Description Bryan Agee 2007-04-11 21:38:16 UTC
Description of problem:
bluez-utils attempts to read inotify during update, which is not allowed be the
default SELinux policies.

The following is the SELinux Troubleshooter report:

    SELinux is preventing /usr/sbin/hcid (bluetooth_t) "read" to inotify

Detailed Description
    SELinux denied access requested by /usr/sbin/hcid. It is not expected that
    this access is required by /usr/sbin/hcid and this access may signal an
    intrusion attempt. It is also possible that the specific version or
    configuration of the application is causing it to require additional access.

Allowing Access
    Sometimes labeling problems can cause SELinux denials.  You could try to
    restore the default system file context for inotify, restorecon -v inotify
    If this does not work, there is currently no automatic way to allow this
    access. Instead,  you can generate a local policy module to allow this
    access - see Or you
    can disable SELinux protection altogether. Disabling SELinux protection is
    not recommended. Please file a against this package.

Comment 1 Matthew Miller 2007-04-12 12:58:38 UTC
Although it's far from obvious, all Fedora 7 test bugs should be filed against
"devel", not "test#". Moving this, so it doesn't get lost.

This has been a bulk message. We return you now to your regularly scheduled
program, already in progress.

I was also hit by this. There is a hint to fix it in the "allowing Access" section:

> Allowing Access

This worked for me - as root:
    restorecon -v /proc/sys/fs/inotify

I have no idea why it works, because apparently there is not security context on
the directory:

ls -dZ /proc/sys/fs/inotify
dr-xr-xr-x  root root                                  /proc/sys/fs/inotify

(this is on fc7-devel with all updates)
