Merge tag 'rxrpc-next-20201123' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
David Howells says:
====================
rxrpc: Prelude to gssapi support
Here are some patches that do some reorganisation of the security class
handling in rxrpc to allow implementation of the RxGK security class that
will allow AF_RXRPC to use GSSAPI-negotiated tokens and better crypto. The
RxGK security class is not included in this patchset.
It does the following things:
(1) Add a keyrings patch to provide the original key description, as
provided to add_key(), to the payload preparser so that it can
interpret the content on that basis. Unfortunately, the rxrpc_s key
type wasn't written to interpret its payload as anything other than a
string of bytes comprising a key, but for RxGK, more information is
required as multiple Kerberos enctypes are supported.
(2) Remove the rxk5 security class key parsing. The rxk5 class never got
rolled out in OpenAFS and got replaced with rxgk.
(3) Support the creation of rxrpc keys with multiple tokens of different
types. If some types are not supported, the ENOPKG error is
suppressed if at least one other token's type is supported.
(4) Punt the handling of server keys (rxrpc_s type) to the appropriate
security class.
(5) Organise the security bits in the rxrpc_connection struct into a
union to make it easier to override for other classes.
(6) Move some bits from core code into rxkad that won't be appropriate to
rxgk.
* tag 'rxrpc-next-20201123' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs:
rxrpc: Ask the security class how much space to allow in a packet
rxrpc: rxkad: Don't use pskb_pull() to advance through the response packet
rxrpc: Organise connection security to use a union
rxrpc: Don't reserve security header in Tx DATA skbuff
rxrpc: Merge prime_packet_security into init_connection_security
rxrpc: Fix example key name in a comment
rxrpc: Ignore unknown tokens in key payload unless no known tokens
rxrpc: Make the parsing of xdr payloads more coherent
rxrpc: Allow security classes to give more info on server keys
rxrpc: Don't leak the service-side session key to userspace
rxrpc: Hand server key parsing off to the security class
rxrpc: Split the server key type (rxrpc_s) into its own file
rxrpc: Don't retain the server key in the connection
rxrpc: Support keys with multiple authentication tokens
rxrpc: List the held token types in the key description in /proc/keys
rxrpc: Remove the rxk5 security class as it's now defunct
keys: Provide the original description to the key preparser

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.
