Subject: [PATCH 0/4] kexec/arm64: Add support for zlib compressed kernel images (Image.gz)
Date: Thu, 11 Jul 2019 01:24:25 +0530 [thread overview]
Message-ID: <1562788469-22935-1-git-send-email-bhsharma@redhat.com> (raw)
This patchset adds the support for zlib compressed kernel images
(Image.gz) for arm64 kexec-tools.
This was discussed a bit with the arm64 kernel maintainers (see [0]) and
after discussing the pros and cons of adding this support in
kernel-space v/s in user-space, we decided it makes more sense to add
this support to the user-space kexec-tools.
Note that this series adds support for unsigned arm64 Image.gz files
only as signing an Image.gz type file is not a easy implementation from
kexec-tools p-o-v. Also even standard signing tools like sbsign fail to
recongize the Image.gz format:
$ sbsign --key certs/signing_key.pem --cert certs/signing_key.pem Image.gz
Invalid DOS header magic
... because that gzip file isn't a PE32+ that can be loaded by UEFI.
So I will work on the same in coming days and try to send a RFC
patchset for the same later on.
