x32 syscalls starting with number 512 are compat syscalls that operate
on compat types. Set COMPAT_SYSCALL_TYPES flag to these syscall entries
and make get_syscall_args truncate arguments of syscalls that have this
flag set, to avoid unpleasant alternative of adding multiple
widen_to_ulong invocations to individual syscall parsers.
preadv, pwritev, preadv2, and pwritev2 are exceptions: while these
syscalls operate on compat types, the offset argument has a regular
64-bit type, so the automatic argument truncation cannot be applied.
* defs.h (COMPAT_SYSCALL_TYPES): New macro.
* syscall.c (CST): New macro, defined to COMPAT_SYSCALL_TYPES.
* linux/ia64/syscallent.h: Do not include "../i386/syscallent.h"

* tests/nsyscalls.c (CST): Likewise.
Use an unsigned type for syscall numbers as they are not intended
for signed arithmetics. Introduce kernel_scno_t as a typedef
to unsigned long, that could be changed later to kernel_ulong_t.
* kernel_types.h (kernel_scno_t): New type, typedef to unsigned long.
* defs.h (struct tcb): Change type of scno field from long

(shuffle_scno): Change return type from long to kernel_scno_t.
(syscall_name): Change argument type from long to kernel_scno_t.
* linux/aarch64/set_scno.c: Note the kernel commit that introduced
NT_ARM_SYSTEM_CALL support.

PTRACE_SET_SYSCALL support.
* linux/sparc/set_scno.c: Note the kernel commit that introduced
reloading from the syscall number register.
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.
* exit.c: Remove.
* Makefile.am (strace_SOURCES): Remove exit.c.
* linux/dummy.h (sys_exit): Alias to printargs_d.
* strace.c (ptrace_setoptions): Add PTRACE_O_TRACEEXIT bit.
(print_event_exit): New function.
(trace): Use it in case of PTRACE_EVENT_EXIT.
* syscall.c (trace_syscall_entering): Remove special handling
of SEN_exit.
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.
* linux/crisv10/syscallent.h: New file.
* linux/crisv32/syscallent.h: Likewise.
* Makefile.am (EXTRA_DIST): Add them.
This change moves remaining arch specific getregs_old code into
appropriate arch subdirectories and removes unnecessary code
duplication.
* linux/getregs_old.h: New file.
* linux/powerpc/getregs_old.h: Likewise.
* linux/powerpc64/getregs_old.h: Likewise.
* linux/x86_64/getregs_old.h: Likewise.
* Makefile.am (EXTRA_DIST): Add them.
* syscall.c: Include "getregs_old.h".
[X86_64 || POWERPC]: Remove.
[ARCH_REGS_FOR_GETREGSET] (ptrace_getregset_or_getregs): Define
to ptrace_getregset.
[ARCH_REGS_FOR_GETREGS] (ptrace_getregset_or_getregs): Define
to ptrace_getregs.
(get_regs): Check for ptrace_getregset_or_getregs instead
of ARCH_REGS_FOR_GETREGSET and ARCH_REGS_FOR_GETREGS. Use
ptrace_getregset_or_getregs instead of ptrace_getregset and
ptrace_getregs. Check for HAVE_GETREGS_OLD instead of X86_64
and POWERPC. Use use_getregs_old instead of getregset_support
and old_kernel.
Why gcc didn't complain about it? It is definitely an index clash.
* linux/x32/syscallent.h: Change initializer indices for empty records from
[327 ... 511] to [329 ... 511].
Since create_module syscall is present only in kernels before Linux 2.6
and strace does not support those kernels, there is no use to keep this
parser any longer.
* bjm.c (SYS_FUNC(create_module)): Remove.
* linux/dummy.h (sys_create_module): Add stub alias.
fadvise_64_64 decoder used before this change prints different sign
of the "len" argument (loff_t vs size_t).
* linux/x32/syscallent.h (fadvise64): Replace SEN(fadvise64_64)
with SEN(fadvise64).
This change is no-op yet, but things will change when decoder
of fadvise64 syscall get fixed.
* linux/sh64/syscallent.h (fadvise64_64): Replace SEN(fadvise64)
with SEN(fadvise64_64).
* linux/sparc64/syscallent.h (fadvise64_64): Likewise.
* linux/64/ioctls_inc.h: Update from linux v4.8 using ioctls_gen.sh.
* linux/32/ioctls_inc_align32.h: Likewise.
* linux/32/ioctls_inc_align64.h: Likewise.
As io_setup syscall allocates some memory using do_mmap_pgoff, and
io_destroy deallocates this memory using vm_munmap, set TRACE_MEMORY
flag for all sysentries of io_setup and io_destroy using the following
oneliner:
sed -ri '/io_setup|io_destroy/ s/0,/TM,/' linux/*/syscallent*.h
* linux/*/syscallent*.h (io_setup, io_destroy): Change sys_flags to TM.
* file.c: Move redefinition of types that might be used
to define struct stat ...
* linux/asm_stat.h: ... here.
* tests/xstatx.c: Remove redefinition of stat types.
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.
* Makefile.am (strace_SOURCES): Add it.
* linux/x32/asm_stat.h: New file, include "x86_64/asm_stat.h".
* linux/sparc/arch_sigreturn.c (arch_sigreturn): Parametrize
member types of struct signal_frame.
* linux/sparc64/arch_sigreturn.c (sparc64_arch_sigreturn,
sparc32_arch_sigreturn): New functions.
(arch_sigreturn): Use them.
The structures defined in asm/termbits.h have the same size
on sparc and sparc64.
* linux/sparc64/ioctls_arch0.h (TCGETS, TCGETS2, TCSETS, TCSETS2,
TCSETSF, TCSETSF2, TCSETSW, TCSETSW2): Sync with
linux/sparc/ioctls_arch0.h
This fixes compilation warning that ARCH_PC_REG is redefined.
* linux/powerpc64/arch_regs.c (ARCH_PC_REG): Undefine before
the new definition.
* linux/sparc64/arch_regs.c (ARCH_PC_REG): Likewise.
* linux/s390x/arch_regs.c (ARCH_PC_REG): Remove, it is already defined
in just included linux/s390/arch_regs.c.
* linux/x32/arch_regs.c (ARCH_PC_REG): Remove, it is already defined
in just included linux/x86_64/arch_regs.c.
Fix inconsistency between syscall and ioctl entries on sparc64.
Make layout of personalities on sparc64 the same as on other
architectures that support two personalities.
* defs.h [SPARC64] (PERSONALITY0_WORDSIZE): Change to 8.
[SPARC64] (PERSONALITY1_WORDSIZE): Change to 4.
* linux/sparc64/get_scno.c (arch_get_scno): Swap personality numbers.
* linux/sparc64/ioctls_arch1.h: Rename to ioctls_arch0.h.
* linux/sparc64/ioctls_arch0.h: Rename to ioctls_arch1.h.
* linux/sparc64/ioctls_inc0.h: Rename to ioctls_inc1.h.
* linux/sparc64/ioctls_inc1.h: Rename to ioctls_inc0.h.
