Actual Results:  12 lines in /var/log/messages with "avc: denied", all

Created attachment 104090 [details]
grep "avc:" /var/log/messages  # plus all selinux-related lines, to show context

I see 12 lines with avc: complaints.
Comment 2 Daniel Walsh 2004-09-22 10:13:53 EDT
THis is caused because the tmpfs xattr patch was pulled from the
kernel.  Please use the previous kernel (FC3-T2 kernel) until we have
this sorted out.

Comment 3 Warren Togami 2004-10-09 18:24:39 EDT
kernel-2.6.8-1.541 is supposed to have tmpfs + xattrs.  The next
working tmpfs + xattrs kernel was 598+.  Reiser mentions "permissive"
mode.  Are the xattrs being set properly in permissive mode?
Comment 4 John Reiser 2004-10-09 19:51:40 EDT
I see no complaints when booting to targeted, permissive mode using:
The /var/log/messages at boot has:
  Oct  9 16:44:38 localhost kernel: SELinux: initialized (dev tmpfs,
type tmpfs), uses transition SIDs
[I stopped running up2date on Oct.4 because my reading of
fedora-test-list convinced me that FC3test2 had entered a phase of
instability that was more than I wanted to handle.]
Comment 5 Daniel Walsh 2004-10-09 21:02:15 EDT
Fixed with latest kernel (603) and policy-1.17.29-1.  
Comment 6 Colin Walters 2004-10-15 13:11:01 EDT
Yeah, we can mark this as fixed.
