Hi Johannes,

After merging the mac80211-next tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/net/wireless/mediatek/mt76/mt76x2_main.c:539:19: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types]
  .wake_tx_queue = mt76_wake_tx_queue,
                   ^
drivers/net/wireless/mediatek/mt76/mt76x2_main.c:539:19: note: (near initialization for 'mt76x2_ops.wake_tx_queue')

Caused by commits

  17f1de56df05 ("mt76: add common code shared between multiple chipsets")
  7bc04215a66b ("mt76: add driver code for MT76x2e")

from the wireless-drivers-next tree interacting with commit

  e937b8da5a59 ("mac80211: Add TXQ scheduling API")

from the mac80211-next tree.

I applied the below hack merge fix ... please let me know if something
more/better is required.  Someone needs to remember to tell Dave when
these trees meet in his tree.

Hi Stephen,

Thanks!

Felix made me aware of this yesterday evening and said he's going to
work out the required changes to mt76.

Kalle and I will make sure to submit the trees to Dave one by one so he
doesn't have to deal with it :)

Unfortunately, this might take a few days to resolve.

Looks pretty much right to me - perhaps for safety there should be a
NULL check on txq, but OTOH when you get here it should be non-NULL.

Sorry for the inconvenience, I hadn't realized mt76 went in now.

Note that while this will fix compilation it probably won't work right.
next_txq() is not guaranteed to return the same txq as was previously
passed in the wake_tx_queue() argument, so if this is the only place the
driver calls next_txq(), things are likely going to break.

Rather, the driver should call next_txq() whenever it schedules queues
instead of doing its own internal scheduling.

> Sorry for the inconvenience, I hadn't realized mt76 went in now.

Yeah, hadn't expected these streams to cross either. If Felix is looking
into this that is great; let me know if you need me to do anything else
on the mac80211 side. :)

I did ask[1] if everyone are ok that I apply mt76 and I didn't get any
comments, I guess I need to make more noise next time when I'm applying
a new driver.

Huh, did actually see that. But was not aware that Johannes had already
merged my patches; have been caught up in other stuff since netdev, so
have not been paying that close attention... Sorry about that, should
have pointed out the potential conflict :)

Yeah, I would like to request a marching band to my apartment next time,
please. I'll send you my address off list... ;)

I would remove the commented out code '/* if
(ieee80211_is_probe_resp(mgmt->frame_control)) */', otherwise looks good
to me.

Yeah, I guess I can do that too.

Maybe I'll do that and link to both of your resolutions, they both look
good :)

Hi Stephen,

Thanks for the heads-up, also on the merge issue.

I'll pull back net-next and fix this.

Hi all,

After merging the mac80211-next tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/net/wireless/ath/ath9k/debug.c: In function 'read_file_misc':
drivers/net/wireless/ath/ath9k/debug.c:741:35: error: 'struct ath9k_vif_iter_data' has no member named 'nwds'
  741 |       iter_data.nmeshes, iter_data.nwds);
      |                                   ^

Caused by commit

  f532b9716eeb ("ath9k: remove WDS code")

I have used the mac80211-next tree from next-20201110 for today.

Ok, this one looks good to me.

Otherwise wilc_update_mgmt_frame_registrations() will think there are no
changes whatsoever, and do nothing.

Looks good. But I have a couple of questions:

- why cleanup vif->mgmt_frame_reg in wilc_mac_open ?

- previously wilc_wfi_p2p_rx was called only for PROBE_REQ and ACTION,
  now it will be called for all the other registred frames as well

Yeah. I forgot about staging. I guess I'll throw in a quick fix.

Thanks for the heads-up.

Hm. I'm using Debian 5.3.1-8.

That's true, but since I can't test it I'll just solve this
differently. We'll never be able to insert anything into the middle, so
we can also just BUILD_BUG_ON() the ARRAY_SIZE() and do the code a bit
differently.

Thanks,

Hi Johannes,

After merging the mac80211-next tree, today's linux-next build (x86_64
allmodconfig) failed like this:

Caused by commit

  1f86443b4ffe ("net: rfkill: add rfkill_find_type function")

Maybe the compiler version matters?  I am using gcc v5.2.0.

Though, it seems to be that "!rfkill_types[NUM_RFKILL_TYPES - 1]" is
not a constant expression since

static const char *rfkill_types[NUM_RFKILL_TYPES]

does not stop "rfkill_types[NUM_RFKILL_TYPES - 1]" being modified at
run time. I think that you might need:

static const char * const rfkill_types[NUM_RFKILL_TYPES]

I have used the mac80211-next from next-20160223 for today.
