      inet: remove old fragmentation hash initializing · 7088ad74
      Hannes Frederic Sowa authored
      All fragmentation hash secrets now get initialized by their
      corresponding hash function with net_get_random_once. Thus we can
      eliminate the initial seeding.
      
      Also provide a comment that hash secret seeding happens at the first
      call to the corresponding hashing function.

      ipv6: split inet6_hash_frag for netfilter and initialize secrets with net_get_random_once · b1190570
      Hannes Frederic Sowa authored
      Defer the fragmentation hash secret initialization for IPv6 like the
      previous patch did for IPv4.
      
      Because the netfilter logic reuses the hash secret we have to split it
      first. Thus introduce a new nf_hash_frag function which takes care to
      seed the hash secret.

      ipv4: initialize ip4_frags hash secret as late as possible · e7b519ba
      Hannes Frederic Sowa authored
      Defer the generation of the first hash secret for the ipv4 fragmentation
      cache as late as possible.
      
      ip4_frags.rnd gets initial seeded by inet_frags_init and regulary
      reseeded by inet_frag_secret_rebuild. Either we call ipqhashfn directly
      from ip_fragment.c in which case we initialize the secret directly.
      
      If we first get called by inet_frag_secret_rebuild we install a new secret
      by a manual call to get_random_bytes. This secret will be overwritten
      as soon as the first call to ipqhashfn happens. This is safe because we
      won't race while publishing the new secrets with anyone else.

      ethernet: remove unnecessary pci_set_drvdata() part 4
      
      Since commit 0998d063
      (device-core: Ensure drvdata = NULL when no driver is bound),
      the driver core clears the driver data to NULL after device_release
      or on probe failure. Thus, it is not needed to manually clear the
      device driver data to NULL.

      net: always inline net_secret_init · 34d92d53
      Hannes Frederic Sowa authored
      Currently net_secret_init does not get inlined, so we always have a call
      to net_secret_init even in the fast path.
      
      Let's specify net_secret_init as __always_inline so we have the nop in
      the fast-path without the call to net_secret_init and the unlikely path
      at the epilogue of the function.
      
      jump_labels handle the inlining correctly.

      did modify the memory_pressure-field of struct cg_proto, but not the one
      of struct proto.
      
      So, the access to sk_prot->memory_pressure should not be changed.
