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: Ia188a0c5b74e4a22fb30f8c12f65e0469eb75f6b Reviewed-on: http://gerrit.cloudera.org:8080/9238 Reviewed-by: Tim Armstrong <tarmstr...@cloudera.com> Tested-by: Tim Armstrong <tarmstr...@cloudera.com> --- 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, 232 insertions(+), 78 deletions(-) Approvals: Tim Armstrong: Looks good to me, approved; Verified -- To view, visit http://gerrit.cloudera.org:8080/9238 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: merged Gerrit-Change-Id: Ia188a0c5b74e4a22fb30f8c12f65e0469eb75f6b Gerrit-Change-Number: 9238 Gerrit-PatchSet: 3 Gerrit-Owner: Xianda Ke <kexia...@gmail.com> Gerrit-Reviewer: Impala Public Jenkins Gerrit-Reviewer: Tim Armstrong <tarmstr...@cloudera.com> Gerrit-Reviewer: Xianda Ke <kexia...@gmail.com>
