[PATCH v2 0/3] Replace invocations of prandom_u32_state, prandom_bytes_state with get_random_u32, get_random_bytes

Posted by david.keisarschm@mail.huji.ac.il 2 years, 9 months ago

From: David <david.keisarschm@mail.huji.ac.il>

 The security improvements for prandom_u32 done specifically in
commits c51f8f88d705e06bd696d7510aff22b33eb8e638 from October 2020
 and d4150779e60fb6c49be25572596b2cdfc5d46a09 from May 2022)
 didn't handle the cases when prandom_bytes_state() and prandom_u32_state()
  are used. We have now added the necessary changes to handle
   these cases as  well.

David (3):
  Replace invocation of weak PRNG in mm/slab.c
  Replace invocation of weak PRNG inside mm/slab_common.c
  Replace invocation of weak PRNG in arch/x86/mm/kaslr.c
