Andrew Kryczka 5d6005c780 Add WriteOptions::protection_bytes_per_key (#10037) ... Summary: Added an option, `WriteOptions::protection_bytes_per_key`, that controls how many bytes per key we use for integrity protection in `WriteBatch`. It takes effect when `WriteBatch::GetProtectionBytesPerKey() == 0`. Currently the only supported value is eight. Invoking a user API with it set to any other nonzero value will result in `Status::NotSupported` returned to the user. There is also a bug fix for integrity protection with `inplace_callback`, where we forgot to take into account the possible change in varint length when calculating KV checksum for the final encoded buffer. Pull Request resolved: https://github.com/facebook/rocksdb/pull/10037 Test Plan: - Manual - Set default value of `WriteOptions::protection_bytes_per_key` to eight and ran `make check -j24` - Enabled in MyShadow for 1+ week - Automated - Unit tests have a `WriteMode` that enables the integrity protection via `WriteOptions` - Crash test - in most cases, use `WriteOptions::protection_bytes_per_key` to enable integrity protection Reviewed By: cbi42 Differential Revision: D36614569 Pulled By: ajkr fbshipit-source-id: 8650087ceac9b61b560f1e5fafe5e1baf9c725fb		3 years ago
