Package: libice6
Version: 2:1.0.5-1
Severity: normal
Tags: patch
I'm using Debian sources but not Debian binaries.
When I run xsm (x11-session-utils 7.3+1) from ~/.xsession,
it creates several sockets and listens to them. The file
descriptors it opens for these sockets get pointlessly inherited
by child processes, causing warnings from LVM2 utilities.
xsm should make the file descriptors close on exec.

To create these sockets, xsm uses libICE, which in turn uses
source code from xtrans. In X11 Release 6 Public Patch #08
<http://www.umich.edu/~archive/x11/r6-src/fixes/fix-08>,
IceAcceptConnection() and IceOpenConnection() were changed to
call _IceTransSetOption (newconn, TRANS_CLOSEONEXEC, 1); but
IceListenForConnections() does no such thing. Because libICE
apparently expects callers to access the listening sockets only
via the opaque typedef struct _IceListenObj *IceListenObj, and
these structures do not survive the address-space change in exec,
I don't think it makes sense to keep the file descriptors open
across exec either.
libice (2:1.0.5-1.kon.1) local; urgency=low
* Local version!
* Make the sockets opened by IceListenForConnections close on exec.
This stops xsm from leaking the $SESSION_MANAGER sockets to all the
processes in the session.
