Christoph Hellwig suggested a slightly different path for handling backwards compatibility with the 32-bit time_t based system calls: Rather than simply reusing the compat_sys_* entry points on 32-bit architectures unchanged, we get rid of those entry points and the compat_time types by renaming them to something that makes more sense on 32-bit architectures (which don't have a compat mode otherwise), and then share the entry points under the new name with the 64-bit architectures that use them for implementing the compatibility. The following types and interfaces are renamed here, and moved from linux/compat_time.h to linux/time32.h: old new --- --- compat_time_t old_time32_t struct compat_timeval struct old_timeval32 struct compat_timespec struct old_timespec32 struct compat_itimerspec struct old_itimerspec32 ns_to_compat_timeval() ns_to_old_timeval32() get_compat_itimerspec64() get_old_itimerspec32() put_compat_itimerspec64() put_old_itimerspec32() compat_get_timespec64() get_old_timespec32() compat_put_timespec64() put_old_timespec32() I considered doing this only for those instances that are actually shared between 32-bit and 64-bit kernels, but doing it everywhere avoids duplication. This should make more sense for the 32-bit implementation, and the naming suggests that these interfaces are meant for 'old' syscalls only, and that they always operate on 32-bit time_t on both 32-bit and 64-bit architectures, something that may not be obvious from the compat_* naming. I'm not renaming the timex, rusage and itimerval structures, as we are still debating what the new interface will look like, and whether we will need a replacement at all. This also doesn't change the names of the syscall entry points, which can be done more easily when we actually switch over the 32-bit architectures to use them, at that point we need to change COMPAT_SYSCALL_DEFINEx to SYSCALL_DEFINEx with a new name, e.g. with a _time32 suffix. Suggested-by: Christoph Hellwig <hch@infradead.org> Link: https://lore.kernel.org/lkml/20180705222110.GA5698@infradead.org/ Signed-off-by: Arnd Bergmann <arnd@arndb.de> --- Both Deepa and I have pending syscall conversion patches, but if we can get consensus on the rename, they should be easy to rebase on top of this patch. The patch would be easy to split up in various ways, but since it is a trivial rename, I went for a big patch with the first attempt. --- arch/arm64/include/asm/compat.h | 6 +- arch/arm64/include/asm/stat.h | 2 +- arch/mips/include/asm/compat.h | 6 +- arch/mips/kernel/binfmt_elfn32.c | 14 ++-- arch/mips/kernel/binfmt_elfo32.c | 14 ++-- arch/parisc/include/asm/compat.h | 6 +- arch/powerpc/include/asm/compat.h | 6 +- arch/powerpc/kernel/asm-offsets.c | 8 +-- arch/powerpc/oprofile/backtrace.c | 2 +- arch/sparc/include/asm/compat.h | 6 +- drivers/media/v4l2-core/v4l2-compat-ioctl32.c | 4 +- fs/aio.c | 8 +-- fs/compat_binfmt_elf.c | 2 +- fs/compat_ioctl.c | 6 +- fs/select.c | 20 +++--- fs/timerfd.c | 12 ++-- fs/utimes.c | 12 ++-- fs/xfs/xfs_ioctl32.c | 2 +- fs/xfs/xfs_ioctl32.h | 2 +- include/linux/compat.h | 96 +++++++++++++-------------- include/linux/compat_time.h | 32 --------- include/linux/elfcore-compat.h | 8 +-- include/linux/restart_block.h | 4 +- include/linux/syscalls.h | 2 +- include/linux/time32.h | 25 +++++++ ipc/mqueue.c | 8 +-- ipc/msg.c | 6 +- ipc/sem.c | 10 +-- ipc/shm.c | 6 +- ipc/syscall.c | 2 +- ipc/util.h | 2 +- kernel/compat.c | 8 +-- kernel/futex_compat.c | 2 +- kernel/sched/core.c | 4 +- kernel/signal.c | 2 +- kernel/time/hrtimer.c | 8 +-- kernel/time/posix-stubs.c | 18 ++--- kernel/time/posix-timers.c | 30 ++++----- kernel/time/time.c | 58 ++++++++-------- net/bluetooth/hci_sock.c | 2 +- net/compat.c | 22 +++--- sound/core/pcm_compat.c | 14 ++-- sound/core/rawmidi_compat.c | 2 +- sound/core/timer_compat.c | 2 +- 44 files changed, 252 insertions(+), 259 deletions(-) delete mode 100644 include/linux/compat_time.h
