DHCP leases file not getting updated

[spowelljr]

We've been getting issues on our personal machines where our DHCP leases file is not being updated after starting an instance with socket_vmnet. The fix so far has been uninstall socket_vmnet, reboot machine, reinstall, which resolves the issue. However I'm trying to integrate GitHub Action tests for QEMU/socket_vmnet and I'm getting the same thing (logs below).

Is there a command we could run that would resolve this issue? I see in the README there's a command to Reload the DHCP daemon

sudo /bin/launchctl kickstart -kp system/com.apple.bootpd

I'm not sure if that should resolve the issue, however trying to run it in GitHub Action resulted in Could not find service "com.apple.bootpd" in domain for system

Below are to logs from the GitHub Action machine with the main error being StartHost failed, but will try again: creating host: create: creating: IP address never found in dhcp leases file: failed to get IP address: open /var/db/dhcpd_leases: no such file or directory

We experienced the same thing on our personal machines, we tried manually creating the file just incase the there were some permission errors but that didn't resolve the issue, plus I'm sure it's more than capable of creating the file itself.

Any help would be appreciated, thanks!

any idea @AkihiroSuda what might cause this? we see this error as a Flake on our mac Os sometimes, but on Github Action it happens all the time. so I think finding the root cause would help a lot of users

[AkihiroSuda]

Could you make sure that you are NOT using the bridged mode?

Github Action

Bridged mode is known not to work on Github Action

[spowelljr]

I'm just running

sudo make PREFIX=/opt/socket_vmnet install

Which according to the comments in the Makefile Empty value (default) disables bridged mode. bridged mode is not being used.

@AkihiroSuda are there any debugging commands you suggest I could run to get you more logs? I currently have the problem on Mac M1 with minikube here are the logs if it helps with debugging (the log is too long I attach here) lastStart.txt

but here is the last part of the log

[spowelljr]

When an instance is terminated it logs the following:

$ cat /var/run/socket_vmnet.stderr
on_accept(): vmnet_return_t VMNET_INVALID_ARGUMENT
vmnet_write: Undefined error: 0

Not sure if that's expected or not.

[spowelljr]

@AkihiroSuda Is there anything I could do (debug commands, etc.) to help figure out this issue? I'm still experiencing this issue.

[AkihiroSuda]

Cc @jandubois could you take a look?

[spowelljr]

I just uninstalled, rebooted, and installed with master and it works now, not sure if recent commits fixed this

[mprimeaux]

@spowelljr I assume you built from source? I ask because there is a brew formula for socket_vmnet as well.

[spowelljr]

Correct, from source

[mprimeaux]

Thanks. Would be good to know if it still works after surviving a reboot. Regardless, I'll perform the exact steps you did and update everyone.

[mprimeaux]

TLDR; DHCP address allocation works when not in bridged mode and directly building socket_vmnet from the latest sources. Bridged mode fails.

When compiling for bridged mode with...

sudo make PREFIX=/opt/socket_vmnet install BRIDGED=en0

...and then starting minikube with....

minikube start \
  --network socket_vmnet \
  --socket-vmnet-client-path="/opt/socket_vmnet/bin/socket_vmnet_client" \
  --socket-vmnet-path="/var/run/socket_vmnet.bridged.en0"

...results in the following failure:

😿  Failed to start qemu2 VM. Running "minikube delete" may fix it: creating host: create: creating: IP address never found in dhcp leases file: failed to get IP address: could not find an IP address for 76:b3:20:a2:9b:74

❌  Exiting due to GUEST_PROVISION: Failed to start host: creating host: create: creating: IP address never found in dhcp leases file: failed to get IP address: could not find an IP address for 76:b3:20:a2:9b:74

Of course minikube delete does not 'fix it'.

What's interesting is I can confirm a new DHCP address is being allocated since my firewall notifies me of new device activity. However, I don't see any new addresses in /var/db/dhcp_leases. I can also confirm the MAC address of the newly allocated DHCP address lease matches the MAC address in the above error.

