      net: network device name ifalias support · 0b815a1a
      Stephen Hemminger authored
      This patch add support for keeping an additional character alias
      associated with an network interface. This is useful for maintaining
      the SNMP ifAlias value which is a user defined value. Routers use this
      to hold information like which circuit or line it is connected to. It
      is just an arbitrary text label on the network device.
      
      There are two exposed interfaces with this patch, the value can be
      read/written either via netlink or sysfs.
      
      This could be maintained just by the snmp daemon, but it is more
      generally useful for other management tools, and the kernel is good
      place to act as an agreed upon interface to store it.

      bonding: Allow setting max_bonds to zero · b8a9787e
      Jay Vosburgh authored
      	Permit bonding to function rationally if max_bonds is set to
      zero.  This will load the module, but create no master devices (which can
      be created via sysfs).
      
      	Requires some change to bond_create_sysfs; currently, the
      netdev sysfs directory is determined from the first bonding device created,
      but this is no longer possible.  Instead, an interface from net/core is
      created to create and destroy files in net_class.
      
      	Based on a patch submitted by Phil Oester <kernel@linuxaces.com>.
      Modified by Jay Vosburgh to fix the sysfs issue mentioned above and to
      update the documentation.

      netns: Fix device renaming for sysfs · aaf8cdc3
      Daniel Lezcano authored
      When a netdev is moved across namespaces with the
      'dev_change_net_namespace' function, the 'device_rename' function is
      used to fixup kobject and refresh the sysfs tree. The device_rename
      function will call kobject_rename and this one will check if there is
      an object with the same name and this is the case because we are
      renaming the object with the same name.
      
      The use of 'device_rename' seems for me wrong because we usually don't
      rename it but just move it across namespaces. As we just want to do a
      mini "netdev_[un]register", IMO the functions
      'netdev_[un]register_kobject' should be used instead, like an usual
      network device [un]registering.
      
      This patch replace device_rename by netdev_unregister_kobject,
      followed by netdev_register_kobject.
      
      The netdev_register_kobject will call device_initialize and will raise
      a warning indicating the device was already initialized. In order to
      fix that, I split the device initialization into a separate function
      and use it together with 'netdev_register_kobject' into
      register_netdevice. So we can safely call 'netdev_register_kobject' in
      'dev_change_net_namespace'.
      
      This fix will allow to properly use the sysfs per namespace which is
      coming from -mm tree.

      Driver core: change add_uevent_var to use a struct · 7eff2e7a
      Kay Sievers authored
      This changes the uevent buffer functions to use a struct instead of a
      long list of parameters. It does no longer require the caller to do the
      proper buffer termination and size accounting, which is currently wrong
      in some places. It fixes a known bug where parts of the uevent
      environment are overwritten because of wrong index calculations.
      
      Many thanks to Mathieu Desnoyers for finding bugs and improving the
      error handling.

      [NET]: Fix running without sysfs · 8b41d188
      Eric W. Biederman authored
      When sysfs support is compiled out the kernel still keeps and maintains
      the kobject tree.  So it is not safe to skip our kobject reference counting or
      to avoid becoming members of the kobject tree.  It is safe to not add
      the networking specific sysfs attributes.
      
      This patch removes the sysfs special cases from net/core/dev.c
      renames functions from netdev_sysfs_xxxx to netdev_kobject_xxxx
      and always compiles in net-sysfs.c
      
      net-sysfs.c is modified with a CONFIG_SYSFS guard around the parts
      that are actually sysfs specific.

      [NET]: Make NAPI polling independent of struct net_device objects. · bea3348e
      Stephen Hemminger authored
      Several devices have multiple independant RX queues per net
      device, and some have a single interrupt doorbell for several
      queues.
      
      In either case, it's easier to support layouts like that if the
      structure representing the poll is independant from the net
      device itself.
      
      The signature of the ->poll() call back goes from:
      
      	int foo_poll(struct net_device *dev, int *budget)
      
      to
      
      	int foo_poll(struct napi_struct *napi, int budget)
      
      The caller is returned the number of RX packets processed (or
      the number of "NAPI credits" consumed if you want to get
      abstract).  The callee no longer messes around bumping
      dev->quota, *budget, etc. because that is all handled in the
      caller upon return.
      
      The napi_struct is to be embedded in the device driver private data
      structures.
      
      Furthermore, it is the driver's responsibility to disable all NAPI
      instances in it's ->stop() device close handler.  Since the
      napi_struct is privatized into the driver's private data structures,
      only the driver knows how to get at all of the napi_struct instances
      it may have per-device.
      
      With lots of help and suggestions from Rusty Russell, Roland Dreier,
      Michael Chan, Jeff Garzik, and Jamal Hadi Salim.
      
      Bug fixes from Thomas Graf, Roland Dreier, Peter Zijlstra,
      Joseph Fannin, Scott Wood, Hans J. Koch, and Michael Chan.
      
      [ Ported to current tree and all drivers converted.  Integrated
        Stephen's follow-on kerneldoc additions, and restored poll_list
        handling to the old style to fix mutual exclusion issues.  -DaveM ]

      [PATCH] WE-21 support (core API) · baef1865
      John W. Linville authored
      This is version 21 of the Wireless Extensions. Changelog :
      	o finishes migrating the ESSID API (remove the +1)
      	o netdev->get_wireless_stats is no more
      	o long/short retry
      
      This is a redacted version of a patch originally submitted by Jean
      Tourrilhes.  I removed most of the additions, in order to minimize
      future support requirements for nl80211 (or other WE successor).

      [NET] core: add RFC2863 operstate · b00055aa
      Stefan Rompf authored
      this patch adds a dormant flag to network devices, RFC2863 operstate derived
      from these flags and possibility for userspace interaction. It allows drivers
      to signal that a device is unusable for user traffic without disabling
      queueing (and therefore the possibility for protocol establishment traffic to
      flow) and a userspace supplicant (WPA, 802.1X) to mark a device unusable
      without changes to the driver.
      
      It is the result of our long discussion. However I must admit that it
      represents what Jamal and I agreed on with compromises towards Krzysztof, but
      Thomas and Krzysztof still disagree with some parts. Anyway I think it should
      be applied.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
