Eliminate nfs_server::client_sys in favour of nfs_client::cl_rpcclient as we only really need one per server that we're talking to since it doesn't have any security on it. The retransmission management variables are also moved to the common struct as they're required to set up the cl_rpcclient connection. The NFS2/3 client and client_acl connections are thenceforth derived by cloning the cl_rpcclient connection and post-applying the authorisation flavour. The code for setting up the initial common connection has been moved to client.c as nfs_create_rpc_client(). All the NFS program definition tables are also moved there as that's where they're now required rather than super.c. Signed-Off-By:

Use the nominated dentry's superblock directly in the NFS statfs() op to get a file handle, rather than using s_root (which will become a dummy dentry in a future patch). Signed-Off-By:

David Howells authored
Generalise the nfs_client structure by: (1) Moving nfs_client to a more general place (nfs_fs_sb.h). (2) Renaming its maintenance routines to be non-NFS4 specific. (3) Move those maintenance routines to a new non-NFS4 specific file (client.c) and move the declarations to internal.h. (4) Make nfs_find/get_client() take a full sockaddr_in to include the port number (will be required for NFS2/3). (5) Make nfs_find/get_client() take the NFS protocol version (again will be required to differentiate NFS2, 3 & 4 client records). Also: (6) Make nfs_client construction proceed akin to inodes, marking them as under construction and providing a function to indicate completion. (7) Make nfs_get_client() wait interruptibly if it finds a client that it can share, but that client is currently being constructed. (8) Make nfs4_create_client() use (6) and (7) instead of locking cl_sem. Signed-Off-By: -

Fix ups for the splitting of the superblock stuff out of fs/nfs/inode.c, including: (*) Move the callback tcpport module param into callback.c. (*) Move the idmap cache timeout module param into idmap.c. (*) Changes to internal.h: (*) namespace-nfs4.c was renamed to nfs4namespace.c. (*) nfs_stat_to_errno() is in nfs2xdr.c, not nfs4xdr.c. (*) nfs4xdr.c is contingent on CONFIG_NFS_V4. (*) nfs4_path() is only uses if CONFIG_NFS_V4 is set. Plus also: (*) The sec_flavours[] table should really be const. Signed-Off-By: -

The attached patch adds a new directory cache management function that prepares a disconnected anonymous function to be connected into the dentry tree. The anonymous dentry is transferred the name and parentage from another dentry. The following changes were made in [try #2]: (*) d_materialise_dentry() now switches the parentage of the two nodes around correctly when one or other of them is self-referential. The following changes were made in [try #7]: (*) d_instantiate_unique() has had the interior part split out as function __d_instantiate_unique(). Callers of this latter function must be holding the appropriate locks. (*) _d_rehash() has been added as a wrapper around __d_rehash() to call it with the most obvious hash list (the one from the name). d_rehash() now calls _d_rehash(). (*) d_materialise_dentry() is now __d_materialise_dentry() and is static. (*) d_materialise_unique() added to perform the combination of d_find_alias(), d_materialise_dentry() and d_add_unique() that the NFS client was doing twice, all within a single dcache_lock critical section. This reduces the number of times two different spinlocks were being accessed. The following further changes were made: (*) Add the dentries onto their parents d_subdirs lists. Signed-Off-By: -

A pinned inode may in theory end up filling memory with cached ACCESS calls. This patch ensures that the VM may shrink away the cache in these particular cases. The shrinker works by iterating through the list of inodes on the global nfs_access_lru_list, and removing the least recently used access cache entry until it is done (or until the entire cache is empty).

The current access cache only allows one entry at a time to be cached for each inode. Add a per-inode red-black tree in order to allow more than one to be cached at a time. Should significantly cut down the time spent in path traversal for shared directories such as ${PATH}, /usr/share, etc. Signed-off-by: -

Back when pci_dev had base_address[], loop of form base = &...->base_address[0]; for (.....) { ... *base++ = addr; } was fine, but when that array got spread in ->resource[...].start replacing the initialization with base = &...->resource[0].start; was not a sufficient modification.

When ipoib_ib_dev_flush() is called because of a port event, the driver needs to rejoin all multicast groups, since the flush will call ipoib_mcast_dev_flush() (via ipoib_ib_dev_down()). Otherwise no (non-broadcast) multicast groups will be rejoined until the networking core calls ->set_multicast_list again, and so multicast reception will be broken for potentially a long time.

RFC 4391 ("Transmission of IP over InfiniBand (IPoIB)") says: If the IB multicast group does not already exist, one must be created first with the IPoIB link MTU. The MGID MUST use the same P_Key, Q_Key, SL, MTU, and HopLimit as those used in the broadcast-GID. The rest of attributes SHOULD follow the values used in the broadcast-GID as well. However, the current IPoIB driver is only setting the attributes required by the InfiniBand spec to create a multicast group, so in particular the MTU and HopLimit are not being set. Add these attributes when creating MCGs, and also set the Rate attribute, since IPoIB pays attention to that attribute as well. Signed-off-by:
