First I switch the read from /selinux/policy to /selinux/load. Then I undid that change and started generating the in kernel policy buffer on open() rather than on read(). It allowed me to use cat /etc/policy > policy rather than using my own half ass hacked utility. The reason I undid the policy->load change was because I didn't really want to store the old policy on open if they were going to write() a new policy. I can probably make the determination based on the f_mode, but didn't really play with it yet. I try to do both in the next go-round. I'm still trying to figure out what I did to make malformed policies. Must have screwed something up ripping out my prink's and debug hooks, because it isn't working for me now either.... Unrelated note, can we take patches 1,2,3 ? They are just cleanups.... -Eric -- This message was distributed to subscribers of the selinux mailing list.
