08:35 <modem> drsmith i am quite chilly with mailing list

08:35 <modem> but I will try to explain here again, if that's not enough, I will go for the ML

08:35 <modem> SO I am adding a CLI so systemtap

08:36 <modem> This is not a CLI to systemtap itself, it is a CLI that allow some kernel operations at runtime locally

08:36 <modem> while the CLI is python backed, every call are on behalf of some kind of RPC

08:37 <modem> the RPC engine is loaded into the kernel from a .stp exposing a probe procfs

08:37 <modem> Why am I doing that on top of systemtap ? For two main resean : first I want to benefit from the stability of systemtap across a very large number of kernel version

08:38 <modem> secondly, while sometime i need to embed C code, I am doing my best to do everything in .stap source format

08:38 <modem> to keep using portability, and simplicity of course

08:39 <modem> In my CLI I have some hexdump'ing or function/symbol inspection. Either I am sending the string name to the procfs stap kernel probe, and my .stap script need to figure its location

08:39 <modem> or either if that is not possible, I need to feed the symbol name to another layer of the systemtap engine

08:40 <modem> Because I think this is not possible to recover all the vmlinux's symbol from inside a kernel module, while systemtap is pretty efficient at discovering/guessing location of vmlinux on a wide variety of kernel/distrib, i wish to benefit from this ability

08:41 <modem> Now I am willing to contribute some code if needed to add a layer in systemtap, but some advices would be welcomed. Thanks :)

08:41 <modem> If that is not good enough yet i will rewrite this to the ML

08:41 <modem> btw, this is a pro project, ending in 10days, will be opensourced and published. The name is "kernsh v3", it existed previously in v1 in 2003 and then in v2 in ERESI framework around 2005

08:42 <modem> I was the original author of kernsh and reliving it

21:11 <fche> modem, debuginfo is not available to stap at run time

21:11 <fche> -some- symbol-table info may be (as used by symname() type lookup functions)
