Because of many reasons I have to use wvdial to manually run 3G/4G Internet connection on my laptop. It connects but strange error is dislayed:

Code: Select all: [root@piotr-l ~]# wvdial play --> WvDial: Internet dialer version 1.61 --> Initializing modem. --> Sending: ATH ATH OK --> Sending: ATE1 ATE1 OK --> Sending: AT+CGDCONT=1,"IP","internet" AT+CGDCONT=1,"IP","internet" OK --> Modem initialized. --> Sending: ATD*99# --> Waiting for carrier. ATD*99# CONNECT --> Carrier detected. Starting PPP immediately. --> Starting pppd at Tue May 28 08:58:21 2013 --> Pid of pppd: 4816 wvdial: utils/wvtask.cc:304: static int WvTaskMan::yield(int): Assertion `*current_task->stack_magic == 0x123678' failed. Aborted

The /etc/wvdial.conf file looks like:

Code: Select all: [Dialer play] Modem Type = Analog Modem Modem = /dev/ttyUSB0 Baud = 57600 Init1 = ATH Init2 = ATE1 Init3 = AT+CGDCONT=1,"IP","internet" Dial Command = ATD Phone = *99# Stupid mode = yes Username = "blank" Password = "blank" Auto DNS = no

What I am doing wrong?

You are not doing anything wrong.

I did a Google search on the error message generated by wvdial and found a relevent hit on a Fedora bug report ( https://bugzilla.redhat.com/show_bug.cgi?id=812651 ).

In the comments of the bug report here is what is stated as the problem and the solution to fix it:

Fabrice Bellet 2012-06-12 03:28:23 EDT

after bissecting the optimizations used by gcc in -O2 mode, it seems to me that the problem is caused by two specific ones : -ftree-dce and -foptimize-sibling-calls

Reverting these two options generates a library that works for me (not with wvdial, but with another application --retchmail-- that shows the same error message with the version of libwvstreams compiled with gcc-4.7.0):

$RPM_OPT_FLAGS -fPIC -fpermissive -fno-strict-aliasing -fno-tree-dce -fno-optimize-sibling-calls

Yes, thanks Fabrice!

I confirm that adding these two gcc options fixes the wvdial problem for me.
No more SIGABRTs.

I am assuming you are using Mageia 3. You should submit a bug report for it.

I am currently testing Mageia 3 KDE using the Live CD and maybe running into a related problem with Net_Applet aborting with a segfault when trying to disconnect my Mobile Broadband modem which was configured as an Analog Telephone Modem (POTS).

I got here googling the same error/crash with wvdial. So, I got the source rpm, modified the specfile with the switches in the cited bug report and built lib64wvstreams4.6-4.6.1-7.mga3.x86_64.rpm

I installed that along with the wvdial 64-bit rpm in Mageia 3 repositories. This negotiates a connection with my isp and retrieves DNS servers.

Code: Select all: $ wvdial --> WvDial: Internet dialer version 1.61 --> Cannot set information for serial port. --> Initializing modem. --> Sending: ATZ ATZ OK --> Sending: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 OK --> Modem initialized. --> Sending: ATDT2880177 --> Waiting for carrier. ATDT2880177 CONNECT 57600/V32b 14400/V42b/SREJ --> Carrier detected. Starting PPP immediately. --> Starting pppd at Sat Jun 8 14:30:06 2013 --> Pid of pppd: 1000 --> Using interface ppp0 --> pppd: Connect: ppp0 <--> /dev/ttyUSB1 --> pppd: PAP authentication succeeded --> local IP address 66.249.175.102 --> remote IP address 69.19.217.13 --> primary DNS address 207.69.188.187 --> secondary DNS address 207.69.188.186

/etc/resolv.conf has the dns servers but I get "network unreachable", ultimately. ping directly an ip doesn't work, either. I simply disconnect by `ifconfig eth0 down` or the network manager my broadband connection before trying this and there might be some interference from that, idk, I'm not very network savvy. I do get this:

Code: Select all: # route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface default * 0.0.0.0 U 0 0 0 ppp0 69.19.217.13 * 255.255.255.255 UH 0 0 0 ppp0

Maybe someone wants to try the rpm with their app on a 64-bit machine: lib64wvstreams4.6-4.6.1-7.mga3.x86_64.rpm

I just install Your rpm, but still I got wvdial error. The connection works, but the error still exist. I use 64 bit M3 too.

That's disappointing. What method did you use to install it? I ask because I did not change the name of the rpm and that fact could be a source of confusion for rpm/urpmi.

To be sure, what I did was to remove both packages, wvdial-1.61-4.mga3 and lib64wvstreams4.6-4.6.1-7.mga3. Then, I installed the modified lib64wvstreams4.6-4.6.1-7.mga3 by giving urpmi the path to the rpm (url would work). Then, I installed wvdial.

It's all more of a mystery than anything else, to me. I only just made a stab in the dark about where and how to modify the spec file. Also, the connection I get looks valid but the network is unreachable :?:

by **mackowiakp** » Jun 9th, '13, 17:32

Hmmm. So I just install Your rpm by clicking on link in Your message.
As I understand, first I have to unsinstall wvdial, then install Your rmp and reinstall wvdial again. I am right?

by **rolf** » Jun 9th, '13, 17:54

Uninstall both, to copy what I did.

Get to be root in a terminal program. Do the following, and copy/paste the history of the commands and messages back here, in case there is some problem.

Code: Select all: urpme wvdial lib64wvstreams4.6

Then, you should be able to install my rpm by clicking on the link. Then, back to the terminal:

Code: Select all: urpmi wvdial

You should be able to see, in the terminal messages, the rpm is fetched from a Mageia mirror, maybe your DVD.

ISTR, in the past, using the gui software installer from the web browser, there is some situation, such as "package already installed" that does not get reported, so nothing gets installed.

by **rolf** » Jun 9th, '13, 18:32

Further to this, I performed the steps I advised in the previous message and wvdial works for me as reported. I am even allowed to use the internet after I workaround a separate problem in Mageia 3: https://bugs.mageia.org/show_bug.cgi?id=9723#c17

by **mackowiakp** » Jun 9th, '13, 18:37

I try both solution. Still the same error :-(

You did exactly this? Could you copy and paste the terminal contents from beginning to end for all this?

So You have. Sorry, but some wors are in my language but I think everything is understandable.

Code: Select all
urpme wvdial lib64wvstreams4.6

Then, you should be able to install my rpm by clicking on the link. Then, back to the terminal:

Your terminal shows that you skipped this step. Accordingly, urpmi installed the mageia rpm for lib64wvstreams4.6 from the mirror.

Code: Select all: $MIRRORLIST: media/core/release/lib64wvstreams4.6-4.6.1-7.mga3.x86_64.rpm

Start over, remove the two rpms with the first urpme command. Then, install my rpm. Just click on the link and let software installer do it. Then, install wvdial, which comes from the mageia mirrors, which is working, for me.

Code: Select all: urpmi wvdial

^^^^The very last move, installing wvdial by itself.

Thank You Mate! Its good to have contact with REAL expert.
WORKS!!!

by **rolf** » Jun 9th, '13, 20:27

Very good! I should go look at bugzilla and make or join a bug. Will report back.

There are updated RPMS for Mageia 3 in the Core/Updates_Testing repository. Enable the repository temporarily in Mageia Control Centre to install it.

If you could report back your experiences on bugzilla at https://bugs.mageia.org/show_bug.cgi?id=10470 it will help the QA team get it validated as an official update.

When building the update package I used Fedora's compile flags instead of Rolf's so it would be kinda nice to have confirmation that it works.

Thanks
