[PATCH 0/3] lib/crypto: Provide functions for zeroizing SHA2 hmac_sha* structures

[Thomas Huth]

This patch series has been split of my earlier zeroization patch
series since there were some troubles left with the purgatory patch:

 https://lore.kernel.org/all/20260924145806.GA1949494@ax162/

As I've confirmed now, the fix for the problem is indeed to set
-D__DISABLE_EXPORTS for the other files in the x86 purgatory, too,
so the first patch here has now been changed accordingly.

Thomas Huth (3):
  x86/purgatory: Compile purgatory with -D__NO_FORTIFY and
    -D__DISABLE_EXPORTS
  lib/crypto: sha2: Provide functions for zeroizing SHA2 hmac_sha*
    structures
  smb: client: Use hmac_sha256_zeroize_ctx function to clear
    hmac_sha256_ctx
