Add hash testing of unaligned buffer sizes via multiple call to
ioctl(CIOCCRYPT) in a single session with buffer sizes incrementally increasing
from zero size to 255 (with monotoncially increasing byte value data) to force
all sizes to be handled by cryptodev implementations.
## Summary
The Crypto API is silent on buffer size alignment and there is no testing
that provides unaligned buffer sizes to ioctl(CIOCRYPT) in one session. This
patch extends hash test utility (and adds Kconfig option to enable/disable)
that starets with a zero-sized buffer passed to ioctl(CIOCCRYPT), then a
one-byte buffer, then a two byt buffer and so on to stress the underlying
cryptodev device's handling of unaligned buffers/sizes. The test continually
increments the size of the buffer passed to ioctl(CIOCCRYPT) until its 255
bytes in length (causing underlying cryptodev to hash 32640 bytes of data). The
data provided through all thes incrementally size increasing buffers is
monotonically increassing bytes starting at 0x00.
## Impact
- User experience: No adaptation required. This fix extends existing
behavior.
- Build: No impact.
- Hardware: No impact.
- Documentation: No impact.
- Security: No impact.
- Compatibility: Backward compatible - adds testing functionality.
## Testing
Build Host:
- OS: Ubuntu 24.04.4 LTS
- Compiler: arm-none-eabi-gcc 13.2.1
Target:
- Architecture: ARM (STM32H753ZI)
- Board: Nucleo-h753zi
- Configuration: nucleo-h753zi:crypto - then:
- Disable cryptodev hardware support
- Enable Crypto API Software library support
- Enable Crypto API cryptodev software cipher support
- In Application Configuration:
- Under Testing/drivers:
- Enable hash unaligned buffer size test
Testing performed:
- Booted board and ran hash test utilities; verify hash test utilities with
cryptodev software implementation.
Runtime testing:
