Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec-next
Steffen Klassert says:
====================
One patch to rename a newly introduced struct. The rest is
the rework of the IPsec virtual tunnel interface for ipv6 to
support inter address family tunneling and namespace crossing.
1) Rename the newly introduced struct xfrm_filter to avoid a
conflict with iproute2. From Nicolas Dichtel.
2) Introduce xfrm_input_afinfo to access the address family
dependent tunnel callback functions properly.
3) Add and use a IPsec protocol multiplexer for ipv6.
4) Remove dst_entry caching. vti can lookup multiple different
dst entries, dependent of the configured xfrm states. Therefore
it does not make to cache a dst_entry.
5) Remove caching of flow informations. vti6 does not use the the
tunnel endpoint addresses to do route and xfrm lookups.
6) Update the vti6 to use its own receive hook.
7) Remove the now unused xfrm_tunnel_notifier. This was used from vti
and is replaced by the IPsec protocol multiplexer hooks.
8) Support inter address family tunneling for vti6.
9) Check if the tunnel endpoints of the xfrm state and the vti interface
are matching and return an error otherwise.
10) Enable namespace crossing for vti devices.

+If data space is exhausted the pool will either error or queue IO
+according to the configuration (see: error_if_no_space). If metadata
+space is exhausted or a metadata operation fails: the pool will error IO
+until the pool is taken offline and repair is performed to 1) fix any
+potential inconsistencies and 2) clear the flag that imposes repair.
+Once the pool's metadata device is repaired it may be resized, which
+will allow the pool to return to normal operation. Note that if a pool
+is flagged as needing repair, the pool's data and metadata devices
+cannot be resized until repair is performed. It should also be noted
+that when the pool's metadata space is exhausted the current metadata
+transaction is aborted. Given that the pool will cache IO whose
+completion may have already been acknowledged to upper IO layers
+(e.g. filesystem) it is strongly suggested that consistency checks
+(e.g. fsck) be performed on those layers when repair of the pool is
+required.

+ Altera Triple-Speed Ethernet MAC driver
+
+Copyright (C) 2008-2014 Altera Corporation
+
+This is the driver for the Altera Triple-Speed Ethernet (TSE) controllers
+using the SGDMA and MSGDMA soft DMA IP components. The driver uses the
+platform bus to obtain component resources. The designs used to test this
+driver were built for a Cyclone(R) V SOC FPGA board, a Cyclone(R) V FPGA board,
+and tested with ARM and NIOS processor hosts seperately. The anticipated use
+cases are simple communications between an embedded system and an external peer
+for status and simple configuration of the embedded system.
+
+For more information visit www.altera.com and www.rocketboards.org. Support
+forums for the driver may be found on www.rocketboards.org, and a design used
+to test this driver may be found there as well. Support is also available from
+the maintainer of this driver, found in MAINTAINERS.
+
+The Triple-Speed Ethernet, SGDMA, and MSGDMA components are all soft IP
+components that can be assembled and built into an FPGA using the Altera
+Quartus toolchain. Quartus 13.1 and 14.0 were used to build the design that
+this driver was tested against. The sopc2dts tool is used to create the
+device tree for the driver, and may be found at rocketboards.org.
+
+The driver probe function examines the device tree and determines if the
+Triple-Speed Ethernet instance is using an SGDMA or MSGDMA component. The
+probe function then installs the appropriate set of DMA routines to
+initialize, setup transmits, receives, and interrupt handling primitives for
+the respective configurations.
+
+The SGDMA component is to be deprecated in the near future (over the next 1-2
+years as of this writing in early 2014) in favor of the MSGDMA component.
+SGDMA support is included for existing designs and reference in case a
+developer wishes to support their own soft DMA logic and driver support. Any
+new designs should not use the SGDMA.
+
+The SGDMA supports only a single transmit or receive operation at a time, and
+therefore will not perform as well compared to the MSGDMA soft IP. Please
+visit www.altera.com for known, documented SGDMA errata.
+
+Scatter-gather DMA is not supported by the SGDMA or MSGDMA at this time.
+Scatter-gather DMA will be added to a future maintenance update to this
+driver.
+
+Jumbo frames are not supported at this time.
+
+The driver limits PHY operations to 10/100Mbps, and has not yet been fully
+tested for 1Gbps. This support will be added in a future maintenance update.
