[OS-BUILD PATCHv4] redhat/configs: enable CONFIG_BLK_DEV_ZONED
by Ming Lei (via Email Bridge) 20 Jul '21

20 Jul '21

From: Ming Lei <ming.lei(a)redhat.com> redhat/configs: enable CONFIG_BLK_DEV_ZONED Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1638087 This option has been enabled in Fedora already. Also it is mentioned in this BZ that 'our current plan is to enable this in RHEL 9 first', so enable this option in redhat/configs/common so that people can use ZNS via userspace or play it via nvme-cli.

[OS-BUILD PATCH 0/0] [redhat] Generate a crashkernel.conf for each kernel build
by Kairui Song (via Email Bridge) 02 Jul '21

02 Jul '21

From: Kairui Song on gitlab.com Merge Request: https://gitlab.com/cki-project/kernel-ark/-/merge_requests/1171 NOTE: Truncated patchset due to missing public @redhat.com email address on your GitLab profile at https://gitlab.com/-/profile. Once that is fixed, close and reopen the merge request to retrigger sending the emails. It has been a long-term demand for having a default crashkernel value for each kernel build. This helps to manage kernel's crashkernel usage by kernel version and provide users a reference default value. RHEL kernels support a `crashkernel=auto` cmdline param. And kernel have a built-in default value used when `auto` is specified. Many attempts are made to push this upstream. Recent attempt to push this upstream raised a lot of discussions [1]. Upstream is not accepting this `crashkernel=auto` design. So after more discussions, instead of adding a default value in kernel, just add a config that packaged with kernel is more doable. Other packages, like kexec-tools[2], can use this as a reference and update kernel cmdline param.

[OS-BUILD PATCH] rpmspec: only build debug meta packages where we build debug ones
by Herton R. Krzesinski (via Email Bridge) 30 Jun '21

30 Jun '21

From: Herton R. Krzesinski <herton(a)redhat.com> rpmspec: only build debug meta packages where we build debug ones Previous commit "rpmspec: build debug-* meta-packages if debug builds are disabled" failed to consider the architectures or cases where we disable debug packages, and made meta packages being built for them even if real debug package build was disabled in the normal case. So eg. for arches we don't build kernels (eg. i686) debug meta packages could appear even if we don't have kernel/kernel-debug being built. This adds some logic to see if really with_debug was enabled, and creating the meta-package only when it is enabled/set. Signed-off-by: Herton R.

[OS-BUILD PATCH] Revert "Merge branch 'ec_fips' into 'os-build'"
by Vladis Dronov (via Email Bridge) 30 Jun '21

30 Jun '21

From: Vladis Dronov <vdronov(a)redhat.com> Revert "Merge branch 'ec_fips' into 'os-build'" We need to revert the merge request !1150 and make CONFIG_CRYPTO_ECDH and CONFIG_CRYPTO_ECDSA back to =m. Current =y setting prevents a kernel booting in FIPS mode. This blocks some processes, see bz1915290#c23. This is an upstream issue and we need this revert until a proposed upstream solution is fully tested.
