the number entries available to the modem, plus at least one usable by the AP. For filter tables, the checks ensure: - The non-hashed IPv4 and IPv6 filter tables are defined - The non-hashed IPv4 and IPv6 filter tables are the same size - The number entries in the non-hashed IPv4 filter table is enough to hold the endpoint bitmap, plus an entry for each defined endpoint that supports filtering. In addition, for both routing and filter tables: - If hashing isn't supported (IPA v4.2), hashed tables are zero size - If hashing *is* supported, all hashed tables are the same size as their non-hashed counterparts. When validating the size of routing tables, require the AP to have at least one entry (in addition to those used by the modem).

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. 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.
