That message likely contains less than 1 kiB of ASCII text, and isn?t held in RAM continuously anyway. That

Hello. I'm a distro maintainer and was wondering about the efficacy of entropy daemons like haveged and jitterentropyd in qemu-kvm. One of the authors of haveged [0] pointed out if the hardware cycles counter is emulated and deterministic, and thus predictible. He therefore does not recommend using HAVEGE on those systems. Is this the case with KVM's counters? PS. I will be setting VM CPU

Hi, I maintain Kodi[1] in RPMFusion[2] and the latest version of Kodi, 18.0, is crashing when trying to browse the SMB network. The previous version, 17.x, worked fine. The backtrace shows that Samba was not able to open /dev/urandom, which can't be true and must be masking another issue. The issue occurs on any Fedora 28 or 29 system (multiple user reports[3]). SELinux is disabled and

Hello, I didn't find a mailing list for rng-tools, so CC'ing the kernel lists and the last few committers. The first patch in this series adds a udev rule to start rngd for guests that have a virtio-rng device available. The second patch attempts to add autoconf magic to install the udev rule in the system dirs. However, installing as non-root will obviously fail. Prefixes are also

Hi, I've discovered an issue which I don't understand. On a new test install of EL9 I saw this message in the logs: Mar 01 08:09:18 <hostname> pcp-pmie[2870]: Low random number entropy available 15.6%avail at beta.corp.invoca.ch This is on a 64 core "AMD Opteron(tm) Processor 6282 SE" server but I also got the same low entropy on an EL9 KVM guest running on a "AMD

I''m looking for some help in getting the proper escape sequence within the generate function. Ultimately what I''m trying to do is generate some random strings, store them as variables, and use those variables to populate configuration files stored as templates. I can get this to work when applying the template on the localhost, but it fails when applied via the puppet
