crypto_grab_*() doesn't set crypto_spawn::inst, so templates must set it
beforehand. Otherwise it will be left NULL, which causes a crash in
certain cases where algorithms are dynamically loaded/unloaded. E.g.
with CONFIG_CRYPTO_CHACHA20_X86_64=m, the following caused a crash:
insmod chacha-x86_64.ko
python -c 'import socket; socket.socket(socket.AF_ALG, 5, 0).bind(("skcipher", "adiantum(xchacha12,aes)"))'
rmmod chacha-x86_64.ko
python -c 'import socket; socket.socket(socket.AF_ALG, 5, 0).bind(("skcipher", "adiantum(xchacha12,aes)"))'

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.
