NEWS for strace version 4.22

• Changes in infrastructure

  • The mailing list was moved to strace-devel@lists.strace.io.
  • SourceForge git repository
    (https://sourceforge.net/p/strace/code/ci/master/tree/) is no longer
    maintained. Please use GitLab (https://gitlab.com/strace/strace/)
    or GitHub (https://github.com/strace/strace/) repository instead.

• Changes in behaviour

  • When printing string data, '8' and '9' following an octal escape sequence
    no longer lead to unabbreviated octal escape sequence output, as they used
    to do.
  • Angle brackets are now printed as octal number escape sequences
    in the output of paths associated with file descriptors.
  • Data dump for write syscalls (-e write) is performed regardless
    of successfulness of these syscall (addresses Debian bug #436284).
  • -r and -t options are now affect output independently. Previously,
    -r option led to ignoring of the -t option (addresses Debian bug #466195).

• Improvements

  • Implemented delay injection (-e inject=SET:delay_enter= and
    -e inject=SET:delay_exit= options).
  • Added -A option for opening output files in append mode
    (addresses Debian bug #528488).
  • IPv6 addresses shown in socket information in -yy mode are now printed
    in brackets.
  • Enhanced decoding of bpf, prctl and ptrace syscalls.
  • Enhanced decoding of BTRFS_IOC_INO_PATHS, BTRFS_IOC_LOGICAL_INO, and PTP_*
    ioctl commands.
  • Enhanced NETLINK_ROUTE protocol decoding.
  • Updated lists of signal codes.
  • Updated lists of BPF_*, BTN_*, ETH_P_*, INET_DIAG_BC_*, KEY_*, POLL*, RWF_*,
    SCHED_FLAG_*, SCTP_* and error constants.
  • Implemented block/character device number printing in -yy mode.
  • Known pixel/SDR format names are printed as comments for pixelformat fields
    in v4l2 structures.
  • Enhanced decoding of kern_features syscall.
  • Enhanced NETLINK_NETFILTER netlink protocol decoder.
  • Optimized handling of large number of tracees.
  • Improved wall clock time measurement in syscall count statistics
    (-c -w option).
  • Extended the range of allowed values in -e inject=...:retval= expression.
  • Added i18n support.
  • Updated lists of ioctl commands from Linux 4.16.
  • Enhanced manual page.

• Bug fixes

  • Fixed build on m68k.
  • Fixed v4l2 pixelformat decoding on big-endian architectures.
  • Fixed -O option.
