[Buildroot] [RFC PATCH 0/4] add BCC and bpftrace packages

[Buildroot] [RFC PATCH 0/4] add BCC and bpftrace packages

[Qais Yousef]

*** RESEND AFTER SUBSCRIBING TO THE LIST ***

The following series adds 2 new packages:

	* BPF Compiler Collection (BCC)
	* bpftrace

It is based on 2020.08 tag. Can rebase on tip of master after this initial RFC
review.

The support was validated on x86_64 and aarch64 (little endian). Hence
restricted to these 2 archs only. aarch64 big endian is set as valid, but when
I tried to compile that I think LLVM or clang support for aarch64_be + BPF was
generating some errors; or something else was missing. So it might be a better
idea to remove BR2_aarch64_be from Config.in dependency.

I tried to enable i386 and arm (aarch32); but I encountered some issues and
decided to narrow the initial support to what I got working in hope that other
archs support can follow through later if people are interested.

IIRC the issues were:

	* bpftrace doesn't support these 2 archs.
	* BCC had some build failures on arm.
	* BCC had runtime issues on i386.

Marking this as RFC as it is something that was done over several weekends and
my last contribution to buildroot was many many years ago. So I am sure there
are many rough edges to tackle. Beside from my vague description above, you
might have gotten the hint it's been a while since I last touched it. But I'd
like to get the support merged, so hopefully starting a discussion with what
I have now is a better start.

  llvm: Add BPF backend
  Add BPF Compiler Collection (BCC) Package
  Add bpftrace package
  clang: Fix undefined reference to dladdr error

There is already a pending patch to review enabling BPF backend in llvm.
http://patchwork.ozlabs.org/project/buildroot/patch/20200824181740.12878-1-jugurtha.belkalem at smile.fr/

Your patch appears to be the same as the one we published with Jugurtha.
You are welcome to review and tests patches available from patchwork, see the
manual: http://nightly.buildroot.org/manual.html#_reviewing_and_testing_patches

The bcc patch series is present in patchwork since a long time due to lack of
review, see the first submission back in January 2019:
http://patchwork.ozlabs.org/project/buildroot/patch/20190113212118.14512-1-romain.naour at gmail.com/

So, Your help to review is really important :)

Best regards,
Romain

Yes sure. I actually picked it up and applied and managed to build it and test
for x86_64 and aach64 (little endian) on qemu. I had to apply the weird fix in
patch 4. And remove the dependency on compiling the kernel in buildroot as
I compile my own kernels. It did work :)

I'll add these comments to the patch once I figure out how I can comment.
I hope I don't have to create a patchwork account for this. Hopefully I can
use the message-id to respond via email.

Thanks

[Buildroot] [RFC PATCH 2/4] Add BPF Compiler Collection (BCC) Package

[Qais Yousef]

BCC is a toolkit for creating efficient kernel tracing and manipulation
programs, and includes several useful tools and examples.

Only tested to work on x86_64 and aarch64.

I had issues getting i386 and aarch32 to work. More archs support can be
added later hopefully after this initial support.

We try to avoid the first person (I) in the commit log.
Maybe such comment can be added bellow the "---" *

Maybe you can compare with the bcc package submitted by Jugurtha

BCC use git as VCS, so we prefer if a patch is generated using git format-patch
command. Doing so, the file will contain all metadata such the commit author,
the commit log etc.

We recommend to try to upstream any patches as much as possible.

What was the issue you get?

Jugurtha noticed some issues with bcc that restrict bcc to glibc based toolchain
only (hadcoded GNU tuple). Also libc.so.6 is used in other places in BCC code.

So, I would suggest to support only glibc for now and report the issue upstream.

Note: musl simply use "libc.so".

Well, the bcc buildsystem is really not cross-compilation friendly...

Indeed bcc can be used with python2 but we planed to remove it from Buildroot in
a near future.

We prefer select clang package and add reverse dependencies to bcc package.

We identified some other dependencies (flex, audit, iperf3, netperf and xz).

I'm not sure about tar dependency. OK to select zlib, it seem we also need
BR2_PACKAGE_PYTHON3_ZLIB for test_uprobes.py.

Here you are mixing host headers and target headers.

What about python-bcc module ? Can you review this part ?

BCC requires the linux kernel sources on the target to build bpf code or a 5.2
kernel with CONFIG_IKHEADERS (among other kernel options).

Sorry the quality is not as I'd like them to be. But this work was something
I was doing on the side and wasn't keeping good track of it. I use buildroot
root as my rootfs while testing and felt like having BCC and bpftrace would be
nice, so started seeing what it takes to add them.

I will improve the quality in the next submission and do things properly.

I do add host-flex dependency on bcc.mk. xz is unnecessary if we use tar (see
below). audit, iperf3 and netperf dependencies do look strange to me. Certainly
I didn't need them.

Let me try to play with that.

As you noted below, now the kernel provides the headers in a tar file. BCC
automatically detect the presence of this file and performs the untarring.
Busybox tar was failing to work, hence adding the dependency on proper tar
package. No need for xz dependency then or any manual handling to extract the
headers.

v0.15.0 was the latest then. Should have checked for an update before posting.

I didn't need to do that. I will remove it and see if one of my patches has
fixed it.

IMHO the instructions to build the kernel shouldn't be coupled with this
package. BCC provides good instructions on how to configure the kernel for BPF
support. And it is a fast moving target. There's now CONFIG_DEBUG_INFO_BTF
which AFAICT removes the need for the headers. Which config is more suitable
should be up to the user to decide.

