Hi all,
I am trying to check that a process (struct proc) has root powers when
it calls my KLD system call.
I know from kern_jail.c that I can use suser() but this function takes
a struct thread* instead of struct proc* although the credentials
(struct ucred *p_ucred;) are stored in proc !
Is ther
Hi all,
I have two questions concerning FreeBSD Memory management :
1 - Right now to access the memory address space of a user process
from kernel mode, I only have to set, on x86 systems, the register CR3
to the right value. How can I do that on other architectures ? is
there an architecture-ind
Hi all,
I am trying to figure out from the kernel source code (FreeBSD 5.3)
how can I perform a routing lookup in a KLD module.
Since I am short in time, if anyone knows how do to do this I would
appreciate. Any pointers to the right portion of the code are also
apperciated.
Thanks,

Hi all,
It's probably not the right mailing list to ask but I am really
surprised about global variable sharing in a multithreaded C
application. If I remember well my multithreading course global
variables are shared between threads, right ?
Example :
int counter = 0

Hi all,
I am trying to implement a small kld pseudo-device driver on FreeBSD 5.3 that
behaves just like a socket with regards to the select system call.
Currently, I am using the sample echo pseudo-device driver from
http://www.freebsd.org/doc/en_US.ISO8859-1/books/arch-handbook/driverbasics-char
Hi all,
I am experiencing a weird problem while mounting nfs files.
Configuration :

Firewalling:
absolutely everything is authorized from 192.168.0.2 on 192.168.0.1

Hi hackers,
I am wondering if I can use c++ iostreams inside the kernel ?
After all the code : cout << "Hello world!" << endl;
ends accessing the stdout just like : printf("Hello world!\n"); right ?
So if I could compile my KLD module with static linkage to libstdc++,
that should be ok, right ?
Hi hackers,
I am trying to port a software from Linux to FreeBSD (5.3). But, I

Here are the prototypes of the functions I am using:

int set_bit(int offset, int * flag);

Hi all,
I am running freebsd 5.3 under qemu (a fast IA32 emulator). My host
system is linux. Everything works fine, but I want to get rid of this
small non-scrollable window, not practical when gcc says I made many
many errors :-)...
Instead I want to get a console. In qemu's documentation it say

Hi all,
I would like to send a signal (e.g SIGUSR1) to a user process from
inside the kernel (kld module).
Can any one tell me how to do it ?
I tried the following code inspired from sys/kern/kern_sig.c :

Hi all,
I am wondering if any one knows about a generic parser which takes a
packet (mbuf) of a certain protocol (e.g RSVP ) as input and generates
some data structre representing the packet ?
I've been searching for a while and found that ethereal and tcpdump
for example use specific data struct
hanks in advance.
