src/tests/kernel: t_ptrace_wait.c
Log Message:
Mark syscall1 broken in t_ptrace_wait*
Mark this test broken with kern/52012 as the tracee does not stop on syscall
entry. Check for siginfo(2) in syscall1 and unveil two new bugs.
PR kern/52012: PT_SYSCALL does not stop on syscall entry
PR kern/52018: ptrace(2) PT_SYSCALL generates SIGTRAP without si_code
PR kern/52019: ptrace(2) PT_SYSCALL generate SIGTRAP to the parent but
returns SIGSTOP in PT_GET_SIGINFO
