Subject: [RFC PATCH v2.1 25/30] selftests/sgx: Test complete changing of page type flow
Date: Fri, 4 Mar 2022 11:35:19 +0200 [thread overview]
Message-ID: <20220304093524.397485-25-jarkko@kernel.org> (raw)
In-Reply-To: <20220304093524.397485-1-jarkko@kernel.org>
From: Reinette Chatre <reinette.chatre@intel.com>
Support for changing an enclave page's type enables an initialized
enclave to be expanded with support for more threads by changing the
type of a regular enclave page to that of a Thread Control Structure
(TCS). Additionally, being able to change a TCS or regular enclave
page's type to be trimmed (SGX_PAGE_TYPE_TRIM) initiates the removal
of the page from the enclave.
Test changing page type to TCS as well as page removal flows
in two phases: In the first phase support for a new thread is
dynamically added to an initialized enclave and in the second phase
the pages associated with the new thread are removed from the enclave.
As an additional sanity check after the second phase the page used as
a TCS page during the first phase is added back as a regular page and
ensured that it can be written to (which is not possible if it was a
TCS page).
