Xin Long says: ==================== security: fixups for the security hooks in sctp There are a couple of problems in the currect security hooks in sctp: 1. The hooks incorrectly treat sctp_endpoint in SCTP as request_sock in TCP, while it's in fact no more than an extension of the sock, and represents the local host. It is created when sock is created, not when a conn request comes. sctp_association is actually the correct one to represent the connection, and created when a conn request arrives. 2. security_sctp_assoc_request() hook should also be called in processing COOKIE ECHO, as that's the place where the real assoc is created and used in the future. The problems above may cause accept sk, peeloff sk or client sk having the incorrect security labels. So this patchset is to change some hooks and pass asoc into them and save these secids into asoc, as well as add the missing sctp_assoc_request hook into the COOKIE ECHO processing. v1->v2: - See each patch, and thanks the help from Ondrej, Paul and Richard. ==================== Signed-off-by: David S.

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.
