ENGINE surgery. DH, DSA, RAND, and RSA now use *both* "method" and ENGINE
pointers to manage their hooking with ENGINE. Previously their use of
"method" pointers was replaced by use of ENGINE references. See
crypto/engine/README for details.
Also, remove the ENGINE iterations from evp_test - even when the
cipher/digest code is committed in, this functionality would require a
different set of API calls.
See the commit log message for that for more information.
NB: X509_STORE_CTX's use of "ex_data" support was actually misimplemented
(initialisation by "memset" won't/can't/doesn't work). This fixes that but
requires that X509_STORE_CTX_init() be able to handle errors - so its
prototype has been changed to return 'int' rather than 'void'. All uses of
that function throughout the source code have been tracked down and
adjusted.
dependant code has to directly increment the "references" value of each
such structure using the corresponding lock. Apart from code duplication,
this provided no "REF_CHECK/REF_PRINT" checking and violated
encapsulation.
setting stack (actually, array) values in ex_data. So only increment the
global counters if the underlying CRYPTO_get_ex_new_index() call succeeds.
This change doesn't make "ex_data" right (see the comment at the head of
ex_data.c to know why), but at least makes the source code marginally less
frustrating.
Split private key PEM and normal PEM handling. Private key
handling needs to link in stuff like PKCS#8.
Relocate the ASN1 *_dup() functions, to the relevant ASN1
modules using new macro IMPLEMENT_ASN1_DUP_FUNCTION. Previously
these were all in crypto/x509/x_all.c along with every ASN1
BIO/fp function which linked in *every* ASN1 function if
a single dup was used.
Move the authority key id ASN1 structure to a separate file.
This is used in the X509 routines and its previous location
linked in all the v3 extension code.
Also move ASN1_tag2bit to avoid linking in a_bytes.c which
is now largely obsolete.
So far under Linux stripped binary with single PEM_read_X509
is now 238K compared to 380K before these changes.
does not contain more bytes than the RSA modulus 'n' - it does not check
that the input is strictly *less* than 'n'. Whether this should be the
case or not is open to debate - however, due to security problems with
returning miscalculated CRT results, the 'rsa_mod_exp' implementation in
rsa_eay.c now performs a public-key exponentiation to verify the CRT result
and in the event of an error will instead recalculate and return a non-CRT
(more expensive) mod_exp calculation. As the mod_exp of 'I' is equivalent
to the mod_exp of 'I mod n', and the verify result is automatically between
0 and n-1 inclusive, the verify only matches the input if 'I' was less than
'n', otherwise even a correct CRT calculation is only congruent to 'I' (ie.
they differ by a multiple of 'n'). Rather than rejecting correct
calculations and doing redundant and slower ones instead, this changes the
equality check in the verification code to a congruence check.
applications to use EVP. Add missing calls to HMAC_cleanup() and
don't assume HMAC_CTX can be copied using memcpy().
Note: this is almost identical to the patch submitted to openssl-dev
by Verdon Walker <VWalker@novell.com> except some redundant
EVP_add_digest_()/EVP_cleanup() calls were removed and some changes
made to avoid compiler warnings.
and make all files the depend on it include it without prefixing it
with openssl/.
This means that all Makefiles will have $(TOP) as one of the include
directories.
sure they are available in opensslconf.h, by giving them names starting
with "OPENSSL_" to avoid conflicts with other packages and by making
sure e_os2.h will cover all platform-specific cases together with
opensslconf.h.
I've checked fairly well that nothing breaks with this (apart from
external software that will adapt if they have used something like
NO_KRB5), but I can't guarantee it completely, so a review of this
change would be a good thing.
the RSA_METHOD's "init()" handler is called, and is cleaned up after the
RSA_METHOD's "finish()" handler is called. Custom RSA_METHODs may wish to
initialise contexts and other specifics in the RSA structure upon creation
and that was previously not possible - "ex_data" is where that stuff
should go and it was being initialised too late for it to be used.
test was never triggered due to an off-by-one error.
In s23_clnt.c, don't use special rollback-attack detection padding
(RSA_SSLV23_PADDING) if SSL 2.0 is the only protocol enabled in the
client; similarly, in s23_srvr.c, don't do the rollback check if
SSL 2.0 is the only protocol enabled in the server.
could be done automagically, much like the numbering in libeay.num and
ssleay.num. The solution works as follows:
- New object identifiers are inserted in objects.txt, following the
syntax given in objects.README.
- objects.pl is used to process obj_mac.num and create a new
obj_mac.h.
- obj_dat.pl is used to create a new obj_dat.h, using the data in
obj_mac.h.
This is currently kind of a hack, and the perl code in objects.pl
isn't very elegant, but it works as I intended. The simplest way to
check that it worked correctly is to look in obj_dat.h and check the
array nid_objs and make sure the objects haven't moved around (this is
important!). Additions are OK, as well as consistent name changes.
