ed37c8d64b Remove UNDEFINED_SCNO
Since UNDEFINED_SCNO is set if and only if !SCNO_IS_VALID
and since tcp->s_ent can only be set to &sysent[tcp->scno]
(or to &unknown, but only when !SCNO_IS_VALID), there is no need
to check for UNDEFINED_SCNO before calling syscall_name(tcp->scno).

a8fce09e34 mpers: add support of conditionally compiled printers
We used to declare and define all printers marked with
MPERS_PRINTER_DECL, including ifdef'ed ones.  That approach left us
no way to conditionally compile mpersified printers, which was not
a problem until btrfs ioctls appeared on the horizon.

With this change, those mpersified printers that are not going
to be compiled are also won't be declared and won't be added to
struct_printers.

This is implemented by filtering all source files containing
MPERS_PRINTER_DECL markers through CPP.  As a nice side effect, this
also lifts an ugly requirement of writing all MPERS_PRINTER_DECL
declarations in a single line.

* README-mpers: Update description of MPERS_PRINTER_DECL syntax.
* defs.h [IN_MPERS_BOOTSTRAP] (MPERS_PRINTER_DECL): Turn into
a recursive variadic macro.
[!IN_MPERS_BOOTSTRAP] (MPERS_PRINTER_DECL): Turn into a variadic macro.

(CLEANFILES): Add $(mpers_preproc_files).
(%.c.mpers.i): New rule.
(printers.h, %_printer_decls.h, %_printer_defs.h): Use
mpers_preproc_files instead of srcdir_mpers_source_files,
use mpers_printer_decl_pattern.
* .gitignore: Add /*.mpers.i.

3c17d1b5e1 Implement caching of print_sockaddr_by_inode
As -yy parser, compared to -y, needs to do at least 5 extra syscalls
(getxattr, socket, sendmsg, recvmsg, close) to print socket details,

The caching is safe since sockets do not change their addresses after

34683e3926 Fix SYS_FUNC and SEN macros for musl
The syscall_name argument was subject to macro expansion because
it was passed down to other macros before it was prefixed.

musl libc defines lfs64 names as macros (e.g. fstat64 as fstat)
so SYS_FUNC(fstat64) was expanded to sys_fstat.

This change adds the prefix before the name is passed to other macros,
i.e. the argument of SYS_FUNC_NAME is already prefixed with sys_.

* defs.h (SYS_FUNC): Add sys_ prefix to SYS_FUNC_NAME's argument.
(SYS_FUNC_NAME): Do not add sys_ prefix to MPERS_FUNC_NAME's argument.
* linux/ia64/syscallent.h (SYS_FUNC_NAME): Do not add sys_ prefix
to MPERS_FUNC_NAME's argument.
* syscall.c (SEN_NAME): Remove.
(SEN): Replace SEN_NAME call with its definition.  Add sys_ prefix
to SYS_FUNC_NAME's argument.

da126fbd77 Replace HAVE_LITTLE_ENDIAN_LONG_LONG with WORDS_BIGENDIAN
* defs.h: Use WORDS_BIGENDIAN instead of HAVE_LITTLE_ENDIAN_LONG_LONG.
* configure.ac (AC_LITTLE_ENDIAN_LONG_LONG): Remove.
* m4/long_long.m4: Remove.

c37173f76d aarch64: swap 64-bit and 32-bit personalities
Let native 64-bit personality be personality 0, and 32-bit personality
be personality 1, to follow the traditional layout used for other
architectures.

* defs.h [AARCH64]: Swap PERSONALITY0_WORDSIZE and
PERSONALITY1_WORDSIZE, remove DEFAULT_PERSONALITY.
[AARCH64 && HAVE_M32_MPERS]: Rename PERSONALITY1_* to PERSONALITY0_*.
* file.c [AARCH64 || defined X86_64 || defined X32]: Define
STAT32_PERSONALITY for AARCH64 as well.
* syscall.c (update_personality) [AARCH64]: Adjust PERSONALITY_NAMES.
* linux/aarch64/errnoent1.h: Adjust comment.
* linux/aarch64/get_error.c (get_error): Adjust tcp->currpers check.
* linux/aarch64/get_syscall_args.c (get_syscall_args): Likewise.
* linux/arm/arch_sigreturn.c (arch_sigreturn) [AARCH64]: Likewise.
* linux/aarch64/get_scno.c (arch_get_scno): Adjust update_personality
invocations.
* linux/aarch64/ioctls_arch0.h: Swap with ...
* linux/aarch64/ioctls_arch1.h: ... this file.
* linux/aarch64/ioctls_inc0.h: Swap with ...
* linux/aarch64/ioctls_inc1.h: ... this file.
* linux/aarch64/syscallent.h: Swap with ...
* linux/aarch64/syscallent1.h: ... this file.

8b6046a052 ioctl: allow to stop decoding number
For some ioctls, like from drm, the identification of the correct ioctl
is done by custom code.  Specifying IOCTL_NUMBER_STOP_LOOKUP on
return of ioctl_decode_command_number() disables further calls to
ioctl_lookup().

* defs.h (IOCTL_NUMBER_UNKNOWN, IOCTL_NUMBER_HANDLED,
IOCTL_NUMBER_STOP_LOOKUP): Add macros representing ioctl number state
decoding.
* ioctl.c (SYS_FUNC(ioctl)): Skip ioctl_lookup() when
ioctl_decode_command_number() returns a value with
IOCTL_NUMBER_STOP_LOOKUP flag is set.

* defs.h (error_msg_and_help): New prototype.
* strace.c (error_msg_and_help): New function.
(error_opt_arg, init): Use it.
(usage): Remove unnecessary arguments.
* count.c: Use the new function.

5cb45b25a3 mpers: skip xlat struct definitions in mpers mode
Avoid duplicate definitions of xlat structures in files
compiled in mpers mode.

Each xlat file defines the corresponding xlat struct with
either global or local visibility using the following rules:

- if xlat struct declaration is available in defs.h,
  a global definition is provided in regular mode,
  and nothing is provided in mpers mode;
- otherwise, if xlat file is included by a mpers source file,
  a global definition is provided in regular mode
  (unless no mpers mode is supported on this architecture,
  in that case, a local definition is provided instead),
  and a declaration is provided in mpers mode;
- otherwise, a local definition is provided in regular mode,
  and an error message is printed in mpers mode.

Fallback definitions of constants provided by xlat files
remain available in all modes.

* bootstrap: Invoke generate_mpers_am.sh before xlat/gen.sh.
* defs.h (adjtimex_modes, adjtimex_status, sigev_value): Remove.
* generate_mpers_am.sh: Generate mpers_xlat.h.
* Makefile.am (EXTRA_DIST): Add mpers_xlat.h.
* print_sigevent.c: Include "xlat/sigev_value.h" unconditionally.
* print_timex.c: Include "xlat/adjtimex_modes.h" and
"xlat/adjtimex_status.h" unconditionally.
* xlat/gen.sh (cond_xlat): Move printing of fallback definitions ...
(cond_def): ... here.
(gen_header): Check also mpers_xlat.h for global declarations
of xlat structures.
Process input file twice, first time print directives
only, second time print everything.
Wrap struct xlat into #ifdef IN_MPERS ... #else ... #endif.
* xlat/getrandom_flags.in: Cleanup.
