efx_channel_get_{rx,tx}_queue() currently return NULL if the channel isn't used for traffic in that direction. In most cases this is a bug, but some callers rely on it as an existence test. Add existence test functions efx_channel_has_{rx_queue,tx_queues}() and use them as appropriate. Change efx_channel_get_{rx,tx}_queue() to assert that the requested queue exists. Remove now-redundant initialisation from efx_set_channels(). Signed-off-by: NBen Hutchings <bhutchings@solarflare.com>

efx_hard_start_xmit() needs to implement a mapping which is the inverse of tx_queue::core_txq. Move the initialisation of tx_queue::core_txq next to efx_hard_start_xmit() to make the connection more obvious. Signed-off-by: NBen Hutchings <bhutchings@solarflare.com>

If the root qdisc for a net device is mqprio, and the driver's ndo_setup_tc() operation dynamically adds and remvoes TX queues, netif_set_real_num_tx_queues() will be called during device unregistration to remove the extra TX queues when the qdisc is destroyed. Currently this causes the corresponding kobjects to be leaked, and the device's reference count never drops to 0. Signed-off-by: NBen Hutchings <bhutchings@solarflare.com>

All the cleanup code in mqprio_destroy() is currently conditional on priv->qdiscs being non-null, but that condition should only apply to the per-queue qdisc cleanup. We should always set the number of traffic classes back to 0 here. Signed-off-by: NBen Hutchings <bhutchings@solarflare.com>

In commit aa942104 ("net: init ingress queue") we moved the allocation and lock initialization of the queues into alloc_netdev_mq() since register_netdevice() is way too late. The problem is that dev->type is not setup until the setup() callback is invoked by alloc_netdev_mq(), and the dev->type is what determines the lockdep class to use for the locks in the queues. Fix this by doing the queue allocation after the setup() callback runs. This is safe because the setup() callback is not allowed to make any state changes that need to be undone on error (memory allocations, etc.). It may, however, make state changes that are undone by free_netdev() (such as netif_napi_add(), which is done by the ipoib driver's setup routine). The previous code also leaked a reference to the &init_net namespace object on RX/TX queue allocation failures. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

rtnl_link_ops->setup(), and the "setup" callback passed to alloc_netdev*(), cannot make state changes which need to be undone on failure. There is no cleanup mechanism available at this point. So we have to add the caif private instance to the global list once we are sure that register_netdev() has succedded in ->newlink(). Otherwise, if register_netdev() fails, the caller will invoke free_netdev() and we will have a reference to freed up memory on the chnl_net_list. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

The Linux IPv4 AH stack aligns the AH header on a 64 bit boundary (like in IPv6). This is not RFC compliant (see RFC4302, Section 3.3.3.2.1), it should be aligned on 32 bits. For most of the authentication algorithms, the ICV size is 96 bits. The AH header alignment on 32 or 64 bits gives the same results. However for SHA-256-128 for instance, the wrong 64 bit alignment results in adding useless padding in IPv4 AH, which is forbidden by the RFC. To avoid breaking backward compatibility, we use a new flag (XFRM_STATE_ALIGN4) do change original behavior.

Currently the driver increments the tx_timeout counter (an error counter) when simply resetting the part with outstanding transmit work pending. This is an unnecessary count of an error, when all we should be doing is just resetting the part and discarding the transmits. With this change the only increment of tx_timeout is when the stack calls the watchdog reset function due to a true Tx timeout.

Originally x25_parse_facilities returned -1 for an error 0 meaning 0 length facilities >0 the length of the facilities parsed. 5ef41308 ("x25: Prevent crashing when parsing bad X.25 facilities") introduced more error checking in x25_parse_facilities however used 0 to indicate bad parsing a6331d6f ("memory corruption in X.25 facilities parsing") followed this further for DTE facilities, again using 0 for bad parsing. The meaning of 0 got confused in the callers. If the facilities are messed up we can't determine where the data starts. So patch makes all parsing errors return -1 and ensures callers close and don't use the skb further.

Since 4-addr frames completely override the source address which will make it into the converted 802.3 frames, receiving frames for other 4-addr stations will confuse the bridging code. To be able to handle traffic for all connected devices, the bridge code will automatically turn on promiscuous mode, which triggers this problem.

Using skb_header_cloned to check if it's safe to write to the skb is not enough - mac80211 also touches the tailroom of the skb.
