How to correctly bench IPSec performance ?

deciding where to send a packet once it has passed the filter.
Basically, passing things through the kernel stack is simple

You have to specify a single ring index as the argument

Write a second handler that takes packets from an output queue and pushes
them to a port.

Hello everyone, I've tried to build netmap on CURRENT, and to my surprise,
I couldn't load the module.
Thanks to Sean, I managed to find the cause. One file from the netmap code

Hi, Jim
thanks for reply
this is my graduate design project
my aim is to implement a simple software switch based on openflow using
FreeBSD netmap as network I/O framework
besides, I'm succeed doing on bridge.c at 2 interfaces
add like
/* Func: int main
which match the
rules(flow table), forward only matched packets to em2 em3 (forward
itself using netmap)
( I use like this:
./vale-ctl -a vale0:em0
./vale-ctl -a vale0:em1
./vale-ctl -a vale0:em2
./vale-ctl -a vale0:em3
then host1 send packets )
the point is, I don't know when/where to process
Hi,
I think it's right place to talk about FreeBSD 10 - netmap question
(location at FreeBSD 10: /usr/src/tools/tools/netmap ; with kernel device
netmap on)
I'm (entry) study on openflow software switch based on netmap/vale
It seems very simple in vale-ctl.c and hard to add features for packet
Jaye,
I’d really like to see this work happen.
Let me know if I can help.

Good catch!
Would you mind filing a bug so we don't forget?

The proposed fix, while it might fix the immediate issue, might still
not fix pointer aliasing. Perhaps there needs to be some struct or
union
Hi,
I wrote a very simple netmap program on FreeBSD 10, run one or more times,
kernel crashed. Kernel configuration is GENERIC, only added netmap. The
host is VM, running in vmplayer, one nic.
How to repeat:
1. log into the system via ssh
2. run one or more times the program in the terminal
Hi,
I have tested netmap on freescale PowerPC board, it is a big endian
machine, when I test the example app pkt-gen， I found one bug, really it is
bug of netmap souce code.
The commit id is “d39c4411a2129926d262f9faffacaf876392c7cd”, the
bug locates in “netmap_mem2.c

Hi Luigi,
I've started to play with netmap, like it a lot, and would like it to grow
support for some additional features that I'd need. I wonder if you could
comment on how likely support for any of the following

Hi
I am trying to compare the performance of sending packets using netmap,
socket and packet mmap.
Right now I am working on top of pkt-gen and some other implementations for
socket and packet mmap. I'm interested on the relation between packet size
and packets I can send per second.

Hi,
I am learning to use netmap. Currently I got pkt-gen working (without
drivers). When I try to set packet size above 2048 I got an error.
Searching through the code I found in sys/dev/netmap/netmap_mem2.c the size
constrain. I change it like this:
diff --git a/sys/dev/netmap/netmap_mem2.c b
I was able to work this around. The problem was in the driver.
Now I start working on customizing the driver to use netmap optimized

Hi

My first issue came when doing what you suggested, and try the emulated
netmap mode. I need to cross compile the code from my x86, which I think I
did correctly by setting up my arm toolchain and passing the kernel
Hi Dear Luigi,
I use your netmap pkt-gen for testing my applications and thanks you for
your great nice work.
I want to modify (if I can!) your pkt-gen such that I can insert timestamps
in udp packets in order to find delay of receiving packets (that forward
from my DUT).

() can translate
buffer indexes for any netmap buffer, even those not in a ring.
All it does is grab the base address of the buffer pool from the
ring, and add the buffer index times the buffer size.
So you can navigate the pool of extra buffers as follows
uint32_t x = nifp-ni_bufs_head
Hi Luigi,
I'm allocating extra rings and/or extra buffers via the nr_arg1/nr_arg3
parameters for NIOCREGIF.
Once I've done that, how do I actually access those rings and buffers?
For extra rings, the documentation and example code don't really say anything.
For extra buffers, the
for a VALE port has also
space to host some pipes. Otherwise, for physical ports (which at
the moment all share the same address space) there is not a real
need to specify it.
For the extra buffers, remember that NETMAP_BUF() can translate
buffer indexes for any netmap buffer, even those not in a ring.
