Re: IGMP fragmentation bug - another behavior

Hi all.

I've compiled kod.c on Solaris SPARC 2.6:
SunOS 5.6 Generic_105181-12 sun4u sparc SUNW,Ultra-1
with gcc 2.8.1

after executing kod to some win host Solaris hme driver has been choked and was in
nonoperational mode about 1 min. After this hme interface was reinitialized:

SUNW,hme0: Link Down - cable problem?
SUNW,hme0: Link Down - cable problem?
SUNW,hme0: Link Down - cable problem?
SUNW,hme0: Using Internal Transceiver
SUNW,hme0: 100 Mbps half-duplex Link Up

and machine continues work without problems.

Only root user is able to execute kod. kod output is:

Determining max MSGSIZE
Max MSGSIZE is 15000
..15000 bytes [HOST:PORT]..


Same behavior on Solaris 7 SPARC/E250 with binaries produced by gcc and
Sun Workshop 5.0 cc compilers.

Solaris 7 is:
SunOS 5.7 Generic_106541-05 sun4u sparc SUNW,Ultra-250

But on SPARCstation 4 Model 110 with le card there are no problems with executing
kod. Interface not frozen... Also target win host machine continues normal work.

Solaris 7 on SS4 is same:
SunOS 5.7 Generic_106541-05 sun4m sparc SUNW,SPARCstation-4

So looks like kod affects bug in Solaris 2.6/7 hme driver.
