* [RFC V2 0/5] cfg80211: support multiple scheduled scans
From: Arend van Spriel @ 2017-01-16 11:42 UTC (permalink / raw)
To: Johannes Berg; +Cc: linux-wireless, Arend van Spriel
After sending out the initial RFC for multiple scheduled scan support [1]
here a series that deal with it all (I hope) so including events and the
driver function call apis. Resending it due to build issue and it was based
on old mac80211-next master revision.
*Now* it does apply to the master branch of the mac80211-next repository.
Arend van Spriel (5):
nl80211: allow multiple active scheduled scan requests
nl80211: include request id in scheduled scan event messages
cfg80211: add request id parameter to .sched_scan_stop() signature
cfg80211: add request id to cfg80211_sched_scan_results() api
cfg80211: add request id in cfg80211_sched_scan_stopped{,_rtnl}() api

* [RFC V2 3/5] cfg80211: add request id parameter to .sched_scan_stop() signature
From: Arend van Spriel @ 2017-01-16 11:42 UTC (permalink / raw)

In-Reply-To: <1484566941-27000-1-git-send-email-arend.vanspriel@broadcom.com>
For multiple scheduled scan support the driver needs to know which
scheduled scan request is being stopped. Pass the request id in the
.sched_scan_stop() callback.

* [RFC V2 1/5] nl80211: allow multiple active scheduled scan requests
From: Arend van Spriel @ 2017-01-16 11:42 UTC (permalink / raw)
To: Johannes Berg; +Cc: linux-wireless, Arend van Spriel
In-Reply-To: <1484566941-27000-1-git-send-email-arend.vanspriel@broadcom.com>
This patch implements the idea to have multiple scheduled scan requests
running concurrently. It mainly illustrates how to deal with the incoming
request from user-space in terms of backward compatibility. In order to
use multiple scheduled scans user-space needs to provide a flag attribute
NL80211_ATTR_SCHED_SCAN_MULTI to indicate support. If not the request is
treated as a legacy scan.

* wpa_supplicant mesh mode issue
From: Matteo Grandi @ 2017-01-16 11:26 UTC (permalink / raw)
To: LinuxWireless Mailing List
Hi all,
I'm trying to set-up a mesh network using wpa-supplicant (already did
using iw and works fine) because I would like to implement security.
I followed the guide
https://wireless.wiki.kernel.org/en/users/drivers/ath10k/mesh?s[]=mesh&s[]=point
but I bump into some issues:
- when I set the parameter user_mpm=1 in the wpa_supplicant.conf file,
I have the llid and plid both set to 0 and the mesh points aren't able
to ping each other.
- Setting the parameter user_mpm=0 the peers can ping each other.
- If I implement the security I fall back to the same llid/plid=0 issue.
So it seems thet have user_mpm=1 and/or security implementation allows
to build the mesh, but it's impossible to ping and transmit on it.
Using user_mpm=0 allows the proper work of the mesh but only id
security is NOT used.
Is it ok to have llid/plid=0 when security is implemented or user_mpm=1?
Is someone already had this issue?
I'll be grateful for every hint!
Here my configuration file and the station dump:

Hopefully Kalle can take this through his tree, ie. wireless-drivers-next.

BCM43455 is a more recent revision of the BCM4345. Some of the BCM43455
got a dedicated SDIO device ID which is currently not supported by
brcmfmac.
Adding the new sdio_device_id to brcmfmac is enough to get the BCM43455
supported because the chip itself is already supported (due to BCM4345
support in the driver).

There is no CONFIG_PCI_SET_MWI in the kernel. This patch is either not
needed (pci subsystem has own PCI_DISABLE_MWI define) or wrong (we
should not call this function for some devices).

Hi
I looked more detail in the patches and now I think shared mem
and 16 hw beacons patches are not needed. Explanation is below.
Sorry for not pointing this before.

I just check that RT3593 (USB) device send beacon on AP mode when it is
configured previous way. I believe on RT3883 old way of configuring
beacons will work as well.
This change is only needed if we have to configure more than 8 beacons
i.e. add support to more than 8 APs per device. However there is no
patch increasing number of supported AP to 16 (by changing max_ap_intf),
so apparently nobody use this feature.
Hence I believe shared mem and 16 hw beacons is not needed and I prefer
to not add support for 16 APs per device with cost of adding this
additional complexity to the driver.
