a36556e106 Allow insecure binds for migration
Commit 5be9341fba disallowed simple bind
over an insecure connection. Password logins were only allowed over LDAPS
or LDAP+STARTTLS. The restriction broke 'ipa migrate-ds' in some cases.

This commit lifts the restriction and permits insecure binds over plain
LDAP. It also makes the migrate-ds plugin use STARTTLS when a CA
certificate is configured with a plain LDAP connection.

ef39e1b02a upgrade: remove ipaCert and key from /etc/httpd/alias
With ipa 4.5+, the RA cert is stored in files in
/var/lib/ipa/ra-agent.{key|pem}. The upgrade code handles
the move from /etc/httpd/alias to the files but does not remove

instead of -D -n ipaCert which removes only the cert.

d85e0550ca ipapython.ipautil.run: allow skipping stdout/stderr logging
There are cases when output from a utility run contains sensitive
content that is better to avoid logging. For example, klist can be told
to show actual encryption keys with -K option. Redacting them out with
nolog option to ipapython.ipautil.run() is not possible because
replacement routine expects exact matches.

Introduce two boolean options that allow to skip printing output from
the utility being run:
  -- nolog_output: skip printing captured stdout
  -- nolog_error: skip printing captured stderr

These options default to False (thus, stdout/stderr content will
continue to be printed). In case they were set to True, corresponding
line will contain

   stdout=<REDACTED>

or

   stderr=<REDACTED>

64d187e56e NSSDatabase: fix get_trust_chain
In the get_trust_chain method, use certutil -O with the option
--simple-self-signed to make sure that self-signed certs properly
get processed.
Note: this option has been introduced in nss 3.38 and our spec file
already requires nss >= 3.41.

Scenario: when IPA CA is switched from self-signed to externally-signed,
then back to self-signed, the same nickname can be used in
/etc/pki/pki-tomcat/alias for the initial cert and the renewed certs. If
the original and renewed certs are present in the NSS db, running
$ certutil -O -n <IPA CA alias>
produces a complex output like the following (this command is used to find
the trust chain):
"CN=Cert Auth,O=ExtAuth" [CN=Cert Auth,O=ExtAuth]

  "caSigningCert cert-pki-ca" [CN=Certificate Authority,O=DOMAIN.COM]

    "caSigningCert cert-pki-ca" [CN=Certificate Authority,O=DOMAIN.COM]

The renewal code is disturbed by this output.
If, on the contrary, certutil -O --simple-self-signed -n <IPA CA alias> is
used to extract the trust chain, the output is as expected for a self-signed
cert:
"caSigningCert cert-pki-ca" [CN=Certificate Authority,O=DOMAIN.COM]

As a result, the scenario self-signed > externally signed > self-signed
works.

294aa3a333 Revert "Require a minimum SASL security factor of 56"
This reverts commit 3509545897.

We cannot force increase in minimum SASL security factor until our
consumers are ready to deal with it. Unfortunately, realmd uses
anonymous connection for discovery and validation of IPA LDAP server.

The way it is done is fragile (it doesn't take into account an
advertised IPA version, only checks that 'IPA' string exists in the info
field) but since bumping of minimum SSF prevents reading IPA info field
using anonymous connection, client enrollment fails.

We should get back to bumping minimum SSF after realmd and other
potential consumers are fixed.

4cd26fcba5 ipaldap: avoid invalid modlist when attribute encoding differs
ipaldap does not take into account the possibility of the attribute
encoding returned by python-ldap differing from the attribute
encoding produced by FreeIPA.  In particular this can occur with DNs
with special characters that require escaping.  For example,
python-ldap (or the underlying LDAP library) escapes special
characters using hex encoding:

  CN=Test Sub-CA 201604041620,OU=ftweedal,O=Red Hat\2C Inc.,L=Brisbane,C=AU

Whereas FreeIPA, when encoding the DN, escapes the character
directly:

  CN=Test Sub-CA 201604041620,OU=ftweedal,O=Red Hat\, Inc.,L=Brisbane,C=AU

Therefore it is possible to generate an invalid modlist. For
example, during external CA certificate renewal, if the issuer DN
includes a comma in one of the attribute values (as above), an
invalid modlist will be generated:

  [ (ldap.MOD_ADD, 'ipacaissuerdn',
      [b'CN=Test Sub-CA 201604041620,OU=ftweedal,O=Red Hat\, Inc.,L=Brisbane,C=AU'])
  , (ldap.MOD_DELETE, 'ipacaissuerdn',
      [b'CN=Test Sub-CA 201604041620,OU=ftweedal,O=Red Hat\2C Inc.,L=Brisbane,C=AU'])
  ]

Although encoded differently, these are the same value.  If this
modification is applied to the object, attributeOrValueExists (error
20) occurs.

To avoid the issue, put deletes before adds in the modlist.  If a
value is present (with different encodings) as both an addition and
a deletion, it must be because the original object contained the
value with a different encoding.  Therefore it is safe to delete it,
then add it back.

