Re: [ceph-users] Kernel rbd cephx signatures

Hi, I found two maybe related bugs in the tracker (#4287, #3657) but both are resolved, so I'm wondering if there's spmething I'm doing wrong. Has anybody sucessfully mapped rbd images with kernel rbd, when cephx require signatures is set to true in the cluster? Thanks for your help, best

Hi Kurt, Your original analysis is correct: cephx signatures aren't yet implemented in the kernel client. I don't have a good indication of when this will be prioritized, unfortunately. I'm not aware of anybody who has targetted this or has even made note of the potential vulnerability. It

Hi Sage, thanks for your answer. Am I right, that the communication between nodes that support cephx signatures is still signed, although the option is set to false? So only the communication between the client, mapping the rbd, and the relevant OSDs and MONs is not signed? Thanks, best regards,

Correct. During the intiial handshake, the to ends will decide whether to use signatures based on whether it is supported by both ends. That option allows them to continue even if it is not. You probably want the more specific options: cephx_require_signatures = false

Hi, I have to open our CEPH cluster for some clients, that only support kernel rbd. In general that's no problem and works just fine (verified in our test-cluster ;-) ). I then tried to map images from our production cluster and failed: rbd: add failed: (95) Operation not supported After some
