Comment 1 Corey Halpin 2016-06-08 12:02:34 UTC
The warning you report is both expected and harmless. It does not cause the error, which is:

socket.o: In function `SSLOpen':
socket.c:(.text+0x128a): undefined reference to `SSLv3_client_method'

This is the same error that was fixed with the update to fetchmail in fetchmail-6.3.26_3:

Is your ports tree up to date? Or, by chance, are you following the quarterly branch?

Comment 5 VK freebsd_triage 2016-06-10 18:26:03 UTC
This is being caused by missing SSLv3 in OpenSSL. Have you built OpenSSL from ports with "SSLv3" disabled?

There are patches to make fetchmail build with no SSLv3 support from LibreSSL or OpenSSL, which should be applied to fetchmail since SSLv3 should not be used any more:


CC'ing Bernard. Looks to me the patch will have to be reworked to fit code changes that occurred in the meanwhile.

It looks like the upstream fixed it, but I see no official release after it:

Comment 6 Corey Halpin 2016-06-10 19:46:07 UTC

I would not that there is already a patch, included in fetchmail 6.3.26_3 with commit https://svnweb.freebsd.org/ports?view=revision&revision=415811 that disables SSLv3.  Does this not address the issue you're raising?

You are indeed correct that fetchmail 6.3.26 is the most recent stable release.

The initial build log attached to this bug was for fetchmail 6.3.26_2, rather than the current version 6.3.26_3.  The next two attachments are for 6.3.26_3, but I'm wondering if 'make clean' was not run in between the two?  In any case, I'm not able to reproduce this failure with 'poudriere testport' on 10.3/amd64.
Comment 7 Corey Halpin 2016-06-10 19:52:24 UTC
(In reply to Corey Halpin from comment #6)

Ugh... apologies. I was confusing SSLv2 with SSLv3.  I'll see if I can replicate by disabling SSLv3 in openssl from ports, and if so will look at integrating the patch you reference.

(In reply to Corey Halpin from comment #7)
> I'll see if I can replicate by disabling SSLv3 in openssl from ports

Yup, you will. I also confirm I did the same with all the combinations (OpenSSL with v3, without v3, LibreSSL (unconditional without)) and it failed at exactly the same spot as reported here, when *SSL was without v3. Don't have poudriere logs at the moment, but if required I'll re-run the tests.
Comment 9 Bernard Spil freebsd_committer 2016-06-10 21:03:18 UTC
I've just built fetchmail here without problems (my base libcrypto and libssl are LibreSSL 2.4.1)

The problem you're running into is that you're running into is with GSSAPI. You cannot combine Open/LibreSSL from ports with GSSAPI from base. Set 


to solve this. Please report back if that fixes your issues.

Changes for bsd.openssl.mk and Uses/gssapi.mk are in review
Comment 10 Helmut Ritter 2016-06-11 11:50:47 UTC
I can't use libressl-devel because openntpd wants libressl:

Comment 11 Bernard Spil freebsd_committer 2016-06-11 13:09:09 UTC
The same should work with regular security/libressl.

If you need to, open a separate bug for the conflict when building OpenNTPd please.

Proposed patch

In my testing, OPTIONS_SET+= GSSAPI_HEIMDAL was not sufficient to resolve the issue.  This was for two reasons.  First, the fetchmail port wasn't ever updated to use USES=gssapi.  Second, there was a reference in fetchmail's own socket.c to SSLv3_client_method().

In the attached patch, I've remedied the first issue and integrated the relevant part of the patch Vladimir referenced, which removes the reference in socket.c.

With this patch applied, portlint has no complaints and fetchmail passes 'poudriere testport' on 9.3, 10.1, and 10.3 (all amd64) using base OpenSSL, ports OpenSSL, ports OpenSSL with SSL v2 and v3 disabled, and LibreSSL.

For the builds involving ports, the following was used in make.conf to avoid the issue Bernard points out with mixing GSSAPI from ports and base:

I used GSSAPI_MIT because I encountered a build failure with security/heimdal when using LibreSSL (reported as 210392).
Comment 13 Bernard Spil freebsd_committer 2016-06-19 20:41:57 UTC
That looks pretty solid! Thanks!

I'd however change this slightly wrt the SSLv2/SSLv3 detection. Doesn't require any configure.ac patch.

+#ifndef OPENSSL_NO_SSL2


These are defined with the regular openssl/libressl includes.
e.g. from /usr/local/include/openssl/opensslfeatures.h
# define OPENSSL_NO_SSL2
# define OPENSSL_NO_SSL3

These are consistent between OpenSSL and LibreSSL

Proposed patch v2

revise based on feedback; portlint is still happy, as are the set of 'poudriere testport' runs mentioned for v1 of the patch.

You may want to swap ifdef for ifndef for this to work as you'd expect :x

Proposed patch v3

What I was aiming for with the #ifdefs in fetchmail.c was to mimic what upstream did in this commit: 

If I'm understanding it correctly, it will display +SSL in the version string when SSL with all its variants is supported +SSL-SSLv2 when SSL is supported except v2, and +SSL-SSLv2-SSLv3 when SSL is supported without v2 or v3.

Which is all well and good, except that none of it works without including ssl.h. I've added that in the attached.

svn diff for mail/fetchmail

Hi Corey,

Please review this patch. This contains your changes to build without SSLv3.

Additionally this aligns the port with the current ports framework

  - Remove pkg-install pkg-deinstall
  - Use pkg-plist keywords for ownership/mode
  - Options-ify more

Let me know if this is OK to commit
