When we clone the SKB, we forget about the original one. Avoid this problem by using skb_share_check(). Reported-by:

Unfortunately we have to use a real modulus here as the multiply trick won't work as effectively with cpu numbers as it does with rxhash values. Signed-off-by: -

This patch add an unsolicited notification of the DCBX negotiated parameters for the CEE flavor of the DCBX protocol. The notification message is identical to the aggregated CEE get operation and holds all the pertinent local and peer information. The notification routine is exported so it can be invoked by drivers supporting an embedded DCBX stack. Signed-off-by:

The following couple of patches add dcbnl an unsolicited notification of the the DCB configuration for the CEE flavor of the DCBX protocol. This is useful when the user-mode DCB client is not responsible for conducting and resolving the DCBX negotiation (either because the DCBX stack is embedded in the HW or the negotiation is handled by another agent in the host), but still needs to get the negotiated parameters. This functionality already exists for the IEEE flavor of the DCBX protocol and these patches add it to the older CEE flavor. The first patch extends the CEE attribute GET operation to include not only the peer information, but also all the pertinent local configuration (negotiated parameters). The second patch adds and export a CEE specific notification routine. Signed-off-by:

Just add GSO to vlan_features initialization, and update comments. When we set offload features, vlan_dev_fix_features() will do more check. In vlan_dev_fix_features(), final features is decided by features of real device and vlan_features of real device. Signed-off-by:

The skb->rxhash cannot be properly computed if the packet is a fragment. To alleviate this, allow the AF_PACKET client to ask for defragmentation to be done at demux time. Signed-off-by: -

Fanouts allow packet capturing to be demuxed to a set of AF_PACKET sockets. Two fanout policies are implemented: 1) Hashing based upon skb->rxhash 2) Pure round-robin An AF_PACKET socket must be fully bound before it tries to add itself to a fanout. All AF_PACKET sockets trying to join the same fanout must all have the same bind settings. Fanouts are identified (within a network namespace) by a 16-bit ID. The first socket to try to add itself to a fanout with a particular ID, creates that fanout. When the last socket leaves the fanout (which happens only when the socket is closed), that fanout is destroyed. Signed-off-by: -

If gso/gro feature of underlying device is turned off， then new created vlan device never can turn gso/gro on. Although underlying device don't support TSO, we still should use software segments for vlan device. Signed-off-by:

If the rx ring is completely empty, then the device may never fire an rx interrupt. Unfortunately, the rx interrupt is what triggers populating the rx ring with fresh buffers, so this will cause networking to lock up. This patch replenishes the skb in recv descriptor as soon as it is peeled off while processing rx completions. If the skb/buffer allocation fails, existing one is recycled and the packet in hand is dropped. This way none of the RX desc is ever left empty, thus avoiding starvation Signed-off-by:

As is_multicast_ether_addr returns true on broadcast packets as well, we need to explicitly exclude broadcast packets so that they're always flooded. This wasn't an issue before as broadcast packets were considered to be an unregistered multicast group, which were always flooded. However, as we now only flood such packets to router ports, this is no longer acceptable. Reported-by:

The version number of modules build outside of the tree can get revision numbers added. This is useful to give hints about the revision of a distribution package and the used patchset. The prepended source number or branch name doesn't add any additional information which would help to identify problems and can therefore be omitted. Signed-off-by:

The packet aggregation needs to ensure that only compatible packets are aggregated. Some of the checks are based on the interface number while assuming that the first interface also is the primary interface which is not always the case. This patch addresses the issue by using the primary_if pointer. Reported-by:

The primary interface OGM has to be broadcasted on all hard-interfaces even if the primary interface is not the first interface (if_num = 0). Therefore the code has to compare the originating interface with the primary interface instead of checking the if_num. Reported-by:

The tt_local_entry structure now has a 'flags' field. This helps to unify the flags format to all the client related structures (tt_global_entry and tt_change). The 'never_purge' field is now encoded in the 'flags' one. To optimise the usage of this field, its length has been increased to 16bit in order to use the eight leading bits (from 0 to 7) to store flags that have to be sent on the wire, while the eight ending ones are used for local computation only. Moreover 'enum tt_change_flags' is now called 'enum tt_client_flags' and the defined values apply to the tt_local_entry, tt_global_entry and the tt_change 'flags' field. Signed-off-by:

Hi, Reinhard Max also pointed out that the error should EAFNOSUPPORT according to POSIX. The Linux manpages have it as EINVAL, some other OSes (Minix, HPUX, perhaps BSD) use EAFNOSUPPORT. Windows uses WSAEFAULT according to MSDN. Other protocols error values in their af bind() methods in current mainline git as far as a brief look shows: EAFNOSUPPORT: atm, appletalk, l2tp, llc, phonet, rxrpc EINVAL: ax25, bluetooth, decnet, econet, ieee802154, iucv, netlink, netrom, packet, rds, rose, unix, x25, No check?: can/raw, ipv6/raw, irda, l2tp/l2tp_ip Ciao, Marcus Signed-off-by:
