2020-08-13misc: fix error handling in punt_replicateDave Barach1-2/+7
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(...) Type: fix Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: I774ad8f8c1a0633de4cf8ae5530629201c229347 (cherry picked from commit 1adc7e78ad3eb7e800d0ce3ace56f53ab7aebffe)
2019-08-15vlib: copy trace_handle in vlib_buffer_copy/clone() functionsJohn Lo1-4/+0
Since vlib_buffer_copy() and vlib_buffer_clone() both preserve VLIB_BUFFER_IS_TRACED bit in flags field, it should also copy trace_handle which would add minimal overhead. Thus, callers of these functions do not have to call vlib_buffer_copy_trace_flags() to copy trace_handle.

2019-03-28Punt InfraNeale Ranns1-0/+327
A punt/exception path that provides: 1) clients that use the infra 2) clients can create punt reasons 3) clients can register to recieve packets that are punted for a given reason to be sent to the desired node. 4) nodes which punt packets fill in the {reason,protocol} of the buffere (in the meta-data) and send to the new node "punt-dispatch" 5) punt-dispatch sends packets to the registered nodes or drops Change-Id: Ia4f144337f1387cbe585b4f375d0842aefffcde5 Signed-off-by: Neale Ranns <nranns@cisco.com>
