Version: 6.12.19-1
Severity: wishlist
X-Debbugs-Cc: alexandre.ferri...@orange.com
Dear Maintainer,
Since kernel 6.4, the ftrace subsystem has had a "superpower" feature called
funcgraph-retval:
To the existing function graph tracer, it adds the return values. This is a
lifesaver in
complex investigations, as it allows to instantly see the whole chain of "error
returns"
from deep inside an offending call. Without it, doing the same requires
painstakingly enabling
kretprobes on many functions, which obviously adds a huge amount of noise, as
these probes will
also fire outside of the graph of interest. It literally means _days_ instead
of mere minutes !
Problem is, the feature is controlled by CONFIG_FUNCTION_GRAPH_RETVAL, which is
*not*
enabled on Debian kernels. Sure enough, it incurs a slight overhead, but please
note:
- the CPU overhead is only present if runtime-activated (echo 1 >
options/funcgraph-retval)
- the memory overhead is always present, but only on the function-graph
tracer, which is heavyweigth anyway
- it has absolutely no effect outside of ftrace of course
Ftrace is already a Swiss Army Knife, in that it is available on all Debian
production kernels (thanks for that !)
So, it would seem natural to follow its evolution, and integrate such a killer
new feature.
This is low hanging fruit to save precious hours to whoever wants to dig into
the kernel,
or even just troubleshoot some misconfigured sysctl. This ends up avoiding
reports to the Debian BTS :)
What do you think ? Would you consider adding this to the production config ?
CONFIG_FUNCTION_GRAPH_RETVAL=y
Thanks in advance,
-Alex
