Michal Nazarewicz 358bd68cbd staging: lustre: fix potential NULL pointer dereference
The rest of the code seem to imply that rmf_dumper may indeed be
NULL.  Change the code so that dumping is not even considered if
rmf_dumper callback is not set.

Andrew Perepechko 7fc1f831d8 staging/lustre/llite: extended attribute cache
This patch implements an extended attribute cache for
a Lustre client. It is organized as a write-through
cache: reads are performed from cache, updates are sent
synchronously to the MDS. An additional inode bit
MDS_INODELOCK_XATTR is added to protect the cache.

Amir Shehata 3c92a0bf4d staging/lustre/ptlrpc: Fix a crash when dereferencing NULL pointer
When a system runs out of memory and the function
ptlrpc_register_bulk() is called from ptl_send_rpc() the call to
LNetMEAttach() fails due to failure to allocate memory.  This forces
the code into an error path, which most probably previously went
untested.  The error path:
if (rc != 0) {
        CERROR("%s: LNetMEAttach failed x"LPU64"/%d: rc = %dn",
                desc->bd_export->exp_obd->obd_name, xid,
                posted_md, rc);
        break;
}
This print assumes that desc->bd_export is not NULL.  However, it is.
In fact it is expected to be NULL.  desc->bd_import is the correct
structure to access in this case.

John L. Hammond 1e8a576eb3 staging/lustre/llite: don't check for O_CREAT in it_create_mode
ll_lookup_it() checks for O_CREAT in struct lookup_intent's
it_create_mode member which is nonsensical, as it_create_mode is used
for file mode bits (S_IFREG, S_IRUSR, ...). Fix this by just checking
for IT_CREATE in it_op. This will not affect the behavior of either
function, since if O_CREATE (0100) is actually set in o_create_mode
then IT_CREATE must have been set in it_op. In ll_atomic_open() check
for O_CREAT in the open_flags parameter rather than testing mode.

Patrick Farrell ad8dbc93a4 staging/lustre/nfs: writing to new files will return ENOENT
This happend with SLES11SP2 Lustre client, which in turn acts as an
NFS server, exporting a subtree of an Lustre fs through NFS.

We detected that whenever we are writing to a new file using, fx,
'echo blah > newfile', it will return ENOENT error. We found
out that this was caused by the anonymous dentry. In SLESS11SP2,
anonymous dentries are assigned '/' as the name, instead of an
empty string. When MDT handles the intent_open call, it will look
up the obj by the name if it is not an empty string, and thus
couldn't find it.

As MDS_OPEN_BY_FID is always set on this request, we never need
to send the name in this request.  The fid is already available
and should be used in case the file has been renamed.

Mikhail Pershin 65f1c7816d staging/lustre/server: use unified request handler for MGS
- Unify request handler. It finds target for particular request and
  calls appropriate handler for it. Generic handlers are moved to
  the unified target code. The tgt_session_info is introduced to
  store all request-related data and passed to all handlers.
- Pack reply in llog server functions early and use err_serious()
- remove obsoleted llog_origin_handle_cancel(), it is not used
  anymore
- remove push_ctxt/pop_ctxt from llog server function, it is based
  on OSD now.

Amir Shehata 4f317748f2 staging/lustre/lnet: Fix assert on empty group in selftest module
The core of the issue is that the selftest module doesn't sanitize its
own API, but it depends on lst utility to do such checks.  As a result
this issue manifests itself in this particular LU through an assert
on an empty group.  If the NID is misspelled then an empty group is
added.  An error output is provided, but if that's never checked in a
batch script, as is the case with this issue, then the script will try
to add an empty group to a test to run in a batch, and that will cause
an assert

The fix is two fold.  Ensure that lst utility checks that a group is
added with at least one node.  If not the group is subsequently
deleted.  And the add_test command would fail, since the group no
longer exists.

The second fix is to ensure that the kernel module itself sanitizes
its own API in this particular case, so that if a different utility is
used other than lst to communicate with the selftest kernel module
then this error would be caught.  This fix looks up the batch and the
groups, src and dst, in the ioctl handle and sanitizes that input at
this point.  If the group looked up either doesn't exist or doesn't
have at least one ACTIVE node, then the command fails.

NOTE:there are many other cases in the code where the selftest kernel
module doesn't check for sanity of the input, but depends totally on
the lst module to do such checks.  Particularly around length of
strings passed in.  Thus it is possible to crash the selftest module
if someone tries to create another userspace app to communicate with
the selftest kernel module without ensuring sanity of the params sent
to the kernel module.  In effect, it's always assumed that lst is the
front end for selftest and no other front end is to be used.

Andreas Dilger 6d95e0481b staging/lustre/ldlm: fix resource/fid check, use DLDLMRES
In ll_md_blocking_ast() the FID/resource comparison is incorrectly
checking for fid_ver() stored in res_id.name[2] instead of name[1]
changed since http://review.whamcloud.com/2271 (commit 4f91d5161d00)
landed.  This does not impact current clients, since name[2] and
fid_ver() are always zero, but it could cause problems in the future.

In ldlm_cli_enqueue_fini() use ldlm_res_eq() instead of comparing
each of the resource fields separately.

Use DLDLMRES/PLDLMRES when printing resource names everywhere.

JC Lafoucriere 5ea17d6cb9 staging/lustre/llite: Access to released file triggers a restore
When a client accesses data in a released file,
or truncate it, client must trig a restore request.
During this restore, the client must not glimpse and
must use size from MDT. To bring the "restore is running"
information on the client we add a new t_state bit field
to mdt_info which will be used to carry transient file state.
To memorise this information in the inode we add a new flag
LLIF_FILE_RESTORING.
