strace: update 4.10 -> 4.11

Noteworthy changes in release 4.11 (2015-12-21)
===============================================

* Changes in behavior
  * Some syscalls have different names depending on architecture and
    personality.  In these cases, syscall filtering and printing now
    consistently uses the names that match corresponding __NR_* kernel
    macros of the tracee's architecture and personality.
  * Added strace prefix to all diagnostic messages.

* Improvements
  * Enhanced and extended test suite.
  * Implemented reliable tracing of processes whose personality differs
    from the personality of strace, fixed decoding of 32-bit personality
    syscalls on 64-bit architectures.
  * When some data referenced by syscall arguments is irrelevant or cannot
    be read from tracee's memory, strace now prints its address consistently.
  * When a syscall is restarted using restart_syscall mechanism, strace now
    shows the syscall name on architectures that expose this information.
  * Print values returned by epoll_create1, eventfd, eventfd2, fanotify_init,
    inotify_init1, perf_event_open, pipe, pipe2, signalfd, signalfd4, socket,
    socketpair, timerfd, and timerfd_create syscalls, as well as F_DUPFD and
    F_DUPFD_CLOEXEC fcntl commands, as file descriptors.
  * Optimized decoding of indirect socket syscalls.
  * Implemented decoding of nanoseconds along with seconds in stat family
    syscalls (addresses Fedora bug #1251176).
  * Implemented decoding of struct statfs.f_flags in statfs syscall.
  * Implemented decoding of siginfo_t.si_syscall and siginfo_t.si_arch
    in SIGSYS signal.
  * Implemented decoding of indirect syscall on mips o32.
  * Implemented decoding of IPPROTO_IP control messages.
  * Implemented decoding of setsockopt syscall multicast arguments.
  * Enhanced decoding of struct sigevent.
  * Enhanced decoding of block, loop, mtd, ptp, rtc, SG_IO, socket, tty,
    and v4l2 ioctl syscall arguments.
  * Enhanced decoding of epoll_create, fcntl, fcntl64, futex, getdents,
    getdents64, getsockopt, io_*, mount, msgctl, prctl, quotactl, recvfrom,
    sendfile, setsockopt, and shmctl syscalls.
  * Implemented decoding of bpf, execveat, ioperm, iopl, kcmp, kexec_file_load,
    lookup_dcookie, membarrier, memfd_create, mlock2, name_to_handle_at,
    open_by_handle_at, sched_getattr, sched_setattr, and userfaultfd syscalls.
  * Updated lists of AF_*, EPOLL_*, FALLOC_FL_*, F_*, INPUT_PROP_*, IPPROTO_*,
    IPV6_*, IP_*, KEY_*, LOCK_*, MNT_*, MS_*, PACKET_*, PERF_FLAG_*, PF_*,
    PR_*, PTRACE_O_*, RENAME_*, SCTP_*, SECBIT_*, SO_*, TCP_*, and siginfo_t
    constants.
  * Added Nios II architecture support.
  * Added new syscall entries to match Linux 4.4.

* Bug fixes
  * Fixed potential short read of strings from tracee's memory.
  * Fixed -qq option in conjunction with -o option.
  * Fixed filtering of <unavailable> syscalls.
  * Fixed decoding of ioctl syscall command on aarch64 and 32-bit architectures
    with 64-bit aligned structures.
  * Fixed decoding of eventfd2, epoll_create1, signalfd4, and sync_file_range2
    syscall flags arguments.
  * Fixed decoding of 4th argument of clock_nanosleep syscall.
  * Fixed decoding of getpagesize syscall on m68k.
  * Fixed decoding of getrandom and seccomp syscalls on aarch64.
  * Fixed decoding of timezone argument of gettimeofday and settimeofday
  * syscalls.
  * Fixed decoding of offset argument of mmap2 syscall on arm, sparc,
    and sparc64.
  * Fixed decoding of pipe syscall on alpha and mips.
  * Fixed decoding of pipe2 syscall on ia64, sh, sparc, and sparc64.
  * Fixed decoding of signal mask argument of pselect6 syscall on x32.
  * Fixed decoding of signal mask of rt_sigreturn syscall on aarch64, m68k,
    and x32.
  * Fixed decoding of 4th argument of semctl indirect syscall.
  * Fixed decoding of sa_restorer and sa_mask of sigaction syscall on m68k.
  * Fixed decoding of statfs64 and fstatfs64 syscalls on arm eabi.
  * Fixed decoding of struct dirent on x32.
  * Fixed decoding of times syscall return value on mips n32 and x32.
  * Fixed decoding of path argument of umount2 syscall
    (addresses Debian bug #785050).
  * Worked around a kernel bug in tracing privileged executables.
  * Fixed various errors in mapping between syscall numbers and associated
    information like the number of syscall arguments, the name of syscall,
    and syscall decoder.

+Subject: [PATCH] mpers.m4: more robust test for -m32/-mx32 compile support
+
+When using the default OE toolchain for x86-64, the basic checks for
+-m32 and -mx32 compile support in mpers.m4 pass but later attempts to
+actually use the toolchain with -m32 fail, e.g.
+
+ | In file included from /home/andre/build/tmp/sysroots/qemux86-64/usr/include/sys/syscall.h:31:0,
+ |                  from ../strace-4.11/defs.h:55,
+ |                  from mpers-m32/kernel_dirent.c:32:
+ | /home/andre/build/tmp/sysroots/qemux86-64/usr/include/bits/syscall.h:41:29: fatal error: bits/syscall-32.h: No such file or directory
+
+Make the mpers.m4 tests more robust so that configure correctly
+detects the limitations of the OE toolchain.
