TestRelroPartial is broken since the last checksec update to 2.7.1 [1]
(Buildroot 2024.08) due to a relro check fix [2] that doesn't work for
powerpc architecture where .got.plt doesn't exist for some reasons
(that's why the expected result "full" is replaced by "Partial").
From [3]:
if ${readelf} -d "${1}/exe" 2> /dev/null | grep -q 'BIND_NOW' || ! ${readelf} -l "${1}/exe" 2> /dev/null | grep -q '\.got\.plt'; then
echo_message '\033[32mFull RELRO \033[m ' 'Full RELRO,' ' relro="full"' '"relro":"full",'
else
echo_message '\033[33mPartial RELRO\033[m ' 'Partial RELRO,' ' relro="partial"' '"relro":"partial",'
checksec tool is problably tested upstream on more common architectures
like x86_64 or aarch64 than powerpc64 e5500. This may explain why
checksec broke on powerpc64 e5500 target.
Also, the Booltin powerpc64-e5500--glibc--stable-2018.02-2 toolchain
used by test_hardening tests was not updated since the hardening tests
were introduced back in 2018.11 release.
So, switch to the current Bootling aarch64 stable toolchain
(currently Bootlin aarch64 glibc stable 2025.08-1).
Checked that all 6 hardening tests pass with this new toolchain:
tests.core.test_hardening.TestFortifyConserv
tests.core.test_hardening.TestFortifyNone
tests.core.test_hardening.TestRelro
tests.core.test_hardening.TestRelroPartial
tests.core.test_hardening.TestSspNone
tests.core.test_hardening.TestSspStrong
