      ppc_asm.h code. However, while adding it in the headers for the ppc32 case,
      it missed out to remove the former definition in the KVM code.

      Add a new parameter to __rbd_refresh_header() through which the
      version of the header object is passed back to the caller.  In most
      cases this isn't needed.  The main motivation is to normalize

      rbd: fixes in rbd_header_from_disk() · ccece235
      Alex Elder authored
      This fixes a few issues in rbd_header_from_disk():
          - There is a check intended to catch overflow, but it's wrong in
            two ways.
      	- First, the type we don't want to overflow is size_t, not
      	  unsigned int, and there is now a SIZE_MAX we can use for
      	  use with that type.
      	- Second, we're allocating the snapshot ids and snapshot
      	  image sizes separately (each has type u64; on disk they
                grouped together as a rbd_image_header_ondisk structure).
      	  So we can use the size of u64 in this overflow check.
          - If there are no snapshots, then there should be no snapshot
            names.  Enforce this, and issue a warning if we encounter a
            header with no snapshots but a non-zero snap_names_len.
          - When saving the snapshot names into the header, be more direct
            in defining the offset in the on-disk structure from which
            they're being copied by using "snap_count" rather than "i"
            in the array index.
          - If an error occurs, the "snapc" and "snap_names" fields are
            freed at the end of the function.  Make those fields be null
            pointers after they're freed, to be explicit that they are
            no longer valid.
          - Finally, move the definition of the local variable "i" to the
            innermost scope in which it's needed.

      rbd: always pass ops array to rbd_req_sync_op() · 913d2fdc
      Alex Elder authored
      All of the callers of rbd_req_sync_op() except one pass a non-null
      "ops" pointer.  The only one that does not is rbd_req_sync_read(),
      which passes CEPH_OSD_OP_READ as its "opcode" and, CEPH_OSD_FLAG_READ
      for "flags".
      
      By allocating the ops array in rbd_req_sync_read() and moving the
      special case code for the null ops pointer into it, it becomes
      clear that much of that code is not even necessary.
      
      In addition, the "opcode" argument to rbd_req_sync_op() is never
      actually used, so get rid of that.

      We drop the lock when calling the ->alloc_msg() con op, which means

      This function's calling convention is very limiting.  In particular,
      we can't return any error other than ENOMEM (and only implicitly),
      which is a problem (see next patch).
      
      Instead, return an normal 0 or error code, and make the skip a pointer
      output parameter.  Drop the useless in_hdr argument (we have the con
      pointer).

      libceph: avoid dropping con mutex before fault · 8636ea67
      Sage Weil authored
      The ceph_fault() function takes the con mutex, so we should avoid
      dropping it before calling it.  This fixes a potential race with
      another thread calling ceph_con_close(), or _open(), or similar (we
      don't reverify con->state after retaking the lock).
      
      Add annotation so that lockdep realizes we will drop the mutex before
      returning.

      libceph: verify state after retaking con lock after dispatch · 7b862e07
      Sage Weil authored
      We drop the con mutex when delivering a message.  When we retake the
      lock, we need to verify we are still in the OPEN state before
      preparing to read the next tag, or else we risk stepping on a
      connection that has been closed.

      This is mostly moot since we are re-using the same ceph_connection,

      libceph: replace connection state bits with states · 8dacc7da
      Sage Weil authored
      Use a simple set of 6 enumerated values for the socket states (CON_STATE_*)
      and use those instead of the state bits.  All of the con->state checks are
      now under the protection of the con mutex, so this is safe.  It also
      simplifies many of the state checks because we can check for anything other
      than the expected state instead of various bits for races we can think of.
      
      This appears to hold up well to stress testing both with and without socket
      failure injection on the server side.

      rbd_req_sync_watch() is only called in one place, and in that place
      it passes rbd_dev->header_name as the value of the "object_name"
      parameter.  This value is available within the function already.
      
      Having the extra parameter leaves the impression the object name
      could take on different values, but it does not.
      
      So get rid of the parameter.  We can always add it back again if
      we find we want to watch some other object in the future.
