jgriffithI'm not convinced that this https://bugs.launchpad.net/cinder/+bug/147542215:01
openstackLaunchpad bug 1475422 in Cinder "Non-admin users can get volumes in non-authorized tenants" [High,In progress] - Assigned to Liyingjun (liyingjun)15:01
jgriffithshould be enforced via db instead of policy15:01
jgriffithIf that's the case why have a policy file if you're just going to hard code things in the DB?15:02
guitarzanjgriffith: not hardcoding anything15:02
guitarzanI'm just very surprised that the project_id filter isn't being applied15:02
guitarzanmaybe we're always using context.elevated?15:02
guitarzanI'm looking into this15:02
jgriffithguitarzan: Ok, just want to make sure I'm following here and we're not basically disabling the policy file15:03
guitarzanno, there is still a policy check15:03
guitarzanbut I'm starting to understand the "" policy15:03
guitarzanor at least where the idea came from15:03
jgriffithguitarzan: I'll just note the point in the bug and move on :)15:03
openstackgerritVincent Hou proposed openstack/cinder: Add the notification and the migration progress indication  https://review.openstack.org/20395215:03
guitarzan(whether it's correct or not, I'm not sure)15:03
jgriffithLOL15:03
guitarzanfor example the get_all policy15:04
guitarzanshould be ""15:04
guitarzanbecause anyone should be able to get their volume list15:04
guitarzananyone should be able to get "a" volume15:04
guitarzannot a specific one15:04
guitarzanthis viewable_admin_meta thing in the get call completely changes how it works15:05
guitarzanit's no longer "see if the user owns the volume" because it's an admin context15:05
guitarzanso now that path is relying on policy, instead of the owner of the object15:05
jungleboyjjgriffith: Pong.15:05
jgriffithguitarzan: that admin_meta and all that is frankly one of the not so good things we did15:05
jgriffithjungleboyj: NM, talked with guitarzan15:05
guitarzanjgriffith: yeah, two paths, one being elevated, one being not elevated, seems very bad15:06
guitarzanit should probably elevate afterwards to fetch the admin meta15:06
jgriffithguitarzan: it's kinda weird, and ill defined15:06
guitarzaninstead of using an elevated context to get the volume record15:06
jgriffithguitarzan: yeah, I've been pretty sloppy on that stuff in reviews :(15:06
guitarzanI'm a little scared by this admin volume get15:07
jungleboyjjgriffith: Saw that, just followed the discussion.  I agree that the policy is probably the right way to go, but wanted to make the bug so we at least look at guitarzan s concern a bit more.15:08
guitarzanI'm checking to make sure that icehouse behaves like I thought it does15:09
jgriffithjungleboyj: indeed... I think guitarzan 's point (which i better understand now) is that the DB layer enforces the policy checks15:09
guitarzanjgriffith: no, not the policy checks!15:09
guitarzanjust to see if the project_id matches15:09
jgriffithguitarzan: ha... well there ya go15:09
guitarzanno policy15:09
guitarzanignore policy!15:09
* jgriffith doesn't know jack15:09
guitarzanmy tenant id of 115:09
guitarzanvolume get volume with tenant id 215:09
guitarzanshould return a 40415:09
guitarzanregardless of policy15:09
guitarzanthe db should say, nope, couldn't find your volume sir!15:10
jgriffithguitarzan: well, that all goes out the window with public-volumes15:10
guitarzanjgriffith: no argument15:10
eharneyi'm inclined to agree, because if we return 403, we're saying "yes, this volume you aren't supposed to know about does exist with that id"15:10
guitarzanpublic volumes fail with this new policy check as well15:10
*** daemontool_ is now known as marzif_15:10
guitarzaneharney: there's an explicit 403, return a 404 check in the code15:10
guitarzanwhich is a little goofy15:10
*** sgotliv has quit IRC15:10
guitarzanbut it's because we're doing the volume_get call with an elevated context15:11
jgriffitheharney: guitarzan so that makes sense; but my point was then it shouldn't be in the policy file... and it makes me wonder "why policy file"15:11
guitarzanwhcih is the part that i think is actually very wrong15:11
*** diogogmt has joined #openstack-cinder15:11
guitarzanjgriffith: there isn't much point to policy on volume.get()15:11
guitarzanhowever, we have users that simply can't make cinder calls15:11
jgriffithguitarzan: and yes, I agree completely the elevated is the problem, it relied on filtering at API IIRC15:11
guitarzanand that's a case where poilcy works15:11
guitarzanwe have global auth, so all users can actually make any call, but they're not given a role that lets them talk to cinder15:12
*** jasondotstar has quit IRC15:12
guitarzanso our policy says, hey, you have to be a cinder user15:12
*** dannywilson has joined #openstack-cinder15:12

