His comments are:
First, it corrects a problem introduced in the last patch where the
kssl_map_enc() would intentionally return NULL for valid ENCTYPE
values. This was done to prevent verification of the kerberos 5
authenticator from being performed when Derived Key ciphers were
in use. Unfortunately, the authenticator verification routine was
not the only place that function was used. And it caused core dumps.
Second, it attempt to add to SSL_SESSION the Kerberos 5 Client
Principal Name.
DES's keyschedules.
I know these two should be separate, and I'll back out the DES changes if they
are deemed to be an error.
Note that there is a memory leak lurking in SSL somewhere in this version.
HP-UX in common in ./config). Note that for the moment of this writing
none of 64-bit platforms pass bntest. I'm committing this anyway as it's
too frustrating to patch snapshots over and over while 0.9.6 is known to
work.
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.
reduce linker bloat. For example the
single line:
PEM_read_X509()
results in a binary of around 400K in Linux!
This first step separates some of the PEM functions and
avoids linking in some PKCS#7 and PKCS#12 code.
explicitely noted that 64-bit SPARCv9 ABI is not officially supported
by GCC 3.0 (support is scheduled for 3.1 release), but it appears to
work, at the very least 'make test' passes...
possible problems.
- New file breakage.c handles (so far) missing functions.
- Get rid of some signed/unsigned/const warnings thanks to solaris-cc
- Add autoconf/automake input files, and helper scripts to populate missing
(but auto-generated) files.
This change adds a configure.in and Makefile.am to build everything using
autoconf, automake, and libtool - and adds "gunk" scripts to generate the
various files those things need (and clean then up again after). This means
that "autogunk.sh" needs to be run first on a system with the autotools,
but the resulting directory should be "configure"able and compilable on
systems without those tools.
His comments are:
This patch fixes the problem of modern Kerberos using "derived keys"
to encrypt the authenticator by disabling the authenticator check
for all derived keys enctypes.
I think I've got all the bugfixes that Jeffrey and I discussed rolled
into this. There were some problems with Jeffrey's code to convert
the authenticator's Kerberos timestring into struct tm (e.g. Z, -1900;
it helps to have an actual decryptable authenticator to play with).
So I've shamelessly pushed in my code, while stealing some bits from
Jeffrey.
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.
