      Ben Hutchings authored
      
      
      The driver needs specific PHY and board support code for each SFC4000
      board; there is no point trying to continue if it is missing.
      Currently unsupported boards can trigger an 'oops'.

      sctp: Fix oops when sending queued ASCONF chunks · c0786693
      Vlad Yasevich authored
      
      
      When we finish processing ASCONF_ACK chunk, we try to send
      the next queued ASCONF.  This action runs the sctp state
      machine recursively and it's not prepared to do so.

      sctp: fix to calc the INIT/INIT-ACK chunk length correctly is set · a8170c35
      Wei Yongjun authored
      
      
      When calculating the INIT/INIT-ACK chunk length, we should not
      only account the length of parameters, but also the parameters
      zero padding length, such as AUTH HMACS parameter and CHUNKS
      parameter. Without the parameters zero padding length we may get
      following oops.

      When sctp attempts to update an assocition, it removes any

      may attempt to refrence a transport with address after removing it.

      sctp: avoid irq lock inversion while call sk->sk_data_ready() · 561b1733
      Wei Yongjun authored
      
      
      sk->sk_data_ready() of sctp socket can be called from both BH and non-BH
      contexts, but the default sk->sk_data_ready(), sock_def_readable(), can
      not be used in this case. Therefore, we have to make a new function
      sctp_data_ready() to grab sk->sk_data_ready() with BH disabling.
      
      =========================================================
      [ INFO: possible irq lock inversion dependency detected ]
      2.6.33-rc6 #129
      ---------------------------------------------------------
      sctp_darn/1517 just changed the state of lock:
       (clock-AF_INET){++.?..}, at: [<c06aab60>] sock_def_readable+0x20/0x80
      but this lock took another, SOFTIRQ-unsafe lock in the past:
       (slock-AF_INET){+.-...}
      
      and interrupts could create inverse lock ordering between them.
      
      other info that might help us debug this:

      x86/PCI: compute Address Space length rather than using _LEN · 48728e07
      Bjorn Helgaas authored
      ACPI _CRS Address Space Descriptors have _MIN, _MAX, and _LEN.  Linux has
      been computing Address Spaces as [_MIN to _MIN + _LEN - 1].  Based on the
      tests in the bug reports below, Windows apparently uses [_MIN to _MAX].
      
      Per spec (ACPI 4.0, Table 6-40), for _CRS fixed-size, fixed location
      descriptors, "_LEN must be (_MAX - _MIN + 1)", and when that's true, it
      doesn't matter which way we compute the end.  But of course, there are
      BIOSes that don't follow this rule, and we're better off if Linux handles
      those exceptions the same way as Windows.
      
      This patch makes Linux use [_MIN to _MAX], as Windows seems to do.  This
      effectively reverts d558b483 and 03db42ad and replaces them with
      simpler code.

      coda: move backing-dev.h kernel include inside __KERNEL__ · 33f60e96

      Otherwise we must export backing-dev.h as well, which doesn't make
      any sense.

      net/usb: add sierra_net.c driver · eb4fd8cd
      Elina Pasheva authored
      
      
      Re-submitted based on comments from netdev community.
      Summary of the changes:
      1. Improved error handling.
      2. Added the missing timeout arguments to usb_control_msg().
      
      The following is a new Linux driver which exposes certain models of Sierra
      Wireless modems to the operating system as Network Interface Cards (NICs).
      
      This driver requires a version of the sierra.c driver which supports
      blacklisting to work properly. The blacklist in sierra.c rejects the interfaces
      claimed by sierra_net.c. Likewise, the sierra_net.c driver only accepts
      (i.e. whitelists) the interface(s) used for USB-to-WWAN traffic.
      The version of sierra.c which supports blacklisting is
      available from the sierra wireless knowledge base page for older kernels. It is
      also available in Linux kernel starting from version 2.6.31.
      
      This driver works with all Sierra Wireless devices configured with PID=68A3
      like USB305, USB306 provided the corresponding firmware version is I2.0
      (for USB305) or M3.0 (for USB306) and later.
      This driver will not work with earlier firmware versions than the ones shown
      above. In this case the driver will issue an error message indicating
      incompatibility and will not serve the device's USB-to-WWAN interface.
      
      Sierra_net.c sits atop a pre-existing Linux driver called usbnet.c.
      A series of hook functions are provided in sierra_net.c which are called by
      usbnet.c in response to a particular condition such as receipt or transmission
      of a data packet. As such, usbnet.c does most of the work of making
      a modem appear to the system as a network device and for properly exchanging
      traffic between the USB subsystem and the Network card interface.
      Sierra_net.c is concerned with managing the data exchanged between the
      USB-to-WWAN interface and the upper layers of the operating system.

      cdc_ether: fix autosuspend for mbm devices · 55964d72
      Torgny Johansson authored
      
      
      Autosuspend works until you bring the wwan interface up, then the
      device does not enter autosuspend anymore.
      
      The following patch fixes the problem by setting the .manage_power
      field in the mbm_info struct to the same as in the cdc_info struct
      (cdc_manager_power).
