2.6 upstream patch to address the "garbage, exit EIO" messages
This is a patch destined for upstream integration in 2.6.11, or thereabouts.
It does address the console message issue; still testing to see if it also
handles the filer context idle-expiry issue.
as far as i can tell, this patch also addresses the case where the server expires the session's security context (as described above). the client now retries the failing RPC with a GSS sequence number of zero so that a new context can be established. the patch attached to this ticket, then, is required for supporting NFSv3 and NFSv4 with Kerberos. kernel 2.6.10-1.741_FC3 still has this issue. this patch will appear in 2.6.11, so any FC3 kernel based on 2.6.11 or higher will have this already. however, it will be necessary to add this patch to RHEL 4.0's kernel in order to support NFS (any version) over Kerberos. An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on the solution and/or where to find the updated files, please follow the link below. You may reopen this bug report if the solution does not work for you. http://rhn.redhat.com/errata/RHSA-2005-420.html |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041111 Firefox/1.0 Description of problem: Mounted a NetApp filer with "vers=3,sec=krb5" mount options. The mount is the user home directory. The message "RPC: garbage, exit EIO" appears in the console log each time a user logs in. Version-Release number of selected component (if applicable): 2.6.9-1.681_FC3 How reproducible: Always Steps to Reproduce: 1. Set up your system to use Kerberos 5 2. Mount a NetApp filer with "vers=3,sec=krb5" as the home directory 3. log in Actual Results: "RPC: garbage, exit EIO" appears in console log. Sometimes a user's home directory becomes inaccessible (we theorize that the filer is idle-expiring their Kerberos context). Expected Results: No error messages in the console log. Linux NFS client should recover after filer times out GSS context allowing user to continue accessing their files after a period of inactivity. Additional info:
