If by that you mean "directly run userspace code in kernel space", then yes, it's impossible. Otherwise... it really, really depends what the content of this thing is. You can't run just anything in kernel space, it has to be code compiled for your kernel's environment. It also really, really depends on how it's stored and where. The kernel's capable of reading firmware
files on demand, I think, but from the sounds of it that's no file...

- way to do that is e.g. mount (somehow) that dll / any other library as a device and use it in a way of reading / writing to that
If this dll is userspace code that won't help because it will still be userspace code and unable to operate in kernel space.

Are there any other possibilities to solve that problem?
Extract the userspace code in userspace. Use the userspace code in userspace. Communicate
data, not program instructions, in and out of the kernel.

Hi all,
I am working on USB data monitoring on Fedora Core 9. Kernel 2.6.25 has a built-in module (the one that isn't loadable, but compiles and links statically with the kernel during compilation) to snoop USB data. It is in <kernel_source_code>/drivers/usb/mon/.

NAME
regulatory.bin, regulatory.db - The Linux wireless regulatory database
Description
regulatory.bin and regulatory.db are the files used by the Linux wireless subsystem to keep its regulatory database information.
regulatory.bin is read by crda upon the Linux kernel's request for regulatory information for a specific ISO / IEC 3166 alpha2 country
code.
regulatory.db is a newer, extensible database format which (since Linux 4.15) is read by the kernel directly as a firmware file.
The regulatory database is kept in a small binary format for size and code efficiency. The regulatory.bin file can be parsed and read in
human format by using the regdbdump command. The regulatory database files should be updated upon regulatory changes or corrections.
Upkeeping
The regulatory database is maintained by the community as such you are encouraged to send any corrections or updates to the linux-wireless
and wireless-regdb mailing lists: linux-wireless@vger.kernel.org and wireless-regdb@lists.infradead.org
