Fraser Tweedale f2b1b5b07c ipa-cert-fix: improve handling of 'pki-server cert-fix' failure
'pki-server cert-fix' has a known and expected failure when the DS
certificate is expired.  'ipa-cert-fix' handles this by
optimistically ignoring the CalledProcessError and continuing when
the DS certificate was up for renewal.

This heuristic is a bit too optimistic.  If 'pki-server cert-fix'
fails due and returns nonzero due to some other, more serious error
(as has been seen in the wild[1]), 'ipa-cert-fix' continues then
fails later with a more confusing error, for example:

    [Errno 2] No such file or directory:
      '/etc/pki/pki-tomcat/certs/27-renewed.crt'

[1] https://bugzilla.redhat.com/show_bug.cgi?id=1930586

Improve the heuristic by also checking whether output files
corresponding ot all of the "extra" certificate that we asked
'ipa-cert-fix' to renew, do indeed exist and are X.509 certificates.

If the Apache, 389-ds or KDC certificate was issued by
a third party there is nothing we can do, regardless of
whether it is expired or not.

Rob Crittenden f1e12c75f1 Don't double-report any errors from pki-spawn failures
The output from pki-spawn is already displayed to the user
as well as a short traceback so re-displaying the CalledProcess
error provides no value and only provokes confusion,
particularly because it is condensed and includes embedded
newlines.

Re-raise the exception from None so that the traceback is
removed and while there is still an immense traceback from
the admintool class it is significantly shorter than before
and removes:

"During handling of the above exception, another exception occurred"

The handling is in fact expected.

This changes the user-facing installer output from:

  [1/28]: configuring certificate server instance
Failed to configure CA instance: CalledProcessError(Command ['/usr/sbin/pkispawn', '-s', 'CA', '-f', '/tmp/tmpr5x2l0gm', '--debug'] returned non-zero exit status 1: 'INFO: Connecting to LDAP server at ldap://ipa.example.test:389\nINFO: Connecting to LDAP server at ldap://ipa.example.test:389\nDEBUG: Installing Maven dependencies: False\nERROR: KeyError: \'CA\'\n  File "/usr/lib/python3.9/site-packages/pki/server/pkispawn.py", line 575, in main\n    raise KeyError(\'CA\')\n\n')

The output is similarly reduced in the installer log. There is no

Hopefully this will encourage users to focus on the logs rather than

Alexander Bokovoy c842d4b5c2 trust-fetch-domains: use custom krb5.conf overlay for all trust operations
Operations in FIPS mode make impossible use of NTLMSSP when
authenticating to trusted Active Directory domain controllers because
RC4 cipher is not allowed. Instead, Kerberos authentication have to be
used. We switched to enforce Kerberos authentication when communicating
with trusted domains' domain controllers everywhere.

Kerberos library uses system wide configuration which in IPA defaults to
resolving location of KDCs via DNS SRV records. Once trust is
established, SSSD will populate a list of closest DCs and provide them
through the KDC locator plugin. But at the time the trust is established
performing DNS SRV-based discovery of Kerberos KDCs might fail due to
multiple reasons. It might also succeed but point to a DC that doesn't
know about the account we have to use to establish trust.

One edge case is when DNS SRV record points to an unreachable DC,
whether due to a firewall or a network topology limitations. In such
case an administrator would pass --server <server> option to
'ipa trust-add' or 'ipa trust-fetch-domains' commands.

'ipa trust-fetch-domains' runs a helper via oddjobd. This helper was
already modified to support --server option and generated custom
krb5.conf overlay to pin to a specific AD DC. However, this
configuration was removed as soon as we finished talking to AD DCs.

With switch to always use Kebreros to authenticate in retrieval of the
topology information, we have to use the overlay everywhere as well.

Convert the code that generated the overlay file into a context that
generates the overlay and sets environment. Reuse it in other
trust-related places where this matters.

Oddjob helper runs as root and can write to /run/ipa for the krb5.conf
overlay.

Server side of 'ipa trust-add' code calls into ipaserver/dcerpc.py and
runs under ipaapi so can only write to /tmp.  Since it is a part of the
Apache instance, it uses private /tmp mounted on tmpfs.

ACME will not be deployed but on upgrade, if pki 10.10.x is available
then it will be.

Alexander Bokovoy 3fa07a1080 ipaserver/dcerpc.py: enforce SMB encryption on LSA pipe if available
We want to always use SMB encryption if it is possible on LSA pipe as we
are going to pass what accounts to a plain-text content within
CreateTrustedDomainEx2 call.

The catch is that older Samba version might not have a way to enforce
this and we need fall back to work with existing connection then.

