[uml-user] Various applications getting segfaults

[Martin G. <gro...@bb...>]

My hosts (100) are all running 2.4.35 with skas3 and all UML patches.  
My UMLs (guests) are all running
2.4.35 with all UML patches.  I'm testing OSPF and PIMD (within the 
UMLs).  Every UML boots fine
and all applications start fine.  All OSPFs converge, and all RPs and 
BSRs (PIMD) are fine.  Once I start
mgen traffic (Multicast) a few OSPFs start getting segmentation faults.  
Other weird things start happening.....

1) Once in 1 UML /bin/bash was core dumping every time it ran.  I could 
see this by killing the UML and
     mounted to rootfs via loopback.  /bin/bash (after a loopback mount) 
had the correct checksum.

2) Twice the "WC" program woulc always get a segfault yet once the UML 
was down and rootfs mounted via
    loopback the "WC" binary had the correct checksum.

3) SSHD inside the UMLs sometimes imm close incoming connections yet 
stays running.  If I kill off sshd and
    restart it, it imm dies.

4) OSPFs are getting segfaults in all sorts of places.  Its as if the 
memory (code/stack) is getting corrupted.

subroutine A calls subroutine B and gets a segfault pushing the middle 
argument.....

subB( oi, node->a, node->b)

using GDB node is a valid pointer and its already pushed node->b onto 
the stack and gets a segfault
when pushing node->a onto the stack.  node is in %ebx, and is valid, and 
both %ebp and %esp are
also valid.
