[Lev R. Oshvang .]

Hi people.
Today I've sent my first patch - Add file suffix selector as an IMA policy rule
My apologies for the possible errors I made fighting with mutt.
I deleted FROM line of the format patch because I thought it is wrong,
here the line:
From b84152f969c6d0555486f3c78e1dd374f05bbe18 Mo Sep 17 00:00:00 2001

Please advise me whether this line is necessary.

Hi there,
We have never met before but I am Doctor Halilovic from Australia 
currently in South Gaza. Please may I kindly know your name and 
where you are from? I know it can be annoying getting emails from 
people you do not know. Still, I am getting in touch because I 
wanted to discuss an opportunity for us to connect and 
collaborate. I can be reached via my email address:

When I try the command 
 iwconfig wlan0 essid "lago" mode Ad-Hoc 

show me 

Error for wireless request Set Mode (8B06) :
    SET failed on device wlan0 ; Device or resource busy.

But if I connect with for example 

iwconfig wlan0 essid "dip-open" #my university wireless connection it works, and very well.

For this I have no explanation

With mac80211 you need to change wireless mode only when the interface
is down.

$ ifconfig wlan0 down
$ iwconfig wlan0 mode ad-hoc
$ ifconfig wlan0 up

Maybe.... but don't work... from the version 0.0.36 to no tell me 

Impossible to set ...etc etc.... at the first occasion I will post up the error code that give me...

No, there is ad-hoc support in 0.1.4.

Re: Request for help...

[Axj]

I've tried the driver 0.1.4 with the new (not so new) linux kernel 2.6.22.1 (against the 2.6.21.5 installed on Slackware 12, and it work without any patch. In fact,  at the moment of compiling kernel the mac80211 subsystem is already in..... now it works (even if no led and no Ad-Hoc). I really don't try 1.0.0. I will do it. Maybe the fact of the led in only because I don't pass the right option to the modprobe (in ipw2200 was "modprobe ipw2200 led=1") but here is not. For the Ad-Hoc, i try to take a look in source, but maybe isn't present this part or I don't find. 

By the way, thank you for the advice and suggestions

Actually, it's direct continuation of the 0.0.x series.  It's
unfortunate that the complexity of the build system makes you mistrust
the recent code, although I can relate.  I hope it will be remedied
quickly.

It's possible to compile the 1.0.x driver against recent unpatched
kernels, even against the standard Fedora 7 kernel, by stripping support
for Intel's rate control algorithm:

I tried, but peraphs I do someting wrong.... In fact without mac80211-9.0.x is impossibile to compile iwlwifi-0.1.3. But for me I'ts impossible to compile mac-802-9.0.2... give me 2 compile errors when I do "make modules", in the wmc.c. Now, if use the "make patch_kernel" of version of 9.0.2 and compile iwlwifi-0.1.3 it copilke perfect but at the moment to load the module, search a Object that doesn't exist (because if I don't compile the 9.0.2 I have to use 8.0.2). So, if I undestood good, the only way to use the driver version 0.1.x and not the version 0.0.x, is to make work the mac80211 version 9.0.2, and to resolve the compilation problem. It's no so simply like seems to be.

I  saw onother exit of thje driver, 1.0.0, but I don't trust so much (at the momente the compination of mac80211 ver 8.0.2 and iwlwifi-0.0.42 work, even if the led doesn't work ad It's impossible to set an "Ad-Hoc" connection. ) so I would like try a CVS or GIT version of the Mac80211 or newer.... I know that a lot of person think that I have to "learn to fish", but I'm a better systemist, but not a excellent programmer (expecially in kernel space). 

I would like to tel You tank you for the help.... 
I hope that one day I will give you as better answer....

Re: Request for help...

[John W. Linville]

Since Intel continues to develop their mac80211 fork
on their own, you will have to seek support from them at
ipw3945-devel@lists.sourceforge.net.

I keep hearing that Intel intends to come back to working with the
community on mac80211.  Alas, that has yet to happen.  I want to
believe that it will soon...?

Hi, I'm alex....

I have a notebook Acer Aspire 5920G, with an intel 4965 wireless, system is a Slackware 12 and kernel is my personal recompiled version of 2.6.21.5. 

Usually I use the drivers of the version 0.0.* with macsubsystem version 8.0.2, but I've tried to compile the version 0.1.2... a lot of compilation problem. So I think to use  mac9.0.2..... 
after the make modules of these it's arrived this message.... 


net/mac80211/wme.c: In function 'ieee80211_ht_agg_queue_add':

net/mac80211/wme.c: In function 'ieee80211_ht_agg_queue_remove':

make[2]: *** [net/mac80211/wme.o] Error 1
make[1]: *** [net/mac80211] Error 2
make: *** [net] Error 2


so I can't compile the new version, but, even if the compilation is not finished, when I retried to compile iwl version 0.1.2, it works. Now for me is impossible to  understand, and I'm tring the way to make mac802 subsys work. Can anyone help me....

Another little question... exist a way for make work the wireless led that is always off, even if the wireless works.

Sorry for the request and for the the bad english... it's a lot of time that I don't wrote to a english mailing list (the last was alsa).

 Hellow sir,

        I have downloaded ur xen-2.0 source code and tried to compile
  it in my system. But i received many errors. First the macros in the
  .s files in xen-2.0/xen/arch/x86/boot/x86_32.s are not expanded.Thus it gave the error.
 The same thing happened in xen-2.0/xen/arch/x86/x86_32/entry.s file.
 Then this gave the errors like "undefined reference to do_divide_error" etc. Will u please help me by sending the details of how to solve the problem?

My system configuration is,
   Pentium-4 2.4GHz
   256 MB RAM
 I am waiting for ur mail. Please help me sir.

Thanking you,
Shashidhara Bhat

If you can wait until *after* the system has booted, there are lots of
ways to derive what is out there.  Grab the sources for "hdparm" and
have a look at it for examples of hardcore access methods.

A simple way to derive some information can be found by walking the
sysfs hierarchy.

Here's a dirt-simple script I use that somewhat-pretty-prints items
hanging off busses in the sysfs hierarchy.  Sysfs must be mounted for
the script to work.

Sample output:

Re: Request for help

[Eric W. Biederman]

I am CC'ing linux-kernel as that is the general kernel list.  There
may be something even more focused on IDE issues but I am
not aware of it.

Yes.  But it is baroque.

Not exactly.  The method is essentially you ping the drives to see
if they are there.

Nope this information is not stored in registers.

No.

But there is also nothing that allows you to force the module
order within the kernel.  So there are no guarantees you will
come before a normal IDE driver.  I assume from the questions
you intend to have this working in the linux kernel.
