device_t, resource, and softc
Hi. Im busy implementing a kernel module to enable me to read/write certain control registers for a PCI card. I do not wish to modify the existing driver, merely create an add-on module that can be loaded to accomplish what I need. I can easily get the device_t structure of the device, and I know I can use device_get_softc, to get the softc of the structure. I also see there used to be a bus_get_resource function that no longer seems to be documented or has a man page on FreeBSD. So I was wondering if there is a way to get the resource for the device using the device_t structure, which would allow me to easily use the rman_get_bustag, and rman_get_bushandle functions to get the bus_tag and bus_handle values for the device and its resouce.

bus_space_tag, bus_space_handle
Hi. Im currently needing to write to a few registers for a PCI device. The driver is provided, but it does not contain support for writing specific registers itself. I also do not with to modify the driver. I would like to know what the best method would be for writing to these registers, the best way to go about getting bus_space_tag, and handle for the connected pci device. Im currently using FreeBSD 7.x.

Kqueue queries
Hi. I just have a few queries regarding kqueue. Ive read through the tutorial given on the netbsd page, as well as the pdf detailing kqueue. What I want to do is write a single threaded server for listening for connections, and then check if they are ready to be read from for each connection. Ive written the code for this already, and got it handling multiple connections, the problem comes in when the sockets close. This is my kevent call: nev = kevent(kq, events, number_events, changes, number_events, NULL); I wanted to know, what must be done when the sockets/file descriptors close. Do I need to decrease number_events and resort the events array so that all the active kevents are sequential without any closed sockets still in that array? Or, is it possible, to just keep increasing kevents and leave the closed socket/file descriptors in the events array, and just mark them as EV_DISABLED | EV_DELETE? When I detect a closed socket, I have tried the following, but to no evail: close(changes[i].ident); EV_SET(changes[i],changes[i].ident,EVFILT_READ,EV_DISABLE | EV_DELETE ,0,0,0); kevent(kq, changes[i], 1, NULL, 0, NULL); If I do the above, and just keep increasing number_events and just mark the kevent as EV_DISABLED or EV_DELETE then all it does is return that event as soon as I call kevent() with the following values: ident : 7, filter : -1, flags : 16384 Any suggestions/help would be appreciated, as well as pointing out if im doing something stupid here.

Keyboard Boot Disable
Hi. I have a large amount of servers, and the problem is, that when I need to plug a keyboard into them, the keyboard is disabled since they werent booted with a keyboard. I was wondering if anyone has some idea of how to disable the keyboard probe at boot and make it so that the OS thinks that the keyboard is present even if its not plugged in, so that a keyboard can be plugged in at any stage, and will function normally. Im speaking specifically for ps2 keyboards. Is this even possible, or are there architecture problems or something else relating to this that would make this impossible? If this is possible, could someone please point me in the correct direction as to which code I would need to look at to make this possible?

tty's and no login
Hey Im not sure if this is the right list, but anyway, let me know if im wrong. What im trying to do is, have a custom program run on a specific tty. Say like ttyv4, or so. But I would like to do this without having to login to this ttyv. So instead of being presented with a login option, I would like to be able to switch to ttyv4, and have it show me the output of the program that is running and using that terminal for output.

RE: tty's and no login
Yeah. That does help quite a lot. However, I did find something regarding this called own-tty, but that was for linux, and also written in like 1998. http://www.canonical.org/~kragen/sw/usershell.html I was actually hoping to do something similar. In that I was hoping to just write a single program to take control of the terminal and all me to use it for my input/output directly. Ive tried the above program, but it does complain about TIOCSCTTY: Operation not permitted. Anyone have any ideas about what exactly needs to be done to get the own-tty.c program to function correctly under FreeBSD?

