The ndr_pull_get_switch() function was dropped, but it was just a wrapper
around the ndr_token_peek() function, so we can use this approach on both
old and new versions of libndr.

From 580d61884b6c0a81357d8f9fa69fe69d1f017185 Mon Sep 17 00:00:00 2001

Subject: [PATCH] ldap_child: do not try PKINIT
if the PKINIT plugin is installed and pkinit_identities is set in
/etc/krb5.conf libkrb5 will try to do PKINIT although ldap_child only
wants to authenticate with a keytab. As a result ldap_child might try to
access a Smartcard which is either not allowed at all or might cause
unexpected delays.
To avoid this the current patch sets pkinit_identities for LDAP child
explicitly to make the PKINIT plugin fail because if installed libkrb5
will always use it.
It turned out the setting pre-authentication options requires some
internal flags to be set and krb5_get_init_creds_opt_alloc() must be
used to initialize the options struct.

Subject: [PATCH] util/watchdog: fixed watchdog implementation
In case watchdog detected locked process and this process was parent
process it just sent SIGTERM to the whole group of processes, including
itself.
This handling was wrong: generic `server_setup()` installs custom
libtevent handler for SIGTERM signal so this signal is only processed
in the context of tevent mainloop. But if tevent mainloop is stuck
(exactly the case that triggers WD) then event is not processed
and this made watchdog useless.
`watchdog_handler()` and `watchdog_detect_timeshift()` were amended to do
unconditional `_exit()` after optionally sending a signal to the group.

Subject: [PATCH 8/9] data_provider_be: got rid of duplicating SIGTERM handler
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
It was wrong to install two libtevent SIGTERM handlers both of which did
orderly_shutdown()->exit(). Naturally only one of the handlers was executed
(as process was terminated with exit()) and libtevent docs doesn't say
anything about order of execution. But chances are, be_process_finalize()
was executed first so default_quit() was not executed and main_ctx was not
freed.
Moreover there is just no reason to have separate be_process_finalize()
at all: default server handler default_quit() frees main_ctx. And be_ctx
is linked to main_ctx so will be freed by default handler as well.

Subject: [PATCH] util/sss_ptr_hash: fixed double free in
sss_ptr_hash_delete_cb()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Calling data->callback(value->ptr) in sss_ptr_hash_delete_cb() could lead
to freeing of value->ptr and thus to destruction of value->spy that is
attached to value->ptr.
In turn sss_ptr_hash_spy_destructor() calls sss_ptr_hash_delete() ->
hash_delete() -> sss_ptr_hash_delete_cb() again and in this recursive
execution hash entry was actually deleted and value was freed.
When stack was unwound back to "first" sss_ptr_hash_delete_cb() it tried
to free value again => double free.
To prevent this bug value and hence spy are now freed before execution of
data->callback(value->ptr).

From bd201746f8cf0e95615b3e98868555451b5e66b8 Mon Sep 17 00:00:00 2001

Subject: [PATCH] sdap: Add randomness to ldap connection timeout
In case of mass deployment, mass registration of IPA clients roughly on
the same time leads to regular CPU load spikes on IPA servers, the load
spikes are caused by all/most clients refreshing their LDAP connections
(ldap_connection_expire_timeout) every 15 minutes.
This patch introduces new random value (from 0 up to
ldap_connection_expire_offset) that is added to the timeout.

From 78649907b81b4bdaf8fc6a6e6ae55ed3cd5419f5 Mon Sep 17 00:00:00 2001
From: Sumit Bose <sbose@redhat.com>
Date: Fri, 27 Sep 2019 11:49:59 +0200
Subject: [PATCH 14/15] ldap: add new option ldap_sasl_maxssf
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
There is already the ldap_sasl_minssf option. To be able to control the
maximal security strength factor (ssf) e.g. when using SASL together
with TLS the option ldap_sasl_maxssf is added as well.

Subject: [PATCH 15/15] ad: set min and max ssf for ldaps
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
AD does not allow to use encryption in the TLS and SASL layer at the
same time. To be able to use ldaps this patch sets min and max ssf to 0
if ldaps should be used.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
LDAP specification allows to ommit seconds and minutes
in time border definition. In that case they defaults to zeros.
Current sssd.sudo implementation requires precision up to
seconds in time definition. This commit allows to lower
the precision up to hours.

Some implementations of C_WaitForSlotEvent() might return even if no
card was inserted. So it has to be checked if a card is really present.

Subject: [PATCH 26/26] PAM client: only require UID 0 for private socket
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Some privileged services like e.g. gdm might only call with UID 0 but
with a different GID. This patch removes the GID 0 requirement to access
to private PAM socket so that e.g. gdm can use the wait-for-card option.
