In mips n32 abi, like in most of 32-bit architectures, offset
is passed to preadv/pwritev syscalls using two syscall arguments.
* io.c (print_llu_from_low_high_val) [LINUX_MIPSN32]: Remove.
Rather than trigger an ERROR which fails `make check`, go with SKIP
instead. We don't want the testsuite failing due to kernel bugs.
* tests/ipc_sem.c (main): Change 99 to 77.
The s390 hardware can't support an exact si_addr, and the current kernels
don't handle text addresses correctly at all. Until that improves, skip
the test on s390.
* tests/pc.c (main): Return 77 on s390 systems.
As ioctls_inc.h generated natively on x32 differs both from 32/ioctls_inc.h
(by 45 entries) and from linux/64/ioctls_inc.h (by 322 entries), use x32
specific ioctl entries on x32 personality.
* linux/x32/ioctls_inc0.h: Generate from linux v3.19 using ioctls_gen.sh.
* linux/x86_64/ioctlent2.h: Remove.
* linux/x86_64/ioctls_arch2.h: New file.
* linux/x86_64/ioctls_inc2.h: New file.
* Makefile.am (EXTRA_DIST): Remove linux/x86_64/ioctlent2.h, add
linux/x86_64/ioctls_arch2.h and linux/x86_64/ioctls_inc2.h.
* tests/uid.c (main): Ignore uids returned by getresuid to avoid
16bit vs 32bit issues on big endian architectures.
Change real UID instead of effective UID in setresuid test.
* tests/uid16.c (main): Likewise.
* tests/uid32.c (main): Change real UID instead of effective UID
in setresuid test to match uid.c
* tests/uid.awk: Update setresuid regexp.

If the tools we use call older getdents syscalls where d_type isn't
passed back, or the arch is old (like Alpha) and can't pass back in
either version, make sure we don't fail.
* tests/getdents.awk (d_type_dir, d_type_reg): Accept DT_UNKNOWN.
Fix regression introduced by commit v4.9-9-gc3a5c01.
* signal.c (HAVE_SA_RESTORER): New macro.
[HPPA || IA64]: Do not undefine SA_RESTORER.
(old_sigaction, old_sigaction32, new_sigaction): Use HAVE_SA_RESTORER
instead of SA_RESTORER to check whether to define sa_restorer.
(decode_old_sigaction, decode_new_sigaction): Use HAVE_SA_RESTORER in
addition to SA_RESTORER to check whether to use sa_restorer.
* strace.c (startup_child): Check that the length of the command strace
is going to execute does not exceed PATH_MAX limit.

Restore the order of including <sys/reg.h> and <linux/ptrace.h>
headers that was inadvertently changed by commit v4.9-280-g5503dd2.
This should fix build on platforms like m68k where some constants
are defined simultaneously as enums by <sys/reg.h> and as macros
by <asm/ptrace.h>.
* process.c: Include "ptrace.h" after "regs.h".
* signal.c: Likewise.
* syscall.c: Likewise.
* util.c: Likewise.
As time_t is a 64-bit type in x32 personality, it is not correct to
treat it as a long int type.
* time.c (current_time_t_is_compat): New macro.
(sprinttv, sprint_timespec, printitv_bitness, tprint_timex): Use it.
(tprint_timeval, do_sprinttv, sprint_timespec): Use j and uintmax_t
when printing tv_sec/tv_usec.
(tprint_timex): Use j and intmax_t/uintmax_t when printing struct timex
members of type kernel_long_t.
When running 32bit ipc tests on ppc/sparc with a 64bit kernel, the ipc
logic wrongly returns errors. Detect that and throw an error.
* tests/ipc_sem.c: Return 99 when errno is EFAULT.
* tests/ipc_sem.test: Save output to $OUT and show it when failing.
Handle exit status 99 to throw an ERROR.
For a few linux releases (3.1 through 3.3), this define in the exported
headers were broken. Redefine if that's the case.
* ptrace.h [PTRACE_EVENT_STOP]: Redefine if PTRACE_EVENT_STOP is 7.
When files get updated, the bootstrap script should make sure the
parallel dirs are kept in sync.
* bootstrap: Always generate the test$m. Clean up symlinks first.
Don't link in Makefile.in files.
Use the AX_PROG_CC_FOR_BUILD helper to set up build settings when cross
compiling. This way ioctlsort uses the build tools all the time.
* configure.ac: Call AX_PROG_CC_FOR_BUILD.
* Makefile.am (ioctlsort_CC): Set to CC_FOR_BUILD.
(ioctlsort_CPPFLAGS): Change CPPFLAGS to CPPFLAGS_FOR_BUILD.
(ioctlsort_CFLAGS): Change CFLAGS to CFLAGS_FOR_BUILD.
(ioctlsort_LDFLAGS): Change LDFLAGS to LDFLAGS_FOR_BUILD.
(ioctlsort_LD): Delete.
