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

  • 405f55712   headers: smp_lock.h redux ... Browse Code »

    * 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)

  • 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.

    changed initial sk_wmem_alloc value.

    We need to take into account this offset when reporting
    sk_wmem_alloc to user, in PROC_FS files or various
    ioctls (SIOCOUTQ/TIOCOUTQ)

  • 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.

    This converts pretty much everything to print_mac. There were
    a few things that had conflicts which I have just dropped for
    now, no harm done.

    I've built an allyesconfig with this and looked at the files
    that weren't built very carefully, but it's a huge patch.

    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.

    Probably interface misuse, because of the way iterating over hashbin is done.
    However! Printing of socket number ("IrNET socket %d - ", i++") made conversion
    to proper ->start/->next difficult enough to do blindly without hardware.
    Said that, please apply.
