Sometimes the drivers and other code would find it handy to know some internal information about upper device being changed. So allow upper-code to pass information down to notifier listeners during linking. Signed-off-by: NJiri Pirko <jiri@mellanox.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

If tcp_send_ack() can not allocate skb, we properly handle this and setup a timer to try later. Use __GFP_NOWARN to avoid polluting syslog in the case host is under memory pressure, so that pertinent messages are not lost under a flood of useless information. sk_gfp_atomic() can use its gfp_mask argument (all callers currently were using GFP_ATOMIC before this patch) We rename sk_gfp_atomic() to sk_gfp_mask() to clearly express this function now takes into account its second argument (gfp_mask) Note that when tcp_transmit_skb() is called with clone_it set to false, we do not attempt memory allocations, so can pass a 0 gfp_mask, which most compilers can emit faster than a non zero or constant value.

The rndis header is 116 bytes big and can be placed in the default head room that will be available in the skb. Since the netvsc packet is less than 48 bytes, we can use the skb control buffer for the netvsc packet. With these changes we don't need to ask for additional head room. Signed-off-by: NK. Y.

The hci_connect_le_scan() is (as the name implies) a master/central role API, so it makes no sense in passing a role parameter to it.

Since discovery also deals with LE scanning it makes sense to move it behind the same req_workqueue as other LE scanning changes. This also simplifies the logic since we do many of the actions in a synchronous manner. Part of this refactoring is moving hci_req_stop_discovery() to hci_request.c. At the same time the function receives support for properly handling the STOPPING state since that's the state we'll be in when stopping through the req_workqueue.

To enable controller specific logging, the userspace daemon has to have the ability to log per controller. To facilitate this support, provide a dedicated logging channel. Messages in this channel will be included in the monitor queue and with that also forwarded to monitoring tools along with the actual hardware traces. All messages from the logging channel are timestamped and with that allow an easy correlation between userspace messages and hardware events. This will increase the ability to debug problems faster.

由 Eric Dumazet 提交于
NAPI drivers no longer need to observe a particular protocol to benefit from busy polling (CONFIG_NET_RX_BUSY_POLL=y) napi_hash_add() and napi_hash_del() are automatically called from core networking stack, respectively from netif_napi_add() and netif_napi_del() This patch depends on free_netdev() and netif_napi_del() being called from process context, which seems to be the norm. Drivers might still prefer to call napi_hash_del() on their own, since they might combine all the rcu grace periods into a single one, knowing their NAPI structures lifetime, while core networking stack has no idea of a possible combining. Once this patch proves to not bring serious regressions, we will cleanup drivers to either remove napi_hash_del() or provide appropriate rcu grace periods combining.

skb->sender_cpu and skb->napi_id share a common storage, and we had various bugs about this. We had to call skb_sender_cpu_clear() in some places to not leave a prior skb->napi_id and fool netdev_pick_tx() As suggested by Alexei, we could split the space so that these errors can not happen. 0 value being reserved as the common (not initialized) value, let's reserve [1 .. NR_CPUS] range for valid sender_cpu, and [NR_CPUS+1 .. ~0U] for valid napi_id. This will allow proper busy polling support over tunnels.

When a vlan is configured with REORDER_HEADER set to 0, the vlan header is put back into the packet and makes it appear that the vlan header is still there even after it's been processed. This posses a problem for bridge and macvlan ports. The packets passed to those device may be forwarded and at the time of the forward, vlan headers end up being unexpectedly present. With the patch, we make sure that we do not put the vlan header back (when REORDER_HEADER is 0) if a bridge or macvlan has been configured on top of the vlan device.
