2013-06-26linux/const.h: Add _BITUL() and _BITULL()H. Peter Anvin1-0/+3
Add macros for single bit definitions of a specific type. These are similar to the BIT() macro that already exists, but with a few exceptions: 1. The namespace is such that they can be used in uapi definitions. 2. The type is set with the _AC() macro to allow it to be used in assembly. 3. The type is explicitly specified to be UL or ULL.

2013-06-21vfio: hugepage support for vfio_iommu_type1Alex Williamson1-2/+6
We currently send all mappings to the iommu in PAGE_SIZE chunks, which prevents the iommu from enabling support for larger page sizes. We still need to pin pages, which means we step through them in PAGE_SIZE chunks, but we can batch up contiguous physical memory chunks to allow the iommu the opportunity to use larger pages. The approach here is a bit different that the one currently used for legacy KVM device assignment. Rather than looking at the vma page size and using that as the maximum size to pass to the iommu, we instead simply look at whether the next page is physically contiguous. This means we might ask the iommu to map a 4MB region, while legacy KVM might limit itself to a maximum of 2MB. Splitting our mapping path also allows us to be smarter about locked memory because we can more easily unwind if the user attempts to exceed the limit. Therefore, rather than assuming that a mapping will result in locked memory, we test each page as it is pinned to determine whether it locks RAM vs an mmap'd MMIO region. This should result in better locking granularity and less locked page fudge factors in userspace. The unmap path uses the same algorithm as legacy KVM. We don't want to track the pfn for each mapping ourselves, but we need the pfn in order to unpin pages. We therefore ask the iommu for the iova to physical address translation, ask it to unpin a page, and see how many pages were actually unpinned. iommus supporting large pages will often return something bigger than a page here, which we know will be physically contiguous and we can unpin a batch of pfns. iommus not supporting large mappings won't see an improvement in batching here as they only unmap a page at a time. With this change, we also make a clarification to the API for mapping and unmapping DMA. We can only guarantee unmaps at the same granularity as used for the original mapping. In other words, unmapping a subregion of a previous mapping is not guaranteed and may result in a larger or smaller unmapping than requested. The size field in the unmapping structure is updated to reflect this. Previously this was unmodified on mapping, always returning the the requested unmap size. This is now updated to return the actual unmap size on success, allowing userspace to appropriately track mappings. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>

2013-06-20powerpc/vfio: Implement IOMMU driver for VFIOAlexey Kardashevskiy1-0/+34
VFIO implements platform independent stuff such as a PCI driver, BAR access (via read/write on a file descriptor or direct mapping when possible) and IRQ signaling. The platform dependent part includes IOMMU initialization and handling. This implements an IOMMU driver for VFIO which does mapping/unmapping pages for the guest IO and provides information about DMA window (required by a POWER guest).

2013-06-20tcp: introduce a per-route knob for quick ackCong Wang1-0/+2
In previous discussions, I tried to find some reasonable heuristics for delayed ACK, however this seems not possible, according to Eric: "ACKS might also be delayed because of bidirectional traffic, and is more controlled by the application response time. TCP stack can not easily estimate it." "ACK can be incredibly useful to recover from losses in a short time. The vast majority of TCP sessions are small lived, and we send one ACK per received segment anyway at beginning or retransmits to let the sender smoothly increase its cwnd, so an auto-tuning facility wont help them that much." and according to David: "ACKs are the only information we have to detect loss. And, for the same reasons that TCP VEGAS is fundamentally broken, we cannot measure the pipe or some other receiver-side-visible piece of information to determine when it's "safe" to stretch ACK. And even if it's "safe", we should not do it so that losses are accurately detected and we don't spuriously retransmit. The only way to know when the bandwidth increases is to "test" it, by sending more and more packets until drops happen. That's why all successful congestion control algorithms must operate on explicited tested pieces of information. Similarly, it's not really possible to universally know if it's safe to stretch ACK or not." It still makes sense to enable or disable quick ack mode like what TCP_QUICK_ACK does. Similar to TCP_QUICK_ACK option, but for people who can't modify the source code and still wants to control TCP delayed ACK behavior. As David suggested, this should belong to per-path scope, since different pathes may want different behaviors.

Conflicts: drivers/net/wireless/ath/ath9k/Kconfig drivers/net/xen-netback/netback.c net/batman-adv/bat_iv_ogm.c net/wireless/nl80211.c The ath9k Kconfig conflict was a change of a Kconfig option name right next to the deletion of another option. The xen-netback conflict was overlapping changes involving the handling of the notify list in xen_netbk_rx_action(). Batman conflict resolution provided by Antonio Quartulli, basically keep everything in both conflict hunks. The nl80211 conflict is a little more involved. In 'net' we added a dynamic memory allocation to nl80211_dump_wiphy() to fix a race that Linus reported. Meanwhile in 'net-next' the handlers were converted to use pre and post doit handlers which use a flag to determine whether to hold the RTNL mutex around the operation. However, the dump handlers to not use this logic. Instead they have to explicitly do the locking. There were apparent bugs in the conversion of nl80211_dump_wiphy() in that we were not dropping the RTNL mutex in all the return paths, and it seems we very much should be doing so. So I fixed that whilst handling the overlapping changes. To simplify the initial returns, I take the RTNL mutex after we try to allocate 'tb'. Signed-off-by: David S. Miller <davem@davemloft.net>

2013-06-14NFC: Add firmware upload netlink commandEric Lapuyade1-0/+6
As several NFC chipsets can have their firmwares upgraded and reflashed, this patchset adds a new netlink command to trigger that the driver loads or flashes a new firmware. This will allows userspace triggered firmware upgrade through netlink. The firmware name or hint is passed as a parameter, and the driver will eventually fetch the firmware binary through the request_firmware API. The cmd can only be executed when the nfc dev is not in use. Actual firmware loading/flashing is an asynchronous operation. Result of the operation shall send a new event up to user space through the nfc dev multicast socket. During operation, the nfc dev is not openable and thus not usable.

2013-05-25cfg80211: Allow TDLS peer AID to be configured for VHTJouni Malinen1-0/+7
VHT uses peer AID in the PARTIAL_AID field in TDLS frames. The current design for TDLS is to first add a dummy STA entry before completing TDLS Setup and then update information on this STA entry based on what was received from the peer during the setup exchange. In theory, this could use NL80211_ATTR_STA_AID to set the peer AID just like this is used in AP mode to set the AID of an association station. However, existing cfg80211 validation rules prevent this attribute from being used with set_station operation. To avoid interoperability issues between different kernel and user space version combinations, introduce a new nl80211 attribute for the purpose of setting TDLS peer AID. This attribute can be used in both the new_station and set_station operations. It is not supposed to be allowed to change the AID value during the lifetime of the STA entry, but that validation is left for drivers to do in the change_station callback.

2013-05-20virtio_pci: better macro exported in uapiMichael S. Tsirkin1-1/+3
Macro VIRTIO_PCI_CONFIG assumes that userspace actually has a structure with a field named msix_enabled. Add VIRTIO_PCI_CONFIG_OFF that gets the msix_enabled by value instead, to make it useful for userspace. We still keep VIRTIO_PCI_CONFIG around for now, in case some userspace uses it.
