@ibraheemdev @kingprotty Well, there is one cool use in the #Linux kernel #wireguard by @zx2c4: git.kernel.org/pub/scm/linux/…
v7 posted of the vDSO getrandom() series: lore.kernel.org/lkml/202211241… , with a stackless ChaCha20 implementation on x86-64, as well as a corresponding patch to wire this up for glibc from @adhemerval - github.com/bminor/glibc/c… . I'm daily driving this on my laptop's libc.
This RFC patchset for the Linux kernel proposes using an EFI non-volatile variable as a persistent RNG seed that the kernel's EFISTUB can manage transparently and automatically. Very cool if it works. A question about using variables that way. lore.kernel.org/linux-efi/2022…
#systemd's EFI bootloader, systemd-boot, will now pass the on-disk RNG seeds it manages directly to the Linux kernel, so that the RNG is seeded by them before userspace runs. github.com/systemd/system…
