v4:
- Rebased on 9a73f085dc91 (tip/objtool/urgent)
- Dropped elf_add_data() fix, added __clone_symbol() align fix [Josh]
- Adopted Josh's kernel version fix [Josh]
- Updated friendly msg, "foo.patch: unsupported patch to bar.c" [Josh]
- s/warn:/warning:/, trap_err -> die, and commit msg clarification on
colorization commit [Josh]
- Use "fuzz" instead of "drift", adjust output ordering, and send patch
cmd errors to stderr [Josh]
- Dropped ("livepatch/klp-build: don't look for changed objects in
tools/") for now
- Added Song's Acks [Song]
v3:
https://lore.kernel.org/live-patching/[email protected]/T/#t
- Added a patch to objtool ELF code to fix packed string section alignment
- Simplified the mkstemp() patch and surrounding code [Josh]
- Added patches to catch grep use, add Makefile shellcheck, and fix
current shellcheck warnings [Josh]
- Simplified the short-circuit validation patch [Josh]
- Added a patch to fix short-circuit version mismatch
- Pretty-print output in color [Josh]
- Reduce 'patch' chatter to fuzz/offset warning during patch validation
- Prune tools/ from paths that find_objects() looks for changed objects
v2:
https://lore.kernel.org/live-patching/[email protected]/
- Update patch subject prefixes accordingly [Josh]
- Added a small objtool/klp patch. Test systems setup crazy long
pathnames :D
- Removed patch ("limit parent .git directory search") as this version
replaces the use of git apply --recount with patch and recountdiff.
A side effect of this simplification was no longer needing this weird
hack. [Josh]
- Updated the patch that handles input patches that add files to also
support removing files, implement this by directly inspecting the
.patch +++ and --- header lines via two file lists [Josh]
- Implement two short-circuiting updates: validate patches for steps 1
and 2, and allow the user to omit patches for steps 3 and 4. This
combines the original 'fail-fast' patch and some related notes on the
v1 thread. [Josh]
- Since v2 replaces git apply with patch and recountdiff, there is no
need for a -z/--fuzz argument, it comes with GNU patch for free.
