5905ccea4bda233d719f0df900fcd5a4563d2886 - UPSTREAM: fdt_support: add optional board_rng_seed() hook

Mon, 11 Sep 2023 02:46:34 +0000

UPSTREAM: fdt_support: add optional board_rng_seed() hookA recurring theme on LKML is the boot process deadlocking due to someprocess blocking waiting for random numbers, while the kernel'sCryptographic Random Number Generator (crng) is not initalized yet,but that very blocking means no activity happens that would generatethe entropy necessary to finalize seeding the crng.This is not a problem on boards that have a good hwrng (when thekernel is configured to trust it), whether in the CPU or in a TPM orelsewhere. However, that's far from all boards out there. Moreover,there are consumers in the kernel that try to obtain random numbersvery early, before the kernel has had any chance to initialize anyhwrng or other peripherals.Allow a board to provide a board_rng_seed() function, which isresponsible for providing a value to be put into the rng-seed propertyunder the /chosen node.The board code is responsible for how to actually obtain thosebytes.- One possibility is for the board to load a seed "file" from somewhere (it need not be a file in a filesystem of course), and then ensure that that the same seed file does not get used on subsequent boots. * One way to do that is to delete the file, or otherwise mark it as invalid, then rely on userspace to create a new one, and living with the possibility of not finding a seed file during some boots. * Another is to use the scheme used by systemd-boot and create a new seed file immediately, but in a way that the seed passed to the kernel and the new (i.e. next) seed cannot be deduced from each other, see the explanation at https://lore.kernel.org/lkml/20190929090512.GB13049@gardel-login/ and the current code at https://github.com/systemd/systemd/blob/main/src/boot/efi/random-seed.c- The board may have an hwrng from which some bytes can be read; while the kernel can also do that, doing it in U-Boot and providing a seed ensures that even very early users in the kernel get good random numbers.- If the board has a sensor of some sort (temperature, humidity, GPS, RTC, whatever), mixing in a reading of that doesn't hurt.- etc. etc.These can of course be combined.The rng-seed property is mixed into the pool used by the linuxkernel's CRNG very early during boot. Whether it then actuallycontributes towards the kernel considering the CRNG initializeddepends on whether the kernel has been configured withCONFIG_RANDOM_TRUST_BOOTLOADER (nowadays overridable via therandom.trust_bootloader command line option). But that's for the BSPdeveloper to ultimately decide.So, if the board needs to have all that logic, why not also just haveit do the actual population of /chosen/rng-seed in ft_board_setup(),which is not that many extra lines of code?I considered that, but decided handling this logically belongs infdt_chosen(). Also, apart from saving the board code from the fewlines of boilerplate, doing it in ft_board_setup() is too late for atleast some use cases. For example, I want to allow the board logic todecide ok, let's pass back this buffer and use that as seed, but also let's set random.trust_bootloader=n so no entropy is credited.This requires the rng-seed handling to happen before bootargshandling. For example, during the very first boot, the board might nothave a proper seed file, but the board could still return (a hash of)some CPU serial# or whatnot, so that at least no two boards ever getthe same seed - the kernel always mixes in the value passed inrng-seed, but if it is not "trusted", the kernel would still gothrough the same motions as it would if no rng-seed was passed beforeconsidering its CRNG initialized. I.e., by returning thatunique-to-this-board value and setting random.trust_bootloader=n, theboard would be no worse off than if board_rng_seed() returned nothingat all.Signed-off-by: Rasmus Villemoes (cherry picked from commit 6dca1d9ad38de9b7f9a44d2c6eaa6acf9be6c2c0)Change-Id: I9838bccc384ff6d52505ed48815f8e599f0a7ee1Signed-off-by: Joseph Chen List of files: /rk3399_rockchip-uboot/common/Kconfig
