pthread, ElectricFence
Hi there! Since a cvsupdate and recompile some time ago, using ElectricFence with pthread programs got impossible. just linking the pthread lib and the efence lib to a simple small program causes a weird error: Fatal error 'Cannot create kernel pipe' at line ? in file /usr/src/lib/libc_r/uthread/uthread_init.c (errno = ?) Abort (core dumped) This was tested on diffrent machines (even the nearly newest stable) but still the same error. No idea what was changed to cause that error, but is there a way to solve my problem? (Not using efence is not a good solution as i tend to make allocation mistakes ;) ) Sperber To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-hackers in the body of the message

5.0 DP2 fixit.flp woes
The fixit.flp from the 5.0 DP2 cdrom appears to be unusable. When I attempt to use it after booting from kern.flp it comes up with errors of the form: fd0c: hard error reading fsbn 2528 of 2528-2530 (ST0 40abnrml \ ST1 4sec_not_fnd ST2 10wrong_cyl cyl 70 hd 0 sec 9) accompanied by ominous clicking noises from the floppy drive. === I have created the floppy using both fdimage on Windows NT and dd on FreeBSD. I've tried 3 different floppies. Booting into CURRENT as of January 16 2001 (old, I know) and trying: dd if=/dev/fd0.1440 of=/dev/null - No errors fdformat -v /dev/fd0.1440 - No errors cmp /dev/fd0.1440 fixit.flp - No errors fsck /dev/fd0.1440 gets cannot read BLK 2552 and similar hard error as above. Mount the floppy on /mnt and try find /mnt - hard errors as above. tar cvf test /mnt # - hard errors as above === I realise that the superblock layout has changed within the last few months, so I booted up a CURRENT as of 20 October 2002. Now fsck /dev/fd0.1440 gives: cannot get disklabel for /dev/fd0.1440, inappropiate IOCTL for device however this may be because the kernel is slightly out of sync with fsck, I don't know.

Soundcard problems on laptop
Hi freebsd-hackers list, I'm new to this list, and first of all want to thank you all for such a nice system, it's my primary OS (in combination with Mac OS X). Secondly: I have sound card problems on my laptop (Celeron 850, bla bla bla). I get a strange message when I start the system : pcm0: Intel 82801BA (ICH2) irq 10 at device 31.5 on pci0 pcm0: unable to map IO port space device_probe_and_attach: pcm0 attach returned 6 Does anybody know this error? I tracked it down in the ICH driver in the kernel sources, and the error seems to be a pci manager error. Could someone give me some pointers how to fix this error, what's going wrong in the hardware, etc? (and no, this isn't an user problem, I want to fix the driver myself if needed).

kld inetsw.pr_protocol overriding + old reuse
I'm interested in whether the following could be acomplished: there's KLD module, installing some new syscalls in the kernel, as well as installing new ``struct ipprotosw'' for some protocol or another(let's assume IPPROTO_UDP). Could we just add some code in the begging of the new protocol handler (counting, statistics , etc...) and call the old one after doing that. If possible, what should be the preparation for that last call ? Any help appreciated! To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-hackers in the body of the message

If possible, what should be the preparation for that last call ? Any help appreciated! This can't really be done, without actually hacking over top of the location that contained the code associated with the previous symbol. The reason for this is that the input path sometimes ends up making direct calls, assuming that the protocol stack is stacked the way it's expected to be stacked (e.g. direct calls to routines that are in struct ipprotosw). If you need to hack over the function, you need a lot more knowledge of assembly language; it is occasionally useful for profiling an existing system. The usual reason for wanting to do this is to make TCP/IP connections that are invisible to the OS, in order to attempt to turn FreeBSD boxes into DDOS robots, without the knowledge of their owners. 8-|. If you have a specific reason for this, you can replace the entry points with explicit entry points for your own routines, that call the real (renamed) routines, indirectly, and then replace the pointers. This will work fine on systems which legitimately belong to you, and for which you are willing to recompile the kernel, in order to make your modules work. -- Terry To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-hackers in the body of the message
Re: kld inetsw.pr_protocol overriding + old reuse
It is not very simple. However Netgraph/ng_socket.c does something similar.
net_add_domain is called from ngs_mod_event().
However, it is not possible to remove this module because the feature to
remove a domain is missing.
switch (event) {
case MOD_LOAD:
/* Register protocol domain */
net_add_domain(ngdomain);
break;
case MOD_UNLOAD:
/* Insure there are no open netgraph sockets */
if (!LIST_EMPTY(ngsocklist)) {
error = EBUSY;
break;
}
#ifdef NOTYET
if ((LIST_EMPTY(ngsocklist)) (typestruct.refs == 0)) {
/* Unregister protocol domain XXX can't do this yet.. */
if ((error = net_rm_domain(ngdomain)) != 0)
break;
} else
#endif
error = EBUSY;
break;
I would be interested in this feature too ;-)
However there is no reference counter within the protosw structure, neither
within the domain structure. It seems to be difficult to remove them.
Moreover, how can the domains, that require a routing layer, be loaded ?
rn_init is called only during the boot process in order to find the
max_keylen = MAX(dom-dom_maxrtkey).
