2013-02-21IB/core: Add "type 2" memory windows supportShani Michaeli
This patch enhances the IB core support for Memory Windows (MWs). MWs allow an application to have better/flexible control over remote access to memory. Two types of MWs are supported, with the second type having two flavors: Type 1 - associated with PD only Type 2A - associated with QPN only Type 2B - associated with PD and QPN Applications can allocate a MW once, and then repeatedly bind the MW to different ranges in MRs that are associated to the same PD. Type 1 windows are bound through a verb, while type 2 windows are bound by posting a work request. The 32-bit memory key is composed of a 24-bit index and an 8-bit key. The key is changed with each bind, thus allowing more control over the peer's use of the memory key. The changes introduced are the following: * add memory window type enum and a corresponding parameter to ib_alloc_mw. * type 2 memory window bind work request support. * create a struct that contains the common part of the bind verb struct ibv_mw_bind and the bind work request into a single struct. * add the ib_inc_rkey helper function to advance the tag part of an rkey. Consumer interface details: * new device capability flags IB_DEVICE_MEM_WINDOW_TYPE_2A and IB_DEVICE_MEM_WINDOW_TYPE_2B are added to indicate device support for these features. Devices can set either IB_DEVICE_MEM_WINDOW_TYPE_2A or IB_DEVICE_MEM_WINDOW_TYPE_2B if it supports type 2A or type 2B memory windows. It can set neither to indicate it doesn't support type 2 windows at all. * modify existing provides and consumers code to the new param of ib_alloc_mw and the ib_mw_bind_info structure Signed-off-by: Haggai Eran <haggaie@mellanox.com> Signed-off-by: Shani Michaeli <shanim@mellanox.com> Signed-off-by: Or Gerlitz <ogerlitz@mellanox.com> Signed-off-by: Roland Dreier <roland@purestorage.com>

For the iwlwifi pull, Johannes says: "I hadn't expected to ask you to pull iwlwifi-next again, but I have a number of fixes most of which I'd also send in after rc1, so here it is. The first commit is a merge error between mac80211-next and iwlwifi-next; in addition I have fixes for P2P scanning and MVM driver MAC (virtual interface) management from Ilan, a CT-kill (critical temperature) fix from Eytan, and myself fixed three different little but annoying bugs in the MVM driver. The only ones I might not send for -rc1 are Emmanuel's debug patch, but OTOH it should help greatly if there are any issues, and my own time event debugging patch that I used to find the race condition but we decided to keep it for the future." For the mac80211 pull, Johannes says: "Like iwlwifi-next, this would almost be suitable for rc1. I have a fix for station management on non-TDLS drivers, a CAB queue crash fix for mesh, a fix for an annoying (but harmless) warning, a tracing fix and a documentation fix. Other than that, only a few mesh cleanups." Along with that is a fix for memory corruption in rtlwifi, an orinoco_usb fix to avoid allocating a DMA buffer on the stack, an a hostap fix to return -ENOMEM instead of -1 after a memory allocation failure. The remaining bits implement 802.11ac support for the mwifiex driver -- I think that is still worth getting into 3.9.

