Subject: [PATCH] crypto/aesni_mb: fix HMAC supported key sizes

[ upstream commit cefa431162fcef7f1ef0804beb25d7a9883fc54a ]

For HMAC algorithms (MD5-HMAC, SHAx-HMAC), the supported
key sizes are not a fixed value, but a range between
1 and the block size.

Subject: [PATCH] test/bonding: fix memory corruptions

[ upstream commit 8d3708efece06212bde6b1e10b2251931e1e9961 ]

There were double-free problems in some test cases, which will cause
a duplicated mbuf will be added into mempool.  After double-free,
some new allocated mbuf will hold a same address and thus cause the
memory corruption.

Another minor issue is that in some test cases, allocated mbuf will
not be released after test case exits.  Hopefully these leaked mbuf
will be released by the next test case in its setup phase when
stopping the virtual pmd ports, while this do is a memory leak of
the exited test case.

To fix above 2 issues, this patch will do:
1) Release virtual pmd ports' tx queue in the clean up function
   remove_slaves_and_stop_bonded_device() of each test cases.
2) Do not release allocated mbufs for test bursts.  These mbufs
   will be released in remove_slaves_and_stop_bonded_device() when
   test case exits.

Fixes: 92073ef961ee ("bond: unit tests")

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.

Subject: [PATCH] vhost: make page logging atomic

[ backported from upstream commit 897f13a1f726cefdc68762da83f9d2225a85c27e ]

Each dirty page logging operation should be atomic. But it's not
atomic in current implementation. So it's possible that some dirty
pages can't be logged successfully when different threads try to
log different pages into the same byte of the log buffer concurrently.
This patch fixes this issue.

Hi, this patch will cause DPDK PF failing to send messages to kernel VF, and can't get kernel interface in VM.
So I will rework on this issue.
