RE: [Fault-injection-developer] LKML threads about kprobes

[Zhuang, L. <lou...@in...>]

Hi, Rusty
    We did work based on kprobes. After we investigated kprobes, we found
kprobes had removed GKHI support. So we need to find another way to get
additional control in exception handling... This is a problem we need to
solve in 2.5.x

It looks to me like kprobes will make it in the kernel.  Why don't we work
under that assumption for now.

Humm... kprobes in 2.5.x removed GKHI(General Kernel Hook Interface)
mechanism, which FITH needed. But all kprobes patch in 2.5.x is useful for
FITH, such as do_int3/do_debug interrupt gate. We need a mederate patch to
hook these exception for FITH. But I wonder if this can be accepted by LKML.
Any comments