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next John W. Linville says: ==================== This probably is the last big pull request for wireless bits for 3.9. Of course, I'm sure there will be a few stragglers here and there...surely a few bug fixes as well... :-) (In fact, I see that Johannes has already queued-up a few more for me while I was preparing this...) Included are a number of pulls... For mac80211-next, Johannes says: "The biggest change I have is undoubtedly Marco's mesh powersave implementation. Beyond that, I have a patch from Emmanuel to modify the DTIM period API in mac80211, scan improvements and a removal of some previous workaround code from Stanislaw, dynamic short slot time from Thomas and 64-bit station byte counters from Vladimir. I also made a number of changes myself, some related to WoWLAN, some auth/deauth improvements and most of them BSS list cleanups." "This time, I have relatively large number of fixes in various areas of the code (a memory leak in regulatory, an RX race in mac80211, the new radar checking caused a P2P device problem, some mesh issues with stations, an older bug in tracing and for kernel-doc) as well as a number of small new features. The biggest (in the diffstat) is my work on hidden SSID tracking." "Please pull to get * radar detection work from Simon * mesh improvements from Thomas * a connection monitoring/powersave fix from Wojciech * TDLS-related station management work from Jouni * VLAN crypto fixes from Michael Braun * CCK support in minstrel_ht from Felix * an SMPS (not SMSP, oops) related improvement in mac80211 (Emmanuel) * some WoWLAN work from Amitkumar Karwar: pattern match offset and a documentation fix * some WoWLAN work from myself (TCP connection wakeup feature API) * and a lot of VHT (and some HT) work (also from myself) And a number of more random cleanups/fixes. I merged mac80211/master to avoid a merge problem there." And regarding iwlwifi-next, Johannes says: "We continue work on our new driver, but I also have a WoWLAN and AP mode improvement for the previous driver and a change to use threaded interrupts to prepare us for working with non-PCIe devices." Regarding wl12xx, Luca says: "A few more patches intended for 3.9. Mostly some clean-ups I've been doing to make it easier to support device-tree. Also including one bug fix for wl12xx where the rates we advertise were wrong and an update in the wlconf structure to support newer firmwares." For the nfc-next bits, Samuel says: "This is the second NFC pull request for 3.9. We have: - A few pn533 fixes on top of Waldemar refactorization of the driver, one of them fixes target mode. - A new driver for Inside Secure microread chipset. It supports two physical layers: i2c and MEI. The MEI one depends on a patchset that's been sent to Greg Kroah-Hartman for inclusion into the 3.9 kernel [1]. The dependency is a KConfig one which means this code is not buildable as long as the MEI API is not usptream." "This 3rd NFC pull request for 3.9 contains a fix for the microread MEI physical layer support, as the MEI bus API changed. From the MEI code, we now pass the MEI id back to the driver probe routine, and we also pass a name and a MEI id table through the mei_bus_driver structure. A few renames as well like e.g. mei_bus_driver to mei_driver or mei_bus_client to mei_device in order to be closer to the driver model practices." For the ath6kl bits, Kalle says: "There's not anything special here, most of the patches are just code cleanup. The only functional changes are using the beacon interval from user space and fixing a crash which happens when inserting and removing the module in a loop." Also, I pulled the wireless tree in order to resolve some pending merge issues. On top of that, there is a bunch of work on brcmfmac that leads up to P2P support. Also, mwifiex, rtlwifi, and a variety of other drivers see some basic cleanups and minor enhancements. Please let me know if there are problems! ==================== Signed-off-by: David S.

2013-02-18libceph: kill ceph_osdc_wait_event()Alex Elder
There are no actual users of ceph_osdc_wait_event(). This would have been one-shot events, but we no longer support those so just get rid of this function. Since this leaves nothing else that waits for the completion of an event, we can get rid of the completion in a struct ceph_osd_event.

2013-02-18libceph: kill ceph_osdc_create_event() "one_shot" parameterAlex Elder
There is only one caller of ceph_osdc_create_event(), and it provides 0 as its "one_shot" argument. Get rid of that argument and just use 0 in its place. Replace the code in handle_watch_notify() that executes if one_shot is nonzero in the event with a BUG_ON() call. While modifying "osd_client.c", give handle_watch_notify() static scope.

2013-02-18libceph: kill ceph_calc_raw_layout()Alex Elder
There is no caller of ceph_calc_raw_layout() outside of libceph, so there's no need to export from the module. Furthermore, there is only one caller, in calc_layout(), and it is not much more than a simple wrapper for that function. So get rid of ceph_calc_raw_layout() and embed it instead within calc_layout(). While touching "osd_client.c", get rid of the unnecessary forward declaration of __send_request().

2013-02-18libdeph: don't export ceph_osdc_init() or ceph_osdc_stop()Alex Elder
The only callers of ceph_osdc_init() and ceph_osdc_stop() ceph_create_client() and ceph_destroy_client() (respectively) and they are in the same kernel module as those two functions. There's therefore no need to export those interfaces, so don't. Signed-off-by: Alex Elder <elder@inktank.com> Reviewed-by: Josh Durgin <josh.durgin@inktank.com>
2013-02-18libceph: lock outside send_queued()Alex Elder
Two of the three callers of the osd client's send_queued() function already hold the osd client mutex and drop it before the call. Change send_queued() so it assumes the caller holds the mutex, and update all callers accordingly. Rename it __send_queued() to match the convention used elsewhere in the file with respect to the lock. Signed-off-by: Alex Elder <elder@inktank.com> Reviewed-by: Josh Durgin <josh.durgin@inktank.com>
2013-02-18ceph: kill ceph_osdc_new_request() "num_reply" parameterAlex Elder
The "num_reply" parameter to ceph_osdc_new_request() is never used inside that function, so get rid of it. Note that ceph_sync_write() passes 2 for that argument, while all other callers pass 1. It doesn't matter, but perhaps someone should verify this doesn't indicate a problem. Signed-off-by: Alex Elder <elder@inktank.com> Reviewed-by: Josh Durgin <josh.durgin@inktank.com>

2013-02-18cfg80211: fix station change if TDLS isn't supportedJohannes Berg
Larry noticed (and bisected) that commit df881293c6ba9a12868491a717b25 "cfg80211: Pass TDLS peer's QoS/HT/VHT information during set_station" broke secure connections. This is is the case only for drivers that don't support TDLS, where any kind of change, even just the change of authorized flag that is required for normal operation, was rejected now. To fix this, remove the checks. I have some patches that will add proper verification for all the different cases later.
