Donenfeld" To: Linus Torvalds Cc: linux-kernel@vger.kernel.org Subject: [GIT PULL] random number generator fixes for 6.2-rc1, part 2 Date: Tue, 20 Dec 2022 03:24:58 +0100 Message-Id: <20221220022458.11682-1-Jason@zx2c4.com> MIME-Version: 1.0 Content-Transfer-Encoding: 8bit Precedence: bulk List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Hi Linus, As mentioned in the first pull for 6.2-rc1, this second late pull request has two remaining changes that are now possible after you merged a few other trees: - #include can be removed from random.h now, making the direct use of the arch_random_* API more of a private implementation detail between the archs and random.c, rather than something for general consumers. - Two additional uses of prandom_u32_max() snuck in during the initial phase of pulls, so these have been converted to get_random_u32_below(), and now the deprecated prandom_u32_max() alias -- which was just a wrapper around get_random_u32_below() -- can be removed. In addition, there is one fix: - Check efi_rt_services_supported() before attempting to use an EFI runtime function. This affected EFI systems that disable runtime services yet still boot via EFI (e.g. the reporter's Dell arm64 laptop), as well systems where EFI runtime services have been forcibly disabled, such as on PREEMPT_RT. On those machines, a very early and hard to diagnose crash would happen, preventing boot. Please pull. Thanks, Jason The following changes since commit 6feb57c2fd7c787aecf2846a535248899e7b70fa: Merge tag 'kbuild-v6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild (2022-12-19 12:33:32 -0600) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/crng/random.git tags/random-6.2-rc1-for-linus for you to fetch changes up to 3c202d14a9d73fb63c3dccb18feac5618c21e1c4: prandom: remove prandom_u32_max() (2022-12-20 03:13:45 +0100) ---------------------------------------------------------------- Random number generator fixes for Linux 6.2-rc1. ---------------------------------------------------------------- Jason A.
