[OS-BUILD PATCH] redhat: add IMA certificates

by Jan Stancek (via Email Bridge)

From: Jan Stancek <jstancek(a)redhat.com> redhat: add IMA certificates Forward port c9s commit: 7ff63254426d ("redhat: add IMA certificates") Starting with RHEL9.0, installed package files will have IMA signatures if users choose so. The IMA subsystem will search for the certificate in the .ima keyring to verify a file signature thus to make sure this file hasn't been tampered with. To be able to add the IMA code-signing certificate to the .ima keyring, this certificate needs to be signed by a CA certificate in the system keyrings. This patch builds the IMA CA certificate into the .builtin_trusted_keys keyring and installs the IMA code-signing certificate to /usr/share/doc/kernel-keys/KVERREL/ima.cer for user space tools like dracut to add it the .ima keyring.

[OS-BUILD PATCH] redhat/configs: enable CONFIG_LEDS_TRIGGER_NETDEV also for RHEL

by Michal Schmidt (via Email Bridge)

From: Michal Schmidt <mschmidt(a)redhat.com> redhat/configs: enable CONFIG_LEDS_TRIGGER_NETDEV also for RHEL JIRA: https://issues.redhat.com/browse/RHEL-32110 The igc NIC driver exposes sysfs-controllable LEDs since commit ea578703b03d ("igc: Add support for LEDs on i225/i226"). It makes sense to use the netdev trigger to control them. CONFIG_LEDS_TRIGGER_NETDEV is already enabled for Fedora. Enable it also for RHEL.

[OS-BUILD PATCHv17 0/2] redhat/kernel.spec: add uki_addons to create UKI kernel cmdline addons

by Emanuele Giuseppe Esposito (via Email Bridge)

From: Emanuele Giuseppe Esposito on gitlab.com Merge Request: https://gitlab.com/cki-project/kernel-ark/-/merge_requests/2917 We want to enable kernel.spec to optionally ship UKI addons defined in a common config file in redhat folder. The folder redhat/uki_addons will contain all addons configs specifying the UKI kernel cmdline addons to be created in the next build. An addon config is simply a .addon plain text file, where any line is taken as kernel cmdline, except for the ones starting with '#', which will be automatically ignored. redhat/scripts/uki_addons.py will take care of parsing all configs and folders in redhat/uki_addons and call 'ukify' to create the actual addons. The output addon filename will be a concatenation of all folders in redhat/uki_addons that are part of the addon config path. The folder hierarchy inside of redhat/uki_addons is similar to redhat/configs: $distro/$UKI_NAME/%arch. It is also possible to add .sbat to all the generated addons, by populating redhat/addons/$distro/$UKI_NAME/%arch/sbat/sbat.conf. Syntax is same as the addons config. At build time, Makefile will create a tar.gz archive (uki_addons.tar.gz) containing all the files in redhat/uki_addons. It will then passed to the kernel specfile that will extract the addons from it and generate the UKI kernel cmdline addons. As an example of this feature, add the fips addon to optionally enable fips (https://issues.redhat.com/browse/RHEL-23049). --- redhat/scripts/uki_addons.py | 162 +++++++++++++++++++++++++++++++ redhat/uki_addons/virt/common/fips.addon | 1 + redhat/Makefile | 3 + redhat/kernel.spec.template | 44 ++++++++ 4 files changed, 210 insertions(+), 0 deletions(-)
