[v2,0/4] crypto: use kfree_sensitive()

Message

Denis Efremov (Oracle) Aug. 27, 2020, 6:43 a.m. UTC

kfree_sensitive() is introduced in commit 453431a54934
("mm, treewide: rename kzfree() to kfree_sensitive()") and uses
memzero_explicit() internally. Thus, we can switch to this API
instead of open-coding memzero_explicit() && kfree().

Changes in v2:
 - if (op->len) check removed

Denis Efremov (4):
  crypto: inside-secure - use kfree_sensitive()
  crypto: amlogic - use kfree_sensitive()
  crypto: sun8i-ce - use kfree_sensitive()
  crypto: sun8i-ss - use kfree_sensitive()
