I see Wireguard, can Tailscale be supported?

[thereal-BLKMGK]

Tailscale is based on Wireguard but makes setup even easier. Would adding Tailscale be possible? It's able to run on routers so hopefully the processor wouldn't be an issue.

[gtxaspec]

tailscale works, but the binaries are huge, exceeding the total capacity of the onboard flash storage chips. you can download the binaries to an sd card and run it from there.

[thereal-BLKMGK]

Oh duh, you're right it's a pig and I've been used to putting it on things with much more storage. I like your idea of using the SD card though! I've ordered up a pile of cards and will hopefully be able to poke at it tomorrow - thank you for pointing that out! I'll report back as to how it goes, hopefully as smooth as my Unifi router went :) I'll be trying a microUSB ethernet\POE thingy next!

@gtxaspec - Obviously it's still hefty, but looks like the tailscale docs claim to get the binary down to ~5mb

https://tailscale.com/kb/1207/small-tailscale

Do you know if their suggestions were used when you tested the binary in these commits, or did you just want to avoid the idea of a packer completely for all the reasons?

• add thingino-tailscale package 4eef7cf
• tailscale: drop package due to its huge size 3fdeadb

[gtxaspec]

i can add the package back into the repo compressed, but it's still too big to include enabled by default obviously. if you compile your own build, which is very easy, you'll be able to include it.

[gtxaspec]

another issue is i can't get tailscale to compile from source using the buildroot system...

[gtxaspec]

ok i figured it out. compressed, the combined binary tailscale is now 4.4mb.
thanks to @numericOverflow for the link to small tailscale.

[gtxaspec]

added back in:
cec0c1d
enable with BR2_PACKAGE_THINGINO_TAILSCALE=y

[numericOverflow]

Cool.

I'm not familiar with how this is ultimately included in the firmware. I was going to try it out but I'm not seeing it on my cam. Do I need to compile my own version, or what's needed to get the binary on the cam this way?

[gtxaspec]

yes, you need to compile your own version with that option enabled.

I got this working with a patch to the package defs:

-define TAILSCALE_LINUX_CONFIG_FIXUPS
-	$(call KCONFIG_ENABLE_OPT,CONFIG_TUN)
+define THINGINO_TAILSCALE_LINUX_CONFIG_FIXUPS
+	$(call KCONFIG_SET_OPT,CONFIG_TUN,m)

Think there was a typo.

However, tailscaled keeps getting killed due to OOM. I worked around this with a custom launcher that would respawn on non-zero exit, but seems pretty spotty, so I went back to vanilla wireguard.

Is there a way to reduce memory usage? I'm running pretty much stock firmware + tailscale on a wyze cam v3.

[andypiper]

I am thoroughly confused.

No matter where I add BR2_PACKAGE_THINGINO_TAILSCALE this does not seem to add it.

I'd also like to be able to disable Telegram, since I never use that and it can save some memory.

Support was dropped

I think this is an area actively changing based on 31200af

[gtxaspec]

Tailscale is now included in buildroot natively, so this is easier now. Live in master, needs testing.

[andypiper]

happy to test, failing to find! Should be in make menuconfig under Extra Packages AFAICT, but not showing up for my Cinnado :-/

Update: I attempted to install Tailscale on the Xiaomi MJSXJ03HL using the small binary, but it fails due to insufficient RAM, resulting in an OOM (Out of Memory) error. The failure appears to occur during decompression, as even the small binary requires more memory than the device can provide.

I also tried placing the small binary on the SD card, but the same OOM error occurs. Next, I tested running the already uncompressed binary directly from the SD card, which also led to a dead end.

Additionally, I later confirmed that the firmware does not support TUN/TAP. Without TUN support, there is no viable way to integrate or run Tailscale on this device at the firmware level.

[gtxaspec]

The firmware needs to be compiled with the tailscale binary, this should enable tun/tap support (check the kernel configs in the repo)
I would also not recommend running it on devices with only 64mb of ram, 128mb only.
