From: Benny Halevy Date: Fri, 3 Apr 2009 05:28:08 +0000 (+0300) Subject: nfsd41: sequence operation X-Git-Tag: v2.6.30-rc1~183^2~25 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b85d4c01b76f6969a085d07a767fa45225cb14be;p=pandora-kernel.git nfsd41: sequence operation Implement the sequence operation conforming to http://tools.ietf.org/html/draft-ietf-nfsv4-minorversion1-26 Check for stale clientid (as derived from the sessionid). Enforce slotid range and exactly-once semantics using the slotid and seqid. If everything went well renew the client lease and mark the slot INPROGRESS. Add a struct nfsd4_slot pointer to struct nfsd4_compound_state. To be used for sessions DRC replay.
