ASCII art diagrams are well suited for presenting the topology that a test uses while being easy to embed directly in the test file iteslf. They make the information very easy to grasp even for simple topologies, and for more complex ones they are almost essential, as figuring out the interconnects from the script itself proves to be difficult. Therefore state the requirement for topology ASCII art in README. Signed-off-by:

Add a GRE-tunneling test such that there are two tunnels involved, with a multipath route listing both as next hops. Similarly to router_multipath.sh, test that the distribution of traffic to the tunnels honors the configured weights. Signed-off-by:

The function simple_if_init() does two things: it creates a VRF, then moves an interface into this VRF and configures addresses. The latter comes in handy when adding more interfaces into a VRF later on. The situation is similar for simple_if_fini(). Therefore split the interface remastering and address de/initialization logic to a new pair of helpers __simple_if_init() / __simple_if_fini(), and defer to these helpers from simple_if_init() and simple_if_fini().

It looks like the prior VLA removal, commit b16520f7 ("net/tls: Remove VLA usage"), and a new VLA addition, commit c46234eb ("tls: RX path for ktls"), passed in the night. This removes the newly added VLA, which happens to have its bounds based on the same max value. Signed-off-by:

The IP addresses of tunnel endpoint at H3 are set at the VLAN device $h3.555. Therefore when test_gretap_untagged_egress() sets vlan 555 to egress untagged at $swp3, $h3's rp_filter rejects these packets. The test then spuriously fails. Therefore turn off net.ipv4.conf.{all, $h3}.rp_filter. Fixes: 9c7c8a82 ("selftests: forwarding: mirror_gre_vlan_bridge_1q: Add more tests") Signed-off-by: -

In the quest to remove all stack VLA usage from the kernel[1], this allocates the values buffer during the callback instead of putting it on the stack. [1] https://lkml.kernel.org/r/CA+55aFzCG-zNmZwX4A2FQpadafLfEzK6CC=qPXydAacU1RqZWA@mail.gmail.comSigned-off-by:

Jakub Kicinski says: ==================== net: sched: support replay of filter offload when binding to block This series from John adds the ability to replay filter offload requests when new offload callback is being registered on a TC block. This is most likely to take place for shared blocks today, when a block which already has rules is bound to another interface. Prior to this patch set if any of the rules were offloaded the block bind would fail. A new tcf_proto_op is added to generate a filter-specific offload request. The new 'offload' op is supporting extack from day 0, hence we need to propagate extack to .ndo_setup_tc TC_BLOCK_BIND/TC_BLOCK_UNBIND and through tcf_block_cb_register() to tcf_block_playback_offloads(). The immediate use of this patch set is to simplify life of drivers which require duplicating rules when sharing blocks. Switch drivers (mlxsw) can bind ports to rule lists dynamically, NIC drivers generally don't have that ability and need the rules to be duplicated for each ingress they match on. In code terms this means that switch drivers don't register multiple callbacks for each port. NIC drivers do, and get a separate request and hance rule per-port, as if the block was not shared. The registration fails today, however, if some rules were already present. As John notes in description of patch 7, drivers which register multiple callbacks to shared blocks will likely need to flush the rules on block unbind. This set makes the core not only replay the the offload add requests but also offload remove requests when callback is unregistered. v2: - name parameters in patch 2; - use unsigned int instead of u32 for in_hw_coun; - improve extack message in patch 7. ==================== Signed-off-by: -

Call the reoffload tcf_proto_op on all tcf_proto nodes in all chains of a block when a callback tries to register to a block that already has offloaded rules. If all existing rules cannot be offloaded then the registration is rejected. This replaces the previous policy of rejecting such callback registration outright. On unregistration of a callback, the rules are flushed for that given cb. The implementation of block sharing in the NFP driver, for example, duplicates shared rules to all devs bound to a block. This meant that rules could still exist in hw even after a device is unbound from a block (assuming the block still remains active). Signed-off-by:

Add the offload tcf_proto_op in cls_bpf to generate an offload message for each bpf prog in the given tcf_proto. Call the specified callback with this new offload message. The function only returns an error if the callback rejects adding a 'hardware only' prog. A prog contains a flag to indicate if it is in hardware or not. To ensure the offload function properly maintains this flag, keep a reference counter for the number of instances of the prog that are in hardware. Only update the flag when this counter changes from or to 0. Signed-off-by:

Create a new tcf_proto_op called 'reoffload' that generates a new offload message for each node in a tcf_proto. Pointers to the tcf_proto and whether the offload request is to add or delete the node are included. Also included is a callback function to send the offload message to and the option of priv data to go with the cb. Signed-off-by:

The newer SoC manuals do have RPADIR documented, though with somewhat different layout -- update the *enum* according to these manuals... Signed-off-by:

Commit 5691484d ("net: ip6_gre: Fix headroom request in ip6erspan_tunnel_xmit()") and commit 01b8d064 ("net: ip6_gre: Request headroom in __gre6_xmit()") fix problems in reserving headroom in the packets tunneled through ip6gre/tap and ip6erspan netdevices. These two patches included snippets that reproduced the issues. This patch elevates the snippets to a full-fledged test case. Suggested-by:
