Export the non-shifted target_pf value to debugfs, so that it's human-readable.

Hey,

I'm a little late on this and away from my development machine anyway, =
but when reading my email, I noticed the following and thought this is =
important enough to point out, even though I only have that crappy webm=
ailer and the only kernel tree I can look at is wireless-2.6/everything=
 on git.kernel.org

In rc80211_pid.h, you have the following (this from the wireless-2.6 tr=
ee):

        /* Sampling period for measuring percentage of failed frames. *=
/
        #define RC_PID_INTERVAL (HZ / 8)

But rc80211_pid_algo.c says:

        period =3D (HZ * pinfo->sampling_period + 500) / 1000;
        if (!period)
                period =3D 1;

You see this is completely bogus. My original patch had:

        /* Sampling period for measuring percentage of failed frames in=
 0.001s. */
        #define RC_PID_INTERVAL 1000

You see why what you posted and John commited is bogus?

I'm getting a little fed up with this, you keep screwing up the code wi=
th my name on it *sigh*

And again, I still don't think guarding against period =3D=3D 0 is the =
right thing to do. As I explained privately in IRC, we should make sure=
 the sample_interval is larger than HZ when setting the sample_interval=
 variable  (once nl80211 is done). It doesn't make sense to do this che=
ck every time we execute the code when we can do it once in advance.

Sigh.

Indeed. I didn't notice about this because HZ == 1000 on my laptop. But I
didn't even sign off that patch, I just added a From: on top of it,
and changed this:

+#define RC_PID_INTERVAL (HZ / 1)
[yes, this is present in your original - as sent through IRC - patch]

to:

+#define RC_PID_INTERVAL (HZ / 8)
[and IIRC we discussed about this on IRC]

I'll post a fix for this.

> I'm getting a little fed up with this, you keep screwing up the code with

Please, could you show _exactly_ which patches with your name (as in,
From: you) you think I screwed up?

I don't think I screwed up anything yours. I would be very sorry otherwise.

Exactly, once nl80211 is done. Now, what if the control interval gets
changed after initialization? How often should we check whether it's larger
than HZ? If you got another solution which would work together with the
current debugfs interface, please post it.

> Sigh.

Please stop this. I think that this is:
1) not correct (but I don't care that much);
2) useless;
3) confusing.

Sorry again if I actually screwed up anything.

Simplify and fix rate_control_pid_shift_adjust(). A bug prevented correct
mapping of sorted rates, and readability was seriously flawed.

Set a better value for percentage target for failed frames. The previous value
slowed down too much rate increases in case of permanently low activity. While
at it, increase readability.

While tinkering with a sta_info refcounting bug in rc80211-pid algorithm, I
discovered that calling sta_info_get() and then sta_info_put() right after
would cause a kernel panic on my uniprocessor, preemptible kernel. I
couldn't set up netconsole, however, most of the trace is reported below
(my camera did its best, as the trace wouldn't fit on the screen and I
couldn't scroll, so wasn't able to see the first part with naked eyes :).

So I guessed that locking was lacking somewhere. The following patch fixes

It'd be good to know actually, along with disassembly.

Definitely not. If you look at the code in question, it has nothing at
all that needs locking. It's not accessing any shared structures at all.

I now removed the lock, rebuilt my quilt tree, rebuilt mac80211 and I can't
reproduce it. I think that could have been my fault, I should have did
something wrong such as calling sta_info_put() twice or somesuch. Sorry for
the noise. Will poke you again if I happen to reproduce this.

[-- Attachment #1: Type: text/plain, Size: 662 bytes --]

Hi,

The Lenovo Thinkpad Tablet 10 is a complete disaster under Linux, and
among many problems the SDIO brcmfmac wifi does not work.

I get the following messages in the kernel log:
brcmfmac: brcmf_sdio_drivestrengthinit: No SDIO Drive strength init done
for chip 4324 rev 6 pmurev 17
brcmfmac: brcmf_sdio_htclk: HT Avail timeout (1000000): clkctl 0x50
[repeated]

and the network interface is never created.

