Lots of conflicts, by happily all cases of overlapping
changes, parallel adds, things of that nature.

   another network interface
 * hwsim configurability to test capabilities similar
   to real hardware
 * various mesh improvements
 * various radiotap vendor data fixes in mac80211
 * finally the nl_set_extack_cookie_u64() we talked
   about previously, used for
 * peer measurement APIs, right now only with FTM
   (flight time measurement) for location
 * made nl80211 radio/interface announcements more complete

cfg80211: fix ieee80211_get_vht_max_nss()

2018-12-19T08:41:10+00:00

Fix two bugs in ieee80211_get_vht_max_nss():
 * the spec says we should round down
   (reported by Nissim)
 * there's a double condition, the first one is wrong,
   supp_width == 0 / ext_nss_bw == 2 is valid in 80+80
   (found by smatch)

nl80211: fix memory leak if validate_pae_over_nl80211() fails

If validate_pae_over_nl80211() were to fail in nl80211_crypto_settings(),
we might leak the 'connkeys' allocation. Fix this.

nl80211: Add support to notify radar event info received from STA

2018-12-18T13:13:05+00:00

Currently radar detection and corresponding channel switch is handled
at the AP device. STA ignores these detected radar events since the
radar signal can be seen mostly by the AP as well. But in scenarios where
a radar signal is seen only at STA, notifying this event to the AP which
can trigger a channel switch can be useful.
Stations can report such radar events autonomously through Spectrum
management (Measurement Report) action frame to its AP. The userspace on
processing the report can notify the kernel with the use of the added
NL80211_CMD_NOTIFY_RADAR to indicate the detected event and inturn adding
the reported channel to NOL.

cfg80211: add some missing fall through annotations

2018-12-18T12:15:08+00:00

There are talks about enabling -Wimplicit-fallthrough warnings in the
mainline and it is already enabled in linux-next.  Add all the
missing annotations to prevent warnings when this happens.

And in one case, remove the extra text from the annotation so that the
compiler recognizes it.

cfg80211: Fix busy loop regression in ieee80211_ie_split_ric()

2018-12-05T11:51:29+00:00

This function was modified to support the information element extension
case (WLAN_EID_EXTENSION) in a manner that would result in an infinite
loop when going through set of IEs that include WLAN_EID_RIC_DATA and
contain an IE that is in the after_ric array. The only place where this
can currently happen is in mac80211 ieee80211_send_assoc() where
ieee80211_ie_split_ric() is called with after_ric[].

This can be triggered by valid data from user space nl80211
association/connect request (i.e., requiring GENL_UNS_ADMIN_PERM). The
only known application having an option to include WLAN_EID_RIC_DATA in
these requests is wpa_supplicant and it had a bug that prevented this
specific contents from being used (and because of that, not triggering
this kernel bug in an automated test case ap_ft_ric) and now that this
bug is fixed, it has a workaround to avoid this kernel issue.
WLAN_EID_RIC_DATA is currently used only for testing purposes, so this
does not cause significant harm for production use cases.

crypto: drop mask=CRYPTO_ALG_ASYNC from 'cipher' tfm allocations

2018-11-20T06:26:55+00:00

'cipher' algorithms (single block ciphers) are always synchronous, so
passing CRYPTO_ALG_ASYNC in the mask to crypto_alloc_cipher() has no
effect.  Many users therefore already don't pass it, but some still do.
This inconsistency can cause confusion, especially since the way the
'mask' argument works is somewhat counterintuitive.

Thus, just remove the unneeded CRYPTO_ALG_ASYNC flags.

This patch shouldn't change any actual behavior.

{nl,mac}80211: add rssi to mesh candidates

2018-11-09T10:41:20+00:00

When peering is in userspace, some implementations may want to control
which peers are accepted based on RSSI in addition to the information
elements being sent today.  Add signal level so that info is available
to clients.
