Enabling TSO can lead to abysmal performances when using seg6 in encap mode, such as with the ixgbe driver. This patch adds a call to iptunnel_handle_offloads() to remove the encapsulation bit if needed.

Toshiaki Makita says: ==================== Fix vlan tag handling for vlan packets without ethernet headers Eric Dumazet reported syzbot found a new bug which leads to underflow of size argument of memmove(), causing crash[1]. This can be triggered by tun devices. The underflow happened because skb_vlan_untag() did not expect vlan packets without ethernet headers, and tun can produce such packets. I also checked vlan_insert_inner_tag() and found a similar bug. This series fixes these problems.

In some situation vlan packets do not have ethernet headers. One example is packets from tun devices. Users can specify vlan protocol in tun_pi field instead of IP protocol. When we have a vlan device with reorder_hdr disabled on top of the tun device, such packets from tun devices are untagged in skb_vlan_untag() and vlan headers will be inserted back in vlan_insert_inner_tag(). vlan_insert_inner_tag() however did not expect packets without ethernet headers, so in such a case size argument for memmove() underflowed. We don't need to copy headers for packets which do not have preceding headers of vlan headers, so skip memmove() in that case. Also don't write vlan protocol in skb->data when it does not have enough room for it.

Since commit c5ad119f ("net: sched: pfifo_fast use skb_array") driver is exposed to an issue where it is hitting NULL skbs while handling TX completions. Driver uses mmiowb() to flush the writes to the doorbell bar which is a write-combined bar, however on x86 mmiowb() does not flush the write combined buffer. This patch fixes this problem by replacing mmiowb() with wmb() after the write combined doorbell write so that writes are flushed and synchronized from more than one processor.

Global pause and PFC configuration should be mutually exclusive (i.e. only one of them at most can be set). However, once PFC was turned off, driver automatically turned Global pause on. This is a bug. Fix the driver behaviour to turn off PFC/Global once the user turned the other on. This also fixed a weird behaviour that at a current time, the profile had both PFC and global pause configuration turned on, which is Hardware-wise impossible and caused returning false positive indication to query tools. In addition, fix error code when setting global pause or PFC to change metadata only upon successful change. Also, removed useless debug print.

However, the status of dev_queue_xmit() is not returned to caller, in this case, llc_conn_state_process(). llc_conn_state_process() needs hold the skb no matter success or failure, because it still uses it after that, therefore we should hold skb before dev_queue_xmit() when that skb is the one being processed by llc_conn_state_process().

Negate ETIMEDOUT to match signed-ness of other calls. The default abort_parser callback, strp_abort_strp, sets sk->sk_err to err. Also negate the error here so sk_err always holds a positive value, as the rest of the net code expects.

Fixes a bug in the tcf_dump_walker function that can cause some actions to not be reported when dumping a large number of actions. This issue became more aggrevated when cookies feature was added. In particular this issue is manifest when large cookie values are assigned to the actions and when enough actions are created that the resulting table must be dumped in multiple batches. The number of actions returned in each batch is limited by the total number of actions and the memory buffer size. With small cookies the numeric limit is reached before the buffer size limit, which avoids the code path triggering this bug. When large cookies are used buffer fills before the numeric limit, and the erroneous code path is hit. For example after creating 32 csum actions with the cookie aaaabbbbccccdddd $ tc actions ls action csum total acts 26 action order 0: csum (tcp) action continue index 1 ref 1 bind 0 cookie aaaabbbbccccdddd ..... action order 25: csum (tcp) action continue index 26 ref 1 bind 0 cookie aaaabbbbccccdddd total acts 6 action order 0: csum (tcp) action continue index 28 ref 1 bind 0 cookie aaaabbbbccccdddd ...... action order 5: csum (tcp) action continue index 32 ref 1 bind 0 cookie aaaabbbbccccdddd Note that the action with index 27 is omitted from the report.

pci_set_drvdata() is called only after registering the net_device, therefore we could run into a NPE if one of the functions using driver_data is called before it's set. Fix this by calling pci_set_drvdata() before registering the net_device. This fix is a candidate for stable. As far as I can see the bug has been there in kernel version 3.2 already, therefore I can't provide a reference which commit is fixed by it. The fix may need small adjustments per kernel version because due to other changes the label which is jumped to if register_netdev() fails has changed over time.

When mlx5_core is loaded it is expected to sync ports with all vxlan devices so it can support vxlan encap/decap. This is done via udp_tunnel_get_rx_info(). Currently this call is set in mlx5e_nic_enable() and if the netdev is not in NETREG_REGISTERED state it will not be called. Normally on load the netdev state is not NETREG_REGISTERED so udp_tunnel_get_rx_info() will not be called. Moving udp_tunnel_get_rx_info() to mlx5e_open() so it will be called on netdev UP event and allow encap/decap.

Currently we use the global ipv6_stub var to access the ipv6 global nd table. This practice gets us to troubles when the stub is only partially set e.g when ipv6 is loaded under the disabled policy. In this case, as of commit 343d60aa ("ipv6: change ipv6_stub_impl.ipv6_dst_lookup to take net argument") the stub is not null, but stub->nd_tbl is and we crash. As we can access the ipv6 nd_tbl directly, the fix is just to avoid the reference through the stub. There is one place in the code where we issue ipv6 route lookup and keep doing it through the stub, but that mentioned commit makes sure we get -EAFNOSUPPORT from the stack.

For NIC flows, the parsed attributes are not freed when we exit successfully from mlx5e_configure_flower(). There is possible double free for eswitch flows. If error is returned from rhashtable_insert_fast(), the parse attrs will be freed in mlx5e_tc_del_flow(), but they will be freed again before exiting mlx5e_configure_flower(). To fix both issues we do the following: (1) change the condition that determines if to issue the free call to check if this flow is NIC flow, or it does not have encap action. (2) reorder the code such that that the check and free calls are done before we attempt to add into the hash table.

Add check of coalescing parameters received through ethtool are within range of values supported by the HW. Driver gets the coalescing rx/tx-usecs and rx/tx-frames as set by the users through ethtool. The ethtool support up to 32 bit value for each. However, mlx5 modify cq limits the coalescing time parameter to 12 bit and coalescing frames parameters to 16 bits. Return out of range error if user tries to set these parameters to higher values.
