+Subject: [PATCH 1/2] pyproject.toml: fix up license information
+
+Without this change, the Python tooling complains that you
+can't have both "license" and "license-files" settings in pyproject.toml.
+
+This issue doesn't happen any more with the Python tooling
+in master (as of August 2025), so it's irrelevant for upstream.

+Subject: [PATCH 2/2] pyproject.toml: relax setuptool version requirement
+
+To match with what's available in Scarthgap
+It turns out that setuptools 69 is sufficient for building this tool.
+The developer may have aligned the version with his testing environment.
+
+This patch is not needed on meta-openembedded master which has a recent enough
+version.

+DESCRIPTION = "\
+    There are plenty of security hardening options for the Linux kernel; Kconfig \
+    options (compile-time); Kernel cmdline arguments (boot-time); Sysctl \
+    parameters (runtime). A lot of them have to be enabled manually to make the \
+    system more secure which is difficult to track. This tool helps with this \
+    task by checking and reporting about the settings compared to a list of \
+    recommendation. \
