SUNRPC handle EKEYEXPIRED in call_refreshresult

2012-12-12T20:36:02+00:00

Currently, when an RPCSEC_GSS context has expired or is non-existent
and the users (Kerberos) credentials have also expired or are non-existent,
the client receives the -EKEYEXPIRED error and tries to refresh the context
forever.  If an application is performing I/O, or other work against the share,
the application hangs, and the user is not prompted to refresh/establish their
credentials. This can result in a denial of service for other users.

Users are expected to manage their Kerberos credential lifetimes to mitigate
this issue.

Move the -EKEYEXPIRED handling into the RPC layer. Try tk_cred_retry number
of times to refresh the gss_context, and then return -EACCES to the application.

NFS: Only initialize the ACL client in the v3 case

2012-07-30T23:05:54+00:00

v2 and v4 don't use it, so I create two new nfs_rpc_ops functions to
initialize the ACL client only when we are using v3.

NFS: Create a try_mount rpc op

2012-07-30T23:04:53+00:00

I'm already looking up the nfs subversion in nfs_fs_mount(), so I have
easy access to rpc_ops that used to be difficult to reach.  This allows
me to set up a different mount path for NFS v2/3 and NFS v4.

NFS: Split out NFS v2 inode operations

This patch moves the NFS v2 file and directory inode functions into
files that are only compiled whet CONFIG_NFS_V2 is enabled.

nfs: clean up ->create in nfs_rpc_ops

2012-07-14T12:33:08+00:00

Don't pass nfs_open_context() to ->create().  Only the NFS4 implementation
needed that and only because it wanted to return an open file using open
intents.  That task has been replaced by ->atomic_open so it is not necessary
anymore to pass the context to the create rpc operation.

Despite nfs4_proc_create apparently being okay with a NULL context it Oopses
somewhere down the call chain.  So allocate a context here.

NFS: Create an write_pageio_init() function

2012-06-29T15:46:46+00:00

pNFS needs to select a write function based on the layout driver
currently in use, so I let each NFS version decide how to best handle
initializing writes.

NFS: Create an alloc_client rpc_op

2012-06-29T15:46:46+00:00

This gives NFS v4 a way to set up callbacks and sessions without v2 or
v3 having to do them as well.
