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: support non-inheritance element

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

Subelement profile may specify element IDs it doesn't inherit
from the management frame. Support it.

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.

cfg80211: Use kmemdup in cfg80211_gen_new_ie()

2019-03-29T10:22:55+00:00

Use kmemdup rather than duplicating its implementation

cfg80211: fix memory leak of new_ie

2019-02-08T12:56:37+00:00

new_ie is used as a temporary storage for the generation of
the new elements. However, after copying from it the memory
wasn't freed and leaked. Free it.

cfg80211: fix the IE inheritance of extension IEs

2019-02-08T12:56:37+00:00

Extension IEs have ID 255 followed by extension ID. Current
code is buggy in handling it in two ways:
1. When checking if IE is in the frame, it uses just the ID, which
   for extension elements is too broad.
2. It uses 0xFF to mark copied IEs, which will result in not copying
   extension IEs from the subelement.

Fix both issue.

cfg80211: save multi-bssid properties

2019-02-08T12:51:50+00:00

When the new IEs are generated, the multiple BSSID elements
are not saved. Save aside properties that are needed later
for PS.
