Re: -current hangs during boot

[Donny Lee]

   
 John W. De Boskey noticed me some points to check out,
 I now can boot my fbsd box with the recent built kernel.

 I disabled mfs, and random_load, these 2 made my fbsd box
 hangs (not really hangs, it looks like waiting for some 
 jobs done) 2 times at boot. 

 with the mfs enable, it hangs there right after FILESYSTEM
 checking, and with random_load set to YES, it hangs at ldconfig.

Re: newfs/fsck problem (bad superblocks)

[Tor . Egge]

 Reverting src/sbin/newfs/mkfs.c to revision 1.29 fixes
 the problem.
 
 With just a quick review of the patch, I'm not sure I
 understand what forces the last dirty buffer to be
 written.
 
 revert the patch? try to fix it? comments?

Try the enclosed patch.  It flushes the dirty buffer before
program exit and before reading blocks.

Re: -current hangs during boot

[Makoto MATSUSHITA]

leifn My hangs at loading ldconf. I can continue with ^C.

Are you using MFS ? I suppose you are not.

I've found that:

- if /etc/fstab has 'mfs' line, system stops during mounting
  filesystem. Interrupting with CTRL-C works (and system goes to
  single user mode).

- if /etc/fstab does not have 'mfs' line, system stops during ldconfig.
  Also interruptable. System is working (you can login from console),
  but something goes wrong (network interface doesn't work).

Your case is the latter one, and previous email you have mentioned is
the former one.

I can reproduce both cases with a -current box cvsuped two days before.

Don't forget to consider how you could do this with netgraph.
We already have ppp over ethernet and other  transports using netgraph,

I am not familiar with netgraph  could you point me to some info?

The hardest part from my perspective is finding the info for the drivers
for the ATM
(I assume you mean ATM as used in DSL) DSL cards.
We already have some ATM support so it would be a case of just
working out how to best hook it all together, preferably with netgraph
as the framework
to do so.

Well it is for DSL but, the adapter he has is already supported by FreeBSD.
Just the PPP over ATM is an issue.

test from mysql's configure

[Andrey Rouskol]

Hi there !

Some days ago I was tring to compile mysql at -current and found that 
./configure freezes at 'checking for restartable system calls'. Here is a
code witch is executed - if you compile it with '-lc_r -lm -lcrypt' it will
freeze.

test.c:

/* Exit 0 (true) if wait returns something other than -1,
   i.e. the pid of the child, which means that wait was restarted
   after getting the signal.  */
#include sys/types.h
#include signal.h
ucatch (isig) { }
main () {
  int i = fork (), status;
  if (i == 0) { sleep (3); kill (getppid (), SIGINT); sleep (3); exit (0); }
  signal (SIGINT, ucatch);
  status = wait(i);
  if (status == -1) wait(i);
  exit (status == -1);
}

/* end of code */

Regards,

Andrey.

Yes, I can repeat this problem also.  I haven't figured it out yet, but

works:

#include sys/types.h

  int i = fork (), status, mask[20];
  if (i == 0) { sleep (3); kill (getppid (), SIGINT); sleep (3); exit

Ok, well if I were to netgraphify the ATM code, would mpd be sufficient
to get PPP over ATM working?  (I have a lot of reading up to do, but
if I can decide on the correct direction to start off in I could save myself
alot of time ;)).  And for the record I have done ethernet drivers in Linux
and OS/2.   But I am quite unfamiliar with the FreeBSD networking code.
I have only submitted patches to the kernel for cyrix code optimizations. :)

I looked into netgraph and it seems to be a very modular and a wise
approach to take if it sufficient for this purpose.

 Exactly. Except not just after make world/kernel, every time you 
 want to reboot/halt.

  Does this make any different? 

  shutdown is fine, but ctrl-alt-del is not so good,
  whenever I did this, the next boot takes a long time on
  fixing filesystems.

Re: Junior Kernel Hacker Task: M_ZERO

[David Malone]

 Now, if one or two people will review this patch and verify that
 LINT  GENERIC kernels compile the same, we're set for commit...

It works fine with GENERIC - atleast I tested a buildworld with
sources build with it. I don't think LINT compiles at the moment,
atleast it seems to get stuck in the midway driver. I'll have a
look at it this evening.

One other think I wanted to do was seperate out the bits of the
patch which touches code shared among the BSDs (KAME in particular).
We should probably check with the owners of the code before we
touch it, as it is a sort of "cosmetic" change. OTOH, it seems like
something which could be useful for all the BSDs, as it provides
the memory allocation system with a better idea of the demand for
various types of memory.

What about using something like

#if defined(__FreeBSD__)  __FreeBSD_version = 5x

This would probably make it easier for multi OS code, and also make 
it easier to MFC some of the affected code into -stable ??

divert as module?

[Leif Neland]

I want to install ipfw and natd to a machine working as isdn-router, which I
lost the kernel config for
I connect to the world via userland-ppp and isdnd.

I don't have any ipfw or divert compiled in the kernel, but I can load
ipfw.ko, so the firewall rules can work (I now see my isp sends IGMP's to
me...)

I can also start /sbin/natd -n ed0

But the command
"ipfw add divert natd all from any to any via tun0 "
fails:
0 divert 8668 ip from any to any via tun0
ipfw: setsockopt(IP_FW_ADD): Invalid argument

And I can't get from any hosts inside the router to the world.

Can I enable divert via a module, or do I have to reconstruct the kernel
config and recompile?

Or can I use ppp's nat together with ipfw?

I have used the http://www.freebsd.org/tutorials/dialup-firewall/index.html
by Marc Silver as the basis for my setup.

# kldstat
Id Refs AddressSize Name
 15 0xc010 250bf8   kernel

You mean your system doesn't unmount the disks at ctrl-alt-del? Does it a

No it shouldn't.

 And because I had the GNU m4 installed as m4 and not gm4 the building
 of the boot blocks went belly up (bootblocks crashed on boot).

Then DON'T DO THAT.  There is a reason the GNU M4 port installs it as
`gm4'.

   I saw this the other day...

   I've been examining the mfs code, and I'm not really sure why
it needs to use random values...

   Anyone know the history on the '#ifdef FSIRAND' code?

ps: break out of the boot sequence, 'ls -al /etc/  /dev/random'
and then 'exit' will get around this and other problems, but
requires hands on reboots.

  H.  I must confess that I see /etc as getting rather cluttered
  these days.  Is there no way to perhaps collapse some of the most
  related functionality into single files and start passing arguments
  or something?  Just a comment..

 At BSDcon Luke M showed me what the NetBSD 1.5 rc files look like.
 They've moved them all to /etc/rc.d/ and made them very granular
 (as SVR4, but w/o leading numbers in the filenames). The NetBSD
 implementation also solved all the issues people have brought up
 in the past -- dependacies, etc...

 We should just move to using their rc code.

One of the reasons for the numbers in the SysVR4 arena is to
set the order of execution so programs which other depend upon
are executed first.  How does the NetBSD solve this problem.

 Ok, well if I were to netgraphify the ATM code, would mpd be sufficient
 to get PPP over ATM working?  (I have a lot of reading up to do, but

Mpd can do PPP over any netgraph hook, so unless there's some particular
weirdness to the framing of PPP frames over ATM, it should more or less
just work... Quoting from ng_ppp(4):

These device-independent hooks transmit and receive full PPP
frames, which include the PPP protocol, address, control, and
information fields, but no checksum or other link-specific fields.
