The recent commit 6910d7d3867a ("selftests/bpf: Ensure bpf_helper_defs.h are taken from selftests dir") broke compilation against libbpf if it is installed on the system, and $INCLUDEDIR/bpf is not in the include path.
Since having the bpf/ subdir of $INCLUDEDIR in the include path has never been a requirement for building against libbpf before, this needs to be fixed. One option is to just revert the offending commit and figure out a different way to achieve what it aims for. However, this series takes a different approach: Changing all in-tree users of libbpf to consistently use a bpf/ prefix in #include directives for header files from libbpf.
This turns out to be a somewhat invasive change in the number of files touched; however, the actual changes to files are fairly trivial (most of them are simply made with 'sed'). Also, this approach has the advantage that it makes external and internal users consistent with each other, and ensures no future changes breaks things in the same way as the commit referenced above.
The series is split to make the change for one tool subdir at a time, while trying not to break the build along the way. It is structured like this:
- Patch 1-2: Trivial fixes to Makefiles for issues I discovered while changing the include paths.
- Patch 3-7: Change the include directives to use the bpf/ prefix, and updates Makefiles to make sure tools/lib/ is part of the include path, but without removing tools/lib/bpf
- Patch 8: Change the bpf_helpers file in libbpf itself to use the bpf/ prefix when including (the original source of breakage).
- Patch 9-10: Remove tools/lib/bpf from include paths to make sure we don't inadvertently re-introduce includes without the bpf/ prefix.

The 'clean' rule in the samples/bpf Makefile tries to remove backup files (ending in ~). However, if no such files exist, it will instead try to remove the user's home directory. While the attempt is mostly harmless, it does lead to a somewhat scary warning like this:
rm: cannot remove '~': Is a directory
Fix this by using find instead of shell expansion to locate any actual backup files that need to be removed.

The runqslower tool refuses to build without a file to read vmlinux BTF from. The build fails with an error message to override the location by setting the VMLINUX_BTF variable if autodetection fails. However, the Makefile doesn't actually work with that override - the error message is still emitted.
Fix this by only doing auto-detection if no override is set. And while we're at it, also look for a vmlinux file in the current kernel build dir if none if found on the running kernel.

Do you have example command with VMLINUX_BTF override that didn't work (and what error message was emitted)?

I'm planning to mirror runqslower into libbpf Github repo and this ../../../vmlinux piece will be completely out of place in that context. Also it only will help when building kernel in-tree. So I'd rather not add this.

Before this patch:
$ cd ~/build/linux/tools/bpf/runqslower $ make Makefile:18: *** "Can't detect kernel BTF, use VMLINUX_BTF to specify it explicitly". Stop.
$ make VMLINUX_BTF=~/build/linux/vmlinux Makefile:18: *** "Can't detect kernel BTF, use VMLINUX_BTF to specify it explicitly". Stop.
Fix this by only doing auto-detection if no override is set. And while we're at it, also look for a vmlinux file in the current kernel build dir if none if found on the running kernel.

I'm planning to mirror runqslower into libbpf Github repo and this ../../../vmlinux piece will be completely out of place in that context. Also it only will help when building kernel in-tree. So I'd rather not add this.
Well building the kernel in-tree is something people sometimes want to do ;)
Specifically, the selftests depend on this, so we should at least fix those; but I guess it could work to just pass in VMLINUX_BTF as part of the make -C from the selftests dir? I'll try that...

The runqslower tool refuses to build without a file to read vmlinux BTF from. The build fails with an error message to override the location by setting the VMLINUX_BTF variable if autodetection fails. However, the Makefile doesn't actually work with that override - the error message is still emitted.
Do you have example command with VMLINUX_BTF override that didn't work (and what error message was emitted)?
Before this patch:
$ cd ~/build/linux/tools/bpf/runqslower $ make Makefile:18: *** "Can't detect kernel BTF, use VMLINUX_BTF to specify it explicitly". Stop.
$ make VMLINUX_BTF=~/build/linux/vmlinux Makefile:18: *** "Can't detect kernel BTF, use VMLINUX_BTF to specify it explicitly". Stop.
Ok, so this is strange. Try make clean and run with V=1, it might help to debug this. This could happen if ~/build/linux/vmlinux doesn't exist, but I assume you double-checked that. It works for me just fine (Makefile won't do VMLINUX_BTF := assignment, if it's defined through make invocation, so your change should be a no-op in that regard):
$ make clean $ make VMLINUX_BTF=~/linux-build/default/vmlinux V=1 ... .output/sbin/bpftool btf dump file ~/linux-build/default/vmlinux format c > .output/vmlinux.h ...
Wonder what your output looks like?
Fix this by only doing auto-detection if no override is set. And while we're at it, also look for a vmlinux file in the current kernel build dir if none if found on the running kernel.

