Works for me, but I have some questions (this is an area I know
little
about).
Can we be 100% sure these certs are always renewed together? Is
certmonger the only possible mechanism to update them?
You raise a good point. If though some mechanism someone replaces
one of
these certs it will cause the script to fail. Some notification of
this
failure will be logged though, and of course, the certs won't be
renewed.
One could conceivably manually renew one of these certificates. It is
probably a very remote possibility but it is non-zero.
Can we be sure certmonger always does the updates in parallel? If it
managed to update the audit cert before starting on the others, we'd
get
no CA restart for the others.
These all get issued at the same time so should expire at the same
time
as well (see problem above). The script will hang around for 10
minutes
waiting for the renewal to complete, then give up.
The certs might take different amounts of time to update, right?
Eventually, the expirations could go out of sync enough for it to
matter.
AFAICS, without proper locking we still get a race condition when the
other certs start being renewed some time (much less than 10 min) after
the audit one:
(time axis goes down)
audit cert other cert
---------- ----------
certmonger does renew .
post-renew script starts .
check state of other certs: OK .
. certmonger starts renew
certutil modifies NSS DB + certmonger modifies NSS DB == boom!
This can't happen because we count the # of expected certs and wait
until all are in MONITORING before continuing.
The problem is that they're also in MONITORING before the whole renewal
starts. If the script happens to check just before the state changes
from MONITORING to GENERATING_CSR or whatever, we can get corruption.
The worse that would
happen is the trust wouldn't be set on the audit cert and dogtag
wouldn't be restarted.
The state the system would be in is this:
- audit cert trust not updated, so next restart of CA will fail
- CA is not restarted so will not use updated certificates
And anyway, why does certmonger do renewals in parallel? It seems
that
if it did one at a time, always waiting until the post-renew
script is
done, this patch wouldn't be necessary.
From what Nalin told me certmonger has some coarse locking such that
renewals in a the same NSS database are serialized. As you point
out, it
would be nice to extend this locking to the post renewal scripts. We
can
ask Nalin about it. That would fix the potential corruption issue.
It is
still much nicer to not have to restart dogtag 4 times.
Well, three extra restarts every few years seems like a small price to
pay for robustness.
It is a bit of a problem though because the certs all renew within
seconds so end up fighting over who is restarting dogtag. This can cause
some renewals go into a failure state to be retried later. This is fine
functionally but makes QE a bit of a pain. You then have to make sure
that renewal is basically done, then restart certmonger and check
everything again, over and over until all the certs are renewed. This is
difficult to automate.
So we need to extend the certmonger lock, and wait until Dogtag is back
up before exiting the script. That way it'd still take longer than 1
restart, but all the renews should succeed.
Right, but older dogtag versions don't have the handy servlet to tell
that the service is actually up and responding. So it is difficult to
tell from tomcat alone whether the CA is actually up and handling requests.
Revised patch that takes advantage of new version of certmonger.
certmonger-0.65 adds locking from the time renewal begins to the end of
the post_save_command. This lets us be sure that no other certmonger
renewals will have the NSS database open in read-write mode.
We need to be sure that tomcat is shut down before we let certmonger
save the certificate to the NSS database because dogtag opens its
database read/write and two writers can cause corruption.

Subject: [PATCH] Use new certmonger locking to prevent NSS database
corruption.
dogtag opens its NSS database in read/write mode so we need to be very
careful during renewal that we don't also open it up read/write. We
basically need to serialize access to the database. certmonger does the
majority of this work via internal locking from the point where it generates
a new key/submits a rewewal through the pre_save and releases the lock after
the post_save command. This lock is held per NSS database so we're save
from certmonger. dogtag needs to be shutdown in the pre_save state so
certmonger can safely add the certificate and we can manipulate trust
in the post_save command.
Fix a number of bugs in renewal. The CA wasn't actually being restarted
at all due to a naming change upstream. In python we need to reference
services using python-ish names but the service is pki-cad. We need a
translation for non-Fedora systems as well.
Update the CA ou=People entry when he CA subsystem certificate is
renewed. This certificate is used as an identity certificate to bind
to the DS instance.
