Subject: SUNRPC: don't map EKEYEXPIRED to EACCES in call_refreshresult
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5bad04d7bc7fe12a89b716f8b63d32b5735f6dd2;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

SUNRPC: don't map EKEYEXPIRED to EACCES in call_refreshresult

commit f1ff0c27fd9987c59d707cd1a6b6c1fc3ae0a250 upstream.

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.
