tty: vt: conmakehash: remove non-portable code printing comment header

2024-08-13T09:06:29+00:00

Commit 6e20753da6bc ("tty: vt: conmakehash: cope with abs_srctree no longer in env") included , which invoked another (wrong) patch that tried to address a build error on macOS. According to the specification [1], the correct header to use PATH_MAX is . The minimal fix would be to replace with . However, the following commits seem questionable to me: - 3bd85c6c97b2 ("tty: vt: conmakehash: Don't mention the full path of the input in output") - 6e20753da6bc ("tty: vt: conmakehash: cope with abs_srctree no longer in env") These commits made too many efforts to cope with a comment header in drivers/tty/vt/consolemap_deftbl.c: /* * Do not edit this file; it was automatically generated by * * conmakehash drivers/tty/vt/cp437.uni > [this file] * */ With this commit, the header part of the generate C file will be simplified as follows: /* * Automatically generated file; Do not edit. */ BTW, another series of excessive efforts for a comment header can be seen in the following: - 5ef6dc08cfde ("lib/build_OID_registry: don't mention the full path of the script in output") - 2fe29fe94563 ("lib/build_OID_registry: avoid non-destructive substitution for Perl < 5.13.2 compat") [1]: https://pubs.opengroup.org/onlinepubs/009695399/basedefs/limits.h.html Fixes: 6e20753da6bc ("tty: vt: conmakehash: cope with abs_srctree no longer in env") Cc: stable Reported-by: Daniel Gomez Closes: https://lore.kernel.org/all/20240807-macos-build-support-v1-11-4cd1ded85694@samsung.com/ Signed-off-by: Masahiro Yamada Link: https://lore.kernel.org/r/20240809160853.1269466-1-masahiroy@kernel.org Signed-off-by: Greg Kroah-Hartman

conmakehash uses getenv("abs_srctree") from the environment to strip the absolute path from the generated sources. However since commit e2bad142bb3d ("kbuild: unexport abs_srctree and abs_objtree") this environment variable no longer gets set. Instead use basename() to indicate the used file in a comment of the generated source file.

This change strips $abs_srctree of the input file containing the character mapping table in the generated output. The motivation for this change is Yocto emitting a build warning WARNING: linux-lxatac-6.7-r0 do_package_qa: QA Issue: File /usr/src/debug/linux-lxatac/6.7-r0/drivers/tty/vt/consolemap_deftbl.c in package linux-lxatac-src contains reference to TMPDIR So this change brings us one step closer to make the build result reproducible independent of the build path.

tty: vt: move conmakehash to drivers/tty/vt/ from scripts/

scripts/conmakehash is only used for generating drivers/tty/vt/consolemap_deftbl.c Move it to the related directory. Signed-off-by: Masahiro Yamada Link: https://lore.kernel.org/r/20191217110633.8796-1-masahiroy@kernel.org Signed-off-by: Greg Kroah-Hartman
