This patchset enables DFS channels in mesh mode along with
CAC and channel switch.
It's been verified that works for non-dfs channels, dfs channels,
w/wo encryption (none and SAE), radar detection, channel switch,
and mesh re-association after channel switch.
Also this patch series passes all the test cases in wpas_mesh.
Only left area to cover is in the case when multiple mesh points
detect radar at the same time, but they select different channels.
To cover the case I think we need a private patch for it,
because current 802.11s standard does not address it how to handle.
* v2: corrected wrong sender's email.
* v3: rebased on top of "mesh: Properly handle sae_password".
fix compiler warnings on unused variables and parentheses.
* v4: updated "allow mesh to send channel switch request" patch
based on "2dd5fbbff wpa_supplicant: Rename wpas_event_*".
fix channel switch error during CAC.
* v5: some changes in "Allow DFS channels to be selected"
moves to "consider mesh interface on dfs event handler" to
group the similar changes together.
* v6: fixed memory leak.
updated ieee80211_is_dfs() usage based on "d239ab396 DFS:
Mark channels required DFS based on reg-domain" commit.
removed "mesh: allow mesh to send channel switch request"
which is already merged to master branch.
move "mesh: inform kernel driver DFS handler in userspace"
patch to the last.
* v7: dropped pri/sec channel swap related patches
fixed "wpas_mesh_secure_sae_missing_password" test case
fixed memory leak at wpa_driver_nl80211_send_action()
use operating channel to determine DFS channel
* v8: fixed failed test cases in wpas_mesh.
re-introduce a pri/sec channel swap patch
Peter Oh (16):
mesh: factor out mesh join function
mesh: factor out rsn initialization
tests: Update mesh_oom to match implementation change
mesh: relocate RSN init function
mesh: use setup completion callback to complete mesh join
mesh: reflect country setting to mesh configuration
mesh: apply channel attributes before setup interface
mesh: update ssid->frequency as pri/sec channel switch
mesh: set interface type to mesh before setting interface
mesh: set mesh center frequency
mesh: consider mesh interface on dfs event handler
mesh: Allow DFS channels to be selected if dfs is enabled
mesh: do not set offchanok on DFS channels in non-ETSI
mesh: fix channel switch error during CAC
mesh: don't allow pri/sec channel switch
mesh: inform kernel driver DFS handler in userspace
