[Qemu-devel] [PATCH v3 0/4] fw_cfg: Add edk2_add_host_crypto_policy()

[Philippe Mathieu-Daudé]

Hi,

This series consists of:
- add fw_cfg_add_file_from_host()
- add edk2_add_host_crypto_policy() and the Edk2Crypto object

The Edk2Crypto object is used to hold configuration values specific
to EDK2.

The edk2_add_host_crypto_policy() function loads crypto policies
from the host, and register them as fw_cfg named file items.

So far only the 'https' policy is supported.

A usercase example is the 'HTTPS Boof' feature of OVMF [*].

Usage example:

$ qemu-system-x86_64 \
    --object edk2_crypto,id=https,\
        ciphers=/etc/crypto-policies/back-ends/openssl.config,\
        cacerts=/etc/pki/ca-trust/extracted/edk2/cacerts.bin

(On Fedora these files are provided by the ca-certificates and
crypto-policies packages).

Since v2:
- Split of
Since v1:
- Addressed Michael and Laszlo comments.

Please review,

Phil.
