root of NFS filesystem\n\n\n\nTo obey NFS cache semantics, the client must verify the cached\nattributes when a file is opened. In most cases this is done by a call to\nd_validate as one of the last steps in path_walk.\n\nHowever for the root of a filesystem, d_validate is only ever called\non the mounted-on filesystem (except when the path ends \u0027.\u0027 or \u0027..\u0027).\nSo NFS has no chance to validate the attributes.\n\nSo, in nfs_opendir, we revalidate the attributes if the opened\ndirectory is the mountpoint. This may cause double-validation for \".\"\nand \"..\" lookups, but that is better than missing regular /path/name\nlookups completely.\n\nSigned-off-by: NeilBrown \u003cneilb@suse.de\u003e\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "5df6b8e65ad0f2eaee202ff002ac00d1ac605315", "tree": "2eff6606f8e39dc1fd7eb8a05feb2a9927151805", "parents": [ "fe21ea18c742ab0eb8f6f8ebc543374839a02a87", "3dce9a5c3a39a664e372886ea86c42ae7ae33dfc" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Aug 07 13:19:36 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Aug 07 13:19:36 2010 -0700" }, "message": "Merge branch \u0027nfs-for-2.6.36\u0027 of git://git.linux-nfs.org/projects/trondmy/nfs-2.6\n\n* \u0027nfs-for-2.6.36\u0027 of git://git.linux-nfs.org/projects/trondmy/nfs-2.6: (42 commits)\n NFS: NFSv4.1 is no longer a \"developer only\" feature\n NFS: NFS_V4 is no longer an EXPERIMENTAL feature\n NFS: Fix /proc/mount for legacy binary interface\n NFS: Fix the locking in nfs4_callback_getattr\n SUNRPC: Defer deleting the security context until gss_do_free_ctx()\n SUNRPC: prevent task_cleanup running on freed xprt\n SUNRPC: Reduce asynchronous RPC task stack usage\n SUNRPC: Move the bound cred to struct rpc_rqst\n SUNRPC: Clean up of rpc_bindcred()\n SUNRPC: Move remaining RPC client related task initialisation into clnt.c\n SUNRPC: Ensure that rpc_exit() always wakes up a sleeping task\n SUNRPC: Make the credential cache hashtable size configurable\n SUNRPC: Store the hashtable size in struct rpc_cred_cache\n NFS: Ensure the AUTH_UNIX credcache is allocated dynamically\n NFS: Fix the NFS users of rpc_restart_call()\n SUNRPC: The function rpc_restart_call() should return success/failure\n NFSv4: Get rid of the bogus RPC_ASSASSINATED(task) checks\n NFSv4: Clean up the process of renewing the NFSv4 lease\n NFSv4.1: Handle NFS4ERR_DELAY on SEQUENCE correctly\n NFS: nfs_rename() should not have to flush out writebacks\n ...\n" }, { "commit": "0a8ebba943dd89bdd57c5dab5a66932f690847d9", "tree": "b7ef484c9ecb62ebae09c6739fe016d9954cf243", "parents": [ "1b924e5f878e3cd62a20bd8dbf3b911a40185a99" ], "author": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Sat Jul 31 14:29:06 2010 -0400" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Tue Aug 03 22:06:41 2010 -0400" }, "message": "NFS: nfs_rename() should not have to flush out writebacks\n\nWe don\u0027t really support nfs servers that invalidate the file handle after a\nrename, so precautions such as flushing out dirty data before renaming the\nfile are superfluous.\n\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "9cfcac810e8993fa7a5bfd24b1a21f1dbbb03a7b", "tree": "86fae80c744e46b15b8eb9aa23fead7e63a64159", "parents": [ "692a8a231b212dfc68f612956d63f34abf098e0f" ], "author": { "name": "Eric Paris", "email": "eparis@redhat.com", "time": "Fri Jul 23 11:43:51 2010 -0400" }, "committer": { "name": "James Morris", "email": "jmorris@namei.org", "time": "Mon Aug 02 15:35:06 2010 +1000" }, "message": "vfs: re-introduce MAY_CHDIR\n\nCurrently MAY_ACCESS means that filesystems must check the permissions\nright then and not rely on cached results or the results of future\noperations on the object.

Open 2 xterm sessions\n2. From one of the xterm session, do \"ssh -X \u003cremote host\u003e\"\n3. \"stat ~/.Xauthority\" on the remote SSH session\n4. Close the two xterm sessions\n5. On the server do a \"stat ~/.Xauthority\"\n6. Now on the client, try to open xterm\nThis will fail.\n\nEven if the filehandle had become stale, the NFS client should invalidate\nthe cache/inode and should repeat LOOKUP. Looking at the packet capture when\nthe failure occurs shows that there were two subsequent ACCESS() calls with\nthe same filehandle and both fails with -ESTALE error.\n\nI have tested the fix below. Now the client issue a LOOKUP after the\nACCESS() call fails with -ESTALE. If all this makes sense to you, can you\nconsider this for inclusion?\n\nThanks,\n\n\nIf the server returns an -ESTALE error due to stale filehandle in response to\nan ACCESS() call, we need to invalidate the cache and inode so that LOOKUP()\ncan be retried.
