Subject: [dpdk-dev] [PATCH] hash: fix incorrect free slot check
Date: Tue, 4 Oct 2016 08:16:34 +0100 [thread overview]
Message-ID: <1475565394-184188-1-git-send-email-pablo.de.lara.guarch@intel.com> (raw)
In function rte_hash_cuckoo_insert_mw_tm, while looking for
an empty slot, only the first entry in the bucket was being checked,
as key_idx array was not being iterated.
Fixes: 5fc74c2e146d ("hash: check if slot is empty with key index")
Reported-by: Bruce Richardson <bruce.richardson@intel.com>