Memory Leak Free Problem
Hi I have the netapp code they release for icap server. Ive ported it to FreeBSD. And I have found there is a memory leak in the code itself. Ive tried contacting netapp directly, but no reply. Their code can be found at : http://www.i-cap.org/spec/icap-server10.tar.gz Ive been trying to fix the memory leak, and I think i've found the problem, but when I try to free the buffer, I get this error. icap_srv in free(): warning: page is already free In the function : api_modify_respmod(const char* icap_hdr, const char* client_hdr, const char* origin_resp_hdr, const char* origin_resp_body, int origin_resp_body_len) We have this section of code: 1. new_body = api_filter(origin_resp_body,origin_resp_body_len); 2. origin_resp_body_len = new_body-length; 3. origin_resp_body = new_body-data; I figure that the memory leak is occuring with origin_resp_body being assigned to the new_body buffer. But if I try to insert a free(origin_resp_body) between line 1. and 2. I get the error icap_srv in free(): warning: page is already free when running the program, or either the error free(): warning: junk pointer, too high to make sense I was wondering if there is somethign missing here. Ive checked the function api_filter, and it doesnt do anything in regards to free'ing origin_resp_body, and ive also checked the data in the buffer origin_resp_body before and after the function call to api_filter, and both values are exactly the same. The entire program is threaded, and I suppose it could be possible there is some kind of thread problem occuring here? Ive also run the program through valgrind, to try and find the other memory leaks, but that one seems the most obvious when going through the code. Anyway, I would just like to know if anyone has any ideas or suggestions, or to point out that im a complete moron and missing something, anything would be welcome.

FD_ZERO problem
Hi
Ive been looking at nbtscan, the 1.5.1 version, and it seems to core, with a
segmentation fault.
I traced the problem down to a FD_ZERO(fdsr).
I was wondering is there any like checking that can be done before issuing that
command. Its part of a while loop, inside the
program, where it runs fine, till the last loop, im guessing maybe its maybe
doing an extra loop where it shouldnt, but the while
loop is
while( (select(sock+1, fdsr, fdsw, NULL, select_timeout) ) 0 ) {
So I dont think the while is giving a false positive, but this isnt my code, I
havent had time to check it all out, but I was just
wondering if there are any checks that can be done to the fd_set * fdsr pointer
before issuing a FD_ZERO?

Pci Question
Hi Im trying to write a userland program that writes to the IOPORT BAR's of a pci card. I can find the card and all that fine. But im a bit lost on exactly what address the IOPORT BAR's would be then? Im using the /dev/pci and pci(4) functions to find the card. Ive seen in the linux version of those code, that they take the base_address's and then ~0x03 them, and use that value for reading and writing with inb_l and outb_l. Ive tried using that on FreeBSD, but with outl and inl, as well as writel and readl, but I keep getting Bus error. Is there perhaps something that I am missing or forgetting, also im running the program as root. If anyone has any suggestions, they would be most welcome.

PCI Programming
Hey
Im currently trying to port some linux pci driver to FreeBSD code. But im
running into a problem. Its using a function that I cant
seem to find the equivalent of for FreeBSD.
Heres the function up to the point where im getting stuck.
int FindDevice( void )
{
static struct pci_dev *pciptr;
int pci_info_index = 0;
U16 wDev;
unsigned int tmp_addr;
/*-*/
#ifdef CONFIG_PCI // find the specified device and its configuration
if( pcibios_present() ){
pci_for_each_dev( pciptr ){
if ((pciptr-vendor == VENDOR_ID) \
(pciptr-device == DEVICE_ID) \
(pciptr-subsystem_vendor == SUBSYSTEM_VID) \
(pciptr-subsystem_device == SUBSYSTEM_DID) \
(PCI_FUNC(pciptr-devfn) == 0) )
{
DevExtension[pci_info_index].wBus= pciptr-bus-number;
DevExtension[pci_info_index].wDevFunc= pciptr-devfn;
DevExtension[pci_info_index].wCard = pci_info_index;
tmp_addr = pci_resource_start( pciptr, 4 );
DevExtension[pci_info_index].func0_bar = (tmp_addr ~0x03);
now the function im getting stuck at, is the tmp_addr =
pci_resource_start(pciptr, 4). I was wondering if anyone knows of an
equivalent under FreeBSD. Or if there is a way to obtain that value with some
other method in FreeBSD. I am pretty much fine up
until that point.
If anyone has any sample code or anything that I could read to proceed any
further, it would be greatly appreciated.

