Hedy-1-0-2-dev: change uplink to tunnel-berlin (openvpn) does not work. #637

Closed pmelange closed 5 years ago

pmelange commented 5 years ago

This is tested with build b76e14d

When starting with either default or tunnel-berlin-tunneldigger, and performing an update to tunnel-berlin (openvpn) the following occurs:

This may be related to #636

pmelange commented 5 years ago

Note: switching between default and tunnel-berlin-tunneldigger and visa-versa works

pmelange commented 5 years ago

When manually running the openvpn configuration file, the following happens:

/rom/etc/uci-defaults# sh ./freifunk-berlin-z90_openvpn 
uci: I/O error
uci: Entry not found
uci: Entry not found
uci: Entry not found

as it seems to be related to https://github.com/freifunk-berlin/firmware/issues/636, have you retested this this issue also? Probably it's also gone ...

I tested it again today with b76e14d. It still is an issue. The contents of /etc/config/openvpn are wrong. I am building with commits 3db977714bc7870e777c4b15cf974ddc9242f5d4 and d4b765df0c22197df5facbfea76833724462e43d. When I have tested, I will post

@SvenRoederer I think I found the problem. The function guard has an exit in it. Maybe it should just return.

EDIT: I think that this is more the problem https://github.com/freifunk-berlin/firmware-packages/commit/f1d7277853db25c7657ffa455b54c933669483a3

I think I found the problem. The script /rom/etc/uci-defaults/freifunk-berlin-z90_openvpn is not executable. We need to call it with sh. sh /rom/etc/uci-defaults/freifunk-berlin-z90_openvpn

I have added commit https://github.com/freifunk-berlin/firmware-packages/commit/f1d7277853db25c7657ffa455b54c933669483a3 to a new branch. It addresses the call to /rom/etc/uci-defaults/freifunk-berlin-z90_openvpn. I am building locally and will report after I've tested.

@SvenRoederer I have finished testing. The changes in https://github.com/freifunk-berlin/firmware-packages/commit/f1d7277853db25c7657ffa455b54c933669483a3 are important but doesn't solve the issue.

When uci commit is run in the script, there is an error: uci: I/O error I tried to remove the file

# rm /etc/config/openvpn
rm: can't remove '/etc/config/openvpn': Stale file handle

If I edit the file manually, it works. After, if I try to do rm again, I get the same "Stale file handle" error.

Do you have any ideas?

SvenRoederer commented 5 years ago

with https://github.com/freifunk-berlin/firmware-packages/commit/6da0d4e755942aeaf57622a15c1cf554d61541f6 we have a way to work around this problem. I'm ok with this solution for hedy-1.0.2. For v1.1.x we should think of a clean solution.

let's close this here.

pmelange commented 5 years ago

Yes, let's close this issue and continue the discussion in #641
