Hi,
I have a Linux-dom0 running with Xen. The extraction of the vmcore via
makdumpfile shows the message:
get_xen_basic_info_x86_64: Can't get the symbol of xenheap_phys_end.
The commit 2651d571 changed the behaviour of init_xen_crash_info().
With
- return TRUE;
+ ret = TRUE;
+
+out_error:
+ free(buf);
the buffer is released but it's still used because of
info->xen_crash_info.com = buf;
This leads to random data in the buffer and later to the mentioned
error.
With the change back the memory is not released.
But I'm not familiar enough with code to decide where to do this.
Thanks.
Dietmar.
