[PATCH net-next v2 0/5] BPF/random32 updates

[Daniel Borkmann <daniel@iogearbox.net>]

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