Besides I build the kernel separately, so forcing the dependency is not
friendly for this class of users :-)

Thanks!

[Buildroot] [RFC PATCH 3/4] Add bpftrace package

[Qais Yousef]

bpftrace is a high-level tracing language for Linux enhanced Berkeley
Packet Filter (eBPF) available in recent Linux kernels (4.x).

Only tested on x86_64 and aarch64. The package doesn't support i386 and
aarch32.

Maybe libparser should be forced to build as a static library by bpftrace and
not installed.

If no library is installed by bpftrace, we can remove this line.

Usually the CMAKE_BUILD_TYPE is handled by the Buildroot package infra.
There are some exceptions like for llvm/clang where the build blowup with  -
-DCMAKE_BUILD_TYPE=Debug...

The bpftrace.hash file is missing, see
http://nightly.buildroot.org/manual.html#adding-packages-hash

I forgot to mention the DEVELOPERS file entry in my previous review:
http://nightly.buildroot.org/manual.html#DEVELOPERS

You need to add you as developer of bpftrace package.
Feel free to add you to other packages such bcc.

Best regards,
Romain

It includes <sys/personality.h>. Maybe because I was building with uClibc first
and it didn't have an updated header. I realized much later when I was getting
weird aarch64 errors that I must switch to glibc for aarch64 at least.

Probably this can be dropped if we depend on glibc all the time.

Hmm okay. Let me see if I can do this in a way that is upstreamable.

Good question.

I think I was seeing failures similar to the one described in the link below.
Something wasn't found in LLVM library without enabling this option. Will try
to reproduce and document it better. Unless you know of a better way to handle
these type of problems :-)

Cool. Thanks for the review! I will work on all of these items and post an
updated series as soon as it's ready.

Please note I am doing this on evenings and weekends only. So please be patient
with me for any delays in responses or following up. It's just me trying to
find the time to work on this. I certainly intend to follow this through :-)

Thanks!

This is the error that I get if I don't enable LLVM_RTTI:

buildroot-arm64/output/host/lib/gcc/aarch64-buildroot-linux-gnu/9.3.0/../../../../aarch64-buildroot-linux-gnu/bin/ld: ast/libast.so: undefined reference to `typeinfo for llvm::SectionMemoryManager'
buildroot-arm64/output/host/lib/gcc/aarch64-buildroot-linux-gnu/9.3.0/../../../../aarch64-buildroot-linux-gnu/bin/ld: ast/libast.so: undefined reference to `typeinfo for llvm::orc::SymbolResolver'
collect2: error: ld returned 1 exit status

I understood after a bit of digging that it has hard dependency on having RTTI
enabled.

Is there a preferred way to solve these type of problems?

Thanks

.. and this were caused by using uClibc. With Glibc I can't reproduce them. So
it's just uClibc lacks the new headers and definitions.

The below define in bpftrace.mk makes this and the other libs static:

	+BPFTRACE_CONF_OPTS += -DBUILD_SHARED_LIBS:BOOL=OFF

There's a weird requirement for bpftrace to work correctly. It must not be
stripped otherwise it'll lose an important functionality. I found the below
bugzilla which describes the problem:

	https://bugzilla.redhat.com/show_bug.cgi?id=1865787

Is there a way to tell buidlroot not to strip a binary without setting it in
the config? I couldn't find an example in .mk file - but maybe I didn't look
hard enough.

Thanks

[Buildroot] [RFC PATCH 4/4] clang: Fix undefined reference to dladdr error

[Qais Yousef]

For some reason the cmake::find_library() can't detect the path to dl,
so we end up not including the right library when linking, hence the
error above.

Could be a hack/workaround to the real problem.

I'm not sure about this patch. Can you describe how to reproduce the issue?

It just complained about not finding the library. Hit the same issue when
building Jugurtha BCC patch. Maybe something wrong in my environment.

Will try to reproduce and copy the full error message.

Full error message buildingn for aarch64.

	/usr/bin/ld: CMakeFiles/libclang.dir/CIndexer.cpp.o: in function `clang::CIndexer::getClangResourcesPath[abi:cxx11]()':
	CIndexer.cpp:(.text._ZN5clang8CIndexer21getClangResourcesPathB5cxx11Ev+0x9b): undefined reference to `dladdr'
	collect2: error: ld returned 1 exit status
	make[4]: *** [tools/libclang/CMakeFiles/libclang.dir/build.make:395: lib/libclang.so.9] Error 1
	make[3]: *** [CMakeFiles/Makefile2:8451: tools/libclang/CMakeFiles/libclang.dir/all] Error 2
	make[3]: *** Waiting for unfinished jobs....

I am building on top of 2020.08 tag (2766f346195dec29b53bc09f6038193998ea3693)
+ Jugurtha's BCC patch + my bpftrace patch + a fixup patch to BCC to allow
building without the kernel dependency.

I attached the defconfig. I think just trying to build host-clang should
reproduce it, assuming it's not happening only for me for some weird reason.

I was based on 2020.05.{1,2} when I first hit this error.

Thanks

I reviewed your RFC series. I'm agree that bcc is difficult to cross-compile...

I suggest adding bpftrace to the bcc series from Jugurtha and keeping you as
author of this package.

@jugurtha can you have a look at bpftrace package ?

I'll mark your RFC series "Changes requested" in patchwork.
Thanks!

Best regards,
Romain

Thanks a lot for your review! I will try to address as much as I can over the
weekend and either post a new series or get back to you with more info.

I did test it and I think using it as a base makes sense. I will try to review
it over the weekend too.
