Subject: [PATCH v2 0/7] objtool/klp: sympos/module/alternative/etc fixes
Date: Wed,  5 Aug 2026 07:29:37 -0700	[thread overview]
Message-ID: <cover.1785939903.git.jpoimboe@kernel.org> (raw)

v2: 
- rebased on tip/master (first 6 patches were merged)
- dropped original patches 7-8 (will post followup)
- added .klp.symid fix

v1: https://lore.kernel.org/cover.1785727106.git.jpoimboe@kernel.org

This consolidates fixes for the klp-build issues reported by Joe over
the last several weeks, plus some more things I found while
testing/reviewing.

Fun stuff like symbol resolution, module dependencies, alternatives.

Joe Lawrence (1):
  objtool/klp: Allow new references to module exports

Josh Poimboeuf (6):
  objtool/klp: Fix vmlinux .klp.symid link error for .no_trim_symbol
    symbols
  objtool/klp: Fix size of empty special section entries
  objtool/klp: Ignore replacement offset of empty x86 alternatives
  objtool/klp: Explicitly disallow patching or referencing init
    code/data
  objtool/klp: Fix cross-module klp relocation section naming
  objtool/klp: Don't match local symbols against exports
