Hi,
I noticed that as of a recent rawhide update that Eclipse stopped working:
audit(1108057938.336:0): avc: denied { execmem } for pid=14065 comm=eclipse scontext=user_u:system_r:unconfined_t tcontext=user_u:system_r:unconfined_t tclass=process
Chatting with Dan, this is apparently because the execmem permission was dropped from unconfined_domain recently.
We can't do this in targeted policy because it would require us to know about (and specially label) all such programs. We could potentially label /usr/bin/eclipse as unconfined_execmem_t or whatever since we have Eclipse packages in Fedora. However, I am almost positive the Sun JVM requires this permission too, and if we go this route, then every person who untars the Sun JVM and tries to run Java programs will run into this problem.
This is against the philosophy of the targeted policy in that it affects programs outside of the targeted daemon set. My worry is that for every person (like me) who tracks down this problem and finds a workaround, there will be 999 others who disable SELinux entirely. And that's bad, because we need it to be enabled by default so we can use it to confine the programs that really need it.
(Dan says that textrel_shlib_t has a similar issue)
One approach might be to have e.g. bin_t and bin_nonexecmem_t. We label programs that we know work as bin_nonexecmem_t.
