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.

non-asm entries.

* linux/s390/ioctlent.h: Rename to linux/s390/ioctlent.h.in, remove
non-asm entries.

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

[LINUX] (internal_fork): Use handle_new_child(). Do nothing if
ptrace_setoptions is in effect.

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.

2010-09-15 Wang Chao <wang.chao@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.

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.

strace could not terminate normally.

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.
* file.c (sys_getdents, sys_getdents64): Avoid malloc(0) call.

Add accept4 socketcall

Replace x86-64 paccept with accept4
This patch changes the paccept syscall to accept4 for x86-64, since
the former was dropped in Linux kernel commit v2.6.27-rc7-14-g2d4c826.
At the same time, it adds support for pretty printing its arguments.
* linux/x86_64/syscallent.h: Replace paccept with accept4,
hook in sys_accept4.