I'm running kernel 3.18.4, my brcmfmac43241b4-sdio.bin is identical to
the one in the linux-firmware repository, and I have attached the
brcmfmac43241b4-sdio.txt that I have extracted from the EFI variables.

Any help would be appreciated.

Sébastien

When you say your firmware is identical what does that mean. Did you do 
a diff? Can you do 'hexdump -C brcmfmac43241b4-sdio.bin | tail -30'? I 
will be getting a laptop with 43241 integrated soonish (monday?). 
Hopefully it has same chip revision.

Regards,
Arend

Hi Arend,
I am still experiencing the issue Sebastien initially described (no wlan0 device,
"SDIO drive strength" warnings etc) on a Thinkpad Tablet 10 for the latest
kernel release, 4.2. Doesn't the 4.2 kernel include the required fix?

Thanks,
Oleg

Hello,
I have been trawling the mailings and lots of people are asking about 802.11p and I have not managed to find a definitive push back to the mainline kernel.

Is there anywhere in particular that I need to be looking to be able to get the patches so I can have a play ?

Thanks
Marc

Hi,

first of all, you should set a "subject" to your email request :-).

I cannot say much about 802.11p, but for first informations I
recommend the wiki at <http://wireless.kernel.org> and have a look
into docs section.

For faster replies you can join #linux-wireless IRC channel (Freenode).

780 bytes on stack isn't a great idea.

Out of memory isn't really true.
The packet size is just too big for your
little buffer.

Looks to me like this should be dev_dbg not dev_info

The subject did not show in my mailbox. Not sure if necessary, but I 
tend to send patches to a maintainer and CC the appropriate list(s). So 
the nfc list as well (linux-nfc@lists.01.org).

Arend

I suspect this is a copy-paste error right? Should be 
obj-$(CONFIG_NFC_BCM2079X_I2C).

Thanks for cc'ing me. Yes, the NFC maintainers emails and the mailing
list are in the MAINTAINERS file, so I expect people to use them to post
their NFC related patches.

Jeffrey, I appreciate the upstreaming effort, but I'm not going to take
this patch. It's designed for Android exclusively and not using any of
the NFC kernel APIs.
In particular, we have a full NCI stack that you could use. There
currently is an SPI transport layer, adding an i2c one would be really
easy.
If you're interested and can spend some cycles on this, I can surely
help you with the kernel APIs and how your driver should look like.

Cheers,
Samuel.

Hi Kernel Maintainers,

Tried to report this properly via email but got some formatting issues
coming back, I've attached the content of the original email report as
'Report.txt'.

It is the same file as found on comment 12 on Launchpad bug.
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1142385

Apologies for any missing information or lack of reporting experience :)

B43 Wireless Autoconnect Failure

I installed raring to test whether this bug existed in it and quantal too.
In the 3.8+ kernels there seems to be an issue with the b43 drivers, my
wireless works however it won't automatically connect to my hidden wireless
network. I have to go into network manager on each login and manually
select the option to connect, it takes a while but then the connection
works fine.
I know this didn't exist in 3.7.x because I was using those kernels
absolutely fine, it's only when I tried 3.8 on both quantal and raring that
the issue arose.
Note: I can't edit the wireless settings on my network as I am not the
administrator in my house.

Sending e-mail with empty subject and without direct information about
the hardware isn't a good idea.

It's most probably another result of regression I've tracked and reported in:
Scanning regression since "cfg80211: use DS or HT operation IEs to
determine BSS channel"

http://www.spinics.net/lists/linux-wireless/msg105359.html
http://marc.info/?t=136431795000003&r=1&w=4

I didn't have enough time to debug it further and fix yet.

These patches improve/fix HT handling, particularly the bandwidth
change handling that we were missing entirely and HT capability
handling (which touches many drivers, unfortunately.)

This should make the VHT handling compliant with D4.0, I hope.

I did a little bit more testing and applied all.

