Thus, nfs4_init_client() is a good\nspot to perform trunking discovery.\n\nDiscovery requires a client to establish a fresh client ID, so our\nclient will now send SETCLIENTID or EXCHANGE_ID as the first NFS\noperation after a successful ping, rather than waiting for an\napplication to perform an operation that requires NFSv4 state.\n\nThe exact process for detecting trunking is different for NFSv4.0 and\nNFSv4.1, so a minorversion-specific init_client callout method is\nintroduced.\n\nCLID_INUSE recovery is important for the trunking discovery process.\nCLID_INUSE is a sign the server recognizes the client\u0027s nfs_client_id4\nid string, but the client is using the wrong principal this time for\nthe SETCLIENTID operation.

This allowed\nusers to read files that didn\u0027t have READ access but did have EXEC access,\nwhich is obviously wrong.\n\nThis patch adds an ACCESS call to the OPEN compound to handle the\ndifference between OPENs for reading and execution. Since we\u0027re going\nthrough the trouble of calling ACCESS, we check all possible access bits\nand cache the results hopefully avoiding an ACCESS call in the future.\n\nSigned-off-by: Weston Andros Adamson \u003cdros@netapp.com\u003e\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "57a51048da742c764b6ce5d028c7f334ae04d363", "tree": "21a35aa29c1d04b25b7e00bc375e1cc198a01fe8", "parents": [ "6938867edba929a65a167a97581231e76aeb10b4" ], "author": { "name": "Bryan Schumaker", "email": "bjschuma@netapp.com", "time": "Thu Aug 09 14:05:51 2012 -0400" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Mon Oct 01 15:18:44 2012 -0700" }, "message": "NFS: Use kzalloc() instead of kmalloc() in the idmapper\n\nThis will allocate memory that has already been zeroed, allowing us to\nremove the memset later on.\n\nSigned-off-by: Bryan Schumaker \u003cbjchuma@netapp.com\u003e\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "6938867edba929a65a167a97581231e76aeb10b4", "tree": "9f1fcee1c9dc22515d335c69db0f01e5eb9f4bb1", "parents": [ "fcb6d9c6b719b633e9b98d26d8a7937209e8bf21" ], "author": { "name": "Bryan Schumaker", "email": "bjschuma@netapp.com", "time": "Wed Sep 26 15:25:52 2012 -0400" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Mon Oct 01 15:17:25 2012 -0700" }, "message": "NFS: Remove bad delegations during open recovery\n\nI put the client into an open recovery loop by:\n\tClient: Open file\n\t\tread half\n\tServer: Expire client (echo 0 \u003e /sys/kernel/debug/nfsd/forget_clients)\n\tClient: Drop vm cache (echo 3 \u003e /proc/sys/vm/drop_caches)\n\t\tfinish reading file\n\nThis causes a loop because the client never updates the nfs4_state after\ndiscovering that the delegation is invalid.
