2012-10-02sfc: Fix loopback self-test with separate_tx_channels=1Ben Hutchings
The loopback self-test iterates over all the TX queues of channel 0, which is not very interesting when that's an RX-only channel. Signed-off-by: Ben Hutchings <bhutchings@solarflre.com>
2012-10-02sfc: Fix MCDI structure field lookupBen Hutchings
The least significant bit number (LBN) of a field within an MCDI structure is counted from the start of the structure, not the containing dword. In MCDI_ARRAY_FIELD() we need to mask it rather than using the usual EFX_DWORD_FIELD() macro. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

2012-10-02sfc: Fix null function pointer in efx_sriov_channel_typeBen Hutchings
Commit c31e5f9 ('sfc: Add channel specific receive_skb handler and post_remove callback') added the function pointer field efx_channel_type::post_remove and an unconditional call through it. This field should have been initialised to efx_channel_dummy_op_void in the existing instances of efx_channel_type, but this was only done in efx_default_channel_type. Consequently, if a device has SR-IOV enabled then removing the driver or device will result in an oops. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

2012-10-01NFS: Add nfs4_unique_id boot parameterChuck Lever
An optional boot parameter is introduced to allow client administrators to specify a string that the Linux NFS client can insert into its nfs_client_id4 id string, to make it both more globally unique, and to ensure that it doesn't change even if the client's nodename changes. If this boot parameter is not specified, the client's nodename is used, as before. Client installation procedures can create a unique string (typically, a UUID) which remains unchanged during the lifetime of that client instance. This works just like creating a UUID for the label of the system's root and boot volumes.

2012-10-01NFS: Discover NFSv4 server trunking when mountingChuck Lever
"Server trunking" is a fancy named for a multi-homed NFS server. Trunking might occur if a client sends NFS requests for a single workload to multiple network interfaces on the same server. There are some implications for NFSv4 state management that make it useful for a client to know if a single NFSv4 server instance is multi-homed. (Note this is only a consideration for NFSv4, not for legacy versions of NFS, which are stateless). If a client cares about server trunking, no NFSv4 operations can proceed until that client determines who it is talking to. Thus server IP trunking discovery must be done when the client first encounters an unfamiliar server IP address. The nfs_get_client() function walks the nfs_client_list and matches on server IP address. The outcome of that walk tells us immediately if we have an unfamiliar server IP address. It invokes nfs_init_client() in this case. Thus, nfs4_init_client() is a good spot to perform trunking discovery. Discovery requires a client to establish a fresh client ID, so our client will now send SETCLIENTID or EXCHANGE_ID as the first NFS operation after a successful ping, rather than waiting for an application to perform an operation that requires NFSv4 state. The exact process for detecting trunking is different for NFSv4.0 and NFSv4.1, so a minorversion-specific init_client callout method is introduced. CLID_INUSE recovery is important for the trunking discovery process. CLID_INUSE is a sign the server recognizes the client's nfs_client_id4 id string, but the client is using the wrong principal this time for the SETCLIENTID operation. The SETCLIENTID must be retried with a series of different principals until one works, and then the rest of trunking discovery can proceed.

2012-10-01NFS: Use the same nfs_client_id4 for every serverChuck Lever
Currently, when identifying itself to NFS servers, the Linux NFS client uses a unique nfs_client_id4.id string for each server IP address it talks with. For example, when client A talks to server X, the client identifies itself using a string like "AX". The requirements for these strings are specified in detail by RFC 3530 (and bis). This form of client identification presents a problem for Transparent State Migration. When client A's state on server X is migrated to server Y, it continues to be associated with string "AX." But, according to the rules of client string construction above, client A will present string "AY" when communicating with server Y. Server Y thus has no way to know that client A should be associated with the state migrated from server X. "AX" is all but abandoned, interfering with establishing fresh state for client A on server Y. To support transparent state migration, then, NFSv4.0 clients must instead use the same nfs_client_id4.id string to identify themselves to every NFS server; something like "A". Now a client identifies itself as "A" to server X. When a file system on server X transitions to server Y, and client A identifies itself as "A" to server Y, Y will know immediately that the state associated with "A," whether it is native or migrated, is owned by the client, and can merge both into a single lease. As a pre-requisite to adding support for NFSv4 migration to the Linux NFS client, this patch changes the way Linux identifies itself to NFS servers via the SETCLIENTID (NFSv4 minor version 0) and EXCHANGE_ID (NFSv4 minor version 1) operations. In addition to removing the server's IP address from nfs_client_id4, the Linux NFS client will also no longer use its own source IP address as part of the nfs_client_id4 string. On multi-homed clients, the value of this address depends on the address family and network routing used to contact the server, thus it can be different for each server.

