      netfilter: remove unused "config IP_NF_QUEUE" · 3dd6664f
      Paul Bolle authored
      Kconfig symbol IP_NF_QUEUE is unused since commit
      d16cf20e ("netfilter: remove ip_queue
      support"). Let's remove it too.

      PCI: Use ROM images from firmware only if no other ROM source available · 547b5246
      Matthew Garrett authored
      Mantas Mikulėnas reported that his graphics hardware failed to
      initialise after commit f9a37be0 ("x86: Use PCI setup data").
      
      The aim of this commit was to ensure that ROM images were available on
      some Apple systems that don't expose the GPU ROM via any other source.
      In this case, UEFI appears to have provided a broken ROM image that we
      were using even though there was a perfectly valid ROM available via
      other sources.  The simplest way to handle this seems to be to just
      re-order pci_map_rom() and leave any firmare-supplied ROM to last.

      packet: packet fanout rollover during socket overload · 77f65ebd
      Willem de Bruijn authored
      Changes:
        v3->v2: rebase (no other changes)
                passes selftest
        v2->v1: read f->num_members only once
                fix bug: test rollover mode + flag
      
      Minimize packet drop in a fanout group. If one socket is full,
      roll over packets to another from the group. Maintain flow
      affinity during normal load using an rxhash fanout policy, while
      dispersing unexpected traffic storms that hit a single cpu, such
      as spoofed-source DoS flows. Rollover breaks affinity for flows
      arriving at saturated sockets during those conditions.
      
      The patch adds a fanout policy ROLLOVER that rotates between sockets,
      filling each socket before moving to the next. It also adds a fanout
      flag ROLLOVER. If passed along with any other fanout policy, the
      primary policy is applied until the chosen socket is full. Then,
      rollover selects another socket, to delay packet drop until the
      entire system is saturated.
      
      Probing sockets is not free. Selecting the last used socket, as
      rollover does, is a greedy approach that maximizes chance of
      success, at the cost of extreme load imbalance. In practice, with
      sufficiently long queues to absorb bursts, sockets are drained in
      parallel and load balance looks uniform in `top`.
      
      To avoid contention, scales counters with number of sockets and
      accesses them lockfree. Values are bounds checked to ensure
      correctness.
      
      Tested using an application with 9 threads pinned to CPUs, one socket
      per thread and sufficient busywork per packet operation to limits each
      thread to handling 32 Kpps. When sent 500 Kpps single UDP stream
      packets, a FANOUT_CPU setup processes 32 Kpps in total without this
      patch, 270 Kpps with the patch. Tested with read() and with a packet
      ring (V1).
      
      Also, passes psock_fanout.c unit test added to selftests.

      sparc: remove unused "config BITS" · f58b20bd
      Paul Bolle authored
      sparc's asm/module.h got removed in commit
      786d35d4 ("Make most arch asm/module.h
      files use asm-generic/module.h"). That removed the only two uses of this
      Kconfig symbol. So we can remove its entry too.
