Change subject: IMPALA-6219: Use AES-GCM for spill-to-disk encryption ...................................................................... IMPALA-6219: Use AES-GCM for spill-to-disk encryption AES-GCM can be very fast(~10 times faster than CFB+SHA256), but it requires an instruction that Impala can currently run without (CLMUL). In order to be fast, we dispatch to GCM mode at run-time based on the CPU and OpenSSL version. Testing: run runtime tmp-file-mgr-test, openssl-util-test, buffer-pool-test and buffered-tuple-stream-test. add two cases GcmIntegrity & EncryptoArbitraryLength for openssl-util-test Change-Id: I1ea87b82a8897ee8bfa187715ac1c52883790d24 --- M be/src/runtime/tmp-file-mgr.cc M be/src/util/cpu-info.cc M be/src/util/cpu-info.h M be/src/util/openssl-util-test.cc M be/src/util/openssl-util.cc M be/src/util/openssl-util.h 6 files changed, 176 insertions(+), 37 deletions(-) git pull ssh://gerrit.cloudera.org:29418/Impala-ASF refs/changes/32/9032/4 -- To view, visit http://gerrit.cloudera.org:8080/9032 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: newchange Gerrit-Change-Id: I1ea87b82a8897ee8bfa187715ac1c52883790d24 Gerrit-Change-Number: 9032 Gerrit-PatchSet: 4 Gerrit-Owner: Xianda Ke <[email protected]>
