2021-10-14nat: static mappings in flow hashKlement Sekera10-238/+162
Put static mappings in flow hash, drop existing hash tables used for static mappings. Drop refcount variables and use hash table as a single point of truth. Allow creating a static mapping conflicting with dynamic mapping, which will take precedence after dynamic mapping is freed, so that the existing flow can finish transferring data.

2021-05-01vlib: refactor trajectory trace debug featureBenoît Ganne1-7/+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.

2021-04-28nat: fix byte order on ipfix message fieldsMatthew Smith1-3/+6
Type: fix The code for quota exceeded events is a u32 and was being copied into ipfix packets in host byte order. Same for the limit field. Swap the order before copying into packet buffer. This change was applied once before but had to be reverted. This was because between the time the change was uploaded/reviewed and the time it was merged, a different patch was merged which activated a NAT ipfix unit test that had formerly only been run as part of the extended tests. The test was expecting the values to be in host byte order so it failed with this patch applied. This time around, that test has also been updated to expect network byte order.

2020-11-12nat: use table ID for nat44 ipfix session eventsMatthew Smith2-7/+10
Type: fix IPfix messages about NAT44 session create/delete were being populated with the FIB table index instead of the table ID. The table ID is the correct identifier to report externally (NAT64 IPfix messages for BIB and session create/delete use table ID, as does NAT syslogging). Convert the table index to an ID before adding it to the IPfix NAT44 session create/delete message data.
