proper makefile support - setup the makefiles to support "make" and "make install", which builds the kpatch-build tools and installs everything in /usr/local. - update kpatch-build to support new paths - add "kpatch build" wrapper around kpatch-build 2014-02-13 16:04:35 +00:00			`include ../Makefile.inc`
first pass at a decent user interface This makes it somewhat easy to use. From the root git dir, just: sudo scripts/kpatch-build ~/foo.patch and it'll take care of everything, eventually spitting out the base module (kpatch.ko) and the hotpatch module kpatch-foo.ko. This is still all very crude, but a better user interface is coming soon. 2014-02-13 03:53:05 +00:00
kmod/core: update API and use hash table My apologies for the size of this commit. I combined these two features (updating API and using a hash table) into a single commit because their implementations are tightly coupled and I didn't want to have to add support for the old kpatch_funcs array with the new API just for the sake of splitting up the commit :-) - Update the core module API to get a more clear separation between core module and patch module. This is cleaner and will help our case for getting the core module merged upstream into the kernel. - Convert the old kpatch_funcs array into a hash table. This is so much nicer performance-wise and everything-else-wise than that ugly old array. - Do the incremental patching in stop machine. This ensures that the funcs hash is up to date and we don't miss anything. - Disable preemption in the ftrace handler when accessing the func hash. That way we don't get conflicts with the stop_machine handler updating the hash. 2014-03-14 21:41:00 +00:00			`CFLAGS += -I../kmod/patch -Wall -g`

make kpatch-build a first class script kpatch-build is outgrowing the kpatch script and probably is a better fit as its own utility instead of being wrapped by kpatch. Install kpatch-build into /usr/local/bin, remove the kpatch wrapper around it, and update the README accordingly. 2014-03-10 14:24:40 +00:00			`$(INSTALL) $(TARGETS) $(LIBEXECDIR)`
