* This function determines how parameters are "inherited" from one structure
* to another. There are several different ways this can happen.
*
* 1. If a child structure needs to have its values initialized from a parent
* they are simply copied across. For example SSL_CTX copied to SSL.
* 2. If the structure should take on values only if they are currently unset.
* For example the values in an SSL structure will take appropriate value
* for SSL servers or clients but only if the application has not set new
* ones.
*
* The "inh_flags" field determines how this function behaves.
*
* Normally any values which are set in the default are not copied from the
* destination and verify flags are ORed together.
*
* If X509_VP_FLAG_DEFAULT is set then anything set in the source is copied
* to the destination. Effectively the values in "to" become default values
* which will be used only if nothing new is set in "from".
*
* If X509_VP_FLAG_OVERWRITE is set then all value are copied across whether
* they are set or not. Flags is still Ored though.
*
* If X509_VP_FLAG_RESET_FLAGS is set then the flags value is copied instead
* of ORed.
*
* If X509_VP_FLAG_LOCKED is set then no values are copied.
*
* If X509_VP_FLAG_ONCE is set then the current inh_flags setting is zeroed
* after the next call.

/*
* Win32, before Vista, did not have an OS-provided condition variable
* construct. This leads to the need to construct our own condition variable
* construct in order to support Windows XP.
*
* It is difficult to construct a condition variable construct using the
* OS-provided primitives in a way that is both correct (avoiding race
* conditions where broadcasts get lost) and fair.
*
* CORRECTNESS:
* A blocked thread is a thread which is calling wait(), between the
* precise instants at which the external mutex passed to wait() is
* unlocked and the instant at which it is relocked.
*
* a)
* - If broadcast() is called, ALL blocked threads MUST be unblocked.
* - If signal() is called, at least one blocked thread MUST be unblocked.
*
* (i.e.: a signal or broadcast must never get 'lost')
*
* b)
* - If broadcast() or signal() is called, this must not cause a thread
* which is not blocked to return immediately from a subsequent
* call to wait().
*
* FAIRNESS:
* If broadcast() is called at time T1, all blocked threads must be unblocked
* before any thread which subsequently calls wait() at time T2 > T1 is
* unblocked.
*
* An example of an implementation which lacks fairness is as follows:
*
* t1 enters wait()
* t2 enters wait()
*
* tZ calls broadcast()
*
* t1 exits wait()
* t1 enters wait()
*
* tZ calls broadcast()
*
* t1 exits wait()
*
* IMPLEMENTATION:
*
* The most suitable primitives available to us in Windows XP are semaphores,
* auto-reset events and manual-reset events. A solution based on semaphores
* is chosen.
*
* PROBLEM. Designing a solution based on semaphores is non-trivial because,
* while it is easy to track the number of waiters in an interlocked data
* structure and then add that number to the semaphore, this does not
* guarantee fairness or correctness. Consider the following situation:
*
* - t1 enters wait(), adding 1 to the wait counter & blocks on the semaphore
* - t2 enters wait(), adding 1 to the wait counter & blocks on the semaphore
* - tZ calls broadcast(), finds the wait counter is 2, adds 2 to the semaphore
*
* - t1 exits wait()
* - t1 immediately reenters wait() and blocks on the semaphore
* - The semaphore is still positive due to also having been signalled
* for t2, therefore it is decremented
* - t1 exits wait() immediately; t2 is never woken
*
* GENERATION COUNTERS. One naive solution to this is to use a generation
* counter. Each broadcast() invocation increments a generation counter. If
* the generation counter has not changed during a semaphore wait operation
* inside wait(), this indicates that no broadcast() call has been made in
* the meantime; therefore, the successful semaphore decrement must have
* 'stolen' a wakeup from another thread which was waiting to wakeup from the
* prior broadcast() call but which had not yet had a chance to do so. The
* semaphore can then be reincremented and the wait() operation repeated.
*
* However, this suffers from the obvious problem that without OS guarantees
* as to how semaphore readiness events are distributed amongst threads,
* there is no particular guarantee that the semaphore readiness event will
* not be immediately redistributed back to the same thread t1.
*
* SOLUTION. A solution is chosen as follows. In its initial state, a
* condition variable can accept waiters, who wait for the semaphore
* normally. However, once broadcast() is called, the condition
* variable becomes 'closed'. Any existing blocked threads are unblocked,
* but any new calls to wait() will instead enter a blocking pre-wait stage.
* Pre-wait threads are not considered to be waiting (and the external
* mutex remains held). A call to wait() in pre-wait cannot progress
* to waiting until all threads due to be unblocked by the prior broadcast()
* call have returned and had a chance to execute.
*
* This pre-wait does not affect a thread if it does not call wait()
* again until after all threads have had a chance to execute.
*
* RESOURCE USAGE. Aside from an allocation for the condition variable
* structure, this solution uses two Win32 semaphores.
*
* FUTURE OPTIMISATIONS:
*
* An optimised multi-generation implementation is possible at the cost of
* higher Win32 resource usage. Multiple 'buckets' could be defined, with
* usage rotating between buckets internally as buckets become closed.
* This would avoid the need for the prewait in more cases, depending
* on intensity of usage.

