Package: libfreeipmi12
Version: 1.1.5-3
Severity: normal
Dear Maintainer,
* What led up to the situation?
Ran a program linked against libfreeipmi2, for example bmc-config.
* What was the outcome of this action?
Segfault:
[ 304.932148] traps: bmc-config[6848] general protection ip:7fa773b714d8
sp:7ffffbda9070 error:0 in libfreeipmi.so.12.0.3[7fa773a13000+29d000]
* What outcome did you expect instead?
No segfault?
The very very strange part of the bug is that this happens the first time
libfreeipmi12 is used after a system boot, not subsequent times.
This is on 3.16-0.bpo.2-amd64, as the Dom0 for xen-4.1. The hardware is a Dell
Poweredge 840.

Hi,
I'm closing this bug: as you found, the crash only happened under Xen,
and upstream agreed it is outside freeipmi, which only uses plain in/out
port I/O after iopl().
The likely cause is the kernel bug fixed as CVE-2016-3157 / XSA-171
(IOPL not properly context-switched on 64-bit PV Xen guests), fixed in
Debian in June 2016 (DLA-516-1, DSA-3607-1).
If you can still reproduce it with a current kernel and freeipmi, please
reopen.
Regards,
Fabio
