      net: ipv6: Add IPv6 support to the ping socket. · 6d0bfe22
      Lorenzo Colitti authored
      This adds the ability to send ICMPv6 echo requests without a
      raw socket. The equivalent ability for ICMPv4 was added in
      2011.
      
      Instead of having separate code paths for IPv4 and IPv6, make
      most of the code in net/ipv4/ping.c dual-stack and only add a
      few IPv6-specific bits (like the protocol definition) to a new
      net/ipv6/ping.c. Hopefully this will reduce divergence and/or
      duplication of bugs in the future.
      
      Caveats:
      
      - Setting options via ancillary data (e.g., using IPV6_PKTINFO
        to specify the outgoing interface) is not yet supported.
      - There are no separate security settings for IPv4 and IPv6;
        everything is controlled by /proc/net/ipv4/ping_group_range.
      - The proc interface does not yet display IPv6 ping sockets
        properly.
      
      Tested with a patched copy of ping6 and using raw socket calls.
      Compiles and works with all of CONFIG_IPV6={n,m,y}.

      GFS2: Use single-block reservations for directories · af21ca8e
      Bob Peterson authored
      This patch changes the multi-block allocation code, such that
      directory inodes only get a single block reserved in the bitmap.
      That way, the bitmaps are more tightly packed together, and there
      are fewer spans of free blocks for in-use block reservations.
      This means it takes less time to find a free span of blocks in the
      bitmap, which speeds things up. This increases the performance of
      some workloads by almost 2X. In Nate's mockup.py script (which does
      (1) create dir, (2) create dir in dir, (3) create file in that dir)
      the test executes in 23 steps rather than 43 steps, a 47%
      performance improvement.

      powerpc/pseries: Make 32-bit MSI quirk work on systems lacking firmware support · f1dd1531
      Brian King authored
      Recent commit e61133dd added support
      for a new firmware feature to force an adapter to use 32 bit MSIs.
      However, this firmware is not available for all systems. The hack below
      allows devices needing 32 bit MSIs to work on these systems as well.
      It is careful to only enable this on Gen2 slots, which should limit
      this to configurations where this hack is needed and tested to work.

      be2net: bug fix on returning an invalid nic descriptor · 950e2958
      Wei Yang authored
      In function be_get_nic_desc(), it will go through the descriptor array
      returned from f/w. By comparing the desc_type field, it determines whether
      there is a nic descriptor in the array or not. In the case of no nic
      descriptor, this function should return NULL.
      
      The code may return an invalide descriptor, when there is no nic descriptor
      in the array and the desc_count is less than MAX_RESOURCE_DESC. In this case,
      even there is no nic descriptor, it will still return the lase descriptor
      since the i doesn't equal to MAX_RESOURCE_DESC.
      
      This patch fix this issue by returning the descriptor when find it and return
      NULL for other cases.
