Re: [RFC][PATCH -mm 0/5] proposal for dynamic configurable netconsole
Thank you for your comments. So, I propose the following extended features for netconsole. 1) support for multiple logging agents. 2) add interface to access each parameter of netconsole using sysfs. This patch is for linux-2.6.20-rc1-mm1 and is divided to each function. Your comments are very welcome. Rather than extending the existing kludge with module parameter, to sysfs. I would rather see a better API for this. Please build think about doing a better API with a basic set of ioctl's. Some additional What advantage do we use a set of ioctl's compared to sysfs? I think that sysfs is easier and more readable than the ioctl's to change configurations(IP address and port number and so on). ex) # cat /sys/class/misc/netconsole/port1/remote_ip 192.168.0.1 # echo 172.16.0.1 /sys/class/misc/netconsole/port1/remote_ip # cat /sys/class/misc/netconsole/port1/remote_ip 172.16.0.1 And the sysfs doesn't need to create access program such as the ioctl's. If you change configurations related to netconsole through the sysfs interface, a simple script file including a set of commands such as above echo will help you set up automatically. things: - shouldn't just be IPV4 specific, should handle IPV6 as well I would like to implement handling IPV6 on demand in the future. - shouldn't specify MAC address, it can do network discovery/arp to find that when adding addresses I think a userland application would rather find target MAC address and change it through the sysfs. -- Keiichi KII NEC Corporation OSS Promotion Center E-mail: [EMAIL PROTECTED] - To unsubscribe from this list: send the line unsubscribe netdev in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
[RFC][PATCH -mm 0/5] proposal for dynamic configurable netconsole
From: Keiichi KII [EMAIL PROTECTED] The netconsole is a very useful module for collecting kernel message under certain circumstances(e.g. disk logging fails, serial port is unavailable). But current netconsole is not flexible. For example, if you want to change ip address for logging agent, in the case of built-in netconsole, you can't change config except for changing boot parameter and rebooting your system, or in the case of module netconsole, you need to reload netconsole module. So, I propose the following extended features for netconsole. 1) support for multiple logging agents. 2) add interface to access each parameter of netconsole using sysfs. This patch is for linux-2.6.20-rc1-mm1 and is divided to each function. Your comments are very welcome.
