2015-07-04Merge tag 'ntb-4.2' of git://github.com/jonmason/ntbLinus Torvalds2-28/+34
Pull NTB updates from Jon Mason: "This includes a pretty significant reworking of the NTB core code, but has already produced some significant performance improvements. An abstraction layer was added to allow the hardware and clients to be easily added. This required rewriting the NTB transport layer for this abstraction layer. This modification will allow future "high performance" NTB clients. In addition to this change, a number of performance modifications were added. These changes include NUMA enablement, using CPU memcpy instead of asyncdma, and modification of NTB layer MTU size" * tag 'ntb-4.2' of git://github.com/jonmason/ntb: (22 commits) NTB: Add split BAR output for debugfs stats NTB: Change WARN_ON_ONCE to pr_warn_once on unsafe NTB: Print driver name and version in module init NTB: Increase transport MTU to 64k from 16k NTB: Rename Intel code names to platform names NTB: Default to CPU memcpy for performance NTB: Improve performance with write combining NTB: Use NUMA memory in Intel driver NTB: Use NUMA memory and DMA chan in transport NTB: Rate limit ntb_qp_link_work NTB: Add tool test client NTB: Add ping pong test client NTB: Add parameters for Intel SNB B2B addresses NTB: Reset transport QP link stats on down NTB: Do not advance transport RX on link down NTB: Differentiate transport link down messages NTB: Check the device ID to set errata flags NTB: Enable link for Intel root port mode in probe NTB: Read peer info from local SPAD in transport NTB: Split ntb_hw_intel and ntb_transport drivers ...

Pull virtio/vhost cross endian support from Michael Tsirkin: "I have just queued some more bugfix patches today but none fix regressions and none are related to these ones, so it looks like a good time for a merge for -rc1. The motivation for this is support for legacy BE guests on the new LE hosts. There are two redeeming properties that made me merge this: - It's a trivial amount of code: since we wrap host/guest accesses anyway, almost all of it is well hidden from drivers. - Sane platforms would never set flags like VHOST_CROSS_ENDIAN_LEGACY, and when it's clear, there's zero overhead (as some point it was tested by compiling with and without the patches, got the same stripped binary). Maybe we could create a Kconfig symbol to enforce the second point: prevent people from enabling it eg on x86.

2015-06-29amd-xgbe: Add the __GFP_NOWARN flag to Rx buffer allocationTom Lendacky1-1/+1
When allocating Rx related buffers, alloc_pages is called using an order number that is decreased until successful. A system under stress can experience failures during this allocation process resulting in a warning being issued. This message can be of concern to end users even though the failure is not fatal. Since the failure is not fatal and can occur multiple times, the driver should include the __GFP_NOWARN flag to suppress the warning message from being issued.

2015-06-28net: phy: mdio-bcm-unimac: workaround initial read failures for integrated PHYsFlorian Fainelli1-0/+43
All BCM7xxx integrated Gigabit PHYs have an issue in their MDIO management controller which will make the initial read or write to them to fail and return 0xffff. This is a real issue as the typical first thing we do is read from MII_PHYSID1 and MII_PHYSID2 from get_phy_id() to register a driver for these PHYs. Coupled with the workaround in drivers/net/phy/bcm7xxx.c, this workaround for the MDIO bus controller consists in scanning the list of PHYs to do this initial read workaround for as part of the MDIO bus reset routine which is invoked prior to mdiobus_scan(). Once we have a proper PHY driver/device registered, all workarounds are located there (e.g: power management suspend/resume calls).

2015-06-28bnx2x: fix DMA API usageMichal Schmidt3-24/+12
With CONFIG_DMA_API_DEBUG=y bnx2x triggers the error "DMA-API: device driver frees DMA memory with wrong function". On archs where PAGE_SIZE > SGE_PAGE_SIZE it also triggers "DMA-API: device driver frees DMA memory with different size". Fix this by making the mapping and unmapping symmetric: - Do not map the whole pool page at once. Instead map the SGE_PAGE_SIZE-sized pieces individually, so they can be unmapped in the same manner. - What's mapped using dma_map_page() must be unmapped using dma_unmap_page(). Tested on ppc64.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-queue Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-06-26 This series contains fixes for igb, e1000e and i40evf. Todd disables IPv6 extension header processing due to a hardware errata and bumps the driver version. Yanir provides six fixes for e1000e. First is a fix for a locking issue where we were not always taking the pci_bus_sem semaphore all the time when calling pci_disable_link_state_locked(), so fix the code to only call pci_disable_link_state_locked() when the semaphore has been acquired, otherwise call pci_disable_link_state(). A previous fix for i219 where the hardware prevented ULP entry caused EEE in Sx not the be enabled, so modify the code flow that allows both ULP and EEE in Sx. Fix an issue when running 10/100 full duplex on i219 where CRC errors were occurring by increasing the IPG from 8 to 0xC as per the hardware developers. Fix a data corruption issue found on some platforms by increasing the minimum gap between the PHY FIFO read and write pointers. Fix i219, which does not require the K1 workaround for LPT devices. Mitch provides a i40evf fix for a panic when changing MTU. Down was requesting queue disables, but then exited immediately without waiting for the queues to actually be disabled. This could allow any function called after i40evf_down() to run immediately, including i40evf_up(), and causes a memory leak. Fixed the issue by removing the whole reinit_locked function which allows for the driver to handle the state changes by requesting reset from the periodic timer. The second fix resolves an issue where RSS was being configured as though it is using the maximum number of queue. This can cause the device to drop a lot of receive traffic, as the packets get assigned to non-functional queues. This is resolved by only configuring RSS with the number of active queues. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2015-06-28net: fec: don't access RACC register when not availableGreg Ungerer2-13/+19
Not all silicon implementations of the Freescale FEC hardware module have the RACC (Receive Accelerator Function) register, so we should not be trying to access it on those that don't. Currently none of the ColdFire based parts with a FEC have it. Support for RACC was introduced by commit 4c09eed9 ("net: fec: Enable imx6 enet checksum acceleration"). A fix was introduced in commit d1391930 ("net: fec: Fix build for MCF5272") that disables its use on the ColdFire M5272 part, but it doesn't fix the general case of other ColdFire parts. To fix we create a quirk flag, FEC_QUIRK_HAS_RACC, and check it before working with the RACC register. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Signed-off-by: David S.

