Python ifaddr is an alternative to netifaces, is currently maintained,

This patch modifies FreeIPA to rely on ifaddr instead of neitfaces, due

Issue 8384 introduced a new installation state for the statestore
to identify when client/server installation is completely finished
rather than relying on has_files().
The problem is that ipa-client-automount may be called during
ipa-client-install and since installation is not complete at that
point the automount install was failing with "IPA client not
configured".
Add a new state, 'automount', to designate that automount installation
is in process. If check_client_configuration() fails it checks to
see if [installation] automount is True. If so it continues with the
installation.
This also addresses an issue where the filestore and statestore are
shared between the client and automount installers but the client
wasn't refreshing state after automount completed. This resulted in
an incomplete state and index file of backed-up files which caused
files to not be restored on uninstall and the state file to be
orphaned.

The client installer code can be called in 3 different ways:
- from ipa-client-install CLI
- from ipa-replica-install CLI if the client is not already installed
- from ipa-server-install
In the last case, the client installer is called with
options.on_master=True
As a result, it's skipping the part that is creating the krb5
configuration:
if not options.on_master:
nolog = tuple()
configure_krb5_conf(...)
The configure_krb5_conf method is the place where the krb5.conf file is

The ``ipa-client-install`` command now supports PKINIT for client

authenticate a host.
Also restart KRB5 KDC during ``ipa-certupdate`` so KDC picks up new CA
certificates for PKINIT.
*Requirements*
- The KDC must trust the CA chain of the client certificate.
- The client must be able to verify the KDC's PKINIT cert.
- The host entry must exist. This limitation may be removed in the
future.
- A certmap rule must match the host certificate and map it to a single
host entry.

If there are multiple servers it is possible that the client

is faster than replication then the client may not exist
on all servers and therefore enrollment will fail.
This was seen in performance testing of how many simultaneous

Setting dns_lookup_kdc to False would result in a hardcoded

For instance, adding a trust to an Active Directory forest
after clients are enrolled would result in clients not being
able to authenticate AD users. Recycling FreeIPA servers
could prove problematic if the original hostnames are not

Always set dns_lookup_kdc to True on client enrollment.

FreeIPA's Python and C code used different approaches to get the FQDN of
the host. Some places assumed that gethostname() returns a FQDN. Other
code paths used glibc's resolver to resolve the current node name to a
FQDN.
Python code now uses the ipalib.constants.FQDN where a fully qualified
domain name is expected. The variable is initialized only once and avoids
potential DNS lookups.
C code uses a new helper function ipa_gethostfqdn() in util package. The
function implements similar logic as gethostfqdn() except it uses more
modern getaddrinfo(). The result is cached as well.
