Hi,
the attached patches fix various bugs and shortcomings in the CA
management and renewal code. Related tickets:
<https://fedorahosted.org/freeipa/ticket/4416>,
<https://fedorahosted.org/freeipa/ticket/4460>.
(Patch 319 was originally posted at
<http://www.redhat.com/archives/freeipa-devel/2014-September/msg00132.html>.)
Only two of the patches includes what ticket(s) they address. Most have
the tersest of commit messages. If got more and more difficult to see
why the changes were needed at all, as you'll see.
Sorry, fixed (hopefully).
Note that most of these patches fix stuff I didn't have time to fix
before I posted the original CA management patches, hence the missing
tickets.
Well, the policy is that every commit should have a ticket. So I guess
re-open the old tickets or open new ones. This will help someone in the
future know the "why" of a patch. I've certainly been guilty
OK, I will reopen the related tickets.
Here is a new set of reviews as trying to intermingle was making my eyes
cross:
319:
I guess I still don't understand why you can't pull the certs out of
LDAP when creating this database. When this code runs, we know that the
client is configured, so we have access to authentication. Why can't
create_ipa_nssdb pull the certs directly? It seems more robust to me,
and the code is already written in ipa-client-install to do this.
Well, I don't understand why do you want them to be updated so much, as
nothing will break if they are not. Also try to imagine what would
happen if, say, 10k clients were updated at the same moment...
When adding the CA certificates to the temporary database it will report
that a failure occurred, but not the exception:
+ except CalledProcessError, e:
+ root_logger.info("Failed to add CA to temporary NSS database.")
+ return CLIENT_INSTALL_ERROR
Granted, NSS errors are often obtuse, but should it at least DEBUG log it?
It is already logged in ipautil.run. The exception only says that the
command failed, there's no point in logging it.
324, 325, 326: ACK
327:
So the idea is to just mirror the certs and us the new db to know what
was added?
Exactly.
What if someone has the same nickname, different cert in the
two databases? Is that too much of a corner case?
IMO it is too much of a corner case, but I plan on adding a better
diff/patch algorithm in the future if it turns out to be a problem.
328, 329, 330, 331: ACK
As an aside, do you know why the global certs are seen by mod_nss?
libnssckbi.so is symlinked into the directory (certutil -L -d
/etc/httpd/alias -h all will show all the certs).
I'm not sure why it is this way, but the module is linked to the NSS
database:
$ sudo modutil -list -dbdir /etc/httpd/alias

I think the naming and/or comments can be improved. For example, there
are now 3 *retrieve_cert commands, all of which do slightly different
things. All have external handlers (via the oddly named profile), but
some are called internally as well.
I have spent quite some time trying to come up with good names for them,
but I was not able to do so. Suggestions are welcome.
This is rather complex code: a command passes a call onto certmonger
which then exuecutes the IPA CA helper... More documentation would
definitely help a newcomer figure out how renewal, CA retrieval, etc. works.
OK, I'll try to add some.
Not to be too pedantic but there is a lot of this in
dogtag-ipa-ca-renew-agent-submit:
if variable: OR if not variable:
Where variable defaults to None. Shouldn't the test be:
if variable is [not] None:
This doesn't catch empty strings, which may occur in some of these checks.
340: ACK
Through some combination of ipa-certupdate and ipa-cacert-manage I seem
to have hosed things up:

Incidentally, IMHO it should include the command to execute to check the
request manually.
Will add.
The CA is actually unreachable. Restarting it fixed things. I'll chalk
this up to cosmic rays.
OK.
Re-running ipa-cacert-manage renew was successful.
Good.
I confirmed that the CA signing cert was updated in the dogtag database.
I then ran ipa-certupdate to distribute this new CA cert around and none
of the databases got the updated CA cert, nor did /etc/ipa/ca.crt.
Can you see the new CA cert in cn=certificates,cn=ipa,cn=etc,$SUFFIX?
Still doing some functional testing.
