From simon at josefsson.org Wed May 2 15:50:41 2007 From: simon at josefsson.org (Simon Josefsson) Date: Wed, 02 May 2007 15:50:41 +0200 Subject: [gnutls-dev] GnuTLS 1.7.8.p11.0 Message-ID: <877irruyfi.fsf@mocca.josefsson.org> Here is the first release on the PKCS#11 branch. The support is currently rather limited, but I decided to make a release early to invite more feedback. The NEWS entry is: * Version 1.7.8.p11.0 (released 2007-05-02) ** New function to get trusted CA certificates from PKCS#11 provider. ** API and ABI modifications: gnutls_pkcs11_get_ca_certificates: ADD. Warning! This is even more experimental than the experimental 1.7.x branch. However, the changes compared to 1.7.8 are intentionally kept minimal, to facilitate easy merging later on. The support is limited to: 1) Support for build-time linking to the PKCS#11 provider scute, see http://www.scute.org/. 2) Retrieving trusted CA certificates from the PKCS#11 provider. To test it, you'll need to build scute from SVN (because it contains a CKA_TRUSTED related fix), and set it up (try using it in mozilla), which can be non-trivial. See the Scute manual. I generated new keys on an OpenPGP smartcard with gpg2 --edit-card and gpgsm-gencert.sh, then signed the CSR with certtool using the GnuTLS test CA, and imported the certificates using 'gpgsm --import'. If someone can explain to me how I can test other PKCS#11 providers, I can test them too. Supporting the NSS soft token provider is an important target. The gnutls-cli tool in this release automatically import all CAs from Scute, and here is an output from running it against the GnuTLS test server: jas at mocca:~$ ~/src/gnutls-pkcs11/src/gnutls-cli --port 5556 test.gnutls.org --ctypes x509 Resolving 'test.gnutls.org'...

Notice that it says the peer's certificate is trusted, without any --x509certfile. The GnuTLS CA is retrieved from Scute.

Actually, I've been using Arch for several years, but I've been pondering the idea of switching to GIT (or "Git", whatever) recently. So if you're willing to switch, I'd be happy with that, probably happier than with CVS anyway. ;-) Otherwise, if you don't want to switch right now, I can cope with CVS. Thanks, Ludovic.

I'll see if I can set up a Git<->CVS gateway using repo.or.cz quickly, and then we can use it as a test whether migrating to Git will work or not. What do you think?

So I ask you again, please implement a callback structure for engines, this callback should have the following methods: typedef struct { void *user_data; int (*init)(void *user_data); int (*cleanup)(void *user_data); int (*sign)(void *user_data, int algorithm, size_t input_size, const unsigned char * const input, size_t *output_size, unsigned char * const output); int (*decrypt)(void *user_data, int algorithm, size_t input_size, const unsigned char * const input, size_t *output_size, unsigned char * const output); } engine_t; Provide a replacement function for: gnutls_certificate_set_x509_key_file () Something like: gnutls_certificate_set_x509_key_engine (gnutls_certificate_credentials_t res, engine_t *engine) This will allow application to enumerate the token certificates, set the trust correctly by using the regular gnutls_certificate_set_x509_trust_file() call, and handle the sign/decrypt in any way it likes... One implementation may be PKCS#11. As I said before, if you provide such interface, I will provide a *COMPLETE* and *WORKING* PKCS#11 support for GnuTLS, after a day or two. It will also clean up your implementation, and allow many other engines to be added. Another alternative is to wait for you to have a remotely working solution, and create a patch for the above (this is what I intended to do now...), but it would be much cleaner if you create the interface as you know GnuTLS best, and it will save a lot of work for all. Please consider to cooperate, you loose nothing, as you will be able to use the same interface for your implementation as-well. Best Regards, Alon Bar-Lev.

It may start out as somewhat simpler, to better fit with how the GnuTLS API works today: right now applications can be invoked with a callback to retrieve the appropriate cert+key. They need some function to get the user certificates and key handles from the PKCS#11 layer. I'm thinking this interface will be: int gnutls_pkcs11_get_user_certificates (gnutls_x509_crt_t ** cert_list, unsigned int *ncerts); Or similar. When an application, in the certificate callback, indicate that the private key is 'NULL', they will have to provider another callback to perform the sign operation, otherwise the user certificate will be ignored. That function should likely receive the user certificate or similar. GnuTLS should have an API available to perform the sign operation using PKCS#11, but it could also let the application perform the sign operation in any way it chose. This way, the interface will not be specific to PKCS#11, but it will be easy to make PKCS#11 work. > This will allow application to enumerate the token certificates, set > the trust correctly by using the regular > gnutls_certificate_set_x509_trust_file() call, and handle the > sign/decrypt in any way it likes... One implementation may be PKCS#11. I started providing such an API, but then I realized that it doesn't work with the callback approach that GnuTLS offers. gnutls_certificate_set_key etc doesn't do anything if used within a callback. Hence the current more flexible approach, which doesn't involve modifying the gnutls_certificate_* functions or structures. > As I said before, if you provide such interface, I will provide a > *COMPLETE* and *WORKING* PKCS#11 support for GnuTLS, after a day or > two. > > It will also clean up your implementation, and allow many other > engines to be added. > > Another alternative is to wait for you to have a remotely working > solution, and create a patch for the above (this is what I intended to > do now...), but it would be much cleaner if you create the interface > as you know GnuTLS best, and it will save a lot of work for all. > > Please consider to cooperate, you loose nothing, as you will be able > to use the same interface for your implementation as-well. Of course! I think the best is for me to produce an API that works for me and fits with how GnuTLS works. I believe it will be quite close to what you need, even if not perfectly the same. The API will not be fixed until it is merged into the normal experimental branch. There will be several iterations of release on the PKCS#11 branch until that happens, and your input is valuable here. I think it would be useful to demonstrate interoperability with at least some other PKCS#11 provider than Scute until the API is ready.

Most tokens do not hold certificate chain within them, it is just a waste of memory when you have 16K, 32K or 64K. Also I already warned you that this is highly insecure... Since anyone can store whatever certificates as public objects, thus modifying the trust. > It will be something like that.

As I see it you can have the PKCS#11 stuff maintained separately, as an optional components, something like gnutls-pkcs11 that will use the engine API in order to add the above function. You also don't handle much of the issues related of token management... 1. Tokens are ****SLOW***** enumerating the certificates takes ****LONG**** time. 2. Tokens are dynamic, you can remove them and insert them, so enumerating all available tokens every time is not wise. 3. You may have more than one token available at the same time, you may need to handle this state. 4. As I understand from your API documentation, gnutls_x509_crt_t has nothing to do with the private key, which is the one that really important when you handle hardware tokens. > When an application, in the certificate callback, indicate that the > private key is 'NULL', they will have to provider another callback to > perform the sign operation, otherwise the user certificate will be > ignored.

How do you set user defined data for the callback to be used? I did not see this in the GnuTLS documentation. Anyway... I think that your implementation should not be differnet than any other one.

But I suggest that the low-level PKCS#11 will reuse current effort and knowledge. Also I think it would be best if the PKCS#11 support will be provided as a separate library, that uses GnuTLS API. The functions: gnutls_pkcs11_set_config() /* Set providers and parameters */ gnutls_pkcs11_enum_certificates() /* Enumerate available certificates */ gnutls_pkcs11_serialize_certificate() /* Serialize specific certificate so we don't need enum again */ gnutls_pkcs11_deserialize_certificate() /* Deserialize certificate, good for configuration files */ Can be implemented using PKCS#11 code and GnuTLS with engine API as a separate library. Also, if you would like to be more generic you should provide an engines much more powerful and allow gnutls to serialize/deserialize any certificate includeing the engine specific information, and allow callbacks for an engine to enumerate certificates.

The reason why all the tests are failing is that the mapping of 'FILE *tmpfile (void)' fails. IMHO wine supports the tmpfile() mapping because opencdk uses this functions since the begin and older gnutls(win32) builds are working.

It seems there are other minor problems with the code and WINE. For example I get an EOF where I shouldn't get one. Maybe we can disable the opencdk tests for the mingw32 build until we found a solution? Maybe this is not just a WINE problem, but also a real win32 problem. I currently have no w32 box for tests. But it would be useful to know if the test files (t-encr.exe) would fail on a real w32 system.