+
+1) Kernel Configuration
+The kernel configuration option is ALTERA_TSE:
+ Device Drivers ---> Network device support ---> Ethernet driver support --->
+ Altera Triple-Speed Ethernet MAC support (ALTERA_TSE)
+
+2) Driver parameters list:
+ debug: message level (0: no output, 16: all);
+ dma_rx_num: Number of descriptors in the RX list (default is 64);
+ dma_tx_num: Number of descriptors in the TX list (default is 64).
+
+3) Command line options
+Driver parameters can be also passed in command line by using:
+ altera_tse=dma_rx_num:128,dma_tx_num:512
+
+4) Driver information and notes
+
+4.1) Transmit process
+When the driver's transmit routine is called by the kernel, it sets up a
+transmit descriptor by calling the underlying DMA transmit routine (SGDMA or
+MSGDMA), and initites a transmit operation. Once the transmit is complete, an
+interrupt is driven by the transmit DMA logic. The driver handles the transmit
+completion in the context of the interrupt handling chain by recycling
+resource required to send and track the requested transmit operation.
+
+4.2) Receive process
+The driver will post receive buffers to the receive DMA logic during driver
+intialization. Receive buffers may or may not be queued depending upon the
+underlying DMA logic (MSGDMA is able queue receive buffers, SGDMA is not able
+to queue receive buffers to the SGDMA receive logic). When a packet is
+received, the DMA logic generates an interrupt. The driver handles a receive
+interrupt by obtaining the DMA receive logic status, reaping receive
+completions until no more receive completions are available.
+
+4.3) Interrupt Mitigation
+The driver is able to mitigate the number of its DMA interrupts
+using NAPI for receive operations. Interrupt mitigation is not yet supported
+for transmit operations, but will be added in a future maintenance release.
+
+4.4) Ethtool support
+Ethtool is supported. Driver statistics and internal errors can be taken using:
+ethtool -S ethX command. It is possible to dump registers etc.
+
+4.5) PHY Support
+The driver is compatible with PAL to work with PHY and GPHY devices.
+
+4.7) List of source files:
+ o Kconfig
+ o Makefile
+ o altera_tse_main.c: main network device driver
+ o altera_tse_ethtool.c: ethtool support
+ o altera_tse.h: private driver structure and common definitions
+ o altera_msgdma.h: MSGDMA implementation function definitions
+ o altera_sgdma.h: SGDMA implementation function definitions
+ o altera_msgdma.c: MSGDMA implementation
+ o altera_sgdma.c: SGDMA implementation
+ o altera_sgdmahw.h: SGDMA register and descriptor definitions
+ o altera_msgdmahw.h: MSGDMA register and descriptor definitions
+ o altera_utils.c: Driver utility functions
+ o altera_utils.h: Driver utility function definitions
+
+5) Debug Information
+
+The driver exports debug information such as internal statistics,
+debug information, MAC and DMA registers etc.
+
+A user may use the ethtool support to get statistics:
+e.g. using: ethtool -S ethX (that shows the statistics counters)
+or sees the MAC registers: e.g. using: ethtool -d ethX
+
+The developer can also use the "debug" module parameter to get
+further debug information.
+
+6) Statistics Support
+
+The controller and driver support a mix of IEEE standard defined statistics,
+RFC defined statistics, and driver or Altera defined statistics. The four
+specifications containing the standard definitions for these statistics are
+as follows:
+
+ o IEEE 802.3-2012 - IEEE Standard for Ethernet.
+ o RFC 2863 found at http://www.rfc-editor.org/rfc/rfc2863.txt.
+ o RFC 2819 found at http://www.rfc-editor.org/rfc/rfc2819.txt.
+ o Altera Triple Speed Ethernet User Guide, found at http://www.altera.com
+
+The statistics supported by the TSE and the device driver are as follows:
+
+"tx_packets" is equivalent to aFramesTransmittedOK defined in IEEE 802.3-2012,
+Section 5.2.2.1.2. This statistics is the count of frames that are successfully
+transmitted.
+
+"rx_packets" is equivalent to aFramesReceivedOK defined in IEEE 802.3-2012,
+Section 5.2.2.1.5. This statistic is the count of frames that are successfully
+received. This count does not include any error packets such as CRC errors,
+length errors, or alignment errors.