When limiting phy link speed using "max-speed" to 100mbps or less on a giga bit phy, phy never completes auto negotiation and phy state machine is held in PHY_AN. Fixing this issue by comparing the giga bit advertise though phydev->supported doesn't have it but phy has BMSR_ESTATEN set. So that auto negotiation is restarted as old and new advertise are different and link comes up fine.

This could allow any function called after i40evf_down to run immediately, including i40evf_up, and causes a memory leak. Removing the whole reinit_locked function is the best way to go about this, and allows for the driver to handle the state changes by requesting reset from the periodic timer.

2015-06-25netconsole: implement extended console supportTejun Heo1-2/+139
printk logbuf keeps various metadata and optional key=value dictionary for structured messages, both of which are stripped when messages are handed to regular console drivers. It can be useful to have this metadata and dictionary available to netconsole consumers. This obviously makes logging via netconsole more complete and the sequence number in particular is useful in environments where messages may be lost or reordered in transit - e.g. when netconsole is used to collect messages in a large cluster where packets may have to travel congested hops to reach the aggregator. The lost and reordered messages can easily be identified and handled accordingly using the sequence numbers. printk recently added extended console support which can be selected by setting CON_EXTENDED flag. From console driver side, not much changes. The only difference is that the text passed to the write callback is formatted the same way as /dev/kmsg. This patch implements extended console support for netconsole which can be enabled by either prepending "+" to a netconsole boot param entry or echoing 1 to "extended" file in configfs. When enabled, netconsole transmits extended log messages with headers identical to /dev/kmsg output. There's one complication due to message fragments. netconsole limits the maximum message size to 1k and messages longer than that are split into multiple fragments. As all extended console messages should carry matching headers and be uniquely identifiable, each extended message fragment carries full copy of the metadata and an extra header field to identify the specific fragment. The optional header is of the form "ncfrag=OFF/LEN" where OFF is the byte offset into the message body and LEN is the total length. To avoid unnecessarily making printk format extended messages, Extended netconsole is registered with printk when the first extended netconsole is configured.

2015-06-25netconsole: make all dynamic netconsoles share a mutexTejun Heo1-5/+3
Currently, each dynamic netconsole_target uses its own separate mutex to synchronize the configuration operations. This patch replaces the per-netconsole_target mutexes with a single mutex - dynamic_netconsole_mutex. The reduced granularity doesn't hurt anything, the code is minutely simpler and this'd allow adding operations which should be synchronized across all dynamic netconsoles.

Curiously, it protects each iteration with netconsole_target_get/put() even though it never releases target_list_lock which protects all the members.

2015-06-25bnx2x: Fix linearization for encapsulated packetsYuval Mintz1-2/+7
Due to FW constraints, driver must make sure that transmitted SKBs will not be too fragmented, or in the case that they are - that each 'window' of fragments passed to the FW would contain at least an mss worth of data. For encapsultaed packets the calculation is wrong, since it ignores the inner headers in the calculation of the headers' length.

2015-06-25bnx2x: Fix statistics gathering on link changeAriel Elior1-0/+2
Since driver statistics flow access MACs and those might reset during link re-configurations, when we're about to change link properties we have to make sure that statistics are not operational. Statisics would be re-enabled [i.e., gathering of statistics would re-commence] once physical link is achieved again. Since driver employs a link-flap avoidance scheme, there are scenarios where driver will receive no indication that the new link is up, and as a result the statistics would not be re-enabled. Preventing LFA from working in such cases would guarantee that we'll always receive such indications and thus will fix statistics gathering.

The scratchpad is a shared block between all functions of a given device. Due to HW limitations, we can't properly close its parity notifications to all functions on legal flows. E.g., it's possible that while taking a register dump from one function a parity error would be triggered on other functions. Today driver doesn't consider this parity as a 'real' parity unless its being accompanied by additional indications [which would happen in a real parity scenario]; But it does print notifications for such events in the system logs. This eliminates such prints - in case of real parities driver would have additional indications; But if this is the only signal user will not even see a parity being logged in the system.