I did copy all files from the 0.6.0 release into libextra/opencdk and it appeared to build, but I'm not sure it works. /Simon From simon at josefsson.org Fri May 4 16:08:29 2007 From: simon at josefsson.org (Simon Josefsson) Date: Fri, 04 May 2007 16:08:29 +0200 Subject: [gnutls-dev] OpenCDK 0.6.0 problems In-Reply-To: <463B2BBD.2010108@gmx.net> (Timo Schulz's message of "Fri\, 04 May 2007 14\:49\:01 +0200") References: <46377548.7060109@gmx.net> <878xc5hkc0.fsf@mocca.josefsson.org> <871whxhk1m.fsf_-_@mocca.josefsson.org> <463B2BBD.2010108@gmx.net> Message-ID: <871whw65r6.fsf@mocca.josefsson.org> Timo Schulz writes: > Simon Josefsson wrote: > >> /bin/sh ../libtool --tag=CC --mode=link i586-mingw32msvc-gcc -g -O2 -Wall -Wcast-align -Wshadow -Wstrict-prototypes -no-undefined -export-symbols ../../../src/opencdk-0.6.0/src/opencdk.def -version-info 10:0:0 -o libopencdk.la -rpath /home/jas/gnutls4win/inst/lib new-packet.lo read-packet.lo proc-packet.lo write-packet.lo main.lo verify.lo armor.lo sig-check.lo sign.lo keydb.lo keylist.lo seskey.lo pubkey.lo misc.lo encrypt.lo trustdb.lo kbnode.lo compress.lo literal.lo cipher.lo stream.lo stream-socket.lo keyserver.lo keygen.lo -L/home/jas/gnutls4win/inst/lib -lgcrypt -L/home/jas/gnutls4win/inst/lib -lgpg-error -lws2_32 >> libtool: link: symbol file `../../../src/opencdk-0.6.0/src/opencdk.def' does not exist >> make[2]: *** [libopencdk.la] Error 1 >> make[2]: Leaving directory `/home/jas/gnutls4win/build/opencdk-0.6.0/src' > > Oh, I assumed that the integrated version would be build as a static > lib.

For now I changed the makefile so it will only execute tests which are supposed to work for mingw32. For Posix systems, all tests will be executed of course. This will at least fix the problems temporary, until I found a better solution. Timo p.s. If this fixes the build errors, I will prepare a new release.

It seems to me that anyone who can make the PKCS#11 provider give GnuTLS an insecure CA cert can also provide GnuTLS directly with a insecure CA cert.

Sure -- the PKCS#11 support that GnuTLS will provide will always be optional. Applications that doesn't like the GnuTLS PKCS#11 implementation can implement their own callback function to retrieve user/CA certs and handle signing requests. > You also don't handle much of the issues related of token management... > 1.

I don't know how to solve this yet. If you want to work on it, that could help, although right now I just want to get client-PKI via the OpenPGP smart card to work, and that's my main priority. >> When an application, in the certificate callback, indicate that the >> private key is 'NULL', they will have to provider another callback to >> perform the sign operation, otherwise the user certificate will be >> ignored.

See gnutls_certificate_client_set_retrieve_function(), and for example the 'cert_callback' function in src/cli.c (the gnutls-cli tool). That callback is invoked during the TLS handshake to get the user certificate and private key to use. My idea is to allow the function to return a private key 'NULL' which indicate that GnuTLS will have to callback into the application to perform the private key operation. These APIs will not be PKCS#11 specific. > Anyway...

Yup, the idea is to have a generic mechanism, and to provide the necessary PKCS#11 glue to make it easy to use the generic mechanism with PKCS#11 providers. Application doesn't need to use the glue code though. >> Of course! I think the best is for me to produce an API that works for >> me and fits with how GnuTLS works.

I want to keep the PKCS#11 APIs minimal. It should provide basic functionality for applications that want to build on it. Applications that wants to get fancy can do their own PKCS#11 integration. /Simon From alon.barlev at gmail.com Fri May 4 17:21:46 2007 From: alon.barlev at gmail.com (Alon Bar-Lev) Date: Fri, 4 May 2007 18:21:46 +0300 Subject: [gnutls-dev] GnuTLS 1.7.8.p11.0 In-Reply-To: <87wszo4qks.fsf@mocca.josefsson.org> References: <877irruyfi.fsf@mocca.josefsson.org> <9e0cf0bf0705031345t380e9940sfa61e853fea4b262@mail.gmail.com> <87r6pw7pzm.fsf@mocca.josefsson.org> <9e0cf0bf0705040531h4cb99e4dl3e469afa5d3b98dd@mail.gmail.com> <87wszo4qks.fsf@mocca.josefsson.org> Message-ID: <9e0cf0bf0705040821u6bae0c6aodfc6d12451e0b129@mail.gmail.com> On 5/4/07, Simon Josefsson wrote: > I don't understand this.

I see we are not communicating well... So I say this last time and I say this clearly. I offer you the quickest way to achieve your goal. Split the work into two parts, one part is the GnuTLS infrastructure missing external private key implementation, the other is PKCS#11 engine. You implement the GnuTLS stuff, I implement the PKCS#11 engine, this way everyone is doing what he is best of. Now, you will have "A" working PKCS#11 implementation. Why "A", since you may decide you can do this better, and implement "THE" PKCS#11 engine on your own later, it will take you a while to mess with PKCS#11, learn how people are using it, where and when, address different provider implementations and incompatibilities etc... But you will have "A" working provider so you can learn and copy whatever you like, it will be GPLed, so no licensing problem here. This means that you STOP writing PKCS#11 low level code, and consentrate on the missing functionality of GnuTLS, document the engine interface and then test out if my implementation meets your needs.

Oh, I see. Are there smart cards out there that doesn't require an admin-PIN in order to do that? Maybe it would be good to document this somewhere, it seems like a good thing to know before buying such products. If this is the case, I'll add documentation for gnutls_pkcs11_get_ca_certificates: * Note that there exists PKCS#11 providers that allow users to add * trusted CA certificates to the underlying crypto storage. Thus, an * attacker could, if they can access your smart card, install a new * trusted CA on your smart card, and then cause this function to * return their CA.

Well, as I've tried to explain, that is what I'm working on. What may be confusing is that I'm _also_ working on an optional libgnutls-pkcs11 that links to Scute. That is written for testing purpose, since the only smart card I have is an OpenPGP smart card, and I've decided that my goal for this project is to make OpenPGP cards work with client-authenticated connections (and I chose PKCS#11 to do that). Hopefully the signing infrastructure will be released within a few weeks, and then you can try it... /Simon From andrew.w.nosenko at gmail.com Mon May 7 12:11:10 2007 From: andrew.w.nosenko at gmail.com (Andrew W.

Nosenko From simon at josefsson.org Tue May 8 12:24:28 2007 From: simon at josefsson.org (Simon Josefsson) Date: Tue, 08 May 2007 12:24:28 +0200 Subject: [gnutls-dev] Gnutls 1.7.8.p11.1 Message-ID: <87r6prk3z7.fsf@mocca.josefsson.org> Here is the second release on the PKCS#11 branch. This release is the first to actually support external signing operations. The included PKCS#11 wrapper can be used to as the callback to offload signing to a smartcard, see how gnutls-cli (src/cli.c) for examples on how to do this. Note that the code needs to be cleaned up, and likely contains bugs. I wanted to get this release out as fast as possible to reach testers. The NEWS entry is: * Version 1.7.8.p11.1 (released 2007-05-08) ** Add new API to perform private key operations. Use the new API gnutls_set_sign_function to set a callback function that is responsible for performing the signing operation. The callback must follow the gnutls_sign_func prototype: typedef int (*gnutls_sign_func) (gnutls_session_t session, gnutls_datum_t * cert, const gnutls_datum_t * hash_concat, gnutls_datum_t * signature); ** Add new APIs to get all user certificates from PKCS#11 provider. The gnutls_pkcs11_get_user_certificates looks for private keys, and returns certificates that have the same CKA_ID attribute. ** Add new API to perform signing via the PKCS#11 library. The function can be used by a gnutls_sign_func callback to off-load signing the operation to a PKCS#11 provider. Currently the limitation is that it doesn't support multiple private keys on the smart card (it doesn't check whether the certificate used for signing corresponds to the private key used). ** Improved PKCS#11 support in gnutls-cli tool. It will automatically try to load CA certificates (implemented in the last release) and user certificates (new in this release), and off-loads the signing operations to the PKCS#11 backend. ** API and ABI modifications: gnutls_pkcs11_get_user_certificates: ADD. gnutls_pkcs11_sign: ADD. gnutls_sign_func: ADD. gnutls_set_sign_function: ADD. gnutls_get_sign_function: ADD. Warning! This is even more experimental than the experimental 1.7.x branch. However, the changes compared to 1.7.8 are intentionally kept minimal, to facilitate easy merging later on. The support is limited to: 1) Support for build-time linking to the PKCS#11 provider scute, see http://www.scute.org/. 2) Retrieving trusted CA certificates from the PKCS#11 provider. 3) Retrieving user certificates from the PKCS#11 provider. 4) Provide a callback to perform signing operations. 5) Provide an API to perform PKCS#11 signing via the PKCS#11 provider. To test it, you'll need to build scute 1.1.0, and set it up (try using it in mozilla), which requires some reading, see the Scute manual. I generated new keys on an OpenPGP smartcard with gpg2 --edit-card and gpgsm-gencert.sh, then signed the CSR with certtool using the GnuTLS test CA, and imported the certificates using 'gpgsm --import'. If someone can explain to me how I can test other PKCS#11 providers, I can test them too. Supporting the NSS soft token provider is an important target. The gnutls-cli tool in this release automatically import all CAs from Scute, and will load the user certificates too, and invoke Scute for signing. Here is an output from running it against the GnuTLS test server: jas at mocca:~/src/gnutls-pkcs11$ ~/src/gnutls-pkcs11/src/gnutls-cli --port 5556 test.gnutls.org --ctypes x509 Resolving 'test.gnutls.org'...