2012-10-01NFS: Introduce "migration" mount optionChuck Lever
Currently, the Linux client uses a unique nfs_client_id4.id string when identifying itself to distinct NFS servers. To support transparent state migration, the Linux client will have to use the same nfs_client_id4 string for all servers it communicates with (also known as the "uniform client string" approach). Otherwise NFS servers can not recognize that open and lock state need to be merged after a file system transition. Unfortunately, there are some NFSv4.0 servers currently in the field that do not tolerate the uniform client string approach. Thus, by default, our NFSv4.0 mounts will continue to use the current approach, and we introduce a mount option that switches them to use the uniform model. Client administrators must identify which servers can be mounted with this option. Eventually most NFSv4.0 servers will be able to handle the uniform approach, and we can change the default. The first mount of a server controls the behavior for all subsequent mounts for the lifetime of that set of mounts of that server. After the last mount of that server is gone, the client erases the data structure that tracks the lease. A subsequent lease may then honor a different "migration" setting. This patch adds only the infrastructure for parsing the new mount option. Support for uniform client strings is added in a subsequent patch.

2012-10-01SUNRPC: Introduce rpc_clone_client_set_auth()Chuck Lever
An ULP is supposed to be able to replace a GSS rpc_auth object with another GSS rpc_auth object using rpcauth_create(). However, rpcauth_create() in 3.5 reliably fails with -EEXIST in this case. This is because when gss_create() attempts to create the upcall pipes, sometimes they are already there. For example if a pipe FS mount event occurs, or a previous GSS flavor was in use for this rpc_clnt. It turns out that's not the only problem here. While working on a fix for the above problem, we noticed that replacing an rpc_clnt's rpc_auth is not safe, since dereferencing the cl_auth field is not protected in any way. So we're deprecating the ability of rpcauth_create() to switch an rpc_clnt's security flavor during normal operation. Instead, let's add a fresh API that clones an rpc_clnt and gives the clone a new flavor before it's used. This makes immediate use of the new __rpc_clone_client() helper. This can be used in a similar fashion to rpcauth_create() when a client is hunting for the correct security flavor. Instead of replacing an rpc_clnt's security flavor in a loop, the ULP replaces the whole rpc_clnt. To fix the -EEXIST problem, any ULP logic that relies on replacing an rpc_clnt's rpc_auth with rpcauth_create() must be changed to use this API instead.

2012-10-01NFS: Slow down state manager after an unhandled errorChuck Lever
If the state manager thread is not actually able to fully recover from some situation, it wakes up waiters, who kick off a new state manager thread. Quite often the fresh invocation of the state manager is just as successful. This results in a livelock as the client dumps thousands of NFS requests a second on the network in a vain attempt to recover. Not very friendly. To mitigate this situation, add a delay in the state manager after an unhandled error, so that the client sends just a few requests every second in this case.

It means, that current nsproxy is set to NULL already, but creation of RPC client requires UTS namespace for gaining hostname string. This patch creates reference-counted per-net NSM client on first monitor request and destroys it after last unmonitor request.

2012-10-01lockd: use rpc client's cl_nodename for id encodingStanislav Kinsbursky
Taking hostname from uts namespace if not safe, because this cuold be performind during umount operation on child reaper death. And in this case current->nsproxy is NULL already.
