a24cd01304 ipautil: check for open ports on all resolved IPs
When a hostname is provided to host_port_open, it should check if
ports are open for ALL IPs that are resolved from the hostname, instead
of checking whether the port is reachable on at least one of the IPs.

1e6a204b43 Set explicit confdir option for global contexts
Some API contexts are used to modify global state (e.g. files in /etc
and /var). These contexts do not support confdir overrides. Initialize
the API with an explicit confdir argument to paths.ETC_IPA.

The special contexts are:

* backup
* cli_installer
* installer
* ipctl
* renew
* restore
* server
* updates

The patch also corrects the context of the ipa-httpd-kdcproxy script to
'server'.

af0ba66188 ipa-replica-conncheck: do not close listening ports until required
Previously, a separate thread would be created for each socket used
for conncheck. It would also time out after one second, after which it
would be closed and reopened again. This caused random failures of
conncheck.

Now all sockets are handled in a single thread and once the server
starts to listen on a port, it does not close that connection until the
script finishes.

Only IPv6 socket is used for simplicity, since it can handle both IPv6
and IPv4 connections. This requires IPv6 kernel support, which is
required by other parts of IPA anyway.

4a7345e448 Always qualify requests for admin in ipa-replica-conncheck
ipa-replica-conncheck connects to the master using an SSH command:
ssh -o StrictHostKeychecking=no -o UserKnownHostsFile=<tmpfile> \
    -o GSSAPIAuthentication=yes <principal>@<master hostname> \
    echo OK

The issue is that the principal name is not fully qualified (for instance
'admin' is used, even if ipa-replica-conncheck was called with
--principal admin@EXAMPLE.COM).
When the FreeIPA server is running with a /etc/sssd/sssd.conf containing
    [sssd]
    default_domain_suffix = ad.domain.com
this leads to the SSH connection failure because admin is not defined in
the default domain.

The fix uses the fully qualified principal name, and calls ssh with
ssh -o StrictHostKeychecking=no -o UserKnownHostsFile=<tmpfile> \
    -o GSSAPIAuthentication=yes -o User=<principal> \
    <master hostname> echo OK
to avoid syntax issues with admin@DOMAIN@master

The stdout and stderr of all commands are logged (unless skip_output is given).

This is because in Python 3, the output needs to be decoded, and that can
fail if it's not decodable (human-readable) text.

The raw (bytes) output is always available from the result object,
as is "leniently" decoded output suitable for logging.

7ad9f5d3d5 Prefer TCP connections to UDP in krb5 clients
In general, TCP is a better fit for FreeIPA due to large packet sizes.

However, there is also a specific need for TCP when using OTP. If a UDP
packet is delivered to the server and the server takes longer to process
it than the client timeout (likely), the OTP value will be resent.
Unfortunately, this will cause failures or even lockouts. Switching to
TCP avoids this problem altogether.

4879c68d68 Improve address family handling in sockets
Many functions use low-level socket interface for connection or
various checks. However, most of the time we don't respect
automatic address family detection but rather try to force our
values. This may cause either redundat connection tries when an
address family is disabled on system tries or even crashes
when socket exceptions are not properly caught.

Instead of forcing address families to socket, rather use
getaddrinfo interface to automatically retrieve a list of all
relevant address families and other connection settings when
connecting to remote/local machine or binding to a local port.
Now, we will also fill correctly all connection parameters like
flowinfo and scopeid for IPv6 connections which will for example
prevent issues with scoped IPv6 addresses.

bind_port_responder function was changed to at first try to bind
to IPv6 wildcard address before IPv4 as IPv6 socket is able to
accept both IPv4 and IPv6 connections (unlike IPv4 socket).

nsslib connection was refactored to use nss.io.AddrInfo class to
get all the available connections. Socket is now not created by
default in NSSConnection class initializer, but rather when the
actual connection is being made, becase we do not an address family
where connection is successful.

159e848d85 Tolerate UDP port failures in conncheck

UDP protocol is unrealiable by its nature and the port can also not

ipa-ca-install and the replica services are thus already running.

ports is printed for user.
