2021-05-01vlib: refactor trajectory trace debug featureBenoît Ganne1-1/+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.

2020-11-13ethernet: mac must support 64-bits loadsBenoît Ganne1-2/+2
ethernet dataplane loads MAC addresses as 64-bits loads for efficiency. We must make sure it is valid, especially for the vector of secondary MACs. Type: fix Change-Id: I851e319b8a973c154e85ff9f05f3b8e385939788 Signed-off-by: Benoît Ganne <bganne@cisco.com>

2020-04-26dhcp: fix dhcp proxy behavior for qinq and dot1q subinterfacesStanislav Zaikin1-7/+29
Previous behavior worked only when subinterface ID matches with dot1q tag and doesn't work at all in QinQ case. In this patch I'm checking how subinterface is configured. Type: fix Signed-off-by: Stanislav Zaikin <zstaseg@gmail.com> Change-Id: I7a662a0442fdc8e68aba5d6f469f3b1139a4bc2d
2020-04-08misc: check return values from vlib_buffer_copy(...)Dave Barach1-0/+7
vlib_buffer_copy(...) returns NULL if the system is temporarily out of buffers. This is NOT correct. Please don't be this person: c0 = vlib_buffer_copy (vm, p0); ci0 = vlib_get_buffer_index (vm, c0); Type: fix Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: Ic25ef58965871ea5d2b40904df9506803f69e47e
2019-10-25dhcp: fix crash on unicast renewal sendNeale Ranns1-160/+194
Type: fix - when the addresses were learnt a copy of the client was sent to the main thread, this meant the unicast adjacecny was saved on the copy not on the original. - Add logging. - Improve the proxy-node that hands the clint packets so the DHCP packets are traced. - allow a renewal to configure new address data Change-Id: I6ab0afcccbc4a1cdefdd1b8beeda8fc7ba20ec1f Signed-off-by: Neale Ranns <nranns@cisco.com>
