compatibility problems Pages that are encrypted contain post encryption checksum on different location that normal checksum fields. Therefore, we should before decryption check this checksum to avoid unencrypting corrupted pages. After decryption we can use traditional checksum check to detect if page is corrupted or unencryption was done using incorrect key. Pages that are page compressed do not contain any checksum, here we need to fist unencrypt, decompress and finally use tradional checksum check to detect page corruption or that we used incorrect key in unencryption. buf0buf.cc: buf_page_is_corrupted() mofified so that compressed pages are skipped. buf0buf.h, buf_block_init(), buf_page_init_low(): removed unnecessary page_encrypted, page_compressed, stored_checksum, valculated_checksum fields from buf_page_t buf_page_get_gen(): use new buf_page_check_corrupt() function to detect corrupted pages. buf_page_check_corrupt(): If page was not yet decrypted check if post encryption checksum still matches. If page is not anymore encrypted, use buf_page_is_corrupted() traditional checksum method. If page is detected as corrupted and it is not encrypted we print corruption message to error log. If page is still encrypted or it was encrypted and now corrupted, we will print message that page is encrypted to error log. buf_page_io_complete(): use new buf_page_check_corrupt() function to detect corrupted pages. buf_page_decrypt_after_read(): Verify post encryption checksum before tring to decrypt. fil0crypt.cc: fil_encrypt_buf() verify post encryption checksum and ind fil_space_decrypt() return true if we really decrypted the page. fil_space_verify_crypt_checksum(): rewrite to use the method used when calculating post encryption checksum. We also check if post encryption checksum matches that traditional checksum check does not match. fil0fil.ic: Add missed page type encrypted and page compressed to fil_get_page_type_name() Note that this change does not yet fix innochecksum tool, that will be done in separate MDEV. Fix test failures caused by buf page corruption injection.
