      net: ipv4: emulate READ_ONCE() on ->hdrincl bit-field in raw_sendmsg() · 20b50d79
      Nicolai Stange authored
      Commit 8f659a03 ("net: ipv4: fix for a race condition in
      raw_sendmsg") fixed the issue of possibly inconsistent ->hdrincl handling
      due to concurrent updates by reading this bit-field member into a local
      variable and using the thus stabilized value in subsequent tests.
      
      However, aforementioned commit also adds the (correct) comment that
      
        /* hdrincl should be READ_ONCE(inet->hdrincl)
         * but READ_ONCE() doesn't work with bit fields
         */
      
      because as it stands, the compiler is free to shortcut or even eliminate
      the local variable at its will.
      
      Note that I have not seen anything like this happening in reality and thus,
      the concern is a theoretical one.
      
      However, in order to be on the safe side, emulate a READ_ONCE() on the
      bit-field by doing it on the local 'hdrincl' variable itself:
      
      	int hdrincl = inet->hdrincl;
      	hdrincl = READ_ONCE(hdrincl);
      
      This breaks the chain in the sense that the compiler is not allowed
      to replace subsequent reads from hdrincl with reloads from inet->hdrincl.

      net: caif: use strlcpy() instead of strncpy() · 3dc2fa47

      The compiler require that the input param 'len' of strncpy() should be
      greater than the length of the src string, so that '\0' is copied as
      well. We can just use strlcpy() to avoid this warning.

      Pull rdma fixes from Doug Ledford:
      
       - One line fix to mlx4 error flow (same as mlx5 fix in last pull
         request, just in the mlx4 driver)
      
       - Fix a race condition in the IPoIB driver. This patch is larger than
         just a one line fix, but resolves a race condition in a fairly
         straight forward manner
      
       - Fix a locking issue in the RDMA netlink code. This patch is also
         larger than I would like for a late -rc. It has, however, had a week
         to bake in the rdma tree prior to this pull request
      
       - One line fix to fix granting remote machine access to memory that
         they don't need and shouldn't have
      
       - One line fix to correct the fact that our sgid/dgid pair is swapped
         from what you would expect when receiving an incoming connection
         request
