Write delegation stateid permission checks

Hi,

I have a question regarding NFS4.1 write delegation stateid permission checks.

Is there a difference in how a server should check permissions for a
write delegation stateid that was given when the file was opened with:
1. OPEN4_SHARE_ACCESS_BOTH
2. OPEN4_SHARE_ACCESS_WRITE

Should the server check permissions for read access as well when
OPEN4_SHARE_ACCESS_WRITE is requested and DELEGATION_WRITE is granted
? or there is an assumption that the client will query the server for
read access permissions ?


Thanks,
Shaul
