https://bugzilla.novell.com/show_bug.cgi?id=863749 https://bugzilla.novell.com/show_bug.cgi?id=863749#c0 Summary: NFSv3 fallback failure when NFSv3 Server is UDP only Classification: openSUSE Product: openSUSE 13.1 Version: Final Platform: i586 OS/Version: openSUSE 13.1 Status: NEW Severity: Major Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: kieltux@gmail.com QAContact: qa-bugs@suse.de Found By: --- Blocker: --- Created an attachment (id=578454) --> (http://bugzilla.novell.com/attachment.cgi?id=578454) Testcase logs NFSv3 TCP/UDP - NFSv3 UDP only User-Agent: Mozilla/5.0 (X11; Linux i686; rv:24.0) Gecko/20100101 Firefox/24.0 Mounting a NFSv3 UDP only export fails. To mount a NFSv3 UDP only export you have to add a mount options (-o udp or -o nfsvers=3). This should be not necessary because of auto-negotiation. Reproducible: Always Steps to Reproduce: 1.Server with NFSv3 UDP only 2.Mount the server NFSv3 export without any options (-o udp or -o nfsvers=3) Actual Results: Mount fails with mount.nfs: mount(2): Connection refused Auto-negotiation is stuck on NFSv4. Expected Results: Mount success. In the attachment is my testcase log for following scenario: Client: openSUSE 13.1 32bit, Kernel 3.11.10-7-default Server_1: NFSv3 UDP only Mounting Server_1: NFSv3 UDP only without mount options (-o udp or -o nfsvers=3) == Fail Mounting Server_1: NFSv3 UDP only with mount options (-o upd or -o nfsvers=3) == Success Server_2: NFSv3 TCP/UDP Mounting Server_2: NFSv3 TCP/UDP without mount options (.o upd or -o nfsvers=3) == Success mount -v logs and /var/log/messages -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Please install the appropriate nfs-client from http://download.opensuse.org/repositories/home:/neilbrown:/branches:/openSUS... You particularly want the "mount.nfs" program in /sbin Please let me know if that fixes the problem. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Tested with client openSUSE 13.1 32bit 3.11.10-7-default and server with NFSv3 UDP only. # mount.nfs -v server_nfs3_udponly:/export /mnt mount.nfs: timeout set for Mon Feb 17 14:24:16 2014 mount.nfs: trying text-based options 'vers=4,addr=192.168.0.100,client mount.nfs: mount(2): Connection refused mount.nfs: trying text-based options 'addr=192.168.0.100' mount.nfs: prog 100003, trying vers=3, prot=6 mount.nfs: portmap query retrying: RPC: Program not registered mount.nfs: prog 100003, trying vers=3, prot=17 mount.nfs: trying 192.168.0.100 prog 100003 vers 3 prot UDP port 2049 mount.nfs: prog 100005, trying vers=3, prot=17 mount.nfs: trying 192.168.0.100 prog 100005 vers 3 prot UDP port 32770 Makes it sense to test with this mount.nfs also openSUSE 12.3 e.g. with 3.7.10-88.1.gabf8346?

The kernel version doesn't make much difference with this bug. I've sent the fix upstream and submitted to Factory. I will hold off submitting an openSUSE update for the moment as we had one recently and there might be more bugs to come... -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
