82a1978d - kheaders: use 'tar' instead of 'cpio' for copying files

Wed, 18 Dec 2024 10:37:08 +0000

kheaders: use 'tar' instead of 'cpio' for copying filesThe 'cpio' command is used solely for copying header files to thetemporary directory. However, there is no strong reason to use 'cpio'for this purpose. For example, scripts/package/install-extmod-builduses the 'tar' command to copy files.This commit replaces the use of 'cpio' with 'tar' because 'tar' isalready used in this script to generate kheaders_data.tar.xz anyway.Performance-wide, there is no significant difference between 'cpio'and 'tar'.[Before] $ rm -fr kheaders; mkdir kheaders $ time sh -c ' for f in include arch/x86/include do find "$f" -name "*.h" done | cpio --quiet -pd kheaders ' real 0m0.148s user 0m0.021s sys 0m0.140s[After] $ rm -fr kheaders; mkdir kheaders $ time sh -c ' for f in include arch/x86/include do find "$f" -name "*.h" done | tar -c -f - -T - | tar -xf - -C kheaders ' real 0m0.098s user 0m0.024s sys 0m0.131sRevert commit 69ef0920bdd3 ("Docs: Add cpio requirement to changes.rst")because 'cpio' is not used anywhere else during the kernel build.Please note that the built-in initramfs is created by the in-tree tool,usr/gen_init_cpio, so it does not rely on the external 'cpio' commandat all.Remove 'cpio' from the package build dependencies as well.Signed-off-by: Masahiro Yamada List of files: /linux-6.15/scripts/package/mkdebian

kbuild: deb-pkg: remove support for "name " form for DEBEMAILCommit d5940c60e057 ("kbuild: deb-pkg improve maintainer addressgeneration") supported the "name " form for DEBEMAIL, withbehavior slightly different from devscripts.In Kbuild, if DEBEMAIL is given in the form "name ", it is usedas-is, and DEBFULLNAME is ignored.In contrast, debchange takes the name from DEBFULLNAME (or NAME) if set,as described in 'man debchange': If this variable has the form "name ", then the maintainer name will also be taken from here if neither DEBFULLNAME nor NAME is set.This commit removes support for the "name form for DEBEMAIL,as the current behavior is already different from debchange, and theDebian manual suggests setting the email address and name separately inDEBEMAIL and DEBFULLNAME. [1]If there are any complaints about this removal, we can re-add it,with better alignment with the debchange implementation.

kbuild: deb-pkg: hard-code Build-DependsThe condition to require libelf-dev:native is stale because objtool isnow enabled by CONFIG_OBJTOOL instead of CONFIG_UNWINDER_ORC. Not onlyobjtool but also resolve_btfids requires libelf-dev:native; therefore,CONFIG_DEBUG_INFO_BTF should be checked as well.Similarly, CONFIG_SYSTEM_TRUSTED_KEYRING is not the only case thatrequires libssl-dev:native.Perhaps, the following code would provide better coverage, but it ishard to maintain (and may still be imperfect). if is_enabled CONFIG_OBJTOOL || is_enabled CONFIG_DEBUG_INFO_BTF; then build_depends="${build_depends}, libelf-dev:native" fi if is_enabled CONFIG_SYSTEM_TRUSTED_KEYRING || is_enabled CONFIG_SYSTEM_REVOCATION_LIST || is_enabled CONFIG_MODULE_SIG_FORMAT; then build_depends="${build_depends}, libssl-dev:native" fiLet's hard-code the build dependency.Signed-off-by: Masahiro Yamada Reviewed-by: Nicolas Schier List of files: /linux-6.15/scripts/package/mkdebian

4b970e43 - kbuild: deb-pkg: use Debian compliant shebang for debian/rules

Tue, 01 Aug 2023 12:19:25 +0000

kbuild: deb-pkg: use Debian compliant shebang for debian/rulesDebian Policy "4.9. Main building script: debian/rules" requires"debian/rules must start with the line #!/usr/bin/make -f". [1]Currently, Kbuild does not follow this policy.When Kbuild generates debian/rules, "#!$(command -v $MAKE) -f" isexpanded by shell. The resuling string may not be "#!/usr/bin/make -f".There was a reason to opt out the Debian policy.If you run '/path/to/my/custom/make deb-pkg', debian/rules must also beinvoked by the same Make program. If #!/usr/bin/make were hard-coded indebian/rules, the sub-make would be executed by a possibly differentMake version.This is problematic due to the MAKEFLAGS incompatibility, especially thejob server flag. Old Make versions used --jobserver-fds to propagate jobserver file descriptors, but Make >= 4.2 uses --jobserver-auth. The flagdisagreement between the parent/child Makes would result in a processfork explosion.However, having a non-standard path in the shebang causes another issue;the generated source package is not portable as such a path does notexist in other build environments.This commit solves those conflicting demands.Hard-code '#!/usr/bin/make -f' in debian/rules to create a portable andDebian-compliant source package.Pass '--rules-file=$(MAKE) -f debian/rules' when dpkg-buildpackage isinvoked from Makefile so that debian/rules is executed by the same Makeprogram as used to start Kbuild.[1] https://www.debian.org/doc/debian-policy/ch-source.html#main-building-script-debian-rulesSigned-off-by: Masahiro Yamada Tested-by: Nathan Chancellor Reviewed-by: Nicolas Schier List of files: /linux-6.15/scripts/package/mkdebian