Hi again.  I just realized that the work I'm doing on the PKCS#11 branch
is rather similar to what you provided a patch for here.  The code is
different from yours, but let me what you think and if you can test it:

http://article.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2006

I intend to move the external-signing callback API back into the 1.7.x
branch as soon as possible, because it looks rather safe.  I'm not sure
about our PKCS#11 interface library.  Alon Bar-Lev's comments indicate
that it may be better if we stay out of providing tighter PKCS#11
integration and leave that to him and others to work on.  I'd be happy
with that, since I personally think the PKCS#11 interface is too complex
to inspire good confidence in implementations of it.  Still, making it
easy to use OpenPGP cards is an important use-case for me.

Hello Simon,

Can you please clean up the branch removing the scote requirement and
PKCS#11 implementation, leaving only the engine callbacks so I can
work on this?

BTW: Your API need to allow adding user data pointer so that callbacks
will be able to access some private data.

Ludovic already suggested this at:
http://lists.gnupg.org/pipermail/gnutls-dev/2007-April/001434.html
And I already suggested it at:
http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001557.html

BTW2: You should add cleanup callback, so that resources can be
released on session end.
http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001557.html

We can discuss the API before you start implementation, so if you
provide the prototypes before implementation it will allow reduce
efforts.

Best Regards,
Alon Bar-Lev.

Interesting. I guess it compiles the parts of NSS and NSPR that it uses
into the the PKCS#11 module itself?

Is there documentation anywhere for this CKFW framework?

Just to clarify, the reason I'm developing the cryptoki-capi, is that
several clients of mine dislike the Mozilla state of affairs as far as
not using the OS's (in this case Windows') certificate and key store. It
makes things so much more insecure to have keys and policy littered
throughout the configuration files of each program.

We would like to add a layer for application to use...
So except get certificate/credentials/whatever, the layer should be
able to free its resources.
So if we put this at gnutls_certificate_credentials_t we should have
gnutls_certificate_free_credentials() call callback cleanup so that
resources may be released.

So that user code will look like:
gnutls_pkcs11_set_certificate (gnutls_certificate_credentials_t *cred, )

And that's it!

provider code will register sign callback, put certificate and
register clean callback.

Subject: [gnutls-dev] [PATCH] Fixing OpenPGP keyring import (again)
Message-ID: <87lkft6l94.fsf@chbouib.org>

Hi,

The patch below (against) `HEAD' fixes OpenPGP keyring import.  It
should also work for ASCII-armored keyrings, although I did not test it
since I did not have ASCII-armored keyrings at hand.  It also adds a
test for this so that we can catch it earlier next time.

Two issues with the test:

  1. For some reason, `check_id ()' doesn't work with the second ID
     that's commented in `keyring.c', although it should.  Actually, I
     have the exact same test in Scheme and that one works.  So there
     must be something fishy going on, but I couldn't find out what.

  2. There's a memory leak in `cdk_keydb_get_pk ()':

     3,466 (24 direct, 3,442 indirect) bytes in 2 blocks are definitely lost in loss record 4 of 4
        at 0x401D4B0: malloc (vg_replace_malloc.c:149)
        by 0x420C7F3: (within /usr/lib/libgcrypt.so.11.2.2)
        by 0x420CA60: gcry_malloc (in /usr/lib/libgcrypt.so.11.2.2)
        by 0x420CCDC: gcry_calloc (in /usr/lib/libgcrypt.so.11.2.2)
        by 0x402BBA5: cdk_calloc (main.c:163)
        by 0x402E33A: cdk_kbnode_new (kbnode.c:41)
        by 0x4030758: cdk_keydb_get_keyblock (keydb.c:1715)
        by 0x4031953: cdk_keydb_search (keydb.c:938)
        by 0x40325D7: cdk_keydb_get_pk (keydb.c:1268)
        by 0x4029878: gnutls_openpgp_keyring_check_id (extras.c:103)
        by 0x8048921: doit (keyring.c:163)
        by 0x8048B44: main (utils.c:148)

     Fixing it is left as an exercise to the reader.  :-)

     Also, for some unknown reason, Valgrind doesn't show the above leak
     when just run from `make check'.

Thanks,
Ludovic.

PS: BTW, how's Git going?  :-)


ChangeLog entry:

	* libextra/openpgp/extras.c (gnutls_openpgp_keyring_import):
	Fixed again, for raw keyring import (ASCII keyring import
	untested).

	* configure.in: Added `tests/openpgp/Makefile'.
	* tests/Makefile.am (SUBDIRS): Add `openpgp' when
	`ENABLE_OPENPGP' is true.

I thought the problem would be fixed with the new opencdk code. I
might mix up things so, so please could you explain again what the

Actually I already documented it in the TODO file, but the fix
is a little tricky because it is not obvious where the leak occurs.

I forgot to ask how the openpgp test environment usually looks like?
Do you use the included opencdk package for tests or an external? If
you use an external, I would suggest to use 0.6.1 because it contains
minor enhancements and bug fixes.

Hi!

I checked your test (keyring.c) and the raw_keyring
string was malformed. It contained a \0 somewhere after
the first Dr. Who key. (To confirm this, dump the raw
data on stdout/stderr and use pgpdump raw_data. You will
notice an premature EOF)

I corrected it and now it works without any problems. I
attached the corrected test file for test purposes.

Raw-keyring import does not work without the patch.  Please, run the
test case I sent (part of the patch).

Funny to document a leak.  :-)

I use the included OpenCDK which is supposed to work fine for GnuTLS
purposes.

Thanks,

Cool, thanks!

Can you check in the whole patch, i.e., keyring import-fix plus new test
case (your version)?

Thanks,

I did, but _after_ I applied the patch for extras. I wasn't aware
the raw import did not work, so the patch makes sense. Thanks.

Yes and no. If somebody reports a leak and you cannot fix it, you
need at least to document it, no?

IMHO it's the easiest solution, all I need to do is to keep the source
in the opencdk folder in sync with the latest opencdk release.

No problem. I wanted to write a test myself and now I can

Yes.

Simon, is it OK that I will check in the changes? None of the patches
touches the core code, if you are concerned of the stability. Plus
I already run the tests and made a successful connection to test server.

Message-ID: <9e0cf0bf0705131241i637dce16t3772ed0e3528014@mail.gmail.com>

Hello,

An initial version of gnugls-pkcs11 is available for testing.
It should provide a simple API to access PKCS#11 cryptographic tokens.

I tried to keep the API as simple as I could, by copying some of
gnutls "simple" interface, although I think gnutls interface should be
modified to eliminate the requirement of global variables, and the
programmer to develop a specific code if it uses an engine.
I also cleaned the cli so it will only test the pkcs11 implementation,
I hope to clean this further.

The implementation allows to use several providers at the same time,
support session expiration, token request (if needed), several tokens
at the same time, detect a token if it is removed and insert to a
different slot, loading certificate authorities from token and much
more.

You can download gnutls-pkcs11 from:
http://alon.barlev.googlepages.com/gnutls-pkcs11-0.01.tar.bz2

Generated documentation is available at:
http://alon.barlev.googlepages.com/gnutls-pkcs11-0.01-docs.tar.bz2

In order to compile the engine, you should use the following components:
1. http://josefsson.org/gnutls/releases/pkcs11/gnutls-1.7.8.p11.2.tar.bz2
2. http://www.opensc-project.org/files/pkcs11-helper/pkcs11-helper-1.02.tar.bz2

Configure gnutls with --without-pkcs11-scute, I hope that next branch
will have this off by default.

In order to test gnutls-pkcs11 I use:
$ ./configure GNUTLS_CFLAGS="-I${GNUTLS_HOME}/include"
GNUTLS_LIBS="-L${GNUTLS_HOME}/lib -lgnutls"

In order to test, use:
LD_LIBRARY_PATH="${GNUTLS_HOME}/lib" src/gnutls-pkcs11-cli
--add-provider=/usr/lib/pkcs11/  --cmd=ids

You will get available certificates that may be used, look at the:
PKCS#11 ID: XXXX

Now:

$ LD_LIBRARY_PATH="${GNUTLS_HOME}/lib" src/gnutls-pkcs11-cli
--add-provider=/usr/lib/pkcs11/  --cmd=connect
--host=localhost --port=5556 --pkcs11-id='XXXX'

Where XXXX is the id selected from the list. Please note the single
quote, it is required so sh will not mess with the backslashes.

If it does not work for you, please add --debug=5 and send me the log.

Any comments/suggestions are appriciated!

Best Regards,
Alon Bar-Lev.

Sure, if it just touches opencdk or the opencdk glue in gnutls without
changing any APIs, please go ahead.

(Let's see if this message makes it to the gnutls-dev list..)

