- Update to strace 5.6
* Changes in behaviour
* Messages about unknown tracees are now subject to the strace's quietness
setting (-q/--quiet).
* If -A option is provided without -o, or -S option without -c/-C, a warning
about its uselessness is printed now.
* The usage of --seccomp-bpf without -f has no effect now.
* Improvements
* Every short option now has a long option alias, which also has enabled
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previously (path resolution messages and "superseded by execve").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.
* Implemented PTRACE_GETREGS API support on hppa, sh, sh64, and xtensa.
* Improved performance of libdw-based stack traces printing by implementing
a symbol-to-address cache.
* Implemented decoding of openat2 and pidfd_getfd syscalls. (forwarded request 791997 from Andreas_Schwab)
