Re: [Dprobes] DProbes

[Richard J M. <ric...@uk...>]

Dprobes needs to intercept breakpoint, single-step, readpage and program
fault handling in the kernel. Hence it needs to be a kernel patch of some
sort. We are minimising the complexity of the patch by using GKHI to
simplify the kernel change.

Having installed dprobes, no futher patching is required to create probes.

Re: "To use DProbes, you need to rebuild the kernel and the dprobes
application."

With loadable modules, why do I have to rebuild the kernel?

Is there some reason a smart program couldn't just examine the currently
running kernel and "insert" the appropriate code? I don't know how I
could convince
a customer to "rebuild a kernel" or to load this specific kernel.

Am I missing something?
