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

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.
