WNDR3700v1 pppoe (pppox.ko) fails to load on boot (extroot)

[redcow]

I'm using as router the netgear WNDR3700v1 with openwrt trunk r26583. I use extroot which works fine, but lately probably due to changes to the extroot package? (around r26314)? I have some strange filesystem behaviour, "pppox.ko" does not load on boot hence no pppoe.

log:

dmesg:

I have to load manually the pppox.ko module, loading it with "insmod pppox.ko" fails thats probably the reason why it fails to autoload on boot.

The strange thing is as the log shows that "ls -lisa /lib/modules/2.6.37.6" and "ls -lisa /rom/lib/modules/2.6.37.6" show a different outcome eventhough, so it seems like a filesystem error, but the usb stick and the filesystem as the directory structure is just fine.

Same with a WNDR3700v2 Router here, r26801. I use only the internal memory, so no USB stick or something. Same error with pppoe.

Same problem here with arokh's build 27153 for WNDR3700v1. PPPOE worked fine after flashing but after installing the fat fs kernel module the same error as described by redcow happened. I get the same log as redcow above. The strange thing is, you can rename pppox.ko to pppox2.ko and it shows up doing an ls. Renaming it back to pppox.ko and it is (somehow) hidden again.

[arokh <trondah@…>]

I believe this is the exact same problem as I am having:

​https://forum.openwrt.org/viewtopic.php?id=30820

A file that exists on the extroot filesystem "disappears" when overlaid with /rom. You can't see it when doing an ls, but if you ls the specific filename, it's there.

[jow]

Was there kernel built with xattr support?

[arokh <trondah@…>]

Yes, default trunk kernel options. I only build in ext4 support though, perhaps it would work with the ext3 module instead?

[arokh <trondah@…>]

It didn't.

[nbd]

is this still an issue with the current 2.6.39 builds?

[arokh <trondah@…>]

I would think so, there's been no changes to the overlayfs patch as far as I know and this has been an issue for a very long time. Is anybody using extroot on ar71xx at all?

[nbd]

the 2.6.39 overlayfs patch is different from the 2.6.37 one. please try it.

[arokh <trondah@…>]

I already did, my report is from 2.6.39.3.

[nbd]

OK, I'll update overlayfs to the latest version soon

[mkisto@…]

I'm having same problem here with r28173 on a TL-MR3220. In my case, nf_conncrack.ko is disappearing.

[jogo]

please try with latest trunk, I updated overlayfs, which includes several fixes.
