[ Fix ]
Enable arm64 backporting the following patch from upstream:
-
https://github.com/falcosecurity/libs/commit/c4f096099bf81966803d26c40c6c2cb2b8d08033
[ Test Plan ]
Install and load sysdig driver on both Jammy generic and Jammy hwe on
arm64:
$ sudo apt install sysdig-dkms
$ dkms status
$ sudo modprobe sysdig-probe
$ lsmod | grep sysdig
[ Regression potential ]
We may experience regressions in systems that are using sysdig in Jammy.
In particular the sysdig kernel module may fail to load, or eBPF may not be
able to hook functions in kernel space to trace them properly.
[ Other Info ]
Up to version 0.27.1 (packaged in Jammy) the sysdig package included
both a user-space component and a kernel-space component.
The upstream commit 9cedb69555cc96 (build: switch to falcosecurity-libs
external project) decoupled the user-space component and the kernel-space
component in two different packages:
- user-space -> sysdig
- kernel-space -> falcosecurity-libs
(https://launchpad.net/ubuntu/+source/falcosecurity-libs)
Therefore the versions of sysdig greater than 0.28.0 do not suffer from
this FTBFS bug.
On the other hand, since this decoupling happened after Jammy was
released and before Noble was released, only Noble and later series ship
- falcosecurity-libs. On Noble and later series there is no FTFBS bug at
- all.
+ falcosecurity-libs. On Noble and later series both sysdig (user-space)
+ and falcosecurity-libs (kernel-space) compile on all targeted
+ architectures.