See:

http://josefsson.org/gnutls/releases/pkcs11/

The announcement (and likely, this message too) didn't make it to the
gnutls-dev list because I recently changed mail server to one that
doesn't have any reverse-dns.  Sigh...

There is a branch in CVS too:

http://cvs.gnupg.org/cgi-bin/viewcvs.cgi/gnutls/?root=GNU+TLS+Library&only_with_tag=gnutls_1_7_8_with_pkcs11

I'm going to set up a Git server for it today.

The application calls gnutls_certificate_free_credential, so it should
be able to call another function at the same place to clean up the
resources that itself allocated.  This seems a better API separation to
me: the application is responsible for deallocating what it allocates,
and GnuTLS deallocate what it has allocated.

That API could be the same with my approach.

However, I don't think strongly about this, and when I get around to
changing the API to be certificate_credential-specific rather than
session-specific, we'll see how it works out.

I've added this too.

This seem to be bloat to me, since it offers no additional
functionality.  Applications can cleanup resources when they deinit the
particular GnuTLS session that uses the sign callback, can they not?

I'm considering to change the APIs (see below), so I didn't want to
spend time discussing the changes for the next release now (otherwise I
wouldn't have time to release it today).

When I have time to write down my ideas about the changes that are
necessary -- the sign callback should be set per
gnutls_certificate_credential_t and not per session -- we can discuss
the new API.  However, I'm going to be busy for about 10 days so nothing
will happen until after that.

What should be possible for you with the upcoming p11.2 release is to
write a PKCS#11 interface that can be invoked via the sign callback.  I
hope that you will be able to test signing via the callback and some
PKCS#11 provider that you have until I come back.  Then we your
experience and the new API, finalize it and bring it back into the 1.7.x
branch.

Thanks,
Simon

I think Timo took care of this.

I'm talking with savannah.gnu.org about hosting it.  I'm not yet sure
how I want things to work.  I would prefer to push my local git
repository to josefsson.org and savannah and repo.or.cz can mirror it,
but maybe that is too much work.

Cool!  I'm able to authenticate to the test.gnutls.org test server using
my brand new Swedish NIDEL ID card using the OpenSC PKCS#11 provider.

Pkcs11-helper needs the following patch to compile configured with

./configure --without-crypto-engine-openssl --disable-openssl

though.

Subject: [gnutls-dev] Gnutls 1.7.8.p11.2
Message-ID: <87r6pnqwpr.fsf@mocca.josefsson.org>

Here is the third release on the PKCS#11 branch.  This is only minor
fixes.  I'm thinking of changing the API so that the sign callback is
set on the credential and not on the session instead, which appears to
be cleaner API-wise.  I don't have time to implement that today, though,
and I won't have time to work on it more until Monday 21:th, but I
wanted to get this release out the door anyway.

The NEWS entry is:

* Version 1.7.8.p11.2 (released 2007-05-11)

** Make Scute dependency optional.
Suggested by Alon Bar-Lev.  When Scute is not found, gnutls-cli will
not support the PKCS#11 interface.

** Add void* parameter to sign callbacks.
Suggested by Ludovic Court?s and Alon Bar-Lev.  This changes the
get/set_sign callback APIs.

** Rename gnutls_set_sign_function to gnutls_x509_sign_callback_set,
** and gnutls_get_sign_function to gnutls_x509_sign_callback_set.
The functions are X.509 specific, and the name should reflect that.
Ideally, these callbacks function should be set in the
gnutls_certificate_credentials_t structure since there is where the
private key is set.  However, the implementation to do that is more
complicated.

** API and ABI modifications:
gnutls_set_sign_function: REMOVED, renamed to gnutls_x509_sign_callback_set.
gnutls_x509_sign_callback_set: NEW, renamed from gnutls_set_sign_function.
gnutls_get_sign_function: REMOVED, renamed to gnutls_x509_sign_callback_get.
gnutls_x509_sign_callback_get: NEW, renamed from gnutls_get_sign_function.
gnutls_sign_func: CHANGED, added userdata type.

Warning!  This is even more experimental than the experimental 1.7.x
branch.  However, the changes compared to 1.7.8 are intentionally kept
minimal, to facilitate easy merging later on.

The support is limited to:

1) Optional support for build-time linking to the PKCS#11 provider
   scute, see http://www.scute.org/.

2) Retrieving trusted CA certificates from the PKCS#11 provider.  (If
scute is installed.)

3) Retrieving user certificates from the PKCS#11 provider.  (If scute is
installed.)

4) Provide a callback to perform signing operations.

5) Provide an API to perform PKCS#11 signing via the PKCS#11 provider.

You can test the sign callback infrastructure separately, if you want to
implement your own PKCS#11 interface or similar.

To test the PKCS#11 integration, you'll need to build scute 1.1.0, and
set it up (try using it in mozilla), which requires some reading, see
the Scute manual.  I generated new keys on an OpenPGP smartcard with
gpg2 --edit-card and gpgsm-gencert.sh, then signed the CSR with certtool
using the GnuTLS test CA, and imported the certificates using 'gpgsm
--import'.

If someone can explain to me how I can test other PKCS#11 providers, I
can test them too.  Supporting the NSS soft token provider is an
important target.

The gnutls-cli tool in this release automatically import all CAs from
Scute, and will load the user certificates too, and invoke Scute for
signing.  Here is an output from running it against the GnuTLS test
server:

Great!
Please try Scute... I've never tried it before... It should use
protected authentication, it means that the program should not ask you
for PIN but the gnupg pinentry should pop up.

Some questions:

1. Do you have any comments regarding the API?

2. Do you want me to add the gnutls interface to pkcs11-helper (as in
OpenSSL case) or leave it as a separate module?

3. Do you think there is advantage of creating subset API of
pkcs11-helper available (current state), or have the developer access
pkcs11-helper directly and provide some utilities for GnuTLS
environment (as in OpenSSL case).

Oops... Long time since I tried GnuTLS only... :)

Hi,

Any idea how we can get an ASCII-armored keyring so that we can test it
as well?

I was (presumably) able to create one with:

  $ gpg --keyring ./openpgp-keyring.gpg --export -a > t

But then `gpg' was unable to show me its contents:

  $ gpg --keyring ./t -a --list-keys
  [Lists ~/.gnupg/pubring.gpg...]
  gpg: [don't know]: invalid packet (ctb=2d)
  gpg: keydb_search_next failed: invalid packet

I was able to open it using the GnuTLS keyring API, though, which is
encouraging.

Thanks,
Ludovic.

A keyring must not be ASCII armored and using the transfer format
directly as the keyring is not suggested for future compatibility
reasons.

To show the content of an exported keyring, simply run

  $ gpg ./t

To make sure I understand you. You try to check than an
armored key file is correctly formatted and contains
valid openpgp keys?

We should either write a small helper program or a handy
function.

It doesn't seem to work.  Here is what happens.  Any ideas?

I haven't really made up my mind about how things should work here.

One concern I have is any OpenSSL dependency.

Another concern is that I would like GnuTLS to include some native
PKCS#11 interface, to support the OpenPGP card, GNOME Seahorse, and
possibly NSS's provider directly.  I think it doesn't make sense for
GnuTLS to handle pin's etc.  I think GnuTLS should assume the PKCS#11
provider takes care of PIN entry internally.  (Although I don't know how
the NSS provider works.)  I don't yet know how this is best implemented.
Including a copy of pkcs11-helper and your gnutls-pkcs11 library
(assuming the copyright and license situation is suitable) is a
possibility.

Yes...
It seems that it forks.
After fork, I must call C_Initialize/C_Finalize again to cleanup state
in child. This is part of PKCS#11 spec.
Nobody thought about a provider that doing fork()... :)
So I guess scote should have somekind of recursion protection on
C_Initialize/C_Finalize and also have reference counter so that
multiple call of C_Initialize will be allowed.

Why not just maintain it as sepearate component?

I suppose this is just PKCS#11 internal stuff, and I hope you will solve
it.  If I can assist in testing anything, let me know.

pkcs11-helper seem to link to OpenSSL by default.  As far as I
understand, distributions cannot distribute packages that links
pkcs11-helper together with gnutls via your gnutls-pkcs11 legally.
Perhaps gnutls and/or gnutls-pkcs11 could check whether pkcs11-helper
picks up OpenSSL, and if so, emit an error message.

They are separate components, see the pkcs11-branch: there is a
standalone libgnutls-pkcs11 library (see the top-level pkcs11/
directory) that provides a simple PKCS#11 interface to Scute via the
header gnutls/pkcs11.h.  Applications can chose to implement the sign
callback using GnuTLS's pkcs11 library, but then they'll have to link to
it, or your library, or some other library (that may use CAPI or
whatever).

will be able to solve it.

I don't understand...
The OpenSSL stuff is not used, I can provide an engine for GnuTLS
inside the gnutls-pkcs11.
Even if it linked it is not used.

I don't understand...
The simple scute implementation is irrelevant for 99.999% of users.
And if application chooses to use PKCS#11 it can also chose to add a
library to its linkage.

Hmmm...
You can try to configure pkcs11-helper with --disable-threading
--disable-slotevent, I guess it will stop fixup the fork()
automatically.

