nl80211: fix some kernel doc tag mistakes

2018-06-15T11:01:31+00:00

There is a bunch of tags marking constants with &, which means struct
or enum name.  Replace them with %, which is the correct tag for
constants.

nl80211: Update ERP info using NL80211_CMD_UPDATE_CONNECT_PARAMS

2018-05-23T09:21:35+00:00

Use NL80211_CMD_UPDATE_CONNECT_PARAMS to update new ERP information,
Association IEs and the Authentication type to driver / firmware which
will be used in subsequent roamings.

In case of FILS shared key offload the parameters can change
upon roaming of which user-space needs to be notified.

Merge remote-tracking branch 'net-next/master' into mac80211-next

2018-05-23T09:05:59+00:00

Bring in net-next which had pulled in net, so I have the changes
from mac80211 and can apply a patch that would otherwise conflict.

cfg80211: further limit wiphy names to 64 bytes

2018-05-18T08:01:06+00:00

wiphy names were recently limited to 128 bytes by commit a7cfebcb7594
("cfg80211: limit wiphy names to 128 bytes").  As it turns out though,
this isn't sufficient because dev_vprintk_emit() needs the syslog header
string "SUBSYSTEM=ieee80211\0DEVICE=+ieee80211:$devname" to fit into 128
bytes.  This triggered the "device/subsystem name too long" WARN when
the device name was >= 90 bytes.  As before, this was reproduced by
syzbot by sending an HWSIM_CMD_NEW_RADIO command to the MAC80211_HWSIM
generic netlink family.

Fix it by further limiting wiphy names to 64 bytes.

cfg80211: Expose TXQ stats and parameters to userspace

2018-05-08T11:19:24+00:00

This adds support for exporting the mac80211 TXQ stats via nl80211 by
way of a nested TXQ stats attribute, as well as for configuring the
quantum and limits that were previously only changeable through debugfs.

This commit adds just the nl80211 API, a subsequent commit adds support to
mac80211 itself.

cfg80211: average ack rssi support for data frames

2018-05-07T19:37:20+00:00

Average ack rssi will be given to userspace via NL80211 interface
if firmware is capable. Userspace tool ‘iw’ can process this
information and give the output as one of the fields in
‘iw dev wlanX station dump’.

Example output :

Main use case is to measure the signal strength of a connected station
to AP. Data packet transmit rates and bandwidth used by station can vary
a lot even if the station is at fixed location, especially if the rates
used are multi stream(2stream, 3stream) rates with different bandwidth(20/40/80 Mhz).
These multi stream rates are sensitive and station can use different transmit power
for each of the rate and bandwidth combinations. RSSI measured from these RX packets
on AP will be not stable and can vary a lot with in a short time.
Whereas 802.11 ack frames from station are sent relatively at a constant
rate (6/12/24 Mbps) with constant bandwidth(20 Mhz).
So average rssi of the ack packets is good and more accurate.

cfg80211: limit wiphy names to 128 bytes

2018-04-19T13:46:34+00:00

There's currently no limit on wiphy names, other than netlink
message size and memory limitations, but that causes issues when,
for example, the wiphy name is used in a uevent, e.g. in rfkill
where we use the same name for the rfkill instance, and then the
buffer there is "only" 2k for the environment variables.

This was reported by syzkaller, which used a 4k name.

Limit the name to something reasonable, I randomly picked 128.
