…itialization vector bug (apache#17420)" This reverts commit 397cc01.
…nitialization vector bug (apache#17420) ECB algorithm, block_encryption_mode does not take effect, it only takes effect when init vector is provided. Solved: 192/256 supports calculation without init vector For other algorithms, an error should be reported when there is no init vector Initialization Vector. The default value for the block_encryption_mode system variable is aes-128-ecb, or ECB mode, which does not require an initialization vector. The alternative permitted block encryption modes CBC, CFB1, CFB8, CFB128, and OFB all require an initialization vector. Reference: https://dev.mysql.com/doc/refman/8.0/en/encryption-functions.html#function_aes-decrypt Note: This fix does not support smooth upgrades. during upgrade process, query may report error: funciton not found

Issue Number: close #xxx
Problem summary
The first fix: #17420, there is a compatibility problem,
So add aes/sm4 V2 function to support correct behavior.
The original aes/sm4 still maintains the previous behavior.

Initialization Vector. The default value for the block_encryption_mode system variable is aes-128-ecb, or ECB mode, which does not require an initialization vector. The alternative permitted block encryption modes CBC, CFB1, CFB8, CFB128, and OFB all require an initialization vector.
