We've recently attempted to build a universal library capturing every error report, but then were pointed to tracefs, which was just enough for our purpose (https://lkml.org/lkml/2021/1/15/609). Greg also stated that procfs is a bad place for storing reports: https://lkml.org/lkml/2021/1/15/929. Maninder, which exactly problem are you trying to solve? Note that KASAN already triggers a trace_error_report_end tracepoint on every error report: https://elixir.bootlin.com/linux/v5.12-rc8/source/mm/kasan/report.c#L90 Would it help if you used that one? It could probably be extended with more parameters. Another option if you want verbatim reports is to use the console tracepoints, as this is done in https://elixir.bootlin.com/linux/v5.12-rc8/source/mm/kfence/kfence_test.c Note that there are many caveats with error report collection (see the links above), but for testing purpose it might be enough.
