The initio driver has for many years had two copies of the same module device table. One of them is also used for registering the other driver, the other one is entirely useless after the large scale cleanup that Alan Cox did back in 2007. The compiler warns about this whenever the driver is built-in: drivers/scsi/initio.c:131:29: warning: 'i91u_pci_devices' defined but not used [-Wunused-variable] This removes the extraneous table and the warning.

This reverts commit 00ee5927 ("net: fix __netdev_update_features return on ndo_set_features failure") and adds a comment explaining why it's okay to return a value other than 0 upon error. Some drivers might actually change flags and return an error so it's better to fire a spurious notification rather than miss these. CC: Michał Mirosław <mirq-linux@rere.qmqm.pl> Signed-off-by:

While possibly in future we don't necessarily need to use sk_buff_head.lock this is a rather larger change, as it affects the af_unix fd garbage collector, diag and socket cleanups. This is too much for a stable patch. For the time being grab sk_buff_head.lock without disabling bh and irqs, so don't use locked skb_queue_tail.

Save and restore FP/LR in BPF prog prologue and epilogue, save SP to FP in prologue in order to get the correct stack backtrace. However, ARM64 JIT used FP (x29) as eBPF fp register, FP is subjected to change during function call so it may cause the BPF prog stack base address change too. Use x25 to replace FP as BPF stack base register (fp). Since x25 is callee saved register, so it will keep intact during function call. It is initialized in BPF prog prologue when BPF prog is started to run everytime. Save and restore x25/x26 in BPF prologue and epilogue to keep them intact for the outside of BPF. Actually, x26 is unnecessary, but SP requires 16 bytes alignment. So, the BPF stack layout looks like: high original A64_SP => 0:+-----+ BPF prologue |FP/LR| current A64_FP => -16:+-----+ | ... | callee saved registers +-----+ | | x25/x26 BPF fp register => -80:+-----+ | | | ... | BPF prog stack | | | | current A64_SP => +-----+ | | | ... | Function call stack | | +-----+ low CC: Zi Shen Lim <zlim.lnx@gmail.com> CC: Xi Wang <xi.wang@gmail.com> Signed-off-by:Yang Shi <yang.shi@linaro.org> Acked-by:

ipvlan_handle_frame is a rx_handler, and when it returns a value other than RX_HANDLER_CONSUMED (here, NET_RX_DROP aka RX_HANDLER_ANOTHER), __netif_receive_skb_core expects that the skb still exists and will process it further, but we just freed it.

Sabrina Dubroca authored
Pass a **skb to ipvlan_rcv_frame so that if skb_share_check returns a new skb, we actually use it during further processing. It's safe to ignore the new skb in the ipvlan_xmit_* functions, because they call ipvlan_rcv_frame with local == true, so that dev_forward_skb is called and always takes ownership of the skb.

Vladislav Yasevich says: ==================== Fix issues with vlans without REORDER_HEADER A while ago Phil Sutter brought up an issue with vlans without REORDER_HEADER and bridges. The problem was that if a vlan without REORDER_HEADER was a port in the bridge, the bridge ended up forwarding corrupted packets that still contained the vlan header. The same issue exists for bridge mode macvlan/macvtap devices. An additional issue with vlans without REORDER_HEADER is that stacking them also doesn't work. The reason here is that skb_reorder_vlan_header() function assumes that it on ETH_HLEN bytes deep into the packet. That is not the case, when you a vlan without REORRDER_HEADER flag set. This series attempts to correct these 2 issues. 1) To solve the stacked vlans problem, the patch simply use skb->mac_len as an offset to start copying mac addresses that is part of header reordering. 2) To fix the issue with bridge/macvlan/macvtap, the second patch simply doesn't write the vlan header back to the packet if the vlan device is either a bridge or a macvlan port. This ends up being the simplest and least performance intrussive solution. I've considered extending patch 2 to all stacked devices (essentially checked for the presense of rx_handler), but that feels like a broader restriction and _may_ break existing uses. ==================== Signed-off-by: -

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. Signed-off-by:

When we have multiple stacked vlan devices all of which have turned off REORDER_HEADER flag, the untag operation does not locate the ethernet addresses correctly for nested vlans. The reason is that in case of REORDER_HEADER flag being off, the outer vlan headers are put back and the mac_len is adjusted to account for the presense of the header. Then, the subsequent untag operation, for the next level vlan, always use VLAN_ETH_HLEN to locate the begining of the ethernet header and that ends up being a multiple of 4 bytes short of the actuall beginning of the mac header (the multiple depending on the how many vlan encapsulations ethere are). As a reslult, if there are multiple levles of vlan devices with REODER_HEADER being off, the recevied packets end up being dropped. To solve this, we use skb->mac_len as the offset. The value is always set on receive path and starts out as a ETH_HLEN. The value is also updated when the vlan header manupations occur so we know it will be correct. Signed-off-by:

By default the driver allowed incorrect frames to be received. What is worse the code does not handle very short frames correctly. The FCS length is unconditionally subtracted, and the underflow can cause skb_put to be called with large number after implicit cast to unsigned. And indeed, an skb_over_panic() was observed with via-velocity. This removes the module parameter as it does not work in it's current state, and should be implemented via NETIF_F_RXALL if needed.
