>Description:
Regex for grabbing ptrace flags for kdump is not inclusive enough.
Before fix:
CALL ptrace(<invalid=5>, ...)
After fix:
CALL ptrace(PT_WRITE_D, ...)
>How-To-Repeat:
ktrace something that uses ptrace(PT_WRITE_D,...) then use kdump to view results.
>Fix:
apply patch below. It appears that no extraneous garbage is picked up by the modified regex (which just adds '_' is an additional character).
