Add or correct range checking of signal numbers in system calls and ioctls.

PT_{GET|SET}DDREGS are defined in i386 MD headers in STABLE.

operations and kern_ptrace implementation function. This is required for an upcoming Linux/i386 emulator ptrace syscall.

Prevent DoS: Do not allow one to trace an ancestor when one is being traced.

nasty interfaces should have been put to death long ago. Nothing in the tree uses them (and should not anyway since we have PT_GETREGS etc) and as near as I can tell, no ports use it either.

Introduce the new function

p_trespass(struct proc *p1, struct proc *p2) which returns zero or an errno depending on the legality of p1 trespassing on p2. Replace kern_sig.c:CANSIGNAL() with call to p_trespass() and one extra signal related check. Replace procfs.h:CHECKIO() macros with calls to p_trespass(). Only show command lines to process which can trespass on the target process.

useracc() the prequel:

Merge the contents (less some trivial bordering the silly comments) of and into . This puts the #defines for the vm_inherit_t and vm_prot_t types next to their typedefs. This paves the road for the commit to follow shortly: change useracc() to use VM_PROT_{READ|WRITE} rather than B_{READ|WRITE} as argument.
