Subject: [dpdk-dev] [PATCH v2] net/bonding: fix race condition
Date: Wed, 25 Jul 2018 10:39:40 +0100 [thread overview]
Message-ID: <1532511580-2631-1-git-send-email-radu.nicolau@intel.com> (raw)
In-Reply-To: <1532080957-26940-1-git-send-email-radu.nicolau@intel.com>
Race condition can appear in the bond_mode_8023ad_periodic_cb()
callback when bonding port is stopped, reconfigured and restarted.
Re-ordered calls in bond_ethdev_start() to have callback alarm set
after slave ports are reconfigured.
Fixes: 2efb58cbab6e ("bond: new link bonding library")
Cc: stable@dpdk.org