I've also followed this "Known Issues" workaround to no avail.

UPDATE: As another interesting data point, I am able to start Lima using the same socket_vmnet in bridged mode without any issue using the following excerpt from limactl start --name=default template://vmnet.

network:
  - lima: bridged

[jandubois]

However, I don't see any new addresses in /var/db/dhcp_leases.

That is expected, as bridged IP addresses are assigned by the DHCP on your local network, and are not local to your host. That is the whole point of using a bridged network: to get an externally routable IP address, so other machines can connect to your VM.

Maybe this helps:

socket_vmnet works basically the same, except there is no vde_switch involved.

[mprimeaux]

@jandubois Yes. That helps quite a bit. Thanks!

[mprimeaux]

@jandubois I've attached the logs.txt from my latest attempt with bridged mode.

Given the logs are Minikube, if folks prefer, I can move this over to the linked Minikube issue 15300.

[jandubois]

@mprimeaux I'm not sure what you are trying to achieve. You will not be able to get the IP address of the bridged network from the host machine. You will have to run e.g. ip a show lima0 (replace with iface name of your bridged network) inside the VM.

It looks like minikube only supports looking in the local leases log, so it does not support bridged networks at the moment. Somebody will have to add it. If you don't have a slirp interface to use in addition to the bridged network, then you will have to add something to the VM setup to log the address in a place that can be inspected externally.

I tried to see if there is a way to determine the address via arp -a, but it seems complicated. The address is not present initially, so I tried running ping 192.168.255.255 (because my local net is 192.168/16), but even after running it for a minute, I don't get a ping response from my VM. I have to ping it directly, but even looping over just a /24 network and pinging each address takes considerable time.

There is probably a way to force the VM to announce itself, e.g. by incorrectly broadcasting that the MAC address belongs to the host, but then giving up when the VM replies "well, actually, that is my MAC address". But that feels rather hacky (and I haven't tried if it actually works, as the bridged interface technically does belong to the host).

In all, querying the IP address via a local slirp connection seems to be the way to do this.

[jandubois]

I can move this over to the linked Minikube issue 15300.

I think this is just missing functionality in minikube and don't see what could be done in the socket_vmnet repo to improve the situation, so the discussion should probably more there.

[mprimeaux]

@jandubois In short, what I'm trying to accomplish is to have the Kubernetes control plane (minikube) obtain a routable address on my host network.

[medyagh]

I still have this problem, I confirm that uninstalling and rebooting and re-installing from source fixes it (but after a few days it goes bad again) so the root of the problem still exists on the code on HEAD.

@AkihiroSuda is there any reason a restart would fix this ? is there a process other than "/opt/socket_vmnet/bin/socket_vmnet" that we could check for, that maybe is not killed or stoppped after installation ? that only a restart kills it ?

or is there a "lock" on a file or something like that ? I just need to find out what exactly "restart" does that uninstalling/reinstalling without restart wont do the trick....

that way we could tell our users or make minikube just do that when it happens automatically

[mprimeaux]

@medyagh It's coincidental that you mention this as this happened to me just today. I ended up rebooting to fix. Could this be due to network going to sleep or an other power option in macOS? Just a hypothesis.

[AkihiroSuda]

My assumption is that this is an issue of Apple's bootpd (https://github.com/apple-oss-distributions/bootp) or com.apple.NetworkSharing , but not 100% sure.

If sudo /bin/launchctl kickstart -kp system/com.apple.bootpd doesn't work, sudo /bin/launchctl kickstart -kp system/com.apple.NetworkSharing may potentially work. Restarting other services (see sudo /bin/launchctl list) might be worth trying too.

[medyagh]

@AkihiroSuda I wonder if could this be related to Crop VPNs ? is there a way to add logs or detect if it is being blocked by a corp VPN?

It seems like this problem comes back after a few days of working without any issue. At first, rebooting and re-installing from the source was working but now it's not.

@medyagh FWIW, I am not and I also experience the same issue at times and, like @onatm, after a few days it fails.

