brcmfmac: brcmf_p2p_create_p2pdev: timeout occurred

[Jörg Krause]

Hi,

I've trouble creating the p2p interface on a BCM43362 wifi device
running Linux kernel 4.0.4:

    # dmesg | grep brcmfmac
    [    7.010870] brcmfmac: brcmf_c_preinit_dcmds: Firmware version =
    wl0: Apr 22 2013 14:50:00 version 5.90.195.89.6 FWID 01-b30a427d
    [    7.158905] brcmfmac: brcmf_cfg80211_reg_notifier: not a ISO3166
    code
    [   11.007164] brcmfmac: brcmf_p2p_create_p2pdev: timeout occurred

Trying to add the p2p interface manually:

    # iw phy0 interface add p2p0 type __p2pdev
    [  372.042704] brcmfmac: brcmf_link_down: WLC_DISASSOC failed (-52)
    [  373.637263] brcmfmac: brcmf_p2p_create_p2pdev: timeout occurred

    [  373.685733] brcmfmac: brcmf_cfg80211_del_key: invalid key index (5)

Any idea?

Best regards
Jörg Krause

Wondering whether it is similar to what Rafal reported. Can you do a 
hexdump, ie. hexdump -C brcmfmac43362-sdio.bin | tail -30

I managed to set up the p2p interface by recompiling the kernel with
CONFIG_BRCMDBG and loading the brcmfmac module with p2pon=1.

I had a discussion some month ago with Hante Meulemann about setting up
the p2p interface. This is one of his replies:

    "For what I can see from the log is that we don’t get the event from
    the FW indicating that the p2p interface was created. This probably
    means that there is a bug in this FW for this device. I need to discuss
    this to see how much priority we can give this. The best option for you
    for the moment is to use the legacy method with the 'p2pon=1' command."

Thanks for digging your email archive as we clearly forgot about this 
entirely. The timeout in your log indeed indicates it is missing a 
notification from firmware. I assume your primary interface is in 
managed mode when trying to create the p2p_dev interface. Is that correct?

brcmfmac: Failed to create interface p2p-dev-p2p0: -28 (No space left on device)

[Jörg Krause]

[-- Attachment #1: Type: text/plain, Size: 853 bytes --]

Hi Arend,

as I wrote in my previous mail ("brcmfmac: brcmf_p2p_create_p2pdev:
timeout occurred") I get a p2p0 interface when loading the brcmfmac
module with p2pon=1 (Linux kernel 4.0.5, BCM43362).

Unfortunatly, if I try to use the p2p0 interface with wpa_supplicant
2.4 I get an error:

    Failed to create interface p2p-dev-p2p0: -28 (No space left on
    device)
    nl80211: Failed to create a P2P Device interface p2p-dev-p2p0
    P2P: Failed to enable P2P Device interface

The command:

    wpa_supplicant -Dnl80211 -ip2p0 -c /etc/p2p_supplicant.conf -N 
    -Dnl80211 -iwlan0 -c /etc/wpa_supplicant.conf -ddt &

The P2P config file:
    # cat /etc/p2p_supplicant.conf 
    ctrl_interface=/var/run/p2p_supplicant

    device_name=P2P Test
    device_type=1-0050F204-1

I attached the log output from wpa_supplicant.

Best regards
Jörg Krause

Using p2pon=1 is old-school p2p, ie. it creates a regular netdev for 
doing p2p management stuff. Problem is that brcmfmac also indicates p2p 
device support. We can remove p2pon parameter or not indicate p2p dev 
support when p2pon=1.

Can you patch brcmfmac and give it a try. Need to start wpa_supplicant 
for two interface and if I recall correctly p2p0 must be specified first.

Arend

I used p2pon because the p2p0 interface is not created without it. It
fails with the error message "brcmf_p2p_create_p2pdev: timeout
occurred" as written in my previous mails. I would prefer not to use
it, so maybe we can find a solution how to get it working without it.

Can you give me a hint where to patch brcmfmac. Many thanks!

43362 firmware may have issues with regular p2p dev support so let's 
stick with p2pon for now.

Attached is patch against 4.0.5 kernel.

Subject: [PATCH] brcmfmac: disable p2pdev support when using p2pon=1

Avoid wpa_supplicant from creating a p2pdev interface when we
already have a p2p0 interface, ie. loaded the driver with p2pon=1.

I applied the patch and if I load brcmfmac with p2pon=1 I get a kernel
warning and _no_ wlan0 and p2p0 interfaces:

My bad. The patch removes p2pdev from interface modes, but it is still
listed in the interface combinations and cfg80211 will complain about
it. Have to extend the patch. I better do that after a good nights sleep.

Several ;-) Did not get to this earlier. Thanks for the reminder.

Had a closer look at wiphy_verify_combinations() and I am hopeful the 
attached patch will fix the wiphy_register() failure.

Sorry for late reply! I was busy on another topic...

I've applied your patch, but p2p interface is still not working. I
attached the debug log from wpa_supplicant.

I tested with Linux Kernel 4.0.7 and wpa_supplicant 2.4.

This is my p2p_supplicant.conf:
    ctrl_interface=/var/run/p2p_supplicant
    update_config=1

    device_name=HBM10
    device_type=1-0050F204-1

    p2p_go_ht40=1

Test with the p2p_find command:
    # wpa_cli -p /var/run/p2p_supplicant p2p_find
    Selected interface 'p2p0'
    1928.165036: p2p0: Control interface command 'P2P_FIND'
    FAIL

Best regards
Jörg Krause
