  • Now that sys_sysctl is a compatiblity wrapper around /proc/sys
    all sysctl strategy routines, and all ctl_name and strategy
    entries in the sysctl tables are unused, and can be
    revmoed.

    In addition neigh_sysctl_register has been modified to no longer
    take a strategy argument and it's callers have been modified not
    to pass one.

  • The x25 driver uses lock_kernel() implicitly through
    its proto_ops wrapper. The makes the usage explicit
    in order to get rid of that wrapper and to better document
    the usage of the BKL.

    The next step should be to get rid of the usage of the BKL
    in x25 entirely, which requires understanding what data
    structures need serialized accesses.

  • The generic __sock_create function has a kern argument which allows the
    security system to make decisions based on if a socket is being created by
    the kernel or by userspace. This patch passes that flag to the
    net_proto_family specific create function, so it can do the same thing.

  • If there is data, the unsigned skb->len is greater than 0.

    rt.sigdigits is unsigned as well, so the test `>= 0' is
    always true, the other part of the test catches wrapped

  • Looking at commit ebc3f64b864f it appears that this was intended
    and not the original, equivalent to `if (facilities.reverse & ~0x81)'.

    In x25_parse_facilities() that patch changed how facilities->reverse
    was set. No other bits were set than 0x80 and/or 0x01.

    level instead of depending upon (sometimes non-trivial)
    checks against this sprinkled all over the the place, in
    each and every implementation.

    from Linus Torvalds.

  • * Remove smp_lock.h from files which don't need it (including some headers!)
    * Add smp_lock.h to files which do need it
    * Make smp_lock.h include conditional in hardirq.h
    It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT

    This will make hardirq.h inclusion cheaper for every PREEMPT=n config
    (which includes allmodconfig/allyesconfig, BTW)

    (net: No more expensive sock_hold()/sock_put() on each tx)
    changed initial sk_wmem_alloc value.

    Some protocols check sk_wmem_alloc value to determine if a timer
    must delay socket deallocation. We must take care of the sk_wmem_alloc
    value being one instead of zero when no write allocations are pending.

    Reported by Ingo Molnar, and full diagnostic from David Miller.

    This patch introduces three helpers to get read/write allocations
    and a followup patch will use these helpers to report correct
    write allocations to user.

  • skb->len is an unsigned int, so the test in x25_rx_call_request() always
    evaluates to true.

    len in x25_sendmsg() is unsigned as well. so -ERRORS returned by x25_output()
    are not noticed.

  • I want to compile out proc_* and sysctl_* handlers totally and
    stub them to NULL depending on config options, however usage of &
    will prevent this, since taking adress of NULL pointer will break
    compilation.

    So, drop & in front of every ->proc_handler and every ->strategy
    handler, it was never needed in fact.

  • The function x25_get_neigh increments a reference count. At the point of
    the second goto out, the result of calling x25_get_neigh is only stored in
    a local variable, and thus no one outside the function will be able to
    decrease the reference count. Thus, x25_neigh_put should be called before
    the return in this case.

    The problem was found using the following semantic match.

  • Finally, the zero_it argument can be completely removed from
    the callers and from the function prototype.

    Besides, fix the checkpatch.pl warnings about using the
    assignments inside if-s.

    This patch is rather big, and it is a part of the previous one.
    I splitted it wishing to make the patches more readable. Hope
    this particular split helped.

  • 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.

  • 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.

  • This patch modifies every packet receive function
    registered with dev_add_pack() to drop packets if they
    are not from the initial network namespace.

    This should ensure that the various network stacks do
    not receive packets in a anything but the initial network
    namespace until the code has been converted and is ready
    for them.

  • This patch passes in the namespace a new socket should be created in
    and has the socket code do the appropriate reference counting. By
    virtue of this all socket create methods are touched. In addition
    the socket create methods are modified so that they will fail if
    you attempt to create a socket in a non-default network namespace.

    Failing if we attempt to create a socket outside of the default
    network namespace ensures that as we incrementally make the network stack
    network namespace aware we will not export functionality that someone
    has not audited and made certain is network namespace safe.
    Allowing us to partially enable network namespaces before all of the
    exotic protocols are supported.

    Any protocol layers I have missed will fail to compile because I now
    pass an extra parameter into the socket creation code.
