packets: Do not assume that IPv4, TCP, or ARP headers are 32-bit aligned.

Ethernet headers are 14 bytes long, so when the beginning of such a header
is 32-bit aligned, the following data is misaligned.  The usual trick to
fix that is to start the Ethernet header on an odd-numbered 16-bit
boundary.  That trick works OK for Open vSwitch, but there are two
problems:

   - OVS doesn't use that trick everywhere.  Maybe it should, but it's
     difficult to make sure that it does consistently because the CPUs
     most commonly used with OVS don't care about misalignment, so we
     only find problems when porting.

   - Some protocols (GRE, VXLAN) don't use that trick, so in such a case
     one can properly align the inner or outer L3/L4/L7 but not both.  (OVS
     userspace doesn't directly deal with such protocols yet, so this is
     just future-proofing.)

   - OpenFlow uses the alignment trick in a few places but not all of them.

This commit starts the adoption of what I hope will be a more robust way
to avoid misalignment problems and the resulting bus errors on RISC
architectures.  Instead of trying to ensure that 32-bit quantities are
always aligned, we always read them as if they were misaligned.  To ensure
that they are read this way, we change their types from 32-bit types to
pairs of 16-bit types.  (I don't know of any protocols that offset the
next header by an odd number of bytes, so a 16-bit alignment assumption
seems OK.)

The same would be necessary for 64-bit types in protocol headers, but we
don't yet have any protocol definitions with 64-bit types.

IPv6 protocol headers need the same treatment, but for those we rely on
structs provided by system headers, so I'll leave them for an upcoming
patch.

Both netdev_dump_queues() and netdev_linux_delete_queue() take the same
mutex in the same netdev, which deadlocks.

10 years agoofproto: Fully construct rules before putting them in the classifier.
Ben Pfaff [Mon, 26 Aug 2013 19:45:55 +0000 (12:45 -0700)]
ofproto: Fully construct rules before putting them in the classifier.

add_flow() in ofproto.c has a race: it adds a new flow to the flow table
before calling ->rule_construct().  That means that (in ofproto-dpif) the
new flow is visible to the forwarder threads before gets properly
initialized.

One solution would be to lock the flow table across the entire operation,
but this is not desirable:

   * We would need a write-lock but this would be expensive for
     implementing "learn" flow_mods that often don't really modify anything
     at all.

   * The code would need to keep the lock across a couple of different calls
     into the client, which seems undesirable if it can be avoided.

   * The code in add_flow() is difficult to understand already.

Instead, I've decided to refactor add_flow() to simplify it and make it
easier to understand.  I think this will also improve the potential for
concurrency.

This commit completes the initial refactoring and solves the race.  It makes
two key changes:

    1. It disentangles insertion of a new flow from evicting some existing
       flow to make room for it (if necessary).  Instead, if inserting a
       new flow would make the flow table overfull, it evicts a flow and
       commits that operation before it attempts the insertion.  This is
       a user-visible change in behavior, in that previously a flow table
       insertion could never cause the number of flows in the flow table
       to decrease, and now it theoretically could if the eviction succeeds
       but the insertion fails.  However, I do not think that this is a
       serious problem.

    2. It adds two new steps to the life cycle of a rule.  Previously,
       rules had "alloc", "construct", "destruct", and "dealloc" steps,
       like other ofproto objects do.  This adds "insert" and "delete"
       steps between "construct" and "destruct".  The new steps are
       intended to handle the actual insertion and deletion into the
       datapath flow table.

easier to understand.  I think this will also improve the potential for
concurrency.

This commit starts off by collapsing two different cases together into
(almost) one.  In particular, OpenFlow has two ways to modify a flow with a
"flow_mod" command.  You can use an "add" flow_mod to replace the flow, or
you can use a "modify" flow_mod to change it.  The differences in semantics
are minor, but until now Open vSwitch has treated them quite differently.
This commit merges both cases, treating them as variants of what was
previously a "modify".  The advantage is that add_flow() no longer has to
deal with two flows at a time in the "add" case (the old flow being
deleted, the new flow replacing that one).  This does not fix the race, but
it makes it easier to deal with in a later commit.

Transforming "add" into a form of "modify" requires that "modify" be able
to reset flow statistic counters.  OpenFlow 1.2 and later make this an
optional flag in a "flow_mod".  Until now, we haven't implemented that
feature of OF1.2+, but we get it pretty much for free with this
refactoring, so this commit also adds that OF1.2+ feature too.

ofp-util: Abstract flow_mod OFPFF_* flags.

The OFPFF_* flags used in flow_mods are just confusing enough that it
seems worthwhile to try to abstract them out.  In particular:

    * OFPFF_EMERG was introduced in OF1.0, deleted in OF1.1, and then
      its bit was reused for a different purpose in OF1.2.

    * OFPFF_RESET_COUNTS was introduced in OF1.2 but the semantics that it
      specifies are implied by "add" commands in earlier versions, so
      proper translation requires the OpenFlow version number and flow_mod
      command.

This commit does the abstraction.

a flow that has no idle or hard timeout into one that has either one or
