Hi, to get the most out of the "Source-based livepatch creation tooling" session at this year's LPC Live Patching MC, I'd like to spend as little time as possible on (re-)introducing klp-ccp and the approch behind it, but focus more on discussing open questions. So, to give everybody a chance to get a good overview on past discussions as well as the current state, let me share a few pointers. First of all, there had been Miroslav's talk from last year about compiler optimizations ([1]) and also mine, where I outlined an initial approach to automating source based livepatch creation ([2]). Recordings are available. Meanwhile, the implementation of the proposed tool for copying&pasting live patches together, klp-ccp, has progressed to a state where it can actually be used (*). The sources for klp-ccp have recently been published at ([3]). I've put together a preliminary README describing the overall mode of operation and its interface. The topics I'd like to bring up for discussion are mostly related to integration, so it would be awesome if you could have a brief look. Finally, in case you'd like to get an idea of how the actual output from klp-ccp would look like, you can find the results from three different runs against more or less random function sets at [4], [5] and [6]. Wish you all a save journey and see you next week!
