https://bugzilla.novell.com/show_bug.cgi?id=357528 Summary: Possible NFS integer overflow with openSUSE-10.3 Product: openSUSE 10.3 Version: Final Platform: x86-64 OS/Version: openSUSE 10.3 Status: NEW Severity: Critical Priority: P5 - None Component: Network AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: ffiene@veka.com QAContact: qa@suse.de Found By: Customer I think this is an integer overflow, because: If i do a "ls -l backup.iso" on my server share mounted via nfs: -rw-r--r-- 1 ffiene users 3711641600 10. Jul 2007 backup.iso If i do the same on the same share mounted with cifs: -rw-r--r-- 1 ffiene users 8006608896 10. Jul 2007 backup.iso The last file size is 2^32 + first file size! I've copied this file from my old server (SUSE-10.0-64bit) to the new one (10.3-64bit) via nfs and for gods sake, this was done correctly! So this didn't appear on 10.0's nfs! Problem is server based, with 10.3 client and 10.0 server everything was working fine! Who could fix this? -- 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.

So Server is running v2, strange. So default mode is v2? I've only edited the /etc/exports as usual.

What distro is running on the server? Maybe you have the wrong NFS server install somehow. -- 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.
