| * [NETPOLL]: Revert two bogus cleanups that broke netconsole.David S. Miller2008-03-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based upon a report by Andrew Morton and code analysis done by Jarek Poplawski. This reverts 33f807ba0d9259e7c75c7a2ce8bd2787e5b540c7 ("[NETPOLL]: Kill NETPOLL_RX_DROP, set but never tested.") and c7b6ea24b43afb5749cb704e143df19d70e23dea ("[NETPOLL]: Don't need rx_flags."). The rx_flags did get tested for zero vs. non-zero and therefore we do need those tests and that code which sets NETPOLL_RX_DROP et al. Signed-off-by: David S. Miller <davem@davemloft.net>

* | [ARP]: Introduce the arp_hdr_len helper.Pavel Emelyanov2008-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There are some place, that calculate the ARP header length. These calculations are correct, but a) some operate with "magic" constants, b) enlarge the code length (sometimes at the cost of coding style), c) are not informative from the first glance. The proposal is to introduce a helper, that includes all the good sides of these calculations. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>

| * [NEIGH]: Fix race between neighbor lookup and table's hash_rnd update.Pavel Emelyanov2008-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | The neigh_hash_grow() may update the tbl->hash_rnd value, which is used in all tbl->hash callbacks to calculate the hashval. Two lookup routines may race with this, since they call the ->hash callback without the tbl->lock held.

| * [RTNL]: Validate hardware and broadcast address attribute for RTM_NEWLINKThomas Graf2008-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RTM_NEWLINK allows for already existing links to be modified. For this purpose do_setlink() is called which expects address attributes with a payload length of at least dev->addr_len. This patch adds the necessary validation for the RTM_NEWLINK case. The address length for links to be created is not checked for now as the actual attribute length is used when copying the address to the netdevice structure. It might make sense to report an error if less than addr_len bytes are provided but enforcing this might break drivers trying to be smart with not transmitting all zero addresses.

| * [NET]: Fix race in dev_close(). (Bug 9750)Matti Linnanvuori2008-02-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a race in Linux kernel file net/core/dev.c, function dev_close. The function calls function dev_deactivate, which calls function dev_watchdog_down that deletes the watchdog timer. However, after that, a driver can call netif_carrier_ok, which calls function __netdev_watchdog_up that can add the watchdog timer again. Function unregister_netdevice calls function dev_shutdown that traps the bug !timer_pending(&dev->watchdog_timer). Moving dev_deactivate after netif_running() has been cleared prevents function netif_carrier_on from calling __netdev_watchdog_up and adding the watchdog timer again.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In do_setlink() a single notification is sent at the end of the function if any modification occured. If the address has been changed, another notification is sent. Both of them is required because originally only the NETDEV_CHANGEADDR notification was sent and although device state change implies address change, some programs may expect the original notification. It remains for compatibity. If set_operstate() is called from do_setlink(), it doesn't send a notification, only if it is called from rtnl_create_link() as earlier.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Frank Blaschka provided the bug report and the initial suggested fix for this bug. He also validated this version of this fix. The problem is that the access to neigh->arp_queue is inconsistent, we grab references when dropping the lock lock to call neigh->ops->solicit() but this does not prevent other threads of control from trying to send out that packet at the same time causing corruptions because both code paths believe they have exclusive access to the skb. The best option seems to be to hold the write lock on neigh->lock during the ->solicit() call. I looked at all of the ndisc_ops implementations and this seems workable. The only case that needs special care is the IPV4 ARP implementation of arp_solicit(). It wants to take neigh->lock as a reader to protect the header entry in neigh->ha during the emission of the soliciation. We can simply remove the read lock calls to take care of that since holding the lock as a writer at the caller providers a superset of the protection afforded by the existing read locking. The rest of the ->solicit() implementations don't care whether the neigh is locked or not. Signed-off-by: David S. Miller <davem@davemloft.net>

* [NETNS]: Namespace stop vs 'ip r l' race.Denis V. Lunev2008-01-28
| | | | | | | | | | | | | | | | | | | | During network namespace stop process kernel side netlink sockets belonging to a namespace should be closed. They should not prevent namespace to stop, so they do not increment namespace usage counter. Though this counter will be put during last sock_put. The raplacement of the correct netns for init_ns solves the problem only partial as socket to be stoped until proper stop is a valid netlink kernel socket and can be looked up by the user processes. This is not a problem until it resides in initial namespace (no processes inside this net), but this is not true for init_net. So, hold the referrence for a socket, remove it from lookup tables and only after that change namespace and perform a last put. Signed-off-by: Denis V.
