BPF update to split the prandom state apart, and to move the
*once helpers to the core. For details, please see individual
patches. Given the changes and since it's in the tree for
quite some time, net-next is a better choice in our opinion.
v1 -> v2:
- Make DO_ONCE() type-safe, remove the kvec helper. Credits
go to Alexei Starovoitov for the __VA_ARGS__ hint, thanks!
- Add a comment to the DO_ONCE() helper as suggested by Alexei.
- Rework prandom_init_once() helper to the new API.
- Keep Alexei's Acked-by on the last patch.
Thanks!
Daniel Borkmann (3):
random32: add prandom_seed_full_state helper
random32: add prandom_init_once helper for own rngs
bpf: split state from prandom_u32() and consolidate {c,e}BPF prngs
Hannes Frederic Sowa (2):
net: move net_get_random_once to lib
once: make helper generic for calling function once
