Vitaly Chikunov 95abba5168 crypto: ecrdsa - Fix module auto-load on add_key
commit eb5739a1ef upstream.

Add module alias with the algorithm cra_name similar to what we have for
RSA-related and other algorithms.

The kernel attempts to modprobe asymmetric algorithms using the names
"crypto-$cra_name" and "crypto-$cra_name-all." However, since these
aliases are currently missing, the modules are not loaded. For instance,
when using the `add_key` function, the hash algorithm is typically
loaded automatically, but the asymmetric algorithm is not.

Steps to test:

1. Cert is generated usings ima-evm-utils test suite with
   `gen-keys.sh`, example cert is provided below:

  $ base64 -d >test-gost2012_512-A.cer <<EOF
  MIIB/DCCAWagAwIBAgIUK8+whWevr3FFkSdU9GLDAM7ure8wDAYIKoUDBwEBAwMFADARMQ8wDQYD

  KYLOcO4xK3Whwa2hBAz9YbpUSFjvxnkS2/jpH2MsOSXuUEeCruG/RkHHB3ACef9umG6HCNQuAPY=
  EOF

2. Optionally, trace module requests with: trace-cmd stream -e module &

3. Trigger add_key call for the cert:

  # keyctl padd asymmetric "" @u <test-gost2012_512-A.cer
  939910969
  # lsmod | head -3
  Module                  Size  Used by
  ecrdsa_generic         16384  0
  streebog_generic       28672  0

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.
