|
|
===============================================
|
|
|
|
* Changes in behavior
|
|
* Some syscalls have different names depending on architecture and
|
|
personality. In these cases, syscall filtering and printing now
|
|
consistently uses the names that match corresponding __NR_* kernel
|
|
macros of the tracee's architecture and personality.
|
|
* Added strace prefix to all diagnostic messages.
|
|
|
|
* Improvements
|
|
* Enhanced and extended test suite.
|
|
* Implemented reliable tracing of processes whose personality differs
|
|
from the personality of strace, fixed decoding of 32-bit personality
|
|
syscalls on 64-bit architectures.
|
|
* When some data referenced by syscall arguments is irrelevant or cannot
|
|
be read from tracee's memory, strace now prints its address consistently.
|
|
* When a syscall is restarted using restart_syscall mechanism, strace now
|
|
shows the syscall name on architectures that expose this information.
|
|
* Print values returned by epoll_create1, eventfd, eventfd2, fanotify_init,
|
|
inotify_init1, perf_event_open, pipe, pipe2, signalfd, signalfd4, socket,
|
|
socketpair, timerfd, and timerfd_create syscalls, as well as F_DUPFD and
|
|
F_DUPFD_CLOEXEC fcntl commands, as file descriptors.

|
and v4l2 ioctl syscall arguments.

|
|
getdents64, getsockopt, io_*, mount, msgctl, prctl, quotactl, recvfrom,
|
|
sendfile, setsockopt, and shmctl syscalls.
|
|
* Implemented decoding of bpf, execveat, ioperm, iopl, kcmp, kexec_file_load,
|
|
lookup_dcookie, membarrier, memfd_create, mlock2, name_to_handle_at,
|
|
open_by_handle_at, sched_getattr, sched_setattr, and userfaultfd syscalls.

Noteworthy changes in release 4.5.19 (2009-10-21)
|
|
=================================================
|
|
|
|
* Changes in behavior
|
|
* When command exits, strace now exits with the same exit status.
|
|
If command is terminated by a signal, strace terminates itself
|
|
with the same signal, so that strace can be used as a wrapper
|
|
process transparent to the invoking parent process.
|
|
When using -p option, the exit status of strace is zero unless
|
|
there was an unexpected error in doing the tracing.
