This patch makes sure that flow control packets initiated by the VF are dropped and reported as spoofed. Flow control packets can be used to limit the throughput or as DOS attack when generated from a VF. Flow control is not supported per VF hence any pause frames generated from a VF are considered malicious. Also cleaned up indentation and some redundant comments. Signed-off-by:

Remove unused members in the PHY structure and add a new member to store all the capabilities the PHY has as reported by the FW. This information will help us determine what speeds the device is capable of when link is down. Also add an enum to decode the PHY types the NVM is capable of. Use the phy_types variable to determine what phy types are possible when link is down instead of device id as it will be more accurate. When on a backplane device, we do not support changing any settings, however we should display all the phy_types we are capable of so if we see a backplane dev ID set supported and advertised purely based on the phy_types variable.

Add a module_types variable to the link_info struct to save the module information from get_phy_capabilities. This information can be used to determine which speeds the module supports. Also add a new function update_link_info which updates the module_types parameter and then calls get_link_info. This function should be called in place of get_link_info so that the module_types variable stays up-to-date with the rest of the link information. The EAS table does not reflect the values that are actually returned, so instead, basing these values on the Ethernet compliance codes specified in table 33 of SFF-8436 as these have been accurate. Use the new variable in ethtool to differentiate between a 10G/1G dual speed fiber module and a 10G only module. Change-ID: Ib7585cce321319c10ce15180054c41a6cbd41389 Signed-off-by:

In some circumstances, the firmware may fail to allocate a VSI for a VF. When this happens, the driver does not react well to the bad news and has a panic attack. To fix this problem, check the return value from i40e_alloc_vf_res and don't try to configure the device further if it failed. Additionally, explicitly clear the INIT bit when we free VF resources, so that this bit will be in the proper state in the failure case, and won't blow up elsewhere.

The driver was not correctly handling calls to its ndo_set_mac_address method. It did not properly check to see if the override would be allowed by the PF driver, and never removed the old address from its filter list. Add a new flag to the adapter struct which is set if the MAC address is assigned by the PF. Check this flag and don't allow the MAC address to be changed if it is set. Search for and properly remove the filter for the old MAC address when the new one is set. Change-ID: I817bf620c869c5a80e6a7eab65c9cbad1dc89799 Signed-off-by:

When a TCP/DCCP listener is closed, its pending SYN_RECV request sockets become stale, meaning 3WHS can not complete. But current behavior is wrong : incoming packets finding such stale sockets are dropped. We need instead to cleanup the request socket and perform another lookup : - Incoming ACK will give a RST answer, - SYN rtx might find another listener if available. - We expedite cleanup of request sockets and old listener socket.

Nikolay Aleksandrov says: ==================== bridge: vlan: cleanups & fixes (part 3) Patch 01 converts the vlgrp member to use rcu as it was already used in a similar way so better to make it official and use all the available RCU instrumentation. Patch 02 fixes a bug where the vlan_list can be traversed without rtnl or rcu held which could lead to using freed entries. Patch 03 removes some redundant code that isn't needed anymore. Patch 04 fixes a bug reported by Ido Schimmel about the vlan_flush order and switchdevs, it moves it back. v2: patch 03 and 04 are new, couldn't escape the second synchronize_rcu() since the rhtable destruction can sleep ==================== Signed-off-by: -
Nikolay Aleksandrov authored
Ido Schimmel reported a problem with switchdev devices because of the order change of del_nbp operations, more specifically the move of nbp_vlan_flush() which deletes all vlans and frees vlgrp after the rx_handler has been unregistered. So in order to fix this move vlan_flush back where it was and make it destroy the rhtable after NULLing vlgrp and waiting a grace period to make sure noone can see it. Reported-by:

The bridge and port's vlgrp member is already used in RCU way, currently we rely on the fact that it cannot disappear while the port exists but that is error-prone and we might miss places with improper locking (either RCU or RTNL must be held to walk the vlan_list). So make it official and use RCU for vlgrp to catch offenders. Introduce proper vlgrp accessors and use them consistently throughout the code. Signed-off-by:

