When cross-compiling, ioctlsort must obtain _IOC_* values from the
host, build's values may be incompatible.
* ioctl_iocdef.c: New file.
* Makefile.am (EXTRA_DIST): Add it.
(ioctl_iocdef.i, ioctl_iocdef.h): New rules.
(ioctlsort%.o): Depend on ioctl_iocdef.h.
(CLEANFILES): Add ioctl_iocdef.h and ioctl_iocdef.i.
* ioctlsort.c: Include "ioctl_iocdef.h" instead of <linux/ioctl.h>.

* print_sg_req_info.c: New file.
* Makefile.am (strace_SOURCES): Add it.
* xlat/sg_scsi_reset.in: New file.
* scsi.c: Include "xlat/sg_scsi_reset.h".
(scsi_ioctl): Implement decoding of all SG_* ioctl commands.
Drop custom vfprintf implementation that was disabled by default.
Apparently nobody tests strace with this vfprintf enabled, otherwise
multiple uses of format specifiers not supported by this custom vfprintf
would not left unnoticed.
The GNU C library is not the only libc available, so those who want
faster implementations of libc functions are encouraged to try building
strace with other libc implementations.
* vsprintf.c: Remove.
* Makefile.am (strace_SOURCES): Remove vsprintf.c.
* defs.h (USE_CUSTOM_PRINTF, strace_vfprintf): Remove.
* strace.c (tprintf): Replace strace_vfprintf with vfprintf.
Generate scno.h using only those tools that are available for cross
build. This allows to use scno.h during the build of strace itself.
* scno.am: New file.
* scno.head: New file.
* Makefile.am (EXTRA_DIST): Add it.
* tests/generate_scno.c: Remove.
* tests/.gitignore: Remove generate_scno.

(CLEANFILES): Remove scno.h.
(scno.h, $(scno_dependants)): Remove rules.

print_dev_t function for printing device numbers.

(decode_mknod): Use print_dev_t function for printing device number.
* print_struct_stat.c: Do not include <sys/sysmacros.h>.
(print_struct_stat): Use print_dev_t function for printing device
numbers.

Commit dc427d50d9 enabled a number of extra
warning flags through configure.ac. The configure script will determine
dynamically if CC supports these flags before adding them to WARN_CFLAGS.
ioctlsort is compiled with CC_FOR_BUILD, rather than CC. Nevertheless,
the flags passed to this compilation also include WARN_CFLAGS (through
AM_CFLAGS). This is incorrect: in a cross-compilation use case, CC
and CC_FOR_BUILD are not the same. The former is the cross-compiler,
the latter is the host compiler. Both may be of different versions
and support different warning flags.
In particular, this posed a problem when cross-compiling with a host
compiler gcc 4.1, which does not support all the new flags:
/usr/bin/gcc -DHAVE_CONFIG_H -I./linux/arm -I./linux/arm -I./linux
-I./linux -I. -I. -I/host-sysroot/usr/include -Wall -Wempty-body
-Wformat-security -Wignored-qualifiers -Winit-self -Wlogical-op
-Wmissing-parameter-type -Wnested-externs -Wold-style-declaration

* valgrind.supp: New file.
* Makefile.am (EXTRA_DIST): Add it.

Do not assume that some syscalls do not generate syscall-exit-stops.
When syscalls fail for any reason they may generate syscall-exit-stops.
The solution is to wait for an actual exit reported by PTRACE_EVENT_EXIT
and print the end of unfinished exiting syscall properly.

The incomplete CRIS support introduced by commit v4.5.18-77-gea0e6e8
should not have been merged because it lacks essential parts, e.g.
syscall tables.
This change adds missing syscall tables for crisv10 and crisv32.

ptrace_getregs. Check for HAVE_GETREGS_OLD instead of X86_64
and POWERPC. Use use_getregs_old instead of getregset_support

This will be needed to implement fault injection on those architectures
that lack PTRACE_SETREGSET/PTRACE_SETREGS support.

This allows testing of MPERS_IS_* macros in pre-MPERS_DEFS parts
of source code.

passed to mpers.sh.

For the reason described in commit v4.10-517-gcfde1e3, a correct

the netlink flags and types yet because the parser needs more
information, this will be implemented later.

(SYS_FUNC(send), SYS_FUNC(sendto), SYS_FUNC(recv), SYS_FUNC(recvfrom)):
Use it instead of printstr.

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.
* linux/netlink_diag.h: New file.
* Makefile.am (EXTRA_DIST): Add it.
* socketutils.c: Include it and "xlat/netlink_protocols.h".

functions.
(print_sockaddr_by_inode): Hook up netlink_print.

* Makefile.am (CODE_COVERAGE_LCOV_OPTIONS): Remove.
(CODE_COVERAGE_GENHTML_OPTIONS): Update, add prefix.
(CODE_COVERAGE_BRANCH_COVERAGE): Set to 1.
As values of some ioctl macros differ between personalities, these
personality specific ioctl macros should be properly defined for
mpersified code. Implement this by redefining personality specific
ioctl macros from ioctlent*.h for each file that includes MPERS_DEFS.
* Makefile.am (ioctl_macros_h): New variable.
(ioctl_macros%.h): New rule.
(BUILT_SOURCES, CLEANFILES): Add $(ioctl_macros_h).
(m%_type_defs.h): #include MPERS_$(mpers_PREFIX)IOCTL_MACROS.
* defs.h [HAVE_M32_MPERS] (MPERS_m32_IOCTL_MACROS): New macro.
[HAVE_MX32_MPERS] (MPERS_mx32_IOCTL_MACROS): Likewise.
