Noteworthy changes in strace 5.3 (2019-09-25)
=============================================

* Improvements
  * Implemented usage of seccomp-bpf for stopping tracees only for filtered
    syscalls.  Use --seccomp-bpf option to enable.
  * Implemented decoding of pidfd_open and clone3 syscalls.
  * Enhanced decoding of io_cancel, io_submit, s390_sthyi, and syslog syscalls.
  * Enhanced decoding of NETLINK_ROUTE protocol.
  * Implemented decoding of UNIX_DIAG_UID netlink attribute.
  * Implemented decoding of WDIOC_* ioctl commands.
  * Enchanced syscall count statistics: overhead is now applied per-call,
    added ability for sorting on errors field.
  * Syscall delay injection and overhead values can now be supplied with
    time measure unit suffix and provided in IEEE 754 floating point format.
  * Updated lists of AUDIT_*, BPF_*, ETH_*, KEYCTL_*, KVM_*, MAP_*, SO_*, TCP_*, V4L2_*,
    XDP_*, and *_MAGIC constants.
  * Updated lists of ioctl commands from Linux 5.3.
  * Enhanced manual page.

* Bug fixes
  * Fixed syscall tampering on arc, avr32, csky, ia64, m68k, metag, mips,
    nios2, or1k, riscv, s390, s390x, sparc, sparc64, and tile architectures
    when PTRACE_GET_SYSCALL_INFO is in use.
  * Fixed decoding of sockaddr_hci (AF_BLUETOOTH) addresses that lack
    hci_channel field.
  * Fixed evdev ioctl bitset decoding.
  * Fixed tests on alpha with Linux kernel headers 5.1+.

* Portability
  * Removed support for decoding syscalls in range [1024...1079] on AArch64
    architecture as this range has never been implemented in mainline kernel
    releases.
