adding an address family
Hi, I wonder if it is possible to dynamicly add an address family from a kernel module. I ask this because I am working on IrDA support for FreeBSD. I want to create AF_IRDA and all the corresponding structures and functions. So would it be possible to add another network stack at runtime or is the code not ready for that?

Re: Setting default hostname to localhost
A look at /usr/src/libexec/getty/main.c shows the folowing: if (hostname[0] == '\0') strcpy(hostname, "Amnesiac"); so, coherence suggests that the default should be "Amnesiac". Othewise, you'll get different hostnames for dhcp (and the like), and getty sessions. regards, mouss At 11:45 12/01/01 -0800, Archie Cobbs wrote: There is an RFC that specifies a "private use" top level domain, analogous to 192.168.0.0/16, 10.0.0.0/8, etc. The domain is ".local" so any default ending in ".local" should not conflict. -Archie ___ Archie Cobbs * Whistle Communications, Inc. * http://www.whistle.com To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message

Also, you're computing strlen too many times, and strlen is a loop
(while (*ptr) ptr++). so I suggest using a pointer to the string as in
/usr/bin/dirname/dirname.c. mainly:
if (*path == '\0') return "/"; /* if const is not ok, strdup("/") */
ptr = path;
while (*ptr) ptr++;
while ((*ptr == '/') (ptr path)) ptr--;

you already did that (I mean trimming the trailing slashes).
Finally, I'd propose adding such a function (dirname) in a library (either libc
or say libfile) to allow code reuse. such a lib would contain functions
such as basename, dir_create (mkdir -p), so that the commands
mkdir, rmdir, cp, mv, ... etc call the lib functions instead of rewriting code.

As somebody already pointed out, there *is* a dirname(3) function, and even
a dirname(1) cmdline utility to invoke it.
In a followup to Alfred's mkdir(1) commit, I sent a sample implementation
of a direxname() function, which calls dirname(3) in a loop, and returns
the longest existing path component. I'll get back to him shortly
with a patch to mkdir(1) using direxname() to report a meaningful error
message, something like "Cannot create /exists/nonex/foo/bar, nonexistent
path components after /exists". In the meantime, attached is my first
shot at direxname() implementation, using dirname(3)'s static buffer.
G'luck,
Peter

I'm not convinced you really need to check which is the "largest" parent that exists. if /a doesn't exist, and I do a mkdir /a/b/c/d, just a "/a/b/c does not exist" is far sufficient. For me, if you ignore permissions and the like, the condition to create a directory is that its parent exists, whatever are his grand-parents. after the error is shown, one will anyway check which dirs exist. doing the stat() on all those just consumes time, with few benefits. on an NFS mounted fs, this would be just annoyiing sometimes. now if you really insist, I'd suggest doing the stat the other way: check the root, then its children, then the children of the latter... like in mkdir -p. at last, note that there might be race conditions while you stat(). but there is hardly a way to avoid'em. at least, a single stat() reduces the window of opportunity. regards, mouss To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
Re: FreeBSD boot manager, where is latest version?
I've recently switched to Smart Boot Manager which I noticed on freshmeat awhile ago.

For fitting in the boot block (no seperate partition required) it has quite a number of features.

Apparently, in three versions of FreeBSD, this is _still_ a problem. Does anyone have any insight on this? I have a wee bit more insight on this. The gotcha seems to involve getty vs ttyd0 and cuaa0. I want to accomplish at least these things (a bit more fleshed out): - boot messages to the serial port (hence, a serial console) - a login prompt (hence, I need getty running) - syslog logging to /dev/console (as opposed to root's tty) - the general ability to write to the console directly (ie: /bin/echo 'test to console' /dev/console) - due to serial cabling issues out of my control, it appears that I need getty attached to cuaa0, rather than ttyd0. (The test box below doesn't have this restriction, but I'm trying to spec several boxes in the data center, and there seem to be some variability in the cables that are resolved in using cuaa0.) I have a 3-4.RELEASE box, with a serial console. mdb1# dmesg | grep sio0 sio0 at 0x3f8-0x3ff irq 4 flags 0x10 on isa sio0: type 16550A, console My observations so far: - If getty is not running at all on the serial device, then both syslogd and direct writes to /dev/console just work. - If getty is running on cuaa0, writes to the console by either syslogd or a direct write block. 'ps' shows the process's state as 'I', and it's flags are '86', neither of which reveals much info. :/ (Advice is welcome about getting more info without 'ktrace'...) - If getty is running on ttyd0, then the direct writes work, but syslog doesn't. So - it would seem that out-of-the-box, FreeBSD can't be used adequately in a headless environment, as much as it pains me to state as much. In researching the mailing list archives (well, several lists, but you know what I mean), it would seem people have been running into problems associated with these issues for a couple of years now, over a few versions of FreeBSD. - Is anyone actually able to use FreeBSD in a headless environment with impunity, as per my needs above? If so, specs of hardware/software would be most welcome. - Any advice on kernel/device driver tweaking to resolve the blocking issues would also be appreciated... - What would the ramifications be of running getty on /dev/console?

