For example, +instead of something like this: + +struct thing { + ... + union { + struct type1 foo[]; + struct type2 bar[]; + }; +}; + +code works around the compiler with: + +struct thing { + ... + struct type1 foo[0]; + struct type2 bar[]; +}; + +Another case is when a flexible array is wanted as the single member +within a struct (which itself is usually in a union).

This is not something that is supported by the architecture, +but was done anyway to increase compatibility with user space software, +which mostly targeted x86 at the time and did not care about aligned +accesses. + +This feature is one of the remaining impediments to being able to switch +to 64-bit kernels on 64-bit capable hardware running 32-bit user space, +so let's implement it for the arm64 compat layer as well. + +Note that the intent is to implement the exact same handling of +misaligned multi-word loads and stores as the 32-bit kernel does, +including what appears to be missing support for user space programs +that rely on SETEND to switch to a different byte order and back. Also, +like the 32-bit ARM version, we rely on the faulting address reported by +the CPU to infer the memory address, instead of decoding the instruction +fully to obtain this information. + +This implementation is taken from the 32-bit ARM tree, with all pieces +removed that deal with instructions other than LDRD/STRD and LDM/STM, or +that deal with alignment exceptions taken in kernel mode. + +Cc: debian-arm@lists.debian.org +Cc: Vagrant Cascadian <vagrant@debian.org> +Cc: Riku Voipio <riku.voipio@iki.fi> +Cc: Steve McIntyre <steve@einval.com> +Signed-off-by: Ard Biesheuvel <ardb@kernel.org> +Reviewed-by: Arnd Bergmann <arnd@arndb.de> +Link: https://lore.kernel.org/r/20220701135322.3025321-1-ardb@kernel.org +[catalin.marinas@arm.com: change the option to 'default n'] +Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> +--- + arch/arm64/Kconfig | 3 + + arch/arm64/include/asm/exception.h | 1 + + arch/arm64/kernel/Makefile | 1 + + arch/arm64/kernel/compat_alignment.c | 387 +++++++++++++++++++++++++++ + arch/arm64/mm/fault.c | 3 + + 5 files changed, 395 insertions(+) + create mode 100644 arch/arm64/kernel/compat_alignment.c + +--- a/arch/arm64/Kconfig ++++ b/arch/arm64/Kconfig +@@ -1328,6 +1328,9 @@ config THUMB2_COMPAT_VDSO + Compile the compat vDSO with '-mthumb -fomit-frame-pointer' if y, + otherwise with '-marm'. + ++config COMPAT_ALIGNMENT_FIXUPS ++ bool "Fix up misaligned multi-word loads and stores in user space" ++ + menuconfig ARMV8_DEPRECATED + bool "Emulate deprecated/obsolete ARMv8 instructions" + depends on SYSCTL +--- a/arch/arm64/include/asm/exception.h ++++ b/arch/arm64/include/asm/exception.h +@@ -47,6 +47,7 @@ void do_el0_sys(unsigned long esr, struc + void do_sp_pc_abort(unsigned long addr, unsigned int esr, struct pt_regs *regs);
