Subject: SUNRPC: don't map EKEYEXPIRED to EACCES in call_refreshresult
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f1ff0c27fd9987c59d707cd1a6b6c1fc3ae0a250;p=linux-beck.git

SUNRPC: don't map EKEYEXPIRED to EACCES in call_refreshresult

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.
