Trond Myklebust 0f38b873ae SUNRPC: Use GFP_NOFS when allocating credentials
Since the credentials may be allocated during the call to rpc_new_task(),
which again may be called by a memory allocator...

Trond Myklebust 78ea323be6 NFSv4: Don't use cred->cr_ops->cr_name in nfs4_proc_setclientid()
With the recent change to generic creds, we can no longer use
cred->cr_ops->cr_name to distinguish between RPCSEC_GSS principals and
AUTH_SYS/AUTH_NULL identities. Replace it with the rpc_authops->au_name
instead...

Trond Myklebust 5c691044ec SUNRPC: Add an rpc_credop callback for binding a credential to an rpc_task
We need the ability to treat 'generic' creds specially, since they want to
bind instances of the auth cred instead of binding themselves.

Trond Myklebust af09383577 SUNRPC: Fix RPCAUTH_LOOKUP_ROOTCREDS
The current RPCAUTH_LOOKUP_ROOTCREDS flag only works for AUTH_SYS
authentication, and then only as a special case in the code. This patch
removes the auth_sys special casing, and replaces it with generic code.

Trond Myklebust 1be27f3660 SUNRPC: Remove the tk_auth macro...
We should almost always be deferencing the rpc_auth struct by means of the
credential's cr_auth field instead of the rpc_clnt->cl_auth anyway. Fix up
that historical mistake, and remove the macro that propagated it.

Trond Myklebust 3ab9bb7243 SUNRPC: Fix a memory leak in the auth credcache code
The leak only affects the RPCSEC_GSS caches, since they are the only ones
that are dynamically allocated...
Rename the existing rpcauth_free_credcache() to rpcauth_clear_credcache()
in order to better describe its role, then add a new function
rpcauth_destroy_credcache() that actually frees the cache in addition to
clearing it out.

Also move the call to destroy the credcache in gss_destroy() to come before
the rpc upcall pipe is unlinked.

Trond Myklebust 4a8c1344dc SUNRPC: Add a backpointer from the struct rpc_cred to the rpc_auth
Cleans up an issue whereby rpcsec_gss uses the rpc_clnt->cl_auth. If we want
to be able to add several rpc_auths to a single rpc_clnt, then this abuse
must go.

Trond Myklebust 8a3177604b SUNRPC: Fix a lock recursion in the auth_gss downcall
When we look up a new cred in the auth_gss downcall so that we can stuff
 the credcache, we do not want that lookup to queue up an upcall in order
 to initialise it. To do an upcall here not only redundant, but since we
 are already holding the inode->i_mutex, it will trigger a lock recursion.

 This patch allows rpcauth cache searches to indicate that they can cope
 with uninitialised credentials.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
