About bricks-shell runtime error

[shuaidonga]

After I installed it according to the reademe documentation.
Execute in the shell. /bricks -d /usr/local/etc/bricks-scripts/utils.lua /usr/local/etc/bricks-scripts/configs/single-threaded-setups.lua
Then execute the bricks-shell
The following error occurred
。

@shuaidonga,

Since you are using a remote lua shell to connect to the bricks daemon, I suggest that you type in your code as a block, e.g. lb = Brick.new("LoadBalancer", 2); lb:connect_input("eth5") in the shell. You should probably run the binary like: bricks -d -f /usr/local/etc/bricks-scripts/startup-one-thread.lua

As a start, I suggest that you try running packet-bricks as a foreground process (bricks-server [-f startup_script_file]). Your commands should eventually be written in the form of a lua function and then stored in a script (similar to functions as defined in startup-one-thread.lua.

@ajamshed ,
i am try running packet-bricks as a foreground process.Some errors occurred during runtime.

Are you running as root (or with sudo)?
Can you please check if example netmap applications are running fine (such as pkt-gen?

[shuaidonga]

@ajamshed
I have run as root.
Netmap application running is fine.

@shuaidonga ,

Hmm.. interesting. I tested packet-bricks (FreeBSD version) just two weeks ago. I believe you are running the Linux version (based on your output log). Can you please share the following details with me:

1- Linux kernel version,
2- Netmap commit ID,
3- Network adapter specs, and
4- your lua startup script.

I will test out packet-bricks in my testbed once you have provided me the details. nm_open() is failing which means that some part of the netmap Linux API has changed since the last time I updated the code.

@ajamshed
More details are as following
1、Linux kernel version is 3.10.0-327.el7.x86_64
2、Netmap commit id is fbeeaeea43be8858be0895f19170377f06e77dd3
3、NIC information is Broadcom Corporation NetXtreme II BCM57810 10 Gigabit. NIC driver is bnx2x
4、bricks -f /usr/local/etc/bricks-scripts/startup-one-thread.lua

@shuaidonga ,

Does netmap support bnx2x NICs? Please read this:
https://github.com/luigirizzo/netmap/tree/master/LINUX#nic-drivers. And then this: luigirizzo/netmap#13.

Can you please verify whether you were emulating netmap with pkt-gen? Most likely packet-bricks fails at nm_open() because it is trying to create netmap pipes.

By the way, there is no netmap patch for bnx2x driver over here as well: https://github.com/luigirizzo/netmap/tree/master/LINUX/final-patches. Do you have an Intel NIC that you can try running packet-bricks with?
