Description of problem:
libvirt uses dnsmasq by default and I noticed failures when starting dnsmasq.
There was a missing symbol from libnettle which is added in newer version of nettle. It would be good if you could add explicit requires to minimal version of nettle.

Version-Release number of selected component (if applicable):
sh$ rpm -q nettle dnsmasq
nettle-3.3-5.fc27.x86_64
dnsmasq-2.78-6.fc27.x86_64
How reproducible:
Deterministic
Steps to Reproduce:
1. dnf install -y dnsmasq binutils
2. nm --dynamic --undefined-only /usr/sbin/dnsmasq | grep nettle_get_hashes
3. nm --dynamic --defined-only /usr/lib64/libnettle.so.6 | grep nettle_get_hashes
4. echo $?
Actual results:
sh-4.4# nm --dynamic --undefined-only /usr/sbin/dnsmasq | grep nettle_get_hashes
U nettle_get_hashes
sh-4.4# nm --dynamic --defined-only /usr/lib64/libnettle.so.6 | grep nettle_get_hashes
sh-4.4# echo $?
1
Expected results:
sh-4.4# nm --dynamic --undefined-only /usr/sbin/dnsmasq | grep nettle_get_hashes
U nettle_get_hashes
sh-4.4# nm --dynamic --defined-only /usr/lib64/libnettle.so.6 | grep nettle_get_hashes
0000000000018460 T nettle_get_hashes
Additional info:
It works well with nettle from updates-testing
sh-4.4# dnf update -e0 -d0 -y --enablerepo=updates-testing nettle
install-info: No such file or directory for /usr/share/info/nettle.info
sh-4.4# rpm -q nettle dnsmasq
nettle-3.4-1.fc27.x86_64
dnsmasq-2.78-6.fc27.x86_64
sh-4.4# nm --dynamic --undefined-only /usr/sbin/dnsmasq | grep nettle_get_hashes
U nettle_get_hashes
sh-4.4# nm --dynamic --defined-only /usr/lib64/libnettle.so.6 | grep nettle_get_hashes
0000000000018460 T nettle_get_hashes
Note: It is not required to enable updates-testing for installing nettle-3.4-1.fc27.x86_64. It is already in updates for quite a log. The issue is that Vm needn't be updated and installing dnsmasq will not update nettle due to missing requirement on new version.
I think main problem here is that nettle changes its API, but did not change its soversion. This recompilation should be with different soversion, making automatic dependencies handle this problem. Dnsmasq does not have explicit dependency on nettle, I had no place to add version. I filled bug #1549190 for it.
But since it is already broken, I will add version dependency on it. I did not realize selective updates can be broken by it.