Alexander Bokovoy 8ab9bf68a4 ipaserver/dcerpc.py: use Kerberos authentication for discovery
In FIPS mode we cannot rely on NTLMSSP at all, so we have ensure
Kerberos is used by Samba Python libraries. This is achieved by
requiring credentials objects to always use Kerberos authentication.

Additionally, we have to normalize the principal used to authenticate.
In case it was passed without realm, add forest root domain as a realm.
In case it was passed with NetBIOS domain name, remove it and replace
with a realm. Since we only know about the forest root domain as a
realm, require that for other domains' users a real Kerberos principal
is specified.

Alexander Bokovoy 753246f4e8 ipaserver/dcerpc: use Samba-provided trust helper to establish trust
When establishing trust to Active Directory forest, RC4 is used to
encrypt trusted domain object credentials as an application-specific
material in a secure channel based on AES session key.

In FIPS mode it is not possible to use RC4 directly.

Samba 4.14 and backports to 4.13 in Fedora 33+ and RHEL 8.4+ now
provide a helper that wraps LSA RPC call CreateTrustedDomainEx2.
This helper ensures that in FIPS mode we first check that LSA session
key is AES before allowing RC4 use internally in Samba bindings. Thus,
it becomes possible to establish trust to Active Directory forest in
FIPS mode.

Adopt FreeIPA code to use the helper provided by Samba when it is
available. If neither the helper nor unprotected arcfour_encrypt utility
is available from Samba bindings, fail import of the ipaserver.dcerpc
module.

Alexander Bokovoy eca22818c9 odsexporterinstance: use late binding for UID/GID resolution
Move actual resolution of UID/GID values for 'ods' entities to the code

up without DNS feature. In particular, 'ods' user and group are created
when 'opendnssec' package is installed and if 'opendnssec' package is
not installed, uninstall fails in OpenDNSSEC Exporter instance
constructor.

We use common pattern of checking the service during uninstall:

 svc = SVCClass()
 if svc.is_configured():
    svc.uninstall()

Thus, service class constructor must not do UID/GID resolution

Florence Blanc-Renaud cf30cc3f63 Improve PKI subsystem detection
The dogtaginstance.is_installed() method currently relies on
the presence of the directory /var/lib/pki/pki-tomcat/{ca|kra},
even if it is empty.
An unwanted consequence is ipa-server-upgrade wrongly assuming the KRA
is installed and crashing when trying to upgrade a not-installed
component.

The fix relies on the command "pki-server subsystem-show {ca|kra}" to
detect if a subsystem is installed. The command does not require PKI
to be running (hence can be called anytime) and is delivered by
the pki-server package which is already required by ipa server pkg.

Alexander Bokovoy 184997e85d systemd: enforce en_US.UTF-8 locale in systemd units
Python code does detection of the system encoding based on the locale
settings. On RHEL 8.4 development images we somehow get LANG=en_US which
defaults to iso8859-1 _inside_ the systemd-started service, even though
the whole environment defaults to LANG=en_US.UTF-8.

When instrumented with ExecStartPre=/usr/bin/locale, the following
output can be seen:

locale[45481]: LANG=en_US
locale[45481]: LC_CTYPE="en_US"
locale[45481]: LC_NUMERIC="en_US"

Set the environment to explicit LC_ALL=C.UTF-8 to please the Python
code. FreeIPA server side only cares about actual encoding, not the
language itself. We already use LC_ALL=C.UTF-8 in httpd service snippet.

Rob Crittenden 20055ddaf1 Move where the restore state is marked during IPA server upgrade
There is still some exposure to killing in a bad place. This was
reproduced by killing the process in the parser.parse() call within
__restore_config (line 230) so the values were restored from the
backup but the new dse.ldif never written or copied. But the values
had already been restored from the state file.

I'm not sure this can ever be 100% bullet-proof since it can be
externally killed but if rather than calling restore_state() on the
values in __restore_config we use get_state() which will peek at the
values in the state file without removing them. Then the last step
is to pop upgrade-in-progress and then the rest.

If the values have been restored and the new ldif written and copied
then it's only upgrade-in-progress that really matters. The rest will
be overwritten.

Rob Crittenden ea67962d5d Reorder when ACME is enabled to fix failure on upgrade
On upgrading a server without ACME to one with ACME
the RA Agent DN needs to be added as a member of the
ACME Enterprise Users group. This was previously
done as part of the creation of that entry.

So on upgrade the RA Agent wouldn't be a member so
ipa-acme-manage didn't have access to operate against
the CA REST API.

In order to add the RA Agent to this group during installation
the ACME provisioning has to come after that step so it is
moved from the middle of an installation to the end and
the group addition moved into the setup_acme() method.
