2022-10-17vlib: Counter free needs to NULL the allocated counter vectorNeale Ranns1-2/+8
otherwise the next time the counter is validated this is dangling. Type: fix Fixes: 58fd481d73 Signed-off-by: Neale Ranns <neale@graphiant.com> Change-Id: Ifa8d5ff27175cf6dfb30cbf023fa3251fe5c780e

2021-02-04vlib: increase the stats epoch only when necessaryMiklos Tirpak1-16/+35
When the counter vectors are validated and they are already long enough to fit the given index in memory, there is no need to increase the stats segment epoch. In this case, the counter vectors do not change as a result of the validation. This optimization is necessary for the case when the configuration is changed at multiple thousands per second rate. The counter vectors grow at the beginning and their size stabilizes after a while. Without this improvement, it can still take several seconds for a stats reader to succeed.

2021-01-15vlib: fix counter_will_expand predictionMiklos Tirpak1-6/+3
vlib_validate_combined_counter_will_expand() was calling _vec_resize_will_expand() with wrong arguments, which resulted in false return value. Apart from the initial call, it never indicated a vector resize. The callers relying on this function did not perform a barrier sync because of the wrong prediction even if the vector got extended by a subsequent vlib_validate_combined_counter() call. The fix introduces a new, simplified macro that is easier to call. vec_resize_will_expand() accepts the same arguments as vec_resize().

2019-05-22stats: support multiple works for error countersOle Troan1-13/+1
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>
