From: stig Date: Mon, 27 Jan 2014 09:02:06 +0000 (+0000) Subject: Added back x509af_get_last_algorithm_id() removed in revision 54647 to X-Git-Url: http://git.samba.org/?p=metze%2Fwireshark%2Fwip.git;a=commitdiff_plain;h=4ce725c408b349d0bb745d330abf41bf8adcf2e9 Added back x509af_get_last_algorithm_id() removed in revision 54647 to restore usage in cms and pkcs12. They never got a valid value in actx->external.direct_reference because they use another actx in this case. This will add back the global variable in x509af, but this is needed until we manage to pass the value in another way. See comments in bug 9573. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@54975 f5534014-38df-0310-8fa8-9805f1628bb7 --- diff --git a/asn1/cms/cms.cnf b/asn1/cms/cms.cnf index af843d1703..b2c81b09f4 100644 --- a/asn1/cms/cms.cnf +++ b/asn1/cms/cms.cnf @@ -153,8 +153,8 @@ RevocationInfoChoice/other otherRIC old_offset = get_ber_identifier(tvb, old_offset, NULL, NULL, NULL);
