Or did you fix the issue since v36? v37 and v38 has an API change that is reverted in v39: https://lore.kernel.org/linux-sgx/20200921195822.GA58176@xxxxxxxxxxxxxxx/ I'm not sure of the root cause yet but you asked to try to out a newer patch set and v39-rc1 is the best option. There was off-by-one error in enclave maximum size calculation fixed in v37 (it was actually a bug in SDM inherited to the code) but that should not result the situation you just described. /Jarkko
