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			`KPATCH_NAME ?= patch`

kpatch-build: build dynrelas or klp relas depending on kernel version Introduce a second phase in the kpatch-build process that creates kpatch modules or livepatch modules that use the new klp rela sections depending on the kernel version being worked on. This change uses the two new programs to either create a patch module that uses dynrelas (create-kpatch-module) or a patch module that uses klp rela and arch sections + klp symbols marked with the correct Elf flags (create-klp-module). For klp patch modules, the --unique flag for ld is needed to prevent .parainstructions and .altinstructions sections from different objects from being merged, as arch_klp_init_object_loaded() applies these sections per-object. 2017-01-23 20:43:43 +00:00			`LDFLAGS += $(KPATCH_LDFLAGS)`
