===============================================
* Improvements
* Implemented decoding of SCM_TIMESTAMP* control messages.
* Implemented decoding of netlink NLMSG_DONE messages.
* Implemented decoding of netlink generic nlmsg_type and nlmsg_flags.
* Implemented decoding of NETLINK_AUDIT, NETLINK_NETFILTER, NETLINK_ROUTE,
NETLINK_SELINUX, NETLINK_SOCK_DIAG, and NETLINK_XFRM message types.
* Implemented decoding of NETLINK_GENERIC protocol families.
* Implemented basic protocol specific decoding of AF_INET, AF_INET6,
AF_NETLINK, AF_PACKET, AF_SMC, and AF_UNIX messages of NETLINK_SOCK_DIAG.
* Implemented basic decoding of netlink attributes.
* Implemented basic protocol specific decoding of AF_INET, AF_NETLINK,
AF_PACKET, AF_SMC, and AF_UNIX netlink attributes of NETLINK_SOCK_DIAG.
* Implemented decoding of inet_diag_msg, netlink_diag_msg, and unix_diag_msg
netlink attributes of NETLINK_SOCK_DIAG.
* Updated lists of ARPHRD_*, KEYCTL_*, NDIAG_SHOW_*, RTM_*, SCM_*, SCTP_*,
SO_*, V4L2_*, and prctl ARCH_* constants.
* Updated lists of ioctl commands from Linux 4.12.
* Bug fixes
* In interactive mode (-I2), those signals that were blocked at startup
will remain blocked for the whole period of strace execution.
* strace no longer resets SIGCHLD handler in tracees to the default action.
* When traced command is terminated by a blocked signal, strace unblocks
that signal to ensure its own termination with the same signal.
* Fixed corner cases in decoding of old sigaction syscall.
* Fixed build with old kernel headers on mips.
* Fixed build on aarch64 and tile with glibc >= 2.26.
* Fixed build on arc and nios2.
Bug: N/A
Test: strace date

Upgrade strace to 4.17.
Noteworthy changes in release 4.17 (2017-05-24)
===============================================
* Changes in command line syntax
* Syscall classes specified in -e trace= option now have % prefix (like
-e trace=%process). Old style class names without leading % are still
supported, but considered deprecated now.
* Improvements
* Optimized syscall filtering.
* Improved representation of timestamps.
* Enhanced decoding of sched_setattr syscall.
* Added -e trace=%stat option for tracing variants of stat syscall.
* Added -e trace=%lstat option for tracing variants of lstat syscall.
* Added -e trace=%fstat option for tracing variants of fstat and fstatat
syscalls.
* Added -e trace=%%stat option for tracing syscalls used for querying file
status information (stat, lstat, fstat, fstatat, statx, and their
variations).
* Added -e trace=%statfs option for tracing statfs, statfs64 and statvfs
syscalls.
* Added -e trace=%fstatfs option for tracing fstatfs, fstatfs64 and fstatvfs
syscalls.
* Added -e trace=%%statfs option for tracing syscalls used for querying file
system statistics information (statfs-like, fstatfs-like and ustat).
* Added -e trace=/regex option for filtering syscalls using regular
expressions.
* Added support for prepending of question mark before syscall qualification
in -e trace expressions in order to suppress error in case no syscalls
matched the provided qualification.
* Implemented decoding of signal mask in rt_sigreturn syscall on alpha, arc,
arm, avr32, bfin, cris, hppa, m68k, metag, microblaze, mips, nios2, or1k,
powerpc, powerpc64, riscv, sh, sh64, sparc, sparc64, tile, x86, and xtensa
architectures.
* Implemented decoding of statx syscall.
* Implemented decoding of NS_* ioctl commands.
* Implemented decoding of the remaining V4L2_BUF_TYPE_* types.
* Implemented decoding of VIDIOC_[SG]_TUNER ioctl commands.
* Implemented decoding of NLMSG_ERROR netlink messages.
* Improved decoding of BPF_PROG_ATTACH command of bpf syscall.
* Improved decoding of misplaced parts in DM_* ioctl commands.
* Updated lists of ioctl commands from Linux 4.11.
* Bug fixes
* Fixed decoding of flags argument of preadv2 and pwritev2 syscalls on x32.
* Fixed the number of arguments and tracing flags of alpha specific syscalls.
* Fixed decoding of old sigsuspend syscall on alpha, cris, mips, powerpc,
powerpc64, sh, sh64, sparc, and sparc64.
* Fixed decoding of sgetmask and ssetmask syscalls on 64-bit architectures.
* Fixed decoding of netlink messages received within struct msghdr.
* Worked around a bug in miscompiled aarch64 kernels leading to the 3rd
argument of sched_getattr syscall being not quite 32-bit.
* Fixed corner cases of printing inaccessible times argument of utimes
and futimesat syscalls.
Bug: N/A
