qeth_l3_send_ipa_arp_cmd() is merely a wrapper around qeth_send_control_data() now. So push the length adjustment into QETH_SETASS_BASE_LEN, and remove the wrapper. While at it, also remove some redundant 0-initializations. qeth_send_setassparms() requires that callers prepare their command parameters, so that they can be copied into the parameter area in one go. Skip the indirection, and just let callers set up the command themselves. Signed-off-by: NJulian Wiedmann <jwi@linux.ibm.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Call qeth_prepare_ipa_cmd() during setup of a new IPA cmd buffer, so that it is used for all commands. Thus ARP and SNMP requests don't have to do their own initialization. This will now also set the proper MPC protocol version for SNMP requests on L2 devices. Signed-off-by: NJulian Wiedmann <jwi@linux.ibm.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Since commit 82bf5c08 ("s390/qeth: add support for IPv6 TSO"), qeth_xmit() also knows how to build TSO packets and is practically identical to qeth_l3_xmit(). Convert qeth_l3_xmit() into a thin wrapper that merely strips the L2 header off a packet, and calls qeth_xmit() for the actual TX processing.

By default, READ MAC on a Layer2 OSD device returns the adapter's burnt-in MAC address. Given the default scenario of many virtual devices on the same adapter, qeth can't make any use of this address and therefore skips the READ MAC call for this device type. But in some configurations, the READ MAC command for a Layer2 OSD device actually returns a pre-provisioned, virtual MAC address. So enable the READ MAC code to detect this situation, and let the L2 subdriver call READ MAC for OSD devices. This also removes the QETH_LAYER2_MAC_READ flag, which protects L2 devices against calling READ MAC multiple times. Instead protect the whole call to qeth_l2_request_initial_mac().

draft-ietf-nvo3-geneve-08 says: It is strongly RECOMMENDED that Path MTU Discovery ([RFC1191], [RFC1981]) be used by setting the DF bit in the IP header when Geneve packets are transmitted over IPv4 (this is the default with IPv6). Now that ICMP error handling is working for GENEVE, we can comply with this recommendation. Make this configurable, though, to avoid breaking existing setups. By default, DF won't be set. It can be set or inherited from inner IPv4 packets. If it's configured to be inherited and we are encapsulating IPv6, it will be set. This only applies to non-lwt tunnels: if an external control plane is used, tunnel key will still control the DF flag. v2: - DF behaviour configuration only applies for non-lwt tunnels, apply DF setting only if (!geneve->collect_md) in geneve_xmit_skb() (Stephen Hemminger) Signed-off-by: NStefano Brivio <sbrivio@redhat.com> Reviewed-by: NSabrina Dubroca <sd@queasysnail.net> Signed-off-by: NDavid S.

Allow users to set the IPv4 DF bit in outgoing packets, or to inherit its value from the IPv4 inner header. If the encapsulated protocol is IPv6 and DF is configured to be inherited, always set it. For IPv4, inheriting DF from the inner header was probably intended from the very beginning judging by the comment to vxlan_xmit(), but it wasn't actually implemented -- also because it would have done more harm than good, without handling for ICMP Fragmentation Needed messages. According to RFC 7348, "Path MTU discovery MAY be used". An expired RFC draft, draft-saum-nvo3-pmtud-over-vxlan-05, whose purpose was to describe PMTUD implementation, says that "is a MUST that Vxlan gateways [...] SHOULD set the DF-bit [...]", whatever that means. Given this background, the only sane option is probably to let the user decide, and keep the current behaviour as default. This only applies to non-lwt tunnels: if an external control plane is used, tunnel key will still control the DF flag. v2: - DF behaviour configuration only applies for non-lwt tunnels, move DF setting to if (!info) block in vxlan_xmit_one() (Stephen Hemminger) Signed-off-by: NStefano Brivio <sbrivio@redhat.com> Reviewed-by: NSabrina Dubroca <sd@queasysnail.net> Signed-off-by: NDavid S.

In few places in the state machine the state is set to PHY_RUNNING or PHY_NOLINK after doing a phy_read_status(). So factor this out to phy_check_link_status(). First use it in phy_start_aneg(): By setting the state to PHY_RUNNING or PHY_NOLINK directly we can remove the code to handle the case that we're using interrupts and aneg was finished already. Definition of phy_link_up and phy_link_down needs to be moved because they are called in the new function. Signed-off-by: NHeiner Kallweit <hkallweit1@gmail.com> Signed-off-by: NDavid S.

If aneg isn't finished yet then the PHY reports the link as down. There's no benefit in setting the state to PHY_AN because the next state machine run would set the status to PHY_NOLINK anyway (except in the meantime aneg has been finished and link is up). Therefore we can set the state to PHY_RUNNING or PHY_NOLINK directly. In addition change the do_carrier parameter in phy_link_down() to true. If carrier was marked as up before (what should never be the case because PHY was in state PHY_HALTED before) then we should mark it as down now.

The skb for packets that are multicast or to a link-local address are not marked as being enslaved to a VRF, if they are received on a socket bound to the VRF. This is needed for ND and it is preferable for the kernel not to have to deal with the additional use-cases if ll or mcast packets are handled as enslaved. However, this does not allow service instances listening on unbound and bound to VRF sockets to distinguish the VRF used, if packets are sent as multicast or to a link-local address. The fix is for the VRF driver to also mark these skb as being enslaved to the VRF.

When hclge_reset() is called, it may fail for several reasons. For example, an higher-level reset event occurs, memory allocation failure, hardware reset timeout, etc. Therefore, it is necessary to add corresponding error handling for these situations. 1. A high-level reset is required due to a high-level reset failure. 2. For memory allocation failure, a high-level reset is initiated by the timer to recover. The reason for using the timer is to prevent this new high-level reset to interrupt the reset process of other pf/vf; 3. For the case of hardware reset timeout, reschedule the reset task to wait for the hardware to complete the reset. For memory allocation failure and reset timeouts, in order to prevent an infinite number of scheduled reset tasks, the number of error recovery needs to be limited. This patch also add some reset related debug log printing. Signed-off-by: NHuazhong Tan <tanhuazhong@huawei.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>