* This computes w := S * w ^ -1 + c, where c = {01100011}.
* Instead of using GF(2^8) mod (x^8+x^4+x^3+x+1} we do the inversion
* in GF(GF(GF(2^2)^2)^2) mod (X^2+X+8)
* and GF(GF(2^2)^2) mod (X^2+X+2)
* and GF(2^2) mod (X^2+X+1)
* The first part of the algorithm below transfers the coordinates
* {0x01,0x02,0x04,0x08,0x10,0x20,0x40,0x80} =>
* {1,Y,Y^2,Y^3,Y^4,Y^5,Y^6,Y^7} with Y=0x41:
* {0x01,0x41,0x66,0x6c,0x56,0x9a,0x58,0xc4}
* The last part undoes the coordinate transfer and the final affine
* transformation S:
* b[i] = b[i] + b[(i+4)%8] + b[(i+5)%8] + b[(i+6)%8] + b[(i+7)%8] + c[i]
* in one step.
* The multiplication in GF(2^2^2^2) is done in ordinary coords:
* A = (a0*1 + a1*x^4)
* B = (b0*1 + b1*x^4)
* AB = ((a0*b0 + 8*a1*b1)*1 + (a1*b0 + (a0+a1)*b1)*x^4)
* When A = (a0,a1) is given we want to solve AB = 1:
* (a) 1 = a0*b0 + 8*a1*b1
* (b) 0 = a1*b0 + (a0+a1)*b1
* => multiply (a) by a1 and (b) by a0
* (c) a1 = a1*a0*b0 + (8*a1*a1)*b1
* (d) 0 = a1*a0*b0 + (a0*a0+a1*a0)*b1
* => add (c) + (d)
* (e) a1 = (a0*a0 + a1*a0 + 8*a1*a1)*b1
* => therefore
* b1 = (a0*a0 + a1*a0 + 8*a1*a1)^-1 * a1
* => and adding (a1*b0) to (b) we get
* (f) a1*b0 = (a0+a1)*b1
* => therefore
* b0 = (a0*a0 + a1*a0 + 8*a1*a1)^-1 * (a0+a1)
* Note this formula also works for the case
* (a0+a1)*a0 + 8*a1*a1 = 0
* if the inverse element for 0^-1 is mapped to 0.
* Repeat the same for GF(2^2^2) and GF(2^2).
* We get the following algorithm:
* inv8(a0,a1):
* x0 = a0^a1
* [y0,y1] = mul4([x0,a1],[a0,a1]); (*)
* y1 = mul4(8,y1);
* t = inv4(y0^y1);
* [b0,b1] = mul4([x0,a1],[t,t]); (*)
* return [b0,b1];
* The non-linear multiplies (*) can be done in parallel at no extra cost.

* NOTE: TABLE_BITS and all non-4bit implementations have been removed in 3.1.

* Even though permitted values for TABLE_BITS are 8, 4 and 1, it should

* TABLE_BITS>1 are lookup-table-driven implementations referred to as
* "Shoup's" in GCM specification. In other words OpenSSL does not cover
* whole spectrum of possible table driven implementations. Why? In
* non-"Shoup's" case memory access pattern is segmented in such manner,
* that it's trivial to see that cache timing information can reveal
* fair portion of intermediate hash value. Given that ciphertext is
* always available to attacker, it's possible for him to attempt to
* deduce secret parameter H and if successful, tamper with messages
* [which is nothing but trivial in CTR mode]. In "Shoup's" case it's
* not as trivial, but there is no reason to believe that it's resistant
* to cache-timing attack. And the thing about "8-bit" implementation is
* that it consumes 16 (sixteen) times more memory, 4KB per individual
* key + 1KB shared. Well, on pros side it should be twice as fast as
* "4-bit" version. And for gcc-generated x86[_64] code, "8-bit" version
* was observed to run ~75% faster, closer to 100% for commercial
* compilers... Yet "4-bit" procedure is preferred, because it's
* believed to provide better security-performance balance and adequate
* all-round performance. "All-round" refers to things like:
*
* - shorter setup time effectively improves overall timing for
* handling short messages;
* - larger table allocation can become unbearable because of VM
* subsystem penalties (for example on Windows large enough free
* results in VM working set trimming, meaning that consequent
* malloc would immediately incur working set expansion);
* - larger table has larger cache footprint, which can affect
* performance of other code paths (not necessarily even from same
* thread in Hyper-Threading world);
*
* Value of 1 is not appropriate for performance reasons.
