Fork of reMarkable kernel https://github.com/reMarkable/linux

The parsing of sadb_x_ipsecrequest is broken in a number of ways. First of all we're not verifying sadb_x_ipsecrequest_len. This is needed when the structure carries addresses at the end. Worse we don't even look at the length when we parse those optional addresses. The migration code had similar parsing code that's better but it also has some deficiencies. The length is overcounted first of all as it includes the header itself. It also fails to check the length before dereferencing the sa_family field. This patch fixes those problems in parse_sockaddr_pair and then uses it in parse_ipsecrequest.

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.
