2018-03-30PCI/portdrv: Simplify PCIe feature permission checkingBjorn Helgaas
Some PCIe features (AER, DPC, hotplug, PME) can be managed by either the platform firmware or the OS, so the host bridge driver may have to request permission from the platform before using them. On ACPI systems, this is done by negotiate_os_control() in acpi_pci_root_add(). The PCIe port driver later uses pcie_port_platform_notify() and pcie_port_acpi_setup() to figure out whether it can use these features. But all we need is a single bit for each service, so these interfaces are needlessly complicated. Simplify this by adding bits in the struct pci_host_bridge to show when the OS has permission to use each feature: + unsigned int native_aer:1; /* OS may use PCIe AER */ + unsigned int native_hotplug:1; /* OS may use PCIe hotplug */ + unsigned int native_pme:1; /* OS may use PCIe PME */ These are set when we create a host bridge, and the host bridge driver can clear the bits corresponding to any feature the platform doesn't want us to use.

2018-03-30vlan: Fix vlan insertion for packets without ethernet headerToshiaki Makita
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.

2018-03-30net: Call add/kill vid ndo on vlan filter feature togglingGal Pressman
NETIF_F_HW_VLAN_[CS]TAG_FILTER features require more than just a bit flip in dev->features in order to keep the driver in a consistent state. These features notify the driver of each added/removed vlan, but toggling of vlan-filter does not notify the driver accordingly for each of the existing vlans. This patch implements a similar solution to NETIF_F_RX_UDP_TUNNEL_PORT behavior (which notifies the driver about UDP ports in the same manner that vids are reported). Each toggling of the features propagates to the 8021q module, which iterates over the vlans and call add/kill ndo accordingly.

2018-03-30netfilter: ebtables: Add support for specifying match revisionBernie Harris
Currently ebtables assumes that the revision number of all match modules is 0, which is an issue when trying to use existing xtables matches with ebtables. The solution is to modify ebtables to allow extensions to specify a revision number, similar to iptables. This gets passed down to the kernel, which is then able to find the match module correctly. To main binary backwards compatibility, the size of the ebt_entry structures is not changed, only the size of the name field is decreased by 1 byte to make room for the revision field.
