Hi, I'm getting this: acx._acx_issue_cmd_timeo_debug: phy0: cmd=ACX1xx_CMD_WEP_MGMT, buflen=52, timeout=49ms, type=0x0000, status=?: FAILED The card is acting as an AP. 3 Devices (dev_a dev_b dev_c) connect to it without any problem. 4th device (dev_d) fails and I'm getting the above message. If I disconnect e.g dev_c then dev_d is able to connect but then dev_c fails. Regards Dimitri |

Quite likely, indeed.
I've grepped all my (fairly extensive) archive of old acx mails
for the relevant strings below,
and I've never seen a 02 ID there in all the results, only 0x1x (e.g. RADIA)
by far.
Even directly grepping for "0x02\>" nowhere showed a radio string in the results.

From my prior experience, the D-Link cards (at least CardBus DWL-???650???) were
*a lot more often* prone to experiencing fatal corruption than other cards
(IIRC 3 to 4 cases, vs. only one somewhere else).
So I strongly suspect EEPROM corruption in your case, unless this hardware in fact *is*
a radio ID 0x02 (which I strongly doubt).
Next course of action:
- possibly examine card to determine actual radio chip ID
(or perhaps you've got existing driver CDs for this card
which would allow to gain more knowledge which radio it could be?)
- modify driver source to manually hard-code a different radio ID, then test whether that actually
works, when loading the correct corresponding firmware file(s)
- after successfully loading the driver, it {sh|c}ould be possible to gain dumps of the EEPROM content,
via /proc or /sys files as provided by the driver
That could be very useful to have
HTH,

I'm starting to get desperate trying to get my old D-Link card working, which is why I embarked on a quest to compile the driver on ArchLinux after unsuccessful ndiswrapper attempt. Unfortunately, it just so happens that the card reports a completely unambiguous radio ID, 0x02. I don't suppose this firmware file even exists.

Hello, We have upgraded the acx100 SourceForge project to the new SF Allura platform. The git repository URL got changed with this. The new URL is: git://git.code.sf.net/p/acx100/acx-mac80211 The old repo is still available read-only, but will receive no updates anymore. At this occasion also all open/pending tickets in the trackers were closed. Best Regards, Oliver |

Hi, The clarification of the legal question is currently still an ongoing project and within this context also contacts to TI have been established. Until now however there no consolidated status yet, but it will be followed up. Surely there are a number of reasons, why an mainline inclusion is desirable, also for this driver/hw.

Hi, This driver wasn't included into mainline linux kernel because of legal problems concerting the reverse engineering of the binary TI driver to develop this driver. One way was to ask TI to allow this driver being licensed under the GPL also if it could contain their intellectual property originally not covered by that license. [1] As TI started to work with the open source community some years ago and also works on a open source driver for some more recent wifi cards by them self, did someone recently (in the last few years) asked the TI guys if they could allow this driver to be licensed under the terms of the GPL, also if it could contain their intellectual property? I am currently not using this driver and I have to search for my cards I have last seen some years ago, but it really sucks to have an out of tree driver. If someone changes the API to mac80211 or any other in kernel API you have to adapt these changes by your self like this one: [2].

Actually monitor mode is currently not yet really supported (normally it's not set as supported in the interface_modes, but ok, that's a detail). Technically adding support for it should normally not be difficult and be mostly a question some skb handling and mode logic. The existing data-path is in general very stable and mac-wise we currently actually operate in a transparent rx/tx mode. The Rx-path is therefore probably already ready, Tx maybe not yet entirely.

I was running this card like 8 years ago, when this project was just starting, and it looks that again it is getting better shape. Maybe even it could be merged upstream in the end of this year :D (I do not know if legal issues are resolved about code, hope they are). As I ssaid, monitor mode is working, it just sometimes hangs system. It is probably some memory corruption, and once fixed should resolve probably many other problems.

