[PATCH] SUNRPC: Fix potential deadlock in RPC code

2006-03-14T15:57:18+00:00

In rpc_wake_up() and rpc_wake_up_status(), it is possible for the call to
__rpc_wake_up_task() to fail if another thread happens to be calling
rpc_wake_up_task() on the same rpc_task.

Problem noticed by Bruno Faccini.

SUNRPC: Move upcall out of auth->au_ops->crcreate()

2006-02-01T17:52:25+00:00

 This fixes a bug whereby if two processes try to look up the same auth_gss
 credential, they may end up creating two creds, and triggering two upcalls
 because the upcall is performed before the credential is added to the
 credcache.

SUNRPC: rpc_timeout_upcall_queue should not sleep

2006-02-01T17:52:24+00:00

 The function rpc_timeout_upcall_queue runs from a workqueue, and hence
 sleeping is not recommended. Convert the protection of the upcall queue
 from being mutex-based to being spinlock-based.

SUNRPC: Fix a lock recursion in the auth_gss downcall

2006-02-01T17:52:23+00:00

 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.

[PATCH] svcrpc: gss: server context init failure handling

2006-01-19T03:20:25+00:00

We require the server's gssd to create a completed context before asking the
kernel to send a final context init reply.  However, gssd could be buggy, or
under some bizarre circumstances we might purge the context from our cache
before we get the chance to use it here.

Handle this case by returning GSS_S_NO_CONTEXT to the client.

Also move the relevant code here to a separate function rather than nesting
excessively.

[PATCH] svcrpc: gss: handle the GSS_S_CONTINUE

2006-01-19T03:20:25+00:00

Kerberos context initiation is handled in a single round trip, but other
mechanisms (including spkm3) may require more, so we need to handle the
GSS_S_CONTINUE case in svcauth_gss_accept.  Send a null verifier.
