[rfc] IP_BINDMULTI and IP_RSSBUCKETID support
Hi! This patch: http://people.freebsd.org/~adrian/rss/20140701-rss-1.diff Implements a few things: * It introduces IP_BINDMULTI, which allows TCP/UDP sockets to be bound to the same matching address:port. It's intended to be what Linux SO_REUSEADDR has become except I specifically wanted it to be a different option. * .. it only allows the PCBs to be created, it doesn't actually load balance between multiple sockets like this. That requires a bunch more work to happen in the general case. But! * IP_RSSBUCKETID maps an IPv4 TCP (and later UDP, and much later IPv6) socket into a specific RSS bucket rather than in the global PCB list. That way it only receives incoming connections that has to that RSS bucket ID. If userland queries the RSS setup (sysctl net.inet.rss) and creates a worker thread per RSS bucket _AND_ pins it to the correct CPU for the RSS bucket, all the transmit and receive side will stay on the same CPU. The lock contention is almost eliminated in that case. My plan: * get this into the tree and tested/debugged; * add IPv4 UDP extensions to RSS; * teach a couple of popular threaded UDP applications (eg memcached) about this; * bask in what hopefully will be a good set of benefits; * work on IP_BINDMULTI support so multiple threads/processes can listen in the same RSS bucket and get some load balancing; * add IPv6 support; * add RSS rebalancing support; * add multi-socket, multi-NIC RSS awareness.

Network Intel X520-SR2 stopping
Hi all, I'm having problems with a 10GbE Intel X520-SR2 interface. After a running time, the interface does not send or receive more data. I am obliged to make a down and up the interface for it to return to work. Have changed the interface, optical cords, optical modules and problem continues.

Re: propose a new generic purpose rule option for ipfw
Hi,
Back from the world cup,Let's talk about the topic of U32,
You guys are right, It is almost useless if it can only filter by the 5
tuples.
But in my opinion, It can do regex match based on the pattern. So it can
do something layer7 filtering.
Sure the performance is biggest issue.
Any comments?

Sure, that is the reason why developers are providing more and more
rule options. But the my question is do we have enough options to match all
the fixed position values?
we do not have an option for fixed position matching.
Can I say that ???It will be useful when a user come up with a special
requirement which cannot be fulfilled by any existing rule option.??? Since
there are so many rule options already. So I don???t know when that special
requirement will appear. L that is what you said ???useless???, I accept
that .
please re-read what i said below. 'mostly useless' != 'useless',
and i am ok importing a clean implementation.
As i said, feel free to submit one and i will be happy to import it if
the code is clean (btw i am still waiting for fixes to the other 'rate
limiting' option you sent), but keep in mind that 'fixed position' is
mostly useless.
Which `rate limiting`, the `Packet per second`?
http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/189720
ok commented the remaining problems with a separate email.
More useful options would be one where you express the position as
'{MAC|VLAN|IP|UDP|TCP|...|PAYLOAD}+offset'
It is possible,
match position mask value
the mask can be a pattern , then that means it can match multiple
value at the same time.
what i wrote is a completely different thing. Never mind.
cheers
luigi
so at least you can adapt to variant headers, or one where you can look
for a pattern in the entire packet or in a portion of it.
cheers
