Introduce SYS_FUNC macro to declare and define all syscall parsers.
* Makefile.am (BUILT_SOURCES, CLEANFILES): Add sys_func.h.
(sys_func.h): New rule.
* defs.h (SYS_FUNC_NAME, SYS_FUNC): New macros.
* linux/syscall.h: Include "sys_func.h".
[NEED_UID16_PARSERS]: Use SYS_FUNC to declare uid16 syscall parsers.
Remove other declarations.
* linux/alpha/syscallent.h (160, 161): Add sys_ prefix to osf_statfs
and osf_fstatfs syscall parsers.
* *.c: Use SYS_FUNC to define syscall parsers.
* file.c (sys_stat, sys_fstat): Collect in one place right before
the definition of printstat64.
(sys_stat64, sys_fstat64): Collect in one place right after the
definition of printstat64.
* file.c (printstat) [X32]: Define.
(printstat64) [X32]: Use "struct stat64" instead of "struct stat".
Use printstat for x32 personality processes.
(printstat64_x32): Remove.
(sys_stat64, sys_fstat64) [X32]: Use printstat64 instead of
printstat64_x32.
* file.c [X32]: Do not define "struct stat" and "struct
__old_kernel_stat" locally, use definitions provided by <asm/stat.h>.
Do not define "struct stat64" exclusively, reuse another definition
added earlier for X86_64.
* printstat.h: New file.
* Makefile.am (strace_SOURCES): Add it.
* file.c: Include "printstat.h".
(do_printstat): Move to printstat.h, parametrize its name
and struct stat.
* file.c (realprintstat): Adjust format strings so that all 64-bit
integer fields are printed with %llu format, and %u format is used for
all the rest. Rename to do_printstat.
(printstat, printoldstat): Update callers.
There are no symbolic constants defined for struct stat.st_flags,
so decode this rare field as unsigned int.
* xlat/fileflags.in: Remove.
* file.c (realprintstat, printstat64) [HAVE_STRUCT_STAT_ST_FLAGS]:
Decode struct stat.st_flags as unsigned int.
Remove the code that supports struct stat.st_aclcnt and stat.st_level
decoding -- these fields are not defined in system headers.
* configure.ac (AC_CHECK_MEMBERS): Remove struct stat.st_aclcnt and
struct stat.st_level.
* file.c (realprintstat, printstat64)
[HAVE_STRUCT_STAT_ST_ACLCNT || HAVE_STRUCT_STAT_ST_LEVEL]: Remove.
* link.c: New file.
* Makefile.am (strace_SOURCES): Add it.
* file.c: Move sys_link, sys_linkat, sys_unlinkat, sys_symlinkat, and
related code to link.c.
* printmode.c: New file.
* Makefile.am (strace_SOURCES): Add it.
* defs.h (sprintmode): New prototype.
* file.c (sprintmode): Make global and move to printmode.c.
* xattr.c: New file.
* Makefile.am (strace_SOURCES): Add it.
* file.c: Move sys_setxattr, sys_fsetxattr, sys_getxattr, sys_fgetxattr,
sys_listxattr, sys_flistxattr, sys_removexattr, sys_fremovexattr,
and related code to xattr.c.
* sync_file_range.c: New file.
* Makefile.am (strace_SOURCES): Add it.
* file.c: Move sys_sync_file_range, sys_sync_file_range2, and related
code to sync_file_range.c.
Special parsers for mkdir and mkdirat are redundant because
sys_chmod and sys_fchmodat implement the same decoding.
* file.c (decode_mkdir, sys_mkdir, sys_mkdirat): Remove.
* linux/dummy.h (sys_mkdir): Alias to sys_chmod.
(sys_mkdirat): Alias to sys_fchmodat.
* linux/syscall.h (sys_mkdir, sys_mkdirat): Remove.
* pathtrace.c (pathtrace_match): Do not check for sys_mkdirat.
On Android, 32-bit arm and x86 use __kernel_mode_t (an unsigned short)
as their mode_t. The open(2) flags are actually an int, so high ones
like O_CLOEXEC get truncated if you coerce them to mode_t.
* defs.h (tprint_open_modes, sprint_open_modes): Change argument type
from mode_t to int.
* file.c (tprint_open_modes, sprint_open_modes): Likewise.
