You can get the most of these printfs using dtrace fbt probes.
To get more, I prefer add ICMP_PROBE() dtrace probe, similar to that we have
for IP, UDP and TCP.

[Bug 204568] gif(4) interface remembers configuration after being destroyed

Creating the gif1 interface triggers a LINK_UP event on /dev/devctl and the
default devd configuration reacts to this event by running /etc/rc.d/netif
start $interface.  

Please provide the output of `grep gif1 /etc/rc.conf`.

Thanks for the insight. However, I just tried the patch proposed and it still

[Bug 204602] parse() in boot loader interp_parse.c is too naive about quotes

[bugzilla-noreply]

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=204602

Bug ID: 204602
   Summary: parse() in boot loader interp_parse.c is too naive
about quotes
   Product: Base System
   Version: 11.0-CURRENT
  Hardware: Any
OS: Any
Status: New
  Severity: Affects Some People
  Priority: ---
 Component: kern
  Assignee: freebsd-bugs@FreeBSD.org
  Reporter: tso...@me.com

Created attachment 163200
  --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=163200=edit
udiff of inter_parse.c

current logic how the quotes (both ' and ") are managed is a bit too relaxed,
allowing wierd constructs like set name="value' also usual single quote
semantics is not possible and, the code does not check if the quoted string
actually has ending quote.

I'm adding here diff for possible update, which implements:

1. distinguishing single and double quote
2. variable expansion will not be done inside single quote protected area
3. will preserve inner quote for values like "value 'some list'"
4. ending quote check.

however, this diff does not implement ending quote order check - it shouldn't
be too hard, needs some improvements on parser state machine.

--- Comment #4 from Rick Macklem  ---
Created attachment 163217
  --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=163217=edit
Patch to fix sg_threadcount++ so the mutex is held when done

I took a closer look at svc.c and the only way that the race
I think might have happened can occur is if svc_run() doesn't
wait for all threads to terminate. I also can now see that the
first patch wouldn't have fixed anything, so I'm not surprised
it didn't work.

The only thing I can see that is broken in the code and might
allow svc_run() to return before all threads have terminated is:
- The thread count sg_threadcount is incremented when the sg_lock
  mutex isn't held.
  --> This could conceivably result in a corrupted sg_threadcount,
  which would allow svc_run() to return before all threads have
  terminated.

This second patch fixes the code so that sg_threadcount++ is always
done when the sg_lock mutex is held.

If you can test this one instead of the last one, that would be
appreciated. I do know this patch fixes the above problem, but I
don't know if this is the cause of your crashes.

Also, this bug seems to have existed in the code forever and all
that r267228 did was switch from not holding the pool mutex to
not holding the group mutex. So Alexander, you are off the hook,
I think.;-) I've left you on the cc, since you probably know this
code better than anyone else and might have some insight w.r.t. this crash.

10.2-stable unified diff for /usr/src/sys/netinet/ip_icmp.c

Currently it only possible to follow IPv4 ICMP handling in/of the kernel by
recompiling the kernel and adding a define for "ICMPPRINTFS" to enable kernel
console messages for ICMP handling in /usr/src/sys/netinet/ip_icmp.c.

The attached patch converts this into a sysctl variable
"net.inet.icmp.log_icmps" to enable/disable debugging output without
recompilation.

As an add-on, the FIB number is displayed for rx'd/tx'd ICMP packets.

Just a me too...

The hardware is an Acer TM-B113:

agp0:  on vgapci0
agp0: aperture size is 256M, detected 131068k stolen memory
info: [drm] Initialized drm 1.1.0 20060810
drmn0:  on vgapci0
info: [drm] MSI enabled 1 message(s)
info: [drm] AGP at 0xb000 256MB

I'm running 10.1/amd64 with:
libdrm-2.4.65_1,1
xf86-video-intel-2.21.15_9
xorg-server-1.17.4,1



The hang has started recently (or at least its incidence has increased a lot).
There is no day I can work with this laptop without one/two hangs.


This is very annoying, so I'm looking for help on one side and offering to do
any testing on the other.
Thanks.
