2023-04-12ip: punt socket - take the tags in Ethernet header into considerationAndrew Yourtchenko1-1/+2
The punt socket code rewinds the current_data pointer by sizeof (ethernet_header_t), which is incorrect if the header is tagged - resulting in truncated destination MAC address. Use ethernet_buffer_header_size() instead, which takes tags into account. Also add the unittest that verifies the issue and the fix.

2021-05-01vlib: refactor trajectory trace debug featureBenoît Ganne1-2/+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.

2020-11-09vlib: fix trace number accountingBenoît Ganne1-2/+4
When using classifier to filter traces, not all packets will be traced. In that case, we should only count traced packets. Type: fix Change-Id: I87d1e217b580ebff8c6ade7860eb43950420ae78 Signed-off-by: Benoît Ganne <bganne@cisco.com>

2020-04-09misc: fix error handling in punt_replicateDave Barach1-0/+1
If vlib_buffer_clone (...) fails due to a buffer allocation error, update *n_dispatched with the actual number of clones, not the requested number of clones. Punt_replicate(...) should not set *to_next[0] = bi0. The original buffer is enqueued separately in punt_dispatch_node(...)

2019-07-05sctp: move to plugins, disabled by defaultFlorin Coras1-1/+0
Removed sctp buffer metadata from vnet/buffer.h, added it to the plugin. Add registration APIs for plugin-based vlib_buffer_opaque / opaque2 decoders, used by "pcap dispatch trace ..." for display in the wireshark dissector. Type:refactor Not actively maintained.

2019-05-28Punt: socket register for exception dispatched/punted packets based on reasonNeale Ranns1-0/+587
- add to the Punt API to allow different descriptions of the desired packets: UDP or exceptions - move the punt nodes into punt_node.c - improve tests (test that the correct packets are punted to the registered socket) Change-Id: I1a133dec88106874993cba1f5a439cd26b2fef72 Signed-off-by: Neale Ranns <nranns@cisco.com>