Yup, right.

The license is on the source code, and by using the OpenSSL API I
believe the FSF would consider pkcs11-helper to be a derived work from
OpenSSL, and thus GPL-incompatible.  This would have to be confirmed
with the FSF, though.

That may be true, but as far as I can tell, the simple scute
implementation doesn't harm anything else, so I don't see a problem with
it.

Yes, that is the point.  Applications that wants to support external
signing will have to do something extra.  That can link to your
gnutls-pkcs11 library, or my scute gnutls-pkcs11 library (there appears
to be a naming conflict here though), or something else, or even
implement everything by itself.  It is even possible to do all at at the
same time, if properly multiplexed by the application.  The nice
property is that the core GnuTLS library doesn't need to know about
this.

Hello Marcus,

The sequence is as follows:
1. Application calls C_Initialize() of some providers.
2. Application fork()
3. Application must call C_Initialize() at child, as the spec
instructs, so child environment will be complete.
4. Application wishes to do something else in this child, so it C_Finalize()
5. Parent can access PKCS#11 token.
6. Child does not.

In your case you fork, so automatically you get C_Iniitalize(),
C_Finalize() at child, and it seems that somehow it makes the parent
not working?

Best Regards,
Alon Bar-Lev.

No... since the OpenSSL is not used in the solution with GnuTLS, it is
not derived work.

OK... Whatever...
1. How user can chose which API to select?
2. You need to sync the API.
3. Working PKCS#11 with only one provider is irrelevant... This is not
why PKCS#11 was introduced.

I don't understand your desire to push a library which is not exactly
doing anything.
Also calling yours gnutls-pkcs11 is misleading, since you really gnutls-scute...

Hi,

The test case I posted, `keyring.c', only checks whether a raw keyring
can be imported.  It would be nice to augment the test so that it checks
whether ASCII-armored keyrings can be imported as well (i.e., passing
`GNUTLS_OPENPGP_FMT_BASE64' to `gnutls_openpgp_keyring_import ()').

To that end, we need an ASCII-armored keyring.  I was able to create one
with GPG and to load it with `gnutls_openpgp_keyring_import ()', but I
did not managed to get GPG to show me its contents, until Werner Koch
showed how to do it.

The issue now is that "gpg --export -a < ./keyring.gpg > ./keyring.asc"
includes my own keyring (from `~/.gnupg/pubring.gpg') into its output.

Thanks,
Ludovic.

You mean future GPG versions may not be able to import/export keyrings
encoded in the raw or "ASCII armor" formats, is that correct?

Right, thanks!

I was able to work around it this way:

  $ gpg --keyring ./openpgp-keyring.gpg -a --export A7D93C3F CCC07C35 > t

(Where `openpgp-keyring.gpg' is the raw keyring we use in `keyring.c'.)

There's one last fix need for ASCII-import to work: `cdk_stream_close ()'
must not be called when `cdk_keydb_new_from_stream ()' succeeds
(patch attached).  I tested it (ASCII-import, followed by `check_id ()'
calls) from a Guile script and it does work with the patch applied
(segfaults otherwise).

BTW, you removed the repeated `if (err) { gnutls_assert () ... }' that
appeared in my patch.  I don't think this is a good idea: having
repeated `gnutls_assert ()' calls allows one to pinpoint the exact
source of a failure.

Also, please do update the `ChangeLog' file, it makes it easier to
follow what goes on.

Thanks,
Ludovic.

Did it ask you for PIN in application or just see the gnupg pinentry?
(expected: pinentry only).
If you run the gpg-agent and then the test program twice, you should
be prompted by pinentry only at first run, please verify.
What happen if you remove and insert token? I hope you will be
prompted for PIN at next run.
What happen if you remove the token and run the test program? I guess
you should be prompted by application to insert your card, but maybe
pinentry will prompt you... The later will happen if scute does not
manage dynamic objects.

Actually we do not need an armored keyring, just a file with armored
keys. The GnuTLS openpgp support makes no real difference between
a key file and keyring. It's only important that the file contains a
sequence of openpgp packets which form a valid key {public or private}.

Because keyrings formats are not described in the openpgp message
format. It's up to the implementation to define a suitable format.
But, as Werner pointed out, transferable keys needs to follow the
openpgp format.

Hi!

I finally managed it to run some opencdk tests on a Windows box
and it seems that the code needs to be more W32 specific fixes :-(.
In other words, I don't believe that the openpgp support is working
for the gnutls/w32 binary.

Could anybody test the w32 build with the included opencdk code?

But I managed to fix all memory leaks valgrind reported. Thank

Hello,

Ronny Adsetts has been plagued by an exim4 crash in the gnutls code
when receiving mail from a specific server. - It seems like gnutls
does not like the client certificate and crashes. The complete bug
history is on , featuring strace output
and a tcpdump capture.

Ronny has been able to get the following backtrace, with the segfault
happening due to null-pointer dereferencing in _gnutls_read_uint16.

I do not know how debug this efficiently, the machine in question is
a production machine and the bug only occurs on specific third party
hosts connecting.

TIA for your help. This is gnutls 1.4.x, BTW)

      ^^^^^^^^^^^^^^^^^^^^^^^

Interesting, data is NULL here, as invoked from this function:

> #2  0x00002ba3e84171e9 in _gnutls_recv_client_kx_message (session=0x629e10)
>     at gnutls_kx.c:333

The function reads:

      ret =
	_gnutls_recv_handshake (session, &data,
				&datasize,
				GNUTLS_HANDSHAKE_CLIENT_KEY_EXCHANGE,
				MANDATORY_PACKET);
      if (ret < 0)
	return ret;

      ret =
	session->internals.auth_struct->
	gnutls_process_client_kx (session, data, datasize);
      gnutls_free (data);
      if (ret < 0)
	return ret;

Reading the source for _gnutls_recv_handshake, it seems to be possible
for it to return >= 0 if the code received a
GNUTLS_HANDSHAKE_CLIENT_HELLO or GNUTLS_HANDSHAKE_SERVER_HELLO packet.
I'm not 100 % certain of this though.

If you can reproduce the crash in gdb, try getting a backtrace using 'bt
full', and invoke 'up' until you are in the _gnutls_recv_handshake stack
frame, then 'p recv_type'.  If it is indeed
GNUTLS_HANDSHAKE_CLIENT_HELLO or GNUTLS_HANDSHAKE_SERVER_HELLO then I
think we have diagnosed the cause.

It may be that the client got confused and started sending client
hello's all over, and this confused the GnuTLS state machine.  Of
course, it shouldn't be possible to crash it.

Debugging exactly why the other end sends these funny messages would be
the next step, I'm not sure that if we would fix the crash that the
hosts will be able to handshake properly.

Any chance to contact the remote host to find out what software it is
using?

Message-ID: <200705160106.19537.victor@inl.fr>

Hi,

I'm trying to understand how to use gnutls_certificate_verify_peers2() and how 
the function works. I think that there is a bug in x509 certificate code:

[gnutls/lib/gnutls_x509.c, near line 181]

   ret = gnutls_x509_crt_list_verify(..., status);
   ...
   if (ret < 0) { ...; return ret; }
   return 0;

[gnutls/lib/x509/verify.c, near line 784]

   int gnutls_x509_crt_list_verify(...)
   {
      *verify = _gnutls_x509_verify_certificate(...);
      return 0;
   }


_gnutls_x509_verify_certificate() return code (stored in *status) is never 
checked :-/

Problem: gnutls_certificate_verify_peers2() returns 0 even if the certificate 
is invalid :-/

Solutions:
 * Workaround: in application code: 
     * check status value: if (ret < 0 || status != 0) error!
     * NEVER use gnutls_certificate_verify_peers()
 * Fix gnutls: use status value, something like:
      if (status != 0) { gnutls_assert(); return -1; }

This bug looks to be a security bug :-/

The tcpdump's are only in one direction, and ethereal can't decode it as
a SSL stream then...  It would be useful to capture both what is sent
and what is received.  Now it appears to be only what the other end is
sending.

I'm still not sure that it's a bug but looks to be a problem in the 
documentation.
-----
   int gnutls_certificate_verify_peers2(
       gnutls_session_t session, unsigned int * status); 

ARGUMENTS 
   gnutls_session_t session is a gnutls session 
   unsigned int * status is the output of the verification

DESCRIPTION 
   This function will try to verify the peer's certificate and return its
   status (trusted, invalid etc.). (...)
   Returns a negative error code on error and zero on success. 
-----

What is "a success" in this case? In my mind, success means that the 
certificate is valid but it looks like I'm wrong.

A "success" is that the verification operation worked correctly, but the
_status_ of that successful verification (which can be failure) is
reported through the status output parameter.

Frankly, I find the old gnutls_certificate_verify_peers() function more
logical, but Nikos wanted to deprecated it in favor
gnutls_certificate_verify_peers2().  The use of a bitmap'ed status type
like gnutls_certificate_status_t may be problematic though (limit us to
32 different kind of failures).

