cfg80211: separate get channel number from ies

2021-10-21T15:25:16+00:00

Get channel number from ies is a common logic, so separate it to a new function, which could also be used by lower driver. Signed-off-by: Wen Gong Link: https://lore.kernel.org/r/20210930081533.4898-1-wgong@codeaurora.org Signed-off-by: Johannes Berg

cfg80211: scan: use element finding functions in easy cases

2021-10-21T15:01:20+00:00

There are a few easy cases where we only check for NULL or have just simple use of the result, this can be done with the element finding functions instead. Link: https://lore.kernel.org/r/20210930131130.f27c8a7ec264.Iadb03c4307e9216e080ce513e8ad4048cd020b25@changeid Signed-off-by: Johannes Berg

cfg80211: scan: fix RCU in cfg80211_add_nontrans_list()

2021-10-01T09:02:27+00:00

The SSID pointer is pointing to RCU protected data, so we need to have it under rcu_read_lock() for the entire use. Fix this.

cfg80211: Fix possible memory leak in function cfg80211_bss_update

2021-07-23T08:38:18+00:00

When we exceed the limit of BSS entries, this function will free the new entry, however, at this time, it is the last door to access the inputed ies, so these ies will be unreferenced objects and cause memory leak. Therefore we should free its ies before deallocating the new entry, beside of dropping it from hidden_list.

cfg80211: Support hidden AP discovery over 6GHz band

2021-06-23T11:05:09+00:00

To discover a hidden AP on the 6GHz band, the probe request sent to the AP needs to include the AP's SSID, as some APs would not respond with a probe response based only on short SSID match. To support hidden AP discovery over the 6GHz band, when constructing the specific 6GHz band scan also include SSIDs that were part of the original scan request, so these can be used in the probe requests transmitted during scan.

cfg80211: scan: drop entry from hidden_list on overflow

2021-04-19T11:25:50+00:00

If we overflow the maximum number of BSS entries and free the new entry, drop it from any hidden_list that it may have been added to in the code above or in cfg80211_combine_bsses().
