tmcpeaknkinder, bknudson: if you get a chance could you have a look at https://review.openstack.org/16304115:18
nkindertmcpeak: I have it up and have been reviewing it15:19
bknudsonis getting sick of these SSL attacks.15:19
tmcpeaklol15:19
tmcpeaknkinder: cool, sounds good, thanks nkinder15:19
bknudsonstop using it since it doesn't do anything anyways.15:19
bknudsonluckily we don't use java.15:19
tmcpeakI think what we have is a behavior problem, not a tech problem.  If we could all just agree not to MITM eachother's traffic the world would be a much better place15:20

bknudsontmcpeak: do the configurations in http://docs.openstack.org/security-guide/content/tls-proxies-and-http-services.html disable export ciphers?15:25
bknudsonSSLCipherSuite HIGH:!RC4:!MD5:!aNULL:!eNULL:!EXP:!LOW:!MEDIUM has !EXP15:25
tmcpeakyeah, I assume that's what this line does15:25
tmcpeakyep, that's the one I was going to paste :)15:25
tmcpeak!EXP15:26
tmcpeakDisallows export encryption algorithms, which by design tend to be weak, typically using 40 and 56 bit keys.15:26
tmcpeakUS Export restrictions on cryptography systems have been lifted and no longer need to be supported.15:26
openstacktmcpeak: Error: "EXP" is not a valid command.15:26
bknudsonjust make it the default for crying out loud.15:26
bknudsonno wonder everyone messes this up.15:26
bknudsontmcpeak: read through https://review.openstack.org/#/c/163041/ and looks good to me.15:28
tmcpeaklol, yeah.  Insecure defaults suck15:28

bknudsonsicarie: nkinder was working on some docs for policy.json15:56
bknudsonI was also working on some docs for keystone.15:57

tmcpeakcool, so nkinder, hyakuhei, bdpayne: could use final thumbs up here: https://review.openstack.org/16304116:27
* bdpayne looks16:27
*** dwyde has quit IRC16:28
bdpaynetmcpeak lgtm16:33
tmcpeakbdpayne: thanks!16:33
hyakuheiThe only concern I have is the services section16:34
hyakuheiThey layout is very different to how we normally do it16:34
tmcpeakcopied that from bdpayne's poodle note16:34
hyakuheiand if we ever get around to pushing these all through some parser it’ll break16:34
hyakuheinkinder: not around?16:34
bdpaynelayout?16:34
hyakuheiIt’s kind of ok if it breaks the parser because it can be manually fixed up if we only have that issue with one or two notes and at least this is nice and readable.16:35
bdpaynepretty sure the Poodle note started with the official template16:35
bdpayneso if there's an issue, perhaps the template needs fixing?16:35
hyakuheiNo, if that’s how the poodle note does it it’s technically wrong too16:35
nkinderhyakuhei: I'm around, but in a meeting16:36
hyakuheiServices are normally just comma separated https://wiki.openstack.org/wiki/OSSN/OSSN-004216:36
tmcpeakhyakuhei is talking about the list of services and versions16:36
tmcpeakalthough that isn't really applicable to general TLS problems16:36
hyakuheiYeah, just the Affected Services / Software section16:36
hyakuheitmcpeak: that’s true16:36
hyakuheiHowever, you probably want each of the openstack services listed in there and move the (very good) list of TLS stuff into some other section16:37
bdpaynenot sure I agree with that, tbh16:37
tmcpeakhyakuhei: so every version and every service?16:37
bdpayneit will make the note harder to parse16:37
tmcpeakwhat about other components which might be using TLS16:37
hyakuheiThat way if we ever have some tool that allows you to, for example, view all OSSNs that potentially affect Keystone it’ll come up in the search16:37
bdpayneparse... by humans in this case16:37
hyakuheibdpayne: That’s the standard, we can talk about changing the standard but that’s an entirely separate conversation16:38
hyakuheione I want nkinder to be around for.16:38
tmcpeakwell, in this case I just chose to match what we already had for POODLE.  IMO listing all services and versions will be horrible to look at, but yeah, makes it machine parseable. We really aren't using that currently though, so we'd need to do work in any case16:40
hyakuheiSo I’m ok with it going through but it will break the tooling we want to put around OSSNs later.16:42
tmcpeakyeah, agree16:42
hyakuheiIncidentally I think this is a very good OSSN, my comments are only a reflection on the standard schema we currently use16:42
tmcpeakhyakuhei: thank you16:42
hyakuheiand that we should adhere to in most cases until we fix the schema…16:43

nkindertmcpeak: ok, out of my meeting...16:55
nkindertmcpeak: so the list of affected services is a bit odd, but these generic crypto vulnerability notes don't really fit the mold of real bugs/issues in OpenStack itself16:56
nkinderI don't want to list every possible service, and this affects more than OpenStack services (messaging brokers, SSL terminators, etc.)16:57
*** singlethink has joined #openstack-security16:57
tmcpeaknkinder: yeah, I agree16:57
sicarienkinder: I think one of my comments led to this - I was trying to get a concrete method for determining exposure there16:58
tmcpeakhyakuhei agrees also16:58
tmcpeakit doesn't fit our traditional method of listing services and versions16:59
nkinderwell, I would love to have an automatic parsing tool16:59
nkinder...but we don't have one here today16:59
tmcpeakso a smart parser could recognize when something doesn't parse and leave a smart comment instead16:59
nkinderI think if we wanted a real format that could be parsed, it wouldn't be what we have today17:00

nkindertmcpeak: fyi - your line-wrap width was too wide for the OSSN17:43
nkindertmcpeak: not a big deal (I'll reformat for the e-mail)17:43
tmcpeaknkinder: crap, was it? thought I had it set for 8017:43
nkindertmcpeak: just an FYI that the width is shorter than what we use for PEP817:43
nkindertmcpeak: it's 7217:44
tmcpeakahhhh17:45
tmcpeakforgot all about that :)17:45
nkindertmcpeak: I'm fixing it17:45

tmcpeakI gave my +1 fwiw17:57
tmcpeak:)17:57
nkindertmcpeak: you're fast17:57
nkinderbdpayne: ^^ Given it's just white-space, I'm thinking we should just +A it without the standard "2 core" rule.17:58

* bdpayne will approve anything ;-)17:58
nkinderbdpayne: thanks!18:00
nkindertmcpeak: I'll publish as soon as I see the merge come through18:00
tmcpeakI need to start gaming my "positive response on reviews" in stackalytics18:01
tmcpeakI have like 25% positive18:01
tmcpeaknkinder: awesome, thank you18:01
tmcpeakI'll throw up the wiki page18:01
nkindertmcpeak: that's good actually18:01
nkinderif you had 90% positive, there's likely a problem with not being thorough enough :)18:01
