Project News: DTrace
2016.10.17: DTrace userspace 0.5.3, kernel modules 0.5.3, libdtrace-ctf 0.5.0
All RPMs are available on the Unbreakable Linux Network.
Bugfixes in dtrace-utils 0.5.3:
- When dtrace(1) exited at the same instant as a process it had grabbed (e.g.
for ustack()) terminated, it could deadlock or crash with an assertion
failure or a segmentation fault.
New features in dtrace-modules 0.5.3:
- It is now possible to have perf-events presented as DTrace SDT probes.
This feature is turned on by default in the kernel. The probes will
appear with the same names as the perf-events and are grouped under the
new 'perf' SDT provider.
In its current implementation, the perf-events DTrace probes do not offer
argument type informtation as is seen with standard DTrace SDT probes.
Bugfixes in dtrace-modules 0.5.3:
- On sparc64, it was possible to crash the system by unloading and reloading
the sdt DTrace multi-provider module due to the handling of memory that is
set aside for SDT probe trampolines. This bug has been fixed.