I've played around with power options (e.g. don't sleep and wake on network activity) but the problem still persists.

Fortunately, I've been able to recover using various techniques ranging from a reboot to uninstalling / installing socket_vmnet.

for me I haven't recovered yet even after uninstalling/rebooting. @mprimeaux im am curious are u using this with Lima or minikube ? and are you behind a VPN or use it a corp laptop ?

[mprimeaux]

@medyagh I use socket_vmnet for both Lima and Minikube and I run them concurrently. We build our multi-arch container images on Lima and then deploy to Minikube. No corporate VPN involved as the computers aren't corporate assets.

In many cases, what works for me is (1) stop socket_vmnet, (2) uninstall socket_vmnet, (3) reboot, (4) reinstall socket_vmnet, and (5) restart socket_vmnet. All of this is a pain to say the least.

I've been playing around with running k8s in Lima since that allows me to obtain a routable address on my local network (bridged mode) as I have other IoT devices that I'm working with against the k8s cluster. That seems fine.

Also, as another data point, Lima locks up frequently when building our multi-arch container images; but only on macOS ARM64. macOS Intel is stable. The only way to recover is to force a stop limactl stop --force and then rebuild the VM. Again, less than ideal. I haven't had time to reason through hypotheses to either prove or disprove them in search of root cause.

Let me know if I can provide any other details. Just trying to get back above water so I can reconvene on testing various issues and configurations across socket_vmnet, minikube, and lima.

[mprimeaux]

...and thanks for Lima v0.15.0, its much easier to start k8s in Lima with bridged networking enabled.

limactl start --set='.cpus = 4 | .memory = "16GiB" | .networks[0] = { "socket": "/opt/homebrew/var/run/socket_vmnet.bridged.en0"}' template://k8s

Possible before but I had to download the k8s template locally and modify it. This shortens my debug cycles with various configurations.

[ShockleyJE]

Adding confirmation that +1 is experiencing the issue on Ventura 13.0 M1 Max with latest minikube, qemu, and socket_vmnet.

Minikube is fine with only qemu until needing to expose external IP's to test services with external IP's.

I installed socket_vmnet & started the service like such:

brew install socket_vmnet
brew tap homebrew/services
HOMEBREW=$(which brew) && sudo ${HOMEBREW} services start socket_vmnet

I should also note that I was on an ethernet connection & no corp proxy.

If there's anything I can do to help with troubleshooting for y'all please feel free to request.

[jandubois]

Adding confirmation that +1 is experiencing the issue

I'm not sure what "the issue" is in this discussion anymore. As I explained above, the DHCP lease information will never be found on the local machine because it comes from the local network and not the builtin DHCP. You have to determine that IP address from inside the VM, e.g. by also having a shared or host-only interface, whose IP address you can get from the local leases file.

I don't think there is anything left to discuss about that.

If this discussion is about socket_vmnet hanging, then I think there should be a separate Github issue for that, and this issue should be closed.

[mprimeaux]

@jandubois I agree that a different issue should be opened. Sorry for the tangent.

Speaking for my desire (to have Minikube + QEMU driver work in bridged mode), a minikube enhancement request might be the best course of action.

@jandubois are you saying even at the times that socket_vmnet with minikube works well with minikube, even at those times the DHCP were not found in minikube either ? I dont think thats has been the case in my experience. when it works, minikube finds the lease on before the 6th try ... but when it doesnt work it wont find it and times out

[jandubois]

I'm sorry, I was only thinking about /var/db/dhcpd_leases in my previous answers, and that file cannot contain entries for bridged network adapters (see the image at the top of the thread). It (dhcpd) only records the leases it has issued itself, not the ones that have been received.

But I just realized that macOS also stores client leases under /var/db/dhcpclient/leases, and it would make sense if it also recorded the leases it has requested for bridged vmnet networks in there. Alas on the machines I just checked this doesn't seem to be the case; I only see leases for host adapters.

[afbjorklund]

In all, querying the IP address via a local slirp connection seems to be the way to do this.