You don't want to tell me that I should spend more time on this project? :-P
(in fact the WLAN side of things is a bit neglected,
thus I'll have some activity soon)

Yes (possibly):
linux/lib/Kconfig.debug:
config DEBUG_KMEMLEAK
bool "Kernel memory leak detector"
depends on DEBUG_KERNEL && EXPERIMENTAL && \
(X86 || ARM || PPC || MIPS || S390 || SPARC64 || SUPERH || MICROBLAZE || TILE)
select DEBUG_FS
select STACKTRACE if STACKTRACE_SUPPORT
select KALLSYMS
select CRC32
help
Say Y here if you want to enable the memory leak
detector. The memory allocation/freeing is traced in a way
similar to the Boehm's conservative garbage collector, the
difference being that the orphan objects are not freed but
only shown in /sys/kernel/debug/kmemleak. Enabling this
feature will introduce an overhead to memory
allocations. See Documentation/kmemleak.txt for more
details.
Enabling DEBUG_SLAB or SLUB_DEBUG may increase the chances
of finding leaks due to the slab objects poisoning.
In order to access the kmemleak file, debugfs needs to be
mounted (usually at /sys/kernel/debug).
IOW: enable DEBUG_KMEMLEAK, DEBUG_SLAB and SLUB_DEBUG. That will hopefully
aid in getting these things tracked down.
Thank you very much for your interesting and detailed report!

Hi, I am able sometimes to run monitor mode (airodump-ng) on my DWL-520+ using acx-mac80211 git driver, but often and repeatly see system hangs and other problems, probably releated to memory corruption. I'm running 32-bit Intel laptop (SMP kernel with heavy debuging running on single core Pentium-M CPU), with Docking Port with PCI Dlink DWL-520+ with RADIO0d.BIN and WLANGEN.BIN_1.9.8.b as firmware (download from archive.org version of erley.org). I will just show you few dmesg I got, and few other I written by hand: First this by hand: When running airodump-ng --channel 1 -w dump1 wlan1 somethin like: airodump-ng bad pagining when in __lock_acquire+1af call trace: ? sched_clock+8 ? sched_clock_local+f6 ? _raw_spin_unlock_irq ? lock_clock+65 ? trace_hardirqs_off_caller lock_acquire+89 ? net_tx_action _raw_spinlock_trylock ? net_tx_action net_tx_action ? __do_sfotirq __do_softirq ? __do_softirq __local_bh_enable [IRQ] ? ieee80211_configure_filter ? local_bh_enable_ip ? _raw_spin_unlock_bh ? ieee80211_configure_filter ? _raw_read_unlock ? ieee80211_do_open ? ieee80211_check_concurrent ? ieee80211_check_iface ??? ? ieee80211_opem ? __dev_open ? dev_set_rx_mode ? __dev_change_flags ? devinet_ioctl ? inet_ioctl ? packet_ioctl ? scok_ioctl ? sock_fasync ? do_vfs_ioctl ? remove_wait_queue ? do_wait ? fget_light ? sysenter_exit ? sys_ioctl ? sysenter_do_call and kernel panics and hangs after that. Sorry for manually printout, but my second computer have some problems so was unable to run console over serial line to have full kernel message avaialble. I belive last dmesg message w acx ... Updating to mode=0x00ff This is easy to reproduce, and happens 75% of time I use airodump-ng, it is probably one of the first ioctl done on interface to put it in monitor mode. Other one is like this bad paginign request ksoftirqd/0 (I was doing apache stop basically) in __lock_acquire+1af call trace: ? sched_clock+8 ? sched_clock_local+f4 ? trace_hardirqs_on+b ? local+clock+65 ? trace_hardirqs_off_caller lock_acquire+89 ? net_tx_action+d3 _raw_spin_trylock+64 ? net_tx_action+d3 net_tx_action+d3 __do_softirq+9b ? run_ksoftirqd+d5 run_ksoftirqd+e7 __do_softirqd+e7 kthread ? kthread_worker_fn+170 kernel_thread_helper+6 just before last kernel message is from acx: Updating to mode=0x00ff Other bug is like this (begining is just booting): ...

