Subject: [Buildroot] [RFC PATCH v3 0/2] Bump sysdig to 0.29.1
Date: Fri, 22 Apr 2022 15:31:32 +0100	[thread overview]
Message-ID: <20220422143134.28561-1-flaniel@linux.microsoft.com> (raw)

Hi.

In this contribution, I bumped sysdig version to 0.29.1.
Indeed, following this discussion [1], Arnout Vandecappelle noted sysdig 0.27.1
cannot be cross-compiled to, e.g., aarch64 because it uses the open() syscall.

To fix this, I bumped sysdig to 0.29.1.
Sadly, some components of sysdig, like libsinsp, libscap and the kernel modules,
were moved to falcosecurity/libs.
So, I added the falcosecurity-libs package.
A new patch was added to sysdig recipe to avoid compiling again
falcosecurity-libs.
Nonetheless, this patch is a bit big, so I prefered to keep the RFC tag to
gather your opinion about it.

I was nonetheless able to build and run sysdig with start-qemu.sh:
Welcome to Buildroot

scap: deallocating consumer (____ptrval____)
scap: no more consumers, stopping capture

So, if you see a particular way to fix the problem I described above or any
problem with this contribution, feel free to share it!

Changes since:
 v2:
  - Add linux CONFIG_ option to execute falcosecurity-libs kernel module.
  - falcosecurity-libs driver name was set so sysdig automatically loads it.

  falcosecurity-libs: add new package
