  • e9c5158ac   net: Allow fib_rule_unregister to batch ... Browse Code »

    Refactor the code so fib_rules_register always takes a template instead
    of the actual fib_rules_ops structure that will be used. This is
    required for network namespace support so 2 out of the 3 callers already
    do this, it allows the error handling to be made common, and it allows
    fib_rules_unregister to free the template for hte caller.

    Modify fib_rules_unregister to use call_rcu instead of syncrhonize_rcu
    to allw multiple namespaces to be cleaned up in the same rcu grace
    period.

    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.

    There is no reason for this lock to be reader/writer since
    the reader only has lock held for a very brief period.

    Adds RCU management to the list of netdevices.

    Convert some for_each_netdev() users to RCU version, if
    it can avoid read_lock-ing dev_base_lock

    Ie:
    read_lock(&dev_base_loack);
    for_each_netdev(net, dev)
    some_action();
    read_unlock(&dev_base_lock);

    becomes :

    some_action();

  • ea94ff3b5   net: Fix for dst_negative_advice ... Browse Code »

    dst_negative_advice() should check for changed dst and reset
    sk_tx_queue_mapping accordingly. Pass sock to the callers of
    dst_negative_advice.

    (sk_reset_txq is defined just for use by dst_negative_advice. The
    only way I could find to get around this is to move dst_negative_()
    from dst.h to dst.c, include sock.h in dst.c, etc)

    It's unused.

    It isn't needed -- read or write flag is already passed and sysctl

    It _was_ used in two places at arch/frv for some reason.

  • 4481374ce   mm: replace various uses of num_physpages by totalram_pages ... Browse Code »

    Sizing of memory allocations shouldn't depend on the number of physical
    pages found in a system, as that generally includes (perhaps a huge amount
    of) non-RAM pages. The amount of what actually is usable as storage
    should instead be used as a basis here.

    Some of the calculations (i.e. those not intending to use high memory)
    should likely even use (totalram_pages - totalhigh_pages).

  • 1ce85fe40   netlink: change nlmsg_notify() return value logic ... Browse Code »

    This patch changes the return value of nlmsg_notify() as follows:

    If NETLINK_BROADCAST_ERROR is set by any of the listeners and
    an error in the delivery happened, return the broadcast error;
    else if there are no listeners apart from the socket that
    requested a change with the echo flag, return the result of the
    unicast notification. Thus, with this patch, the unicast
    notification is handled in the same way of a broadcast listener
    that has set the NETLINK_BROADCAST_ERROR socket flag.

    This patch is useful in case that the caller of nlmsg_notify()
    wants to know the result of the delivery of a netlink notification
    (including the broadcast delivery) and take any action in case
    that the delivery failed. For example, ctnetlink can drop packets
    if the event delivery failed to provide reliable logging and
    state-synchronization at the cost of dropping packets.

    This patch also modifies the rtnetlink code to ignore the return
    value of rtnl_notify() in all callers. The function rtnl_notify()
    (before this patch) returned the error of the unicast notification
    which makes rtnl_set_sk_err() reports errors to all listeners. This
    is not of any help since the origin of the change (the socket that
    requested the echoing) notices the ENOBUFS error if the notification
    fails and should resync itself.
