2021-08-18vhost: interrupt mode support with mqSteven Luong3-138/+209
vhost interrupt mode support with mq does not work when coalesce frame is not configured to 0. When packed-ring is configured, we were also setting the wrong flag for want-interrupt. No need to trigger an interrupt to RX infra if there is at least one queue in the same thread that is doing polling.

2021-08-14ip: Fix crash in ip address add on sub-int without exact-matchPim van Pelt4-12/+32
Type: fix Creating a sub-int without exact-match set, and subsequently adding an IPv4 or IPv6 address will crash VPP. This fix catches this situation and refuses to allow the caller to add an IPv4 or IPv6 address on an ethernet sub-int that does not have exact-match set. TESTED: Before this change, the following crashes VPP: ``` DBGvpp# cre sub TenGigabitEthernet3/0/0 1 dot1q 10 TenGigabitEthernet3/0/0.1 DBGvpp# set interface ip address TenGigabitEthernet3/0/0.1 2001:db8::1/64 <crash> ``` After the change, VPP refuses to act: ``` DBGvpp# cre sub TenGigabitEthernet3/0/0 1 dot1q 10 TenGigabitEthernet3/0/0.1 DBGvpp# set interface ip address TenGigabitEthernet3/0/0.1 192.0.2.1/30 set interface ip address: sub-interface without exact-match doesn't support IP addressing DBGvpp# set interface ip address TenGigabitEthernet3/0/0.1 2001:db8:1/64 set interface ip address: sub-interface without exact-match doesn't support IP addressing ``` Signed-off-by: Pim van Pelt <pim@ipng.nl> Change-Id: I42997db314225cd186ebb54013b5717ace7f7bd6

2021-07-28gre: set proper fib index for unnumbered interfaces, unset fib index before ↵Stanislav Zaikin5-7/+67
forwarding gre payload This commit introduces 2 fixes: 1) After GRE decapsulation sw_if_index[VLIB_TX] is set as fib index of GRE tunnel. But since GRE tunnel can work on v4 endpoints and have v6 payload, we need to reset it. In case we get IPv6 packet inside IPv4 GRE tunnel (or vice-versa) fib index can be (and usually is) invalid. 2) Check that ip-table and ip6-table are the same when setting interface as an unnumbered one. Also, fix for the pipe test include setting the right unnumbered interface for the pipes Type: fix Signed-off-by: Stanislav Zaikin <zstaseg@gmail.com> Change-Id: Id13d239cfdd21e0db6b1c9725f01c40d4af4d800

2021-07-23session vcl: support abstract sockets for app nsFlorin Coras4-16/+132
App namespaces can now be associated to a linux ip netns, e.g.: app ns add id <ns_id> secret <n> sw_if_index <n> netns <netns> If session layer's app sock api is enabled, this triggers the creation of an abstract listening socket in the netns that has been configured. For the example above that would be @vpp/session/<ns_id>. Consequently, vcl, or other apps attaching to vpp, can connect to said abstract socket from an ip netns without the need to share unix domain socket files. In particular, for vcl it's enough to set app-socket-api to @vpp/session/<ns_id> in the conf file.

2021-07-15ip-neighbor: GARP sent to bogus ip addressSteven Luong1-2/+2
The function ip4_neighbor_advertise may be called with NULL addr. In that case, it looks up addr from fib by calling fib_sas4_get which returns true or false to indicate whether there is an ip address associated with the interface or not. But the caller to fib_sas4_get does not check the return code and blindly assumes there is always an ip address associated with the interface. As a result, it ends up sending GARP to the bogus ip address if there is no ip address associated with the interface.
