* Fixed decoding of mmap2 syscall on s390 when arguments are not available.
* Fixed decoding of kexec_file_load, mprotect, pkey_mprotect, prctl, preadv*,
and pwritev* syscalls on x32.
* Fixed printing of string arguments of getxattr and setxattr syscalls
when -s option is used to limit the printed string size.
* Fixed decoding of ifconf, ifreq, and loop_info structures on non-native
personalities.
* Fixed decoding of SG_* and LOOP_* ioctl commands.
* Fixed build on mips with musl libc.
* Fixed cross-building of ioctlsort.
* Applied minor formatting fixes to the manual page.
Noteworthy changes in release 4.15 (2016-12-14)
* Changes in behavior
* Time stamps are now printed according to ISO 8601.
* Changed output format of val3 parameter of futex FUTEX_WAKE_OP operation.
* The last argument of mincore, sched_getaffinity, and sched_setaffinity
syscalls is now formatted as an array.
* Improvements
* Implemented syscall fault injection (-e fault=... option).
* Implemented decoding of DM_* ioctl commands.
* Implemented decoding of attr parameter of perf_event_open syscall.
* Implemented decoding of pkey_alloc, pkey_free, and pkey_mprotect syscalls.
* Implemented dumping of mq_timedsend and mq_timedreceive syscalls.
* Implemented decoding of PR_SET_FP_MODE and PR_GET_FP_MODE operations
of prctl syscall.
* Implemented PTRACE_GETREGS API support on m68k.
* Updated lists of ARCH_*, BPF_*, BTRFS_*, FALLOC_*, MS_*, *_MAGIC,
and V4L2_* constants.
* Updated lists of ioctl commands from Linux 4.9.
* Added decoding of recently added syscalls on arc, x32, and xtensa.
* Enhanced manual page.
* Bug fixes
* Fixed corner cases in decoding of exit, exit_group, futimesat, getgroups,
getresuid, init_module, inotify_init1, kcmp, kexec_load, lookup_dcookie,
mq_getsetattr, mq_notify, mq_open, mq_timedreceive, mq_timedsend,
name_to_handle_at, prctl, process_vm_readv, process_vm_writev, setfsuid,
setgroups, setns, unshare, and utimes syscalls.
* Fixed handling of verbose flag in printing of controls array
of struct v4l2_ext_controls.
* Fixed omission of field names in the output of capability, sigaction,
sigevent, statfs, timespec, timeval, and utimbuf structures.
* Fixed printing of unknown syscalls in siginfo structure.
* Fixed decoding of ioctl constants on m68k.
* Fixed cris architecture support.
* Fixed cross build when host compiler does not support the same
set of warning flags as the cross compiler.
* Fixed build on SLE10 and SLE11.
