AES_CBC can be used for binlog files encryption
The AES_CBC could leaves some not handled bytes in the buffer and those
need a special encoding (ECB and XOR)
This way the output buffer of the whole encoding with AES_CBC will have
same size as the input (AES_CTR does it without any other step)
First implementation of Binlog server binary encryption
Limitations:
AES_CTR only is supported
events larger than 16MBytes are not encrypted.
Maxscale binary log files can be read by a MaraDB 10.1 server which set
same AES key and algorithm
When a hole is detected while receiving events an ignorable event is
written in maxscale binlog. Such event is not sent ti slave servers.
Maxbinlogcheck can now check encrypted binlog files without decrypting
them
- All now include maxscale/cdefs.h as the very first file.
- MXS_[BEGIN|END]_DECLS added to all C-headers.
Strictly speaking not necessary for private headers, but
does not hurt either.
- Include guards moved to the very top of the file.
- #pragma once added.
