handle an externally provided "static" buffer as well a a dynamic
buffer. The "static" buffer is filled first, but if overflowed, the
dynamic buffer is used instead, being allocated somewhere i the heap.
This combines the benefits of putting the output in a preallocated
buffer (on the stack, for example) and in a buffer that grows
somewhere in the heap.
add some whitespace for 'if ()', 'for ()', 'while ()' to distinguish
keywords from function names, and finally remove parens around return
values (why be stingy with whitespace but fill the source code
with an abundance of parentheses that are not needed to structure
expressions for readability?).
The old code was painfully primitive and couldn't handle
distinct certificates using the same subject name.
The new code performs several tests on a candidate issuer
certificate based on certificate extensions.
It also adds several callbacks to X509_VERIFY_CTX so its
behaviour can be customised.
Unfortunately some hackery was needed to persuade X509_STORE
to tolerate this. This should go away when X509_STORE is
replaced, sometime...
This must have broken something though :-(
If some other thread deletes the BIO that one thread needs for
BIO_write, then there's a lot of trouble anyway; there's
nothing special about calling the callback.
Returning -1 for an attempt to read from an empty buffer is empty is
not an error that should be signalled via the error queue, it's a
'retry read' condition and is signalled as such.
This allows intermediate CAs to be created more easily.
PKCS12_create() now checks private key matches certificate.
Fix typo in x509 app.
Update docs.
New function ASN1_STRING_to_UTF8() converts any ASN1_STRING
type to UTF8.
initialize ex_pathlen to -1 so it isn't checked if pathlen
is not present.
set ucert to NULL in apps/pkcs12.c otherwise it gets freed
twice.
remove extraneous '\r' in MIME encoder.
Allow a NULL to be passed to X509_gmtime_adj()
Make PKCS#7 code use definite length encoding rather then
the indefinite stuff it used previously.
records, EVP_EncodeUpdate() may misbehave. This happens when there's
a record boundary between the two ending b64 equal signs, which makes
EVP_EncodeUpdate think there has been more than one EOF, and therefore
add an extra NUL at the end of the output buffer. This fix corrects
that problem.
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.
functions. These are intended to be replacements
for the ancient ASN1_STRING_print() and X509_NAME_print()
functions.
The new functions support RFC2253 and various pretty
printing options. It is also possible to display
international characters if the terminal properly handles
UTF8 encoding (Linux seems to tolerate this if the
"unicode_start" script is run).
Still needs to be documented, integrated into other
utilities and extensively tested.
size) through the base64 filter, b64_write() messes up it's parameters
in such a way that instead of writing correct base64 output, the first
4 characters of that output is repeated over and over. This fix
corrects that problem.
it wants to stir the pool using ssleay_rand_add. This fix provides the
possibility to call ssleay_rand_add inside a locked state by simply telling
it not to do any locking through a static variable. This isn't the most
elegant way one could do this, but it does retain thread safety during the
stirring process.
there's support for building under Linux and True64 (using examples
from the programming manuals), including versioning that is currently
the same as OpenSSL versions but should really be a different series.
With this change, it's up to the users to decide if they want shared
libraries as well as the static ones. This decision now has to be
done at configuration time (well, not really, those who know what they
do can still do it the same way as before).
The OpenSSL programs (openssl and the test programs) are currently
always linked statically, but this may change in the future in a
configurable manner. The necessary makefile variables to enable this
are in place.
Also note that I have done absolutely nothing about the Windows target
to get something similar. On the other hand, DLLs are already the
default there, but without versioning, and I've no idea what the
possibilities for such a thing are there...
call the i2c/c2i (they were not using the
content length for the headers).
Fix ASN1 long form tag encoding. This never
worked but it was never tested since it is
only used for tags > 30.
New options to smime program to allow the
PKCS#7 format to be specified and the content
supplied externally.
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.
the 'INSTALL' file, which means that 9 times of 10, the BlowFish
headers won't get installed. Avoid this in the same way it's done in
crypto/des/Makefile.ssl, where someone apparently has thought of this...
into lexical order. Previously it depended on
the order of files in the directory.
This should now mean that all systems will
agree on the order of safestack.h and will
not change it needlessly and avoid massive
needless commits to safestack.h in future.
It wont however avoid this one :-(
it cope with OpenBSD which doesn't understand "RTLD_NOW".
* Added the dso_scheme config string entry for OpenBSD-x86 to give it
DSO support.
* 'make update' that has also absorbed some of Steve's mkstack changes
for the ASN-related macros.
This is mostly a work around for the old VC++ problem
that it treats func() as func(void).
Various prototypes had been added to 'compare' function
pointers that triggered this. This could be fixed by removing
the prototype, adding function pointer casts to every call or
changing the passed function to use the expected arguments.
I mostly did the latter.
The mkdef.pl script was modified to remove the typesafe
functions which no longer exist.
Oh and some functions called OPENSSL_freeLibrary() were
changed back to FreeLibrary(), wonder how that happened :-)
Also, make sure empty slots of the dynamic lock stack are used.
Actually, I'm not really sure this is the right thing to do, and may
remove it, with an endlessly growing stack as result...
insecure, so a static lock is added to isolate the sensitive parts.
Also, to avoid one thread freeing a lock that is used by another, a
reference counter is added.
be needed in some ENGINE code, and might serve elsewhere as well.
Note that it's implemented in such a way that the locking itself is
done through the same CRYPTO_lock function as the static locks.
WARNING: This is currently experimental and untested code (it will get
tested soon, though :-)).
sk_whatever_insert and sk_whatever_set immediately reveals the subtle
difference in parameter order.
Change mkstack.pl so that safestack.h is not rewritten when
nothing has changed.
After some messing around this seems to work but needs
a few more tests. Working out the syntax for sk_set_cmp_func()
(cast it to a function that itself returns a function pointer)
was painful :-(
Needs some testing to see what other compilers think of this
syntax.
Also needs similar stuff for ASN1_SET_OF etc etc.
