Hi Everybody,
This series consists out of outstanding SGX selftests changes, rebased
and gathered in a single series that is more easily merged for testing
and development, and a few more changes added to expand the existing tests.
The outstanding SGX selftest changes included in this series that have already
been submitted separately are:
* An almost two year old patch fixing a benign linker warning that is still
present today:
https://lore.kernel.org/linux-sgx/20191017030340.18301-2-sean.j.christopher…
The original patch is added intact and not all email addresses
within are valid.
* Latest (v4) of Jarkko Sakkinen's series to add an oversubscription test:
https://lore.kernel.org/linux-sgx/20210809093127.76264-1-jarkko@kernel.org/
* Latest (v2) of Jarkko Sakkinen's patch that provides provide per-op
parameter structs for the test enclave:
https://lore.kernel.org/linux-sgx/20210812224645.90280-1-jarkko@kernel.org/
The reason why most of these patches are outstanding is that they depend
on a kernel change that is still under discussion. Decision to wait in:
https://lore.kernel.org/linux-sgx/f8674dac5579a8a424de1565f7ffa2b5bf2f8e36.…
The original patch for this kernel dependency continues to be included in
this series as a placeholder until the ongoing discussions are concluded.
The new changes introduced in this series builds on Jarkko's outstanding
SGX selftest changes and adds new tests for page permissions, exception
handling, and thread entry.

2.25.1
From: Steven Rostedt (VMware) <rostedt(a)goodmis.org>
commit 210f9df02611cbe641ced3239122b270fd907d86 upstream.
The selftest for ftrace checks some features by checking if the README has
text that states the feature is supported by that kernel. Unfortunately,
this check gives false positives because it many not be checked if there's
spaces in the string to check. This is due to the compare between the
required variable with the ":README" string stripped, because neither has
quotes around them.

The XSAVE feature set supports the saving and restoring of state components,
which is used for process context switching. The state components include
x87 state for FPU execution environment, SSE state, AVX state and so on. In
order to ensure that XSAVE works correctly, add XSAVE basic test for
XSAVE architecture functionality.
This patch set tests and verifies the basic functions of XSAVE/XRSTOR in
user space; during and after signal processing on the x86 platform, the
XSAVE contents of the process should not be changed.
This series introduces only the most basic XSAVE tests. In the
future, the intention is to continue expanding the scope of
these selftests to include more kernel XSAVE-related functionality
and XSAVE-managed features like AMX and shadow stacks.
========
- Change from v3 to v4:
- Improve the comment in patch 1.
- Change from v2 to v3:
- Improve the description of patch 2 git log.
- Change from v1 to v2:
- Improve the cover-letter. (Dave Hansen)
