SYS_NMLN strange value

Hi hackers, Just a little question about utsname.h (on a 4.4-release), is it normal to see a value of 32 for SYS_NMLN instead of 256 (like other implementations such as OpenBSD 3.0) ? Which is the correct one (according to POSIX) ? -- Laurent To Unsubscribe: send mail to [EMAIL PROTECTED] w

storing routine code in kernel memory using kvm interface

Hi, Is there a way to store a function in kernel memory using KVM interface ? I have written a tty spy'er, which simply hijack discipline line entries for a tty, and as you know probably, those routines must be situated in kernel land. I know that I should use KLD for that, but i'm still curiou

error in man page kvm_nlist(3) ?

Hi, I think there's an error in man page for kvm_nlist(3): a reference to kldsym(2) which doesn't exist in the manual... pinux@arrakis ~> man kvm_nlist | grep kldsym kldsym(2) is used to locate the symbol. This is a less than perfect emu- kldsym(2), kvm(3), kvm_close(3), kvm_getarg

struct module

Hi hackers, First of all thank to all people who help me, my KLD module is almost finished. I have however a small question : why the module structure is definied in /sys/kern/kern_module.c and not in ? I'm sure this question has a stupid answer.. ;-) Bye, and thanks in advance for your answe

Getting filename from descriptor or vnode struct

Hi hackers, I'm confronted to a problem when I try to hack getdirentries(2) in a kld module : To summarize, getdirentries() filled in a buffer a series of dirent struct, and the 'd_name' field represents the filename (without the full path). I must recover the full path because I've on disk a l

Hello Ian, Thanks you for your help, now I can read my cfg file from my module in a easier way ;) A another stupid question, how can I do to stop the loading process in MOD_LOAD event handler (in my case, if the cfg file doesn't exist, it should be better to interrupt..) ? Returning EINTR does

allocating userland space to call open() on a kernel module

Hello hackers, I'm currently working on a kld syscall module which needs to read a config file at startup (MOD_LOAD). Following the advice of Eugene L. Vorokov, I tried to allocate some userland space with mmap() to store a open_args struct, fill-it with copyout() / subyte()... and call open with
