Zoltan Kiss says: ==================== xen-netback: Changes around carrier handling This series starts using carrier off as a way to purge packets when the guest is not able (or willing) to receive them. It is a much faster way to get rid of packets waiting for an overwhelmed guest. The first patch changes current netback code where it relies currently on netif_carrier_ok. The second turns off the carrier if the guest times out on a queue, and only turn it on again if that queue (or queues) resurrects. ==================== Signed-off-by:

Currently when the guest is not able to receive more packets, qdisc layer starts a timer, and when it goes off, qdisc is started again to deliver a packet again. This is a very slow way to drain the queues, consumes unnecessary resources and slows down other guests shutdown. This patch change the behaviour by turning the carrier off when that timer fires, so all the packets are freed up which were stucked waiting for that vif. Instead of the rx_queue_purge bool it uses the VIF_STATUS_RX_PURGE_EVENT bit to signal the thread that either the timeout happened or an RX interrupt arrived, so the thread can check what it should do. It also disables NAPI, so the guest can't transmit, but leaves the interrupts on, so it can resurrect. Only the queues which brought down the interface can enable it again, the bit QUEUE_STATUS_RX_STALLED makes sure of that. Signed-off-by:

This patch introduces a new state bit VIF_STATUS_CONNECTED to track whether the vif is in a connected state. Using carrier will not work with the next patch in this series, which aims to turn the carrier temporarily off if the guest doesn't seem to be able to receive packets. Signed-off-by:

Merge tag 'master-2014-07-31' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next Conflicts: net/6lowpan/iphc.c Minor conflicts in iphc.c were changes overlapping with some style cleanups. John W. Linville says: ==================== Please pull this last(?) batch of wireless change intended for the 3.17 stream... For the NFC bits, Samuel says: "This is a rather quiet one, we have: - A new driver from ST Microelectronics for their NCI ST21NFCB, including device tree support. - p2p support for the ST21NFCA driver - A few fixes an enhancements for the NFC digital laye" For the Atheros bits, Kalle says: "Michal and Janusz did some important RX aggregation fixes, basically we were missing RX reordering altogether. The 10.1 firmware doesn't support Ad-Hoc mode and Michal fixed ath10k so that it doesn't advertise Ad-Hoc support with that firmware. Also he implemented a workaround for a KVM issue." For the Bluetooth bits, Gustavo and Johan say: "To quote Gustavo from his previous request: 'Some last minute fixes for -next. We have a fix for a use after free in RFCOMM, another fix to an issue with ADV_DIRECT_IND and one for ADV_IND with auto-connection handling. Last, we added support for reading the codec and MWS setting for controllers that support these features.' Additionally there are fixes to LE scanning, an update to conform to the 4.1 core specification as well as fixes for tracking the page scan state. All of these fixes are important for 3.17." And, "We've got: - 6lowpan fixes/cleanups - A couple crash fixes, one for the Marvell HCI driver and another in LE SMP. - Fix for an incorrect connected state check - Fix for the bondable requirement during pairing (an issue which had crept in because of using "pairable" when in fact the actual meaning was "bondable" (these have different meanings in Bluetooth)" Along with those are some late-breaking hardware support patches in brcmfmac and b43 as well as a stray ath9k patch. ==================== Signed-off-by:

Intel did some benchmarking on our network throughput when Linux on Hyper-V is as used as a gateway. This fix gave us almost a 1 Gbps additional throughput on about 5Gbps base throughput we hadi, prior to increasing the sendbuf size. The sendbuf mechanism is a copy based transport that we have which is clearly more optimal than the copy-free page flipping mechanism (for small packets). In the forwarding scenario, we deal only with MTU sized packets, and increasing the size of the senbuf area gave us the additional performance. For what it is worth, Windows guests on Hyper-V, I am told use similar sendbuf size as well. The exact value of sendbuf I think is less important than the fact that it needs to be larger than what Linux can allocate as physically contiguous memory. Thus the change over to allocating via vmalloc(). We currently allocate 16MB receive buffer and we use vmalloc there for allocation. Also the low level channel code has already been modified to deal with physically dis-contiguous memory in the ringbuffer setup. Based on experimentation Intel did, they say there was some improvement in throughput as the sendbuf size was increased up to 16MB and there was no effect on throughput beyond 16MB. Thus I have chosen 16MB here. Increasing the sendbuf value makes a material difference in small packet handling In this version of the patch, based on David's feedback, I have added additional details in the commit log.

