Stefan Berger 458458c130 crypto: ecdsa - Fix module auto-load on add-key 
commit 48e4fd6d54 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. Create certificate

  openssl req -x509 -sha256 -newkey ec \
  -pkeyopt "ec_paramgen_curve:secp384r1" -keyout key.pem -days 365 \
  -subj '/CN=test' -nodes -outform der -out nist-p384.der

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

3. Trigger add_key call for the cert:

   # keyctl padd asymmetric "" @u < nist-p384.der
   641069229
   # lsmod | head -2
   Module                  Size  Used by
   ecdsa_generic          16384  0

README

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.
