This change makes it so that the behavior for FDB handling is consistent between both the SR-IOV and non-SR-IOV cases. The main change here is that we perform bounds checking on the number of SR-IOV addresses regardless of if SR-IOV is enabled or not as we can only support a certain number of addresses in the hardware.

We shouldn't restart Admin queue subtask if PF reset fails since we do not have the AQ setup at that point. This patch makes sure we disable AQ clean subtask when PF reset fails.

Since we don't seem to be getting an LSE telling us link is going down during set_phy_config (but we do get an LSE telling us we are coming back up), fake one for the OS and tell them link is going down. Also do an atomic restart no matter what because there are times the user may want to end with link up even if they started with link down (like if they accidentally set it to a speed that can't link and are trying to fix it).

Although rhashtable library allows user to specify a quiet big size for user's created hash table, the table may be shrunk to a very small size - HASH_MIN_SIZE(4) after object is removed from the table at the first time. Subsequently, even if the total amount of objects saved in the table is quite lower than user's initial setting in a long time, the hash table size is still dynamically adjusted by rhashtable_shrink() or rhashtable_expand() each time object is inserted or removed from the table. However, as synchronize_rcu() has to be called when table is shrunk or expanded by the two functions, we should permit user to set the minimum table size through configuring the minimum number of shifts according to user specific requirement, avoiding these expensive actions of shrinking or expanding because of calling synchronize_rcu().

In commit 50cbe9ab ("net: Validate xmit SKBs right when we pull them out of the qdisc") the validation code was moved out of dev_hard_start_xmit and into dequeue_skb. However this overlooked the fact that we do not always enqueue the skb onto a qdisc. First situation is if qdisc have flag TCQ_F_CAN_BYPASS and qdisc is empty. Second situation is if there is no qdisc on the device, which is a common case for software devices. Originally spotted and inital patch by Alexander Duyck. As a result Alex was seeing issues trying to connect to a vhost_net interface after commit 50cbe9ab was applied. Added a call to validate_xmit_skb() in __dev_xmit_skb(), in the code path for qdiscs with TCQ_F_CAN_BYPASS flag, and in __dev_queue_xmit() when no qdisc. Also handle the error situation where dev_hard_start_xmit() could return a skb list, and does not return dev_xmit_complete(rc) and falls through to the kfree_skb(), in that situation it should call kfree_skb_list().

Sathya Perla says: ==================== be2net: patch set v2 changes: add a new line after variable declaration in patch 12. *** Patch 1 adds a few new log messages to help debugging in failure cases. Patch 2 uses new macros for parsing RX/TX completions and TX wrbs to help shorten the lines. Patch 3 adds a description for the RX counter rx_input_fifo_overflow_drop. Patch 4 adds TX completion error statistics reporting via ethtool. Patch 5 adds a dma_mapping_error counter and its reporting via ethtool. Patch 6 fixes up log messages in the Lancer FW download path. Patch 7 replaces gotos with direct return statements. Patch 8 cleans up be_change_mtu() code by using a new macro BE_MAX_MTU Patch 9 makes be_cmd_get_regs() routine to return an integer status similar to other FW cmd routines in be_cmds.c Patch 10 gets rid of TX budget as enforcing a budget on TX completion processing in NAPI is neither suggested nor it provides a performance benefit. Patch 11 defines and uses a new macro for_all_tx_queues_on_eq() similar to the RX processing code. Patch 12 queries max_tx_qs from the FW for BE3 super-nic profiles. For those profiles, the driver cannot assume a constant BE3_MAX_TX_QS value, as the value may change for each function. Please consider applying this patch set to the net-next tree.

sk->sk_error_queue is dequeued in four locations. All share the exact same logic. Deduplicate. Also collapse the two critical sections for dequeue (at the top of the recv handler) and signal (at the bottom). This moves signal generation for the next packet forward, which should be harmless. It also changes the behavior if the recv handler exits early with an error. Previously, a signal for follow-up packets on the errqueue would then not be scheduled. The new behavior, to always signal, is arguably a bug fix. For rxrpc, the change causes the same function to be called repeatedly for each queued packet (because the recv handler == sk_error_report). It is likely that all packets will fail for the same reason (e.g., memory exhaustion). This code runs without sk_lock held, so it is not safe to trust that sk->sk_err is immutable inbetween releasing q->lock and the subsequent test. Introduce int err just to avoid this potential race.

Tom Herbert says: ==================== net: Checksum offload changes - Part VI I am working on overhauling RX checksum offload. Goals of this effort are: - Specify what exactly it means when driver returns CHECKSUM_UNNECESSARY - Preserve CHECKSUM_COMPLETE through encapsulation layers - Don't do skb_checksum more than once per packet - Unify GRO and non-GRO csum verification as much as possible - Unify the checksum functions (checksum_init) - Simplify code What is in this seventh patch set: - Add skb->csum. This allows a device or GRO to indicate that an invalid checksum was detected. - Checksum unncessary to checksum complete conversions. With these changes, I believe that the third goal of the overhaul is now mostly achieved. In the case of no encapsulation or one layer of encapsulation, there should only be at most one skb_checksum over each packet (between GRO and normal path). In the case of two layers of encapsulation, it is still possible with the right combination of non-zero and zero UDP checksums to have >1 skb_checksum. For instance: IP>GRE(with csum)>IP>UDP(zero csum)>VXLAN>IP>UDP(non-zero csum), would likely necessiate an skb_checksum in GRO and normal path. This doesn't seem like a common scenario at all so I'm inclined to not address this now, if multiple layers of encapsulation becomes popular we can reassess. Note that checksum conversion shows a nice improvement for RX VXLAN when outer UDP checksum is enabled (12.65% CPU compared to 20.94%). This is not only from the fact that we don't need checksum calculation on the host, but also allows GRO for VXLAN in this case. Checksum conversion does not help send side (which still needs to perform a checksum on host). For that we will implement remote checksum offload in a later patch (http://tools.ietf.org/html/draft-herbert-remotecsumoffload-00). Please review carefully and test if possible, mucking with basic checksum functions is always a little precarious :-) ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>
