Move post-execve SIGTRAP check from get_scno_on_sysenter (multitude of places on many architectures) to a single location in trace_syscall_entering. This loosens the logic for some arches, since many of them had additional checks such as scno == 0. However, on non-ancient Linux kernels we should never have post-execve SIGTRAP in the first place, by virtue of using PTRACE_O_TRACEEXEC. * syscall.c (get_scno_on_sysenter): Remove tcp->flags & TCB_WAITEXECVE checks. (trace_syscall_entering): Do tcp->flags & TCB_WAITEXECVE check here. (get_scno_on_sysexit): Tweak comment. (syscall_fixup): Likewise. (trace_syscall_exiting): Likewise.

This is strace 4.0, a system call tracer for SunOS 4.x, Linux, System V release 4, Solaris 2.x and Irix 5.x. strace is released under a Berkeley-style license at the request of Paul Kranenburg; see the file COPYRIGHT for details. Read the INSTALL file for generic instructions on how to install strace. If configure cannot guess your system configuration, you can specify it on the command line after the other options like this: ./configure --prefix=/usr i486-linux A single sunos4.1 binary should work on all the sun4, sun4c and sun4m kernel architectures. Let me know if sun4d doesn't work. Other i486-*-sysv4 systems may work with little or no tweaking. See the file NEWS for information on what has changed in recent versions. See the file PORTING if you like strace but it doesn't work on an operating system you use frequently. See the file CREDITS to see who has contributed to strace. See the file TODO if you feel like helping out. You can get the latest version of strace from its homepage at http://sourceforge.net/projects/strace/ . Please send bug reports and enhancements to the strace mailinglist at strace-devel@lists.sourceforge.net, or directly to Wichert Akkerman <wakkerma@debian.org>
