Andrew Morgan 72c2d5823f V3 file capabilities: alter behavior of cap_setpcap 
The non-filesystem capability meaning of CAP_SETPCAP is that a process, p1,
can change the capabilities of another process, p2.  This is not the
meaning that was intended for this capability at all, and this
implementation came about purely because, without filesystem capabilities,
there was no way to use capabilities without one process bestowing them on
another.

Since we now have a filesystem support for capabilities we can fix the
implementation of CAP_SETPCAP.

The most significant thing about this change is that, with it in effect, no
process can set the capabilities of another process.

The capabilities of a program are set via the capability convolution
rules:

   pI(post-exec) = pI(pre-exec)
   pP(post-exec) = (X(aka cap_bset) & fP) | (pI(post-exec) & fI)
   pE(post-exec) = fE ? pP(post-exec) : 0

at exec() time.  As such, the only influence the pre-exec() program can
have on the post-exec() program's capabilities are through the pI
capability set.

The correct implementation for CAP_SETPCAP (and that enabled by this patch)
is that it can be used to add extra pI capabilities to the current process
- to be picked up by subsequent exec()s when the above convolution rules
are applied.

Here is how it works:

Let's say we have a process, p. It has capability sets, pE, pP and pI.
Generally, p, can change the value of its own pI to pI' where

   (pI' & ~pI) & ~pP = 0.

That is, the only new things in pI' that were not present in pI need to
be present in pP.

The role of CAP_SETPCAP is basically to permit changes to pI beyond
the above:

   if (pE & CAP_SETPCAP) {
      pI' = anything; /* ie., even (pI' & ~pI) & ~pP != 0  */
   }

This capability is useful for things like login, which (say, via
pam_cap) might want to raise certain inheritable capabilities for use
by the children of the logged-in user's shell, but those capabilities
are not useful to or needed by the login program itself.

One such use might be to limit who can run ping. You set the
capabilities of the 'ping' program to be "= cap_net_raw+i", and then
only shells that have (pI & CAP_NET_RAW) will be able to run
it. Without CAP_SETPCAP implemented as described above, login(pam_cap)
would have to also have (pP & CAP_NET_RAW) in order to raise this
capability and pass it on through the inheritable set.
