[ upstream commit 651199c ] Some keys can be reused in between GC function calls. To avoid them being GCed we should not mark them as stale keys and wait for the next GC call to be executed. Signed-off-by: André Martins <andre@cilium.io>
[ upstream commit fe9ca34 ] Signed-off-by: André Martins <andre@cilium.io>
[ upstream commit 0892086 ] Signed-off-by: André Martins <andre@cilium.io>
[ upstream commit ea57e36 ] To prevent bursts of security identities from being deleted in the KVStore, possibly causing Cilium agent to have a high CPU usage due policy calculation, this commit adds a rate limiter for such KVStore deletes. For example, in case there are 1000 identities to GCed, the operator will delete 250 every minute until all 1000 identities are GCed. Signed-off-by: André Martins <andre@cilium.io>
