Base on cdc_ether, add the mii functions for RTL8152 and RTL8153. The RTL8152 and RTL8153 support ECM mode which use the driver of cdc_ether. Add the mii functions. Then, the basic PHY access is possible. Signed-off-by:

This change fixes an MTU sizing issue seen with gretap tunnels when non-gso packets are sent from the interface. In my case I was able to reproduce the issue by simply sending a ping of 1421 bytes with the gretap interface created on a device with a standard 1500 mtu. This fix is based on the fact that the tunnel mtu is already adjusted by dev->hard_header_len so it would make sense that any packets being compared against that mtu should also be adjusted by hard_header_len and the tunnel header instead of just the tunnel header.

In make_eligible, a mask is used to decide which groups must become eligible: the i-th group becomes eligible only if the i-th bit of the mask (from the right) is set. The mask is computed by left-shifting a 1 by a given number of places, and decrementing the result. The shift is performed on a ULL to avoid problems in case the number of places to shift is higher than 31. On a 32-bit machine, this is more costly than working on an UL. This patch replaces such a costly operation with two cheaper branches. The trick is based on the following fact: in case of a shift of at least 32 places, the resulting mask has at least the 32 less significant bits set, whereas the total number of groups is lower than 32. As a consequence, in this case it is enough to just set the 32 less significant bits of the mask with a cheaper ~0UL. In the other case, the shift can be safely performed on a UL. Reported-by:

This change makes it so that the GRE and VXLAN tunnels can make use of Tx checksum offload support provided by some drivers via the hw_enc_features. Without this fix enabling GSO means sacrificing Tx checksum offload and this actually leads to a performance regression as shown below: Utilization Send Throughput local GSO 10^6bits/s % S state 6276.51 8.39 enabled 7123.52 8.42 disabled To resolve this it was necessary to address two items. First netif_skb_features needed to be updated so that it would correctly handle the Trans Ether Bridging protocol without impacting the need to check for Q-in-Q tagging. To do this it was necessary to update harmonize_features so that it used skb_network_protocol instead of just using the outer protocol. Second it was necessary to update the GRE and UDP tunnel segmentation offloads so that they would reset the encapsulation bit and inner header offsets after the offload was complete. As a result of this change I have seen the following results on a interface with Tx checksum enabled for encapsulated frames: Utilization Send Throughput local GSO 10^6bits/s % S state 7123.52 8.42 disabled 8321.75 5.43 enabled v2: Instead of replacing refrence to skb->protocol with skb_network_protocol just replace the protocol reference in harmonize_features to allow for double VLAN tag checks.

This is a follow-up patch to 3630d400 ("ipv6: rt6_check_neigh should successfully verify neigh if no NUD information are available"). Since the removal of rt->n in rt6_info we can end up with a dst == NULL in rt6_check_neigh. In case the kernel is not compiled with CONFIG_IPV6_ROUTER_PREF we should also select a route with unkown NUD state but we must not avoid doing round robin selection on routes with the same target. So introduce and pass down a boolean ``do_rr'' to indicate when we should update rt->rr_ptr. As soon as no route is valid we do backtracking and do a lookup on a higher level in the fib trie. v2: a) Improved rt6_check_neigh logic (no need to create neighbour there) and documented return values. v3: a) Introduce enum rt6_nud_state to get rid of the magic numbers (thanks to David Miller). b) Update and shorten commit message a bit to actualy reflect the source.

vxlan exit module unregisters vxlan net and then it unregisters rtnl ops which triggers vxlan_dellink() from __rtnl_kill_links(). vxlan_dellink() deletes vxlan-dev from vxlan_list which has list-head in vxlan-net-struct but that is already gone due to net-unregister. That is how we are getting following crash. Following commit fixes the crash by fixing module exit path.

Userspace may produce vectors greater than MAX_SKB_FRAGS. When we try to linearize parts of the skb to let the rest of iov to be fit in the frags, we need count copylen into linear when calling macvtap_alloc_skb() instead of partly counting it into data_len. Since this breaks zerocopy_sg_from_iovec() since its inner counter assumes nr_frags should be zero at beginning. This cause nr_frags to be increased wrongly without setting the correct frags.

According to the commit 16b0dc29 (dummy: fix rcu_sched self-detected stalls) Eric Dumazet fix the problem in dummy, but the ifb will occur the same problem like the dummy modules. Trying to "modprobe ifb numifbs=30000" triggers : INFO: rcu_sched self-detected stall on CPU After this splat, RTNL is locked and reboot is needed. We must call cond_resched() to avoid this, even holding RTNL. Signed-off-by:
