+Subject: [PATCH] Try to avoid OOM killer on low-memory systems without swap.
+
+Benchmark for memory-hard KDF is tricky, seems that relying
+on maximum half of physical memory is not enough.
+
+Let's allow only free physical available space if there is no swap.
+This should not cause changes on normal systems, at least.

+Subject: [PATCH] Use only half of detected free memory on systems without

+
+As tests shows, limiting used Argon2 memory to free memory on
+systems without swap is still not enough.
+Use just half of it, this should bring needed margin while
+still use Argon2.
+
+Note, for very-low memory constrained systems user should
+avoid memory-hard PBKDF (IOW manually select PBKDF2), we
+do not do this automatically.

+%package -n libcryptsetup%{so_ver}
+Summary:        Library for setting up dm-crypt Based Encrypted Block Devices
+Group:          System/Libraries
+Suggests:       libcryptsetup%{so_ver}-hmac = %{version}-%{release}
+
+%description -n libcryptsetup%{so_ver}
+cryptsetup is used to conveniently set up dm-crypt based device-mapper
+targets. It allows to set up targets to read cryptoloop compatible
+volumes as well as LUKS formatted ones. The package additionally
+includes support for automatically setting up encrypted volumes at boot
+time via the config file %{_sysconfdir}/crypttab.

+%package -n libcryptsetup%{so_ver}-hmac
+Summary:        Checksums for libcryptsetup%{so_ver}
+Group:          System/Base
+Requires:       libcryptsetup%{so_ver} = %{version}-%{release}
+
+%description -n libcryptsetup%{so_ver}-hmac
+This package contains HMAC checksums for integrity checking of libcryptsetup4,
+used for FIPS.
