From 496c262cf01106a546ffb7df6fea84b8b881ee19 Mon Sep 17 00:00:00 2001 From: Andy Adamson Date: Fri, 3 Apr 2009 08:28:48 +0300 Subject: [PATCH] nfsd41: check encode size for sessions maxresponse cached Calculate the space the compound response has taken after encoding the current operation. pad: add on 8 bytes for the next operation's op_code and status so that there is room to cache a failure on the next operation. Compare this length to the session se_fmaxresp_cached and return nfserr_rep_too_big_to_cache if the length is too large. Our se_fmaxresp_cached will always be a multiple of PAGE_SIZE, and so will be at least a page and will therefore hold the xdr_buf head.