Dynamically Linked Library Problem (maybe)
Hey. I have a Freebsd server running freebsd-4.9-stable. I cvsupped the ntop src last week for 3.1.1. I then had no problems what so ever building ntop, except for the xml plugin saying it was not built, cause it cannot find xmlversion.h, even though I have libxml installed, and specified the right paths to the .h. But that is not the problem. Ntop runs and works fine on this box, not a single problem that I can see. The problem is that, I have a few other servers, that I want to copy ntop too, but dont want to build it on all those boxes. I created a tar with all the ntop binaries, as well as all the libraries that its linked too, as well as all the plugins that ntop uses from both the /usr/local/lib directory as well as the plugins from the /usr/local/lib/ntop/plugins directory. I rebuilt all the symbolic links for all the libraries and plugins and all the files that ntop was linked too. I have also checked all the permissions on all the files and they are all the same. One other thing, the boxes that I am copying ntop to, are almost exact duplicates of the first box that I built ntop on, and where it works fine. The problem is, when running ntop on the boxes that I copied it to, after checking all the permissions and links and everything, I get these errors with regards to the plugins. Tue Mar 1 05:37:16 2005 **WARNING** Unable to locate plugin '/usr/local/lib/ntop/plugins/icmpPlugin.so' entry function [Invalid shared object handle 0x29a14000] Tue Mar 1 05:37:16 2005 **WARNING** Unable to locate plugin '/usr/local/lib/ntop/plugins/snmpPlugin.so' entry function [Invalid shared object handle 0x29a16400] Tue Mar 1 05:37:16 2005 **WARNING** Unable to locate plugin '/usr/local/lib/ntop/plugins/sflowPlugin.so' entry function [Invalid shared object handle 0x29a19800] Tue Mar 1 05:37:16 2005 **WARNING** Unable to locate plugin '/usr/local/lib/ntop/plugins/rrdPlugin.so' entry function [Invalid shared object handle 0x29a1bc00] Tue Mar 1 05:37:16 2005 **WARNING** Unable to locate plugin '/usr/local/lib/ntop/plugins/pdaPlugin.so' entry function [Invalid shared object handle 0x2bcae400] Tue Mar 1 05:37:16 2005 **WARNING** Unable to locate plugin '/usr/local/lib/ntop/plugins/netflowPlugin.so' entry function [Invalid shared object handle 0x2d862800] Tue Mar 1 05:37:16 2005 **WARNING** Unable to locate plugin '/usr/local/lib/ntop/plugins/lastSeenPlugin.so' entry function [Invalid shared object handle 0x2d866c00] Tue Mar 1 05:37:16 2005 **WARNING** Unable to locate plugin '/usr/local/lib/ntop/plugins/xmldumpPlugin.so' entry function [Invalid shared object handle 0x2f697000] I have absolutely no idea how this has happened, and I have had this problem before, and not a single other person was able to help me in any regards what so ever. I was hoping maybe someone would at least know what this error even means, so that I have some idea of what I am meant to be doing to fix this.

Ntop 3.0 and Shared Library Problem
Hey Im running FreeBSD 4.9, and ive installed ntop-3.0 from Ports. Now ive had issues with this before, so i decided to remove any and all old packages, and all duplicate packages, and all dependencies that ntop has that were out of date. I then reconfigured and re-built and installed ntop from scratch. I fixed all the config errors that appeared and all options i wanted. And i built and installed ntop with both dynaic plugins enabled and --enable-static-plugin option. I have also checked that all the permissions for all the plugins and directories and everything was correct. But no matter what i do, i still get this problem.

Some of the other freebsd servers where ntop works fine, is the exact same hardware as the one above where it doesnt work. If anyone has any ideas or any suggestions, i am willing to try anything.

Pthread / Memory Problem.
Hey I have recently ported a linux application to FreeBSD, and i had to change a number of libraries and so forth. I have now managed to get it working correctly, with no build errors or warnings. The program runs correctly as well too, and there are no forseable problems. The other day i noticed it was slowly taking up more memory, very slightly, but it does. So i did post to the list a few days ago with a topic of Memory Leak. And i have now used the valgrind port for FreeBSD which someone did reply to my post with. It does say there are 2 issues that could cause memory leaks, and it looks like both originate from pthread_create. Now when porting the application i did not touch any of that code, so i am wondering, is the pthread code/library a different implementation as the FreeBSD version, cause since there are no errors, im wondering if there is just something that is missing in the code, or that has been done differently on linux that may now be causing these memory leaks. If you wish i can post the pthread_create section of code and all surrounding code, as well as the valgrind output and where its suggesting there are memory leaks.

Memory Leak
Hey I just wanted to know what programs any of you have used to track down a memory leak in your programs? Also wondering if there is maybe a good tutorial on the subject under FreeBSD or even linux if possible. Im running FreeBSD 4.9 so just looking for something try to help me track it down. Unless there is someone willing to help me with this since ive never really had to do anything like this, else i can easily read something, just kinda need to know a good memory tracing program or something of the sorts.

