2020-05-04fib: midchain adjacency optimisationsNeale Ranns25-605/+822
Type: improvement - inline some common encap fixup functions into the midchain rewrite node so we don't incur the cost of the virtual function call - change the copy 'guess' from ethernet_header (which will never happen) to an ip4 header - add adj-midchain-tx to multiarch sources - don't run adj-midchain-tx as a feature, instead put this node as the adj's next and at the end of the feature arc. - cache the feature arc config index (to save the cache miss going to fetch it) - don't check if features are enabled when taking the arc (since we know they are) the last two changes will also benefit normal adjacencies taking the arc (i.e. for NAT, ACLs, etc) for IPSec: - don't run esp_encrypt as a feature, instead when required insert this node into the adj's next and into the end of the feature arc. this implies that encrypt is always 'the last feature' run, which is symmetric with decrypt always being the first. - esp_encrpyt for tunnels has adj-midchain-tx as next node Change-Id: Ida0af56a704302cf2d7797ded5f118a781e8acb7 Signed-off-by: Neale Ranns <nranns@cisco.com>

2020-05-04misc: binary api fuzz test fixesDave Barach7-9/+10
Add a hook to src/vlibapi/api_shared.c to fuzz (screw up) binary API messages, e.g. by xoring random data into them before processing. We specifically exempt client connection messages, and inband debug CLI messages. We step over msg_id, client index, client context, and sw_if_index. Otherwise, "make test" vectors fail too rapidly to learn anything. The goal is to reduce the number of crashes caused to zero. We're fairly close with this patch. Add vl_msg_api_max_length(void *mp), which returns the maximum plausible length for a binary API message. Use it to hardern vl_api_from_api_to_new_vec(...) which takes an additional argument - message pointer - so it can verify that astr->length is sane. If it's not sane, return a u8 *vector of the form "insane astr->length nnnn\0". Verify array lengths in vl_api_dhcp6_send_client_message_t_handler(...) and vl_api_dhcp6_pd_send_client_message_t_handler(...). Add a fairly effective binary API fuzz hook to the unittest plugin, and modify the "make test" framework.py to pass "api-fuzz { on|off }" to enable API fuzzing: "make API_FUZZ=on TEST=xxx test-debug" or similar Type: improvement Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: I0157267652a163c01553d5267620f719cc6c3bde

2020-04-27virtio: support virtio 1.1 packed ring in vhostSteven Luong8-156/+1604
virtio 1.1 defines a number of new features. Packed ring is among the most notable and important one. It combines used, available, and descripptor rings into one. This patch provides experimental support for packed ring. To avoid regression, when packed ring is configured for the interface, it is branched to a separate RX and TX driver. Non packed ring should continue to perform as it was before. Packed ring is tested using qemu4.2 and ubuntu focal fossa (kernel 5.4.0-12) on the guess VM which supports packed ring. To configure VPP with packed ring, just add the optional keyword "packed" when creating the vhost interface. To bring up the guest VM with packed ring, add "packed=on" in the qemu launch command. To facilitate troubleshooting, also added "verbose" option in show vhost desc CLI to include displaying the indirect descriptors. Known qemu reconnect issue - If VPP is restarted, guest VMs also need to be restarted. The problem is kernel virtio-net-pci keeps track of the previous available and used indices. For virtio 1.0, these indices are in shared memory and qemu can easily copy them to pass to the backend for reconnect. For virio 1.1, these indices are no longer in shared memory. Qemu needs a new mechanism to retrieve them and it is not currently implemented. So when the protocol reconnects, qemu does not have the correct available and used indices to pass to the backend. As a result, after the reconnect, virtio-net-pci is reading the TX ring from the wrong position in the ring, not the same position which the backend is writing. Similar problem exists also in the RX.