Suggestions on how to improve the documentation would be appreciated.

Ideally, all the X.509 stuff should be moved to a different library.
GnuTLS's current certificate verifier fails on some chains, see the
PKITS self-tests:

Hello,

Since opencdk 0.6.x introduces a new soname, the symbol versioning
info in src/libopencdk.vers needs to be bumped to stay useful.
(Otherwise a program accidentally liked against opencdk 0.5.x and
opencdk 0.6.x at runtime will crash.)

You need to define 'ssize_t' somehow.  For example, build using
'./configure CFLAGS=-Dssize_t=long'.

I applied the patch, but I still have a little problem.

For my tests I use:

./gnutls-cli --pgpkeyfile openpgp/cli_sec.asc \
 --pgpkeyring openpgp/cli_ring.asc \
 --pgpcertfile openpgp/cli_pub.asc --port 5556 test.gnutls.org

(I generated the "cli_ring.asc" file with
 cp cli_ring.gpg /tmp
 gpg --homedir . --no-options --no-emit-version \
     --keyring cli_ring.gpg -a --export > cli_ring.asc
)

But I'm a little confused because the import
code, with the armor flag, is never called.
That's why I also did not detect the problem the first
time. Did I forget to set an option to assure the code
will be used?

Actually the function code also contains another error.
Due to the nature of cdk_keydb_new_from_stream(),
the function do not close the stream at the end, cdk_keydb_close(),
itself, so we need to store it separately and close it
later.

I already modified the code but I still need to test it.

Sorry for the unnecessary mails, I accidentally

Again I'm sorry, now it works again.

Hmm, good point!

There's still something wrong with what you checked in, though:

  err = cdk_stream_tmp_from_mem (data->data, data->size, &input);
  if (!err)
    err = cdk_stream_set_armor_flag (input, 0);
  if (!err)
    err = cdk_keydb_new_from_stream (&keyring->db, 0, input);  
  if (err)
    {
      cdk_stream_close (input);
      gnutls_assert ();
    }

That won't work if `cdk_stream_tmp_from_mem ()' returns an error.

How about ChangeLog entries BTW?

> I already modified the code but I still need to test it.

Please, run the tests in Guile-GnuTLS 0.1 [*].  You need Guile 1.8 and
then run "make check".

I'm currently unable to compile GnuTLS from HEAD because of something
fishy going on with Gnulib:

  $ make CFLAGS='-g -Wall' -j2
  make: *** No rule to make target `gl/m4/getpass.m4', needed by `Makefile.in'.  Stop.

  $ find -name getpass.m4
  ./lgl/m4/getpass.m4

  $ grep -r getpass gl/
  gl/Makefile:# Reproduce by: gnulib-tool --import --dir=. --local-dir=gl/override --lib=libgnu --source-base=gl --m4-base=gl/m4 --doc-base=doc --aux-dir=. --avoid=snprintf --avoid=vasnprintf --makefile-name=gnulib.mk --libtool --macro-prefix=gl arpa_inet fdl gendocs getaddrinfo getline getpass gpl inet_ntop inet_pton lgpl maintainer-makefile readline
  gl/Makefile:    $(top_srcdir)/gl/m4/getpass.m4 \

  gl/Makefile:    getline.c getpass.c inet_ntop.c inet_pton.c readline.c \
  gl/Makefile:include ./$(DEPDIR)/getpass.Plo
  gl/Makefile.in: $(top_srcdir)/lgl/m4/getpass.m4 \

So, for some reason, the generated `Makefile' gets the path to
`getpass.m4' wrong, although `Makefile.in' has the right one.

Running `autoreconf', `automake' or `gnulib-tool --update' doesn't
help.  Any idea?

Thanks,
Ludovic.

Why? input is set to NULL in the function and thus cdk_stream_close
does nothing because the param is NULL.

IMHO the ChangeLog entries are generated from the CVS commit logs.

I think 'autoreconf -fvi' should help.  You could try 'cvsco' from
cvs-utils too, it cleans up everything to get a fresh checkout.

`cdk_keydb_new_from_stream ()' does not always initialize INPUT to NULL
on error, at least not in the OpenCDK currently available in HEAD:

  cdk_error_t 
  cdk_keydb_new_from_stream (cdk_keydb_hd_t *r_hd, int secret,
                             cdk_stream_t in)
  {
    cdk_keydb_hd_t hd;

    if (!r_hd)
      return CDK_Inv_Value;
    
And `cdk_stream_close ()' returns an error if STREAM is NULL:

  cdk_error_t
  cdk_stream_close (cdk_stream_t s)
  {
    struct stream_filter_s *f, *f2;
    cdk_error_t rc;

    if (!s)
      return CDK_Inv_Value;

Well, we don't check its return value...

It turns out that they are not automatically generated.

if cdk_stream_tmp_from_mem returns != 0 the
"if (!err)" expression fails and the keydb function is not called.

That's right, but with the current code cdk_keydb_new_from_stream is
never called. It would be only called if there is _no_ error!

The patch is not very elegant, it works but I guess I shall
cleanup it up.

I've done a quick review of past patches.  Here's what should be
applicable (since most of the messages contain individual patches and a
description of the problem, I thought they might be easier to review
than a single big patch):

  * raw OpenPGP keyring import (doesn't address ASCII import since this
    requires the recent additions in OpenCDK)

    http://article.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/1873

  * trivial bug in `gnutls_certificate_set_openpgp_key ()'

    http://article.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/1858

  * TLS 1.2 RSA/DSA signature verification bug

    http://article.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/1760

  * TLS 1.2 handshake bug

    http://article.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/1749

  * off-by-one in `gnutls_openpgp.c'

    http://article.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/1669

  * small OpenPGP API inconsistencies

    http://article.gmane.org/gmane.network.gnutls.general/591


Unfortunately, an interesting bug fix may not be applicable due to
API/ABI-breaking issues (although it is unclear whether there really is
a problem since only internal functions are changed):

  * allow import of ASCII-armored OpenPGP private keys

    http://article.gmane.org/gmane.network.gnutls.general/617
    http://article.gmane.org/gmane.network.gnutls.general/645

Let me know if I can help better.

BTW, is the Git-on-Savannah project suspended for now?

These two looks fine.

1.6.x doesn't support TLS 1.2, so these doesn't matter, right?

These seems fine too.

This one seems too big...  I think we could start pre-testing of 1.7.x
targetting a stable 1.8.0 soon instead.

Thanks for compiling things separately, very useful!

It didn't work out with Savannah for now (they don't want to mirror
other git repositories), but I'm working on getting a mirror up at
repo.or.cz now.

Yeah, if you think time has come, then that would be easier.

Alright.

I'd like to have the Guile bindings integrated by the time you release
1.8.  So I'll start the integration work from your Git repository when
it's available.

Thanks!

Subject: [gnutls-dev] Libtasn1 0.3.10
Message-ID: <87tzu1ujgv.fsf@mocca.josefsson.org>

Second release from GIT instead of CVS, mostly as practicing before
releasing GnuTLS 1.7.x for the first time from GIT.

Libtasn1 is a standalone library written in C for manipulating ASN.1
objects including DER/BER encoding and DER/BER decoding.  Libtasn1 is
used by GnuTLS to manipulate X.509 objects and by Shishi to handle
Kerberos V5 packets.

Version 0.3.10 (released 2007-05-25)
- Update gnulib files.

Commercial support contracts for Libtasn1 are available, and they help
finance continued maintenance.  Simon Josefsson Datakonsult, a
Stockholm based privately held company, is currently funding Libtasn1
maintenance.  We are always looking for interesting development
projects.  See http://josefsson.org/ for more details.

This is the first release from the GIT repository.  I push it to
.  Currently the old CVS repository
doesn't contain the latest changes, I'm not sure how to arrange
exporting git->cvs... possibly, we'll have to deprecate the
cvs.gnupg.org CVS repository and refer CVS users to a git-cvsserver
repository.  Opinions about this are appreciated.

Note that the GnuTLS 1.7.x branch is NOT what you want for your stable
system.  It is intended for developers and experienced users.

* Version 1.7.10 (released 2007-05-25)

** New API functions to extract DER encoded X.509 Subject/Issuer DN.
Suggested by Nate Nielsen .

** Update of gnulib files.

** GnuTLS is now developed in GIT instead of CVS.
See  for a public repository.

** API and ABI modifications:
gnutls_x509_crt_get_raw_issuer_dn: ADD.
gnutls_x509_crt_get_raw_dn: ADD.

I can't find it either.

novel at underworld:~/gnutls-1.7.10 %> find . -name "opencdk.h*"
novel at underworld:~/gnutls-1.7.10 %>

Maybe I'm missing something obvious? But gnutls 1.7.10 doesn't build
anyway, because of the missing opencdk.h.

Thanks for the report, I'll release 1.7.11 shortly to fix this.

Message-ID: <87hcpzeenb.fsf@mocca.josefsson.org>

This is from the GIT repository that I push to
.  The old CVS repository at
cvs.gnupg.org doesn't contain the latest changes, and I'm not sure how
to arrange back-porting of changes made in git back into CVS...
possibly, we'll have to deprecate the cvs.gnupg.org CVS repository and
refer CVS users to a git-cvsserver repository.  Opinions about this are
appreciated.

