      nvme-rdma: add DELETING queue flag · e89ca58f
      Sagi Grimberg authored
      When we get a surprise disconnect from the target we queue a periodic
      reconnect (which is the sane thing to do...).
      We only move the queues out of CONNECTED when we retry to reconnect (after
      10 seconds in the default case) but we stop the blk queues immediately
      so we are not bothered with traffic from now on. If delete() is kicking
      off in this period the queues are still in CONNECTED state.
      Part of the delete sequence is trying to issue ctrl shutdown if the
      admin queue is CONNECTED (which it is!). This request is issued but
      stuck in blk-mq waiting for the queues to start again. This might be
      the one preventing us from forward progress...
      The patch separates the queue flags to CONNECTED and DELETING. Now we
      will move out of CONNECTED as soon as error recovery kicks in (before
      stopping the queues) and DELETING is on when we start the queue deletion.

      random: Fix crashes with sparse node ids · dd0f0cf5
      Michael Ellerman authored
      On a system with sparse node ids, eg. a powerpc system with 4 nodes
      numbered like so:
        node   0: [mem 0x0000000000000000-0x00000007ffffffff]
        node   1: [mem 0x0000000800000000-0x0000000fffffffff]
        node  16: [mem 0x0000001000000000-0x00000017ffffffff]
        node  17: [mem 0x0000001800000000-0x0000001fffffffff]
      The code in rand_initialize() will allocate 4 pointers for the pool
      array, and initialise them correctly.
      However when go to use the pool, in eg. extract_crng(), we use the
      numa_node_id() to index into the array. For the higher numbered node ids
      this leads to random memory corruption, depending on what was kmalloc'ed
      adjacent to the pool array.
      Fix it by using nr_node_ids to size the pool array.
      Fixes: 1e7f583a ("random: make /dev/urandom scalable for silly userspace programs")

         - more aggressive caching when we can rely on close-to-open

         - remove serialisation of O_DIRECT reads and writes
         - optimise several code paths to not flush to disk unnecessarily.
           However allow for the idiosyncracies of pNFS for those layout
           types that need to issue a LAYOUTCOMMIT before the metadata can
           be updated on the server.
         - SUNRPC updates to the client data receive path
         - pNFS/SCSI support RH/Fedora dm-mpath device nodes
         - pNFS files/flexfiles can now use unprivileged ports when
           the generic NFS mount options allow it.
         - Don't use RDMA direct data placement together with data
           integrity or privacy security flavours
         - Remove the RDMA ALLPHYSICAL memory registration mode as
           it has potential security holes.
         - Several layout recall fixes to improve NFSv4.1 protocol
         - Fix an Oops in the pNFS files and flexfiles connection
           setup to the DS
         - Allow retry of operations that used a returned delegation
