Ok. Thanks Ben. will do. Just curious. I am not able to get the reg.
domain codes in TPC by googling. Do you know where I can get those?
What is the reg. domains 0x20 and 0x58 value points to?
Thanks

Hi Daniel,
I was able to get a NXP NPC300 NFC device run on Lenovo ThinkPad T470.
Look at the patchset "[PATCH v2 00/12] NFC: nxp-nci: clean up and
support new ID".
I have tested on top of Linux v5.1.1.
Here I have set...
scripts/config -m NFC_NCI -m NFC_NXP_NCI -m NFC_NXP_NCI_I2C -e
PINCTRL_SUNRISEPOINT
Please give this a try and report.
For details see the below references.
Thanks.

My laptop is the first one I have with a NFC reader, so I'm not used to
test this as it was not working yet.
I booted the machine with a 5.1.1, the series applied on top, and the
config options set as mentioned above.
The nxp-nci kernel module is loaded and neard is installed.
I used the sniffing tool with the command libnfc -d nfc0 -n but when
passing my NFC devices on the laptop's NFC mark, nothing happens.
Is that correct?

Hi Daniel,
I am new to the topic Linux NFC.
I have installed neard (daemon) v0.16 and neard-tools from Debian/buster AMD64.
root@iniza:~# systemctl is-active neard.service
active
root@iniza:~# nfctool --list
nfc0:
Tags: [ ]
Devices: [ ]
Protocols: [ Felica MIFARE Jewel ISO-DEP NFC-DEP ]
Powered: No
RF Mode: None
lto: 150
rw: 15
miux: 2047
root@iniza:~# nfctool --poll -d nfc0
Start polling on nfc0 as initiator
...
Throwing my YubiKey Neo-5 NFC on my ThinkPad T470 NFC sticker shows me...
Targets found for nfc0
Tags: [ tag0 ]

Hope that helps.

I have:

I cannot say much to this.
For the sake of completeness:
I have the patch "NFC: fix attrs checks in netlink interface" applied.

hi Ben:
Looks like ./sys/kernel/debug/ieee80211/phy2/ath10k/cal_data is junk
for both the 5Ghz radios even though the
pre-cal-pci-0000:01:00.0.bin/pre-cal-ahb-a800000.wifi.bin is correct.
The 2Ghz cal_data seem to be correct and match the pre-cal-ahb-a000000.wifi.bin.
Openwrt seem to do the right thing in setting the countrycode.
I am clueless. Any pointers would help.
Thanks

Same result for the modinfo.

So the first time I run:
[mark]
nfctool -d nfc0 -p
Start polling on nfc0 as initiator
With an error in syslog/dmesg:
nci: nci_ntf_packet: unknown ntf opcode 0x0
The second time:
nfctool -p -d nfc0
Protocol error
With an error in syslog/dmesg:
nci: nci_start_poll: failed to set local general bytes
Then I do:
nfctool -0 -d nfc0
it returns to point [mark]

I cannot help with (debugging) nci.
I had all I2C and GPIO debug Kconfigs enabled to see a bit more
informations in the logs.
Maybe that helps you.

It seems to be entirely ath10k's fault, and quite possibly our
documentation, but we probably should have local_bh_disable() there
rather than try to do u64_stats_update_begin_irqsave() in some path that
really doesn't need it.
This is going to be whack-a-mole otherwise - the TX path in mac80211
really expects to not be interrupted by softirqs.

Am I correct that "NPC100" is "PN547" and "NPC300" is "PN548"?

Shouldn't this check if 4addr is actually enabled too, like here:

I also wonder if we shouldn't go "all in" and actually make the check
something like
check_interface_allowed(iftype, 4addr):
if (iftype == AP_VLAN && 4addr)
return wiphy.flags & WIPHY_FLAG_4ADDR_AP;
else return wiphy.interface_modes & BIT(iftype);
i.e. make it "you must have WIPHY_FLAG_4ADDR_AP to use 4-addr AP_VLAN
interfaces", rather than "also allow it in this case".
That would seem like the clearer semantics to me?

Please share the dump, I don't think this should be happening. I think
this warning did what it was supposed to, uncover a bug; rather than
remove the warning we should fix the bug.

I don't buy this, it's just a WARN_ON_ONCE().

I agree, but right now I'm inclined to think it's a bug elsewhere rather
than normal operation.

In multiple SSID cases, it takes time to prepare every AP interface
to be ready in initializing phase. If a sta already knows everything it
needs to join one of the APs and sends authentication to the AP which
is not fully prepared at this point of time, AP's channel context
could be NULL. As a result, warning message occurs.
Even worse, if the AP is under attack via tools such as MDK3 and massive
authentication requests are received in a very short time, console will
be hung due to kernel warning messages.
If this case can be hit during normal functionality, there should be no
WARN_ON(). Those should be reserved to cases that are not supposed to be
hit at all or some other more specific cases like indicating obsolete
interface.

* [PATCH] NFC: Orphan the subsystem
From: Johannes Berg @ 2019-05-14 9:02 UTC (permalink / raw)
To: linux-wireless, netdev; +Cc: Samuel Ortiz
Samuel clearly hasn't been working on this in many years and
patches getting to the wireless list are just being ignored
entirely now. Mark the subsystem as orphan to reflect the
current state and revert back to the netdev list so at least
some fixes can be picked up by Dave.

Err, what was the point in sending v2 without any changes?

Hi Johannes,
I was planning to use WARN_ON_ONCE() in the first place to replace
WARN_ON() then after some discussion, we think removing it could be
better. So the first patch was based on my first version which is sent
incorrectly. Please check again.
Sorry for the confusing.

Oops, I didn't pay attention to the - code.
I guess changing it to WARN_ON_ONCE() makes sense, but as per my earlier
email I'm really not sure about removing it entirely, it doesn't seem
like a valid scenario and we should take steps elsewhere to prevent it.
