[OS-BUILD PATCH] [redhat] New configs in drivers/dma
by CKI ARK Bot (via Email Bridge) 03 Feb '25

03 Feb '25

From: Fedora Kernel Team <kernel-team(a)fedoraproject.org> [redhat] New configs in drivers/dma Hi, As part of the ongoing rebase effort, the following configuration options need to be reviewed. 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 PATCH] not upstream: Set vdso is_ready later during boot process
by Herbert Xu (via Email Bridge) 31 Jan '25

31 Jan '25

From: Herbert Xu <herbert.xu(a)redhat.com> not upstream: Set vdso is_ready later during boot process Instead of setting vdso is_ready when the CRNG becomes ready, do it later in the boot process as FIPS mode itself may not have been set yet during the early-boot stages. In particular, the CRNG gets initialised very early on arm64, even before the early boot paramaters are parsed. Delaying vdso is_ready setting on the other hand is harmless as there is always a fallback code path that leads to getrandom(2).

[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.
