I'm tasked with reconstructing the CentOS version of the GlibC library for testing with gethostbyname(). My mission is to show that we are not affected by the latest exploit for the product we are shipping targeted for RHEL and CentOS. To do so, I want to equip gethostbyname() with additional code.
I may be way out of line here, haven't had much coffee yet, but I wonder if systemtap could be used to achieve your goals less intrusively?
Already knowing how to build GlibC, I think that may take less of my time than attempting to figure out how to use systemtap. But, you better believe that I'll keep that in mind ::throws in toolbox:: for later. This one I need to be as fast as possible on.
Thanks for the info!
