Just a heads up. If you do want to use the nVidia installer with SELinux
enabled, the instructions on the FedoraFaq web site need to be updated.
The changes I suggested on f-s-l were to avoid globally allowing
execstack/execmod, and limiting this to those objects that actually
needed it. The approach suggested in fedorafaq works, but could be more
securely done.
Undo the changes to the booleans:
# /usr/sbin/setsebool -P allow_execstack 0
# /usr/sbin/setsebool -P allow_execmod 0
ran these and immediately got a prompt with no messages
Then update the file contexts instead:
# /usr/sbin/semanage fcontext -a -f -- -t textrel_shlib_t
'/usr/lib/libGL(core)?\.so(\.[^/]*)*'
Running each of the next three produced readout that seemed to indicate errors
in syntax - i.e. instructions for proper running of the command:
/usr/sbin/semanage fcontext -a -f -- -t textrel_shlib_t'/usr/lib/libGL(core)?
\.so(\.[^/]*)*'
semanage {login|user|port|interface|fcontext|translation} -l [-n]
semanage login -{a|d|m} [-sr] login_name
semanage user -{a|d|m} [-LrRP] selinux_name
semanage port -{a|d|m} [-tr] [ -p protocol ] port | port_range
semanage interface -{a|d|m} [-tr] interface_spec
semanage fcontext -{a|d|m} [-frst] file_spec
semanage translation -{a|d|m} [-T] level
Space missing between textrel_shlib_t and
'/usr/lib/libGL(core)?\.so(\.[^/]*)*'
# /usr/sbin/semanage fcontext -a -f -- -t textrel_shlib_t
'/usr/lib/libnvidia.*\.so(\.[^/]*)*'
Running this command yielded similar results as just above, and in this case
there is no file/directory named "/usr/lib/libnvidia" - the same for the next
command
# /sbin/restorecon -v /usr/lib/libGL* /usr/lib/libnvidia*
In case of line wrapping, each of the three commands above should be on
a single line.
The above is based upon a discussion with Paul Howarth on the SELinux list
I'm running the nvidia rpms from Livna - there is a folder
called "/usr/lib/nvidia" which has "*.so" files in it; could this be what you
mean for the last two commands? That still wouldn't account for the problem
with "/usr/lib/libGL", however...
The advice I gave to Mark was based on his use of the nvidia installer
directly; the file contexts for a properly-packaged RPM like the one
from livna will be different because the files will be somewhere else
(and the context fixes might even be done in the RPM itself; I don't know).
