deprecate the original (numeric-only) scheme, and replace with the
CRYPTO_THREADID object. This hides the platform-specifics and should reduce
the possibility for programming errors (where failing to explicitly check
both thread ID forms could create subtle, platform-specific bugs).
Thanks to Bodo, for invaluable review and feedback.
to 'unsigned long' (ie. odd platforms/compilers), so a pointer-typed
version was added but it required portable code to check *both* modes to
determine equality. This commit maintains the availability of both thread
ID types, but deprecates the type-specific accessor APIs that invoke the
callbacks - instead a single type-independent API is used. This simplifies
software that calls into this interface, and should also make it less
error-prone - as forgetting to call and compare *both* thread ID accessors
could have led to hard-to-debug/infrequent bugs (that might only affect
certain platforms or thread implementations). As the CHANGES note says,
there were corresponding deprecations and replacements in the
thread-related functions for BN_BLINDING and ERR too.
CRYPTO_get_idptr_callback(), CRYPTO_thread_idptr() for a 'void *' type
thread ID, since the 'unsigned long' type of the existing thread ID
does not always work well.
if we explicitly intruct the linker to set entry point, then we become
obliged to initialize run-time library. Instead we can pick name run-time
will call and such name is DllMain. Note that this applies to both
"native" Win32 environment and Cygwin:-)
is to have a placeholder to small routines, which can be written only
in assembler. In IA-32 case this includes processor capability
identification and access to Time-Stamp Counter. As discussed earlier
OPENSSL_ia32cap is introduced to control recently added SSE2 code
pathes (see docs/crypto/OPENSSL_ia32cap.pod). For the moment the
code is operational on ELF platforms only. I haven't checked it yet,
but I have all reasons to believe that Windows build should fail to
link too. I'll be looking into it shortly...
pushed item. The index is the number of items - 1. And if a NULL item was
found, actually use it.
Finally, provide a little bit of safety in CRYPTO_lock() by asserting the a
requested dynamic lock really must exist, instead of just being silent about it
Additional changes:
- use EC_GROUP_get_degree() in apps/req.c
- add ECDSA and ECDH to apps/speed.c
- adds support for EC curves over binary fields to ECDSA
- new function EC_KEY_up_ref() in crypto/ec/ec_key.c
- reorganize crypto/ecdsa/ecdsatest.c
- add engine support for ECDH
- fix a few bugs in ECDSA engine support