Note that the modlist is not optimal.  In the simplest case (like
above example), there should be no modification to perform.  It is
considerably more complex (and more computation) to implement this
because the raw attribute values must be decoded before comparison.

4a58adf79e Sprinkle raw strings across the code base
tox / pytest is complaining about lots and lots of invalid escape
sequences in our code base. Sprinkle raw strings or backslash escapes
across the code base to fix most occurences of:

  DeprecationWarning: invalid escape sequence

There is still one warning that keeps repeating, though:

21f14e9893 Remove Python 2 support and packages
Remove Python 2 related code and configuration from spec file, autoconf
and CI infrastructure. From now on, FreeIPA 4.8 requires at least Python
3.6. Python 2 packages like python2-ipaserver or python2-ipaclient are
no longer available. PR-CI, lint, and tox aren't testing Python 2
compatibility either.

f0228fa649 uninstall -v: remove Tracebacks
ipa-server-install --uninstall -v -U prints Traceback in its log file.
This issue happens because it calls subprocess.Popen with close_fds=True
(which closes all file descriptors in the child process)
but it is trying to use the file logger in the child process
(preexec_fn is called in the child just before the child is executed).
The fix is using the logger only in the parent process.

3ccd512dab Disable Pylint 2.0 violations
Globally disabling the following violations:

- `assignment-from-no-return` (E1111):
  Assigning to function call which doesn't return. Used when an
  assignment is done on a function call but the inferred function
  doesn't return anything.

- `keyword-arg-before-vararg` (W1113):
  Keyword argument before variable positional arguments list in the
  definition of %s function When defining a keyword argument before
  variable positional arguments, one can end up in having multiple
  values passed for the aforementioned parameter in case the method is
  called with keyword arguments.

Locally disabling the following:

- `subprocess-popen-preexec-fn` (W1509):
  Using preexec_fn keyword which may be unsafe in the presence of
  threads The preexec_fn parameter is not safe to use in the presence
  of threads in your application. The child process could deadlock
  before exec is called. If you must use it, keep it trivial! Minimize
  the number of libraries you call into.
  https://docs.python.org/3/library/subprocess.html#popen-constructor

Fixed violations:

- `bad-mcs-classmethod-argument` (C0204):
  Metaclass class method %s should have %s as first argument Used when
  a metaclass class method has a first argument named differently than
  the value specified in valid-metaclass-classmethod-first-arg option
  (default to "mcs"), recommended to easily differentiate them from
  regular instance methods.
  - Note: Actually `cls` is the default first arg for `__new__`.

- `consider-using-get` (R1715):
  Consider using dict.get for getting values from a dict if a key is
  present or a default if not Using the builtin dict.get for getting a
  value from a dictionary if a key is present or a default if not, is
  simpler and considered more idiomatic, although sometimes a bit slower

d13571942e Fix Pylint 2.0 violations
Fix the following violations aiming to support Pylint 2.0

- `unneeded-not` (C0113):
  Consider changing "not item in items" to "item not in items" used
  when a boolean expression contains an unneeded negation.

- `useless-import-alias` (C0414):
  Import alias does not rename original package Used when an import
  alias is same as original package.e.g using import numpy as numpy
  instead of import numpy as np

- `raising-format-tuple` (W0715):
  Exception arguments suggest string formatting might be intended Used
  when passing multiple arguments to an exception constructor, the
  first of them a string literal containing what appears to be
  placeholders intended for formatting

- `bad-continuation` (C0330):
  This was already included on the disable list, although with current
  version of pylint (2.0.0.dev2) violations at the end of the files
  are not being ignored.
  See: https://github.com/PyCQA/pylint/issues/2278

- `try-except-raise` (E0705):
  The except handler raises immediately Used when an except handler
  uses raise as its first or only operator. This is useless because it
  raises back the exception immediately. Remove the raise operator or
  the entire try-except-raise block!

- `consider-using-set-comprehension` (R1718):
  Consider using a set comprehension Although there is nothing
  syntactically wrong with this code, it is hard to read and can be
  simplified to a set comprehension.Also it is faster since you don't
  need to create another transient list

- `dict-keys-not-iterating` (W1655):
  dict.keys referenced when not iterating Used when dict.keys is
  referenced in a non-iterating context (returns an iterator in
  Python 3)

- `comprehension-escape` (W1662):
  Using a variable that was bound inside a comprehension Emitted when
  using a variable, that was bound in a comprehension handler, outside
  of the comprehension itself. On Python 3 these variables will be
  deleted outside of the comprehension.

f89e501ee1 Handle races in replica config
When multiple replicas are installed in parallel, two replicas may try
to create the cn=replica entry at the same time. This leads to a
conflict on one of the replicas. replica_config() and
ensure_replication_managers() now handle conflicts.

ipaldap now maps TYPE_OR_VALUE_EXISTS to DuplicateEntry(). The type or
value exists exception is raised, when an attribute value or type is
already set.
