  "message": "nfsd41: exchange_id operation\n\nImplement the exchange_id operation confoming to\nhttp://tools.ietf.org/html/draft-ietf-nfsv4-minorversion1-28\n\nBased on the client provided name, hash a client id.\nIf a confirmed one is found, compare the op\u0027s creds and\nverifier.  If the creds match and the verifier is different\nthen expire the old client (client re-incarnated), otherwise,\nif both match, assume it\u0027s a replay and ignore it.\n\nIf an unconfirmed client is found, then copy the new creds\nand verifer if need update, otherwise assume replay.\n\nThe client is moved to a confirmed state on create_session.\n\nIn the nfs41 branch set the exchange_id flags to\nEXCHGID4_FLAG_USE_NON_PNFS | EXCHGID4_FLAG_SUPP_MOVED_REFER\n(pNFS is not supported, Referrals are supported,\nMigration is not.).\n\nAddress various scenarios from section 18.35 of the spec:\n\n1. Check for EXCHGID4_FLAG_UPD_CONFIRMED_REC_A and set\n   EXCHGID4_FLAG_CONFIRMED_R as appropriate.\n\n2. Return error codes per 18.35.4 scenarios.\n\n3. Update client records or generate new client ids depending on\n   scenario.\n\nNote: 18.35.4 case 3 probably still needs revisiting.  The handling\nseems not quite right.\n\nSigned-off-by: Benny Halevy \u003cbhalevy@panasas.com\u003e\nSigned-off-by: Andy Adamosn \u003candros@netapp.com\u003e\nSigned-off-by: Benny Halevy \u003cbhalevy@panasas.com\u003e\n[nfsd41: use utsname for major_id (and copy to server_scope)]\n[nfsd41: fix handling of various exchange id scenarios]\nSigned-off-by: Mike Sager \u003csager@netapp.com\u003e\nSigned-off-by: Benny Halevy \u003cbhalevy@panasas.com\u003e\n[nfsd41: reverse use of EXCHGID4_INVAL_FLAG_MASK_A]\n[simplify nfsd4_encode_exchange_id error handling]\n[nfsd41: embed an xdr_netobj in nfsd4_exchange_id]\n[nfsd41: return nfserr_serverfault for spa_how \u003d\u003d SP4_MACH_CRED]\nSigned-off-by: Benny Halevy \u003cbhalevy@panasas.com\u003e\nSigned-off-by: J.