System in this case was still running, but for safety I rebooted it. However system can hang even in other circumcances, like just stoping apache! (which probably listens on *:80). It looks like memory corruption, but do not know how to start debuging it. Maybe more debuging message in ioctl handling? Any ideas? -- Witold Baryluk |

hi all,
Ive installed an acx111 based mini-pci card into a box running voyage 0.80+
(daily build from Nov 2011), and am getting partial success:
- driver loads & recognizes the device
- it wont connect to the AP
Device ID is below, I sent the whole /proc listing cuz other parts
might provide a clue as to whats missing.
There is a "failure" in diag, dont know what it means.

Also, <debugfs>/ieee80211/phy* is empty.
whats interesting here is that I have another
wifi card in the same box, its working, and
its dbgfs entry is also empty. That suggests
its the box/kernel/userspace thats responsible.

I'm still trying to work out exactly where the problem is. Originally my phone had intermittent connectivity issues with large downloads over wireless to the internet (via my DG834Gv2). Then I tried downloading large files from my home webserver onto my phone (again via wireless) and I discovered that it would regularly lock up too (ok, so it's not an internet problem). Then I thought that it might be a "wpa" issue, so I set up a test network with no wireless security (I have a couple of spare dg834g routers floating around!) and just a linux webserver on the lan and I got exactly the same problem (so I assume it's not a wpa issue). I've just tried reflashing the original Netgear firmware (3.01.38 for us UK folk) and again I'm getting the same problem. As a result, I now think it's an android wireless driver issue. Perhaps my best best from here is to see if there's a more up-to-date ROM (with upgraded wireless drivers) available for my phone! Thank you again for all the work you've done on the acx-mac80211 drivers - I am very grateful to you (and I'm sure many others are too.) With kindest regards, Jaime |

Hi Jaime, Just tried on an DG834G v2 with the current driver version (commit 09bebfd), which is also the uptodate version in the OpenWrt trunk, but I don't observe these delays, neither from pings AP->STA nor STA->AP, see below. The kernel etc. however of my installation is still an older trunk version ... I would still need to update this and make another test. If I understand correctly, other clients respond normally to pings from the router, just the phone shows longer delays. Did you already try the phone with other APs, if these delays can be observed there as well ? How is it with other traffic patterns, like e.g. an ssh or scp from the router to the phone ? Difficult to say if it's something with the driver - maybe, but I never observed this with clients here. I'm just wondering, if the wifi of phone could maybe snooze down on low activity, and therefore react with an higher initial latency. That could go inline with the fact, that activity initiated from the phone decreases the delays. But it's just a guess. You could also try to monitor the wifi 802.11 frames with a third station and e.g. wireshark, to see if the router and phone indeed send their respective data/ack frames. I tried that below on a WPA2 link.

