Bug 467210

Are you certain you don't have any 3rd party software installed... say like an X driver or something? :)

What Rex says, plus does "ldd knotify4" show anything unusual (like libraries outside of /usr/lib)?

Oops, make that:
ldd /usr/bin/knotify4

Yes.  Default install no binary drivers.  I can't boot to computer again.  I need a fix fsck or something to get back up and running.

Odd, I can't reproduce this.  I'll keep looking tho.

Corrupt file system? That might be what's causing this problem, too.

Definely not an SELinux bug then?

From selinux list commentary on this bug:

The unix_stream_socket is a leaked file descriptor.

node=localhost.localdomain type=AVC msg=audit(1224873233.717:83): avc:
denied  { read write } for  pid=3912 comm="ip" path="socket:[11145]"
dev=sockfs ino=11145 scontext=unconfined_u:system_r:ifconfig_t:s0
tcontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
tclass=unix_stream_socket

These can be dontaudited or allowed using

# grep ifconfig /var/log/audit/audit.log | audit2allow -m mypol
# semodule -i mypol.pp

Probably a bug in one of the kde routines that should be calling
fcntl(fd, F_SETFD

That is a different issue though. This bug is about an executable stack, it has nothing to do with leaked file descriptors.

Here's the reference:
https://www.redhat.com/archives/fedora-test-list/2008-October/msg01248.html

It would appear Dan made an incorrect conclusion here, reclosing... at least until we have more evidence, receive confirmation from elsewhere, or are able to reproduce this.

Antonio, we're still waiting to see output form ldd, per comment #3 , which may help id the problem.

Gone for the weekend :)

Sorry for not sending it in before.
