Jan Lindström	509b836623	MDEV-8708: InnoDB temp file encryption Added encryption support for online alter table where InnoDB temporary files are used. Added similar support also for tables containing full text-indexes. Made sure that table remains encrypted during discard and import tablespace.	10 years ago
Jan Lindström	e1978234eb	MDEV-8588: Assertion failure in file ha_innodb.cc line 21140 if at least one encrypted table exists and encryption service is not available Analysis: Problem was that in fil_read_first_page we do find that table has encryption information and that encryption service or used key_id is not available. But, then we just printed fatal error message that causes above assertion. Fix: When we open single table tablespace if it has encryption information (crypt_data) store this crypt data to the table structure. When we open a table and we find out that tablespace is not available, check has table a encryption information and from there is encryption service or used key_id is not available. If it is, add additional warning for SQL-layer.	10 years ago
Jan Lindström	bfb6ea0232	MDEV-8589: Non-default ENCRYPTION_KEY_ID is ignored upon reading a table Analysis: Problem was that when a new tablespace is created a default encryption info is also created and stored to the tablespace. Later a new encryption information was created with correct key_id but that does not affect on IV. Fix: Push encryption mode and key_id to lower levels and create correct encryption info when a new tablespace is created. This fix does not contain test case because, currently incorrect encryption key causes page corruption and a lot of error messages to error log causing mtr to fail.	10 years ago

Jan Lindström	53623d932a	MDEV-8522: InnoDB: Assertion failure in file fil0fil.cc line 475 Analysis: In fil_crypt_space_needs_rotation we first make sure that tablespace is found and then separately that it is normal tablespace. Thus, tablespace could be dropped between these two functions calls. Fix: If space is not found from fil_system return tablespace type ULINT_UNDEFINED and naturally do not continue rotating space.	10 years ago

Sergei Golubchik	fe7e334f3e	cleanup: remove unused function argument	10 years ago
Jan Lindström	d7f3d889de	MDEV-8272: Encryption performance: Reduce the number of unused memcpy's Removed memcpy's on cases when page is not encrypted and make sure we use the correct buffer for reading/writing.	11 years ago
Jan Lindström	2bea4bd9ed	MDEV-8233: InnoDB: Assertion failure in fil_page_decompress with encrypted tables Analysis: Problem was that used compression method needs to be stored to the page. Fixed by storing compression method after key_version to the page.	11 years ago
Jan Lindström	536112dd30	MDEV-8195: InnoDB: Error: trying to access tablespace 11262 page no. 7, InnoDB: but the tablespace does not exist or is just being dropped. Analysis: Problem was that we did try to read from tablespace that was being dropped. Fixed by introducing a new function to find a tablespace only if it is not being dropped currently and adding this check before trying to read pages from tablespace.	11 years ago
Jan Lindström	925b64124a	MDEV-8182: Failing assertion: 1 == UT_LIST_GET_LEN(space->chain) Analysis: At fil_spage_get_space there is small change that space is found from tablespace list but we have not yet created node for it (and added it to space->chain) and as we hold fil_system mutex here fil_node_create can't continue. Fixed by allowing UT_LIST_GET_LEN(space->chain) == 0\|\| 1 and introducint two new functions that access filespace list and before returning space check that node is also created.	11 years ago
Jan Lindström	3e55ef26d4	MDEV-8173: InnoDB; Failing assertion: crypt_data->type == 1 Make sure that when we publish the crypt_data we access the memory cache of the tablespace crypt_data. Make sure that crypt_data is stored whenever it is really needed. All this is not yet enough in my opinion because: sql/encryption.cc has DBUG_ASSERT(scheme->type == 1) i.e. crypt_data->type == CRYPT_SCHEME_1 However, for InnoDB point of view we have global crypt_data for every tablespace. When we change variables on crypt_data we take mutex. However, when we use crypt_data for encryption/decryption we use pointer to this global structure and no mutex to protect against changes on crypt_data. Tablespace encryption starts in fil_crypt_start_encrypting_space from crypt_data that has crypt_data->type = CRYPT_SCHEME_UNENCRYPTED and later we write page 0 CRYPT_SCHEME_1 and finally whe publish that to memory cache.	11 years ago
Jan Lindström	20c23048c1	MDEV-8164: Server crashes in pfs_mutex_enter_func after fil_crypt_is_closing or alike Analysis: Problem was that tablespaces not encrypted might not have crypt_data stored on disk. Fixed by always creating crypt_data to memory cache of the tablespace. MDEV-8138: strange results from encrypt-and-grep test Analysis: crypt_data->type is not updated correctly on memory cache. This caused problem with state tranfer on encrypted => unencrypted => encrypted. Fixed by updating memory cache of crypt_data->type correctly based on current srv_encrypt_tables value to either CRYPT_SCHEME_1 or CRYPT_SCHEME_UNENCRYPTED.	11 years ago
Sergei Golubchik	54672a4f1e	MDEV-8043 innodb tablespace encryption "use after free" bug, when a thread replaces space->crypt_data and frees the old crypt_data object while it's being used by another thread.	11 years ago
Jan Lindström	f8cacd03a7	MDEV-8143: InnoDB: Database page corruption on disk or a failed file read Analysis: Problem was that we did create crypt data for encrypted table but this new crypt data was not written to page 0. Instead a default crypt data was written to page 0 at table creation. Fixed by explicitly writing new crypt data to page 0 after successfull table creation.	11 years ago
