2022-01-17ipsec: IPSec interface correct drop w/ no protectionNeale Ranns3-8/+19
Type: improvement When an IPSec interface is first constructed, the end node of the feature arc is not changed, which means it is interface-output. This means that traffic directed into adjacencies on the link, that do not have protection (w/ an SA), drop like this: ... 00:00:01:111710: ip4-midchain tx_sw_if_index 4 dpo-idx 24 : ipv4 via 0.0.0.0 ipsec0: mtu:9000 next:6 flags:[] stacked-on: [@1]: dpo-drop ip4 flow hash: 0x00000000 00000000: 4500005c000100003f01cb8cac100202010101010800ecf40000000058585858 00000020: 58585858585858585858585858585858585858585858585858585858 00:00:01:111829: local0-output ipsec0 00000000: 4500005c000100003f01cb8cac100202010101010800ecf40000000058585858 00000020: 5858585858585858585858585858585858585858585858585858585858585858 00000040: 58585858585858585858585858585858585858585858585858585858c2cf08c0 00000060: 2a2c103cd0126bd8b03c4ec20ce2bd02dd77b3e3a4f49664 00:00:01:112017: error-drop rx:pg1 00:00:01:112034: drop local0-output: interface is down although that's a drop, no packets should go to local0, and we want all IPvX packets to go through ipX-drop. This change sets the interface's end-arc node to the appropriate drop node when the interface is created, and when the last protection is removed. The resulting drop is: ... 00:00:01:111504: ip4-midchain tx_sw_if_index 4 dpo-idx 24 : ipv4 via 0.0.0.0 ipsec0: mtu:9000 next:0 flags:[] stacked-on: [@1]: dpo-drop ip4 flow hash: 0x00000000 00000000: 4500005c000100003f01cb8cac100202010101010800ecf40000000058585858 00000020: 58585858585858585858585858585858585858585858585858585858 00:00:01:111533: ip4-drop ICMP: 172.16.2.2 -> 1.1.1.1 tos 0x00, ttl 63, length 92, checksum 0xcb8c dscp CS0 ecn NON_ECN fragment id 0x0001 ICMP echo_request checksum 0xecf4 id 0 00:00:01:111620: error-drop rx:pg1 00:00:01:111640: drop null-node: blackholed packets Signed-off-by: Neale Ranns <neale@graphiant.com> Change-Id: I7e7de23c541d9f1210a05e6984a688f1f821a155

2022-01-11linux-cp: Add VPP->Linux synchronizationPim van Pelt9-167/+743
Part 1 -- notes in https://ipng.ch/s/articles/2021/08/13/vpp-2.html Add the ability for VPP to copy out (sync) its state from the dataplane to Linux Interface Pairs, when they exist. Gated by a configuration flag (linux-cp { lcp-sync }), and by a CLI option to toggle on/off, synchronize the following events: - Interface state changes - Interface MTU changes - Interface IPv4/IPv6 address add/deletion In VPP, subints can have any link state and MTU, orthogonal to their phy. In Linux, setting admin-down on a phy forces its children to be down as well. Also, in Linux, MTU of children must not exceed that of the phy. Add a state synchronizer which walks over phy+subints to ensure Linux and VPP end up in the same consistent state. Part 2 -- notes in https://ipng.ch/s/articles/2021/08/15/vpp-3.html Add the ability for VPP to autocreate sub-interfaces of existing Linux Interface pairs. Gated by a configuration flag (linux-cp { lcp-auto-subint }), and by a CLI option to toggle on/off, synchronize the following event: - Sub-interface creation (dot1q, dot1ad, QinQ and QinAD) A few other changes: - Add two functions into netlink.[ch] to delete ip4 and ip6 addresses. - Remove a spurious logline (printing MTU) in netlink.c. - Resolve a TODO around vnet_sw_interface_supports_addressing() Type: improvement Signed-off-by: Pim van Pelt <pim@ipng.nl> Change-Id: I34fc070e80af4013be58d7a8cbf64296cc760e4e Signed-off-by: Pim van Pelt <pim@ipng.nl>

2022-01-10session: deschedule sessions with no data to sendFlorin Coras3-3/+26
This ensures the scheduler always tracks sessions that are descheduled, i.e., do not have events in the old io events list. When app retries to send, clear descheduled flag and potentially the pacer. Consequently, transports no longer need to reset the pacer when sessions are rescheduled after a long app tx pause. This also fixes a tcp bug whereby the pacer was reset too often when snd_una was equal to snd_nxt as there was no way to distinguish betwen app tx breaks and congestion.
