[ubuntu/xenial-proposed] dpdk 2.2.0-0ubuntu7 (Accepted)

[Christian Ehrhardt]

dpdk (2.2.0-0ubuntu7) xenial; urgency=medium

  * Increase max_map_count after setting huge pages (LP: #1507921):
    - The default config of 65530 would cause issues as soon as about 64GB or
      more are used as 2M huge pages for dpdk.
    - Increase this value to base+2*#hugepages to avoid issues on huge systems.
  * d/p/ubuntu-backport-[28-32,34-35] backports for stability (LP: #1568838):
     - these will be in the 16.04 dpdk release, delta can then be dropped.
     - 5 fixes that do not change api/behaviour but fix serious issues.
        - 01 f82f705b lpm: fix allocation of an existing object
        - 02 f9bd3342 hash: fix multi-process support
        - 03 1aadacb5 hash: fix allocation of an existing object
        - 04 5d7bfb73 hash: fix race condition at creation
        - 05 fe671356 vfio: fix resource leak
        - 06 356445f9 port: fix ring writer buffer overflow
        - 07 52f7a5ae port: fix burst size mask type
  * d/p/ubuntu-backport-33-vhost-user-add-error-handling-for-fd-1023.patch
     - this will likely be in dpdk release 16.07 and delta can then be dropped.
     - fixes a crash on using fd's >1023 (LP: #1566874)
  * d/p/ubuntu-fix-lpm-use-after-free-and-leak.patch fix lpm_free (LP: #1569375)
     - the old patches had an error freeing a pointer which had no meta data
     - that lead to a crash on any lpm_free call
     - folded into the fix that generally covers the lpm allocation and free
       weaknesses already (also there this particular mistake was added)
