For the reason described in commit v4.10-517-gcfde1e3, a correct
definition of struct stat for x32 personality is necessary to enable
"asm_stat.h" with -mx32 on x86_64.
* linux/x32/asm_stat.h: Rename to ...
* linux/x86_64/asm_stat.h: ... new file.

as "unsigned int".
[S390 || S390X]: Skip ipc cubcalls that have non-zero version.
[SPARC64]: Likewise, for the native personality.
Save ipc cubcall version for later use by specific ipc parsers.
* ipc_msg.c (SYS_FUNC(msgrcv)): Handle non-zero ipc subcall version.
[SPARC64]: Handle non-ipc_kludge case for the native personality.

Introduce a general socket netlink parser which prints the header and
a string for the remaining part of the buffer. It doesn't handle all
the netlink flags and types yet because the parser needs more
information, this will be implemented later.
* net.c (decode_sockbuf): New function.
(SYS_FUNC(send), SYS_FUNC(sendto), SYS_FUNC(recv), SYS_FUNC(recvfrom)):
Use it instead of printstr.

(block_ioctl): Move parser of HDIO_GETGEO to hdio.c.
* defs.h (hdio_ioctl): New prototype.
* ioctl.c (ioctl_decode): Call hdio_ioctl for ioctl type 0x03.
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.
All callers changed.

(%.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".
(netlink_send_query, netlink_parse_response, netlink_print): New
functions.
(print_sockaddr_by_inode): Hook up netlink_print.
* m4/ax_code_coverage.m4: Update to serial 16.
* 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.

tests without inclusion of defs.h header file.
* defs.h (struct xlat, XLAT, XLAT_END): Move ...
* xlat.h: ... here.
* Makefile.am (strace_SOURCES): Add xlat.h.
For each given architecture only one of these two syscalls has a
syscallent entry. When each parser is placed into a separate file,
moving to libstrace ensures that only one of them that is need
is linked into strace executable.
* sync_file_range.c (SYS_FUNC(sync_file_range2)): Move ...
* sync_file_range2.c: ... here.
* Makefile.am (strace_SOURCES): Move sync_file_range.c ...
(libstrace_a_SOURCES): ... here. Add sync_file_range2.c.
(strace_SOURCES_c): Add filtered libstrace_a_SOURCES.

configuration. Create a library for the purpose of keeping such
compilation units.

set to $(libmpers_CFLAGS).
Do not rely on "struct sigevent.__pad" being located at the same address
as "struct sigevent.sigev_notify_thread_id", it's not the case with musl
libc. Do not rely on struct sigevent definition at all to access
sigev_notify_thread_id.
* configure.ac (AC_CHECK_MEMBERS): Remove struct sigevent._sigev_un._pad
and struct sigevent.__pad.
* sigevent.h: New file.

that return a pair of values using the same mechanism as pipe syscall.
* alpha.c: New file.
* Makefile.am (strace_SOURCES): Add it.
* linux/alpha/syscallent.h [20]: Change SEN(getpid) to SEN(getxpid).

Before this change, all files that exist since 20th century had
copyright headers, while most files that appeared later didn't. This
change fixes the inconsistency by adding missing copyright headers.
It doesn't mean that copyright headers became maintained. In my view,
git history provides much better information on this subject and is much
more accurate than copyright headers.
As tests-m*32/Makefile.am files now refer to proper arch specific
directories, it's possible to relocate x32 <asm/stat.h> replacement
to its arch specific directory.
* linux/x86_64/asm_stat.h: Move ...
* linux/x32/asm_stat.h: ... here, remove x32 guard.
* Makefile.am (strace_SOURCES): Remove linux/x86_64/asm_stat.h.
Some old kernel headers, Ubuntu 14.04 in particular, provide
<asm/stat.h> editions that are completely wrong for x32.
Workaround this issue by providing a replacement.
* linux/x86_64/asm_stat.h: New file.
* linux/x32/asm_stat.h: Likewise.
* Makefile.am (strace_SOURCES): Add them.
Apparently, there are only two types of instruction pointer printers
depending on the architecture: those that print a register that was
fetched earlier, and those that fetch a register themselves using upeek.
With this change, architectures of the first type have ARCH_PC_REG
defined in their arch_regs.c file, architectures of the first type
have ARCH_PC_PEEK_ADDR defined there, and the common code in syscall.c
uses these macros to print the instruction pointer.

