Currently the functionality to untag traffic on input resides as part of the vlan module and is build only when VLAN support is enabled in the kernel. When VLAN is disabled, the function vlan_untag() turns into a stub and doesn't really untag the packets. This seems to create an interesting interaction between VMs supporting checksum offloading and some network drivers. There are some drivers that do not allow the user to change tx-vlan-offload feature of the driver. These drivers also seem to assume that any VLAN-tagged traffic they transmit will have the vlan information in the vlan_tci and not in the vlan header already in the skb. When transmitting skbs that already have tagged data with partial checksum set, the checksum doesn't appear to be updated correctly by the card thus resulting in a failure to establish TCP connections. The following is a packet trace taken on the receiver where a sender is a VM with a VLAN configued. The host VM is running on doest not have VLAN support and the outging interface on the host is tg3: 10:12:43.503055 52:54:00:ae:42:3f > 28:d2:44:7d:c2:de, ethertype 802.1Q (0x8100), length 78: vlan 100, p 0, ethertype IPv4, (tos 0x0, ttl 64, id 27243, offset 0, flags [DF], proto TCP (6), length 60) 10.0.100.1.58545 > 10.0.100.10.ircu-2: Flags [S], cksum 0xdc39 (incorrect -> 0x48d9), seq 1069378582, win 29200, options [mss 1460,sackOK,TS val 4294837885 ecr 0,nop,wscale 7], length 0 10:12:44.505556 52:54:00:ae:42:3f > 28:d2:44:7d:c2:de, ethertype 802.1Q (0x8100), length 78: vlan 100, p 0, ethertype IPv4, (tos 0x0, ttl 64, id 27244, offset 0, flags [DF], proto TCP (6), length 60) 10.0.100.1.58545 > 10.0.100.10.ircu-2: Flags [S], cksum 0xdc39 (incorrect -> 0x44ee), seq 1069378582, win 29200, options [mss 1460,sackOK,TS val 4294838888 ecr 0,nop,wscale 7], length 0 This connection finally times out. I've only access to the TG3 hardware in this configuration thus have only tested this with TG3 driver. There are a lot of other drivers that do not permit user changes to vlan acceleration features, and I don't know if they all suffere from a similar issue. The patch attempt to fix this another way. It moves the vlan header stipping code out of the vlan module and always builds it into the kernel network core. This way, even if vlan is not supported on a virtualizatoin host, the virtual machines running on top of such host will still work with VLANs enabled.

Pablo Neira Ayuso says: ==================== Netfilter fixes for net The following patchset contains fixes for your net tree, they are: 1) Unitialize the set element key and data from the commit path, otherwise this leaks chain refcount if the transaction is aborted, reported by Thomas Graf. 2) Fix crash when updating chains without no counters in nf_tables, this slipped through in the new transaction infrastructure, reported by Matteo Croce. 3) Replace all mutex_lock_interruptible() by mutex_lock() in the Netfilter tree, suggested by Patrick McHardy. This implicitly fixes the problem that Eric Dumazet reported in: http://patchwork.ozlabs.org/patch/373076/ 4) Fix error return code in nf_tables when deleting set element in nf_tables if the transaction cannot be allocated, from Julia Lawall. ==================== Signed-off-by:

Commit 1d8faf48 ("net/core: Add VF link state control") added new attribute to IFLA_VF_INFO group in rtnl_fill_ifinfo but did not adjust size of the allocated memory in if_nlmsg_size/rtnl_vfinfo_size. As the result, we may trigger warnings in rtnl_getlink and similar functions when many VF links are enabled, as the information does not fit into the allocated skb.

* Changes required due to 16eecd9b ("dcbnl : Fix misleading dcb_app->priority explanation") * Driver was previously not aware of what DCBx version was negotiated by firmware, this could lead to DCB app table in kernel or in firmware being populated wrong since IEEE/CEE used different formats made clear by above mentioned commit * Driver was missing a couple of state transitions that could be caused by other drivers that use chelsio hardware, resulting in incorrect behaviour (the change that addresses this also flips the state machine to switch on state instead of transition, hope this is okay in current window) * Prio queue info & tsa is no longer thrown away v2: Print DCBx state transition messages only when debug is enabled Signed-off-by:

This matches what the other drivers using fixed-link support do and restores the behaviour before commit 87009814 ("ucc_geth: use the new fixed PHY helpers") for the affected device trees (i.e. no phy-handle and no fixed-link).

When the driver attaches to a device that has a phy handle the probe routine returns with a reference to that node. This reference is correctly dropped in the error path and the remove function. In the fixed phy case however no reference is acquired and so the error path might drop a reference the driver isn't holding. Fix that by getting a reference to the MAC.

Make sure that fs_enet_probe is left with a reference to the phy node. In the presence of a phy handle this is already the case as of_parse_phandle returns a reference. In the fixed phy case a call to of_node_get is necessary. Otherwise the error path and remove function drop a reference the driver isn't holding.

For the fixed phy setup make sure to not overwrite a valid value of phy_dn (that is holding a reference to a phy-handle) and also acquire a reference to the MAC node to consistently return with the phy_dn pointer holding a reference. Also add the corresponding of_node_put in the error path and the remove function.

netlink doesn't set any network header offset thus when the skb is being passed to tap devices via dev_queue_xmit_nit(), it emits klog false positives due to it being unset like: ... [ 124.990397] protocol 0000 is buggy, dev nlmon0 [ 124.990411] protocol 0000 is buggy, dev nlmon0 ... So just reset the network header before passing to the device; for packet sockets that just means nothing will change - mac and net offset hold the same value just as before. Reported-by:

The line before the changed if condition is: priv->phy_node = of_parse_phandle(np, "phy-handle", 0); . If this call succeeds priv->phy_node must not be overwritten in the if block; otherwise the reference to the node returned by of_parse_phandle is lost. So add a check that the if block isn't executed in this case. Furthermore in the fixed phy case no reference is aquired for phy_node resulting in an of_node_put without holding a reference. To fix that, get a reference on the MAC dt node. Fixes: be403645 ("gianfar: use the new fixed PHY helpers") Signed-off-by:
