Hi John,

This is a pull request for 3.13.

I have here a few fixes for BT Coex. One of them is a NULL pointer dereference. Another one avoids to enable a feature that can make the firmware unhappy since the firmware isn't ready for it yet. WE also avoid a WARNING that can be triggered upon association in not-so-bad cases even if the association succeeded. We add support for new NICs (not yet on the market) and bump the API so that 3.13 will be able to work with the new firmware that will be out soon hopefully. I also have a boundary check from Johannes.

I reset my tree to wireless/master as the time of this writing. I did that mainly because I needed the changes that were in -next before 3.12 went out even if 3.13-rc1 isn't out yet. I plan to rebase my tree on 3.13-rc2 (or 3.13-rc1 if this pull request makes it to 3.13-rc1 but that seems unlikely).
Tell me if you have any issues.

PATCH 1/7 iwlwifi: mvm: check sta_id/drain values in debugfs

From: Johannes Berg <[email protected]>

The station ID must be valid, if it's out of range then the array access may crash. Validate the station ID to the array length, and also validate the drain value even if that doesn't matter all that much.

PATCH 2/7 iwlwifi: pcie: refactor a bit the interrupt coalescing

In reply to Emmanuel Grumbach

From: Emmanuel Grumbach <[email protected]>

We changed the timeout for the interrupt coealescing for calibration, but that wasn't effective since we changed that value back before loading the firmware. Since calibrations are notification from firmware and not Rx packets, this doesn't change anyway - the firmware will fire an interrupt straight away regardless of the interrupt coalescing value.
Also, a HW issue has been discovered in 7000 devices series. The work around is to disable the new interrupt coalescing timeout feature - do this by setting bit 31 in CSR_INT_COALESCING.
This has been fixed in 7265 which means that we can't rely on the device family and must have a hint in the iwl_cfg structure.

Cc [email protected] [3.10+]

PATCH 4/7 iwlwifi: mvm: BT Coex - don't enable MULTI_PRIO_LUT

In reply to Emmanuel Grumbach

From: Emmanuel Grumbach <[email protected]>

This feature isn't supported by the firmware (yet). Note that settingt he values to BT_CFG_CMD is harmless if the validity bit is clear - so keep the configuration values in BT_CFG_CMD, but clear the validity bit until thes feature is enabled in the firmware.

PATCH 5/7 iwlwifi: mvm: BT Coex fix another NULL pointer dereference

In reply to Emmanuel Grumbach

From: Emmanuel Grumbach <[email protected]>

This patch is very similar to a previous fix: 22cba0c0852f

When we disassociate, mac80211 removes the station and then, it sets the bss it unsets the assoc bool in bss_info.

Since the firwmware wants it the opposite (first set the MAC context as unassoc, and only then, remove the STA of the API), we have a small period of time in which the STA in firmware doesn't have a valid ieee80211_sta pointer. During that time, iwl_mvm_vif->ap_sta_id, is still set to the STA in firmware that represent the AP.

PATCH 6/7 iwlwifi: mvm: don't WARN about unsuccessful time event

In reply to Emmanuel Grumbach

From: Emmanuel Grumbach <[email protected]>

Time event notification can have a failure status even if the time event was scheduled:
* in START notification, this can happen if the time event was scheduled later than the requested apply time.
* in STOP notification, this can happen if the time event is truncated.

Even if both happened, the offchannel packets sent during the remain on channel are very likely to have been sent. Hence, don't WARN when this happens, but rather print a discrete line in the kernel log.

PATCH 7/7 iwlwifi: bump required firmware API version for 3160/7260

In reply to Emmanuel Grumbach

From: Emmanuel Grumbach <[email protected]>

A new firmware is coming out soon with new APIs. To make sure that this new firmware won't be loaded on old driver that don't support it, it's API version has been updated to 8. In order to be able to load it, bump the API version to 8.
API version 7 is still supported and will be for another year or so.

Hi John,
This is a pull request for 3.13.
I have here a few fixes for BT Coex. One of them is a NULL pointer dereference. Another one avoids to enable a feature that can make the firmware unhappy since the firmware isn't ready for it yet. WE also avoid a WARNING that can be triggered upon association in not-so-bad cases even if the association succeeded. We add support for new NICs (not yet on the market) and bump the API so that 3.13 will be able to work with the new firmware that will be out soon hopefully. I also have a boundary check from Johannes.

I reset my tree to wireless/master as the time of this writing. I did that mainly because I needed the changes that were in -next before 3.12 went out even if 3.13-rc1 isn't out yet. I plan to rebase my tree on 3.13-rc2 (or 3.13-rc1 if this pull request makes it to 3.13-rc1 but that seems unlikely).
Tell me if you have any issues.

FWIW - since 3.13-rc1 is already out and you haven't pulled yet, I rebased this pull request --onto v3.13-rc1.

3.13-rc1 is not in the wireless tree (because it isn't in the net tree). If it is in your tree, then I can't pull from you -- sorry!

Sure - sorry... still starting with all this...
Anyway - I rebased my tree on yours - so here is a new pull request.

Can you please make sure you pull -no-ff?
It makes it easier for people to see when you pull from others rather than apply patches.

Thanks!
