kiall - segmentation fault - AT_NULL terminator not found, cannot parse auxv structure about linuxki HOT 3 CLOSED

The systemd-coredump messages may be from something else. There is no "auxv" structure in the kiinfo code. For the kiinfo segfault, it would help to have the ki_all.*.tgz files and I should be able to replicate the data. I'll email you separately.

The coredump was due to several of the per-cpu ki.bin files getting truncated such that a trace record was partially logged and the trace file ended. This is very unusual as there were no error logged and I haven't been able to duplicate the issue.

However, I have modified kiinfo to detect end of the file in the middle of a trace event so that all the trace events up to that point will be processed. For example, in this case, there was still 18.5 seconds of good data and 45M trace events that were processed.

Kiinfo will print the following error when the issue is detected:

Warning: Truncated KI binary detected for cpu 2
Proceeding as if end of trace collection was found

This will be fixed in the 7.8 version.

Fixed in version 7.8, released on Nov 9, 2023.
