This patch is to implement Receiver-Side Procedures for the Re-configuration Response Parameter in rfc6525 section 5.2.7. sctp_process_strreset_resp would process the response for any kind of reconf request, and the stream reconf is applied only when the response result is success. Signed-off-by:

This patch is to implement Receiver-Side Procedures for the Add Incoming Streams Request Parameter described in rfc6525 section 5.2.6. It is also to fix that it shouldn't have add streams when sending addstrm in request, as the process in peer will handle it by sending a addstrm out request back. Signed-off-by:

While running a single stream UDPv6 test, we observed that amount of CPU spent in NET_RX softirq was much greater than UDPv4 for an equivalent receive rate. The test here was run on an ARM64 based Android system. On further analysis with perf, we found that UDPv6 was spending significant time in the statistics netfilter targets which did socket lookup per packet. These statistics rules perform a lookup when there is no socket associated with the skb. Since there are multiple instances of these rules based on UID, there will be equal number of lookups per skb. By introducing early demux for UDPv6, we avoid the redundant lookups. This also helped to improve the performance (800Mbps -> 870Mbps) on a CPU limited system in a single stream UDPv6 receive test with 1450 byte sized datagrams using iperf. v1->v2: Use IPv6 cookie to validate dst instead of 0 as suggested by Eric Signed-off-by:

The original reason [1] for having hidden qdiscs (potential scalability issues in qdisc_match_from_root() with single linked list in case of large amount of qdiscs) has been invalidated by 59cc1f61 ("net: sched: convert qdisc linked list to hashtable"). This allows us for bringing more clarity and determinism into the dump by making default pfifo qdiscs visible. We're not turning this on by default though, at it was deemed [2] too intrusive / unnecessary change of default behavior towards userspace. Instead, TCA_DUMP_INVISIBLE netlink attribute is introduced, which allows applications to request complete qdisc hierarchy dump, including the ones that have always been implicit/invisible. Singleton noop_qdisc stays invisible, as teaching the whole infrastructure about singletons would require quite some surgery with very little gain (seeing no qdisc or seeing noop qdisc in the dump is probably setting the same user expectation).

Jiri Pirko says: ==================== ipv4: fib: FIB notifications cleanup Ido says: The first patch moves the core FIB notification code to a separate file, so that code related to FIB rules is placed in fib_rules.c and not fib_trie.c.

Most of the code concerned with the FIB notification chain currently resides in fib_trie.c, but this isn't really appropriate, as the FIB notification chain is also used for FIB rules. Therefore, it makes sense to move the common FIB notification code to a separate file and have it export the relevant functions, which can be invoked by its different users (e.g., fib_trie.c, fib_rules.c).

Jiri Pirko says: ==================== mlxsw: Preparations for VRF offload Ido says: This patchset aims to prepare the mlxsw driver for VRF offload. The follow-up patchsets that introduce VRF support can be found here: https://github.com/idosch/linux/tree/idosch-next The first four patches are mainly concerned with the netdevice notification block. There are no functional changes, but merely restructuring to more easily integrate VRF enslavement. Patches 5-10 remove various assumptions throughout the code about a single virtual router (VR) and also restructure the internal data structures to more accurately represent the device's operation. ==================== Signed-off-by:

When the abort mechanism is invoked it binds the first virtual router (VR) to an LPM tree and inserts a default route to direct packets to the CPU. With VRFs, we can have router interfaces (RIFs) bound to multiple VRs, so we need to make sure packets are trapped from all VRs and not just the first one. Upon abort invocation, bind all active VRs to the same LPM tree and insert a default route in each. Signed-off-by:

Up until now we implicitly associated all the router interfaces (RIFs) with the first virtual router (VR). This must be changed in order to enable VRF offload. Otherwise, a packet received via a VRF slave would do a FIB lookup in the same table used by other VRFs. Instead, bind the RIF to a VR according to the table where FIB lookup should be performed for packets received via the RIF. Currently, we only care about the MAIN and LOCAL tables (which we squash together). Signed-off-by:

A virtual router (VR) is an entity within the device to which routing tables and interfaces can be bound to. It can be used to implement VRFs. In the initial implementation we associated the VR with a specific protocol (e.g., IPv4) and an LPM tree. However, this isn't really accurate, as the same VR can be used for both IPv4 and IPv6 traffic, by binding a different LPM tree to a {VR, Proto} pair. This patch aims to restructure the VR code according to the above logic, so that VRs are more accurately represented by the driver's data structures. The main motivation behind this change is to prepare the driver for VRF offload. Signed-off-by: -

When looking for a new LPM tree we should always consider all the unused trees. It doesn't matter if the new tree is required due to changes in currently used prefixes inside an existing routing table or because a route was inserted into an empty table. Both cases are functionally identical and therefore should be treated the same. When looking for a new LPM tree, consider all unused trees and don't reserve trees for specific cases. Signed-off-by:

The inetaddr notification block is currently implemented in the main driver file, but this isn't really appropriate, as it mainly creates and destroys router interfaces (RIFs) which belong with the rest of the router code. This will become even more apparent later on when we'll need to bind these RIFs to virtual routers according to the VRF's table. Structure the driver better and prevent unnecessary function exports by moving the RIF related code with the rest of the router code. Signed-off-by:

Allow 'unreachable', 'blackhole' and 'prohibit' route types to be programmed into the device by sending any packet hitting them to the CPU. This is needed so that users will be able to program a default route into the VRF's table, thereby preventing lookup from leaking to other tables. Audit the code paths to make sure we don't rely on the presence of a nexthop netdev, as it doesn't exist for above mentioned route types. Signed-off-by:

We only use the RIF reference count to determine when the last IP address was removed, but instead we can just test 'in_dev->ifa_list'. Signed-off-by:

When a VLAN device is configured on top of a LAG device (f.e., bond0.10), a vPort is created on top of each of the LAG's slaves and its 'dev' pointer is set to the VLAN device. This is in contrast to the implicit PVID vPort (representing 'bond0'), whose 'dev' pointer keeps pointing to the port netdev itself (f.e., 'sw1p1'). Make both cases consistent by setting their 'dev' pointer to the actual netdev they represent. Either the LAG device itself (in the case of the PVID vPort) or the VLAN device on top of it. This will later allow us to more easily understand for which netdev we should create the router interface (RIF) upon enslavement to a VRF master. Signed-off-by:

When an upper device is configured on top of a vPort we make sure it's a bridge master during PRECHANGEUPPER and fail otherwise. Therefore, when CHANGEUPPER is later received we don't bother checking the upper's type. Make the code more extendable in preparation for VRF uppers, by checking the upper's type. Signed-off-by:

We're going to allow bridges stacked on top of port netdevs to be enslaved to a VRF, but for now, only VLAN uppers of the VLAN-aware bridge are supported. Sanitize any other bridge upper. This is consistent with the way we sanitize port netdevs' uppers. Signed-off-by:

In original driver was implemented support for half- and full-duplex modes, but it was not enabled. Instead of it ks8851_rx_1msg method always returns "true" that means "full-duplex" mode.

Mahesh Bandewar says: ==================== bonding: winter cleanup Few cleanup patches that I have accumulated over some time now. (a) First two patches are basically to move the work-queue initialization from every ndo_open / bond_open operation to once at the beginning while port creation. Work-queue initialization is an unnecessary operation for every 'ifup' operation. However we have some mode-specific work-queues and mode can change anytime after port creation. So the second patch is to ensure the correct work-handler is called based on the mode. (b) Third patch is simple and straightforward that removes hard-coded value that was added into the initial commit and replaces it with the default value configured. (c) The final patch in the series removes the unimplemented "port-moved" state from the LACP state machine. This state is defined but never set so removing from the state machine logic makes code little cleaner. (d) Reduce scope of some global variables to local. Note: None of these patches are making any functional changes. ==================== Signed-off-by: -
