Donenfeld" <Jason@...c4.com> Subject: [PATCH 0/3] random: wire up in-kernel virtual machine fork notifications As discussed, here is the notifier for learning when a virtual machine forks, as well as a first use case for it, which is unsurprisingly WireGuard, since I happen to know that case rather well. The first patch is a small cleanup discovered when working on the second patch, which is adding the actual notifier. The third case then trivially adds it to WireGuard. Jason A. Donenfeld (3): random: replace custom notifier chain with standard one random: provide notifier for VM fork wireguard: device: clear keys on VM fork drivers/char/random.c | 82 ++++++++++++++-------------------- drivers/net/wireguard/device.c | 27 +++++------ include/linux/random.h | 16 +++---- lib/random32.c | 12 ++--- lib/vsprintf.c | 10 +++-- 5 files changed, 69 insertions(+), 78 deletions(-) -- 2.35.1
