2020-09-10crypto/gcrypt: Split QCryptoCipherGcrypt into subclassesRichard Henderson1-255/+238
With gcrypt, most of the dispatch happens in the library, so there aren't many classes to create. However, we can still create separate dispatch for CTR mode, and for CONFIG_QEMU_PRIVATE_XTS, which avoids needing to check for these modes at runtime.

2020-09-10crypto: Move cipher->driver init to qcrypto_*_cipher_ctx_newRichard Henderson1-0/+2
The class vtable should be set by the class initializer. This will also allow additional subclassing, reducing the amount of indirection in the hierarchy. Signed-off-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Daniel P. Berrangé <berrange@redhat.com>
2020-09-10crypto: Allocate QCryptoCipher with the subclassRichard Henderson1-10/+13
Merge the allocation of "opaque" into the allocation of "cipher". This is step one in reducing the indirection in these classes. Signed-off-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Daniel P. Berrangé <berrange@redhat.com>
2020-09-10crypto: Use the correct const type for driverRichard Henderson1-1/+1
This allows the in memory structures to be read-only. Signed-off-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Daniel P. Berrangé <berrange@redhat.com>
2020-09-10crypto: Remove redundant includesRichard Henderson1-2/+0
Both qemu/osdep.h and cipherpriv.h have already been included by the parent cipher.c. Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> Signed-off-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Daniel P. Berrangé <berrange@redhat.com>
2020-09-10crypto: Rename cipher include files to .c.incRichard Henderson1-0/+423
QEMU standard procedure for included c files is to use *.c.inc. E.g. there are a different set of checks that are applied. Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> Signed-off-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Daniel P. Berrangé <berrange@redhat.com>