Pthread_create and memory issues.
Hi Ok this is just a more direct question that the thread Memory Leak. I have a program using pthread_create, and it runs fine, no compile errors or warnings, it all works fine, not a single issue, but it very very slowly uses up memory. The program creates a fixed number of threads, and after each one has run to completion it stores them for a while for use again if needed soon, else it destroys them after a specified amount of time. Now i have tried to use ElectricFence to try track down the program, and it created cores all pointing round about to pthread_create. So then i tried to use mpatrol, and it either doesnt even crash, or cause errors, or it creates a core file that is so large with so many instructions, that is well over 1000 instruction calls, but as far as i can see they both seem to be pointing to pthread_create. With mpatrol i set MPATROL_OPTIONS=LEAKTABLE, but it never produces any output and crashes before i can even test the program. It also uses up close to 100% of the cpu before crashing. I was just wondering if anyone else has had any other memory debugging program suggestions, or has had any issues with pthread_create. If you want i can post the code or at the very least my pthread_create call.

SIG_IGN
Hey Im writing a threaded program to handle connections coming from squid. And the program is working fine, except that i cant seem to set signal(SIGPIPE, SIG_IGN) It doesnt give any errors when performing that command, and then when i check to see what SIGPIPE is set to, it apparently isnt SIG_IGN. So i started to search google and i did find a page where guys had the same problem, but that was on linux and not FreeBSD. Im running FreeBSD 4.8-RELEASE gcc version 2.95.4 20020320 [FreeBSD] If anyone has any ideas please let me know.

Library problems
Hi I have recently installed ntop 3.0 on freebsd 4.9 from the ports. I then copied the binary and all needed libraries to another box also almost a duplicate of the box that i installed ntop 3.0 on. When starting up ntop i get these errors, so i recompiled ntop on the new box from ports, and i still get these errors. I have checked /usr/local/lib/ntop/plugins, and everything is there, and they are also the same as the libraries on the original box that i installed ntop on. Even copying the files from the plugin directory to the second box didnt solve this. I have recompiled, reinstalled, tried everything, i have no idea why it is now doing this.

Vlan Problem/Bug maybe
Hey I run freebsd 4.9-Stable. And i also use vlans and a program called freevrrp for redundancy. For freevrrpd to function, it needs to change the ether MAC addresses of the interfaces it is told to use. I found that if i assign it only to a vlan interfaces such as vlan0 or whatever, that it changes the ether MAC adddress of it fine. The problem then, is that no traffic is ever picked up by that interface after that. After a few dumps and stuff, i realised that it is using the new ether MAC address in the packets it sends out, which is now different from the parent NIC's ether MAC address. So somewhere along when the responses are sent back, they are not being handed back to the Vlan device. As soon as i changed the NIC's ether MAC address to match that of the new vlan ether MAC address, everything works fine again. Now this isnt really a feasible option. So i would like to know if there is anyone that could possibly help with some sort of patch to the vlan driver if_vlan.c so that when it has its ether MAC address updated, it also updates the ether MAC address of the parent device. Ive done a bit of looking and i see that somewhere in the vlan_start function inside if_vlan.c the ether MAC is being changed there, but i would also like to know how to send the new ether MAC address to the parent device driver and have it update itself. If there is a better list to send this too or if anyone could possibly help, it would be much appreciated.

Mbuf Question
Hey I have a quick question. Is it possible to find out which mbuf clusters are allocated to specific programs that are running or is that impossible.

Winbond Hardware watchdog
Hi, im busy writing a program to interface with a winbond IO chip on the motherboard, the ports that i need to write and read from are 2e, and 2f respectively, the problem is that i can read from the chip fine, that works, but it appears as if i cant write to the chip, i have tried both the /dev/io interface as well as i386_set_ioperm f I would like to know if freebsd blocks direct hardware writes, or if there is something else that i need to do in order to allow the write through. My kern secure level is 0 and im running the program as root at the moment to avoid any restrictions. If anyone has any ideas, please let me know Thanx Cole To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-hackers in the body of the message

SMP changes from 3.0 to 3.3?
At work we have 18 or so web servers runing FreeBSD 3.0 on daul PIIs. When they see very high loads (~300+) the SMP starts do get confused and things randomly fail. Were there signifigant SMP changes from 3.0-RELEASE to 3.3-RELEASE that may make SMP more stable at high loads? Are their any signifiant SMP changes at all from 3.0-RELEASE to 3.3-RELEASE? Or should I just go try and read the comit logs and see if I can make any sense of this my self? Last time I tried, I didn't get to far :( Thanks much. -- --Travis "Linux is something for Windows haters, BSD is something for Unix lovers" (Heike S., Febr. 98) To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
