* Variant of atomic_t specialized for reference counts.
*
* The interface matches the atomic_t interface (to aid in porting) but only
* provides the few functions one should use for reference counting.
*
* Saturation semantics
* ====================
*
* refcount_t differs from atomic_t in that the counter saturates at
* REFCOUNT_SATURATED and will not move once there. This avoids wrapping the
* counter and causing 'spurious' use-after-free issues. In order to avoid the
* cost associated with introducing cmpxchg() loops into all of the saturating
* operations, we temporarily allow the counter to take on an unchecked value
* and then explicitly set it to REFCOUNT_SATURATED on detecting that underflow
* or overflow has occurred. Although this is racy when multiple threads
* access the refcount concurrently, by placing REFCOUNT_SATURATED roughly
* equidistant from 0 and INT_MAX we minimise the scope for error:
*
* INT_MAX REFCOUNT_SATURATED UINT_MAX
* 0 (0x7fff_ffff) (0xc000_0000) (0xffff_ffff)
* +--------------------------------+----------------+----------------+
* <---------- bad value! ---------->
*
* (in a signed view of the world, the "bad value" range corresponds to
* a negative counter value).
*
* As an example, consider a refcount_inc() operation that causes the counter
* to overflow:
*
* int old = atomic_fetch_add_relaxed(r);
* // old is INT_MAX, refcount now INT_MIN (0x8000_0000)
* if (old < 0)
* atomic_set(r, REFCOUNT_SATURATED);
*
* If another thread also performs a refcount_inc() operation between the two
* atomic operations, then the count will continue to edge closer to 0. If it
* reaches a value of 1 before /any/ of the threads reset it to the saturated
* value, then a concurrent refcount_dec_and_test() may erroneously free the
* underlying object.
* Linux limits the maximum number of tasks to PID_MAX_LIMIT, which is currently
* 0x400000 (and can't easily be raised in the future beyond FUTEX_TID_MASK).
* With the current PID limit, if no batched refcounting operations are used and
* the attacker can't repeatedly trigger kernel oopses in the middle of refcount
* operations, this makes it impossible for a saturated refcount to leave the
* saturation range, even if it is possible for multiple uses of the same
* refcount to nest in the context of a single task:
*
* (UINT_MAX+1-REFCOUNT_SATURATED) / PID_MAX_LIMIT =
* 0x40000000 / 0x400000 = 0x100 = 256
*
* If hundreds of references are added/removed with a single refcounting
* operation, it may potentially be possible to leave the saturation range; but
* given the precise timing details involved with the round-robin scheduling of
* each thread manipulating the refcount and the need to hit the race multiple
* times in succession, there doesn't appear to be a practical avenue of attack
* even if using refcount_add() operations with larger increments.
*
* Memory ordering
* ===============
*
* Memory ordering rules are slightly relaxed wrt regular atomic_t functions
* and provide only what is strictly required for refcounts.
*
* The increments are fully relaxed; these will not provide ordering. The
* rationale is that whatever is used to obtain the object we're increasing the
* reference count on will provide the ordering. For locked data structures,
* its the lock acquire, for RCU/lockless data structures its the dependent
* load.
*
* Do note that inc_not_zero() provides a control dependency which will order
* future stores against the inc, this ensures we'll never modify the object
* if we did not in fact acquire a reference.
*
* The decrements will provide release order, such that all the prior loads and
* stores will be issued before, it also provides a control dependency, which
* will order us against the subsequent free().
*
* The control dependency is against the load of the cmpxchg (ll/sc) that
* succeeded. This means the stores aren't fully ordered, but this is fine
* because the 1->0 transition indicates no concurrency.
*
* Note that the allocator is responsible for ordering things between free()
* and alloc().
*
* The decrements dec_and_test() and sub_and_test() also provide acquire
* ordering on success.
