This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '23'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 23 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. |
Created attachment 1212102 [details] fedora 23, one ip, two lock owners Description of problem: By using commercial NFS program I was able to send NLM lock requests on behalf of different lock owners from the same client host. I found inconsistent behavior of Fedora NLM Server with NetApp NLM Server. // attached pcap file "fedora23_One_IP_Two_LockOwners.pcap" represent scenario with Fedora 23 NLM Server 37 0.019313 192.168.22.110 192.168.9.100 NLM 246 V4 LOCK Call (FH:0x07aa2ec4 Owner:LuisAlberto) 40 0.101989 192.168.9.100 192.168.22.110 NLM 94 V4 LOCK Reply 41 0.102140 192.168.22.110 192.168.9.100 NLM 246 V4 LOCK Call (FH:0x07aa2ec4 Owner:LuisAlberto2) 44 0.102648 192.168.9.100 192.168.22.110 NLM 94 V4 LOCK Reply attached pcap file "netapp_One_IP_Two_LockOwners.pcap" represent scenario with NetApp NLM Server 46 1.051257 172.16.93.110 172.16.1.181 NLM 254 V4 LOCK Call (FH:0x5a66b259 Owner:LuisAlberto) 47 1.051984 172.16.1.181 172.16.93.110 NLM 94 V4 LOCK Reply 48 1.051999 172.16.93.110 172.16.1.181 NLM 254 V4 LOCK Call (FH:0x5a66b259 Owner:LuisAlberto2) 49 1.052627 172.16.1.181 172.16.93.110 NLM 94 V4 LOCK Reply NLM_BLOCKED Second lock was granted by Fedora 23 NLM Server, but blocked by NetApp. I think the behavior of NetApp server more suitable. RHEL6.5 behaves like Fedora 23. Version-Release number of selected component (if applicable): Fedora 23, RHEL6.5 How reproducible: I used commercial software from virtualinstruments, which allow to run several lock owners on one client host Steps to Reproduce: 1. 2. 3. Actual results: Second lock was granted Expected results: Second lock should be blocked Additional info:
