[OS-BUILD PATCH 0/2] random: Add hook to override device reads and getrandom(2)
by Herbert Xu (via Email Bridge) 12 Feb '25

12 Feb '25

From: Herbert Xu on gitlab.com Merge Request: https://gitlab.com/cki-project/kernel-ark/-/merge_requests/2757 Upstream Status: RHEL only Restore the changes to /dev/random which were reverted after 5.18. This reverts commit 900f11e054896bae7b0146055698656e3d1e20a6 and 297bcb88233101e8d5062729ff3a5f989bad1c3b. This also brings the code up-to-date with respect to centos-stream commit 9de3a7339793d3c516b9305a8854267156f90c53 so that changes that were made after the kernel-ark revert have been brought in.

[OS-BUILD PATCHv3 0/0] random: Override random with FIPS RNG in FIPS mode
by Herbert Xu (via Email Bridge) 30 Jan '25

30 Jan '25

From: Herbert Xu on gitlab.com Merge Request: https://gitlab.com/cki-project/kernel-ark/-/merge_requests/1304 NOTE: Truncated patchset since committer email 'herbert(a)gondor.apana.org.au' does not match the submitter's GitLab public email address 'herbert.xu(a)redhat.com'. Upstream: RHEL only Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1984784 The RHEL FIPS certification effort ran into an show-stopper with /dev/urandom and getrandom(2) not being FIPS-compliant. At this point there is no realistic chance of making them FIPS-compliant upstream. It has also been deemed unrealistic to change user-space to use the FIPS-compliant RNG through the Crypto API. Therefore this patch series overrides /dev/*random as well as getrandom(2) with the Crypto API RNG so that FIPS certification can proceed.

[OS-BUILD PATCHv2] [redhat] configs: Compress kernel with zstd cleanup
by Jeremy Linton (via Email Bridge) 13 Dec '24

13 Dec '24

From: Jeremy Linton <jlinton(a)redhat.com> [redhat] configs: Compress kernel with zstd cleanup Zstd compressed kernels consume less disk space and decompress faster than gziped ones. For example, kernel 6.12rc3 aarch64's on disk size is ~22% smaller and boots ~16% faster on a RPi4. Since this was already on for some x86 flavors, lets propogate the setting to all appropriate architectures and kernel flavors.

[OS-BUILD PATCH] redhat: Drop bpftool from kernel spec
by Viktor Malik (via Email Bridge) 25 Nov '24

25 Nov '24

From: Viktor Malik <vmalik(a)redhat.com> redhat: Drop bpftool from kernel spec We are going to build bpftool as a separate package. There are 2 main reasons for this change: (1) bpftool version is independent of the kernel and having it in the kernel spec causes all kinds of problems and (2) bpftool is loosely coupled to the libbpf library which is also packaged separately. Note that bpftool is still built during kernel build in 2 places: - Bootstrap bpftool for generating vmlinux.h which goes into kernel-devel. - As a part of kernel BPF selftests build. Here, we opt to use the bpftool from kernel sources rather than the system one because upstream selftests sometimes require unreleased bpftool features to build successfully.

As a reminder, the ARK configuration flow involves moving unreviewed configuration options from the pending directory to the ark directory. In the diff below, options are removed from the pending directory and added to the ark hierarchy. The final options that need to be ACKed are the files that are being added to the ark hierarchy. If the value for a file that is added should be changed, please reply with a better option.

[OS-BUILD PATCHv2] redhat/configs: add bootconfig to kernel-tools package
by Brian Masney (via Email Bridge) 31 Oct '24

31 Oct '24

From: Brian Masney <bmasney(a)redhat.com> redhat/configs: add bootconfig to kernel-tools package Upstream Status: RHEL Only Add the bootconfig binary to the kernel-tools package. CONFIG_BOOT_CONFIG is already enabled in RHEL and this allows having a separate file with the kernel parameters and is described at https://docs.kernel.org/admin-guide/bootconfig.html. We intend to use this for automotive for testing purposes since some embedded platforms limit the kernel command line paramters to 511 bytes.
