Bugzilla Bug 174693

Since I emerged it, iwevent dumps core on every event, also, iwlist eth1
scanning produces buggy output, with "Unknown/Bug" in the ESSID place, etc.

Not sure what's going on, but _pre17 looks buggy



Reproducible: Always




_pre10 works very well, kernel gentoo-sources-2.6.20-r4

What driver are you using?
I'm seeing similar behavior with the rt2500 driver myself.

I have ipw3945 here. Reverting to _pre10 makes it work right again.

This appears to be an amd64 issue, not overall.

     Hi,

     It's all my fault, please blame me.
     Here is the deal. I don't have any 64 bit platform. A few weeks ago, a bug
on PPC64 with 32 bit userspace was reported. I attempted to fix it. Well, it
now seems obvious that I broke AMD64.
     First, I would like to thank you for the bug report. Good bug report are
what helps us make good progress ;-)

     I've just uploaded a new version of WT, 29-pre18. It does not fix the
problem, on the other hand 'iwlist scan' should printout some information
useful for me to diagnose the issue and devise a fix.
     Just compile, run 'iwlist scan' and tell me what it says...

     Sorry again for the breakage...

     Jean

iwlist scan output

      Hi,

      After a few debugging sessions with Roy (thanks for his help), I think I
understand what's happening, and I think I have a fix for it. I've uploaded a
new version, 29-pre19, that should have the fix.
      You are welcomed to test and report ;-)

      Thanks again for your patience...

      Jean

Fixed in pre20.

Works as a charm here. Cheers to Jean for sustained excellence :)
