Subject: [PATCH] sss: use BN_set_word(x, 0) instead of BN_zero()
Different OpenSSL versions define BN_zero() differently -- sometimes
returning an integer, sometimes as void --, so let's use instead
BN_set_word() instead, not to have issues when building with these
different versions.

From d3010c89a8f516a0c9695a939a8cccca0918da2b Mon Sep 17 00:00:00 2001

Subject: [PATCH 2/2] systemd: account for unlocking failures in
clevis-luks-askpass (#343)
As unlock may fail for some reason, e.g. the network is not up yet,
one way cause problems would be to add extra `rd.luks.uuid' params
to the cmdline, which would then cause such devices to be unlocked
in early boot. If the unlocking fail, those devices might not be
accounted for in the clevis_devices_to_unlock() check, as it is
based on crypttab.
Let's make sure there are no pending ask.* sockets waiting to be
answered, before exiting.

Subject: [PATCH 4/4] luks: explicitly specify pbkdf iterations to cryptsetup
This fixes an Out of memory error when the system has not much memory,
such as a VM configured with 2GB currently being installed through the
network (hence having ~1GB free memory only).
See RHBZ #1979256 (https://bugzilla.redhat.com/show_bug.cgi?id=1979256).

Subject: [PATCH] luks: enable debugging in clevis scripts when rd.debug is set
(#340)
On Fedora/RHEL, the rd.debug kernel command line parameter controls
debugging.
By implementing the functionality inside clevis, troubleshooting will be
greatly eased.
See RHBZ #1980742 (https://bugzilla.redhat.com/show_bug.cgi?id=1980742).
