Make dumping large numbers of flows possible.

This changes the kernel switch implementation to use the kernel Netlink
"dump" interface to allow flow stats that don't fit in the socket buffer
to be dumped gradually as the caller drains the socket buffer.

One of the changes here is a bug fix for nla_unreserve.  Because Netlink
attributes' lengths are rounded up to a multiple of 4 bytes, reducing
the length of the payload by N bytes doesn't necessarily reduce the
length of the skb by N bytes.  Instead, we need to know the original
length and final length of the attribute.  This means that using 'len'
as a difference in bytes doesn't really make sense, so this changes
'len' to be the new length of the attribute payload and renames the
function to nla_shrink to (IMO) better reflect what it is now doing.

Since we have to release the RCU read lock between calls to the dump
function, we need table iterators that persist across RCU epochs.  One
way to do this would be to add new "iterator_save" and "iterator_restore"
functions, but this seemed like overkill since there would then be a
total of 5 iterator functions that have only one user (flow stats dumping).
Instead, this patch refactors table iteration into a single "iterate"
function that takes a callback.  This simplifies the table iteration code
significantly.

This change also modifies dpctl to understand the new format of flow
stats.

Tolerate ENOBUFS from kernel netlink code in second call to recvmsg.

The Linux kernel returns ENOBUFS to userspace code to indicate that
a netlink message that the kernel wanted to send could not be due to
a lack of buffer space.  We checked for this and dealt with it in
one recvmsg call but not in another.  This change tolerates it in
both places.

16 years agoSupport NETLINK_ADD_MEMBERSHIP even when compiled with old kernel headers.
Ben Pfaff [Wed, 23 Apr 2008 21:25:27 +0000 (14:25 -0700)]
Support NETLINK_ADD_MEMBERSHIP even when compiled with old kernel headers.

Commit 0a9024a2d7, "Changes based on feedback from GigaFin," added support
for compiling on a system that lacked up-to-date Linux kernel headers, by
dropping support for a feature only in newer kernels on such a system.
But the code already supported such a system properly; only the lack of
a macro definition kept it from compiling.  So define the macro ourselves
instead of disabling the feature.

To elaborate, there are two issues here.

The first is kernel support for NETLINK_ADD_MEMBERSHIP.  Older
kernels don't support this.  But NETLINK_ADD_MEMBERSHIP was added
at the same time as support for more than 32 netlink multicast
groups.  Netlink multicast groups numbered less than 32 can be
subscribed using a different mechanism, and in fact we do that
for such groups.  Thus, attempting to use NETLINK_ADD_MEMBERSHIP
on an older kernel basically can't happen, and if it did it would
be a bug in the OpenFlow kernel module for telling userspace to
subscribe to a multicast group that cannot exist on that kernel.

The second is the kernel headers that the userspace programs are
compiled with.  Without the change quoted below, the userspace
programs will silently fail if they are compiled with 2.4.x
headers and then run on a 2.6.x kernel and given a multicast
group numbered above 32, because they will not even try to
subscribe to that group.  With the change, the userspace programs
will work properly when run on 2.4.x or 2.6.x kernels regardless
of the multicast group number and regardless of whether the
headers they were compiled against were from 2.4.x or 2.6.x.
