Can you please tell me the feasibility of hot patching in an
operating system like linux and if possible please provide me with any details or pointers on that.
I saw in the sun's web site that they have provided hot patching
in their solaris 8. How far it is reliable.
what is hot patching ?
It is nothing but replacing a function present in the memory "on fly".In usual cases suppose
there is a bug in the kernel code, that bug has to be removed and then compiled and linked to get the image [kernel image],which is then booted. Here in hot patching the debuged function has to
be compiled. Then it is linked with the kernel without rebooting the system, on the fly.
I dont know whether this facility is really required for linux. But for any OS developer, this
tool is a required one.
To some extent i succeed in doing a hot patch for a proprietary OS. I wanted to do that
in linux also. Your help is very much needed.
thanks in advance
