exhausted. - Add a new protect(1) command that can be used to set or revoke protection from arbitrary processes. Similar to ktrace it can apply a change to all existing descendants of a process as well as future descendants. - Add a new procctl(2) system call that provides a generic interface for control operations on processes (as opposed to the debugger-specific operations provided by ptrace(2)). procctl(2) uses a combination of idtype_t and an id to identify the set of processes on which to operate similar to wait6(). - Add a PROC_SPROTECT control operation to manage the protection status of a set of processes. MADV_PROTECT still works for backwards compatability. - Add a p_flag2 to struct proc (and a corresponding ki_flag2 to kinfo_proc) the first bit of which is used to track if P_PROTECT should be inherited by new child processes.

* See i386-fbsd.c for copyright and license terms.
|
|
*
|
|
* System call arguments come in several flavours:
|
|
* Hex -- values that should be printed in hex (addresses)
|
|
* Octal -- Same as above, but octal
|
|
* Int -- normal integer values (file descriptors, for example)
|
|
* Name -- pointer to a NULL-terminated string.
|
|
* BinString -- pointer to an array of chars, printed via strvisx().
|
|
* Ptr -- pointer to some unspecified structure. Just print as hex for now.
|
|
* Stat -- a pointer to a stat buffer. Prints a couple fields.
|
|
* Ioctl -- an ioctl command. Woefully limited.
|
|
* Quad -- a double-word value. e.g., lseek(int, offset_t, int)
|
|
* Signal -- a signal number. Prints the signal name (SIGxxx)
|
|
* Sockaddr -- a pointer to a struct sockaddr. Prints symbolic AF, and IP:Port
|
|
* StringArray -- a pointer to an array of string pointers.
|
|
* Timespec -- a pointer to a struct timespec. Prints both elements.
|
|
* Timeval -- a pointer to a struct timeval. Prints both elements.
|
|
* Timeval2 -- a pointer to two struct timevals. Prints both elements of both.
|
|
* Itimerval -- a pointer to a struct itimerval. Prints all elements.
|
|
* Pollfd -- a pointer to an array of struct pollfd. Prints .fd and .events.
|
|
* Fd_set -- a pointer to an array of fd_set. Prints the fds that are set.
|
|
* Sigaction -- a pointer to a struct sigaction. Prints all elements.
|
|
* Umtx -- a pointer to a struct umtx. Prints the value of owner.
|
|
* Sigset -- a pointer to a sigset_t. Prints the signals that are set.
|
|
* Sigprocmask -- the first argument to sigprocmask(). Prints the name.
|
|
* Kevent -- a pointer to an array of struct kevents. Prints all elements.
|
|
* Pathconf -- the 2nd argument of pathconf().
|
|
*
|
|
* In addition, the pointer types (String, Ptr) may have OUT masked in --
|
|
* this means that the data is set on *return* from the system call -- or
|
|
* IN (meaning that the data is passed *into* the system call).
