Honestly all the conflicts were simple overlapping changes,
nothing really interesting to report.

cfg80211: use BIT_ULL in cfg80211_parse_mbssid_data()

2019-06-14T13:46:33+00:00

The seen_indices variable is u64 and in other parts of the code we
assume mbssid_index_ie[2] can be up to 45, so we should use the 64-bit
versions of BIT, namely, BIT_ULL().

cfg80211: Add a function to iterate all BSS entries

2019-06-14T12:16:02+00:00

Add a function that iterates over the BSS entries associated with a
given wiphy and calls a callback for each iterated BSS. This can be
used by drivers in various ways, e.g., to evaluate some property for
all the BSSs in the medium.

cfg80211: Handle bss expiry during connection

2019-05-28T07:35:39+00:00

If the BSS is expired during connection, the connect result will
trigger a kernel warning. Ideally cfg80211 should hold the BSS
before the connection is attempted, but as the BSSID is not known
in case of auth/assoc MLME offload (connect op) it doesn't.

For those drivers without the connect op cfg80211 holds down the
reference so it wil not be removed from list.

Fix this by removing the warning and silently adding the BSS back to
the bss list which is return by the driver (with proper BSSID set) or
in case the BSS is already added use that.

The requirements for drivers are documented in the API's.

cfg80211: don't pass pointer to pointer unnecessarily

2019-04-26T11:02:11+00:00

The cfg80211_merge_profile() and ieee802_11_find_bssid_profile() are
a bit cleaner if we just pass the merged_ie pointer instead of a pointer
to the pointer.

This isn't a functional change, it's just a clean up.

cfg80211: support profile split between elements

2019-04-26T11:02:11+00:00

Since an element is limited to 255 octets, a profile may be split
split to several elements. Support the split as defined in the 11ax
draft 3. Detect legacy split and print a net-rate limited warning,
since there is no ROI in supporting this probably non-existent
split.

cfg80211: don't skip multi-bssid index element

2019-04-26T11:02:11+00:00

When creating the IEs for the nontransmitted BSS, the index
element is skipped. However, we need to get DTIM values from
it, so don't skip it.
