poudriere testport log of librelp-1.2.17

If port option OPENSSL is set, loading librelp at runtime fails:

Installed packages to be UPGRADED:
	rsyslog: 8.36.0 -> 8.37.0
	p11-kit: 0.23.12 -> 0.23.13

	libnghttp2: 1.32.0 -> 1.32.1
	gnutls: 3.5.18 -> 3.5.19

Comment 1 Matthew Seaman freebsd_committer 2018-08-26 15:51:48 UTC
What are the options settings you're using for rsyslog8 please?

Initial assesment: it looks like I need to add an openssl option in rsyslog8 to match the one in librelp, and that you will have to choose matching settings for openssl or gnutls in both rsyslog and librelp.  

It's annoying this doesn't trigger any errors until it fails at run-time.

patches to devel/librelp and sysutils/rsyslog8

This should fix linkage of librelp and rsyslog8 when the OPENSSL option is selected in either port.
Comment 3 Matthew Seaman freebsd_committer 2018-08-26 18:38:20 UTC
Hi,

Can you try the patches I just uploaded, and let me know how you get on please?  The patches add a new radio-button option to rsyslog8 which lets you choose one out of:

   GnuTLS
   OpenSSL
   No ssl support

in rsyslog8.  I haven't confirmed this yet, but if you're enabling RELP support in rsyslog8 I suspect you'll either need to use the same TLS library as for librelp, or turn off both TLS libraries in rsyslog8.  Please let me know how you get on.

Matthew

New revision: 478186
URL: https://svnweb.freebsd.org/changeset/ports/478186

Log:
  Fix linkage against libcrypto.so when the OPENSSL option is selected.
  Previously this compiling successfully but resulting in run-time
  failures in applications (rsyslog essentially) that consumed librelp.

Author: matthew
Date: Tue Aug 28 06:49:05 UTC 2018
New revision: 478287
URL: https://svnweb.freebsd.org/changeset/ports/478287

Log:
  Add a new OPENSSL option as an alternative to GNUTLS.  This parallels
  a simlar fix to librelp, and tracks the upstream project's intention
  to switch from gnutls to openssl over time.  The default remains to
  not compile in any TLS support in rsyslog8.

Still does not work as expected:

New packages to be INSTALLED:
	rsyslog: 8.37.0_1 [lrau-repo]
	librelp: 1.2.17_1 [lrau-repo]
rsyslogd: could not load module '/usr/local/lib/rsyslog/omrelp.so', dlopen: /usr/local/lib/librelp.so.0: Undefined symbol "SSL_set_ex_data"  [v8.37.0 try http://www.rsyslog.com/e/2066 ]

Interesting side effect:

Question: Does your option combination trigger a bug in dialog4ports-0.1.6 ?

New revision: 478763

Log:
  Second try at fixing the linking problems with librelp when the
  OPENSSL option is selected.  The undefined symbol 'SSL_set_ex_data'
  from the original PR clearly comes from libssl.so.

Works now as expected.
Thanks for the fix!