Hi,
I have linux evolution  and I had a normal wireless connection until
something changed in maybe network settings and it just stopped

Vlatka,

I have some suggestions for you.

First, never submit an E-mail to anyone, and especially to a mailing list 
without a subject that is a good description of your problem. Most experts will 
have their mail filters set up to direct a subject-less message directly to the 
spam bucket. I think I need to do that too.

Second, you give no information that would let anyone help you. "It just stopped 
working" does no good. Knowing what changed is critical. If the kernel changed 
when it stopped, then this list might be the right place to ask. If something 
was updated by the distro, then get your help there as very few of us would know 
how evolution works. if nothing changed, then your settings just got corrupted, 
and you definitely need to contact the support at evolution.

If you think that it is a kernel or driver problem, then you absolutely must 
state what hardware you have, what driver it uses, and the PCI or USB ID that 
describes it. You also need to state what kernel works, and what version fails.

Larry

Since the update from linux 3.2.1 to 3.2.2, dhcp stopped working on
some APs on my laptop with an AR9285 Wireless card.

dhcp works fine on an open wifi network but receives no response on a
wep network I use. I haven't been able to test it on a third network
for now.
Reverting to 3.2.1 solved the issue which is still there in the latest
git revision as of today.

DHCPDISCOVER requests are still sent but no ACK is received (nothing
in Wireshark).

dhcp failure may be one particular instance of the problem but I
haven't been able to connect with a static ip (my ap doesn't like it)
so this is the
only result I know.

 reverting  "ath9k_hw: fix interpretation of the rx KeyMiss flag" does
helps.  i  need to analyze
if it exposes some real issue which need to be fixed.

this seems to be a problem in WEP alone, where the key miss is always
set for this case and RX_FLAG_DECRYPTED is not set. mac80211 trys to
decrypt,  but fails due to ICV mismatch.

OK...any way to differentiate this case at that point in the code?

unfortunately as the rx_keyix is always 'INVALID' (as obtained from

You're right. I read up on what the other codebases do here, and I have

The WPA-PSK association was not going through with 2.6.38
kernel. It was found that supplicant was not able to set
the PTK key. On further analysis it was found that the function
nl80211_set_key in file net/wireless/nl80211.c is returning with
code as -EOPNOTSUPP. This function has been modified to check for
the flag "WIPHY_FLAG_SUPPORTS_SEPARATE_DEFAULT_KEYS"in wiphy
struct. If this flag is not set in the driver init, it returns
from here thereby causing the association to fail. The solution
is to set this flag in driver init as there would be separate
default keys for unicast and multicast packets.

We were discussing this before ... and I think the bug is in the
supplicant actually asking for the GTK to be set as the default key or
something like that.

In any case, this doesn't seem right unless you actually do support
separate unicast keys. Are you sure you fully understand what you're
doing here, and not just randomly hacking in a workaround?

Hello,

I am seeing some weird behavior with the iwlagn driver from linuxwireless.com:

My Intel 5300 wireless card will randomly disassociate itself from the
access point. It happens with or without security enabled. It only
happens when using the 802.11n mode. I've noticed that the further
away I am from the AP, the LOWER the chances of this to happen. If I
put my laptop within 2-3 feet from the access point, the wireless card
will disassociate itself on average once every 30 seconds.

Here is some data:

This looks similar to https://bugzilla.kernel.org/show_bug.cgi?id=15374
- could you please update your kernel to 2.6.33 and try the patches
attached to that bug report?

Reinett,

Thanks for responding to this. I also noticed other things. It seems
that this Microcode SW error occurs because the wifi card is
overheating. When used in n-mode and there is a large file transfer,
the temperature of the card rises to over 62C. Soon after this, the
microcode error occurs and the card gets disassociated.

