%description

libkcapi allows user-space to access the Linux kernel crypto API.

This library uses the netlink interface and exports easy to use APIs

so that a developer does not need to consider the low-level netlink

interface handling.

The library does not implement any cipher algorithms.  All consumer

requests are sent to the kernel for processing.  Results from the

kernel crypto API are returned to the consumer via the library API.

The kernel interface and therefore this library can be used by

unprivileged processes.

%{__cat} << EOF > README.%{distroname_ext}

This package increases the default limit of the ancillary buffer size

per kernel socket defined in \`net.core.optmem_max\` to %{sysctl_optmem_max} bytes.

For this preset to become active it requires a reboot after the

installation of this package.  You can also manually increase this

limit by invocing \`sysctl net.core.optmem_max=%{sysctl_optmem_max}\` as the

super-user, e.g. using \`su\` or \`sudo\` on the terminal.

This is done to provide consumers of the new Linux Kernel Crypto API

User Space Interface a well sufficient and reasonable maximum limit

by default, especially when using AIO with a larger amount of IOVECs.

For further information about the AF_ALG kernel socket and AIO, see

the discussion at the kernel-crypto mailing-list:

https://www.mail-archive.com/linux-crypto@vger.kernel.org/msg30417.html

See the instructions given in '%{_sysctldir}/50-default.conf',

if you need or want to override the preset made by this package.
