Pull NFS client updates from Trond Myklebust: "Highlights include: - Fix NFSv4 recovery so that it doesn't recover lost locks in cases such as lease loss due to a network partition, where doing so may result in data corruption. Add a kernel parameter to control choice of legacy behaviour or not. - Performance improvements when 2 processes are writing to the same file. - Flush data to disk when an RPCSEC_GSS session timeout is imminent. - Implement NFSv4.1 SP4_MACH_CRED state protection to prevent other NFS clients from being able to manipulate our lease and file locking state. - Allow sharing of RPCSEC_GSS caches between different rpc clients. - Fix the broken NFSv4 security auto-negotiation between client and server. - Fix rmdir() to wait for outstanding sillyrename unlinks to complete - Add a tracepoint framework for debugging NFSv4 state recovery issues. - Add tracing to the generic NFS layer. - Add tracing for the SUNRPC socket connection state. - Clean up the rpc_pipefs mount/umount event management. - Merge more patches from Chuck in preparation for NFSv4 migration support" * tag 'nfs-for-3.12-1' of git://git.linux-nfs.org/projects/trondmy/linux-nfs: (107 commits) NFSv4: use mach cred for SECINFO_NO_NAME w/ integrity NFS: nfs_compare_super shouldn't check the auth flavour unless 'sec=' was set NFSv4: Allow security autonegotiation for submounts NFSv4: Disallow security negotiation for lookups when 'sec=' is specified NFSv4: Fix security auto-negotiation NFS: Clean up nfs_parse_security_flavors() NFS: Clean up the auth flavour array mess NFSv4.1 Use MDS auth flavor for data server connection NFS: Don't check lock owner compatability unless file is locked (part 2) NFS: Don't check lock owner compatibility in writes unless file is locked nfs4: Map NFS4ERR_WRONG_CRED to EPERM nfs4.1: Add SP4_MACH_CRED write and commit support nfs4.1: Add SP4_MACH_CRED stateid support nfs4.1: Add SP4_MACH_CRED secinfo support nfs4.1: Add SP4_MACH_CRED cleanup support nfs4.1: Add state protection handler nfs4.1: Minimal SP4_MACH_CRED implementation SUNRPC: Replace pointer values with task->tk_pid and rpc_clnt->cl_clid SUNRPC: Add an identifier for struct rpc_clnt SUNRPC: Ensure rpc_task->tk_pid is available for tracepoints ...

SUNRPC new rpc_credops to test credential expiry

2013-09-03T19:25:08Z

This patch provides the RPC layer helper functions to allow NFS to manage data in the face of expired credentials - such as avoiding buffered WRITEs and COMMITs when the gss context will expire before the WRITEs are flushed and COMMITs are sent. These helper functions enable checking the expiration of an underlying credential key for a generic rpc credential, e.g. the gss_cred gss context gc_expiry which for Kerberos is set to the remaining TGT lifetime. A new rpc_authops key_timeout is only defined for the generic auth. A new rpc_credops crkey_to_expire is only defined for the generic cred. A new rpc_credops crkey_timeout is only defined for the gss cred. Set a credential key expiry watermark, RPC_KEY_EXPIRE_TIMEO set to 240 seconds as a default and can be set via a module parameter as we need to ensure there is time for any dirty data to be flushed. If key_timeout is called on a credential with an underlying credential key that will expire within watermark seconds, we set the RPC_CRED_KEY_EXPIRE_SOON flag in the generic_cred acred so that the NFS layer can clean up prior to key expiration. Checking a generic credential's underlying credential involves a cred lookup. To avoid this lookup in the normal case when the underlying credential has a key that is valid (before the watermark), a notify flag is set in the generic credential the first time the key_timeout is called. The generic credential then stops checking the underlying credential key expiry, and the underlying credential (gss_cred) match routine then checks the key expiration upon each normal use and sets a flag in the associated generic credential only when the key expiration is within the watermark. This in turn signals the generic credential key_timeout to perform the extra credential lookup thereafter. Signed-off-by: Andy Adamson Signed-off-by: Trond Myklebust

Merge tag 'v3.11-rc5' into for-3.12 branch

2013-08-30T20:42:49Z

For testing purposes I want some nfs and nfsd bugfixes (specifically, 58cd57bfd9db3bc213bf9d6a10920f82095f0114 and previous nfsd patches, and Trond's 4f3cc4809a98a165a9708b72b47de71643797bbd).