Doing more research on the power vs temperature problem, I discovered
that other users are seeing this as well. Some have solved their
problem by enabling the power management for the wifi card by issuing

iwconfig wlan0 power on

Others, completely disabled the power management and forced a fixed,
lower power level by issuing

 echo 8 > /sys/bus/pci/drivers/iwlagn/0000\:06\:00.0/power_level

Also, what I have noticed is that if I have my laptop very very close
to the Access Point (1-3 feet) then this error is more likely to
happen. If I move the laptop further away, say more than 15-20 feet,
this error stops occurring so frequently.

Unfortunately, I cannot upgrade to 2.6.33 kernel as it is currently
not available for my distribution and I am reluctant to recompile my
own kernel.

I am not familiar with these workarounds. Could you please submit a new
bug at http://bugzilla.intellinuxwireless.org/ or add your information
to a bug in this system if you find one that is related?

The zd1211rw does not work with the Shuttle PN15G (D-Link Corp. WL54).
After the driver fails it also break the device for my windows XP
install.
To get it back in working order I have to physically re-plug it while
windows is running, this is pretty annoying as the PN15G is meant to be,
and is, built inside my shuttle box.

I tried another device that uses the same driver, the ZyAIR G-220, and
it works like a charm.

- Is there a way to get the Shuttle PN15G working ?
- Can prevent the driver from breaking my device, so it will remain
working under windows XP.

Are you sure this is a ZD1211B, not a regular ZD1211? Try changing the
USB ID definitions to mark this as a ZD1211.

Ah, good point -- I think I may have inadvertently encourage this
order. :-(

It looks like you'll need the other order -- be mindful of the
BUILD_BUG_ON I pointed-out in the previous email!

John

P.S.  Hmmm...anyone want to add a kerneldoc entry for RFKILL_TYPE_GPS?

Sure, but please do a different patch for that.  Make it the first
one, so that it can be applied even if there is still a problem with
the other patch.

Thanks,

John

Decoded version:

The rtl8187se is not supported by the mainline driver.  There's a
driver for it in staging though, and there's a vendor driver hosted
here:
http://code.google.com/p/msi-wind-linux/
...I would try to build and load that driver for now.

The driver in staging _IS_ the vendor driver with a leak in the procfs fixed and
the code brought up to the latest kernels. It will work. There is no need to use
the vendor driver and to redo those fixes.

I am working on an rtl8187se driver that uses mac80211 and that will be suitable
to be included in mainline kernels. I estimate that I am about 25% done.

The error happens because config.mk checks for your kernel release and
if it detects its you are using a kernel release <= 2.6.22 it'll stop
and error out with that message. The problem is there is an oops
(kernel crash) that will occur if you enable the compile to go through
and use it. The error indicates to you that if you want to try to fix
the issue you can remove the force check on config.mk.

I used to support 2.6.22 but distributions have newer kernels so I
rather focus attention on newer kernels as we move forward. This gives
the opportunity for those developers interested in using 2.6.22 to go
ahead and fix it if they wish.

If you are a user I'd recommend to upgrade to at least 2.6.26.

I just compiled 2.6.25-rc6 and got a bunch of warnings when I did make modules_install. I am using a PC not a laptop so I don't bother compiling PCMCIA support.

Just remove /lib/modules/2.6.25-rc6 and reinstall the modules.  It's  
probably modules installed by compat-wireless that were compiled for a  
kernel with the same version but different settings.

During testing of bcm43xx interference mitigation, two problems were
discovered:

(1) When the MANUALWLAN mode was set, routines _stack_save and _stack_restore
    generated assertions that were traced to saving ILT registers with addresses
    > 0xFFF. This problem was fixed by adding one bit to the field used for
    the offset, and subtracting one bit from the space used for the id.
(2) In MANUALWLAN mode, the IRQ XMIT errors are generated. The cause of these
    errors has not yet been located. Any suggestions on debugging this problem
    would be greatly appreciated.

Interference mitigation code is broken and has always been. It never worked.
So no wonder it doesn't work now. ;)
I'd suggest to first fix that (by a rewrite) before you do any code
that's based on it (like this ACI stuff).

I won't do it. interf mitigation is an uninterresting feature to me.
