linux-toradex.git/tools/objtool/tests/generic/test-klp-funcs-content.sh, branch master Linux kernel for Apalis and Colibri modules objtool/klp: Add test for the contents of the klp_funcs list 2026-09-21T09:12:06+00:00 Song Liu song@kernel.org 2026-09-16T18:43:24+00:00 35021df3834e0b51dd77e4be6ee7cbe9bcfa4825 The patch list is what livepatch acts on, and asserting only that it exists does not say it is right. A function that should have been patched and is missing leaves the bug in place; one that should not be there patches code nobody changed. The fixture changes two of three functions and asserts on all three: the two by name, and the third by its absence. It checks the strings in .rodata.klp.str1.1 as well as the relocations, since the names the kernel matches on are real strings.

The patch list is what livepatch acts on, and asserting only that it exists
does not say it is right.  A function that should have been patched and is
missing leaves the bug in place; one that should not be there patches code
nobody changed.

The fixture changes two of three functions and asserts on all three: the
two by name, and the third by its absence.  It checks the strings in
.rodata.klp.str1.1 as well as the relocations, since the names the kernel
matches on are real strings.
