When the 82598 is fed 802.1q packets, it chokes with an error of the form: ixgbe: eth0: ixgbe_tx_csum: partial checksum but proto=81! As the logic there was not smart enough to look into the vlan header to pick out the encapsulated protocol. There are times when we'd like to send these packets out without having to configure a vlan on the interface. Here we check for the vlan tag and allow the packet to go out with the correct hardware checksum. This patch is a clone of a previously submitted patch by Arthur Jones <ajones@riverbed.com> for igb (Commit - fa4a7ef3).

Modified patch with Dave's comments to replace mdelay with proper msleep. Fix 82598 copper link issue, where the phy prematurely indicates link before it is ready to process packets. The new function looks for phy link and indicates that, when it is available. If phy is not ready within few seconds of MAC indicating link, the function will return failure which translates to link down indication.

commit 654d1f8a (packet: less dev_put() calls) introduced a problem, calling potentially sleeping functions from a rcu_read_lock() protected section. Fix this by releasing lock before the sock_wmalloc()/memcpy_fromiovec() calls. After skb allocation and copy from user space, we redo device lookup and appropriate tests.

It creates a regression, triggering badness for SYN_RECV sockets, for example: [19148.022102] Badness at net/ipv4/inet_connection_sock.c:293 [19148.022570] NIP: c02a0914 LR: c02a0904 CTR: 00000000 [19148.023035] REGS: eeecbd30 TRAP: 0700 Not tainted (2.6.32) [19148.023496] MSR: 00029032 <EE,ME,CE,IR,DR> CR: 24002442 XER: 00000000 [19148.024012] TASK = eee9a820[1756] 'privoxy' THREAD: eeeca000 This is likely caused by the change in the 'estab' parameter passed to tcp_parse_options() when invoked by the functions in net/ipv4/tcp_minisocks.c But even if that is fixed, the ->conn_request() changes made in this patch series is fundamentally wrong. They try to use the listening socket's 'dst' to probe the route settings. The listening socket doesn't even have a route, and you can't get the right route (the child request one) until much later after we setup all of the state, and it must be done by hand. This stuff really isn't ready, so the best thing to do is a full revert. This reverts the following commits: f55017a9 022c3f7d 1aba721e cda42ebd 345cda2f dc343475 05eaade2 6a2a2d6bSigned-off-by: David S. Miller <davem@davemloft.net>

Make sure that any otherwise uninitialised fields of usvc are zero. This has been obvserved to cause a problem whereby the port of fwmark services may end up as a non-zero value which causes scheduling of a destination server to fail for persisitent services. As observed by Deon van der Merwe <dvdm@truteq.co.za>. This fix suggested by Julian Anastasov <ja@ssi.bg>. For good measure also zero udest.

When fragments from bridge netfilter are passed to IPv4 or IPv6 conntrack and a reassembly queue with the same fragment key already exists from reassembling a similar packet received on a different device (f.i. with multicasted fragments), the reassembled packet might continue on a different codepath than where the head fragment originated. This can cause crashes in bridge netfilter when a fragment received on a non-bridge device (and thus with skb->nf_bridge == NULL) continues through the bridge netfilter code. Add a new reassembly identifier for packets originating from bridge netfilter and use it to put those packets in insolated queues.

Currently the same reassembly queue might be used for packets reassembled by conntrack in different positions in the stack (PREROUTING/LOCAL_OUT), as well as local delivery. This can cause "packet jumps" when the fragment completing a reassembled packet is queued from a different position in the stack than the previous ones. Add a "user" identifier to the reassembly queue key to seperate the queues of each caller, similar to what we do for IPv4. Signed-off-by: Patrick McHardy <kaber@trash.net>

commit 9d3a0de7 makes slaves expire as they would do on the master with much shorter timeouts. But it introduces another problem: When we close a connection, on master server the connection became CLOSE_WAIT/TIME_WAIT, it was synced to slaves, but if master is finished within it's timeouts (CLOSE), it will not be synced to slaves. Then slaves will be kept on CLOSE_WAIT/TIME_WAIT until timeout reaches. Thus we should also sync with CLOSE.

The function efx_iterate_state contains the code memcpy(&payload->msg, payload_msg, sizeof(payload_msg)); This is the only use of payload_msg.

A valid CAN dataframe can have a data length code (DLC) of 0 .. 8 data bytes. When reading the CAN controllers register the 4-bit value may contain values from 0 .. 15 which may exceed the reserved space in the socket buffer! The ISO 11898-1 Chapter 8.4.2.3 (DLC field) says that register values > 8 should be reduced to 8 without any error reporting or frame drop. This patch introduces a new helper macro to cast a given 4-bit data length code (dlc) to __u8 and ensure the DLC value to be max. 8 bytes. The different handlings in the rx path of the CAN netdevice drivers are fixed.

I received some bug reports about userspace programs having problems because after RTM_NEWLINK was received they could not immediate access files under /proc/sys/net/ because they had not been registered yet. The original problem was trivially fixed by moving the userspace notification from rtnetlink_event() to the end of register_netdevice(). When testing that change I discovered I was still getting RTM_NEWLINK events before I could access proc and I was also getting RTM_NEWLINK events after I was seeing RTM_DELLINK. Things practically guaranteed to confuse userspace. After a little more investigation these extra notifications proved to be from the new notifiers NETDEV_POST_INIT and NETDEV_UNREGISTER_BATCH hitting the default case in rtnetlink_event, and triggering unnecessary RTM_NEWLINK messages. rtnetlink_event now explicitly handles NETDEV_UNREGISTER_BATCH and NETDEV_POST_INIT to avoid sending the incorrect userspace notifications.