Yes, it can be handled through VMLINUX_BTF override for selftests. As I said, this will be a self-contained example in libbpf's Github repo, so this "in kernel tree" assumption doesn't stand there.

Take another look at the relevant part of the makefile:
ifneq ("$(wildcard /sys/kernel/btf/vmlinux)","") VMLINUX_BTF := /sys/kernel/btf/vmlinux else ifneq ("$(wildcard /boot/vmlinux-$(KERNEL_REL))","") VMLINUX_BTF := /boot/vmlinux-$(KERNEL_REL) else $(error "Can't detect kernel BTF, use VMLINUX_BTF to specify it explicitly") endif
That if/else doesn't actually consider the value of VMLINUX_BTF; so the override only works if one of the files being considered by the auto-detection actually exists... :)

Fix the runqslower tool to include libbpf header files with the bpf/ prefix, to be consistent with external users of the library. Also ensure that all includes of exported libbpf header files (those that are exported on 'make install' of the library) use bracketed includes instead of quoted.
To not break the build, keep the old include path until everything has been changed to the new one; a subsequent patch will remove that.

From: Toke Høiland-Jørgensen toke@redhat.com
Fix all files in samples/bpf to include libbpf header files with the bpf/ prefix, to be consistent with external users of the library. Also ensure that all includes of exported libbpf header files (those that are exported on 'make install' of the library) use bracketed includes instead of quoted.
To make sure no new files are introduced that doesn't include the bpf/ prefix in its include, remove tools/lib/bpf from the include path entirely, and use tools/lib instead.

I like this change. Maybe the reason so many samples/bpf/ files still included "libbpf.h" was that once-upon-a-time we had a "eBPF mini library" in the file samples/bpf/libbpf.h that were included.
The file was removed/renamed in: https://git.kernel.org/torvalds/c/8d93045077ae

Yes, I think something similar is the case with bpf_helpers.h - that used to be outside libbpf, and I guess no one bothered to do a cleanup such as this one when it was moved...

The change to use angled includes for bpf_helper_defs.h breaks compilation against libbpf when it is installed in the include path, since the file is installed in the bpf/ subdirectory of $INCLUDE_PATH. Fix this by adding the bpf/ prefix to the #include directive.

do we need this? bpftool's makefile will build its own libbpf.a independently. We can probably optimize that, but see above, we need to ensure that we build only within selftest/bpf dirs.
This "read-only outside of selftests/bpf" requirement actually made me realize that we probably need to specify OUTPUT pointing somewhere inside selftests/bpf/tools subdir to build entire bpftool within selftests/bpf directory and not touch anything outside.

This turns out to be a somewhat invasive change in the number of files touched; however, the actual changes to files are fairly trivial (most of them are simply made with 'sed'). Also, this approach has the advantage that it makes external and internal users consistent with each other, and ensures no future changes breaks things in the same way as the commit referenced above.
The series is split to make the change for one tool subdir at a time, while trying not to break the build along the way. It is structured like this:
Patch 1-2: Trivial fixes to Makefiles for issues I discovered while changing the include paths.
Patch 3-7: Change the include directives to use the bpf/ prefix, and updates Makefiles to make sure tools/lib/ is part of the include path, but without removing tools/lib/bpf

Patch 9-10: Remove tools/lib/bpf from include paths to make sure we don't inadvertently re-introduce includes without the bpf/ prefix.
Thanks, Toke, for this clean up! I tested it locally for my set up: runqslower, bpftool, libbpf, and selftests all build fine, so it looks good. My only concern is with selftests/bpf Makefile, we shouldn't build anything outside of selftests/bpf. Let's fix that. Thanks!

Since having the bpf/ subdir of $INCLUDEDIR in the include path has never been a requirement for building against libbpf before, this needs to be fixed. One option is to just revert the offending commit and figure out a different way to achieve what it aims for. However, this series takes a different approach: Changing all in-tree users of libbpf to consistently use a bpf/ prefix in #include directives for header files from libbpf.
I don't think such approach will work in all cases. Consider the user installing libbpf headers into /home/somebody/include/bpf/, passing that path to -I and trying to build bpf progs that do #include "bpf_helpers.h"... In the current shape of libbpf everything will compile fine, but after patch 8 of this series the compiler will not find bpf/bpf_helper_defs.h. So I think we have no choice, but to revert that part of Andrii's patch. Note that doing #include "" for additional library headers is a common practice. There was nothing wrong about #include "bpf_helper_defs.h" in bpf_helpers.h.

OK, I'll take another look at that bit and see if I can get it to work with #include "bpf_helper_defs.h" and still function with the read-only tree (and avoid stale headers).
