Subject: [PATCHES 0/4] More perf.data header validation
Date: Tue, 14 Apr 2026 17:48:43 -0300 [thread overview]
Message-ID: <20260414204847.293557-1-acme@kernel.org> (raw)
Hi,
This is picking up from what was reported in the previous
series, pre-existing lack of perf.data file validation, processing files
and buffers in header.c in a similar fashion.
There is more to process in the trace data, but that is a
different can of worms that needs to be dealt with in a similar,
upcoming patch series,
This is probably 7.2 material, but if feeling this can still
sneak into 7.1, feel free to do it :-)
Now lets see what Sashiko discovers while I still don't have it
running locally right after Claude, before submitting it publicly, which
will soon happen :-)
