2014-12-11net/mlx4: Add A0 hybrid steeringMatan Barak7-23/+292
A0 hybrid steering is a form of high performance flow steering. By using this mode, mlx4 cards use a fast limited table based steering, in order to enable fast steering of unicast packets to a QP. In order to implement A0 hybrid steering we allocate resources from different zones: (1) General range (2) Special MAC-assigned QPs [RSS, Raw-Ethernet] each has its own region. When we create a rss QP or a raw ethernet (A0 steerable and BF ready) QP, we try hard to allocate the QP from range (2). Otherwise, we try hard not to allocate from this range. However, when the system is pushed to its limits and one needs every resource, the allocator uses every region it can. Meaning, when we run out of raw-eth qps, the allocator allocates from the general range (and the special-A0 area is no longer active). If we run out of RSS qps, the mechanism tries to allocate from the raw-eth QP zone. If that is also exhausted, the allocator will allocate from the general range (and the A0 region is no longer active). Note that if a raw-eth qp is allocated from the general range, it attempts to allocate the range such that bits 6 and 7 (blueflame bits) in the QP number are not set. When the feature is used in SRIOV, the VF has to notify the PF what kind of QP attributes it needs. In order to do that, along with the "Eth QP blueflame" bit, we reserve a new "A0 steerable QP". According to the combination of these bits, the PF tries to allocate a suitable QP. In order to maintain backward compatibility (with older PFs), the PF notifies which QP attributes it supports via QUERY_FUNC_CAP command.

2014-12-11net/mlx4: Add mlx4_bitmap zone allocatorMatan Barak2-0/+451
The zone allocator is a mechanism which manages a few mlx4_bitmaps. When allocating a resource, the user indicates the desired zone of which this resource will be allocated from. If possible, the resource will be allocated from this zone. Otherwise, the resource will be allocated from a less-than, equal-to, higher-than priority zone, according to the desired zone's properties with that respective allocation order.

2014-12-11net/mlx4: Add a check if there are too many reserved QPsDotan Barak1-1/+7

2014-12-11net/mlx4: Change QP allocation schemeEugenia Emantayev13-36/+118
When using BF (Blue-Flame), the QPN overrides the VLAN, CV, and SV fields in the WQE. Thus, BF may only be used for QPNs with bits 6,7 unset. The current Ethernet driver code reserves a Tx QP range with 256b alignment. This is wrong because if there are more than 64 Tx QPs in use, QPNs >= base + 65 will have bits 6/7 set. This problem is not specific for the Ethernet driver, any entity that tries to reserve more than 64 BF-enabled QPs should fail. Also, using ranges is not necessary here and is wasteful. The new mechanism introduced here will support reservation for "Eth QPs eligible for BF" for all drivers: bare-metal, multi-PF, and VFs (when hypervisors support WC in VMs). The flow we use is: 1. In mlx4_en, allocate Tx QPs one by one instead of a range allocation, and request "BF enabled QPs" if BF is supported for the function 2. In the ALLOC_RES FW command, change param1 to: a. param1[23:0] - number of QPs b. param1[31-24] - flags controlling QPs reservation Bit 31 refers to Eth blueflame supported QPs. Those QPs must have bits 6 and 7 unset in order to be used in Ethernet. Bits 24-30 of the flags are currently reserved. When a function tries to allocate a QP, it states the required attributes for this QP. Those attributes are considered "best-effort". If an attribute, such as Ethernet BF enabled QP, is a must-have attribute, the function has to check that attribute is supported before trying to do the allocation. In a lower layer of the code, mlx4_qp_reserve_range masks out the bits which are unsupported. If SRIOV is used, the PF validates those attributes and masks out unsupported attributes as well. In order to notify VFs which attributes are supported, the VF uses QUERY_FUNC_CAP command. This command's mailbox is filled by the PF, which notifies which QP allocation attributes it supports.

2014-12-11net/mlx4_core: Use tasklet for user-space CQ completion eventsMatan Barak4-2/+81
Previously, we've fired all our completion callbacks straight from our ISR. Some of those callbacks were lightweight (for example, mlx4_en's and IPoIB napi callbacks), but some of them did more work (for example, the user-space RDMA stack uverbs' completion handler). Besides that, doing more than the minimal work in ISR is generally considered wrong, it could even lead to a hard lockup of the system. Since when a lot of completion events are generated by the hardware, the loop over those events could be so long, that we'll get into a hard lockup by the system watchdog. In order to avoid that, add a new way of invoking completion events callbacks. In the interrupt itself, we add the CQs which receive completion event to a per-EQ list and schedule a tasklet. In the tasklet context we loop over all the CQs in the list and invoke the user callback.

The encapsulated offload flags shouldn't be unconditionally exported to the stack. The stack expects offloading to work across all tunnel types when those flags are set. This would break other tunnels (like GRE) since be2net currently supports tunnel offload for VxLAN only. Also, with VxLANs Skyhawk-R can offload only 1 UDP dport. If more than 1 UDP port is added, we should disable offloads in that case too.

Hook a ndo_set_mac_address callback, update the internal Ethernet MAC in the netdevice structure, and finally write that address down to the UniMAC registers. If the interface is down, and most likely clock gated, we do not update the registers but just the local copy, such that next ndo_open() call will effectively write down the address.

