( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/1223094?usp=email ) Change subject: Fix RD5a pynfs nfs4.0 failure by handling very large READ offsets ...................................................................... Fix RD5a pynfs nfs4.0 failure by handling very large READ offsets pynfs4.0 test RD5a (testVeryLargeOffset) expected NFS4_OK with 0 bytes and eof=TRUE when a READ is issued beyond the max file offset, but Ganesha was returning NFS4ERR_FBIG. As Per RFC 7530: - If offset ≥ file size, server must return NFS4_OK with zero-length data and eof=TRUE. - NFS4ERR_FBIG is not a valid error for READ. This patch updates nfs4_op_read() to: - Return NFS4_OK with 0 bytes and eof=TRUE if offset ≥ MaxOffsetRead. - Clamp size when (offset + size) would exceed MaxOffsetRead. - Stop using NFS4ERR_FBIG for READ requests.
