Such a check is done on the "data" argument to ptrace() if the "request" argument is PTRACE_SETOPTIONS. However, according to ptrace(2) (and, indeed, according to the gdb sources and the kernel sources), the PTRACE_SETOPTIONS request accepts a bitmask of PTRACE_O_* values as its "data" argument, *not* a pointer. -- Summary: sysdeps/unix/sysv/linux/ptrace.c PTRACE_SETOPTIONS inappropriate pointer check Product: glibc Version: unspecified Status: NEW Severity: minor Priority: P2 Component: libc AssignedTo: drepper at redhat dot com ReportedBy: chris2k01 at hotmail dot com CC: glibc-bugs at sources dot redhat dot com http://sourceware.org/bugzilla/show_bug.cgi?id=11100 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ^ permalink raw reply [flat|nested] 3+ messages in thread
