Kernel space sockets

Hi, I'm trying to implement a UDP server in a kernel module. So far I have created the struct socket using sock_create_kern(), and used sock->ops->bind() on it. Now how do I send UDP datagrams? I looked at some code and found the function sock->ops->sendmsg() but I can't figure out where to put

System call problem

Hi, I am implemeting a new system call for a project I'm working on. I added the system call to the file arch/i386/kernel/process.c and added the relevant entries in the files arch/i386/entry.S and include/asm-i386/unistd.h. My system call is made up of only two lines, a printk statement, and a

EXPORT_SYMBOL question

Hi, I have 2 modules. The first one uses EXPORT_SYMBOL to make some function available to other modules. These prototypes for these functions were also put in a header file. Now the second module uses the functions the functions defined in the first module by and includes the afore mentioned he

Linux virtual memory manager

Hi, Can someone point me to a document explaining the differences between the 2.4 and the 2.6 virtual memory manager. Particularly I am looking for the function/s that replaces the try_to_swap_out() in the 2.6.x series of kernels. Thanks Josef - To unsubscribe from this list: send the line "uns
