Limitations
General
-
Warp v3.0 (and products based on this including Warp Server v4.0) MUST
be at least Fixpak 16 (XR_W016). This was the Fixpak in which IBM
introduced the Security Enabling Services (SES) tracepoints.
-
At any one time, only a single device driver can "hook" OS/2's SES tracepoints.
Since a driver must register for these tracepoints at IPL time and it cannot
relinquish these tracepoints, there is no way to share access to this "resource".
This means that Installable Security System (ISS) modules and other tools
(e.g. FWATCH) that rely upon these tracepoints cannot operate at the same
time as KTRACE.
-
Only one instance of KTRACE can be installed at a time.
-
Timestamps have a maximum resolution of 8ms. This means that each
actual event is guaranteed to have occurred within 8 milliseconds of the
recorded timestamp, but more granular timing currently is not available.
