zerotier-cli leave command timing out on Linux 5.10.60-qnap

[iranee]

Hello,

I'm experiencing an issue with the zerotier-cli leave command on my system running Linux version 5.10.60-qnap. I've compiled ZeroTier statically and it runs fine, but when attempting to leave an existing network ID, it hangs and eventually times out. Using the official Docker image, I created a chroot environment locally with the correct library versions, and I can run zerotier-one, join networks, but face the same issue when trying to leave an existing network ID—it hangs for nearly a minute before displaying "0 leave timed out". At this point, running zerotier-cli listnetworks also hangs until I terminate the zerotier-one process.

I have already run modprobe tun and confirmed its presence.

Here are the details:

• Expected Behavior: The zerotier-cli leave command should successfully leave the network without hanging or timing out.

• Actual Behavior: The command hangs and times out when attempting to leave an existing network ID.

• Reproduction Steps:

  1. Join a network using zerotier-cli join <networkID>.
  2. Attempt to leave the network using zerotier-cli leave <networkID>.
  3. Observe the command hanging and eventually timing out.

• Console Output: "0 leave timed out" when attempting to leave a network.

• System Information:
  Linux version 5.10.60-qnap (root@debian) (x86_64-QNAP-linux-gnu-gcc (toolchain config: [gcc-4.9.2 binutils-2.25 glibc-2.21]) 4.9.2, GNU ld (GNU Binutils) 2.25) SMP Fri Aug 5 09:29:04 CST 2022

• ZeroTier Version: I am using the latest release of ZeroTier v1.14.2.

• No problems were encountered with version 1.12.2.

Any assistance with this issue would be greatly appreciated.

Thank you!
