Date: Fri, 25 Oct 2013 00:33:53 +0200 From: Frank Dittrich <frank_dittrich@...mail.com> To: john-dev@...ts.openwall.com Subject: commit 47a2724 removed NSS and NSPR runtime version checks from --list=build-info ... to avoid conflicts in case the runtime version is too old. I suggest re-adding that information, at least for DEBUG builds. According to https://bugzilla.mozilla.org/show_bug.cgi?id=673115 the functionality to report the NSS runtime version has been added on 2011-08-01 00:08:40 PDT for 3.13. On my Fedora 18 system (Fedora 18 most likely reaches end of life in december) I have NSS library version 3.15.2. On August, 19th, when I built john on bull, bull had NSS library version: 188.8.131.52 NSPR library version: 4.9.5 Since https://bugzilla.mozilla.org/show_bug.cgi?id=673381 the runtime version is available at the end of the about:support info in firefox (added upstream on 2012-03-13 05:42:37 PDT): On my Fedora 18 system, about:support shows these library versions (at the end of the page, after tons of other more or less useful stuff): Library Versions Expected minimum version Version in use NSPR 4.10 4.10.1 NSS 3.15.1 3.15.2 Extended ECC NSSSMIME 3.15.1 3.15.2 Extended ECC NSSSSL 3.15.1 3.15.2 Extended ECC NSSUTIL 3.15.1 3.15.2 So, firefox 24.0 requires at least NSS library version 3.15.1. Are there really any systems around where NSS library version is smaller than 3.13? Since magnum removed that functionality, may be he had a system with an older runtime version? Can we at least re-add the runtime library version withing #ifdef DEBUG ... #endif? The same applies to the runtime info of the NSPR library version that has been implemented with version 4.8.9, had been added to --list=build-info with commit 03234df. I'd also like to see that information. May be just use #ifdef DEBUG ... #endif as well. Then, there is a way to get this information. (If the DEBUG version causes a run time error, that's useful information as well.) And it is easier to permanently add this information even without #ifdef DEBUG, once we are sure nobody is using libraries that old anymore. When I first committed the --list=build-info change to report the NSS and NSPR library version (commit 81ef017, Sun Dec 30 19:35:13 2012 +0100; that was still on john.c instead of listconf.c), I had a system with NSS library version: 184.108.40.206 (loaded: 220.127.116.11 Extended ECC) NSPR library version: 4.9.2 (Apparently, I used the available NSS library update to test the reporting of a different runtime version of the NSS library. Probably NSPR had been updated as well. But I don't know what the NSPR run time version was at that time. I would need to dig through my old backups to find out which Fedora version and which NSPR library version I used at that time. But I don't think I want to spend time on that. Fedora 18 had been released on 2013-01-15, so it was either Fedora 16 or Fedora 17.) Frank
