2021-11-16ip6: set local flag on outbound echo replyMatthew Smith1-0/+4
Type: fix When VPP generates an ICMP echo reply in response to an incoming echo request to a local address, set VNET_BUFFER_F_LOCALLY_ORIGINATED on the buffer. It will prevent ip6-rewrite from decrementing the hop limit. Outbound IPv4 echo replies also get this flag set.

2021-08-14ip: Fix crash in ip address add on sub-int without exact-matchPim van Pelt2-12/+6
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

2021-05-01vlib: refactor trajectory trace debug featureBenoît Ganne2-3/+0
trajectory trace has been broken for a while because we used to save the buffer trajectory in a vector pointed to in opaque2. This does not work well when opaque2 is copied (eg. because of a clone) as 2 buffers end up sharing the same vector. This dedicates a full cacheline in the buffer metadata instead when trajectory is compiled in. No dynamic allocation, no sharing, no tears.

2021-02-15vlib: refactor checksum offload supportMohsin Kazmi4-38/+37
Type: refactor This patch refactors the offload flags in vlib_buffer_t. There are two main reasons behind this refactoring. First, offload flags are insufficient to represent outer and inner headers offloads. Second, room for these flags in first cacheline of vlib_buffer_t is also limited. This patch introduces a generic offload flag in first cacheline. And detailed offload flags in 2nd cacheline of the structure for performance optimization.