This is the traditional (i.e. VirtualBox) approach, later copied to other drivers such as libvirt

[aelsnz]

Question here and maybe this is not related, but based on tests I have been running I think this might be - and indicating a change or issue with bootp and the allocation of DHCP addresses to the bridge network.

See - https://github.com/lima-vm/lima/issues/1259

The issue I have seen is that on Mac OS 13.3 M1 is that when I try to use Colima / Lima / Minikube with sock_vmnet and qemu is that the DHCP address is not being allocated.

If I stop bootp, and add basic DHCP server with isc-dhcp I can see that DHCP addresses are being requested via the sock_vmnet/bridge into the VMs.

Now with Minikube it seem to look for specific format of the dhcpd_leases and it must be /var/db/dhcpd_leases so I still get failure on starting minikube but I think this now only due to the format of the leases file being different than expected.

btw this does not on github action, do you have any clue/guess how github action MacOs could be different ?

This issue is solved on physical macbooks, but still persists on github action macos

I suggest we rename this issue, and it might be helpful to investigate with Github Action Environments to see if they know if any special quirks of gh action envs ?

Unfortunately, even with sudo, we cannot run the above workaround commands on Macs enrolled in Mobile Device Management (MDM)

$ sudo /usr/libexec/ApplicationFirewall/socketfilterfw --add /usr/libexec/bootpd
Password:
Firewall settings cannot be modified from command line on managed Mac computers.

I imagine this would be a common occurrence for developers working for a medium-large company and where difficult to persuade their company's IT department to allow firewall exceptions, though based on my limited knowledges seems doable - https://developer.apple.com/documentation/devicemanagement/firewall/applicationsitem

Is it possible this is actually a bug on Apple's end and if so has anyone reported it https://developer.apple.com/bug-reporting/? We only see this bug only after rebooting where socket_vmnet was enabled on some previous boot via sudo brew services start. Apple's documentation themselves seem to indicate that DHCP shouldn't be blocked (and in instances where we start the service from fresh install isn't)

From https://developer.apple.com/documentation/vmnet#1681413

The interface receives a private IPv4 address via DHCP

I have verified using wireshark that QEMU VM starts/boots and sends through a DHCP Discover request packets (broadcast) port 67 on the vmenet0 and bridge100 interfaces created by socket_vmnet. launchd is listening on UDP port 67 on all interfaces

$ sudo lsof -iUDP:67 -P
Password:
COMMAND PID USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
launchd   1 root   24u  IPv4 0x2727b31c239489bb      0t0  UDP *:67
launchd   1 root   25u  IPv4 0x2727b31c239489bb      0t0  UDP *:67

Presumably launchd is just not socket activating /System/Library/LaunchDaemons/bootps.plist to fulfil the DHCP request.

@tmoschou - unfortunately I think the firewall MDM profile attributes only allows specifying apps via a BundleID and I don't think /usr/libexec/bootpd has a BundleID.

Microsoft InTune docs for creating macOS details a way to get the BundleID of an app but it returns an empty value for bootpd:

~ osascript -e 'id of app "/usr/libexec/bootpd"'

Compared to other things:

~ osascript -e 'id of app "Notes"'
com.apple.Notes

~ osascript -e 'id of app "/usr/libexec/not_a_real_thing"'
0:2: execution error: Can’t get application "/usr/libexec/not_a_real_thing". (-1728)

[tmoschou]

I don't think /usr/libexec/bootpd has a BundleID

Ah maybe com.apple.bootpd might work? Its the Label value used in /System/Library/LaunchDaemons/bootps.plist

[avoidik]

in my case I do not have bootpd entry on the Firewall list UI, but if I decode the com.apple.alf.plist I can see it there anyway

    <key>exceptions</key>
    <array>
        <dict>
            <key>path</key>
            <string>/usr/libexec/bootpd</string>
            <key>state</key>
            <integer>3</integer>
        </dict>
        ...
    </array>

I assume there's no need to enlist it, it would be great if someone could confirm this
