2018-06-13Stat segment / client: show run" works nowDave Barach1-11/+19
Seems to have minimal-to-zero performance consequences. Data appears accurate: result match the debug CLI output. Checked at low rates, 27 MPPS sprayed across two worker threads. Change-Id: I09ede5150b88a91547feeee448a2854997613004 Signed-off-by: Dave Barach <dave@barachs.net>

2018-01-09api: refactor vlibmemoryFlorin Coras1-0/+54
- separate client/server code for both memory and socket apis - separate memory api code from generic vlib api code - move unix_shared_memory_fifo to svm and rename to svm_fifo_t - overall declutter Change-Id: I90cdd98ff74d0787d58825b914b0f1eafcfa4dc2 Signed-off-by: Florin Coras <fcoras@cisco.com>
2017-07-13VPP-895 multi-thread: fix vpp crash on show runtimeIgor Mikhailov (imichail)1-0/+29
In multi-threaded model (e.g. 1 main and 1 worker threads), after an ethernet interface is deleted (e.g. vhost-user interface), 'show runtime' command produces garbled output and sometimes leads to vpp crash. The reason is because vlib_node_rename() frees and reallocates node's 'n->name' vector, however the change is not propagated into copies of the node on worker threads.

traffic (VPP-892) When stacking DPOs the VLIB graph is also updated to add the edge between the nodes, if this edge does not yet exist. This addition should be done with the workers stopped.

2017-06-09Implement sack based tcp loss recovery (RFC 6675)Florin Coras1-0/+1
- refactor existing congestion control code (RFC 6582/5681). Handling of ack feedback now consists of: ack parsing, cc event detection, event handling, congestion control update - extend sack scoreboard to support sack based retransmissions - basic implementation of Eifel detection algorithm (RFC 3522) for detecting spurious retransmissions - actually initialize the per-thread frame freelist hash tables - increase worker stack size to 2mb - fix session queue node out-of-buffer handling - ensure that the local buffer cache vec_len matches reality - avoid 2x spurious event requeues when short of buffers - count out-of-buffer events - make the builtin server thread-safe - fix bihash template threading issue: need to paint -1 across uninitialized working_copy_length vector elements (via rebase from master) Change-Id: I646cb9f1add9a67d08f4a87badbcb117980ebfc4 Signed-off-by: Florin Coras <fcoras@cisco.com> Signed-off-by: Dave Barach <dbarach@cisco.com>
2017-04-06Use thread local storage for thread indexDamjan Marion1-1/+1
This patch deprecates stack-based thread identification, Also removes requirement that thread stacks are adjacent. Finally, possibly annoying for some folks, it renames all occurences of cpu_index and cpu_number with thread index. Using word "cpu" is misleading here as thread can be migrated ti different CPU, and also it is not related to linux cpu index.
