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.

Add mpers support Add a subsystem for semi-automatical definition of how parsers should work with personality-dependent (mpers) types of tracee's data. Create auxiliary libraries containing mpers syscall parsers and printer functions, one library for each possible nonnative target personality. Currently some parsers do not handle differences in definitions of data types between personalities, namely LP64 and ILP32. When this is the case, long integers, pointers, and all compound types containing long and pointer members may be printed incorrectly, because of differences in sizes, offsets and alignments. Since in most cases these are the only differences in desired behaviour of parsers and printers for different personalities, a correct way would be to compile one source code into multiple parsers, differing only in definitions of mpers types. To get a definition of a given type for nonnative personality a very basic .c file containing a declaration of a variable of this type is being compiled for this personality (using -m32 or -mx32 compiler flag). Information about the type is then being extracted from this binary's DWARF debug info with an awk script and put into a corresponding header file. Resulting headers are being used to compile mpers variations of syscall parsers and printer functions. In addition to syscall parsers, there can occur a need to create mpers printing functions, which then can be called from many places in the code (for example, printsiginfo_at). Such functions (printers) are marked in a special manner. For each possible nonnative target personality a library is being created, containing mpers variations of syscall parsers and printers. Only syscall parsers from files marked in a special manner and specially marked functions from such files are being recompiled and included in these libraries. generate_mpers_am.sh is called by bootstrap to find the files from strace_SOURCES which include MPERS_DEFS. During compilation, these files are being inspected for inclusions of DEF_MPERS_TYPE, and nonnative variations of each included type are being generated by an awk script. Mpers parser names are being modified during inclusions of syscallent headers for nonnative personalities. Pointers to printers are being stored in structs struct_printers, and a master pointer printers is being updated on every set_personality. * README-mpers: New README explaining how to use mpers support. * empty.h: New empty file. * generate_mpers_am.sh: New file. * mpers.awk: Likewise. * mpers.sh: Likewise. * mpers_test.sh: Likewise. * mpers_type.h: Likewise. * Makefile.am (strace_SOURCES): Add empty.h and mpers_type.h.

Add mpers support Add a subsystem for semi-automatical definition of how parsers should work with personality-dependent (mpers) types of tracee's data. Create auxiliary libraries containing mpers syscall parsers and printer functions, one library for each possible nonnative target personality. Currently some parsers do not handle differences in definitions of data types between personalities, namely LP64 and ILP32. When this is the case, long integers, pointers, and all compound types containing long and pointer members may be printed incorrectly, because of differences in sizes, offsets and alignments. Since in most cases these are the only differences in desired behaviour of parsers and printers for different personalities, a correct way would be to compile one source code into multiple parsers, differing only in definitions of mpers types. To get a definition of a given type for nonnative personality a very basic .c file containing a declaration of a variable of this type is being compiled for this personality (using -m32 or -mx32 compiler flag). Information about the type is then being extracted from this binary's DWARF debug info with an awk script and put into a corresponding header file. Resulting headers are being used to compile mpers variations of syscall parsers and printer functions. In addition to syscall parsers, there can occur a need to create mpers printing functions, which then can be called from many places in the code (for example, printsiginfo_at). Such functions (printers) are marked in a special manner. For each possible nonnative target personality a library is being created, containing mpers variations of syscall parsers and printers. Only syscall parsers from files marked in a special manner and specially marked functions from such files are being recompiled and included in these libraries. generate_mpers_am.sh is called by bootstrap to find the files from strace_SOURCES which include MPERS_DEFS. During compilation, these files are being inspected for inclusions of DEF_MPERS_TYPE, and nonnative variations of each included type are being generated by an awk script. Mpers parser names are being modified during inclusions of syscallent headers for nonnative personalities. Pointers to printers are being stored in structs struct_printers, and a master pointer printers is being updated on every set_personality. * README-mpers: New README explaining how to use mpers support. * empty.h: New empty file. * generate_mpers_am.sh: New file. * mpers.awk: Likewise. * mpers.sh: Likewise. * mpers_test.sh: Likewise. * mpers_type.h: Likewise. * Makefile.am (strace_SOURCES): Add empty.h and mpers_type.h.