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.

options to mpers.sh's CPPFLAGS.

While it appears to work with GNU make, it has to be fixed nevertheless.

In files generated by mpers scripts, includes directives are taken from
original files where the type definition was done. This causes to
include defs.h in multiple files. defs.h includes printers.h header,
which is a generated header.
This patch add an explicit dependency to printers.h for the mpers
scripts.
* Makefile.am (mpers-m%.stamp): Add printers.h to order-only
prerequisites.

On some systems missing gnu/stubs-*.h files make -m32/-mx32 compilation
checks fail. As we want to support multiple personalities despite of
this limitation, workaround the check by creating empty gnu stub files
if necessary.
* m4/mpers.m4 (st_MPERS): Check for the gnu stub file. Create an empty
gnu stub file if the system one is missing.
* Makefile.am (DISTCLEANFILES): Add gnu/stubs-32.h and gnu/stubs-x32.h.
Fix multiple personalities support in parsers of utimes, futimesat,
and utimensat syscalls by introducing two mpersified printers:
print_timeval_pair and print_timespec_utime_pair.
* print_time.c: New file.
* Makefile.am (strace_SOURCES): Add it.
* utimes.c (decode_utimes): Remove.
(sys_utimes, sys_futimesat): Use print_timeval_pair instead
of decode_utimes.
(sys_utimensat): Use print_timespec_utime_pair instead of decode_utimes.
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.

Personality 1 for sparc and sparc64 appears to be an old attempt
to support stracing Solaris binaries.
It stalled after the only syscall, solaris_open, was covered:
all other solaris_foo's are printargs.
This change deletes personality 1. Now sparc is an one-personality
arch, and sparc64 is a two-personality one.
For clarity, pure renaming of personality 2 files to personality 1 for sparc64
is performed in the next commit - this prevents a state where syscallent1.h
seems to indergo a lot of changes, where in fact in is deleted, and then
replaced by syscallent2.h
Therefore, tree at this commit will not build.

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.

* tests/uid.test: Trace getgroups/getgroups32 syscalls.
Define two sets of parsers on architectures that support (either
directly or via multiarch) 16-bit and 32-bit uid/gid syscalls
simultaneously. Since the code in these two sets is essentially
the same and the key difference between them is the size of uid_t,
implement it by parametrizing uid_t and names of parser functions.
* defs.h (NEED_UID16_PARSERS): New macro.
* linux/syscall.h [NEED_UID16_PARSERS] (sys_chown16, sys_fchown16,
sys_getresuid16, sys_getuid16, sys_setfsuid16, sys_setresuid16,
sys_setreuid16, sys_setuid16): New prototypes.
* linux/dummy.h (sys_geteuid16): Alias to sys_getuid16.
(sys_getegid16, sys_getgid16, sys_getresgid16, sys_setfsgid16,
sys_setgid16, sys_setregid16, sys_setresgid16): Alias to corresponding
sys_*uid16 functions.
* uid.c: Stop including <asm/posix_types.h>.
Parametrize uid_t and names of all exported functions.
(get_print_uid): New function.
(sys_getresuid): Use it.
(printuid): Check for (uid_t) -1.
* uid16.c: New file.
* Makefile.am (strace_SOURCES): Add it.
* linux/arm/syscallent.h: Use sys_chown16, sys_fchown16, sys_getegid16,
sys_geteuid16, sys_getgid16, sys_getresgid16, sys_getresuid16,
sys_getuid16, sys_setfsgid16, sys_setfsuid16, sys_setgid16,
sys_setregid16, sys_setresgid16, sys_setresuid16, sys_setreuid16,
and sys_setuid16 parsers for *chown and [gs]et*[gu]id syscall entries.