(ioctlsort%): Change to ioctlsort%$(BUILD_EXEEXT). Use ioctlsort_CFLAGS.
* m4/ax_prog_cc_for_build.m4: Import from the autoconf-archive package.
* configure.ac: Check for dladdr in -ldl.
* tests/Makefile.am (pc_LDADD): Adde $(dl_LIBS).
* tests/pc.c: Include "config.h" and <dlfcn.h>.
(main): Use dladdr to find the address to unmap.
As an exception to the general rules that syscall names should match
__NR_* constants defined in kernel headers, show select as "select"
and old select as "oldselect".
* linux/arm/syscallent.h (82): Change name to oldselect.
* linux/hppa/syscallent.h (142): Change name to select.
* linux/mips/syscallent-n32.h (6022): Likewise.
* linux/mips/syscallent-n64.h (5022): Likewise.
* linux/mips/syscallent-o32.h (4142): Likewise.
* linux/sparc/syscallent.h (230): Likewise.
* linux/s390/syscallent.h (1, 180, 181): Change syscall names to match
__NR_* constants defined in arch/s390/include/uapi/asm/unistd.h.
* linux/s390x/syscallent.h: Likewise.
When there were fewer xlat headers, this didn't matter as much.
But now with >200, trying to run them all in parallel can easily
fork bomb smaller systems.
* xlat/gen.sh (main): Do not more jobs than # of cpus.
* linux/hppa/syscallent.h (18, 28, 59, 84, 108, 109, 280):
Change syscall names to match __NR_* constants defined in
arch/parisc/include/uapi/asm/unistd.h.
The parisc kernel has some legacy baggage here and decodes the 64bit
field in the reverse order. Handle it in strace too.
* fanotify.c [HPPA] (sys_fanotify_mark): Reverse the mask bits.
Looks like the similarity of these names caused confusion when generating
the syscall table. getresgid was wired to the wrong output while the other
two were wired up to printargs instead of the real printer.
* linux/ia64/syscallent.h: Connect getresuid to sys_getresuid, getresgid to
sys_getresgid, and setresgid to sys_setresgid.
The ia64 port pulls in the i386 syscall table so it can decode
32bit apps, so we need to enable the 16bit uid parsers for it.
* defs.h (NEED_UID16_PARSERS): Define to 1 for IA64.
* linux/ia64/syscallent.h: Undefine sys_stime to avoid redefine warnings.
There is no guarantee that the backing value for the various time fields
are ints or longs which makes printfs annoying. Lets cast them to the
uintmax_t type so we can use the j flag and not worry about truncation.
* v4l2.c (v4l2_ioctl): Use j and uintmax_t when printing tv_sec/tv_usec.
Assume that the kernel is v2.5.46 or newer, i.e. PTRACE_SETOPTIONS
and PTRACE_O_TRACESYSGOOD|PTRACE_O_TRACEEXEC|PTRACE_O_TRACECLONE
are universally available.
This change removes all code that implemented post-execve SIGTRAP
handling and fork/vfork/clone->CLONE_PTRACE substitution.
* defs.h (TCB_BPTSET, TCB_WAITEXECVE): Remove macros.
(need_fork_exec_workarounds, setbpt, clearbpt): Remove declarations.
* strace.c (need_fork_exec_workarounds,
test_ptrace_setoptions_followfork, test_ptrace_setoptions_for_all):
Remove.
(syscall_trap_sig): Set to (SIGTRAP | 0x80).
(ptrace_setoptions): Set to (PTRACE_O_TRACESYSGOOD | PTRACE_O_TRACEEXEC).
(detach): Do not test for TCB_BPTSET.
(init): Do not call test_ptrace_setoptions_followfork and
test_ptrace_setoptions_for_all. Do not test for TCB_BPTSET.
* syscall.c (syscall_fixup_on_sysenter, internal_fork, internal_exec,
syscall_fixup_for_fork_exec, syscall_fixup_on_sysexit): Remove.
(trace_syscall_entering): Do not test for TCB_WAITEXECVE. Do not call
syscall_fixup_on_sysenter and syscall_fixup_for_fork_exec.
(trace_syscall_exiting): Do not call syscall_fixup_on_sysexit and
syscall_fixup_for_fork_exec.
[IA64] (ia64_ia32mode): Make static.
* linux/ia64/arch_regs.h (ia64_ia32mode): Remove declaration.
* util.c: Do not include "syscall.h".
(arg_setup, get_arg0, get_arg1, set_arg0, set_arg1, restore_arg0,
restore_arg1, arg_finish_change, change_syscall, setbpt, clearbpt):
Remove.
* tests/ptrace_setoptions.test: Remove.
* tests/Makefile.am (TESTS): Remove it.
* tests/pc.c (main): Unmap larger memory region.
Dump process map for debug purposes.
* tests/pc.test: Update regexps to take CLD_DUMPED child process
into account.
