3 years ago Intel just released v2.12. The main noteworthy feature is that now Ubuntu 20.04 is also supported. Nothing else noteworthy which should push to upgrade. In some quick tests, make for flow-refactoring works with a 2.12 machine; running make on cr2.0.0 will fail when running the test in demo/chaincode/fpc, but that seems to be an issue which also happens with earlier sgx versions.
A few caveats:
apt update-- which (semi-)automagically upgrades to the latest sgx packages -- can result in a broken upgrade, a simpleapt --fix-broken installdoes provide remedy, though.- it seems on FLC-enabled NUCs, you now need the dcap driver (now as version
1.36.2), the old-style driver, (now as version2.11) does not seem to work anymore. Note, though, that download site provides both. - there is also a newer version of sgxssl (
lin2.11_1.1.1.gvs currently usedlin2.10_1.1.1.g). Nothing important for us to upgrade; in fact right now upgrade wouldn't work as some pthread stuff changed which make pdo crypto fail on that version. - regarding 20.04, a quick fix (PR #463, matching a similar change for PDO) makes all our docker images build, just do
DOCKER_BUILD_OPTS="--build-arg SGX=2.12 --build-arg UBUNTU_VERSION=20.04 --build-arg UBUNTU_NAME=focal" make -C utils/docker.