+
+"rx_crc_errors" is equivalent to aFrameCheckSequenceErrors defined in IEEE
+802.3-2012, Section 5.2.2.1.6. This statistic is the count of frames that are
+an integral number of bytes in length and do not pass the CRC test as the frame
+is received.
+
+"rx_align_errors" is equivalent to aAlignmentErrors defined in IEEE 802.3-2012,
+Section 5.2.2.1.7. This statistic is the count of frames that are not an
+integral number of bytes in length and do not pass the CRC test as the frame is
+received.
+
+"tx_bytes" is equivalent to aOctetsTransmittedOK defined in IEEE 802.3-2012,
+Section 5.2.2.1.8. This statistic is the count of data and pad bytes

This is used to allocate a null RxRPC key that can be used to indicate
anonymous security for a particular domain.
+
+
+=======================
+CONFIGURABLE PARAMETERS
+=======================
+
+The RxRPC protocol driver has a number of configurable parameters that can be
+adjusted through sysctls in /proc/net/rxrpc/:
+
+ (*) req_ack_delay
+
+ The amount of time in milliseconds after receiving a packet with the
+ request-ack flag set before we honour the flag and actually send the
+ requested ack.
+
+ Usually the other side won't stop sending packets until the advertised
+ reception window is full (to a maximum of 255 packets), so delaying the
+ ACK permits several packets to be ACK'd in one go.
+
+ (*) soft_ack_delay
+
+ The amount of time in milliseconds after receiving a new packet before we
+ generate a soft-ACK to tell the sender that it doesn't need to resend.
+
+ (*) idle_ack_delay
+
+ The amount of time in milliseconds after all the packets currently in the
+ received queue have been consumed before we generate a hard-ACK to tell
+ the sender it can free its buffers, assuming no other reason occurs that
+ we would send an ACK.
+
+ (*) resend_timeout
+
+ The amount of time in milliseconds after transmitting a packet before we
+ transmit it again, assuming no ACK is received from the receiver telling
+ us they got it.
+
+ (*) max_call_lifetime
+
+ The maximum amount of time in seconds that a call may be in progress
+ before we preemptively kill it.
+
+ (*) dead_call_expiry
+
+ The amount of time in seconds before we remove a dead call from the call
+ list. Dead calls are kept around for a little while for the purpose of
+ repeating ACK and ABORT packets.
+
+ (*) connection_expiry
+
+ The amount of time in seconds after a connection was last used before we
+ remove it from the connection list. Whilst a connection is in existence,
+ it serves as a placeholder for negotiated security; when it is deleted,
+ the security must be renegotiated.
+
+ (*) transport_expiry
+
+ The amount of time in seconds after a transport was last used before we
+ remove it from the transport list. Whilst a transport is in existence, it
+ serves to anchor the peer data and keeps the connection ID counter.
+
+ (*) rxrpc_rx_window_size
+
+ The size of the receive window in packets. This is the maximum number of
+ unconsumed received packets we're willing to hold in memory for any
+ particular call.
+
+ (*) rxrpc_rx_mtu
+
+ The maximum packet MTU size that we're willing to receive in bytes. This
+ indicates to the peer whether we're willing to accept jumbo packets.
+
+ (*) rxrpc_rx_jumbo_max
+
+ The maximum number of packets that we're willing to accept in a jumbo
+ packet. Non-terminal packets in a jumbo packet must contain a four byte
+ header plus exactly 1412 bytes of data. The terminal packet must contain
+ a four byte header plus any amount of data. In any event, a jumbo packet
+ may not exceed rxrpc_rx_mtu in size.

help
- This driver uses ACPI INT3403 device objects. If present, it will
- register each INT3403 thermal sensor as a thermal zone.
+ Newer laptops and tablets that use ACPI may have thermal sensors
+ outside the core CPU/SOC for thermal safety reasons. These
+ temperature sensors are also exposed for the OS to use via the so
+ called INT3403 ACPI object. This driver will, on devices that have
+ such sensors, expose the temperature information from these sensors
+ to userspace via the normal thermal framework. This means that a wide
+ range of applications and GUI widgets can show this information to
+ the user or use this information for making decisions. For example,
+ the Intel Thermal Daemon can use this information to allow the user
+ to select his laptop to run without turning on the fans.
