Hi all! I'm writing a kernel module that needs to check if the current process is attached (via ptrace) to some other process. So I do something like this:
... // verify pid p = find_vpid(child_pid); if ( p == NULL ) ... // get the task task = pid_task(p, PIDTYPE_PID); if ( task == NULL ) .. // check ptrace privs int ret = cap_ptrace_access_check(task, PTRACE_MODE_READ); When compiling it generates an error: WARNING: "cap_ptrace_access_check" [$PATH/$MOD.ko] undefined! I tried with ptrace_access_check, ptrace_may_check, security_ptrace_access_check, ptrace_may_access, etc... but none of them works for me. I'm building the module against a 2.6.35 kernel. Any idea about what am I doing wrong? Thanks in advance! Joxean Koret
