The traditional ELF loader cannot be -enabled on noMMU systems. - -Commit 5e588114329c ("ARM: start_thread(): don't always clear all regs") -fixed the start_thread() code so that it maintains the required -elf-fdpic registers through to the new process, but it only does that if -current has its personality FDPIC_FUNCPTRS bit set. That is true for -elf-fdpic format binaries but will not be true for non-fdpic ELF -binaries. - -Modify the test of the FDPIC_FUNCPTRS personality bit to also carry out -the register restore if this is a noMMU system. This is not perfect, -since it will also preserve these registers on noMMU systems for all -binary format types (could be flat format for example). That won't break -anything, but it is potentially leaking some information into the new -process. But for the noMMU case we need those start time registers set to -be able to finalize the runtime loading of the -pie style ELF binary -(carry out its segment and dynamic relocation processing). - -Unfortunately the FDPIC_FUNCPTRS flag cannot just be enabled for all -elf-fdpic loaded binaries. That personality bit is used for other things -like the controlling the changed behavior for signal handling. - -There is no change in behavior for normal ELF loading on MMU systems. -A -pie style ELF binary built for noMMU systems can be load and run using -the usual ELF loader on an MMU system (elf-fdpic loader not required in -this case). - -Signed-off-by: Greg Ungerer <gerg@kernel.org> ---- - arch/arm/include/asm/processor.h | 3 ++- - 1 file changed, 2 insertions(+), 1 deletion(-) - -diff --git a/arch/arm/include/asm/processor.h b/arch/arm/include/asm/processor.h -index 326864f79d18..5074cc3ae4e1 100644 ---- a/arch/arm/include/asm/processor.h -+++ b/arch/arm/include/asm/processor.h -@@ -60,7 +60,8 @@ static inline void arch_thread_struct_whitelist(unsigned long *offset, - } \ - memset(regs->uregs, 0, sizeof(regs->uregs)); \ - if (IS_ENABLED(CONFIG_BINFMT_ELF_FDPIC) && \ -- current->personality & FDPIC_FUNCPTRS) { \ -+ ((!

Recent changes to convert the versatile machine -to device tree lost this ability. (Although older kernels could be built -they did not run due to a bug in the IO_ADDRESS() mapping on this machine). - -The motivation for this is that the versatile machine is well supported -in qemu. And this provides an excellent platform for development and -testing no-MMU support on ARM in general. - -This patch adds a versatile platform selection in the upper level arm -system type menu - where it appeared in older kernel versions - when -configuring for the no-MMU case.
