- Fix matching /boot and /lib/firmware in pesign-repackage.spec - Do not store the buildroot in the .*.hmac file. - Regenerate the HMAC checksum when signing and EFI binary with a checksum (fate#316930, bnc#856310). - Update README. - Add /usr/lib/rpm/pesign/gen-hmac tool to generate a hmac checksum for a given file (fate#316930, bnc#856310).

Signing kernel modules and EFI binaries in the Open Build Service
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Packages that need to sign files during build should add the following lines
|
|
to the specfile
|
|
|
|
# needssslcertforbuild
|
|
export BRP_PESIGN_FILES='pattern...'
|
|
BuildRequires: pesign-obs-integration
|
|
|
|
The "# needssslcertforbuild" comment tells the buildservice to store the
|
|
signing certificate in %_sourcedir/_projectcert.crt. At the end of the
|
|
install phase, the brp-99-pesign script computes hashes of all
|
|
files matching the patterns in $BRP_PESIGN_FILES. The sha256 hashes are stored
|
|
in %_topdir/OTHER/%name.cpio.rsasign, plus the script places a
|
|
pesign-repackage.spec file there. When the first rpmbuild finishes, the
|
|
buildservice sends the cpio archive to the signing server, which returns
|
|
a rsasigned.cpio archive with RSA signatures of the sha256 hashes.
|
|
|
|
The pesign-repackage.spec takes the original RPMs, unpacks them and
|
|
appends the signatures to the files. It then uses the
|
|
pesign-gen-repackage-spec script to generate another specfile, which
|
|
builds new RPMs with signed files. The supported file types are:
|
|
|
|
/lib/firmware/* - Detached signature in $file.sig
|
|
*.ko - Signature appended to the module
|
|
efi binaries - Signature embedded in a header. If a HMAC checksum named
|
|
.$file.hmac exists, it is regenerated
