Thank you very much for the review. I'll send out updated patches.
Attached are patches that implement the corrections Simo and Pavel asked
for with the exception of confdb being read-only for sssd processes,
Michal is still investigating that one.
I also merged some more Michal's patches that help spawn the PAM
privileged pipe before dropping privileges and also dropping privileges
in the other responders.
With this patchset, all responders are able to run as the SSSD user.
I have one question:
is it wise to also set the permissions of directories we create when
we "install -d" them? Or is this something typically done by the
downstream? Previously, we would just rely on the default system umask
when running "make install", maybe we should tighten the permissions in
Makefile.am as part of this effort?
And one comment:
One of Michal's patches moves creating the socket into a separate
function. This function also changes the umask, which I don't think
belongs into a utility function. I realize this is how the code worked
even before Michal's change, but I think it would be better to move the
umask setting into function like sss_process_init().
Thanks again for the review.
