The next obstacle is that gdbserver-xen is segfaulting upon connection I actually meant when you gave it an invalid domain id, but that isn't a key issue ... #0 0x40021fb4 in map_domain_va () from /usr/lib/libxenctrl.so.3.0 That is a rather strange place for it to be blowing up. In the past there were cases where it would blow up in xc_ptrace when it tried to dereference an address that had not been successfully mapped to. In principle using alloca could bite you if len were so long that you ran off your stack, but you have a small stack and you're only reading 8 bytes. I'll see if I can determine any more by spelunking at the assembly level. Just to confirm that I'm looking at the same code, is your line 394: buffer[i] = myptrace (xc_handle, PTRACE_PEEKTEXT, inferior_pid, (PTRACE_ARG3_TYPE) addr, 0); _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
