Changes between 0.9.3a and 0.9.4 [xx Jul/Aug/...? 1999]
*) Added support for SPARC Linux.
[Andy Polyakov]
*) pem_password_cb function type incompatibly changed from
typedef int pem_password_cb(char *buf, int size, int rwflag);
to
....(char *buf, int size, int rwflag, void *userdata);
so that applications can pass data to their callbacks:
The PEM[_ASN1]_{read,write}... functions and macros now take an
additional void * argument, which is just handed through whenever
the password callback is called.
[Damien Miller <dmiller@ilogic.com.au>, with tiny changes by Bodo Moeller]
New function SSL_CTX_set_default_passwd_cb_userdata.
Compatibility note: As many C implementations push function arguments
onto the stack in reverse order, the new library version is likely to
interoperate with programs that have been compiled with the old
pem_password_cb definition (PEM_whatever takes some data that
happens to be on the stack as its last argument, and the callback
just ignores this garbage); but there is no guarantee whatsoever that
this will work.
*) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=...
(both in crypto/Makefile.ssl for use by crypto/cversion.c) caused
problems not only on Windows, but also on some Unix platforms.
To avoid problematic command lines, these definitions are now in an
auto-generated file, which also defines DATE and thus replaces
crypto/date.h. Standard "make" builds use crypto/buildinf.h,
mk1mf.pl builds use crypto/mk1mfinf.h (created by mk1mf.pl).
[Bodo Moeller]
*) MIPS III/IV assembler module is reimplemented.
[Andy Polyakov]
*) More DES library cleanups: remove references to srand/rand and
delete an unused file.
[Ulf Möller]
Dr. Stephen Henson
committed
*) Add support for the the free Netwide assembler (NASM) under Win32,
since not many people have MASM (ml) and it can be hard to obtain.
This is currently experimental but it seems to work OK and pass all
the tests. Check out INSTALL.W32 for info.
[Steve Henson]
*) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections
without temporary keys kept an extra copy of the server key,
and connections with temporary keys did not free everything in case
of an error.
[Bodo Moeller]
*) New function RSA_check_key and new openssl rsa option -check
for verifying the consistency of RSA keys.
[Ulf Moeller, Bodo Moeller]
*) Various changes to make Win32 compile work:
1. Casts to avoid "loss of data" warnings in p5_crpt2.c
2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned
comparison" warnings.
3. Add sk_<TYPE>_sort to DEF file generator and do make update.

[Steve Henson]
*) Add a debugging option to PKCS#5 v2 key generation function: when
you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and
derived keys are printed to stderr.
[Steve Henson]
*) Copy the flags in ASN1_STRING_dup().
[Roman E. Pavlov <pre@mo.msk.ru>]
Dr. Stephen Henson
committed
*) The x509 application mishandled signing requests containing DSA
keys when the signing key was also DSA and the parameters didn't match.
It was supposed to omit the parameters when they matched the signing key:
the verifying software was then supposed to automatically use the CA's
parameters if they were absent from the end user certificate.
Omitting parameters is no longer recommended. The test was also
the wrong way round! This was probably due to unusual behaviour in
EVP_cmp_parameters() which returns 1 if the parameters match.
This meant that parameters were omitted when they *didn't* match and
the certificate was useless. Certificates signed with 'ca' didn't have
this bug.
[Steve Henson, reported by Doug Erickson <Doug.Erickson@Part.NET>]
*) Memory leak checking (-DCRYPTO_MDEBUG) had some problems.
The interface is as follows:
Applications can use
CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(),
CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop();
"off" is now the default.
The library internally uses
CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(),
CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on()
to disable memory-checking temporarily.
Some inconsistent states that previously were possible (and were
even the default) are now avoided.
-DCRYPTO_MDEBUG_TIME is new and additionally stores the current time
with each memory chunk allocated; this is occasionally more helpful
than just having a counter.
-DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID.
-DCRYPTO_MDEBUG_ALL enables all of the above, plus any future
extensions.
*) Introduce "mode" for SSL structures (with defaults in SSL_CTX),
which largely parallels "options", but is for changing API behaviour,
whereas "options" are about protocol behaviour.
Initial "mode" flags are:
SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when
a single record has been written.
SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write
retries use the same buffer location.
(But all of the contents must be
copied!)
[Bodo Moeller]
*) Bugfix: SSL_set_mode ignored its parameter, only SSL_CTX_set_mode
worked.
*) Fix problems with no-hmac etc.
[Ulf Möller, pointed out by Brian Wellington <bwelling@tislabs.com>]
Dr. Stephen Henson
committed
*) New functions RSA_get_default_method(), RSA_set_method() and
RSA_get_method(). These allows replacement of RSA_METHODs without having
to mess around with the internals of an RSA structure.
[Steve Henson]
*) Fix memory leaks in DSA_do_sign and DSA_is_prime.
Also really enable memory leak checks in openssl.c and in some
test programs.
[Chad C. Mulligan, Bodo Moeller]
Dr. Stephen Henson
committed
*) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess
up the length of negative integers. This has now been simplified to just
store the length when it is first determined and use it later, rather
than trying to keep track of where data is copied and updating it to
point to the end.
[Steve Henson, reported by Brien Wheeler
<bwheeler@authentica-security.com>]
*) Add a new function PKCS7_signatureVerify. This allows the verification
of a PKCS#7 signature but with the signing certificate passed to the
function itself. This contrasts with PKCS7_dataVerify which assumes the
certificate is present in the PKCS#7 structure. This isn't always the
case: certificates can be omitted from a PKCS#7 structure and be
distributed by "out of band" means (such as a certificate database).
[Steve Henson]
Dr. Stephen Henson
committed
*) Complete the PEM_* macros with DECLARE_PEM versions to replace the
function prototypes in pem.h, also change util/mkdef.pl to add the
necessary function names.
[Steve Henson]
*) mk1mf.pl (used by Windows builds) did not properly read the
options set by Configure in the top level Makefile, and Configure
was not even able to write more than one option correctly.
Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended.
Dr. Stephen Henson
committed
*) New functions CONF_load_bio() and CONF_load_fp() to allow a config
file to be loaded from a BIO or FILE pointer. The BIO version will
for example allow memory BIOs to contain config info.
[Steve Henson]
*) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
Whoever hopes to achieve shared-library compatibility across versions
must use this, not the compile-time macro.
(Exercise 0.9.4: Which is the minimum library version required by
such programs?)
Note: All this applies only to multi-threaded programs, others don't
need locks.
*) Add missing case to s3_clnt.c state machine -- one of the new SSL tests
through a BIO pair triggered the default case, i.e.
SSLerr(...,SSL_R_UNKNOWN_STATE).
[Bodo Moeller]
*) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications
can use the SSL library even if none of the specific BIOs is
appropriate.
[Bodo Moeller]
*) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value
for the encoded length.
[Jeon KyoungHo <khjeon@sds.samsung.co.kr>]
Dr. Stephen Henson
committed
*) Add initial documentation of the X509V3 functions.
