Release 2.11 has been quite a few new features and fixes since the 2.10 release. The following ChangeLog entries highlight some of the main changes: * Wi-Fi Easy Connect - add support for DPP release 3 - allow Configurator parameters to be provided during config exchange * HE/IEEE 802.11ax/Wi-Fi 6 - various fixes * EHT/IEEE 802.11be/Wi-Fi 7 - add preliminary support * SAE: add support for fetching the password from a RADIUS server * support OpenSSL 3.0 API changes * support background radar detection and CAC with some additional drivers * support RADIUS ACL/PSK check during 4-way handshake (wpa_psk_radius=3) * EAP-SIM/AKA: support IMSI privacy * improve 4-way handshake operations - use Secure=1 in message 3 during PTK rekeying ...and many more Remove upstreamed patches: 023-ndisc_snoop-call-dl_list_del-before-freeing-ipv6-add.patch 030-driver_nl80211-rewrite-neigh-code-to-not-depend-on-l.patch 040-mesh-allow-processing-authentication-frames-in-block.patch 181-driver_nl80211-update-drv-ifindex-on-removing-the-fi.patch 182-nl80211-move-nl80211_put_freq_params-call-outside-of.patch 183-hostapd-cancel-channel_list_update_timeout-in-hostap.patch 210-build-de-duplicate-_DIRS-before-calling-mkdir.patch 253-qos_map_set_without_interworking.patch 751-qos_map_ignore_when_unsupported.patch 800-SAE-Check-for-invalid-Rejected-Groups-element-length.patch 801-SAE-Check-for-invalid-Rejected-Groups-element-length.patch 802-SAE-Reject-invalid-Rejected-Groups-element-in-the-pa.patch Other patches has been updated.

Subject: [PATCH 19/19] mesh: use deterministic channel on channel switch
|
|
|
|
This patch uses a deterministic channel on DFS channel switch
|
|
in mesh networks. Otherwise, when switching to a usable but not
|
|
available channel, no CSA can be sent and a random channel is choosen
|
|
without notification of other nodes. It is then quite likely, that
|
|
the mesh network gets disconnected.
|
|
|
|
Fix this by using a deterministic number, based on the sha256 hash
|
|
of the mesh ID, in order to use at least a different number in each
|
|
mesh network.
