find_subscr_buffer() called indefinitely on Samsung Galaxy Nexus #52

Closed rom1v closed 11 years ago

rom1v commented 11 years ago

While I don't have this problem on other phones, on Samsung Galaxy Nexus, find_subscr_buffer() is called very very often (~10 times per second). Do you have an idea of the source cause ?

Then, it causes a lot of "Dropped frames" due to expiry timeout in overlay_stuff_packet.

So this phone can hear the packets of other devices. But it needs to request a copy of their full SID, but the request is never arriving. Is the screen off on those other devices? This often installs a packet filter that drops all incoming broadcast packets. Have you tried turning your devices on in a different order? This can affect whether or not an adhoc network forms correctly.

Is the screen off on those other devices?

No, all of them have their screen ON.

Have you tried turning your devices on in a different order? This can affect whether or not an adhoc network forms correctly.

Yes, but anyway, it happens even in WiFi client mode.

lakeman commented 11 years ago

Unfortunately, this isn't very surprising, nor is there much we can do about it except give up and start ignoring peers who can't hear us. You might have better luck getting these devices to talk to each other if this phone is turned into a hotspot that the others connect to.

rom1v commented 11 years ago

I also have problems with other phones. I have 2 Motorola Milestone and 3 HTC One S.

Motorola Milestone discover each other very quickly (1 or 2 seconds). HTC One S often fail to discover each other on ad-hoc mode. However, they do discover each other on client mode, very quickly.

Sometimes, one HTC discovers a Motorola Milestone on ad-hoc mode, but it takes time.

I have no find_subscr_buffer() in logs.

Do you think the problem is similar ? Can I do something about it ?

rom1v commented 11 years ago

After some investigations, I think it is a very low level issue.

Even a simple telnet between 2 HTC One does not work (No route to host), while it works with Motorola Milestone.

rom1v commented 11 years ago

I close this issue, since it works with modified Android IBSS (and now current Cyanogen).
