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.
