| | | | | | | | | | | | | | | | | | | | The new behaviour is enabled using the new module parameter 'nfs4_disable_idmapping'.

| * pnfs: fix pnfs lock inversion of i_lock and cl_lockFred Isaman2011-03-112-18/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The pnfs code was using throughout the lock order i_lock, cl_lock. This conflicts with the nfs delegation code. Rework the pnfs code to avoid taking both locks simultaneously. Currently the code takes the double lock to add/remove the layout to a nfs_client list, while atomically checking that the list of lsegs is empty. To avoid this, we rely on existing serializations. When a layout is initialized with lseg count equal zero, LAYOUTGET's openstateid serialization is in effect, making it safe to assume it stays zero unless we change it. And once a layout's lseg count drops to zero, it is set as DESTROYED and so will stay at zero.

| * pnfs: avoid incorrect use of layout stateidFred Isaman2011-03-111-3/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code could violate the following from RFC5661, section 12.5.3: "Once a client has no more layouts on a file, the layout stateid is no longer valid and MUST NOT be used." This can occur when a layout already has a lseg, starts another non-everlapping LAYOUTGET, and a CB_LAYOUTRECALL for the existing lseg is processed before we hit pnfs_layout_process(). Solve by setting, each time the client has no more lsegs for a file, a flag which blocks further use of the layout and triggers its removal. This also fixes a second bug which occurs in the same instance as above. If we actually use pnfs_layout_process, we add the new lseg to the layout, but the layout has been removed from the nfs_client list by the intervening CB_LAYOUTRECALL and will not be added back. Thus the newly acquired lseg will not be properly returned in the event of a subsequent CB_LAYOUTRECALL.
