A full 256M segment is either Exec or NoExec. # The module area is in an Exec segment while vmalloc area is # in a NoExec segment. # # In order to protect module data against execution, select # ARCH_WANTS_MODULES_DATA_IN_VMALLOC. # # For the 8xx (and possibly other 32 bits platform in the future), # there is no such constraint on Exec/NoExec protection, however # there is a critical distance between kernel functions and callers # that needs to remain below 32Mbytes in order to avoid costly # trampolines. By allocating data outside of module area, we # increase the chance for module text to remain within acceptable # distance from kernel core text. # # So select ARCH_WANTS_MODULES_DATA_IN_VMALLOC for 8xx as well. # # Signed-off-by: Christophe Leroy <christophe.leroy@csgroup.eu> # Cc: Michael Ellerman <mpe@ellerman.id.au> # Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> # Cc: Paul Mackerras <paulus@samba.org> # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 01fa88c6d412d0d8fb9ca29bc5e224433428c5a4 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/chleroy_44x_fsp2_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 44x/fsp2_defconfig # < make -s -j 48 ARCH=powerpc O=/kisskb/build/chleroy_44x_fsp2_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 48 ARCH=powerpc O=/kisskb/build/chleroy_44x_fsp2_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/chleroy_44x_fsp2_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- In file included from /kisskb/src/kernel/module/tree_lookup.c:11:0: /kisskb/src/kernel/module/internal.h:179:13: warning: 'module_enable_nx' defined but not used [-Wunused-function] static void module_enable_nx(const struct module mod) { } ^ /kisskb/src/kernel/module/internal.h:180:13: warning: 'module_enable_ro' defined but not used [-Wunused-function] static void module_enable_ro(const struct module mod, bool after_init) {} ^ /kisskb/src/kernel/module/internal.h:181:12: warning: 'module_enforce_rwx_sections' defined but not used [-Wunused-function] static int module_enforce_rwx_sections(Elf_Ehdr hdr, Elf_Shdr sechdrs, ^ In file included from /kisskb/src/kernel/module/kallsyms.c:12:0: /kisskb/src/kernel/module/internal.h:179:13: warning: 'module_enable_nx' defined but not used [-Wunused-function] static void module_enable_nx(const struct module mod) { } ^ /kisskb/src/kernel/module/internal.h:180:13: warning: 'module_enable_ro' defined but not used [-Wunused-function] static void module_enable_ro(const struct module mod, bool after_init) {} ^ /kisskb/src/kernel/module/internal.h:181:12: warning: 'module_enforce_rwx_sections' defined but not used [-Wunused-function] static int module_enforce_rwx_sections(Elf_Ehdr hdr, Elf_Shdr sechdrs, ^ In file included from /kisskb/src/kernel/module/procfs.c:13:0: /kisskb/src/kernel/module/internal.h:179:13: warning: 'module_enable_nx' defined but not used [-Wunused-function] static void module_enable_nx(const struct module mod) { } ^ /kisskb/src/kernel/module/internal.h:180:13: warning: 'module_enable_ro' defined but not used [-Wunused-function] static void module_enable_ro(const struct module mod, bool after_init) {} ^ /kisskb/src/kernel/module/internal.h:181:12: warning: 'module_enforce_rwx_sections' defined but not used [-Wunused-function] static int module_enforce_rwx_sections(Elf_Ehdr hdr, Elf_Shdr sechdrs, ^ Completed OK # rm -rf /kisskb/build/chleroy_44x_fsp2_defconfig_powerpc-gcc5 # Build took: 0:01:19.936430
