    irttp_dup() copies a tsap_cb struct, but does not initialize the
    spinlock in the new structure, which confuses lockdep.

  • 134e63756   genetlink: make netns aware ... Browse Code »

    This makes generic netlink network namespace aware. No
    generic netlink families except for the controller family
    are made namespace aware, they need to be checked one by
    one and then set the family->netnsok member to true.

    A new function genlmsg_multicast_netns() is introduced to
    allow sending a multicast message in a given namespace,
    for example when it applies to an object that lives in
    that namespace, a new function genlmsg_multicast_allns()
    to send a message to all network namespaces (for objects
    that do not have an associated netns).

    The function genlmsg_multicast() is changed to multicast
    the message in just init_net, which is currently correct
    for all generic netlink families since they only work in
    init_net right now. Some will later want to work in all
    net namespaces because they do not care about the netns
    at all -- those will have to be converted to use one of
    the new functions genlmsg_multicast_allns() or
    genlmsg_multicast_netns() whenever they are made netns
    aware in some way.

    After this patch families can easily decide whether or
    not they should be available in all net namespaces. Many
    genl families us it for objects not related to networking
    and should therefore be available in all namespaces, but
    that will have to be done on a per family basis.

    Note that this doesn't touch on the checkpoint/restart
    problem where network namespaces could be used, genl
    families and multicast groups are numbered globally and
    I see no easy way of changing that, especially since it
    must be possible to multicast to all network namespaces
    for those families that do not care about netns.

    * 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

  • d55d87fdf   net: Move rx skb_orphan call to where needed ... Browse Code »

    In order to get the tun driver to account packets, we need to be
    able to receive packets with destructors set. To be on the safe
    side, I added an skb_orphan call for all protocols by default since
    some of them (IP in particular) cannot handle receiving packets
    destructors properly.

    Now it seems that at least one protocol (CAN) expects to be able
    to pass skb->sk through the rx path without getting clobbered.

    So this patch attempts to fix this properly by moving the skb_orphan
    call to where it's actually needed. In particular, I've added it
    to skb_set_owner_[rw] which is what most users of skb->destructor
    call.

    This is actually an improvement for tun too since it means that
    we only give back the amount charged to the socket when the skb
    is passed to another socket that will also be charged accordingly.

  • fd2120ca0   net: use NLMSG_DEFAULT_SIZE in nlmsg_new() allocations ... Browse Code »

    nlmsg_new() adds the size of the netlink header to the value
    that has been passed as parameter. If NLMSG_GOODSIZE is selected,
    we request an allocation of one memory page plus the size of the
    header. Instead, NLMSG_DEFAULT_SIZE should be used since it
    already substracts the size of the Netlink header.

    I have the impression that the similar naming in both constant
    is error prone when using it with nlmsg_new(). This is already
    documented in include/net/netlink.h

  • 99b762338   proc 2/2: remove struct proc_dir_entry::owner ... Browse Code »

    Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy
    as correctly noted at bug #12454. Someone can lookup entry with NULL
    ->owner, thus not pinning enything, and release it later resulting
    in module refcount underflow.

    We can keep ->owner and supply it at registration time like ->proc_fops
    and ->data.

    But this leaves ->owner as easy-manipulative field (just one C assignment)
    and somebody will forget to unpin previous/pin current module when
    switching ->owner. ->proc_fops is declared as "const" which should give
    some thoughts.

    ->read_proc/->write_proc were just fixed to not require ->owner for
    protection.

    rmmod'ed directories will be empty and return "." and ".." -- no harm.
    And directories with tricky enough readdir and lookup shouldn't be modular.
    We definitely don't want such modular code.

    Removing ->owner will also make PDE smaller.

    So, let's nuke it.

    Kudos to Jeff Layton for reminding about this, let's say, oversight.

  • 524ad0a79   netdevice: safe convert to netdev_priv() #part-4 ... Browse Code »

    We have some reasons to kill netdev->priv:
    1. netdev->priv is equal to netdev_priv().
    2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously
    netdev_priv() is more flexible than netdev->priv.
    But we cann't kill netdev->priv, because so many drivers reference to it
    directly.

    This patch is a safe convert for netdev->priv to netdev_priv(netdev).
    Since all of the netdev->priv is only for read.
    But it is too big to be sent in one mail.
    I split it to 4 parts and make every part smaller than 100,000 bytes,
    which is max size allowed by vger.

  • 6d9f239a1   net: '&' redux ... Browse Code »

    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.

    Move the line disciplines towards a conventional ->ops arrangement. For
    the moment the actual 'tty_ldisc' struct in the tty is kept as part of
    the tty struct but this can then be changed if it turns out that when it
    all settles down we want to refcount ldiscs separately to the tty.

    Pull the ldisc code out of /proc and put it with our ldisc code.
