	linux/ioctlent: unify them all
	This unifies all the ioctlent.h's in the linux subdir while still
	allowing each arch to maintain its own minor list.

	The basic method is:
	- each arch has linux/<arch>/ioctlent.h.in which defines only the
	arch-specific ioctls;
	- linux/ioctlent.h.in which defines only the common ioctls;
	- at build time, these two headers are combined and sorted to produce
	the linux/ioctlent.h file.

	This also requires a little tweaking of the include files since the
	common ioctlent.h is a built file.

	* linux/ioctlent.h: Split into linux/ioctlent.h.in and
	linux/i386/ioctlent.h.in, remove asm entries from the former, remove
	non-asm entries from the latter.
	* linux/alpha/ioctlent.h: Rename to linux/alpha/ioctlent.h.in, remove
	non-asm entries.
	* linux/bfin/ioctlent.h: Rename to linux/bfin/ioctlent.h.in, remove
	non-asm entries.

	non-asm entries.
	* linux/ia64/ioctlent.h: Rename to linux/ia64/ioctlent.h.in, remove
	non-asm entries.
	* linux/mips/ioctlent.h: Rename to linux/mips/ioctlent.h.in, remove
	non-asm entries.
	* linux/powerpc/ioctlent.h: Rename to linux/powerpc/ioctlent.h.in,
	remove non-asm entries.
	* linux/s390/ioctlent.h: Rename to linux/s390/ioctlent.h.in, remove
	non-asm entries.
	* linux/sh/ioctlent.h: Rename to linux/sh/ioctlent.h.in, remove
	non-asm entries.
	* linux/sparc/ioctlent.h: Rename to linux/sparc/ioctlent.h.in, remove
	non-asm entries.

	Show more details about signals received by traced processess
	* strace.c [!USE_PROCFS] (trace): Differentiate output format depending

	Print ptrace_setoptions value in debug mode.

2010-11-30  Wang Chao  <wang.chao (a] cn.fujitsu.com>

	Handle followfork using ptrace_setoptions if available
	If PTRACE_O_TRACECLONE et al options are supported by kernel,
	use them to do followfork rather than the original setbpt
	method that changes registers ourselves.

	* defs.h [LINUX] (handle_new_child): New function prototype.
	* process.c [LINUX] (handle_new_child): New function based on the
	code from internal_fork(), with a trivial change: do reparent only
	for sys_clone.
	[LINUX] (internal_fork): Use handle_new_child().  Do nothing if
	ptrace_setoptions is in effect.
	* strace.c [LINUX] (handle_ptrace_event): New function.
	[LINUX] (trace): If ptrace_setoptions is in effect, then
	call the new function to handle PTRACE_EVENT_* status, and
	set PTRACE_SETOPTIONS when we see the initial stop of tracee.

	Test how PTRACE_SETOPTIONS support works
	Currently test fork related options only.  Fork a child that uses
	PTRACE_TRACEME at startup and then does a fork so strace can test
	how the PTRACE_SETOPTIONS support works before it handles any real
	tracee.  Since PTRACE_O_TRACECLONE/*FORK were introduced to kernel
	at the same time, this test seems to be enough for these 3 options.

	* defs.h [LINUX]: Define PTRACE_O_TRACECLONE et al macros here.
	(ptrace_setoptions): New variable declaration.
	* strace.c [LINUX] (test_ptrace_setoptions): New function, tests
	whether kernel supports PTRACE_O_CLONE/*FORK, the result is stored
	in the new variable ptrace_setoptions for later use.
	(main): Call test_ptrace_setoptions() if followfork option is set.

2010-09-17  Dmitry V. Levin  <ldv (a] altlinux.org>

	Enable support for less verbose build rules
	* configure.ac (AM_INIT_AUTOMAKE): Add silent-rules.

2010-09-17  Wang Chao  <wang.chao (a] cn.fujitsu.com>

	Do not trace children cloned with CLONE_UNTRACED flag
	If clone is called with flag CLONE_UNTRACED, to be consistent with
	option PTRACE_O_TRACECLONE, we should not set CLONE_PTRACE flag on
	its arguments.

	* process.c [LINUX] (internal_fork): Check the syscall and arguments.

2010-09-17  Dmitry V. Levin  <ldv (a] altlinux.org>

2010-09-15  Dmitry V. Levin  <ldv (a] altlinux.org>

	Pass less information to qualify_one and qual_*
	* syscall.c (qualify_one, qual_syscall, qual_signal, qual_fault,
	qual_desc): Take just a bitflag argument instead of pointer to the whole
	qual_options structure.
	(struct qual_options): Update prototype of "qualify" field.
	(qualify): Update use of qualify_one and qual_options->qualify.

2010-09-15  Wang Chao  <wang.chao (a] cn.fujitsu.com>

	Fix -e option with only one value in qualifier statement
	Fix regression introduced by commit v4.5.20-19-g30145dd:
	if -e option is used with only one value in qualifier statement,
	e.g. 'strace -e trace=open ls', syscall information would not be
	printed properly.

	* syscall.c (qualify): Remove faulty optimization.

2010-09-15  Mike Frysinger  <vapier (a] gentoo.org>

	Fix off_t/rlim_t size checks when cross-compiling
	The current off_t/rlim_t size checks (wrt size of long long) use AC_RUN
	which obviously doesn't work when cross-compiling.  While we don't hit
	any configure errors, the fall back code is pretty dumb (which is to say
	there isn't any).  Considering the code in question though, we can use
	some fun compiler tricks with sizeof and array lengths to turn it into
	a pure build test and avoid the RUN issue completely.

	* m4/long_long.m4 (AC_OFF_T_IS_LONG_LONG, AC_RLIM_T_IS_LONG_LONG):
	Convert from AC_RUN_IFELSE to AC_COMPILE_IFELSE.

	Fix long long little endian detection when cross-compiling
	The long long endian detection code does an AC_TRY_RUN() and since that
	doesn't work when cross-compiling, it sets a fallback value.  However,
	rather than do any sort of default endian detection, the code simply
	sets it to "no".  This probably breaks most little endian systems out
	there when cross-compiling for them.  It certainly breaks Blackfin
	systems.  So use the common endian detection code provided by autoconf
	and key off of that when cross-compiling.

	* configure.ac: Call AC_C_BIGENDIAN.
	* m4/long_long.m4 (AC_LITTLE_ENDIAN_LONG_LONG): Set cross-compiling
	logic based on ac_cv_c_bigendian.

	Blackfin: decode new syscalls
	* linux/bfin/syscallent.h: Add fanotify/prlimit/cacheflush syscalls.
	* linux/syscall.h: Add sys_cacheflush() decl.
	* system.c: Decode Blackfin's cacheflush syscall.

	* linux/ioctlent.sh: Search a few non-exported paths.

2009-10-12  Mike Frysinger  <vapier (a] gentoo.org>

	sparc/linux: Rewrite to use asm/ptrace.h
	The current sparc/linux code uses asm/reg.h, but recent Linux kernels
	dropped that header completely.  So switch over to the ptrace headers
	as those should stick around indefinitely as part of the ABI.

	Avoid malloc(0) in getdents parsers
	On end of directory, getdents returns 0.  This return value is used to
	then try and do malloc(0), but on some systems this will always return
	NULL.  Since the code won't read the pointer in question if len is 0,
	then don't bother calling malloc(0) and set the pointer to NULL ourself.
