Thanks Jeff, all seems to work ok now.
It runs in skas 4:
Locating the top of the address space ... 0xc0000000
Core dump limits :
soft - 0
hard - NONE
Checking that ptrace can change system call numbers...OK
Checking syscall emulation patch for ptrace...OK
Checking advanced syscall emulation patch for ptrace...OK
Checking for tmpfs mount on /dev/shm...OK
Checking PROT_EXEC mmap in /dev/shm/...OK
Checking for SKAS4 support in the host:
/proc/self/mm ... OK
new_mm ... OK
switching over ... switched back ... OK
PTRACE_SWITCH_MM ... OK
Full CPU fault information in siginfo_t ... OK
Full CPU fault information in PTRACE_GETSIGINFO ... OK
vcpu ... Host TLS support detected
Detected host type: i386
(GDT indexes 6 to 9)
OK
UML running in SKAS4 mode
...
And stop & go works fine too:
uml_mconsole uml_test
(uml_test) stop
OK stopped
(uml_test) go
OK
(uml_test)
Thanks,
Benedict
