ioctl: take all 32 bits of ioctl commands into account Historically, only 16 bits (8-bit number and 8-bit type) of 32-bit ioctl commands were used for decoding, which was the source for numerous annoying collisions like this: ioctl(0, SNDCTL_TMR_TIMEBASE or SNDRV_TIMER_IOCTL_NEXT_DEVICE or TCGETS, {B38400 opost isig icanon echo ...}) = 0 ioctl(0, MGSL_IOCGPARAMS or MMTIMER_GETRES or MTIOCTOP or SNDCTL_MIDI_MPUMODE, 0x7fffd47f7338) = -1 ENOTTY (Inappropriate ioctl for device) The solution is to use all 32 bits for decoding, not just "number" and "type", but also "size" and "direction". As some architectures override defaults that come from asm-generic/ and provide alternative definitions for some ioctl commands, we support per-architecture ioctl definitions and merge them with common definitions at build time. During the merge, we used to keep both generic and architecture-specific definitions, now architecture-specific definitions have precedence over generic ones -- ioctlsort omits definitions from asm-generic/ for those ioctl names that have different definitions in asm/. Additional bits of "direction" are architecture specific -- the number of bits and their values differ between architectures. To reduce architecture differences in the source code, we keep "direction" in symbolic form and compile it in ioctlsort. Additional bits of "size" are also architecture specific -- not only the number of bits differ between architectures, but sizes of many types depend on sizeof(long). To reduce architecture differences in the source code, we keep 32-bit and 64-bit versions of common ioctl definitions, and use the appropriate version for each architecture and personality. To implement this, the tools for generating ioctl definitions from kernel headers have been rewritten, and the source format of ioctl definitions has been extended. The final ioctlent*.h files that are included by syscall.c are now generated from source ioctls_inc*.h and ioctls_arch*.h files at build time with ioctlsort. * ioctl.c (ioctl_lookup): Use all 32 bits of ioctl command code. * ioctlsort.c: Rewritten. * linux/32/ioctls_inc.h: New file. * linux/64/ioctls_inc.h: New file. * linux/aarch64/ioctls_arch0.h: New file. * linux/aarch64/ioctls_arch1.h: New file. * linux/aarch64/ioctls_inc0.h: New file. * linux/aarch64/ioctls_inc1.h: New file. * linux/alpha/ioctls_arch0.h: New file. * linux/alpha/ioctls_inc0.h: New file. * linux/arc/ioctls_arch0.h: New file. * linux/arc/ioctls_inc0.h: New file. * linux/arm/ioctls_arch0.h: New file. * linux/arm/ioctls_inc0.h: New file. * linux/avr32/ioctls_arch0.h: New file. * linux/avr32/ioctls_inc0.h: New file. * linux/bfin/ioctls_arch0.h: New file. * linux/bfin/ioctls_inc0.h: New file. * linux/hppa/ioctls_arch0.h: New file. * linux/hppa/ioctls_inc0.h: New file. * linux/i386/ioctls_arch0.h: New file. * linux/i386/ioctls_inc0.h: New file. * linux/ia64/ioctls_arch0.h: New file. * linux/ia64/ioctls_inc0.h: New file. * linux/m68k/ioctls_arch0.h: New file. * linux/m68k/ioctls_inc0.h: New file. * linux/metag/ioctls_arch0.h: New file. * linux/metag/ioctls_inc0.h: New file. * linux/microblaze/ioctls_arch0.h: New file. * linux/microblaze/ioctls_inc0.h: New file. * linux/mips/ioctls_arch0.h: New file. * linux/mips/ioctls_inc0.h: New file. * linux/or1k/ioctls_arch0.h: New file. * linux/or1k/ioctls_inc0.h: New file. * linux/powerpc/ioctls_arch0.h: New file. * linux/powerpc/ioctls_inc0.h: New file. * linux/powerpc64/ioctls_arch0.h: New file. * linux/powerpc64/ioctls_arch1.h: New file. * linux/powerpc64/ioctls_inc0.h: New file. * linux/powerpc64/ioctls_inc1.h: New file. * linux/s390/ioctls_arch0.h: New file. * linux/s390/ioctls_inc0.h: New file. * linux/s390x/ioctls_arch0.h: New file. * linux/s390x/ioctls_inc0.h: New file. * linux/sh/ioctls_arch0.h: New file. * linux/sh/ioctls_inc0.h: New file. * linux/sh64/ioctls_arch0.h: New file. * linux/sh64/ioctls_inc0.h: New file. * linux/sparc/ioctls_arch0.h: New file. * linux/sparc/ioctls_inc0.h: New file. * linux/sparc64/ioctls_arch0.h: New file. * linux/sparc64/ioctls_arch2.h: New file. * linux/sparc64/ioctls_inc0.h: New file. * linux/sparc64/ioctls_inc2.h: New file. * linux/tile/ioctls_arch0.h: New file. * linux/tile/ioctls_arch1.h: New file. * linux/tile/ioctls_inc0.h: New file. * linux/tile/ioctls_inc1.h: New file. * linux/x32/ioctls_arch0.h: New file. * linux/x32/ioctls_arch1.h: New file. * linux/x32/ioctls_inc0.h: New file. * linux/x32/ioctls_inc1.h: New file. * linux/x86_64/ioctls_arch0.h: New file. * linux/x86_64/ioctls_arch1.h: New file. * linux/x86_64/ioctls_inc0.h: New file. * linux/x86_64/ioctls_inc1.h: New file. * linux/xtensa/ioctls_arch0.h: New file. * linux/xtensa/ioctls_inc0.h: New file. * linux/aarch64/ioctlent.h.in: Remove. * linux/aarch64/ioctlent1.h: Remove. * linux/alpha/ioctlent.h.in: Remove. * linux/arc/ioctlent.h.in: Remove. * linux/arm/ioctlent.h.in: Remove. * linux/avr32/ioctlent.h.in: Remove. * linux/bfin/ioctlent.h.in: Remove. * linux/hppa/ioctlent.h.in: Remove. * linux/i386/ioctlent.h.in: Remove. * linux/ia64/ioctlent.h.in: Remove. * linux/ioctlent.h.in: Remove. * linux/ioctlent.sh: Remove. * linux/m68k/ioctlent.h.in: Remove. * linux/metag/ioctlent.h.in: Remove. * linux/microblaze/ioctlent.h.in: Remove. * linux/mips/ioctlent.h.in: Remove. * linux/mips/ioctlent.sh: Remove. * linux/or1k/ioctlent.h.in: Remove. * linux/powerpc/ioctlent.h.in: Remove. * linux/powerpc64/ioctlent.h: Remove. * linux/powerpc64/ioctlent1.h: Remove. * linux/s390/ioctlent.h.in: Remove. * linux/s390x/ioctlent.h.in: Remove. * linux/sh/ioctlent.h.in: Remove. * linux/sh64/ioctlent.h.in: Remove. * linux/sparc/ioctlent.h.in: Remove. * linux/sparc64/ioctlent.h.in: Remove. * linux/sparc64/ioctlent2.h: Remove. * linux/tile/ioctlent.h.in: Remove. * linux/tile/ioctlent1.h: Remove. * linux/x32/ioctlent.h.in: Remove. * linux/x32/ioctlent1.h: Remove. * linux/x86_64/ioctlent.h.in: Remove. * linux/x86_64/ioctlent1.h: Remove. * linux/xtensa/ioctlent.h.in: Remove. * linux/x86_64/ioctlent2.h: Include ioctlent0.h instead of ioctlent.h. * syscall.c (struct_ioctlent ioctlent0): Likewise. * Makefile.am: Remove all ioctlent-related definitions.
