This is an internal rework of the pkey code to not use the struct pkey_protkey internal any more. This struct has a hard coded protected key buffer with MAXPROTKEYSIZE = 64 bytes. However, with support for ECC protected key, this limit is too short and thus this patch reworks all the internal code to use the triple u8 *protkey, u32 protkeylen, u32 protkeytype instead. So the ioctl which still has to deal with this struct coming from userspace and/or provided to userspace invoke all the internal functions now with the triple instead of passing a pointer to struct pkey_protkey. Also the struct pkey_clrkey has been internally replaced in a similar way. This struct also has a hard coded clear key buffer of MAXCLRKEYSIZE = 32 bytes and thus is not usable with e.g. ECC clear key material. This is a transparent rework for userspace applications using the pkey API. The internal kernel API used by the PAES crypto ciphers has been adapted to this change to make it possible to provide ECC protected keys via this interface in the future.

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.