Hi. Thank you to all the developers that have worked on the drivers for the wireless chip in my Netgear DG834G (v2) ADSL wireless router. I'm using Openwrt's trunk on the box and wireless works well. I get packet-loss problems, however, with one of the wireless clients. If I ping from the router to my android phone, I get the following kind of result (the packets between seq# 16 and seq# 260 disappear): root@OpenWrt:~# ping 192.168.0.134 PING 192.168.0.134 (192.168.0.134): 56 data bytes 64 bytes from 192.168.0.134: seq=0 ttl=64 time=5981.923 ms 64 bytes from 192.168.0.134: seq=1 ttl=64 time=4980.768 ms 64 bytes from 192.168.0.134: seq=2 ttl=64 time=3984.334 ms 64 bytes from 192.168.0.134: seq=3 ttl=64 time=2983.757 ms 64 bytes from 192.168.0.134: seq=4 ttl=64 time=1983.329 ms 64 bytes from 192.168.0.134: seq=5 ttl=64 time=982.866 ms 64 bytes from 192.168.0.134: seq=6 ttl=64 time=2.305 ms 64 bytes from 192.168.0.134: seq=7 ttl=64 time=3987.770 ms 64 bytes from 192.168.0.134: seq=8 ttl=64 time=2987.478 ms 64 bytes from 192.168.0.134: seq=9 ttl=64 time=1989.163 ms 64 bytes from 192.168.0.134: seq=10 ttl=64 time=988.934 ms 64 bytes from 192.168.0.134: seq=11 ttl=64 time=2.360 ms 64 bytes from 192.168.0.134: seq=12 ttl=64 time=3999.889 ms 64 bytes from 192.168.0.134: seq=13 ttl=64 time=3000.279 ms 64 bytes from 192.168.0.134: seq=14 ttl=64 time=2006.232 ms 64 bytes from 192.168.0.134: seq=15 ttl=64 time=1006.624 ms 64 bytes from 192.168.0.134: seq=16 ttl=64 time=5.243 ms 64 bytes from 192.168.0.134: seq=260 ttl=64 time=2022.973 ms 64 bytes from 192.168.0.134: seq=261 ttl=64 time=1024.080 ms 64 bytes from 192.168.0.134: seq=262 ttl=64 time=24.571 ms Does the regular pattern of time delay mean anything to anyone?

Is there anything that I could do to improve the wireless connectivity? I appreciate that I haven't given lots of info to work with - if a tcpdump capture from a third host would help, please let me know. With kind regards, Jaime |

Hi Jim, Thanks a lot for the feedback also from from here! Good to hear that the driver worked out nicely for you (so as it should ;). I'm a bit busy with hx4700 works currently. The acx part of it worked already since quite some time - it's more the general hx side. The acx work also continues, but it's just a bit shared with the hx currently ;).

Not true, I'd think. The card firmware _itself_ is restricted to being able to handle WEP only, but since the card ought to have fully transparent framing (as expected by several existing monitor mode software users!), it should be able to carry any host-CPU-produced protocol. Thank you for your nice step-by-step report! (I'm sure some guy or another will have good use for it) Andreas Mohr |

I am pretty impressed with the acx100 project. I was able to get a TI
ACX100 card to work with a semi-recent distro and kernel. Most
impressively, it seems to support CCMP (that is, WPA2 or AES).
There's no driver I can find for this card for Windows 7 nd the newest
XP driver I can find can only do WEP! But the acx-mac80211 branch worked
perfectly.
I checked out rev 90ac19873ca14bcf9f6c2c4f3d15feb4ec102ba1 of the
acx-mac80211 branch (at that time, it was HEAD).
This is the kernel that KNOPPIX 6.4.3 uses:
Linux Microknoppix 2.6.36.1 #10 SMP PREEMPT Fri Nov 26 10:33:59 CET 2010
i686 GNU/Linux
It also uses this version of gcc:
gcc (Debian 4.4.5-4) 4.4.5
Card info from lspci -v
05:00.0 Network controller: Texas Instruments ACX 100 22Mbps Wireless
Interface
Subsystem: Tekram Technology Co.,Ltd. Device 1801
Flags: bus master, medium devsel, latency 64, IRQ 11
I/O ports at 1800 [size=32]
Memory at 20010000 (32-bit, non-prefetchable) [size=4K]
Memory at 20000000 (32-bit, non-prefetchable) [size=64K]
Capabilities: [40] Power Management version 2
Kernel driver in use: acx_pci
The card itself is a Gigafast WF721-AEX Txxx, bought many years ago.
(The original company no longer seems to exist.) Perhaps there was
something unique in the hardware of the WF721 that allows it to do
CCMP. I was under the impression that the TI ACX100 could only do
WPA1/TKIP due to hardware limitations (as mentioned in this thread:
http://aptosid.com/index.php?name=PNphpBB2&file=viewtopic&p=3583 ,
which I found by a simple Google search).
(A write-up of my first attempt to use this card, back in 2005, is
available here: http://www.ko4bb.com/Linux/Gigafast_WF721-AEX/ )
I also grabbed the firmware from
http://www.kazer.org/acx-firmware-20060207.tar.bz2 (I took this from the
gentoo net-wireless/acx-firmware ebuild). I'm using the acx100_1.10.7.K
firmware. tiacx100 tiacx100r0D tiacx100r11 installed into
/lib/firmware.
Finally, here's my wpa_supplicant.conf. I start wpa_supplicant manually
with this command line:
wpa_supplicant -ddd -Dwext -iwlan0 -c
/etc/wpa_supplicant/wpa_supplicant.conf
And the file itself:
# Minimal /etc/wpa_supplicant.conf.
# Managed by KNOPPIX.
# Please see
# /usr/share/doc/wpasupplicant/examples/README.wpa_supplicant.conf.gz
# for more complete configuration parameters.
#
# Also see the other files in /usr/share/doc/wpasupplicant/examples/ for
# specific configuration examples.
# path to UNIX socket control interface
ctrl_interface=/var/run/wpa_supplicant
# Scan for accesspoints, this may be required for hidden ssids
#ap_scan=1
#fast_reauth=1
### Example of basic WPA-PSK secured AP
network={
#scan_ssid=1
ssid="myssid"
#proto=WPA RSN
#proto=WPA
#proto=WPA2
psk="mypsk"
key_mgmt=WPA-PSK
#auth_alg=OPEN
pairwise=CCMP
group=CCMP
#pairwise=TKIP
#group=TKIP
}
It works quite reliably.

