|Prev Next||OpenBSD and Rthreads||Slide #10|
tracing a process should trace all its threads
need to record and (optionally) display the thread id in the ktrace output
always had to use ktrace -di when tracing threaded procs
most of the work was in improving kdump output and fixing unrelated issues
what credentials should be used when writing ktrace output?
what process file-size limit?
thank you to the clever cookie on the FreeBSD project that came up with dumping of structure by ktrace
very useful for debugging
