2014-07-13nfs4: copy acceptor name from context to nfs_clientJeff Layton1-0/+1
The current CB_COMPOUND handling code tries to compare the principal name of the request with the cl_hostname in the client. This is not guaranteed to ever work, particularly if the client happened to mount a CNAME of the server or a non-fqdn. Fix this by instead comparing the cr_principal string with the acceptor name that we get from gssd. In the event that gssd didn't send one down (i.e. it was too old), then we fall back to trying to use the cl_hostname as we do today.

NFS_SB() returns the pointer to an nfs_server struct, given a pointer to a super_block. But we have no way to go back the other way.

2013-09-06NFSv4.1 Use MDS auth flavor for data server connectionAndy Adamson1-0/+1
Commit 4edaa308 "NFS: Use "krb5i" to establish NFSv4 state whenever possible" uses the nfs_client cl_rpcclient for all state management operations, and will use krb5i or auth_sys with no regard to the mount command authflavor choice. The MDS, as any NFSv4.1 mount point, uses the nfs_server rpc client for all non-state management operations with a different nfs_server for each fsid encountered traversing the mount point, each with a potentially different auth flavor. pNFS data servers are not mounted in the normal sense as there is no associated nfs_server structure. Data servers can also export multiple fsids, each with a potentially different auth flavor. Data servers need to use the same authflavor as the MDS server rpc client for non-state management operations. Populate a list of rpc clients with the MDS server rpc client auth flavor for the DS to use.

2013-09-05nfs4.1: Minimal SP4_MACH_CRED implementationWeston Andros Adamson1-0/+4
This is a minimal client side implementation of SP4_MACH_CRED. It will attempt to negotiate SP4_MACH_CRED iff the EXCHANGE_ID is using krb5i or krb5p auth. SP4_MACH_CRED will be used if the server supports the minimal operations: BIND_CONN_TO_SESSION EXCHANGE_ID CREATE_SESSION DESTROY_SESSION DESTROY_CLIENTID This patch only includes the EXCHANGE_ID negotiation code because the client will already use the machine cred for these operations. If the server doesn't support SP4_MACH_CRED or doesn't support the minimal operations, the exchange id will be resent with SP4_NONE.

2012-12-06NFSv4.1: Ensure that the client tracks the server target_highest_slotidTrond Myklebust1-2/+3
Dynamic slot allocation in NFSv4.1 depends on the client being able to track the server's target value for the highest slotid in the slot table. See the reference in Section 2.10.6.1 of RFC5661. To avoid ordering problems in the case where 2 SEQUENCE replies contain conflicting updates to this target value, we also introduce a generation counter, to track whether or not an RPC containing a SEQUENCE operation was launched before or after the last update. Also rename the nfs4_slot_table target_max_slots field to 'target_highest_slotid' to avoid confusion with a slot table size or number of slots.

2012-10-02NFS: Discover NFSv4 server trunking when mountingChuck Lever1-0/+1
"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.

2012-10-02NFS: Introduce "migration" mount optionChuck Lever1-0/+2
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.

This patch exports symbols needed by the v4 module. In addition, I also switch over to using IS_ENABLED() to check if CONFIG_NFS_V4 or CONFIG_NFS_V4_MODULE are set.

2012-07-16NFS: Treat NFS4ERR_CLID_INUSE as a fatal errorChuck Lever1-2/+1
For NFSv4 minor version 0, currently the cl_id_uniquifier allows the Linux client to generate a unique nfs_client_id4 string whenever a server replies with NFS4ERR_CLID_INUSE. This implementation seems to be based on a flawed reading of RFC 3530. NFS4ERR_CLID_INUSE actually means that the client has presented this nfs_client_id4 string with a different principal at some time in the past, and that lease is still in use on the server. For a Linux client this might be rather difficult to achieve: the authentication flavor is named right in the nfs_client_id4.id string. If we change flavors, we change strings automatically. So, practically speaking, NFS4ERR_CLID_INUSE means there is some other client using our string. There is not much that can be done to recover automatically. Let's make it a permanent error. Remove the recovery logic in nfs4_proc_setclientid(), and remove the cl_id_uniquifier field from the nfs_client data structure. And, remove the authentication flavor from the nfs_client_id4 string. Keeping the authentication flavor in the nfs_client_id4.id string means that we could have a separate lease for each authentication flavor used by mounts on the client. But we want just one lease for all the mounts on this client. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2012-06-18NFSv4.1: Fix umount when filelayout DS is also the MDSTrond Myklebust1-0/+1
Currently there is a 'chicken and egg' issue when the DS is also the mounted MDS. The nfs_match_client() reference from nfs4_set_ds_client bumps the cl_count, the nfs_client is not freed at umount, and nfs4_deviceid_purge_client is not called to dereference the MDS usage of a deviceid which holds a reference to the DS nfs_client. The result is the umount program returns, but the nfs_client is not freed, and the cl_session hearbeat continues. The MDS (and all other nfs mounts) lose their last nfs_client reference in nfs_free_server when the last nfs_server (fsid) is umounted. The file layout DS lose their last nfs_client reference in destroy_ds when the last deviceid referencing the data server is put and destroy_ds is called. This is triggered by a call to nfs4_deviceid_purge_client which removes references to a pNFS deviceid used by an MDS mount. The fix is to track how many pnfs enabled filesystems are mounted from this server, and then to purge the device id cache once that count reaches zero.

2012-05-23NFS: Always use the same SETCLIENTID boot verifierChuck Lever1-3/+0
Currently our NFS client assigns a unique SETCLIENTID boot verifier for each server IP address it knows about. It's set to CURRENT_TIME when the struct nfs_client for that server IP is created. During the SETCLIENTID operation, our client also presents an nfs_client_id4 string to servers, as an identifier on which the server can hang all of this client's NFSv4 state. Our client's nfs_client_id4 string is unique for each server IP address. An NFSv4 server is obligated to wipe all NFSv4 state associated with an nfs_client_id4 string when the client presents the same nfs_client_id4 string along with a changed SETCLIENTID boot verifier. When our client unmounts the last of a server's shares, it destroys that server's struct nfs_client. The next time the client mounts that NFS server, it creates a fresh struct nfs_client with a fresh boot verifier. On seeing the fresh verifer, the server wipes any previous NFSv4 state associated with that nfs_client_id4. However, NFSv4.1 clients are supposed to present the same nfs_client_id4 string to all servers. And, to support Transparent State Migration, the same nfs_client_id4 string should be presented to all NFSv4.0 servers so they recognize that migrated state for this client belongs with state a server may already have for this client. (This is known as the Uniform Client String model). If the nfs_client_id4 string is the same but the boot verifier changes for each server IP address, SETCLIENTID and EXCHANGE_ID operations from such a client could unintentionally result in a server wiping a client's previously obtained lease. Thus, if our NFS client is going to use a fixed nfs_client_id4 string, either for NFSv4.0 or NFSv4.1 mounts, our NFS client should use a boot verifier that does not change depending on server IP address. Replace our current per-nfs_client boot verifier with a per-nfs_net boot verifier. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
