Subject: [PATCH v2 0/1] Fix and improve zcrypt reply message checks
Date: Tue, 8 Sep 2026 15:18:15 +0200 [thread overview]
Message-ID: <20260908131817.17644-1-freude@linux.ibm.com> (raw)
Fix and improve zcrypt reply messages checks of type 6 - CCA and EP11
- and type 50 - ICA.
Changelog:
v1: Initial version
v2: Sashiko complained about not checking offset1/count1 at all if
count2 for an CCA type6 reply is given. And a check like this was
in place before the rework. So now offset1/count1 is always
checked and only if count2 is non zero offset2/count2 is
additionally checked.
