Eric Biggers d5a253702a sctp: Stop accepting md5 and sha1 for net.sctp.cookie_hmac_alg
The upgrade of the cookie authentication algorithm to HMAC-SHA256 kept
some backwards compatibility for the net.sctp.cookie_hmac_alg sysctl by
still accepting the values 'md5' and 'sha1'.  Those algorithms are no
longer actually used, but rather those values were just treated as
requests to enable cookie authentication.

As requested at
https://lore.kernel.org/netdev/CADvbK_fmCRARc8VznH8cQa-QKaCOQZ6yFbF=1-VDK=zRqv_cXw@mail.gmail.com/
and https://lore.kernel.org/netdev/20250818084345.708ac796@kernel.org/ ,
go further and start rejecting 'md5' and 'sha1' completely.

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 reStructuredText 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.
