*	selftests/exec: Build both static and non-static load_address tests	Kees Cook	2024-06-19	1	-13/+54
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	After commit 4d1cd3b2c5c1 ("tools/testing/selftests/exec: fix link error"), the load address alignment tests tried to build statically. This was silently ignored in some cases. However, after attempting to further fix the build by switching to "-static-pie", the test started failing. This appears to be due to non-PT_INTERP ET_DYN execs ("static PIE") not doing alignment correctly, which remains unfixed[1]. See commit aeb7923733d1 ("revert "fs/binfmt_elf: use PT_LOAD p_align values for static PIE"") for more details. Provide rules to build both static and non-static PIE binaries, improve debug reporting, and perform several test steps instead of a single all-or-nothing test. However, do not actually enable static-pie tests; alignment specification is only supported for ET_DYN with PT_INTERP ("regular PIE").

\| \| \| \| \| \| \| \| \|	Conform the layout, informational and status messages to TAP. No functional change is intended other than the layout of output messages.

*	tools/testing/selftests: add self-test for verifying load alignment	Chris Kennelly	2020-10-16	1	-0/+68
	This produces a PIE binary with a variety of p_align requirements, suitable for verifying that the load address meets that alignment requirement.
