2022-12-05stats: return empty vector rather than NULL if stat_segment_dump_r() is run ↵Andrew Yourtchenko1-0/+9
on an empty vector from ls The return value in this function is initialized with 0, so if a vector of length 0 is passed to stat_segment_dump_r, then this return value is never populated, resulting in inability to distinguish between a successful dump of an empty vector and an error. Solution: call vec_alloc(). As a side effect might get some trivial speed-up. Type: fix Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com> Change-Id: I33fefd801df457152e9ec257742305182e91f339
2022-11-29stats: fix the memory leak in stat_client.cAndrew Yourtchenko1-0/+2
The issue can be reproduced by running "vpp_get_stats tightpoll" The root cause is that the control flow discards the "result" struct being prepared, along with pointer its allocated name. This results in a memory leak. Type: fix Change-Id: Ibf884e92314f19b983a0159fc1257b3fa0110443 Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>

2021-05-04stats: adding symlinks for nodes and interfaces in the stat segmentArthur de Kerhor1-7/+48
A given interface counter (e.g rx) can be accessed via /interfaces/<interface_name>/<counter_name>. Same goes with nodes: /nodes/<node_name>/<counter_name> As interfaces may contain '/' in their names, these are replaced by '_' in symlinks Also added 2 tests for the stat segment Type: feature Signed-off-by: Arthur de Kerhor <arthurdekerhor@gmail.com> Change-Id: I27da252e7b3dc177815616ca46b5c200a456bf0f Signed-off-by: Ole Troan <ot@cisco.com>
2020-10-21stats: missing dimension in stat_set_simple_counterOle Troan1-6/+18
A simple counter is a two dimensional array by threads and counter index. 28017 introduced an error missing the first dimension. If a vector is updated at the same time as a client reads, an invalid pointer my result. This will be caught by the optimistic locking after copying out the data, but if following a pointer outside of the stat segment then the stat client would crash. Add suitable boundary checks for access to stat memory segment.

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
