Subject: [PATCH v3 26/28] selftests/sgx: Include the dynamic heap size to the ELRANGE calculation
Date: Wed, 12 Jul 2023 16:02:00 -0700 [thread overview]
Message-ID: <20230712230202.47929-27-haitao.huang@linux.intel.com> (raw)
In-Reply-To: <20230712230202.47929-1-haitao.huang@linux.intel.com>
From: Jarkko Sakkinen <jarkko@kernel.org>
When calculating ELRANGE, i.e. the address range defined for an enclave,
and represented by encl->encl_size, also dynamic memory should be taken
into account. Implement setup_test_encl_dynamic() with dynamic_size
parameter for the dynamic heap size, and use it in 'augment_via_eaccept'
and 'augment' tests.
