Re: sosend() and mbuf
OpenKETA has its own kthread_create() with a little modification from kthread_create(), it associates the new thread with curthread not with the thread0. See /usr/sys/kern/kern_kthread.c: kthread_create() error = fork1(&thread0, RFMEM | RFFDG | RFPROC | RFSTOPPED | flags, pages, &p2); OpenKETA:kthread_create() error = fork1(curthread, RFFDG | RFPROC | RFSTOPPED | flags, pages, &p2); I'll give it a try and see if it works. BUT i still can't understand why kern_open() don't work, except in the original thread.

Re: sosend() and mbuf
No my code doesn't work, I thought it may be because that soaccept()
-which is not found in man 9- is non-blocking, so i've to put my code
in a thread.
Now i got another problem, when I open a text file from this thread,
the kernel crashes, I'm sure that its the thread.
kthread_create((void *)thread_main, NULL, NULL, RFNOWAIT, 0, "thread");
void thread_main(){
struct thread *td = curthread;
int ret;
int fd;
ret = f_open("/path/to/file.txt", &fd);
printf("%d\n", ret);
tsleep(td, PDROP, "test tsleep", 10*hz);
f_close(fd);
kthread_exit(0);
}
int f_open(char *filename, int *fd){
struct thread *td = curthread;
int ret = kern_open(td, filename, UIO_SYSSPACE, O_RDONLY, FREAD);
if(!ret){
*fd = td->td_retval[0];
return 1;
}
return 0;
}
I've to finish up this problem to go back for the first one.
Can you figure out what's wrong with this code, it works when I call
thread_main() rather than kthread_create((void *)thread_main, .
Thanks a lot

sosend() and mbuf
Hello Guys,
I can't find useful information on sosend(), I would like to send some
plain text through sosend()
Here is what i got so far, I don't know how to use mbuf with sosend()
to achieve this.
ret = socreate(PF_INET, &s, SOCK_STREAM, IPPROTO_TCP,
curthread->td_ucred, curthread);
printf("socreate -> %d\n", ret);
bzero(&sa, sizeof(sa));
sa.sin_len = sizeof(sa);
sa.sin_family = AF_INET;
sa.sin_port = htons();
sa.sin_addr.s_addr = INADDR_ANY;
sobind(s, (struct sockaddr *)&sa, curthread);
printf("sobind -> %d\n", ret);
ret = solisten(s, 4, curthread);
printf("solisten -> %d\n", ret);
ret = soaccept(s, (struct sockaddr**)&psa);
printf("soaccept -> %d\n", ret);
tsleep(curthread, PDROP, "kHTTP tsleep", 10*hz);
/* iovec */
aiov.iov_base = buf;
aiov.iov_len = strlen(buf);
/* auio */
auio.uio_iov = &aiov;
auio.uio_iovcnt = 1;
auio.uio_offset = 0;
auio.uio_resid = strlen(buf);
auio.uio_rw = UIO_WRITE;
auio.uio_segflg = UIO_SYSSPACE;
auio.uio_td = curthread;
> ret = sosend(s, (struct sockaddr*)&sa, &auio, 0, 0, 0,
curthread);
printf("sosend -> %d\n", ret);
ret = soclose(s);
printf("soclose -> %d\n", ret);

Controlling a process
Hi guys, What is the best way to control a process (running in chroot env): 1- Execution time 2- Memory limit And to be able to kill the process when it breaks this limits. Finally, i would like to know the exit status of the process or the signal that killed it (sigfault, .) The idea is that I'm developing a problem judge that runs FreeBSD (something like www.spoj.pl or topcoder.com/tc) Where every problem has a run-time and a memory limit.

Re: pgk_add segmentation fault
Hi, It seems that pkg_add tries to executes ldconfig which itself cause the segmentation fault.

Re: ``Stopping RAM access''

I think this has no aim, RAM tests should be done during booting, but u could try to disable interrupts while in kernel mode 'cli' which will prevent any further context switching, then try to do whatever you want, finally enable interrupts back 'sti'. That's my two cents.

Re: loading a firmware image
The firmware is bundled in a seperate kernel module that can be loaded,
read and then unloaded. See src/sys/modules/iwifw/iwi_bss for an example
of the Makefile magic that creates the kld.
if i wrote FIRMWS = filename:shortname:version in the Makefile
then i should user firmware_get("shortname") rather than
firmware_register(), is it right ??

Re: ARP Spoofing
You can use static arp entries on all the involved hosts/routers, to hardwire a MAC-address to an IP-address. This can be done with 'arp -s ' on FreeBSD. Such static arp entries will not be overridden by incoming arp replies and will ensure that outgoing IP packets are sent to the right mac address.

Re: Sysinstall sucks
Strange enough, since sysinstall writes to disk ONLY after you set all options and press YES. BTW at (1) you write that sysinstall had finished before your MBR was wiped out. So did sysinstall finish, or it catch the some signal? Stas It didn't run at all fdisk, it catch a some signal and crash. I didn't need to repartation since i've already 2 bsd slices each has each own partitions so i just clicked on the labeling step and make some changes to the partitions inside the already bsd slice (ad0s4). Then everything contiued normally, and the system has been installed. but i found grub (installed on MBR with files on linux ext3 partition) gives as i remember error 22, i booted my slack cd and run cfdisk and found that parititions is no longer available and marked as empty space. I used gpart and fixed the problem, and i didn't need to re-install anything. even the newly installed freebsd system was preserved. -- I'm Searching For Perfection, So Even If U Need Portability U've To Use Assembly ;-) http://www.maslanlab.org http://libosdk.berlios.de ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"

files refused to delete
when i've extract a bz2 file containing filenames in other encodings (arabic), the file names appears ??? and it refuses to delete , however i deleted them from linux but the fsck created a hard link to them in lost+found and this hard links refused to deleted, it also created a hard link to my home directory which also refused to delete. is this bug in bfs or in fsck ??? -- I'm Searching For Perfection, So Even If U Need Portability U've To Use Assembly ;-) http://www.maslanlab.org ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