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next John W. Linville says: ==================== pull request: wireless-next 2014-12-08 Please pull this last batch of pending wireless updates for the 3.19 tree... For the wireless bits, Johannes says: "This time I have Felix's no-status rate control work, which will allow drivers to work better with rate control even if they don't have perfect status reporting. In addition to this, a small hwsim fix from Patrik, one of the regulatory patches from Arik, and a number of cleanups and fixes I did myself. Of note is a patch where I disable CFG80211_WEXT so that compatibility is no longer selectable - this is intended as a wake-up call for anyone who's still using it, and is still easily worked around (it's a one-line patch) before we fully remove the code as well in the future." For the Bluetooth bits, Johan says: "Here's one more bluetooth-next pull request for 3.19: - Minor cleanups for ieee802154 & mac802154 - Fix for the kernel warning with !TASK_RUNNING reported by Kirill A. Shutemov - Support for another ath3k device - Fix for tracking link key based security level - Device tree bindings for btmrvl + a state update fix - Fix for wrong ACL flags on LE links" And... "In addition to the previous one this contains two more cleanups to mac802154 as well as support for some new HCI features from the Bluetooth 4.2 specification. From the original request: 'Here's what should be the last bluetooth-next pull request for 3.19. It's rather large but the majority of it is the Low Energy Secure Connections feature that's part of the Bluetooth 4.2 specification. The specification went public only this week so we couldn't publish the corresponding code before that. The code itself can nevertheless be considered fairly mature as it's been in development for over 6 months and gone through several interoperability test events. Besides LE SC the pull request contains an important fix for command complete events for mgmt sockets which also fixes some leaks of hci_conn objects when powering off or unplugging Bluetooth adapters. A smaller feature that's part of the pull request is service discovery support. This is like normal device discovery except that devices not matching specific UUIDs or strong enough RSSI are filtered out. Other changes that the pull request contains are firmware dump support to the btmrvl driver, firmware download support for Broadcom BCM20702A0 variants, as well as some coding style cleanups in 6lowpan & ieee802154/mac802154 code.'" For the NFC bits, Samuel says: "With this one we get: - NFC digital improvements for DEP support: Chaining, NACK and ATN support added. - NCI improvements: Support for p2p target, SE IO operand addition, SE operands extensions to support proprietary implementations, and a few fixes. - NFC HCI improvements: OPEN_PIPE and NOTIFY_ALL_CLEARED support, and SE IO operand addition. - A bunch of minor improvements and fixes for STMicro st21nfcb and st21nfca" For the iwlwifi bits, Emmanuel says: "Major works are CSA and TDLS. On top of that I have a new firmware API for scan and a few rate control improvements. Johannes find a few tricks to improve our CPU utilization and adds support for a new spin of 7265 called 7265D. Along with this a few random things that don't stand out." And... "I deprecate here -8.ucode since -9 has been published long ago. Along with that I have a new activity, we have now better a infrastructure for firmware debugging. This will allow to have configurable probes insides the firmware. Luca continues his work on NetDetect, this feature is now complete. All the rest is minor fixes here and there." For the Atheros bits, Kalle says: "Only ath10k changes this time and no major changes. Most visible are: o new debugfs interface for runtime firmware debugging (Yanbo) o fix shared WEP (Sujith) o don't rebuild whenever kernel version changes (Johannes) o lots of refactoring to make it easier to add new hw support (Michal) There's also smaller fixes and improvements with no point of listing here." In addition, there are a few last minute updates to ath5k, ath9k, brcmfmac, brcmsmac, mwifiex, rt2x00, rtlwifi, and wil6210. Also included is a pull of the wireless tree to pick-up the fixes originally included in "pull request: wireless 2014-12-03"...

Almost all of Shannon's patches cleanup/fix NVM issues varying in range from adding more detail to debug messages, to removing dead code, to fixing NVM state transitions after an error. Change the handy decoder interface for admin queue return code to help catch and properly report the condition as a useful errno rather than returning a misleading '0'. Added a range check to avoid any possible array index-out-of-bound issues. v2: - fixed up patch 05 in the series to use the ARRAY_SIZE() macro as suggested by Sergei Shtylyov - fix up patch 13 to remove unnecessary parens in the return statement as suggested by Sergei Shtylyov ==================== Signed-off-by: David S.

... making both non-draining. That means that tcp_recvmsg() becomes non-draining. And _that_ would break iscsit_do_rx_data() unless we a) make sure tcp_recvmsg() is uniformly non-draining (it is) b) make sure it copes with arbitrary (including shifted) iov_iter (it does, all it uses is iov_iter primitives) c) make iscsit_do_rx_data() initialize ->msg_iter only once. Fortunately, (c) is doable with minimal work and we are rid of one the two places where kernel send/recvmsg users would be unhappy with non-draining behaviour. Actually, that makes all but one of ->recvmsg() instances iov_iter-clean. The exception is skcipher_recvmsg() and it also isn't hard to convert to primitives (iov_iter_get_pages() is needed there). That'll wait a bit - there's some interplay with ->sendmsg() path for that one. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
