2011-06-16NFSv4: Fix a readdir regressionTrond Myklebust
Commit 7ebb9315 (NFS: use secinfo when crossing mountpoints) introduces a regression when decoding an NFSv4 readdir entry that sets the rdattr_error field. By treating the resulting value as if it is a decoding error, the current code may cause us to skip valid readdir entries.

2011-04-27NFSv4: Ensure we request the ordinary fileid when doing readdirplusTrond Myklebust
When readdir() returns a directory entry for the root of a mounted filesystem, Linux follows the old convention of returning the inode number of the covered directory (despite newer versions of POSIX declaring that this is a bug). To ensure this continues to work, the NFSv4 readdir implementation requests the 'mounted-on-fileid' from the server. However, readdirplus also needs to instantiate an inode for this entry, and for that, we also need to request the real fileid as per this patch.

2011-04-13NFS: Use correct variable for page bounds checkingBryan Schumaker
While decoding a secinfo reply, I store the list of supported sec flavors on a page accessible through res->flavors. Before reading each new flavor, I do some math to determine if there is enough space left on this page, and I break out of my read look if there isn't. In order to perform this check correctly, I need to use the address of res->flavors, rather than the address of res. When this loop was broken early I lied to the caller and told them that the entire list had been decoded. This could lead to problems if the caller tries to use any the garbage data claiming to be a valid sec flavor. I fixed this by using res->flavors->num_flavors as a counter, incrementing it every time a sec flavor is successfully decoded.

2011-01-28NFS: NFSv4 readdir loses entriesChuck Lever
On recent 2.6.38-rc kernels, connectathon basic test 6 fails on NFSv4 mounts of OpenSolaris with something like: > ./test6: readdir > ./test6: (/mnt/klimt/matisse.test) didn't read expected 'file.12' dir entry, pass 0 > ./test6: (/mnt/klimt/matisse.test) didn't read expected 'file.82' dir entry, pass 0 > ./test6: (/mnt/klimt/matisse.test) didn't read expected 'file.164' dir entry, pass 0 > ./test6: (/mnt/klimt/matisse.test) Test failed with 3 errors > basic tests failed > Tests failed, leaving /mnt/klimt mounted > [cel@matisse cthon04]$ I narrowed the problem down to nfs4_decode_dirent() reporting that the decode buffer had overflowed while decoding the entries for those missing files. verify_attr_len() assumes both it's pointer arguments reside on the same page. When these arguments point to locations on two different pages, verify_attr_len() can report false errors. This can happen now that a large NFSv4 readdir result can span pages. We have reasonably good checking in nfs4_decode_dirent() anyway, so it should be safe to simply remove the extra checking. At a guess, this was introduced by commit 6650239a, "NFS: Don't use vm_map_ram() in readdir".

2011-01-10NFS: Don't use vm_map_ram() in readdirTrond Myklebust
vm_map_ram() is not available on NOMMU platforms, and causes trouble on incoherrent architectures such as ARM when we access the page data through both the direct and the virtual mapping. The alternative is to use the direct mapping to access page data for the case when we are not crossing a page boundary, but to copy the data into a linear scratch buffer when we are accessing data that spans page boundaries.

2011-01-06NFSv4: Ensure continued open and lockowner name uniquenessTrond Myklebust
In order to enable migration support, we will want to move some of the structures that are subject to migration into the struct nfs_server. In particular, if we are to move the state_owner and state_owner_id to being a per-filesystem structure, then we should label the resulting open/lock owners with a per-filesytem label to ensure global uniqueness. This patch does so by adding the super block s_dev to the open/lock owner name. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2011-01-06pnfs: serialize LAYOUTGET(openstateid)Fred Isaman
We shouldn't send a LAYOUTGET(openstateid) unless all outstanding RPCs using the previous stateid are completed. This requires choosing the stateid to encode earlier, so we can abort if one is not available (we want to use the open stateid, but a LAYOUTGET is already out using it), and adding a count of the number of outstanding rpc calls using layout state (which for now consist solely of LAYOUTGETs).

2011-01-06pnfs: change layout state seqlock to a spinlockFred Isaman
This prepares for future changes, where the layout state needs to change atomically with several other variables. In particular, it will need to know if lo->segs is empty, as we test that instead of manipulating the NFS_LAYOUT_STATEID_SET bit. Moreover, the layoutstateid is not really a read-mostly structure, as it is written almost as often as it is read. The behavior of pnfs_get_layout_stateid is also slightly changed, so that it no longer changes the stateid. Its name is changed to +pnfs_choose_layoutget_stateid.

2010-12-16NFS: Simplify ->decode_dirent() calling sequenceChuck Lever
Clean up. The pointer returned by ->decode_dirent() is no longer used as a pointer. The only call site (xdr_decode() in fs/nfs/dir.c) simply extracts the errno value encoded in the pointer. Replace the returned pointer with a standard integer errno return value. Also, pass the "server" argument as part of the nfs_entry instead of as a separate parameter. It's faster to derive "server" in nfs_readdir_xdr_to_array() since we already have the directory's inode handy. "server" ought to be invariant for a set of entries in the same directory, right? The legacy versions of decode_dirent() don't use "server" anyway, so it's wasted work for them to derive and pass "server" for each entry.
