Linux kernel source tree
86fdb3448c
Now before dumping a sock in sctp_diag, it only holds the sock while the ep may be already destroyed. It can cause a use-after-free panic when accessing ep->asocs. This patch is to set sctp_sk(sk)->ep NULL in sctp_endpoint_destroy, and check if this ep is already destroyed before dumping this ep.

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.
