Subject: [PATCH Version 4 1/5] SUNRPC: don't map EKEYEXPIRED to EACCES in call_refreshresult
Date: Thu, 18 Jul 2013 15:35:26 -0400	[thread overview]
Message-ID: <1374176130-11657-2-git-send-email-andros@netapp.com> (raw)
In-Reply-To: <1374176130-11657-1-git-send-email-andros@netapp.com>

From: Andy Adamson <andros@netapp.com>

The NFS layer needs to know when a key has expired.
This change also returns -EKEYEXPIRED to the application, and the informative
"Key has expired" error message is displayed. The user then knows that
credential renewal is required.