Note that the GnuTLS 1.7.x branch is NOT what you want for your stable
system.  It is intended for developers and experienced users.

* Version 1.7.11 (released 2007-05-26)

** Include opencdk.h in the release.
Reported by Roman Bogorodskiy .

** API and ABI modifications:
No changes since last version.

Here are the compressed sources (4.3MB):

Improving GnuTLS is costly, but you can help!  We are looking for
organizations that find GnuTLS useful and wish to contribute back.
You can contribute by reporting bugs, improve the software, or donate
money or equipment.

Commercial support contracts for GnuTLS are available, and they help
finance continued maintenance.  Simon Josefsson Datakonsult, a
Stockholm based privately held company, is currently funding GnuTLS
maintenance.  We are always looking for interesting development
projects.  See http://josefsson.org/ for more details.

Subject: [gnutls-dev] Things to do before next stable release?
Message-ID: <87bqg7ed65.fsf@mocca.josefsson.org>

I think 1.7.x now contains a lot of stuff that we should release as a
stable release, for example:

* TLS 1.2 support (although protocol not finalized in the IETF yet).

* Proxy certificate support.

* Signing using RSA-SHA256/384/512.

* New APIs to print textual representation of certificates.

* Support for 'otherName' SAN.

* Support for supplemental data (RFC 4680).

* Support for tls-authz.

* New APIs to iterate through supported algorithms.

Plus many, many bug fixes and other improvements of existing code.

Initially I wanted to wait for TLS 1.2 to stabilize until we would
release 1.8.0, although that seems to take longer than expected.

I think we could release 1.8.0 as-is, with TLS 1.2 disabled as a default
protocol, and with a release note saying that the TLS 1.2 stuff is
subject to change incompatibility if the IETF changes the protocol.

Can anyone think of other things to do before releasing the 1.7.x branch
as a new stable 1.8.0?

Come to think of it, the amount of new features (especially TLS 1.2) may
warrant calling this release 2.0.0.  What do you think?

I'll try to go over a 'diff -r gnutls_1_6_2 gnutls_1_7_11' to see if
there is some pending work that I've forgotten about.

Patch installed on 1.6.x.

I'd like to incorporate your self-test for the 1.7.x branch, though, but
that requires that you assign the copyright on the self test to the FSF.
Is that ok with you?  If so, I can send you the proper forms.

Thanks,

Patch installed on 1.6.x branch, even though it is close to the ~10
lines limit that would require copyright assignments.  The self-test is
longer than 10 lines, though, and papers are required for it.  I'd like
to include it in 1.7.x with your co-operation, see the response to your
other report.

Thanks,
Simon

Oh, right, definitely.  Thanks for reminding me.  I'll try to get 1.6.3
out tonight, then I'll work on reworking the sign callback API, and wait
for your review of it.  After that, we can move it into the 1.7.x
branch.  I think the sign callback work is important enough to hold up
the next stable branch.

Note to self, my todo-list before releasing 1.8.0 right now is:

* Fix sign callback API to be per-credential rather than per-session.

* Check copyright papers for everyone who contributed during the 1.7.x
  phase (I opportunistically installed some fixes after confirming with
  authors that they were sending copyright assignments, although I have
  not verified that the assignment were actually received).

* Make sure the stuff in the GIT repository (i.e., all recent work) is
  available through CVS, either through back-ports to the old server or
  a git-cvsserver approach.

No, it just means that I haven't gotten around to it.  It has been
installed on the 1.6.x branch now.

Thanks,

Subject: [gnutls-dev] GnuTLS 1.6.3
Message-ID: <87fy5jpa83.fsf@mocca.josefsson.org>

I am happy to announce GnuTLS 1.6.3!

This is a bugfix-only release on the stable branch.  This version is
what we recommend for those who need a stable version of GnuTLS.

GnuTLS is a modern C library that implement the standard network
security protocol Transport Layer Security (TLS), for use by network
applications.  GnuTLS is developed for GNU/Linux, but works on many
Unix-like systems and comes with a binary installer for Windows.

   Warning!  GnuTLS uses OpenCDK for OpenPGP parsing.  Recently, a new
   branch of OpenCDK has been released by Timo as 0.6.x.  Unfortunately,
   the new branch is not backwards API/ABI compatible with the old 0.5.x
   branch.  The stable branch of GnuTLS do not support the newer OpenCDK
   0.6.x releases.  To be able to build GnuTLS 1.6.x, you must use
   OpenCDK 0.5.x instead of 0.6.x.  Alternatively, use the ./configure
   parameter --with-included-opencdk to use the included copy of OpenCDK
   0.5.13 for building GnuTLS, or the --disable-openpgp-authentication
   parameter to disable OpenPGP altogether.

* Version 1.6.3 (released 2007-05-26)

** New API functions to extract DER encoded X.509 Subject/Issuer DN.
Suggested by Nate Nielsen .  Backported
From the 1.7.x branch, see
.

** Have PKCS8 parser return better error codes.
Reported by Nate Nielsen , see
 and
.

** Fix mem leak for sessions with client authentication via certificates.
Reported by Andrew W. Nosenko , see
.

** Fix building of 'tlsia' self test.
Earlier some gcc are known to build tlsia linking to
$prefix/lib/libgnutls-extra.so rather than the libgnutls-extra.so in
the build directory, even though command line parameters look OK.
Changing order of some parameters fixes it.

** API and ABI modifications:
gnutls_x509_crt_get_raw_issuer_dn: ADD.
gnutls_x509_crt_get_raw_dn: ADD.

Improving GnuTLS is costly, but you can help!  We are looking for
organizations that find GnuTLS useful and wish to contribute back.
You can contribute by reporting bugs, improve the software, or donate
money or equipment.

Commercial support contracts for GnuTLS are available, and they help
finance continued maintenance.  Simon Josefsson Datakonsult, a
Stockholm based privately held company, is currently funding GnuTLS
maintenance.  We are always looking for interesting development
projects.  See http://josefsson.org/ for more details.

Hi Ludovic.  I am sorry these patches didn't make it for 1.6.3, but I
had to cut the line somewhere, and I felt these hadn't been reviewed
sufficiently for back-porting yet.  We can still make a 1.6.4 soon if
you want.

Yes, I think we should push out 1.8.0 (or 2.0.0) within a few weeks or
so, if we can settle all open issues with it.  Perhaps that would be
sufficient, and you don't need 1.6.x with (only some of) the OpenPGP
fixes?  1.8 will contain the new OpenCDK 0.6.x and all the fixes.

The git repository at repo.or.cz is what I'm using for 1.7.x development
now, so you could start right now.  I don't really know much about git
though, so when you are done, you'll probably have to tell me what
commands to invoke, or we'll have to experiment, so I can pull your
changes from you into my git archive.

Btw, having the guile bindings be part of 1.8 is a good idea.  I think
it should be a blocking milestone for it.  So now my todo-list for 1.8
is:

* Integrate Guile bindings.

* Fix sign callback API to be per-credential rather than per-session.

* Check copyright papers for everyone who contributed during the 1.7.x
  phase (I opportunistically installed some fixes after confirming with
  authors that they were sending copyright assignments, although I have
  not verified that the assignment were actually received).

* Make sure the stuff in the GIT repository (i.e., all recent work) is
  available through CVS, either through back-ports to the old server or
  a git-cvsserver approach.

Hi!  Many thanks.  I have intended to send links to the OpenSSL/NSS
teams, but I haven't felt finished enough with the page to do so yet.  I
am happy to incorporate your suggestions now.

Added most of it, but I don't understand the last part -- how is the
random seed set through a 'native OS API'?  Does this refer to some NSPR
API?  Or what OS APIs do you mean?  I'm not aware of any standard APIs
for setting random seeds.

Fixed.

Good ideas, I've added this on the todo list at the bottom of the page.

Changed.

I have stumbled upon this when browsing through gnutls' Debian's bug
and it still seems to be open in 1.7.x. Due to bug-gnutls at gnu.org
being non-public I do not know whether this has already been
discussed.

Message-ID: <20070527111454.GD3725@downhill.g.la>

Hello,
this was reported by Kevin Ryde  in
. gnutls' info docs refer/include a
couple of png-images, however make install does not install them.

Since installing a file of the generic name "internals.png" directly
into /usr/share/info might result in conflicts with other software
using a dedicated subdirectory (gnutls/) seems to be the way to solve
this.

Here's the basic version 0.1 CAPI PKCS#11 plugin. It exposes
certificates (but not keys yet) and certificate trust.

I'll probably end up hosting this at code.google.com unless anyone has
better suggestions.

I recall discussing this, but I can't find it in my bug-gnutls folder.
That is all the more reason to make that alias publicly archived--I've
done so now, bug-gnutls at gnu.org should go to gnutls-dev at gnupg.org,
although I have yet to test it.

However, I'm not convinced this is the right fix.  I believe the servers
are buggy here, and changing gnutls seems the wrong response.

What we may want to do is to improve the behaviour when we encounter a
buggy server, which may include some kind of timeout or similar.
However, if the server closed the connection, I think it should be
possible to detect this, and then we can print a message.

To work on this, I need a way to reproduce it though.  Do you know of a
server that exhibit this behaviour that we can use?

Thanks,
Simon

How to deal with this properly is probably something that could be
discussed with the texinfo maintainers and/or gnu-hackers, I'll forward
the question.

Subject: [gnutls-dev] How to properly generate gnutls.pdf?
Message-ID: <20070527151003.GE3725@downhill.g.la>

Hello,

How is gnutls.pdf as included in the distribution generated? I have
tried to re-generate it after make clean but have stumbled upon a
couple of issues.

"make pdf" does not work for me, since @image is looking for .pdf:

| This is `epsf.tex' v2.7.3 <23 July 2005>
| ) localization, and turning on texinfo input format.) (./gnutls.aux)
| (./version.texi) (./my-bib-macros.texi)
| !pdfTeX error: pdfetex (file gnutls-logo.pdf): cannot find image file
| ==> Fatal error occurred, no output PDF file produced!

I can regenerate them manually with ps2pdf. After doing this I realize
that I need to run (La)TeX twice to get the references right
| [1{/var/lib/texmf/fonts/map/pdftex/updmap/pdftex.map}] [2] [-1] Chapter 1
| l.1: Undefined cross reference `Bibliography-snt'.
[1300 similar messages snipped]

So all in all it looks like I need to do this:
cd doc
make clean
for i in *eps ; do ps2pdf $i ; done
make pdf
rm gnutls.pdf
make pdf

The resulting file is more or less ok, the images are scaled wrongly
though. So, how do you do it?

thanks, cu andreas

This was fixed in 1.7.9, gnutls-logo.pdf is in CVS but wasn't
distributed.  I suspect 'make distcheck' doesn't check this because
gnutls.pdf is already available.  Are you using 1.6.x?  That version
might not have the same fix yet.

'make gnutls.pdf' in doc/, which is triggered by top-level 'make dist'.
Generally, if that doesn't work, something is wrong and should be fixed.

1.7.9 contains gnutls-logo.pdf but it does not contain the other
images in pdf format (doc/layers.png doc/x509-1.png doc/internals.png
doc/pgp1.png)

Generating them from the png input with convert (instead of using
ps2pdf on the eps figures) seems to produce satisfying results.

Ok. So it is broken due to the missing pdf-converted images.

I am not able to reproduce the "Undefined cross reference" messages with
1.7.9, so I guess I did something stupid yesterday.

Oh!  I wonder how this went by unnoticed for this long.  Probably
because gnutls.pdf is included in the distribution.  I have fixed this
now in GIT, thanks.

GnuTLS doesn't use RSA BSAFE Crypto-C or Cert-C, so if it is a problem
with those particular implementations, we are not affected.

There isn't sufficient technical information in the link you provide
that I can use to tell if GnuTLS is affected by a similar bug though.

If 1.8 is so close, then we (at least I) can probably live without
back-porting bug fixes into 1.6.  Initially, I thought 1.8 was further
away from now.

So far I just cloned it, so everything is alright.  ;-)

I'm a Git beginner as well, so we'll have to be cautious I guess.

Oh, good.

Well, let's try to make 1.8 happen as soon as possible.  If it takes
more than a month, then we can re-evaluate it.  Of course, if you want
to go through the trouble of applying the patches to the 1.6.x branch on
some git clone, I could probably learn how to pull in those changes into
my own git tree and make a 1.6.4 release of it.  Might even be useful as
git learning experience...

Great!

I'll probably start to do that on a new branch, based on the most recent
1.7.x.  The current pkcs11-branch did it per-session, and it is probably
more work involved trying to revert those changes than creating a new
branch.

> BTW, will your PCKS#11 work get into 1.8?

I'm not sure how it should be integrated.  I strongly want GnuTLS to
support OpenPGP cards easily, although I'm not sure it makes sense to
have GnuTLS provide a full-blown native PKCS#11 interface.

I'm currently not sure whether to label the support as 'libgnutls-scute'
since it links to scute at build-time, or rename it as
'libgnutls-simple-pkcs11' and add some dlopen() stuff.

One reason against calling it 'libgnutls-pkcs11' (the current name) is
that we probably won't support all variations of pkcs11 modules, with
PIN entry callbacks and so on.  On the other hand, if we can support 90%
of the common uses of PKCS#11 through a simple API, I think we should
include that into GnuTLS natively.

I suppose the options are:

1) Ship libgnutls_scute.so which links directly to scute, and provides
   some APIs like gnutls_scute_get_user_certificates,
   gnutls_scute_get_ca_certificates, gnutls_scute_sign_callback.  The
   problem here is that it is scute-specific, even though I think other
   PKCS#11 plugins may easily be supported too by just replacing
   libscute.so with something else.

2) Ship libgnutls_simple_pkcs11, or perhaps rather libgnutls_spkcs11.so,
   which would dlopen a library, and provide an API like
   gnutls_spkcs11_dlopen, gnutls_spkcs11_get_user_certificates,
   gnutls_spkcs11_get_ca_certificates, gnutls_spkcs11_sign_callback,
   possibly gnutls_spkcs11_set_pin_callback.  The problem here is that
   we might not be a full-blown PKCS#11 implementation at day one, with
   support for every variation of PKCS#11 features.  However, if we can
   support some other PKCS#11 plugins easily through this route, I think
   it is the best one.

Of course, applications can always be able to use the sign callback
interface themselves, and implement a really full-blown PKCS#11
interface using an external library, or a CrytoAPI interface, or
whatever.  Neither option 1) and 2) forces applications to use PKCS#11
or Scute through our libraries.

I think I'm leaning towards 2) and stating in the release notes that we
haven't tried all PKCS#11 provides on the earth, and that there may be
significant missing functionality, and that patches are welcome.

However, implementing the dlopen() stuff may be non-trivial, and to save
time, perhaps we could settle with a gnutls-scute solution.  It feels
somewhat sub-optimal though.

Subject: [gnutls-dev] Starting Guile integration
Message-ID: <87myzmhqxz.fsf@chbouib.org>

Hi,

I think Guile integration is starting to be in a good shape.  Basically,
all the Guile code falls into the `guile' subdirectory.  The
documentation extraction stuff is added in the `doc' subdirectory but
should hopefully not be disruptive for those Guile-less builds (and the
generated files are in `EXTRA_DIST').

I'm currently unable to run `distcheck' because building the PDF file
fails after getting a large amount of "underfull/overfull \hbox"
messages.

My Git repository is available over HTTP at:

  http://www.laas.fr/~lcourtes/software/gnutls.git

If you prefer I can also send the patches generated by
`git-format-patch' but I had the feeling that it'd kind of a spammish
approach.  ;-)

Thanks,
Ludovic.

                              ^^^^^^^^^^
This should be "disturbing".

Thanks,
Ludovic.

Thanks!  I accidentally used 'git pull' on your repository (I think I
wanted to use 'git fetch' instead), so your changes have now been
installed!

In general it looks good, but some things we need to address:

* guile/ isn't part of SUBDIRS in top-level Makefile.am so it is never
  built...

* building in the directory fails:

Making all in modules
make[1]: Entering directory `/home/jas/src/gnutls/guile/modules'
make[1]: Nothing to be done for `all'.
make[1]: Leaving directory `/home/jas/src/gnutls/guile/modules'
Making all in src
make[1]: Entering directory `/home/jas/src/gnutls/guile/src'
/usr/bin/guile -L ../../modules make-enum-map.scm > enum-map.i.c
ERROR: no code for module (gnutls build enums)
make[1]: *** [enum-map.i.c] Error 1
make[1]: Leaving directory `/home/jas/src/gnutls/guile/src'
make: *** [all-recursive] Error 1
jas at mocca:~/src/gnutls/guile$

* configure.ac contains:

   AC_PATH_PROG([guile_snarf], [guile-snarf], [not-found])
   if test "x$guile_snarf" = "xnot-found"; then
      AC_MSG_ERROR([`guile-snarf' not found.  Please install Guile 1.8.x or later.])
   fi

  This seems unsafe.  Could you change this so that if guile-snarf is
  not available, the guile bindings are disabled rather than aborting
  the build?

* Automake complains:

doc/Makefile.am:131: `%'-style pattern rules are a GNU make extension
doc/Makefile.am:139: `%'-style pattern rules are a GNU make extension

We don't want any GNU make extensions.  Hard-coding the rules for the
two files would be one solution.

* The manual's @node's were heavily changed, which causes problems.  You
  shouldn't need these modifications if you use the latest texinfo.  I
  reverted this stuff.

Thanks,
Simon

Another problem:

./configure: line 7459: GUILE_PROGS: command not found
./configure: line 7460: GUILE_FLAGS: command not found

The m4 files that define these macros need to be included in GnuTLS, I
suggest to place them in m4/.