Oh okay, I see now that STA means station, as in client. Always found the wireless terminology a bit confusing. :) James |

I'm not sure exactly what you're asking for. Here's what I get from
iwconfig on the Netgear, which is acting as a client.
wlan0 IEEE 802.11bg ESSID:"AuraNet"
Mode:Managed Frequency:2.427 GHz Access Point:
00:0F:B5:72:06:B6 Bit Rate=24 Mb/s Tx-Power=20 dBm
RTS thr:off Fragment thr:off
Encryption key:off
Power Management:off
Link Quality=19/100 Signal level=19/100
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:5 Invalid misc:131 Missed beacon:0
And here's what I get on my PC, which is acting as the access point.
wlan0 IEEE 802.11bg Mode:Master Frequency:2.427 GHz Tx-Power=20
dBm Retry long limit:7 RTS thr:off Fragment thr:off
Power Management:off
I notice that my laptop sometimes has a bit rate of 54Mb/s but this
jumps around a bit. It may be that the p54usb-based Netgear dongle I
use for the access point isn't all that great. It works well enough
though.

Thank you very much for your hard work, Oliver. :). Great, sounds good ;)! It's about the figures I see here. Part of it is probably also due to the rate auto-fallback that came in some commits ago. For the logs, it also because the logging got a bit tuned itself, but the auto-fallback also reduced it already before. What do you actually see on the STA side as signal level? My ath5k here measures 'Signal level=-75 dBm', with approx. 5m and a wall in between. I don't think it's a super strong signal yet, so probably the overall link quality could still increase, if the tx-level could be raised. > Just so you know, I used OpenWRT rc, which is the latest from the > Backfire branch. I didn't make any changes beyond replacing > acx-mac80211 with the newer version. Alright, good to know with the Backfire branch, so that's probably a difference with trunk. G+, Oliver |

Well I finally dug out the old machine and got it working. This is a MASSIVE improvement. iperf reported 421KB/s in one direction and 337KB/s in the other with NO nasty messages in the kernel log. Brilliant! Thank you very much for your hard work, Oliver. Just so you know, I used OpenWRT r24978, which is the latest from the Backfire branch. I didn't make any changes beyond replacing acx-mac80211 with the newer version. Regards, James |
