[osol-code] recursive rw_enter!!

I am facing problems with gld_recv() inside a pseudo network driver. It causing the kernel to panic with recursive rw_enter error. Is there a restriction on how we could call gld_recv()? Because I suspect that problem is because I am calling it in ioctl context!! Thanks, Neelam This

Re: [osol-code] Writing a pseudo network driver

Thanks a lot. It works now. Actually I just blindly followed the Linux convention. -Neelam This message posted from opensolaris.org ___ opensolaris-code mailing list opensolaris-code@opensolaris.org http://mail.opensolaris.org/mailman/listinfo

[osol-code] problems in sending packets to the driver I wrote

[osol-code] How to get the dev_info_t structure, given the name of the networkinterface

Hi, Is there a magic function in the kernel to get the dev_info_t structure, given the name of the network interface? I came across get_dev_by_name(). But not quite sure if this is the correct function, plus it's returns a void*!! Thanks, Neelam This message posted from opensolari

Re: [osol-code] Writing a pseudo network driver

Thanks Garrett. The problem was somewhere else this time. A valid streamtab struct solved the issue. Thanks a lot for all your help and time. -Neelam This message posted from opensolaris.org ___ opensolaris-code mailing list opensolaris-code

Re: [osol-code] Writing a pseudo network driver

I incorporated the structures. But whenever I try to add the driver, it crashes the kernel and reboots the machine!! This message posted from opensolaris.org ___ opensolaris-code mailing list opensolaris-code@opensolaris.org http://mail.opensolaris.o

Re: [osol-code] Writing a pseudo network driver

I think I am doing, what you mentioned in your previous post. Yes I did install the driver with add_drv which created an entry in the /devices/pseudo. Here is the code snippet. Any help will be greatly appreciated. What you might be most interested is the xnet_attach() function. /* cb_ops struc

Re: [osol-code] Writing a pseudo network driver

Thanks for the info. So, now when I called the command "ifconfig xnet0 plumb" it gave me an error "ifconfig: cannot open link "xnet0": DLPI link does not exist ". I had assumed that the gld_register() function should have created a DLPI link. Do I need to do something else to create this link. T

Re: [osol-code] Writing a pseudo network driver

Actually I want the interface to show up as an instance when I type ifconfig. I want it so that kernel can forward packets to that interface when application invoked a send() system call for instance. So I am already using a .conf file having name for the instance. I am able to create an instanc

[osol-code] Writing a pseudo network driver

Hi, I am trying to write a pseudo network driver which basically creates a network interface and acts as a layer between the actual network driver and kernel. Any pointers on creating a pseudo network interface which is not bound to any physical network interface? Thanks, Neelam This
