5f52d47c - bpf/preload: Clean up .gitignore and "clean-files" target

Wed, 20 Oct 2021 09:46:47 +0000

bpf/preload: Clean up .gitignore and "clean-files" targetkernel/bpf/preload/Makefile was recently updated to have it installlibbpf's headers locally instead of pulling them from tools/lib/bpf. Buttwo items still need to be addressed.First, the local .gitignore file was not adjusted to ignore the filesgenerated in the new kernel/bpf/preload/libbpf output directory.Second, the "clean-files" target is now incorrect. The old artefactsnames were not removed from the target, while the new ones were addedincorrectly. This is because "clean-files" expects names relative to$(obj), but we passed the absolute path instead. This results in theoutput and header-destination directories for libbpf (and theircontents) not being removed from kernel/bpf/preload on "make clean" fromthe root of the repository.This commit fixes both issues. Note that $(userprogs) needs not be addedto "clean-files", because the cleaning infrastructure already accountsfor it.Cleaning the files properly also prevents make from printing thefollowing message, for builds coming after a "make clean":"make[4]: Nothing to be done for 'install_headers'."v2: Simplify the "clean-files" target.Fixes: bf60791741d4 ("bpf: preload: Install libbpf headers when building")Signed-off-by: Quentin Monnet Signed-off-by: Andrii Nakryiko Acked-by: John Fastabend Link: https://lore.kernel.org/bpf/20211020094647.15564-1-quentin@isovalent.com List of files: /linux-6.15/kernel/bpf/preload/.gitignore

bpf/preload: Make sure Makefile cleans up after itself, and add .gitignoreThe Makefile in bpf/preload builds a local copy of libbpf, but does notproperly clean up after itself. This can lead to subsequent compilationfailures, since the feature detection cache is kept around which can leadsubsequent detection to fail.Fix this by properly setting clean-files, and while we're at it, also add a.gitignore for the directory to ignore the build artifacts.Fixes: d71fa5c9763c ("bpf: Add kernel module with user mode driver that populates bpffs.")Signed-off-by: Toke Høiland-Jørgensen Signed-off-by: Alexei Starovoitov Link: https://lore.kernel.org/bpf/20200927193005.8459-1-toke@redhat.com List of files: /linux-6.15/kernel/bpf/preload/.gitignore
