s390/monwriter: Reject buffer reuse with different data length (2026-07-02 16:51:06 +0200)
----------------------------------------------------------------
s390 updates for 7.2-rc2
- Fix PKEY_VERIFYPROTK ioctl key type handling by removing the generic
key-length based type check with its wrong bit-size calculation,
and leaving protected key verification to the pkey handler
- Fix monwriter buffer reuse by rejecting records that change the data
length, preventing out of bounds user copy into the kernel buffer