NFS_ROOT not working when using a Netapp server

This opens the opportunity to use a cron daemon from ports as
well as settling another - maybe repo copied - cron variant in
the FreeBSD tree (although I fail to estimate how probable this
is to happen). For highly involved developers this opens the
opportunity to plug in an own cron version or to pass options to
locally modified sources.
But I recognize that there are strong concerns about touching the
current src/usr.sbin/cron tree -- it is expected to be broken by
being touched. For whatever the definition of "broken" might be:
deviation from expected behaviour or introduction of real bugs.

I've now written the driver for the chipset on my laptop, and I am ready with that to pass data to an upper layer. In Linux IrDA is handled as AF_IRDA, so in userland you create an AF_IRDA socket just as you would do with a normal TCP/IP stack and then you can commnunicate with other IrDA devices. I had two questions: 1. How can I dynamicly implement a new network protocol as a kernel module. The answer for that one seems to be Netgraph Following to that one I had another question: 2. Is Netgraph going to be the future in FreeBSD network stacks. Iaw, will tcp/ip be based on Netgraph in the future or will it just be a nice extension but not more. The reason I ask it is this: Is it wise to implement my protocol based on Netgraph (so I can do it as a kernel module), or should I just build it into the kernel? I know; A lot of questions, but I sure need the help :-) (And wouldn't it be cool if we would have IrDA support?)

Re: Mounting a CDROM in freeBSD 4.2
I'd like to thank every one who responded, and all those who were willing to respond but saw that they would be repeating information already sent. It turns out that the designation of the CDROM drive changed between versions 3.3 and 4.2 , and the only one I knew was the designation of the CDROM drive for version 3.3 . I did a grep -i cdrom *.TXT on the files ABOUT.TXT INSTALL.TXT README.TXTTROUBLE.TXT ERRATA.TXTLAYOUT.TXTRELNOTES.TXT UPGRADE.TXT and found no mention of the designation of the CDROM drive, so I am glad that a couple of responders sent it to me. I would like to know how they found out this tidbit of information so I'll know where to look for it in the future. I would suggest that there be a man page listing all the drive designations ( CDROM , A , B [if one has it] , IDE [or other] drive D , etc. , SCSI drives ) and this man page should be referenced as a "SEE ALSO" in all the mount man pages .

Protections on inetd (and /sbin/* /usr/sbin/* in general)
Background: We recently had a customer's web site suffer an attempted exploit via one of their cgi scripts. The attempted exploit involved writing a file into /tmp, then invoking inetd with that file to get a root shell on a non-standard port. While the exploit failed, they were able to write the file as user nobody and invoke inetd. There is not much we can do about that as long as we permit customers to use their own cgi scripts, which is a requirement with this type of account. Issue: The exploit managed to start inetd, camped on the specified port but inetd, properly, failed as soon as it tried to start the service (running as user nobody makes doing setuids difficult :-) Tests by our staff from the command line indicate that any user is able to start inetd with a local config file associating a service with a non standard port. It doesn't WORK but it does attach to the port. Leading to some DOS possibilities, albiet not very interesting ones. Recommendation: A number of the executables located in /sbin and /usr/sbin are never going to be invoked for any legitimate use by anyone other than the superuser. In particular, servers such as portmap and inetd run by non-root users are unlikely to do what was intended. It seems a prudent measure to simply not set execute permission by "other" on such programs during the install, giving the user a handy "Permission denied" message when such an attempt is made. For those reading quickly, I am NOT recommending removing execute permission on ALL of /sbin/* and /usr/sbin/*, only on programs such as "portmap", "inetd", "lpd", "syslogd", "halt", "reboot" and others which perform no useful function to normal users. /sbin/init already enforces this condition, how about expanding it? /\/\ \/\/ To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message

Printing out the whole path to the kernel all the time in syslog messages is
a bit redundant and ugly, especially seeing that it isn't done for any other

Should I send-pr this thing too, or is just sending it to -hackers enough?

Dropping the setuid bit on crontab in favour of a setgid cron alternative also means changing the permissions on the /var/cron/tabs directory which is currently only accessible to root.

Re: ISR not triggered upon the interrupts and OS hangs
Dear Freebsd Hackers, Here is a question regarding my bsd device drivers: I used the pci_map_int() to register an interrupt handler for my PCI device (intline = 12). But when the interrupt comes in, the handler (ISR) is not triggered at all. But the OS hangs and I can see continuous interrupts coming in on the PCI sniffer. You don't use pci_map_int() on any modern version of FreeBSD; you use bus_alloc_resource() and bus_setup_intr(). Since you don't mention which FreeBSD version you're using, it's hard to be of any more assistance. -- ... every activity meets with opposition, everyone who acts has his rivals and unfortunately opponents also.

You could use strrchr(3) here instead of rolling your own loop. However, this
will print out 'kernel' for every kernel. If I 'boot kernel.foo' from the
loader, then the bootfile will be /boot/kernel.foo/kernel, and this will trim
the /boot/kenrel.foo/ part. The kernel.foo part is actually the important
part, however, so I'd prefer it to not do this.

You need only add group read and write permissions for the crontab
group. Since noone is in the crontab group, unless they invoke crontab,
noone will be gaining any "extra" privilege. I also toyed with making
the directory sticky, and adding sanity checks to cron to not invoke
tabs not owned by the user they refer to or root, or at least give
warnings.
FWIW, I had patches to convert 'at' and 'crontab' to being sgid-at
and sgid-crontab ('at' has some really ugly macros that luckily aren't
needed again). I'll probably be doing them again, now that my time is
more sane.
