description |
Description: kernel: Fix memory leak on CCA and EP11 CPRB processing.
Symptom: Kernel memory not freed when CCA or EP11 CPRB processing fails.
Problem: kfree() in code error path missing.
Solution: Slight rework of the malloc and free places.
Reproduction: Run application which sends CCA or EP11 crypto requests
to the crypto card(s). Now switch the cards offline with
the help of chzcrypt. Monitor top or free output.
Upstream commit(s): kernel 4.18
