Subject: [PATCH] net/enic: fix crash when freeing 0 packet to mempool
[ upstream commit f7a58af502e08368a267886535367f205d4a5de6 ]
Occasionally, the amount of packets to free from the work queue ends
perfectly on a boundary to have nb_free = 0 and pool = 0. This causes
a segfault as follows:
(gdb) bt
#0 rte_mempool_default_cache
#1 rte_mempool_put_bulk (n=0, obj_table=0x7f10deff2530, mp=0x0)
#2 enic_free_wq_bufs (wq=wq@entry=0x7efabffcd5b0,
completed_index=completed_index@entry=33)
#3 0x00007f11e9c86e17 in enic_cleanup_wq (enic=<optimized out>,
wq=wq@entry=0x7efabffcd5b0)
at /usr/src/debug/openvswitch-2.6.1/dpdk-16.11/drivers/net/enic/enic_rxtx.c:442
#4 0x00007f11e9c86e5f in enic_xmit_pkts (tx_queue=0x7efabffcd5b0,
tx_pkts=0x7f10deffb1a8, nb_pkts=<optimized out>)
at /usr/src/debug/openvswitch-2.6.1/dpdk-16.11/drivers/net/enic/enic_rxtx.c:470
#5 0x00007f11e9e147ad in rte_eth_tx_burst (nb_pkts=<optimized out>,
tx_pkts=0x7f10deffb1a8, queue_id=0, port_id=<optimized out>)
This commit makes the enic wq driver match other drivers who call the
bulk free, by checking that there are actual packets to free.
