2012-03-26nfsd4: allow numeric idmappingJ. Bruce Fields
Mimic the client side by providing a module parameter that turns off idmapping in the auth_sys case, for backwards compatibility with NFSv2 and NFSv3. Unlike in the client case, we don't have any way to negotiate, since the client can return an error to us if it doesn't like the id that we return to it in (for example) a getattr call. However, it has always been possible for servers to return numeric id's, and as far as we're aware clients have always been able to handle them. Also, in the auth_sys case clients already need to have numeric id's the same between client and server. Therefore we believe it's safe to default this to on; but the module parameter is available to return to previous behavior if this proves to be a problem in some unexpected setup. Signed-off-by: J. Bruce Fields <bfields@redhat.com>

2012-03-26nfsd: add notifier to handle mount/unmount of rpc_pipefs sbJeff Layton

2012-03-26nfsd: add the infrastructure to handle the cld upcallJeff Layton
...and add a mechanism for switching between the "legacy" tracker and the new one. The decision is made by looking to see whether the v4recoverydir exists. If it does, then the legacy client tracker is used. If it's not, then the kernel will create a "cld" pipe in rpc_pipefs. That pipe is used to talk to a daemon for handling the upcall. Most of the data structures for the new client tracker are handled on a per-namespace basis, so this upcall should be essentially ready for containerization. For now however, nfsd just starts it by calling the initialization and exit functions for init_net. I'm making the assumption that at some point in the future we'll be able to determine the net namespace from the nfs4_client. Until then, this patch hardcodes init_net in those places. I've sprinkled some "FIXME" comments around that code to attempt to make it clear where we'll need to fix that up later. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: J. Bruce Fields <bfields@redhat.com>

2012-03-26nfsd: add a per-net-namespace struct for nfsdJeff Layton
Eventually, we'll need this when nfsd gets containerized fully. For now, create a struct on a per-net-namespace basis that will just hold a pointer to the cld_net structure. That struct will hold all of the per-net data that we need for the cld tracker. Eventually we can add other pernet objects to struct nfsd_net.

2012-03-26nfsd: add nfsd4_client_tracking_ops struct and a way to set itJeff Layton
Abstract out the mechanism that we use to track clients into a set of client name tracking functions. This gives us a mechanism to plug in a new set of client tracking functions without disturbing the callers. It also gives us a way to decide on what tracking scheme to use at runtime. For now, this just looks like pointless abstraction, but later we'll add a new alternate scheme for tracking clients on stable storage. Note too that this patch anticipates the eventual containerization of this code by passing in struct net pointers in places. No attempt is made to containerize the legacy client tracker however.

2012-03-26nfsd: convert nfs4_client->cl_cb_flags to a generic flags fieldJeff Layton
We'll need a way to flag the nfs4_client as already being recorded on stable storage so that we don't continually upcall. Currently, that's recorded in the cl_firststate field of the client struct. Using an entire u32 to store a flag is rather wasteful though. The cl_cb_flags field is only using 2 bits right now, so repurpose that to a generic flags field. Rename NFSD4_CLIENT_KILL to NFSD4_CLIENT_CB_KILL to make it evident that it's part of the callback flags. Add a mask that we can use for existing checks that look to see whether any flags are set, so that the new flags don't interfere. Convert all references to cl_firstate to the NFSD4_CLIENT_STABLE flag, and add a new NFSD4_CLIENT_RECLAIM_COMPLETE flag. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: J.

2012-03-25Input: wacom - create inputs when wireless connectChris Bagwell
When a tablet connect or disconnect is detected, schedule work queue to register or unregister related input devices. When a wireless tablet connects, it reports same USB PID used if tablet is connected with USB cable. Use this to update features values, set input capabilities, and then register device. From there, the Pen and Touch interfaces will reuse the existing tablet's IRQ routines. Its possible that 1 receiver is shared with 2 tablets with different PID (small and medium Bamboo for example) so the input is unregister at disconnect to better support this case.

2012-03-25Input: wacom - wireless monitor frameworkChris Bagwell
The 3rd gen Bamboo Pen & Touch and Intuos5 tablets support an optional wireless module. When its receiver is plugged into USB, it presents 3 interfaces: 0) Monitor 1) Pen and 2) Touch. The exact capabilities of the Pen and Touch interfaces can not be determined until a tablet connection is established and reported over the Monitor interface. This patch detects this wireless receiver and enables interrupt packets to be processed for the Monitor interface. Processing the data in packets will be left to another patch. Since it doesn't make sense to create an input device for the Monitor interface, it is not created. Creation of Pen and Touch input device is also delayed until monitor packets can be processed.

2012-03-26dma-buf: add support for kernel cpu accessDaniel Vetter
Big differences to other contenders in the field (like ion) is that this also supports highmem, so we have to split up the cpu access from the kernel side into a prepare and a kmap step. Prepare is allowed to fail and should do everything required so that the kmap calls can succeed (like swapin/backing storage allocation, flushing, ...). More in-depth explanations will follow in the follow-up documentation patch. Changes in v2: - Clear up begin_cpu_access confusion noticed by Sumit Semwal. - Don't automatically fallback from the _atomic variants to the non-atomic variants. The _atomic callbacks are not allowed to sleep, so we want exporters to make this decision explicit. The function signatures are explicit, so simpler exporters can still use the same function for both. - Make the unmap functions optional. Simpler exporters with permanent mappings don't need to do anything at unmap time. Changes in v3: - Adjust the WARN_ON checks for the new ->ops functions as suggested by Rob Clark and Sumit Semwal. - Rebased on top of latest dma-buf-next git.

2012-03-26dma-buf: don't hold the mutex around map/unmap callsDaniel Vetter
The mutex protects the attachment list and hence needs to be held around the callbakc to the exporters (optional) attach/detach functions. Holding the mutex around the map/unmap calls doesn't protect any dma_buf state. Exporters need to properly protect any of their own state anyway (to protect against calls from their own interfaces). So this only makes the locking messier (and lockdep easier to anger). Therefore let's just drop this. v2: Rebased on top of latest dma-buf-next git.
