In 7af137b72131 ("selftests: net: Introduce first PMTU test") I accidentally assumed route_get_* helpers would run from a single namespace. Make them a bit more generic, by passing the namespace command prefix as a parameter instead.

David suggests it's more intuitive to return non-zero on failures, and zero on success. No need to introduce tail 'return 0' in functions, they will return the exit code of the last command anyway.

Thomas Falcon says: ==================== ibmvnic: Update TX pool and TX routines This patch restructures the TX pool data structure and provides a separate TX pool array for TSO transmissions. This is already used in some way due to our unique DMA situation, namely that we cannot use single DMA mappings for packet data. Previously, both buffer arrays used the same pool entry. This restructuring allows for some additional cleanup in the driver code, especially in some places in the device transmit routine. In addition, it allows us to more easily track the consumer and producer indexes of a particular pool. This has been further improved by better tracking of in-use buffers to prevent possible data corruption in case an invalid buffer entry is used. v5: Fix bisectability mistake in the first patch. Removed TSO-specific data in a later patch when it is no longer used. v4: Fix error in 7th patch that causes an oops by using the older fixed value for number of buffers instead of the respective field in the tx pool data structure v3: Forgot to update TX pool cleaning function to handle new data structures. Included 7th patch for that. v2: Fix typo in 3/6 commit subject line ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Improve TX pool buffer accounting to prevent the producer index from overruning the consumer. First, set the next free index to an invalid value if it is in use. If next buffer to be consumed is in use, drop the packet. Finally, if the transmit fails for some other reason, roll back the consumer index and set the free map entry to its original value. This should also be done if the DMA map fails. Signed-off-by: NThomas Falcon <tlfalcon@linux.vnet.ibm.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Update TX and TX completion routines to account for TX pool restructuring. TX routine first chooses the pool depending on whether a packet is GSO or not, then uses it accordingly. For the completion routine to know which pool it needs to use, set the most significant bit of the correlator index to one if the packet uses the TSO pool. On completion, unset the bit and use the correlator index to release the buffer pool entry. Signed-off-by: NThomas Falcon <tlfalcon@linux.vnet.ibm.com> Signed-off-by: NDavid S.

In VLAN_AWARE mode CPSW can insert VLAN header encapsulation word on Host port 0 egress (RX) before the packet data if RX_VLAN_ENCAP bit is set in CPSW_CONTROL register. VLAN header encapsulation word has following format: HDR_PKT_Priority bits 29-31 - Header Packet VLAN prio (Highest prio: 7) HDR_PKT_CFI bits 28 - Header Packet VLAN CFI bit. HDR_PKT_Vid bits 27-16 - Header Packet VLAN ID PKT_Type bits 8-9 - Packet Type. Indicates whether the packet is VLAN-tagged, priority-tagged, or non-tagged. 00: VLAN-tagged packet 01: Reserved 10: Priority-tagged packet 11: Non-tagged packet This feature can be used to implement TX VLAN offload in case of VLAN-tagged packets and to insert VLAN tag in case Non-tagged packet was received on port with PVID set. As per documentation, CPSW never modifies packet data on Host egress (RX) and as result, without this feature enabled, Host port will not be able to receive properly packets which entered switch non-tagged through external Port with PVID set (when non-tagged packet forwarded from external Port with PVID set to another external Port - packet will be VLAN tagged properly). Implementation details: - on RX driver will check CPDMA status bit RX_VLAN_ENCAP BIT(19) in CPPI descriptor to identify when VLAN header encapsulation word is present. - PKT_Type = 0x01 or 0x02 then ignore VLAN header encapsulation word and pass packet as is; - if HDR_PKT_Vid = 0 then ignore VLAN header encapsulation word and pass packet as is; - In dual mac mode traffic is separated between ports using default port vlans, which are not be visible to Host and so should not be reported. Hence, check for default port vlans in dual mac mode and ignore VLAN header encapsulation word; - otherwise fill SKB with VLAN info using __vlan_hwaccel_put_tag(); - PKT_Type = 0x00 (VLAN-tagged) then strip out VLAN header from SKB.

Publications for TIPC_CLUSTER_SCOPE and TIPC_ZONE_SCOPE are in all aspects handled the same way, both on the publishing node and on the receiving nodes. Despite previous ambitions to the contrary, this is never going to change, so we take the conseqeunce of this and obsolete TIPC_ZONE_SCOPE and related macros/functions. Whenever a user is doing a bind() or a sendmsg() attempt using ZONE_SCOPE we translate this internally to CLUSTER_SCOPE, while we remain compatible with users and remote nodes still using ZONE_SCOPE. Furthermore, the non-formalized scope value 0 has always been permitted for use during lookup, with the same meaning as ZONE_SCOPE/CLUSTER_SCOPE. We now permit it even as binding scope, but for compatibility reasons we choose to not change the value of TIPC_CLUSTER_SCOPE.

These pernet_operations register and unregister nf hooks, /proc entries, sysctl, percpu statistics. There are several global lists, and the only list modified without exclusive locks is ip_vs_conn_tab in ip_vs_conn_flush(). We iterate the list and force the timers expire at the moment. Since there were possible several timer expirations before this patch, and since they are safe, the patch does not invent new parallelism of their destruction.
