Thanks for the help, but
[root@localhost ~]# grep insmod /var/log/audit/audit.log | audit2allow -M myinsmod
compilation failed:
sh: /usr/bin/checkmodule: No such file or directory
[root@localhost ~]# semodule -i myinsmod.pp
semodule: Could not read file 'myinsmod.pp':
[root@localhost ~]#
which packages should I have to install in order for this to work?

Antonio

That would help just with the ~xguest part of the enhancements but this
change is really simple and doesn't affect much of the code.
However the temp dir part must be handled in the module directly. The
only change could be instead of calling 'rm -rf' directly to call
something like namespace.remove script. But as the only logical thing is
to remove the temporary directory anyway I don't think it is worth the
hassle.

Ok the avc

Looks like the interesting one. The rest were caused by you doing a restorecon -R -v /, or the original mislabeling of /root.
What node is insmod trying to create in /dev? Do you have any idea what is going on here?
This is very strange that you would get this avc since insmod_t is supposed to be unconfined in FC-7
Also
Thank you for responding. Indeed it is the mknod entry that is causing trouble. I use smartlink modem and thus I have added to /etc/modprobe.conf
alias char-major-243 slusb
alias char-major-242 slamr
install slamr modprobe --ignore-install ungrab-winmodem ; modprobe --ignore-install slamr; test -e /dev/slamr0 || (/bin/mknod -m 660 /dev/slamr0 c 242 0 2>/dev/null && chgrp dialout /dev/slamr0)
so that I do not have to type as root user (su -) modprobe ungrab-winmodem, modprobe slamr, slmodemd -c USA /dev/slamr0 everytime I start up the computer. This is for automation. As a result of this denied avc, automation of loading slamr module fails.
This is the only one now causing trouble

How should I tackle this one, without disabling selinux, or setting it to permissive?
Thanks,

mknod denials, avcs from dmesg please help
by Antonio Olivares
Dear Selinux experts,
I have successfully loaded Fedora 7 on a machine that refused to boot it with a kernel panic. I am on track with it but selinux is getting in my way.
I have done
[root@localhost ~]# restorecon -v /
[root@localhost ~]# touch /.autorelabel; reboot
three times and still these avcs refuse to go away.
Summary
SELinux is preventing access to files with the default label, default_t.
Detailed Description
SELinux permission checks on files labeled default_t are being denied.
These files/directories have the default label on them. This can indicate a
labeling problem, especially if the files being referred to are not top
level directories. Any files/directories under standard system directories,
/usr, /var. /dev, /tmp, ..., should not be labeled with the default label.
The default label is for files/directories which do not have a label on a
parent directory. So if you create a new directory in / you might
legitimately get this label.
Allowing Access
If you want a confined domain to use these files you will probably need to
relabel the file/directory with chcon. In some cases it is just easier to
relabel the system, to relabel execute: "touch /.autorelabel; reboot"

Summary
SELinux is preventing /bin/mknod (insmod_t) "write" to / (device_t).
Detailed Description
SELinux denied access requested by /bin/mknod. It is not expected that this
access is required by /bin/mknod 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 /, restorecon -v / 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
http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385 Or you can disable
SELinux protection altogether. Disabling SELinux protection is not
recommended. Please file a http://bugzilla.redhat.com/bugzilla/enter_bug.cgi
against this package.

Samba log files have wrong context?
by Bob Kashani
SELinux keeps complaining that the file contexts for log files
in /var/log/samba are wrong. All of the files are labeled samba_log_t
but it seems to want samba_share_t, is this correct?
This is what selinux troubleshooter reports:
Summary
SELinux is preventing samba (/usr/sbin/smbd) "append" to log.chaucer
(samba_log_t).
Detailed Description
SELinux denied samba access to log.chaucer. If you want to share
this
directory with samba it has to have a file context label of
samba_share_t.
If you did not intend to use log.chaucer as a samba repository it
could
indicate either a bug or it could signal a intrusion attempt.
Allowing Access
You can alter the file context by executing chcon -R -t
samba_share_t
log.chaucer
The following command will allow this access:
chcon -R -t samba_share_t log.chaucer
Additional Information
Source Context system_u:system_r:smbd_t
Target Context system_u:object_r:samba_log_t
Target Objects log.chaucer [ file ]
Affected RPM Packages samba-3.0.25-2.fc7 [application]
Policy RPM selinux-policy-2.6.4-8.fc7
Selinux Enabled True
Policy Type targeted
MLS Enabled True
Enforcing Mode Enforcing

Udev AVC spawning a script
by Aurelien Bompard
Hi,
I comaintain synce (a framework to connect to PocketPC devices) in Fedora,
and since Fedora 7 it does not autoconnect the device when plugged in.
Autoconnection is done by an Udev rule :
# cat /etc/udev/rules.d/60-synce.rules
ACTION=="add", SUBSYSTEM=="usb_device", SYSFS{idVendor}=="0bb4",
SYSFS{idProduct}=="0a06", SYMLINK+="ipaq",
RUN+="/usr/bin/synce-serial-start"
synce-serial-start is a shell script that sources a
file: /usr/share/synce/synce-serial-common
On F7, I get AVC messages for getattr and read permissions from
synce-serial-start to this file:
type=AVC msg=audit(1180872169.345:3815): avc: denied { getattr } for
pid=31270 comm="synce-serial-st" name="synce-serial-common" dev=sda2
ino=438256 scontext=system_u:system_r:udev_t:s0-s0:c0.c1023
tcontext=system_u:object_r:usr_t:s0 tclass=file
type=AVC_PATH msg=audit(1180872169.345:3815):
path="/usr/share/synce/synce-serial-common"
type=AVC msg=audit(1180872169.345:3816): avc: denied { read } for
pid=31270 comm="synce-serial-st" name="synce-serial-common" dev=sda2
ino=438256 scontext=system_u:system_r:udev_t:s0-s0:c0.c1023
tcontext=system_u:object_r:usr_t:s0 tclass=file
How should I label /usr/share/synce/synce-serial-common to allow access from
udev_t ?
And in general, how can I view which labels are allowed (and in which way)
for a given type ?
Thanks !
Aurélien

AVC from dhclient on boot....
by Tom London
Seeing this for the last few days on Rawhide:
Jun 2 12:24:36 localhost kernel: e1000: eth0: e1000_watchdog: NIC
Link is Up 100 Mbps Full Duplex, Flow Control: RX/TX
Jun 2 12:24:36 localhost kernel: e1000: eth0: e1000_watchdog: 10/100
speed: disabling TSO

scontext=system_u:system_r:dhcpc_t:s0
tcontext=system_u:object_r:setfiles_exec_t:s0 tclass=file
Not sure where this comes from.
There is a call to 'cp -fp', could that be it?

Fedora 7 nvidia issues

Hi, folks. I'm having a few issues with nvidia on a fresh install of F7.
