dlm: fix rcom_names message to self

2008-02-21T21:19:54+00:00

The recent patch to validate data lengths in rcom_names messages
failed to account for fake messages a node directs to itself before
ever sending it.  In this case we need to fill in the message length
in the header for the validation code to use.

dlm: fix dlm_dir_lookup() handling of too long names

2008-02-04T07:30:19+00:00

... those can happen and BUG() from DLM_ASSERT() in allocate_direntry() is
not a good way to handle them.

dlm: make find_rsb() fail gracefully when namelen is too large

2008-02-04T07:26:31+00:00

We *can* get there from receive_request() and dlm_recover_master_copy()
with namelen too large if incoming request is invalid; BUG() from
DLM_ASSERT() in allocate_rsb() is a bit excessive reaction to that
and in case of dlm_recover_master_copy() we would actually oops before
that while calculating hash of up to 64Kb worth of data - with data
actually being 64 _bytes_ in kmalloc()'ed struct.
