Fedora Update Notification

--------------------------------------------------------------------------------
Name : retsnoop
Product : Fedora 36
Version : 0.9.5
Release : 1.fc36
URL :
https://github.com/anakryiko/retsnoop
Summary : A tool for investigating kernel error call stacks
Description :
retsnoop is BPF-based tool that is meant to help debugging kernel issues. It
allows to capture call stacks of kernel functions that return errors (NULL or
-Exxx) and emits every such detected call stack, along with the captured
results.
--------------------------------------------------------------------------------
Update Information:
Massive improvements in how retsnoop determines whether kprobes are attachable:
- add `--debug multi-kprobe` mode to bisect failing multi-kprobe attachment; it
quickly narrows down and logs which kprobes were attempted but failed to be
attached; - skip attaching to kernel functions that have non-unique name and
some of instances are not traceable; - resolve internal mix up of function and
data ksyms; - internal fixes to consistently take into account kernel module to
which ksym/kprobe belongs to. Overall, these fixes and improvements make
retsnoop's mass-attach behavior more reliable.
