Package: unbound Version: 1.17.1-2+deb12u2 I'm using Raspbian bookworm OS arm 64 bit. I am reporting this bug here because the package came from the Debian archives.
Linux pi 6.6.31+rpt-rpi-2712 #1 SMP PREEMPT Debian 1:6.6.31-1+rpt1 (2024-05-29) aarch64 GNU/Linux I also posted this info in the Raspberry Pi forums here: https://forums.raspberrypi.com/viewtopic.php?t=372141 Also, to the package maintainer, it would be awesome if you would include script and Systemd service files to implement what I did. I'll send you what I made if you ask me. Send me a direct message. When I run the command "unbound-control load_cache < zero_length_file" it hangs. You should be able to reproduce the bug by running that command with a zero length file as input. I put this command in a script that runs when I (re)start unbound, and sometimes the saved cache file is 0 length which causes the script to hang and eventually timeout. I found this out due to a bug in my script that makes it sometimes create a 0 length cache file when I stop unbound. I think this is probably an upstream bug. The program might not check the size of the file it is trying to read to see if it is 0 length. $ apt policy unbound unbound: Installed: 1.17.1-2+deb12u2 Candidate: 1.17.1-2+deb12u2 Version table: *** 1.17.1-2+deb12u2 500 500 http://deb.debian.org/debian-security bookworm-security/main arm64 Packages 100 /var/lib/dpkg/status 1.17.1-2+deb12u1 500 500 http://deb.debian.org/debian bookworm/main arm64 Packages Some logs from my scripts...