jgriffithI clearly don't have a great perspective on the security and policy related stuff in this case15:13
openstackgerritxing-yang proposed openstack/cinder: Add multiple pools support to VMAX driver  https://review.openstack.org/18999015:14
jungleboyjIn the interest of transparency, I think that the policy Check is sufficient.15:14
jgriffithguitarzan: so just to make sure I understand what you're asking for:15:14
jungleboyjThis is also my first foray into the policy code.15:15
jgriffithguitarzan: You would like it to behave such that NO MATTER WHAT, Tenant-B can NOT do a "get" on Tenant-A's volume?15:15
jgriffithguitarzan: No policy setting, etc.  And to eharney 's point, do the context check and just say "not found"15:15

*** dgrauet has quit IRC15:17

openstackgerritThang Pham proposed openstack/cinder: Continue conversion to volume object  https://review.openstack.org/20140415:19
guitarzanah, icehouse has the same vviewable_admin_meta thing15:19
*** s0nea has quit IRC15:19
guitarzanbasically whenever that got added, policy was used for determining if someone can see a volume and not the project_id of the object15:20
jgriffithguitarzan: Yeah, I think that's "ok", like I said I'm not as invested in this topic as some are.  I do have some concerns about "some" calls being controlled by policy and others ignoring it etc15:20
jgriffithguitarzan: because I'm willing to be a dollar that as soon as we change it like you describe somebody files a bug :)15:20
guitarzanit's not ignoring it15:20
guitarzanjgriffith: haha, that's possible :)15:20
*** piyanai has joined #openstack-cinder15:21
jgriffithguitarzan: Ok.. "not ignoring it" so now I'm clearly confused; because you clearly reinforced my statement that "regardless of anything, Tenant's can't fetch other Tenant's volume"15:21
guitarzanI think policy should be used for "can I make a call"15:21
jgriffithguitarzan: AHHHHH15:22
jgriffithWait15:22
jgriffithThe light just went on15:22
jgriffithI get it15:22
jgriffithguitarzan: You're 1000000% correct!15:22
guitarzanI think the admin_or_owner thing does muddy the water quite a bit15:22
guitarzanthat a lot of percents dude. I'm sure that's not true15:22
*** s0nea has joined #openstack-cinder15:23
guitarzanhowever, this bug does go back to icehouse at least, so it is a big enough deal15:23
jgriffithguitarzan: yep, we're actually on the same page now... and I agree with you and eharney completely15:26
*** sdague has quit IRC15:26
jgriffithguitarzan: and I think I see how to fix it without too much trouble.  The admin meta makes it kinda ugly... because my proposal would make a second call to get that info and filter based on the two lists15:26
guitarzanjgriffith: yeah, I thought that was the case15:27
guitarzanhave to make the metadata call separately with an elevated context15:27
jgriffithguitarzan: I think there's a better way to do that though maybe15:27
jgriffithguitarzan: so it "used" to do that and I changed it15:27
guitarzanwell, you could pass the originating project_id down all the way through the db layers15:28
jgriffithguitarzan: well, in the list call at least15:28
jgriffithguitarzan: because volume-list was taking over 30 seconds to complete with many volumes15:28
guitarzansure15:28
guitarzanI do remember that :)15:28
*** marzif_ has quit IRC15:28
guitarzanit hit me very hard :)15:28
jgriffithguitarzan: because the code would 'get all' then loop through and do the elevated get-admin-meta on each volume15:28
jgriffithhehe15:28
jgriffithyeah.. ok, you remember15:28
guitarzanyeah, it needs to be 2 calls instead of n+1 calls15:29
jgriffithso...15:29
jgriffithyep15:29
jgriffithand that's doable15:29
guitarzanagreed15:29
