* 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.
* tests/getdents.out: New file.
* tests/Makefile.am (EXTRA_DIST): Add it.
* tests/getdents.test: Check whether awk is capable of matching long
regular expressions.
On some platforms printing of __s64 types with "%lld" format,
or __u64 types with "%llu" or "%llx" formats causes a warning
that __s64/__u64 type is not compatible with long long format.
From my PoV, this is nonsense, but the workaround costs nothing.
* scsi.c (print_sg_io_v4_req, print_sg_io_v4_res): Cast __u64 types
to (unsigned long long).
* v4l2.c (v4l2_ioctl): Likewise. Cast __s64 type to (long long).
On x86_64/x32, sys_sigreturn is defined only for i386 personality.
* signal.c (sys_sigreturn): Define for X32.
(sys_sigreturn) [X86_64 || X32]: Implement for i386 personality only.
* configure.ac: Check whether struct input_absinfo.resolution is defined
in <linux/input.h>.
* evdev.c (SYN_MAX): Add fallback definition.
(abs_ioctl): Wrap use of struct input_absinfo.resolution in #ifdef check.
(keycode_V2_ioctl, mtslots_ioctl, repeat_ioctl): Wrap in #ifdef checks.
(evdev_read_ioctl): Wrap in #ifdef checks the code that uses EV_SW,
EVIOCGREP, EVIOCGKEYCODE_V2, EVIOCGMTSLOTS, EVIOCGPROP, and EVIOCGSW.
(evdev_write_ioctl): Wrap in #ifdef checks the code that uses EVIOCSREP,
EVIOCSKEYCODE_V2, EVIOCSCLOCKID, and EVIOCREVOKE.
This patch introduces decoding for evdev ioctls. For EVIOCSFF the five
first members are decoded, the union is not. The code was compiled and
tested on x86_64 with Linux 3.13.
* evdev.c: New file.
* Makefile.am (strace_SOURCES): Add it.
* defs.h (evdev_ioctl): New prototype.
* ioctl.c (ioctl_decode): Call evdev_ioctl for 'E' ioctl commands.

macros.

Linux kernel used to guarantee that the largest errno value will not
exceed 4095, but SECCOMP_RET_ERRNO support introduced by kernel commit
v3.4-rc2-13-gacf3b2c71ed20c53dc69826683417703c2a88059 inadvertently
broke it. The guarantee is back with kernel commit
v3.19-8275-g580c57f1076872ebc2427f898b927944ce170f2d.
* syscall.c (is_negated_errno): Set maximum errno value to 4095.
Considering we're requiring linux-2.6 era kernels, the discussion of
header troubles that plagued 2.2 and 2.4 are no longer relevant.
* README-linux: Delete.
* configure.ac (AC_CHECK_HEADERS): Add linux/securebits.h.
* prctl.c (sys_prctl): Implement full decoding of all PR_* constants
as defined in linux v3.19.
