2008-02-20[SCTP]: Pick up an orphaned sctp_sockets_allocated counter.Pavel Emelyanov

2008-02-19[NETFILTER]: {ip,ip6,nfnetlink}_queue: fix SKB_LINEAR_ASSERT when mangling ↵Patrick McHardy
packet data As reported by Tomas Simonaitis <tomas.simonaitis@gmail.com>, inserting new data in skbs queued over {ip,ip6,nfnetlink}_queue triggers a SKB_LINEAR_ASSERT in skb_put(). Going back through the git history, it seems this bug is present since at least 2.6.12-rc2, probably even since the removal of skb_linearize() for netfilter. Linearize non-linear skbs through skb_copy_expand() when enlarging them. Tested by Thomas, fixes bugzilla #9933. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-02-19[NET]: Messed multicast lists after dev_mc_sync/unsyncJorge Boncompte [DTI2]
Commit a0a400d79e3dd7843e7e81baa3ef2957bdc292d0 ("[NET]: dev_mcast: add multicast list synchronization helpers") from you introduced a new field "da_synced" to struct dev_addr_list that is not properly initialized to 0. So when any of the current users (8021q, macvlan, mac80211) calls dev_mc_sync/unsync they mess the address list for both devices. The attached patch fixed it for me and avoid future problems.

2008-02-17[AX25] ax25_out: check skb for NULL in ax25_kick()Jarek Poplawski
According to some OOPS reports ax25_kick tries to clone NULL skbs sometimes. It looks like a race with ax25_clear_queues(). Probably there is no need to add more than a simple check for this yet. Another report suggested there are probably also cases where ax25 ->paclen == 0 can happen in ax25_output(); this wasn't confirmed during testing but let's leave this debugging check for some time.

2008-02-12[NET]: Fix race in dev_close(). (Bug 9750)Matti Linnanvuori
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.

2008-02-12[RTNETLINK]: Send a single notification on device state changes.Laszlo Attila Toth
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.

2008-02-12[IPV6]: Fix IPsec datagram fragmentationHerbert Xu
This is a long-standing bug in the IPsec IPv6 code that breaks when we emit a IPsec tunnel-mode datagram packet. The problem is that the code the emits the packet assumes the IPv6 stack will fragment it later, but the IPv6 stack assumes that whoever is emitting the packet is going to pre-fragment the packet. In the long term we need to fix both sides, e.g., to get the datagram code to pre-fragment as well as to get the IPv6 stack to fragment locally generated tunnel-mode packet. For now this patch does the second part which should make it work for the IPsec host case. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
