Thomas Weißschuh b01c939d58 selinux: add generated av_permissions.h to targets
av_permissions.h was not declared as a target and therefore not cleaned
up automatically by kbuild.

Makefile for building the SELinux module as part of the kernel tree.

NOTE: There are a number of improvements that can be made to this Makefile

once the kernel requires make v4.3 or greater; the most important feature

lacking in older versions of make is support for grouped targets. These

improvements are noted inline in the Makefile below ...

obj-$(CONFIG_SECURITY_SELINUX) := selinux.o

ccflags-y := -I$(srctree)/security/selinux -I$(srctree)/security/selinux/include

ccflags-$(CONFIG_SECURITY_SELINUX_DEBUG) += -DDEBUG

selinux-y := avc.o hooks.o selinuxfs.o netlink.o nlmsgtab.o netif.o
netnode.o netport.o status.o
ss/ebitmap.o ss/hashtab.o ss/symtab.o ss/sidtab.o ss/avtab.o
ss/policydb.o ss/services.o ss/conditional.o ss/mls.o ss/context.o

selinux-$(CONFIG_SECURITY_NETWORK_XFRM) += xfrm.o selinux-$(CONFIG_NETLABEL) += netlabel.o selinux-$(CONFIG_SECURITY_INFINIBAND) += ibpkey.o selinux-$(CONFIG_IMA) += ima.o

genhdrs := flask.h av_permissions.h

see the note above, replace the dependency rule with the one below:

$(addprefix $(obj)/,$(selinux-y)): $(addprefix $(obj)/,$(genhdrs))

$(addprefix $(obj)/,$(selinux-y)): $(obj)/flask.h

quiet_cmd_genhdrs = GEN $(addprefix $(obj)/,$(genhdrs)) cmd_genhdrs = $< $(addprefix $(obj)/,$(genhdrs))

targets += $(genhdrs)

see the note above, replace the 'flask.h' rule with the line below:

$(addprefix $(obj)/,$(genhdrs)) &: $(obj)/genheaders FORCE

$(obj)/flask.h: $(obj)/genheaders FORCE $(call if_changed,genhdrs)

hostprogs := genheaders HOST_EXTRACFLAGS += -I$(srctree)/security/selinux/include
