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

dynrelas support, obsoleting link-vmlinux-syms This adds dynamic linking support for the patch modules. It is the first step toward supporting patching module code and relocatable kernels. Rela entries that reference non-included local and non-exported global symbols are converted to "dynrelas". These dynrelas are relocations that are done by the core module, not the kernel module linker. This allows the core module to apply offsets to the base addresses found in the base vmlinux or module.

improve kpatch-build Makefile Right now, the makefile has one target, create-diff-object, which contains all the source/headers as one long list and all the source files compiled in one command to make create-diff-object. This doesn't scale well and doesn't accurately portray the dependencies of each object that contribute to the final binary. This commit renames create-diff-object.c to main.c so that it can be compiled and linked seperately and cleanly in Make and autogenerates dependencies for each .o. This should make it easier to add additional object files, or refactor the very large main.o into seperate object file, later. 2014-09-23 14:45:04 +00:00			`OBJS = create-diff-object.o lookup.o insn/insn.o insn/inat.o`

restructure building process Right now, we do three build passes: one to build the original tree (full) build, one to build the patch tree (diff build), then one to rebuild original objects that where changed by the patch (diff build). This is going to be a problem when we try to support (near) full tree rebuilds due to changes in commonly included header files. This commit changes the build process to intercept calls to gcc by make using the CROSS_COMPILE environment variable and, during the patched build phase, copies the original object for any object that is about to rebuilt due to a change. This reduces the number of build passes to the minimum possible (two). Signed-off-by: Seth Jennings <sjenning@redhat.com> 2014-08-07 20:33:31 +00:00			`$(INSTALL) $(TARGETS) kpatch-gcc $(LIBEXECDIR)`
make kpatch-build a first class script kpatch-build is outgrowing the kpatch script and probably is a better fit as its own utility instead of being wrapped by kpatch. Install kpatch-build into /usr/local/bin, remove the kpatch wrapper around it, and update the README accordingly. 2014-03-10 14:24:40 +00:00			`$(INSTALL) -d $(BINDIR)`
