Ben Pfaff [Wed, 7 Jan 2015 21:19:41 +0000 (13:19 -0800)]
netlink: Refine calculation of maximum-length attributes.

Until now the Netlink code has considered an attribute to exceed the
maximum length if the *padded* size of the attribute exceeds 65535 bytes.
For example, an attribute with a 65529-byte payload, together with 4-byte
header and 3 bytes of padding, takes up 65536 bytes and therefore the
existing code rejected it.

However, the restriction on Netlink attribute sizes is to ensure that the
length fits in the 16-bit nla_len field.  This field includes the 4-byte
header but not the padding, so a 65529-byte payload is acceptable because,
with the header but not the padding, it comes to only 65533 bytes.

Thus, this commit relaxes the restriction on Netlink attribute sizes by
omitting padding from size checks.  It also changes one piece of code that
inlined a size check to use the central function nl_attr_oversized().

This change should fix an assertion failure when OVS userspace passes a
maximum-size (65529+ byte) packet back to the kernel.

users such as from nfsd via commit 6282cd565553 ("NFSD: Don't hand out
delegations for 30 seconds after recalling them.") where it has been used
as a hash function for bloom filtering.

While we think that these users are actually not much of concern, it has
been requested to remove the arch_fast_hash() library bits that arose
from [1] entirely as per recent discussion [2]. The main argument is that
using it as a hash may introduce bias due to its linearity (see avalanche
criterion) and thus makes it less clear (though we tried to document that)
when this security/performance trade-off is actually acceptable for a
general purpose library function.

Lets therefore avoid any further confusion on this matter and remove it to
prevent any future accidental misuse of it. For the time being, this is
going to make hashing of flow keys a bit more expensive in the ovs case,
but future work could reevaluate a different hashing discipline.

Jarno Rajahalme [Tue, 6 Jan 2015 19:10:42 +0000 (11:10 -0800)]
miniflow: Use 64-bit data.

So far the compressed flow data in struct miniflow has been in 32-bit
words with a 63-bit map, allowing for a maximum size of struct flow of
252 bytes.  With the forthcoming Geneve options this is not sufficient
any more.

This patch solves the problem by changing the miniflow data to 64-bit
words, doubling the flow max size to 504 bytes.  Since the word size
is doubled, there is some loss in compression efficiency.  To counter
this some of the flow fields have been reordered to keep related
fields together (e.g., the source and destination IP addresses share
the same 64-bit word).

This change should speed up flow data processing on 64-bit CPUs, which
may help counterbalance the impact of making the struct flow bigger in
the future.

Classifier lookup stage boundaries are also changed to 64-bit
alignment, as the current algorithm depends on each miniflow word to
not be split between ranges.  This has resulted in new padding (part
of the 'mpls_lse' field).

The 'dp_hash' field is also moved to packet metadata to eliminate
otherwise needed padding there.  This allows the L4 to fit into one
64-bit word, and also makes matches on 'dp_hash' more efficient as
misses can be found already on stage 1.
