660 | /* Bignum consistency macros | ||
661 | * There is one "API" macro, bn_fix_top(), for stripping leading zeroes from | ||
662 | * bignum data after direct manipulations on the data. There is also an | ||
663 | * "internal" macro, bn_check_top(), for verifying that there are no leading | ||
664 | * zeroes. Unfortunately, some auditing is required due to the fact that | ||
665 | * bn_fix_top() has become an overabused duct-tape because bignum data is | ||
666 | * occasionally passed around in an inconsistent state. So the following | ||
667 | * changes have been made to sort this out; | ||
668 | * - bn_fix_top()s implementation has been moved to bn_correct_top() | ||
669 | * - if BN_DEBUG isn't defined, bn_fix_top() maps to bn_correct_top(), and | ||
670 | * bn_check_top() is as before. | ||
671 | * - if BN_DEBUG *is* defined; | ||
672 | * - bn_check_top() tries to pollute unused words even if the bignum 'top' is | ||
673 | * consistent. (ed: only if BN_DEBUG_RAND is defined) | ||
674 | * - bn_fix_top() maps to bn_check_top() rather than "fixing" anything. | ||
675 | * The idea is to have debug builds flag up inconsistent bignums when they | ||
676 | * occur. If that occurs in a bn_fix_top(), we examine the code in question; if | ||
677 | * the use of bn_fix_top() was appropriate (ie. it follows directly after code | ||
678 | * that manipulates the bignum) it is converted to bn_correct_top(), and if it | ||
679 | * was not appropriate, we convert it permanently to bn_check_top() and track | ||
680 | * down the cause of the bug. Eventually, no internal code should be using the | ||
681 | * bn_fix_top() macro. External applications and libraries should try this with | ||
682 | * their own code too, both in terms of building against the openssl headers | ||
683 | * with BN_DEBUG defined *and* linking with a version of OpenSSL built with it | ||
684 | * defined. This not only improves external code, it provides more test | ||
685 | * coverage for openssl's own code. | ||
