The recent changes that added SMB3 encryption support introduced a possible use after free in the demultiplex thread. When we process an encrypted packed we obtain a pointer to SMB session but do not obtain a reference. This can possibly lead to a situation when this session was freed before we copy a decryption key from there. Fix this by obtaining a copy of the key rather than a pointer to the session under a spinlock. Signed-off-by: Pavel Shilovsky <pshilov@microsoft.com> Signed-off-by: Steve French <smfrench@gmail.com>
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.
