- *) Not all of this is true any longer.
- Will have to be updated to reflect all subsequent changes to cryptlib.c.
- --bodo
-
-
- To support arbitrarily-typed thread IDs, deprecate the existing
- type-specific APIs for a general purpose CRYPTO_THREADID
- interface. Applications can choose the thread ID
- callback type it wishes to register, as before;
-
- void CRYPTO_set_id_callback(unsigned long (*func)(void));
- void CRYPTO_set_idptr_callback(void *(*func)(void));
-
- but retrieval, copies, and comparisons of thread IDs are via
- type-independent interfaces;
-
- void CRYPTO_THREADID_set(CRYPTO_THREADID *id);
- void CRYPTO_THREADID_cmp(const CRYPTO_THREADID *id1,
- const CRYPTO_THREADID *id2);
- void CRYPTO_THREADID_cpy(CRYPTO_THREADID *dst,
- const CRYPTO_THREADID *src);
-
- Also, for code that needs a thread ID "value" for use in
- hash-tables or logging, a "hash" is available by;
-
- unsigned long CRYPTO_THREADID_hash(const CRYPTO_THREADID *id);
-
- This hash value is likely to be the thread ID anyway, but
- otherwise it will be unique if possible or as collision-free as
- possible if uniqueness can't be guaranteed on the target
- architecture.
-
- The following functions are deprecated;
- unsigned long (*CRYPTO_get_id_callback(void))(void);
- unsigned long CRYPTO_thread_id(void);
-
- As a consequence of the above, there are similar deprecations of
- BN_BLINDING functions in favour of CRYPTO_THREADID-based
- alternatives;
-
- #ifndef OPENSSL_NO_DEPRECATED
- unsigned long BN_BLINDING_get_thread_id(const BN_BLINDING *);
- void BN_BLINDING_set_thread_id(BN_BLINDING *, unsigned long);
- #endif
- void BN_BLINDING_set_thread(BN_BLINDING *);
- int BN_BLINDING_cmp_thread(const BN_BLINDING *, const
- CRYPTO_THREADID *);
-
- Also, the ERR_remove_state(int pid) API has been deprecated;
-
- #ifndef OPENSSL_NO_DEPRECATED
- void ERR_remove_state(unsigned long pid)
- #endif
- void ERR_remove_thread_state(CRYPTO_THREADID *tid);
-
- [Geoff Thorpe]
-
*) Initial support for Cryptographic Message Syntax (aka CMS) based
on RFC3850, RFC3851 and RFC3852. New cms directory and cms utility,
support for data, signedData, compressedData, digestedData and
callback is &errno.
[Bodo Moeller]
- -- NOTE -- this change has been reverted and replaced with a
- type-independent wrapper (ie. applications do not have to check
- two type-specific thread ID representations as implied in this
- change note). However, the "idptr" callback form described here
- can still be registered. Please see the more recent CHANGES note
- regarding CRYPTO_THREADID. [Geoff Thorpe]
- -- NOTE --
-
*) Change the array representation of binary polynomials: the list
of degrees of non-zero coefficients is now terminated with -1.
Previously it was terminated with 0, which was also part of the

BN_BLINDING_get_flags() returns the BN_BLINDING flags. Currently
there are two supported flags: B<BN_BLINDING_NO_UPDATE> and
BN_BLINDING_get_thread_id() returns the thread id (a B<unsigned long>
value) or 0 if not set.
-BN_BLINDING_cmp_thread() returns 0 if the thread id associated with the
-B<BN_BLINDING> structure equals the provided thread id (which can be
-obtained by CRYPTO_THREADID_set()), otherwise it returns -1 or +1
-to indicate the thread ids are different (if the target architecture
-supports ordering of thread ids, this follows the traditional "cmp"
-semantics of memcmp() or strcmp()).
BN_BLINDING_get_flags() returns the currently set B<BN_BLINDING> flags
(a B<unsigned long> value).
BN_BLINDING_set_thread_id, BN_BLINDING_set_flags, BN_BLINDING_get_flags

Additionally, OpenSSL supports dynamic locks, and sometimes, some parts
of OpenSSL need it for better performance. To enable this, the following
something other than an integer. It is for cases like this that
CRYPTO_set_idptr_callback() comes in handy. (E.g., call malloc(1)
once in each thread, and have idptr_function() return a pointer to
