=============================================

* Changes in behaviour
  * Messages about unknown tracees are now subject to the strace's quietness
    setting (-q/--quiet).

    the following improvements:
    * Ability to use human-readable settings for -I/--interruptible,
      -D/--daemonize options.
    * Ability to silence specific messages using -e quiet/--quiet qualifier
      (an alias for the -q option), including those that couldn't be silenced
      previously (path resolution messages and "superseded by execve").
    * Ability to specify selected fd decoding features using
      -e decode-fds/--decode-fds qualifier (an alias for the -y option).
    * Ability to set precision for the absolute timestamp, relative timestamp,
      and syscall time output (using --absolute-timestamps,
      --relative-timestamps, and --syscall-times options, respectively).
  * Implemented ability to select the set of displayed columns in the call
    summary output (-U/--summary-columns option).
  * Implemented ability to sort on any summary column.
  * Implemented ability to show information about minimum and maximum call
    duration in the call summary output (addresses Debian bug #240945).
  * Implemented printing of PIDs associated with pidfds in -yy mode.

    commands.
  * Enhanced decoding of RTC_VL_READ ioctl command.

    IPPROTO_*, KEY_*, KVM_*, RTM_F_*, SCHED_*, and *_MAGIC constants.
  * Updated lists of ioctl commands from Linux 5.6.

* Bug fixes
  * Fixed build on csky abiv1 architecture.

=============================================

* Improvements
  * Added -e trace=%creds option for tracing syscalls related to process
    credentials.

=============================================

* Improvements
  * Implemented -DD and -DDD options that move strace into a separate
    process group and session, respectively.

  * Enhanced decoding of BPF_MAP_LOOKUP_ELEM bpf syscall command.
  * Implemented PTP_CLOCK_GETCAPS2, PTP_EXTTS_REQUEST2, PTP_PEROUT_REQUEST2,
    PTP_ENABLE_PPS2, and PTP_SYS_OFFSET2 ioctl decoding.
  * Updated lists of BPF_*, CAN_*, KEXEC_*, KVM_*, MADV_*, MSG_*, P_*, PR_*,
    PTP_*, SCTP_*, and V4L2_* constants.
  * Implemented ability to build ARM EABI mpers support using a separate
    compiler on aarch64.
  * Updated lists of ioctl commands from Linux 5.4.
  * Enhanced manual page.

* Bug fixes
  * Fixed -b execve when --seccomp-bpf option is specified.
  * Fixed decoding of BPF_PROG_LOAD bpf syscall command.
  * Fixed build on no-MMU architectures.
  * Fixed build on antique systems that do not provide necessary definitions
    of AUDIT_ARCH_* constants.

  • v5.3

    187016a6 · Prepare for 5.3 release · 
    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.