Thomas Graf says: ==================== Lockless netlink_lookup() with new concurrent hash table Netlink sockets are maintained in a hash table to allow efficient lookup via the port ID for unicast messages. However, lookups currently require a read lock to be taken. This series adds a new generic, resizable, scalable, concurrent hash table based on the paper referenced in the first patch. It then makes use of the new data type to implement lockless netlink_lookup(). Patch 3/3 to convert nft_hash is included for reference but should be merged via the netfilter tree. Inclusion in this series is to provide context for the suggested API. Against net-next since the initial user of the new hash table is in net/ Changes: v4-v5: - use GFP_KERNEL to alloc Netlink buckets as suggested by Nikolay Aleksandrov - free nft hash element on removal as spotted by Nikolay Aleksandrov and Patrick McHardy v3-v4: - fixed wrong shift assignment placement as spotted by Nikolay Aleksandrov - reverted default size of nft_hash to 4 as requested by Patrick McHardy, default size for other hash tables remains at 64 if no hint is given - fixed copyright as requested by Patrick McHardy v2-v3: - fixed typo in nft_hash_destroy() when passing rhashtable handle v1-v2: - fixed traversal off-by-one as spotted by Tobias Klauser - removed unlikely() from BUG_ON() as spotted by Josh Triplett - new 3rd patch to convert nft_hash to rhashtable - make rhashtable_insert() return void - nl_sk_hash_lock must be a mutex - fixed wrong name of rht_shrink_below_30() - exported symbols rht_grow_above_75() and rht_shrink_below_30() - allow table freeing with RCU callback ==================== Signed-off-by: -

Heavy Netlink users such as Open vSwitch spend a considerable amount of time in netlink_lookup() due to the read-lock on nl_table_lock. Use of RCU relieves the lock contention. Makes use of the new resizable hash table to avoid locking on the lookup. The hash table will grow if entries exceeds 75% of table size up to a total table size of 64K. It will automatically shrink if usage falls below 30%. Also splits nl_table_lock into a separate mutex to protect hash table mutations and allow synchronize_rcu() to sleep while waiting for readers during expansion and shrinking.

Generic implementation of a resizable, scalable, concurrent hash table based on [0]. The implementation supports both, fixed size keys specified via an offset and length, or arbitrary keys via own hash and compare functions. Lookups are lockless and protected as RCU read side critical sections. Automatic growing/shrinking based on user configurable watermarks is available while allowing concurrent lookups to take place. Objects to be hashed must include a struct rhash_head. The reason for not using the existing struct hlist_head is that the expansion and shrinking will have two buckets point to a single entry which would lead in obscure reverse chaining behaviour. Code includes a boot selftest if CONFIG_TEST_RHASHTABLE is defined. [0] https://www.usenix.org/legacy/event/atc11/tech/final_files/Triplett.pdfSigned-off-by:

Aaron Brown says: ==================== Intel Wired LAN Driver Updates This series contains updates to the i40e and i40evf drivers. Vasu adds FCOE support, build options and a documentation pointer to i40e. Shannon exposes a Firmware API request used to do register writes on the driver's behalf and disables local loopback on VMDQ VSI in order to stop the VEB from echoing the VMDQ packets back at the VSI. Ashish corrects the vf_id offset for virtchnl messages in the case of multiple PFs, removes support for vf unicast promiscuos mode to disallow VFs from receiving traffic intended for another VF, updates the vfr_stat state check to handle the existing and future mechanism and adds an adapter state check to prevent re-arming the watchdog timer after i40evf_remove has been called and the timer has been deleted. Serey fixes an issue where a guest OS would panic when removing the vf driver while the device is being reset due to an attempt to clean a non initialized mac_filter_list. Akeem makes a minor comment change. Jessie changes an instance of sprintf to snprintf that was missed when the driver was converted to use snprintf everywhere.

If the driver is loaded and then unloaded before the interface is brought up, then it will allocate a MAC filter entry and never free it. To fix this, on unload, run through the mac filter list and free all the entries. We also do this during reset recovery when the driver cannot contact the PF and needs to shut down completely.