Also, "make update" has added some missing functions to libeay.num,
updated the TABLE for the alpha changes, and updated thousands of
dependancies that have changed from recent commits.
was a really bad idea. For example, the following:
#include <x509.h>
#include <bio.h>
#include <asn1.h>
would make sure that things like ASN1_UTCTIME_print() wasn't defined
unless you moved the inclusion of bio.h to above the inclusion of
x509.h. The reason is that x509.h includes asn1.h, and the
declaration of ASN1_UTCTIME_print() depended on the definition of
HEADER_BIO_H. That's what I call an obscure bug.
Instead, this change makes sure that whatever header files are needed
for the correct process of one header file are included automagically,
and that the definitions of, for example, BIO-related things are
dependent on the absence of the NO_{foo} macros. This is also
consistent with the way parts of OpenSSL can be excluded at will.
like Malloc, Realloc and especially Free conflict with already existing names
on some operating systems or other packages. That is reason enough to change
the names of the OpenSSL memory allocation macros to something that has a
better chance of being unique, like prepending them with OPENSSL_.
This change includes all the name changes needed throughout all C files.
"Jan Mikkelsen" <janm@transactionsite.com> correctly states that the
OpenSSL header files have #include's and extern "C"'s in an incorrect
order. Thusly fixed.
initialised, at which point an appropriate default was chosen. This meant a
call to RSA_get_default_method might have returned FALSE.
This change fixes that; now any called to RSA_new(), RSA_new_method(NULL), or
RSA_get_default_method() will ensure that a default is chosen if it wasn't
already.
library, the output buffer always is large enough, but if the tlen
parameter is there, it should be checked in the interest of clarity,
as proposed by David Sacerdote <das33@cornell.edu>.
returns int (1 = ok, 0 = not seeded). New function RAND_add() is the
same as RAND_seed() but takes an estimate of the entropy as an additional
argument.
OpenSSL is compiled with NO_RSA, no RSA operations can be used: including
key generation storage and display of RSA keys. Since these operations are
not covered by the RSA patent (my understanding is it only covers encrypt,
decrypt, sign and verify) they can be included: this is an often requested
feature, attempts to use the patented operations return an error code.
This is enabled by setting RSA_NULL. This means that if a particular application
has its own legal US RSA implementation then it can use that instead by setting
it as the default RSA method.
Still experimental and needs some fiddling of the other libraries so they have
some options that don't attempt to use RSA if it isn't allowed.
in cryptlib.h (which is often included as "../cryptlib.h"), then the
question remains relative to which directory this is to be interpreted.
gcc went one further directory up, as intended; but makedepend thinks
differently, and so probably do some C compilers. So the ../ must go away;
thus e_os.h goes back into include/openssl (but I now use
#include "openssl/e_os.h" instead of <openssl/e_os.h> to make the point) --
and we have another huge bunch of dependency changes. Argh.
There were problems with putting e_os.h just into the top directory,
because the test programs are compiled within test/ in the "standard"
case in in their original directories in the makefile.one case;
and in the latter symlinks may not be available.
to error code script: it can now find untranslatable function codes (usually
because the function is static and not defined in a header: occasionally because
of a typo...) and unreferenced function and reason codes. To see this try:
perl util/mkerr.pl -recurse -debug
Also fixed some typos in crypto/pkcs12 that this found :-)
Also tidy up some error calls that had to be all on one line: the old error
script couldn't find codes unless the call was all on one line.
script, translates function codes better and doesn't need the K&R function
prototypes to work (NB. the K&R prototypes can't be wiped just yet: they are
still needed by the DEF generator...). I also ran the script with the -rewrite
option to update all the header and source files.
consistent in the source tree and replaced `/bin/rm' by `rm'. Additonally
cleaned up the `make links' target: Remove unnecessary semicolons, subsequent
redundant removes, inline point.sh into mklink.sh to speed processing and no
longer clutter the display with confusing stuff. Instead only the actually
done links are displayed.
without -debug option to mk1mf.pl. Change _export to is_export (_export is
a reserved word under VC++). Add yucky function prototype function pointer
casts. Sanitise the included files in crypto/x509v3.
Also changed ssleay.exe target to openssl.exe
1. merge various obsolete readme texts into doc/ssleay.txt
where we collect the old documents and readme texts.
2. remove the first part of files where I'm already sure that we no longer need
them because of three reasons: either they are just temporary files which
were left by Eric or they are preserved original files where I've verified
that the diff is also available in the CVS via "cvs diff -rSSLeay_0_8_1b"
or they were renamed (as it was definitely the case for the crypto/md/
stuff).
We've still a horrible mess under crypto/bn/asm/. There for a lot of files
I'm sure whether we need them or not. So, when someone knows it better, feel
free to cleanup there.
1. The already released version was 0.9.1c and not 0.9.1b
2. The next release should be 0.9.2 and not 0.9.1d, because
first the changes are already too large, second we should avoid any more
0.9.1x confusions and third, the Apache version semantics of
VERSION.REVISION.PATCHLEVEL for the version string is reasonable (and here
.2 is already just a patchlevel and not major change).
