      [NET]: Make core networking code use seq_open_private · cf7732e4
      Pavel Emelyanov 提交于
      This concerns the ipv4 and ipv6 code mostly, but also the netlink
      and unix sockets.
      
      The netlink code is an example of how to use the __seq_open_private()
      call - it saves the net namespace on this private.

      [NET]: Make the device list and device lookups per namespace. · 881d966b
      Eric W. Biederman 提交于
      This patch makes most of the generic device layer network
      namespace safe.  This patch makes dev_base_head a
      network namespace variable, and then it picks up
      a few associated variables.  The functions:
      dev_getbyhwaddr
      dev_getfirsthwbytype
      dev_get_by_flags
      dev_get_by_name
      __dev_get_by_name
      dev_get_by_index
      __dev_get_by_index
      dev_ioctl
      dev_ethtool
      dev_load
      wireless_process_ioctl
      
      were modified to take a network namespace argument, and
      deal with it.
      
      vlan_ioctl_set and brioctl_set were modified so their
      hooks will receive a network namespace argument.
      
      So basically anthing in the core of the network stack that was
      affected to by the change of dev_base was modified to handle
      multiple network namespaces.  The rest of the network stack was
      simply modified to explicitly use &init_net the initial network
      namespace.  This can be fixed when those components of the network
      stack are modified to handle multiple network namespaces.
      
      For now the ifindex generator is left global.
      
      Fundametally ifindex numbers are per namespace, or else
      we will have corner case problems with migration when
      we get that far.
      
      At the same time there are assumptions in the network stack
      that the ifindex of a network device won't change.  Making
      the ifindex number global seems a good compromise until
      the network stack can cope with ifindex changes when
      you change namespaces, and the like.

      [NET]: Make device event notification network namespace safe · e9dc8653
      Eric W. Biederman 提交于
      Every user of the network device notifiers is either a protocol
      stack or a pseudo device.  If a protocol stack that does not have
      support for multiple network namespaces receives an event for a
      device that is not in the initial network namespace it quite possibly
      can get confused and do the wrong thing.
      
      To avoid problems until all of the protocol stacks are converted
      this patch modifies all netdev event handlers to ignore events on
      devices that are not in the initial network namespace.
      
      As the rest of the code is made network namespace aware these
      checks can be removed.

      [NET]: Make /proc/net per network namespace · 457c4cbc
      Eric W. Biederman 提交于
      This patch makes /proc/net per network namespace.  It modifies the global
      variables proc_net and proc_net_stat to be per network namespace.
      The proc_net file helpers are modified to take a network namespace argument,
      and all of their callers are fixed to pass &init_net for that argument.
      This ensures that all of the /proc/net files are only visible and
      usable in the initial network namespace until the code behind them
      has been updated to be handle multiple network namespaces.
      
      Making /proc/net per namespace is necessary as at least some files
      in /proc/net depend upon the set of network devices which is per
      network namespace, and even more files in /proc/net have contents
      that are relevant to a single network namespace.

      mm: Remove slab destructors from kmem_cache_create(). · 20c2df83
      Paul Mundt 提交于
      Slab destructors were no longer supported after Christoph's
      c59def9f change. They've been
      BUGs for both slab and slub, and slob never supported them
      either.
      
      This rips out support for the dtor pointer from kmem_cache_create()
      completely and fixes up every single callsite in the kernel (there were
      about 224, not including the slab allocator definitions themselves,
      or the documentation references).

      [PATCH] remove many unneeded #includes of sched.h · cd354f1a
      Tim Schmielau 提交于
      After Al Viro (finally) succeeded in removing the sched.h #include in module.h
      recently, it makes sense again to remove other superfluous sched.h includes.
      There are quite a lot of files which include it but don't actually need
      anything defined in there.  Presumably these includes were once needed for
      macros that used to live in sched.h, but moved to other header files in the
      course of cleaning it up.
      
      To ease the pain, this time I did not fiddle with any header files and only
      removed #includes from .c-files, which tend to cause less trouble.
      
      Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
      arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
      allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
      configs in arch/arm/configs on arm.  I also checked that no new warnings were
      introduced by the patch (actually, some warnings are removed that were emitted
      by unnecessarily included header files).
