2020-08-13stats: remove offsets on vpp sideOle Troan1-42/+22
Represent pointers directly in shared memory and require clients to adjust for shared memory segment being mapped at different base address. Deprecated: stat_segment_pointer() / stat_segment_offset() Added: stat_segment_adjust() Bumped the stat segment version to 2. Type: refactor Signed-off-by: Ole Troan <ot@cisco.com> Change-Id: I33e756187b8903b45dcd353e6c1a101b7a4acb79

2020-02-05stats: fix state counter removalVladimir Isaev1-0/+3
Avoid using vec_del1() for directory vector to keep indexes valid all the time. There are state counters for each slave in LACP bond mode which can be dynamically created and removed. Vector index is used to access these counters. But also vec_del1() is used to remove counter from vector. This function changes the index of the last element, so after this we are unable to access ex-last element using old index. As a result it is not possible to add-del-add two interfaces to the LACP bond: DBGvpp# create bond mode lacp BondEthernet0 DBGvpp# create packet-generator interface pg1 DBGvpp# create packet-generator interface pg2 DBGvpp# bond add BondEthernet0 pg1 DBGvpp# bond add BondEthernet0 pg2 DBGvpp# bond del pg1 DBGvpp# bond del pg2 DBGvpp# bond add BondEthernet0 pg1 DBGvpp# bond add BondEthernet0 pg2 bond add: /if/lacp/1/3/partner-state is already register Type: fix Signed-off-by: Vladimir Isaev <visaev@netgate.com> Change-Id: I2c86e13905eefdef6233369cd4ab5c1b53d123bd
2019-08-15stats: refactor header filesDave Barach1-37/+1
Performant stat segment scraping involves caching the results of stat_segment_ls (...) and directly fishing counter data from the shared-memory segment. To do that, we need to publish several things previously hidden, declared in stat_client.c: o stat_client_main_t typedef o stat_segment_access_t typedef o stat_segment_access_start inline function o stat_segment_access_end inline function Type: refactor Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: I3175e3d1f1fd8ea816336a584565179d1972115c

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.

2019-05-22stats: support multiple works for error countersOle Troan1-5/+10
The current code only allowed access to the main thread error counters. That is not so useful for a multi worker instance. No return a vector indexed by thread of counter_t values. Type: fix Change-Id: Ie322c8889c0c8175e1116e71de04a2cf453b9ed7 Signed-off-by: Ole Troan <ot@cisco.com>
