Title:
Kprobe event argument syntax in ftrace from ubuntu_kernel_selftests
failed on B PowerPC
Status in ubuntu-kernel-tests:
Fix Released
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Xenial:
Fix Released
Status in linux source package in Bionic:
Fix Released
Bug description:
== Justification ==
When running the ftrace in ubunut_kernel_selftests, the "Kprobe event argument syntax" will fail on Bionic PowerPC.
This is because PowerPC was not supported by this test.
== Fix ==
9855c462 (selftests/ftrace: Add ppc support for kprobe args tests)
This patch can be cherry-picked for Bionic and Xenial.
Although we don't run this ftrace test in Xenial, it will still be a plus to fix this.
It's already been applied in C/D.
== Test ==
Patch tested with Bionic P8. Test passed as expected:
[23] Kprobe event argument syntax [PASS]
== Regression potential ==
None.
This patch is just for the kernel testing tool.