David Ahern says: ==================== net: VRF support in IPv6 stack Initial support for VRF in IPv6 stack. Makes IPv6 functionality on par with IPv4 -- ping, tcp client/server and udp client/server all work fine. tcpdump on vrf device and external tap (e.g., host side tap device) shows all packets with proper addresses. IPv6 does not need the source address operation like IPv4. Verified vti6 works properly in my setup as does use of an IPv6 address on the VRF device. v3 - re-based to top of net-next (updates per net namespace changes by Eric) - fixed dst_entry typecasts as requested by Dave - added flags to inet6_rtm_getroute (IPv6 version of deaa0a6a) v2 - fixed CONFIG_IPV6 dependency as questioned by Cong - if IPV6 is a module, kbuild ensures VRF is a module - if IPV6 is disabled IPV6 functionality is compiled out of VRF module - addressed comments from Nik over IRC - removed duplicate call to netif_is_l3_master in l3mdev_rt6_dst_by_oif - changed allocation flag from GFP_ATOMIC to GFP_KERNEL since it is init time - added free of rt6i_pcpu - check_ipv6_frame returns false only if packet is NDISC type ==================== Signed-off-by:

commit c62987bb ("bridge: push bridge setting ageing_time down to switchdev") introduced a timer race condition because the gc_timer can get rearmed after it's supposedly stopped and flushed in br_dev_delete() leading to a use of freed memory. So take rtnl to sync with bridge destruction when setting ageing_timer.

Vivien Didelot says: ==================== net: dsa: mv88e6xxx: fix hardware bridging DSA and its drivers currently hook the NETDEV_CHANGEUPPER net_device event in order to configure the VLAN map of every port. This VLAN map is a feature of these switch chips to hardcode and restrict which output ports a given input port can egress frames to. A Linux bridge is a simple untagged VLAN propagated by the bridge code itself. With a proper 802.1Q support, a driver does not need this hook anymore, and will simply program the related VLAN object. This patchset improves the hardware bridging code in the mv88e6xxx driver with a strict 802.1Q mode. Ideally, the equivalent must be done for Broadcom Starfighter 2 and Rocker, before completely getting rid of this hook. ==================== Signed-off-by: -

Playing with the VLAN map of every port to implement "hardware bridging" in the 88E6352 driver was a hack until full 802.1Q was supported. Indeed with 802.1Q port mode "Disabled" or "Fallback", this feature is used to restrict which output ports an input port can egress frames to. A Linux bridge is an untagged VLAN. With full 802.1Q support, we don't need this hack anymore and can use the "Secure" strict 802.1Q port mode. With this mode, the port-based VLAN map still needs to be configured, but all the logic is VTU-centric. This means that the switch only cares about rules described in its hardware VLAN table, which is exactly what Linux bridge expects and what we want. Note also that the hardware bridging was broken with the previous flexible "Fallback" 802.1Q port mode. Here's an example: Port0 and Port1 belong to the same bridge. If Port0 sends crafted tagged frames with VID 200 to Port1, Port1 receives it. Even if Port1 is in hardware VLAN 200, but not Port0, Port1 will still receive it, because Fallback mode doesn't care about invalid VID or non-member source port. Signed-off-by:

Vivien Didelot authored
With 88E6352 and similar switch chips, each port has a map to restrict which output port this input port can egress frames to. The current driver code implements hardware bridging using this feature, and assigns to a bridge group the FID of its first member. Now that 802.1Q is fully implemented in this driver, a Linux bridge which is a simple untagged VLAN, already gets its own FID. This patch gets rid of the per-bridge FID and explicits the usage of the port based VLAN map feature. Signed-off-by:

Consider the following "duelling syn" sequence between two peers A and B: A B SYN1 --> <-- SYN2 SYN2ACK --> Note that the SYN/ACK has already been sent out by TCP before rds_tcp_accept_one() gets invoked as part of callbacks. If the inet_addr(A) is numerically less than inet_addr(B), the arbitration scheme in rds_tcp_accept_one() will prefer the TCP connection triggered by SYN1, and will send a CLOSE for the SYN2 (just after the SYN2ACK was sent). Since B also follows the same arbitration scheme, it will send the SYN-ACK for SYN1 that will set up a healthy ESTABLISHED connection on both sides. B will also get a CLOSE for SYN2, which should result in the cleanup of the TCP state machine for SYN2, but it should not trigger any stale RDS-TCP callbacks (such as ->writespace, ->state_change etc), that would disrupt the progress of the SYN2 based RDS-TCP connection. Thus the arbitration scheme in rds_tcp_accept_one() should restore rds_tcp callbacks for the winner before setting them up for the new accept socket, and also make sure that conn->c_outgoing is set to 0 so that we do not trigger any reconnect attempts on the passive side of the tcp socket in the future, in conformance with commit c82ac7e6 ("net/rds: RDS-TCP: only initiate reconnect attempt on outgoing TCP socket.")

Currently it's possible for someone to send a vlan range to the kernel with the pvid flag set which will result in the pvid bouncing from a vlan to vlan and isn't correct, it also introduces problems for hardware where it doesn't make sense having more than 1 pvid. iproute2 already enforces this, so let's enforce it on kernel-side as well.
